Equipment maintenance and upkeep includes:
Daily maintenance, Level 1 maintenance, and Level 2 maintenance. The Level 3 maintenance system is a mandatory maintenance system primarily based on operator responsibility, emphasizing both maintenance and repair. The Level 3 maintenance system relies on the masses, fully utilizing their enthusiasm, implementing group management and repair, and combining specialized and mass efforts to effectively maintain and upkeep equipment.
Daily Maintenance and Upkeep
Daily maintenance and upkeep generally includes daily maintenance and weekly maintenance, also known as routine maintenance and weekly routine maintenance.
Routine Maintenance
Routine maintenance is performed by the equipment operator during their shift, diligently fulfilling four tasks before the shift, five points to note during the shift, and four tasks after the shift.
(1) Four tasks before the shift: Thoroughly review drawings and documents, and check handover records. Wipe down the equipment and lubricate as required. Check the position of handles and manual operating parts for correctness and flexibility, and the reliability of safety devices. Run the equipment at low speed to check if the transmission is normal and if lubrication and cooling are unobstructed.
(2) During the shift, pay attention to the operating sounds, temperature, pressure, liquid level, electrical, hydraulic, and pneumatic systems of the equipment, instrument signals, and whether safety fuses are functioning properly.
(3) After the shift, do the following four things: turn off the switches, put all handles to the zero position, remove iron filings and dirt, wipe the oil stains off the equipment guide rails and sliding surfaces, and add oil. Clean the work area and organize accessories and tools. Fill out the shift handover record and operating time record, and complete the shift handover procedures.
Weekly Maintenance
Weekly maintenance is performed by the equipment operator at the end of each week. The maintenance time is: 2 hours for general equipment, and 4 hours for precision, large, and rare equipment.
(1) External Inspection: Wipe the equipment guide rails, all transmission parts, and exposed parts clean, and clean the work area. Achieve a clean interior and exterior with no dead corners, no rust, and a tidy surrounding environment.
(2) Operation and Transmission: Check the technical condition of each part, tighten loose parts, and adjust the fit clearance. Check the interlocks and safety devices. Achieve normal transmission sounds and reliable safety.
(3) Clean the hydraulic lubrication lines, dustproof felt, and oil filter; add or change the oil in the tank. Inspect the hydraulic system to ensure the oil is clean, the oil lines are unobstructed, there are no leaks, and there are no scratches.
(4) For the electrical system, wipe the surface of the motor and flexible conduit; check the insulation and grounding to ensure they are intact, clean, and reliable.
