What are the items of factory machine maintenance

A, equipment maintenance

Through wiping, cleaning, lubrication, adjustment and other general methods of care for the equipment to maintain and protect the performance and technical condition of the equipment, known as equipment maintenance. Equipment maintenance requirements are mainly four:

(1) cleaning equipment inside and outside neat, each sliding surface, screws, rack, gear box, oil holes and other parts of the oil, no oil, no oil leakage, no air leakage, the equipment around the chips, debris, dirt should be cleaned up;

(2) neat ? Tools, accessories, workpieces (products) to be placed neatly, pipelines, lines should be organized;

(3) good lubrication, timely refueling or oil change, continuous refueling, no dry friction phenomenon, the oil pressure is normal, oil spots, smooth oil surface, oil to meet the requirements of the oil quality, oil guns, oil cups, felts are clean;

(4) comply with the safety regulations, do not overload the use of equipment, equipment safety Protection devices are complete and reliable, and unsafe factors are eliminated in a timely manner.

Equipment maintenance content generally includes routine maintenance, regular maintenance, regular inspection and precision inspection, equipment lubrication and cooling system maintenance is also an important element of equipment maintenance.

The routine maintenance of equipment is the basic work of equipment maintenance, must be institutionalized and standardized. Regular maintenance of equipment, the development of work quotas and material consumption quotas, and assessed according to the quota, the maintenance of equipment into the workshop contract responsibility system assessment.

Periodic inspection of equipment is a planned preventive inspection, the means of inspection in addition to human senses, there are a certain number of inspection tools and instruments, according to the periodic inspection card, periodic inspection is also known as periodic inspection. Check the accuracy of mechanical equipment to determine the actual accuracy of the equipment. Equipment maintenance should be carried out in accordance with the maintenance program.

Equipment maintenance regulations are the requirements and regulations on the daily maintenance aspects of the equipment, adhere to the implementation of equipment maintenance regulations, can extend the service life of the equipment, to ensure a safe and comfortable working environment. Its main content should include:

(1) equipment should be neat, clean, strong, lubrication, corrosion, safety and other work content, work methods, the use of tools and materials, standards and precautions.

(2) Daily inspection and maintenance and regular inspection of the parts, methods and standards;

(3) check and assess the degree of maintenance of equipment by operators, such as the content and methods.

Two, the three-tier maintenance system of equipment

The three-tier maintenance system is in the summary of the former Soviet Union since the mid-1960s in China on the basis of the practice of pre-maintenance system to gradually improve and develop a maintenance system, which reflects the shift in the center of gravity of the equipment. nt maintenance management in our country from maintenance to maintenance, reflecting the progress of China's equipment maintenance management. Preventive maintenance management policy is clearer.

Three-tier maintenance system includes: routine maintenance of equipment, first level maintenance and second level maintenance. The three-tier maintenance system is based on the operator of the equipment for the main guarantee, warranty and mandatory maintenance system. The three-tier maintenance system is to rely on the masses, give full play to the enthusiasm of the masses, the implementation of group management group repair, specializing in the combination of groups, to improve the maintenance of equipment and effective methods.

(a) the daily maintenance of equipment

The daily maintenance of equipment, generally have daily and weekly maintenance, also known as daily and weekly routine maintenance.

1. Day routine insurance

Daily routine insurance by the equipment operator workers on duty, seriously do four things before the shift, five attention in the class and four things after the shift.

(1) The first four things are digesting drawings and checking shift records. Wipe, lubricate and grease the equipment as specified. Checks position of handles and manually operated parts for correctness and flexibility, and safety devices for reliability. Runs at low speeds to check for proper transmission and smooth lubrication and cooling.

(2) Five notes in the shift ? Pay attention to the running sound, equipment temperature, pressure, liquid level, electrical, hydraulic, pneumatic system, instrument signal, safety insurance is normal.

(3) Four is to turn off the switch after shutting down the machine, put all the handles in the zero position. Remove iron filings, dirt, wipe oil stains on rails and sliding surfaces of equipment and fill with oil. Cleans work space and arranges accessories and tools. Fills out records for inverted shifts and operator's desk for shift work.

2. Weekly routine maintenance

Weekly routine maintenance is carried out by equipment operators at the end of each week, and the maintenance time is 2h for general equipment and 4h for fine, large and rare equipment.

(1) Appearance ? Wipe clean the equipment rails, all transmission parts and exposed parts, clean the workplace. To achieve internal and external cleanliness without dead ends, no corrosion, the surrounding environment is neat.

(2) Check the technical status of each part, tighten the loose parts, adjust the fit gap. Check the interlocking devices and safety devices. Transmission sound is normal, safe and reliable.

(3) Hydraulic lubrication ? Clean the oil line, dust felt, oil filter, oil tank add oil or oil change. Check the hydraulic system to achieve clean oil, smooth oil circuit, no leakage, no research injury.

(4) Electrical system ? Wipe the surface of the motor, snake skin tube, check the insulation, grounding, to achieve complete, clean and reliable.

(2) the first level of maintenance

The first level of maintenance is based on the operation of the workers, maintenance workers to assist, according to the plan of the local disassembly and inspection of the equipment, cleaning of the prescribed parts, dredge the oil circuit, pipeline, replacement or cleaning of oil line, felt, oil filter, adjusting the equipment parts of the fit gap, tighten the various parts of the equipment.

The first level of maintenance time is 4-8 hours. Upon completion of the first level of maintenance, records shall be made and attention shall be given to defects not removed. The shop mechanic should organize an inspection and acceptance. The scope of the guarantee should be that all companies are using the equipment, and critical equipment should be strictly enforced.

The main purpose of the first guarantee is to reduce the wear and tear of the equipment, to eliminate hidden problems, to prolong the service life of the equipment, and to provide the equipment to complete the production tasks in the next guarantee period.

(iii) Second level maintenance

The second level maintenance is mainly performed by maintenance workers with the participation of operation workers. The equipment maintenance program includes secondary maintenance. The equipment is partially disassembled, inspected and repaired, worn parts are replaced or repaired, and electrical parts are cleaned, replaced and repaired so that the technical condition of the equipment fully meets the requirements of the required equipment integrity standards. The two levels of maintenance last approximately 7 days.

After the completion of the second level of maintenance, maintenance workers should fill in the overhaul records in detail, acceptance by the workshop mechanic and operator, acceptance sheet to the equipment power section archives. The main purpose of the second guarantee is to make the equipment to reach the standard of perfection, improve and consolidate the rate of equipment perfection, and extend the overhaul cycle.

The implementation of the "three-tier maintenance system", must make the operator of the equipment to do "three good", "four will", "four requirements " and comply with the "five disciplines". The three-tier maintenance system highlights the maintenance of equipment management and planned maintenance work in the status of the operators of the workers "three good", "four will" requirements more specific, improve the operators to maintain the knowledge and skills of equipment.

Three-tier maintenance system breaks through the relevant provisions of the former Soviet Union plan to repair system, improve the plan to repair some of the shortcomings of the system, more practical. In the implementation of the three-tier maintenance system also learned and absorbed some of the practices of the army management of weapons, and emphasized the group management and group repair.

Three-tier maintenance system in China's enterprises have achieved good results and experience. The implementation of the three-tier maintenance system effectively improves the equipment integrity rate, reduces the accident rate of equipment, extends the equipment maintenance cycle, reduces the cost of equipment overhaul, and achieves good technical and economic results.

Three, fine, large, rare equipment use and maintenance requirements

(a) four fixed work

(1) fixed use of personnel. According to the fixed person fixed machine system, fine, large, dilute equipment operators should choose the type of work in a strong sense of responsibility, high level of skill and practical experience, and as far as possible to maintain a relatively long period of relative stability;

(2) fixed maintenance personnel. Fine, large, dilute equipment more enterprises, according to the conditions of the enterprise, can organize fine, large, dilute equipment professional maintenance or repair group, specifically responsible for the fine, large, dilute equipment inspection, precision adjustment, maintenance, repair;

(3) the operating procedures. Precision, large, rare equipment should be divided into models and prepare operating procedures, to show and strictly enforced;

(4) fixed spare parts. According to the role of various fine, large and rare equipment in the production of enterprises and the source of spare parts, to determine the reserve quota, and prioritize the solution.

(2) Precision equipment use and maintenance requirements

(1) must be strictly in accordance with the provisions of the instructions for the installation of equipment;

(2) special requirements for the environment of the equipment (constant temperature and humidity, shockproof, dustproof) enterprises should take appropriate measures to ensure that the accuracy of the equipment performance:

(3) equipment in the daily maintenance of the maintenance of the parts and components are not allowed to be dismantled, found abnormalities immediately stop, do not allow parts to be removed, and do not permit the use of equipment. Abnormalities found immediately stop, not allowed to operate with disease;

(4) Strict implementation of the cutting specifications specified in the equipment manual, only allowed to parts finishing according to the direct use. The machining allowance should be as small as possible. Processing castings, the blank surface should be pre-blasted or painted;

(5) non-working hours should be added shroud, long stop, should be regularly wiped, lubrication, idling;

(6) accessories and special tools should be a special cabinet shelves, to keep clean, to prevent research injuries, and shall not be lent.

Four, the use of power equipment maintenance requirements

Power equipment is the key equipment in the enterprise, in the operation of high temperature, high pressure, flammable, toxic and other hazardous factors, is to ensure the safety of the production of key parts, in order to achieve a safe and continuous and stable supply of production of kinetic energy, the use of power equipment maintenance should be a special requirement:

(1) the operation of the operator And report to the superior in time;

(5) Ensure that all kinds of indicating instruments and safety devices are sensitive and accurate, and regularly calibrated. Standby equipment is complete and reliable;

(6) Power equipment shall not be operated with disease, and any malfunction must be eliminated in time;

(7) Preventive tests and seasonal inspections are carried out on a regular basis;

(8) Safety education is often given to the staff on duty, and the safety and security system is strictly enforced.

V. Regional maintenance of equipment

Regional maintenance of equipment is also known as the maintenance contractor mechanism. Maintenance workers to undertake a certain production area of equipment maintenance, work with the production and management staff to do a good job of routine maintenance, inspection, regular maintenance, scheduled maintenance and troubleshooting, and is responsible for equipment to complete in the jurisdiction of the machine rate, failure rate and other assessment indicators.

Regional maintenance responsibility system is to strengthen the maintenance of equipment for production services, mobilize the enthusiasm of maintenance workers and make production workers take the initiative to care about equipment maintenance and repair work in a good form.

Equipment professional maintenance of the main form of organization is the regional maintenance group. Regional maintenance group is fully responsible for the production of regional equipment maintenance and emergency repair work, its tasks are:

(1) responsible for the maintenance and repair of equipment in the region, to ensure the completion of the equipment completion rate, failure downtime rate and other indicators;

(2) the implementation of the equipment regular inspection and regional inspection system, guidance and supervision of operators to do a good job of routine maintenance and regular maintenance work;

(3) the maintenance of equipment, equipment and equipment, equipment and equipment maintenance and repair work;

(4) the production of equipment, equipment and equipment maintenance and emergency repair work, the production of equipment and equipment maintenance, equipment and equipment maintenance and emergency repair work.

(3) Participate in equipment condition census, accuracy check, adjustment, leakage cure, fault analysis and condition monitoring under the guidance of workshop mechanic.

The advantages of this type of equipment maintenance organization are that it is highly mobile when emergency repairs are completed, thus minimizing equipment repair interruption time, and that on-duty fitters can complete preventive operations and participate in scheduled repairs when no one else is able to make emergency repairs.

Division of the equipment maintenance area should take into account the distribution of production equipment, the state of the equipment, technical complexity, production needs and maintenance of the skill level of the fitter. According to the above factors, workshop equipment can be divided into several regions, regional maintenance group can also be divided according to the type of equipment. Production line equipment should be divided into maintenance areas by line.

Regional maintenance teams should develop a program of regular and precise inspections and set regular inspection times for each shift. To prevent these efforts from interfering with production, scheduled inspections of equipment shall be scheduled on non-work days in the plant and routine inspections shall be scheduled each shift during the lunch break of production workers.

Sixth, improve the level of equipment maintenance measures

In order to improve the level of equipment maintenance should be made to maintain the work of the basic three, that is, standardization, process, institutionalization.

Normalization is to make the maintenance of the content of the unity, which parts of the cleaning, which parts should be adjusted, which device should be checked, according to the situation of each enterprise according to the objective law to be unified considerations and regulations.

The process is based on different equipment to develop the maintenance process, according to the regulations for maintenance.

Institutionalization is based on different working conditions of different equipment, different maintenance cycles and maintenance time, and strictly enforced.

The regular maintenance work, to develop a quota of working hours and material consumption quota and to be assessed according to the quota.

Equipment maintenance work should be combined with the enterprise production economic contract responsibility system for assessment. At the same time, the enterprise should also mobilize the masses to carry out a combination of specialized groups of equipment maintenance work, self-inspection, mutual inspection, to carry out equipment inspection

Ensure that the facilities, equipment and premises in good condition, in order to improve the quality of service needs.

(a), equipment and facilities classification according to the function of various types of equipment and facilities, use, importance and other factors in its implementation of the classification and management, divided into A, B, C three categories, such as:

Category A: monitoring system equipment, the power distribution room screen cabinets, life pumps, fire pumps, fire alarm systems, elevators and other.

Category B: exhaust equipment, water tank (pool), fire-fighting equipment, sewage pumps and other.

Category C: housing body lighting facilities, indoor and outdoor sockets, various lamps and lanterns, faucets, drainage facilities, roads and others.

Equipment maintenance for the service life of the equipment is exceptionally important and for the use of staff safety is also closely related to the frequent maintenance of the equipment will not only facilitate production, but also to ensure the safety of employees.

This for the factory not only saves money but also saves manpower and material resources, the staff for the enterprise's satisfaction will also rise, often repair and maintenance will also be exempted from some of the relevant departments to check the unnecessary trouble.
