(2) The parts, methods and standards of daily inspection, maintenance and regular inspection of Rizhao machinery;

(3) Check and evaluate the contents and methods of operator's maintenance equipment and glass machinery.

Second, the equipment three-level maintenance system

Three-level maintenance system is a kind of maintenance and repair system that started in the mid-1960s in China. It is gradually improved and developed on the basis of summarizing the practice of the pre-repair system of the joint plan of mechanical seals in the former Soviet Union. It reflects the change of the focus of equipment maintenance management in China from repair to maintenance, and reflects the progress of equipment maintenance management in China and the clearer maintenance management policy of prevention first. The capacity of conveying machinery in the three-level maintenance system includes daily maintenance, first-level maintenance and second-level maintenance of equipment. Three-level maintenance system is a compulsory maintenance system that takes the operator as the center, guarantees equipment and enriches man-machine system. The three-level maintenance system is an effective way to rely on the masses, give play to their enthusiasm, implement group management and group maintenance, and combine special groups to do a good job in equipment and agricultural machinery maintenance.

(1) Daily maintenance of equipment

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

1, routine insurance

The daily work shall be carried out by the equipment operators on duty, and the four things before class, five things to pay attention to in class and four things after class in mechanical design and manufacture shall be done carefully.

(1) Arrange the pattern data of four things before the shift change, and check the shift change records. Wiping shall be prepared by the mechanical processing plant, and lubricated and oiled as required. Check whether the handle position and manual operation position are correct and flexible and whether the safety device is reliable. Check whether the transmission mechanism is normal and whether the lubrication and cooling are smooth when running at low speed.

(2) Pay attention to whether the operating sound, equipment temperature, pressure, liquid level, electro-hydraulic mechanical gas, hydraulic pneumatic system, instrument signal and safety insurance are normal.

(3) Turn off the four-object switch after work, and all the handle mechanical technologies will return to zero. Remove iron filings and dirt, clean the oil stains on the guide rail surface and sliding surface of the equipment, and refuel. Clean up the work site, arrange accessories and tools. Fill in Tianjin machinery handover record and operation time record, and handle handover procedures.

2. Weekly guarantee

Weekly box maintenance is carried out by equipment operators in carton machinery every weekend. The maintenance time is 2 hours for general equipment and 4 hours for fine, large and thin equipment.

(1) Externally clean the guide rails of equipment, components of various transmission chemical machinery and exposed parts, and clean the work site. Achieve cleanliness inside and outside, no dead ends and no rust, and the surrounding environment is clean and tidy.

(2) Control and drive the coal mine machinery to check the technical conditions of all parts, tighten loose parts and adjust the fit clearance. Check interlocking and safety devices. Transmission sound is normal, safe and reliable.

(3) Hydraulic lubrication cleans the oil circuit, dust cover and oil filter, and adds oil or changes oil in the oil tank. Check the hydraulic system to ensure that the oil is clean, the machinery is clean, the oil circuit is smooth, there is no leakage and no wear.

(4) The electrical system should wipe the surface of the motor and the snake skin tube, check the insulation and grounding, and the cleaning machine should be complete, clean and reliable.

(2) Primary maintenance

The first-level maintenance is given priority to with operators, supplemented by maintenance workers. According to the mechanical drawing plan, partially disassemble and inspect the equipment, clean the designated parts, dredge the oil circuit and pipeline, replace or clean the oil circuit, linoleum and oil filter, adjust the fit clearance of each part of the equipment, and fasten each part of the equipment. The first-class curing time is 4-8 hours. After the first-level maintenance is completed, records shall be made and the uncleared mechanical manufacturing and automation defects shall be indicated, and the workshop mechanic shall organize the acceptance. The scope of land protection should be all the equipment in use of the enterprise, and the key equipment should be strictly implemented. The main purpose of the first warranty is to reduce the wear and tear of mechanical drawing software and equipment, eliminate hidden dangers, prolong the service life of equipment and provide guarantee for the completion of production tasks until the next first warranty period.

(III) Secondary maintenance

Secondary maintenance is mainly completed by maintenance workers and operators. Secondary maintenance is included in the maintenance plan of Taiyuan Railway Machinery School, and the equipment is partially disassembled, inspected and repaired, worn parts are replaced or repaired, and electrical components are cleaned and replaced, so that the mechanical cad of the technical condition of the equipment completely meets the requirements of the specified equipment integrity standards. The second maintenance takes about 7 days.

After the second guarantee is completed, the repairman should fill in the maintenance records of the machinery industry in detail, which will be accepted by the workshop mechanics and operators, and the acceptance sheet will be submitted to the equipment power department for filing. The main purpose of the second maintenance site is to make the equipment reach the intact standard, improve and consolidate the intact rate of the equipment, and extend the overhaul period.

To implement the "three-level maintenance system", operators must achieve "three excellent", "four skills" and "four essentials" and abide by the "five major disciplines" of equipment.

The three-level maintenance system highlights the position of maintenance in equipment management and planned maintenance, which makes the requirements of "three good" and "four good" for operators more specific and improves the knowledge and skills of operators in maintaining equipment. The three-level maintenance system of Shenyang Railway Machinery School has broken through the relevant provisions of the planned pre-repair system of the former Soviet Union, improved some shortcomings in the planned pre-repair system, and is more practical. When implementing the three-level maintenance system, the machinery and equipment factory also learned and absorbed some weapons management practices, emphasizing group management and group maintenance. The three-level maintenance system has achieved good results and experience in China enterprises. The implementation of the three-level maintenance system of mechanical drawing has effectively improved the intact rate of enterprise equipment, reduced the accident rate of equipment, extended the overhaul period of equipment and reduced the overhaul cost of coal mine machinery, and achieved good technical and economic effects.

Three, fine, large and fine four work equipment use and maintenance requirements.

(1) Specify the user. According to the system of "man-to-man, machine-to-machine", the operators of fine, large and rare equipment should choose those who are responsible for mechanical equipment, with high technical level and rich practical experience, and keep relatively stable as long as possible;

(2) Fixed maintenance personnel.

Verb (abbreviation of verb) regional maintenance of equipment

The regional maintenance of equipment is also called the maintenance of complete sets of coal mine machinery. The repairman undertakes the maintenance of equipment in a production area in Chinese mainland, and works with production operators to do daily maintenance, patrol inspection, regular maintenance of basic mechanical knowledge, planned maintenance, troubleshooting, etc., and is responsible for completing the assessment indicators such as equipment integrity rate and failure rate in mainland China. The regional maintenance responsibility system of construction machinery parts is a good form to strengthen the maintenance of production equipment, mobilize the enthusiasm of maintenance workers and let production workers take the initiative to care about equipment maintenance.

The main organization form of equipment professional maintenance is regional maintenance group. The regional maintenance team is fully responsible for equipment maintenance and downloading the mechanical design manual for emergency maintenance in the production area. Its tasks are:

(1) Responsible for the maintenance and repair of equipment in this area; Ensure the completion of equipment integrity rate and other indicators; Mechanical rate caused by failure in Suzhou; Wait a minute.

(2) Conscientiously implement the system of regular spot inspection and regional inspection of equipment, and guide and urge operators to do regular maintenance of daily maintenance and mechanical maintenance;

(3) Under the guidance of the workshop mechanic, participate in equipment condition investigation, precision inspection, adjustment and leakage treatment, and carry out analysis and condition monitoring of China Machinery Industry Federation.

As an organizational form of equipment maintenance, the regional maintenance team has the advantages that it has a highly mobile China construction machinery business network when completing emergency maintenance, so that the equipment maintenance downtime zui can be very short, and the locksmith on duty can complete various preventive operations and participate in planned maintenance without being called.

The division of metallurgical machinery and equipment maintenance area should consider the distribution of production equipment, equipment status, technical complexity, production needs and the technical level of fitter repair. Workshop equipment can be divided into several areas according to the above factors, and regional maintenance groups can also be divided according to equipment types. The equipment on the assembly line should be divided into maintenance areas by sand diggers.

The regional maintenance team shall formulate a plan for regular inspection and precision inspection, and specify the mechanical technology time for routine inspection of each shift of equipment. In order to make these work not affect the production, the planned inspection of the equipment should be arranged in the non-working days of the factory, and the routine inspection of each shift should be arranged during the lunch break of the mechanical technology production workers.

Measures to improve equipment maintenance level with intransitive verbs

In order to improve the level of equipment maintenance, the hydraulic machinery of maintenance workers should be basically standardized, technical and institutionalized.

Standardization is to unify the maintenance content, which parts need to be cleaned, which lifting machinery parts need to be adjusted and which devices need to be inspected, which should be considered and stipulated according to objective laws and the situation of each enterprise.

Technicalization is to formulate various maintenance procedures according to different equipment of plastic machinery and carry out maintenance according to the procedures.

Institutionalization is to stipulate the maintenance cycle and time of mechanical watches according to the different working conditions of different equipment, and strictly implement them.

Regular maintenance work needs to formulate man-hour quota and material consumption quota, and conduct assessment according to the quota of chemical machinery. Equipment maintenance work should be assessed in combination with the enterprise production economic contract responsibility system. At the same time, enterprises should also mobilize the masses to carry out equipment maintenance work combining professional mechanical watches, conduct self-inspection, mutual inspection and major equipment inspection.
