EQUIPMENT MANAGEMENT AND MAINTENANCE

oil pipe, oil cylinder, and accessories should be free of leaks, abnormal temperature rise at the lubrication part, oil pipe
and the detection and metering instruments should display leakage, oil and gas evaporation, etc., immediately shut down
normally. Sixth, check the sensitivity and reliability of electrical the machine for inspection and handling. Fourthly, regularly
safety protection devices such as emergency stop switches, check whether the pressure and temperature of the hydraulic
alarms, buzzers (indication signals), and safety interlock system are within the specified range. In case of oil circuit
devices, and adjust or repair them if necessary. Seventh, check blockage, pipeline leakage, oil temperature exceeding the
the sensitivity, effectiveness, and accuracy of electrical limit standard, oil and gas evaporation, etc., immediately shut down
devices such as travel switches and proximity switches, and the machine for inspection and handling. Fifthly, regularly
adjust or repair them if necessary. Eighth, check the "zero drift" check whether the pressure, flow rate, and temperature of
of detection devices, metering devices, or weighing systems, and the temperature control system meet the process technical
calibrate them if necessary. Ninth, verify the equipment operating requirements and whether there are any leaks. Sixthly,
parameters and production process parameters, and adjust them regularly check the lubrication condition of manual lubrication
if necessary to meet production needs. Tenth, conduct a no-load parts and timely replenish lubricating oil and grease. Seventhly,
test run before load operation to check for abnormalities such as inspect metal structural parts, components, connectors, etc.

according to the equipment spot inspection standards, grease bearing gland, sealing surface, oil pipe, etc. of the reduction
supply standards, and intactness standards. Any issues gearbox; in case of abnormal noise, local heating (especially at
identified during the inspection should be promptly addressed the bearing position) during operation, shut down the machine
by shutting down the equipment to identify the cause and for inspection and handling when necessary. Tenthly, inspect
