In order to ensure the safe operation of equipment, equipment maintenance using preventive maintenance and planned maintenance. According to the company's production site equipment types are divided into: power supply and water supply steam energy equipment, refrigeration, air conditioning and ventilation equipment, mold processing equipment, hardware production equipment, printing equipment, plastic products equipment, transportation equipment, communication and monitoring equipment; according to the operation of the equipment use, the law of wear and tear of the equipment and failure of the law, the development of equipment repair and maintenance and repair methods.
Equipment maintenance classification and operation content is based on the actual use of technical changes in the situation; the structure of the equipment; the use of the conditions; environmental conditions and so on to determine. Is based on the law of wear and tear of parts, the law of aging, the degree of similar items are concentrated in the normal wear and tear, aging, will reach the use of the period of time before the maintenance, to keep the equipment neat and clean, to find and eliminate the potential for failure, to prevent early damage to the equipment, to achieve the purpose of maintaining the normal operation of the equipment.
Equipment maintenance work, based on the size of the workload and the degree of difficulty, divided into routine maintenance, one, two, three levels of maintenance.
1, routine maintenance
Operating workers must be carried out every shift of equipment maintenance work, which includes: cleaning, refueling, adjusting, replacing individual parts, checking the lubrication, noise, oil leakage, leakage safety and damage. Daily maintenance with the daily inspection and inspection, is a way to maintain the equipment without occupying the working hours alone. 2, the maintenance of equipment
The maintenance of equipment is an important part of the rational use of equipment, must be replaced by a mandatory maintenance system with those who are bad with the repair, repair instead of insurance, to carry out frequent demolition of the practice.
Equipment repair and maintenance is the main idea under the guidance of prevention, the equipment maintenance operations according to the length of the cycle were organized together, graded regular implementation of the regular maintenance of equipment is divided into: a level of maintenance, secondary maintenance, three-level maintenance. ○1 level of maintenance
Periodic inspection-based, supplemented by maintenance overhaul of a form of indirect preventive maintenance. Its main work is: check, clean, adjust the automatic line drive mechanism, conveyor belt parts; check the oil pump, dredge the oil circuit, check the oil tank oil quality, oil quantity; remove the activity surface burrs; check, adjust the indicator and safety guards; found faults and anomalies, to be excluded, and exclude leakage phenomenon.
Equipment by the first level of maintenance requirements to achieve: clean and bright appearance; smooth oil circuit, oil window clear bright; flexible operation, normal operation; electrical safety protection, indicating instrumentation is complete and reliable. Maintenance personnel should be the main content of maintenance, maintenance process found and eliminated hidden dangers, abnormalities, test run results, production parts and components precision, operational performance, as well as the existence of problems to make a record. The first level of maintenance is based on the operator, professional maintenance personnel (mechanic clampers, electricians) to cooperate and guide. ○2 secondary maintenance
is to maintain the technical condition of the equipment is mainly in the form of overhaul, the workload of the second level of maintenance between the repair and repair part of the work, but also to complete a part of the repair, mainly for the wear and tear of the equipment and damage to vulnerable parts for repair or replacement. Secondary maintenance to complete all the work of the first level of maintenance, but also requires all lubrication parts of the cleaning, combined with the oil change cycle to check the lubricant quality, cleaning and oil change. Check the dynamic technical condition of the equipment and the main precision (noise, vibration, temperature, oil pressure, corrugation, surface roughness, etc.), adjust the installation level, replacement or repair of parts, scrape and study the wear and tear of the movable guide surface, repair and adjust the precision of the deteriorated parts, calibrate the instrumentation, repair the safety devices, cleaning or replacement of motor bearings, etc.. After the second level of maintenance requires precision and performance to meet the process requirements, no oil leakage, gas leakage, leakage phenomenon, sound, vibration, pressure, temperature rise and so on in line with the standard. Before and after the second level of maintenance should be carried out before and after the equipment for dynamic and static technical condition determination, and carefully make maintenance records. The second level of maintenance to professional maintenance personnel (mechanic clampers, electricians) as the main, the operator to participate.
○
3 three-level maintenance In order to standardize the three-level maintenance of equipment, according to the wear and tear of equipment parts, performance, precision deterioration and the likelihood of failure, etc., the use of the production off-season, the Ministry of Equipment, based on the use of equipment to develop the maintenance of equipment maintenance and repair of the content and plan, replacement of spare parts schedule and maintenance cost estimates, reported to the General Manager's Office, Finance Department review and summarize the general manager approved by the implementation of the maintenance content, including all the contents of the second level of maintenance and the need to shut down production and overhaul of the equipment. Equipment repair and maintenance of all the contents of the record reported to the company's equipment department for the record and archives.
Part II: safety management and maintenance of special equipment and maintenance plan
A definition of special equipment
Special equipment refers to the life safety, the danger of boilers, pressure vessels (including ammonia refrigeration compressors, cylinders, heat exchange equipment), pressure piping, elevators, lifting machinery and facilities.
Two, clear safety management of special equipment responsible
1, clear safety management responsible. Safety management should be responsible for the company's special equipment or key equipment is fully responsible for (the person in charge of safety production must be the main person in charge of the Department of equipment and familiar with the safe operation of equipment).
2, the operator must know how to operate, the possible safety accidents have foresight. Special equipment operators must, in principle, obtain the national unified format of the certificate can be on duty. Strictly prohibit untrained personnel on duty.
Three, special equipment safety management system
(a) the development of special equipment safety regulations and operating procedures
The development of the unit's special equipment safety regulations. Including: the person in charge of production safety duties, special equipment full-time part-time managers duties, special equipment operators duties; boiler room safety management duties, machine room safety management duties, special equipment maintenance management system, special equipment regular self-inspection and rectification of hidden problems system, special equipment inspection system. According to the types of special equipment and the requirements of regulations and safety specifications,
preparation of safety operation procedures for each position. Special equipment management system, accountability, operating procedures posted to the appropriate departments, jobs, special equipment use
Four, special equipment maintenance system
1, special equipment safety management personnel should keep abreast of the implementation of maintenance plans, and is responsible for supervision and inspection, so that the special equipment maintenance system, standardization. Operators should do Taiwan equipment, lines, valves, only instrumentation is responsible for the elimination of the phenomenon of no one is responsible for.
2, in strict accordance with the operating procedures and the prescribed steps. Serious preparation before the start of the equipment, the start of repeated checks, stopping properly handled, not over-temperature, not over-pressure, not overloaded, are not allowed to leave their posts in the operation of the equipment.
3, the post within the scope of the equipment to strictly implement the inspection system, and effectively do the "four diligence (diligently check, diligently observe, diligently contact, diligently regulate)". When the equipment failure, maintenance personnel should quickly go to the scene, according to the failure phenomenon, analyze and judge the cause of the failure, and for the cause of the failure of the implementation of effective maintenance processing. When the fault can not be immediately eliminated, to record in detail, and promptly reported.
4, the operator of the equipment used to do "four understand, three will" (understand the structure, understand the performance, understand the regulations, understand the use, will use, will maintain, will troubleshooting), strict implementation of the post's operating procedures, found that the equipment is not running normally, overdue inspection, safety devices do not meet the requirements should be reported immediately. The company's products and services are also available on the market.
