For the repair of complex equipment (computers, power equipment), proprietary service is increasingly used, which is carried out by special units of the manufacturer. Currently, the processing enterprises operate a system of scheduled preventive maintenance of equipment (TSHR), which is a progressive form of organization of repair work. PPR is a set of organizational and technical measures aimed at maintaining equipment in working order and preventing its emergency exit from operation. Each machine, after working out a certain number of hours, stops and undergoes preventive inspection or repair, the frequency of which is determined by the design features and operating conditions of the machines. The PPR system at RUE MZIV provides for the following types of services: 1.

Equipment PPR system

In some industries, I happened to see how they remove an old, unusable bearing and put another old bearing on the assembly, of course, such an attitude to the financing of production will also cause a corresponding return on production.

The quality of repairs by personnel, with poor-quality performance, breakdowns will be more frequent. In this case, it will be necessary to schedule repairs and equipment maintenance more often.
Repair planning quality, qualification of equipment repair organizers. The organizers of equipment repairs in production include a mechanic, and on large production lines, even a completely department of the chief mechanic.

Drawing up a schedule for scheduled preventive maintenance of equipment

It consists in replacing individual worn parts, eliminating defects, performing lubrication and fastening operations, etc. Overhaul is a repair carried out to restore the life of a product with the replacement or restoration of any of its parts. Major and current repairs can be planned and unplanned.

Attention

Planned repairs are being carried out on schedule. Unscheduled repairs are carried out in order to eliminate the consequences of sudden failures and breakdowns. Retail store equipment in most cases it undergoes scheduled overhaul. Planned overhaul is not provided for equipment that does not have mechanical wear (for example, thermal) during operation.

All these works are designed to maintain the operability of machines and devices until the next scheduled repair.
The preventive maintenance system includes the following types technical repair and maintenance: weekly maintenance, monthly maintenance, annual scheduled preventive maintenance, Annual scheduled preventive maintenance is carried out in accordance with the annual schedule of equipment maintenance. Scheduling PPR Annual schedule of scheduled preventive maintenance, on the basis of which the need for repair personnel, materials, spare parts, components is determined. It includes each unit subject to major and current repairs.
To draw up an annual preventive maintenance schedule (PPR schedule), we need standards for the frequency of equipment repair.
Very often, such repairs are called equipment maintenance (scheduled preventive maintenance) or equipment maintenance (equipment maintenance).

Major repairs.

Here you need to partially disassemble the mechanism, replace and restore worn parts. It is performed without removing the mechanism from the foundation. 5. Overhaul, consisting in replacing worn out parts and assemblies, checking and adjusting machines and restoring them in accordance with technical conditions.

Overhaul involves complete disassembly of the equipment with removal, if necessary, from the foundation. Inspections, current and major repairs are carried out by special repair personnel with the involvement of service staff. At the heart of the preparation of the PM plan are the standards and structure of the repair cycle.

The repair cycle is the operating time of the machine from the beginning of its commissioning to the first major overhaul. It depends on the durability of the parts and the operating conditions of the equipment.
These data can be found in the manufacturer's passport data, if the plant specifically regulates this, or use the reference book "Maintenance and repair system". There is a certain amount of equipment. All this equipment must be included in the PPR schedule. Column 1 indicates the name of the equipment, as a rule, concise and understandable information about the equipment.
In column 2 - the number of equipment In column 3-4 - the resource standards between major repairs and current ones are indicated. (See Appendix 2) Columns 5-6 - the complexity of one repair (see Table 2 Appendix 3) based on the list of defects. In columns 7-8 - the dates of the last major and current repairs are indicated (conditionally we take the month of January of the current year) In columns 9-20, each of which corresponds to one month, the symbol indicates the type of planned repair: K - major, T - current.

Info

For effective work equipment at RUE MZIV requires a clear organization of its material and technical maintenance. A large number of this is assigned to the organization of equipment repair. The essence of the repair is to preserve and restore the performance of equipment and mechanisms by replacing or restoring worn parts and adjusting mechanisms.

Important

Annually more than 10-12% of the equipment is overhauled, 20-30% - medium and 90-100% - small. The cost of repair and maintenance of equipment is more than 10% of the cost of manufactured products. Over the entire service life of the machine, the cost of repairing it is several times higher than its original cost.

The main task of the repair facilities is to keep the equipment in a technically sound condition, which ensures its uninterrupted operation.

The annual fund of working time of one worker is 1,860 hours, the rate of fulfillment of the output rate is 0.95, the shift of equipment is 1.5.
Equipment that does not meet at least one of the requirements established by operational documentation, standards (GOST), technical conditions (TU) is considered to be faulty. Faults include a decrease in the productivity and economy of machines, loss of accuracy, deviations in technological processes(beyond the permissible limits). The reliability of the equipment is determined by the reliability, durability, maintainability and preservation.

Reliability is the property of equipment to remain operational for a certain operating time, that is, work without failure for a given period of time. Durability reflects such a property of the equipment as maintaining operability before major repairs or before retirement. Maintainability is the ability of equipment to prevent, detect, and correct failures and malfunctions.

The main stages of PPR equipment

Preventive well-designed repairs provide for:

Planning;

Preparation of electrical equipment for scheduled repair;

Carrying out scheduled repairs;

Carrying out activities related to the planned maintenance and repair.

The system for preventive maintenance of equipment includes a couple of stages:

1. Stage between repairs

It is carried out without disrupting the operation of the equipment. Includes: systematic cleaning; systematic lubrication; systematic inspection; systematic adjustment of the operation of electrical equipment; replacement of parts that have a short service life; elimination of small malfunctions.

In other words, this is preventive maintenance, which includes daily inspection and maintenance, while it must be properly organized in order to maximize the life of the equipment, maintain high-quality work, and reduce the cost of scheduled repairs.

The main work performed at the overhaul stage:

Tracking the status of equipment;

Conduct by employees of the rules of appropriate use;

Daily cleaning and lubrication;

Timely elimination of minor breakdowns and adjustment of mechanisms.

2. Current stage

Preventive maintenance of electrical equipment is most often carried out without disassembling the equipment, only its work stops. Includes the elimination of breakdowns that occurred during the period of work. At the current stage, measurements and tests are carried out, with the help of which equipment flaws are identified at an early stage.

The decision on the suitability of electrical equipment is made by the repairers. This ruling is based on a comparison of the test findings during routine maintenance. In addition to scheduled repairs, to eliminate defects in the equipment, work is performed outside the plan. They are carried out after the exhaustion of the entire resource of the equipment.

3. Stage middle

It is carried out for the complete or partial restoration of old equipment. Includes disassembly of assemblies intended for viewing, cleaning mechanisms and eliminating identified defects, replacing some quickly wearing parts. The middle stage is carried out no more than once a year.

The system at the middle stage of preventive maintenance of equipment includes the installation of the cycle, volume and sequence of work in accordance with the normative and technical documentation. The middle stage affects the maintenance of the equipment in good condition.

4. Overhaul

It is carried out by opening electrical equipment, its full check with inspection of all details. Includes tests, measurements, elimination of identified malfunctions, as a result of which the modernization of electrical equipment is carried out. As a result of the overhaul, the technical parameters of the devices are completely restored.

Overhaul is possible only after the overhaul stage. To conduct it, you must do the following:

Draw up work schedules;

Conduct preliminary inspection and verification;

Prepare documents;

Prepare tools and necessary replacement parts;

Carry out fire-fighting measures.

Overhaul includes:

Replacement or restoration of worn out mechanisms;

Modernization of any mechanisms;

Performing preventive checks and measurements;

Carrying out work related to the elimination of minor damage.

Malfunctions discovered during the equipment check are eliminated during subsequent repairs. And breakdowns of an emergency nature are eliminated immediately.

PPR systems and its basic concepts

The system of preventive maintenance of power equipment (hereinafter referred to as the PPREO System) is a complex of methodological recommendations, norms and standards designed to ensure efficient organization, planning and carrying out maintenance (MOT) and repair of power equipment. The recommendations given in this PPR EO System can be used at enterprises of any type of activity and form of ownership, using similar equipment, taking into account the specific conditions of their work.

The planned preventive nature of the EO PPR System is implemented: by carrying out equipment repairs with a given frequency, the timing and material and technical support of which are planned in advance; carrying out maintenance operations and monitoring the technical condition aimed at preventing equipment failures and maintaining its serviceability and operability in the intervals between repairs.

The PPR EO system was created taking into account the new economic and legal conditions, and in technical terms, with the maximum use of: the possibilities and advantages of the aggregate repair method; the whole range of strategies, forms and methods of maintenance and repair, including new means and methods of technical diagnostics; modern computer technology and computer technologies for collecting, accumulating and processing information about the state of equipment, planning repair and preventive actions and their material and technical support.

The action of the PPR EO System applies to all equipment of power and technological shops of enterprises, regardless of the place of its use.

All equipment operated at enterprises is subdivided into basic and non-basic. The main equipment is equipment, with the direct participation of which the main energy and technological processes of obtaining a product (final or intermediate) are carried out, and the failure of which leads to the termination or a sharp reduction in the output of products (energy). Non-core equipment ensures the full flow of energy and technological processes and the operation of the main equipment.

Depending on the production significance and functions performed in energy and technological processes, equipment of the same type and name can be classified as both primary and non-primary.

The PPR EO system provides that the need for equipment for repair and preventive actions is satisfied by a combination different types Maintenance and scheduled repairs of equipment, differing in frequency and scope of work. Depending on the production significance of the equipment, the impact of its failures on the safety of personnel and the stability of energy technological processes, repair effects are implemented in the form of regulated repairs, repairs based on operating time, repairs based on technical conditions, or in the form of a combination of these.

DRAFTING A PREVENTIVE REPAIR SCHEDULE (PPR)

In order to ensure reliable operation of equipment and prevent malfunctions and wear, enterprises periodically carry out scheduled preventive maintenance of equipment (PPR). It allows you to carry out a number of works aimed at restoring equipment, replacing parts, which ensures economical and continuous operation of the equipment.

The alternation and frequency of scheduled preventive maintenance (PPR) of equipment is determined by the purpose of the equipment, its design and repair features, dimensions and operating conditions.

The equipment is stopped for routine maintenance while it is still in working order. This (planned) principle of withdrawing equipment for repair allows you to make the necessary training to equipment shutdown - both on the part of the service center specialists and on the part of the customer's production personnel. Preparation for scheduled preventive maintenance of equipment consists in clarifying equipment defects, selecting and ordering spare parts and parts that should be replaced during repair.

Such training allows the full scope of repair work to be carried out without disrupting the normal operation of the enterprise.

Competent execution of the PPR involves:

· Planning of scheduled preventive maintenance of equipment;
· Preparation of equipment for scheduled preventive maintenance;
· Carrying out scheduled preventive maintenance of equipment;
· Carrying out activities related to scheduled preventive maintenance and equipment maintenance.

Routine equipment repair includes the following stages:

1. Overhaul stage of service.

The overhaul stage of equipment maintenance is carried out mainly without interrupting the operation of the equipment itself.

The overhaul phase of equipment maintenance consists of:

· Systematic cleaning of equipment;
· Systematic lubrication of equipment;
· Systematic inspection of equipment;
· Systematic adjustment of equipment operation;
· Change of parts with a short service life;
· Elimination of minor faults and defects.

The overhaul phase of maintenance is prevention in other words. The overhaul phase of maintenance includes daily inspection and maintenance of the equipment and must be properly organized in order to:

· Dramatically extend the period of operation of the equipment;
· Maintain excellent quality of work;
· Reduce and accelerate the costs associated with scheduled maintenance.

The overhaul phase of maintenance consists of:

· Tracking the condition of the equipment;
· Carrying out the rules of proper operation by the workers;
· Everyday cleaning and lubrication;
· Timely elimination of minor breakdowns and regulation of mechanisms.

The overhaul stage of service is carried out without stopping the production process. This stage of maintenance is carried out during interruptions in the operation of the equipment.

2. The current stage of scheduled preventive maintenance.

The current stage of preventive maintenance is often carried out without opening the equipment, temporarily stopping the operation of the equipment. The current stage of preventive maintenance consists in the elimination of breakdowns that appear during operation and consists of inspection, lubrication of parts, and equipment cleaning.

The current stage of scheduled preventive maintenance precedes overhaul. At the current stage of preventive maintenance, important tests and measurements are carried out, leading to the identification of equipment flaws at an early stage of their appearance. Having assembled the equipment at the current stage of preventive maintenance, it is adjusted and tested.

Decree on the suitability of the equipment for further work is made by the repairmen, based on a comparison of the test results at the current stage of preventive maintenance with the existing standards, the results of past tests. Equipment that cannot be transported is tested using electrotechnical mobile laboratories.

In addition to scheduled preventive maintenance, work outside the plan is carried out to eliminate any flaws in the operation of the equipment. These works are carried out after the entire working resource of the equipment has been exhausted. Also, to eliminate the consequences of accidents, emergency recovery repairs are carried out, which requires the immediate termination of equipment operation.

3. The middle stage of scheduled preventive maintenance

The middle stage of preventive maintenance is intended for partial or complete restoration of used equipment.

The middle stage of preventive maintenance is to disassemble equipment assemblies for viewing, cleaning parts and eliminating identified flaws, changing parts and assemblies that wear out quickly and which do not ensure proper use of the equipment until the next major overhaul. The middle stage of scheduled preventive maintenance is carried out no more than once a year.

The middle stage of preventive maintenance includes repairs, in which the normative and technical documentation establishes the cyclicality, volume and sequence of repair work, even regardless of the technical condition in which the equipment is located.

The middle stage of preventive maintenance affects the fact that the operation of the equipment is maintained as normal, there is little chance that the equipment will fail.

4. Overhaul

Overhaul of the equipment is carried out by opening the equipment, checking the equipment with a meticulous inspection of the "insides", tests, measurements, elimination of identified breakdowns, as a result of which the equipment is modernized. Overhaul provides the restoration of the original technical characteristics of the equipment.

Overhaul of the equipment is carried out only after the overhaul period. For its implementation, it is necessary to carry out the following steps:

· Scheduling of work performance;
· Carrying out preliminary inspection and verification;
· Preparation of documentation;
· Preparation of tools, spare parts;
· Implementation of fire-prevention and safety measures.

Equipment overhaul consists of:

· In replacement or restoration of worn-out parts;
· Modernization of any details;
· Performing preventive measurements and checks;
· Carrying out works on elimination of minor damages.

Defects that are discovered during the inspection of the equipment are eliminated during the subsequent overhaul of the equipment. Breakdowns that are of an emergency nature are eliminated immediately.

The specific type of equipment has its own frequency of scheduled preventive maintenance, which is regulated by the rules of technical operation.

Measures under the SPR system are reflected in the relevant documentation, with strict consideration of the availability of equipment, its condition and movement. The list of documents includes:

· Technical data sheet for each mechanism or its duplicate.
· Equipment accounting card (annex to the technical passport).
· Annual cyclical schedule of equipment repair.
· Annual plan-estimate of equipment overhaul.
· Monthly plan-report of equipment repair.
· Acceptance certificate for overhaul.
· Replaceable log of malfunctions of technological equipment.
· Extract from the annual PPR schedule.

On the basis of the approved annual plan-schedule of PPR, a nomenclature plan for the production of capital and current repairs is drawn up, broken down by months and quarters. Before starting overhaul or current repairs, it is necessary to clarify the date of setting the equipment for repair.

The annual PPR schedule and tables of initial data are the basis for drawing up an annual budget plan, which is developed twice a year. The annual amount of the plan-estimate is divided by quarters and months, depending on the period of capital repairs according to the PPR schedule of the given year.

Based on the plan-report, the accounting department is provided with a report on the expenses incurred for capital repairs, and the manager is provided with a report on the implementation of the nomenclature repair plan according to the annual PM schedule.

Currently, for scheduled preventive maintenance (PM), computer and microprocessor equipment (installations, stands, devices for diagnostics and testing of electrical equipment) are increasingly being used, which affect the prevention of equipment wear and reduce equipment repair times, reduce repair costs, and improves the efficiency of electrical equipment operation.

Preventive maintenance is the easiest and most reliable way to plan repairs.

The main conditions that ensure a planned preventive relationship regarding the repair of equipment are as follows:

The main need for electrical equipment for repair is satisfied due to scheduled repairs performed after a specific number of hours worked by it, due to which a periodically repeating cycle is formed;

Each scheduled preventive repair of electrical installations is carried out to the extent necessary to eliminate all existing defects, as well as to ensure the natural operation of the equipment until the next scheduled repair. The term of scheduled repairs is determined according to the established periods;

The organization of scheduled preventive maintenance and control is based on the usual scope of work, the implementation of which ensures the efficient condition of the equipment;

The normal scope of work is determined by the established optimal periods between scheduled periodic repairs;

Between scheduled periods, electrical equipment undergoes scheduled inspections and checks, which are a means of prevention.

The frequency and alternation of scheduled equipment repair depends on the purpose of the equipment, its design and repair features, dimensions and operating conditions. Preparation for scheduled repair is based on clarification of defects, selection of spare parts and spare parts that will need to be replaced during repair. An algorithm for carrying out this repair is specially created, which ensures uninterrupted operation during the repair. Such an approach in preparation makes it possible to carry out a complete repair of equipment without disrupting the usual work of production.

Preventive well-designed repairs provide for:

Planning;

Preparation of electrical equipment for scheduled repair;

Carrying out scheduled repairs;

Carrying out activities related to scheduled maintenance and repair.

The system for preventive maintenance of equipment includes a couple of stages:

1. Stage between repairs

The main work performed at the overhaul stage:

Tracking the status of equipment;

Conduct by employees of the rules of appropriate use;

Daily cleaning and lubrication;

Timely elimination of minor breakdowns and adjustment of mechanisms.

2. Current stage

3. Stage middle

4. Overhaul

It is carried out by opening the electrical equipment, its full inspection with inspection of all parts. Includes tests, measurements, elimination of identified malfunctions, as a result of which the modernization of electrical equipment is carried out. As a result of the overhaul, the technical parameters of the devices are completely restored.

Overhaul is possible only after the overhaul stage. To conduct it, you must do the following:

Draw up work schedules;

Conduct a preliminary inspection and check;

Prepare documents;

Prepare tools and necessary replacement parts;

Carry out fire-fighting measures.

Overhaul includes:

Replacement or restoration of worn out mechanisms;

Modernization of any mechanisms;

Performing preventive checks and measurements;

Carrying out work related to the elimination of minor damage.

Malfunctions discovered during the equipment check are eliminated during subsequent repairs. And breakdowns of an emergency nature are eliminated immediately.

Each separate species equipment has its own frequency of scheduled preventive maintenance, which is regulated by the Technical Operation Rules. All activities are reflected in the documentation, strict records are kept of the availability of equipment, as well as its condition. According to the approved annual plan, a nomenclature plan is created, which reflects the implementation of capital and current repairs. Before starting current or major repairs, it is necessary to clarify the date of installation of electrical equipment for repair.

Schedule of the preventive maintenance year- this is the basis for drawing up a budget plan for the year, developed 2 times a year. The sum of the year of the plan-estimate is divided by months and quarters, it all depends on the period of the overhaul.

Today, for the system of scheduled preventive maintenance of equipment, computer and microprocessor technology (structures, stands, installations for diagnostics and tests) is most often used, which affects the prevention of equipment wear, lower repair costs, and also contributes to an increase in operating efficiency.

Production project PPR works - this is organizational and technological documentation, containing the technology and organization of the preparatory and main types of construction and installation work at the construction site, quality control and requirements for acceptance, work of the final period, measures for labor protection and safety in accordance with the current regulatory and technical documents, as well as the standards of the Customer's organization. Does not apply to either work or project documentation object, which are only the basis for the development of PPR. Prepared before the start of all construction and installation work.

PPR (decoding of the abbreviation - project for the production of works) is one of the executive documents required for the construction, reconstruction and overhaul of the facility. Its main purpose is to choose the technology of construction and installation and / or repair work, which allows the most rational use of material, logistical and labor resources with provision general security... Without this document, it is impossible to properly organize and start the workflow. With its help it is possible to:

reduce the cost of materials and equipment;
ensure the safety of work;
reduce risks;
ensure compliance with the terms of construction or repair of the facility.

In 2019, when drawing up the PPR, it is necessary to take into account only the changes made to the NTD (Town Planning Code, RD guidelines, JV rules, building codes and SNiP rules, state standards GOST, etc.). The requirements remain the same as in 2018, 2017 and previous years. Of course, it will be wrong to use ready-made standard documents common on the Internet, since in 2018 - 2019 many changes were made to the NTD and old ones were replaced. Every year, a bunch of documents are updated and it becomes difficult to undertake the development of a project for the production of work on its own.

The explanatory note is the main part and consists of the most important sections. It includes the entire organizational sequence of the work performed and provides links to flow charts by type of work performed. Engineering support of construction, taking into account the duration, the composition of the working personnel, the number of machines and mechanisms, are given in the preparatory period.

In the appendix to the PPR, work schedules are inserted that determine the technical and economic indicators of construction. The schedule is drawn up in accordance with the contract for the execution of work on the object without deviations, regardless of the duration specified in the construction organization project. Delivery schedules and requirements are divided by week, month or quarter depending on the construction time.

Who develops a project for the production of PPR works

The development of projects for the production of PPR works is carried out by a general contracting organization, or by order of a specialized organization. The organization-developer must have in its staff specialists with experience of work on construction sites, who know the technology of construction production. When using lifting structures, it is necessary to have industrial safety certification protocols for specialists. For development technical solutions accepted in the PPR, often the customer requires the developer's membership in the SRO.

The General Contractor may prescribe in the contract with the Subcontractor the obligation to develop for him. In this case, based on the volumes performed by the Subcontractor, a decision is made to develop PPR and / or separate technological maps for an already existing project for the production of work on the object.

Who approves the project for the production of PPR works

PPR is approved by the technical manager of the contractor ( Chief Engineer, technical director, deputy director for construction, or others) performing these works. Thus, taking all the prescribed measures for execution.
The project for the production of work is submitted for approval in a completely finished form with all attachments and signatures. After signing, the seal of the organization is put and the project is submitted for approval to interested parties involved in the construction (Customer Departments, Customer's Construction Control, owners of utilities, etc.).

Who approves the project for the production of PPR works

The approval of the PPR is carried out by the Contractor in the following sequence:

Customer services: Department of capital construction OKS, HSE, fire department, power engineering, department of the chief mechanic and other representatives depending on the structure of the company;
OATI (for Moscow), GATI (for St. Petersburg) and similar organizations, taking into account the regulatory legal acts of the Government of the Russian Federation in the territory of the work;
Owners of buildings and structures located near the projected facility;
Organizations-owners of intersected underground and overground communications (water supply, communication cables, gas pipeline, heating, etc.) when crossing them;
By the owners of the machines and mechanisms used;
In some cases, representatives of Rostekhnadzor.

To agree on a project for the production of work, it includes a separate sheet with columns: position, full name, signature and comments. On the basis of the signatures on the title page, the signature of the technical managers of the coordinating persons is put.

Who signs the work production project

The signing of the PPR is carried out by specialists who have developed separate sections. The framed table of contents contains the signatures of the developer, reviewer and technical manager. Technological maps are signed by the compilers: Quality Control Department for welding by the chief welder or welding engineer, TC for quality control and incoming control materials - by a construction control engineer, etc.

How to compose

You can draw up a PPR on your own by shoveling a bunch of regulatory documents. But it takes a lot of time and effort of specialists. Its design can be entrusted to developers - specialized companies.
In order to start compiling it, you first need to study the MDS and then the composition of the future PPR will be clear. After you have studied it, you need to start studying the entire scientific and technical documentation for the work performed, for example, a joint venture for concrete work, a joint venture for the installation of building structures and take only the necessary information and include it in the document. Take standard projects as a basis it is possible, but now it is very difficult to find relevant ones containing new requirements for labor protection and construction technologies. Everything typical has long been outdated.

Alteration

In the process of manufacturing construction and installation work, in most cases, it becomes necessary to make changes to the already developed PPR. This may be facilitated by: underground utilities not specified in the construction plan were discovered; equipment that was supposed to be used is difficult to find and is similar, but it is necessary to change the technology (for example, a concrete pump cannot deliver to a certain height, it is necessary to supply concrete with a bucket to the floors); changes in the working draft, etc. Only the developer can make changes and in agreement with the persons who signed it. Those. after that, it is necessary to go through the procedure of its approval again.
