Thread Content

1. Contents of the “three-level maintenance system”. 1. Daily maintenance: Operators should carefully check the equipment before and after work, wipe all parts and add lubricating oil to keep the equipment neat, clean, lubricated and safe. And carefully keep inspection records and shift handover records. If an equipment failure occurs in the class, report the failure in a timely manner, participate in troubleshooting, record the time and cause of the failure, and confirm the repair effect. 2. First-level maintenance: Operators will be the main ones, and maintenance workers will provide guidance to carry out partial disassembly and inspection of the equipment as planned, and clean the specified parts. ； Dredge oil lines and pipelines, replace or clean oil lines, linoleum, and oil filters ； Adjust the matching clearance of various parts of the equipment and tighten all parts of the equipment. 　　3. Secondary maintenance: Focusing on maintenance, the equipment is included in the equipment maintenance plan to partially disassemble, inspect and repair the equipment. ； Replace or repair worn parts, clean and change oil ； Check and repair electrical parts ； Local recovery accuracy meets the minimum requirements for machined parts. 2. The "Three Goods" and "Four Meetings" are implemented in the "three-level maintenance system". Operators must be able to meet the requirements of the "Three Goods" and "Four Meetings" for the equipment.: 1. Contents of “Three Good Things”: (1) Take good care of: Consciously abide by the system of fixed personnel and fixed machines, use equipment with operating certificates, and do not use other people's equipment indiscriminately. ； Take good care of tools and accessories so that they are not lost or damaged and placed neatly ； Complete and easy-to-use safety protection devices ； The wiring and pipes are complete. (2) Use it well: The equipment operates without problems, is not used overloaded, does not use large machines for small purposes, and does not use fine machines for rough use. ； Comply with operating procedures and maintenance procedures ； Take good care of the equipment to prevent accidents. (3) Repair: Scheduled maintenance time ； Downtime for repair ； Actively cooperate with maintenance workers to participate in secondary maintenance of equipment, major and medium repairs, and post-completion acceptance test runs. 2. The contents of the "Four Meetings" (1) will be used: Be familiar with the equipment structure, master the technical performance and operation methods of the equipment ； Understand processing techniques and use equipment correctly. (2) Know how to maintain: Correctly refuel and change oil according to the lubrication chart, keep the oil line smooth, and keep the oil line, linoleum, and oil filter clean. ； Clean carefully and keep the inside and outside of the equipment clean. There is no grease or dirt. The paint will show its true color and the iron will show the light. ； Carry out first-level maintenance work according to regulations. (3) Will check: Understand equipment accuracy standards, be able to check accuracy inspection items related to processing technology, and make appropriate adjustments ； Safety guards and safety devices will be checked. (4) Will troubleshoot: Able to detect abnormal conditions of the equipment through normal sound, temperature and operating conditions, determine the location and cause of the abnormal conditions, and take timely measures to eliminate faults ； When an accident occurs, participate in analysis, identify the cause of the accident, learn lessons, and take preventive measures.
