1. Overview
Preventive maintenance is a maintenance that is carried out at predetermined time intervals or in accordance with prescribed criteria to reduce the probability of product failure or prevent functional degradation, mainly including adjustments, regular inspections and necessary repairs. Make equipment maintenance and operators familiar with the performance, structural principle, use method and precautions of the product, make the equipment play its due function.
Carry out maintenance to ensure that the equipment is in good working condition.
2. Operator monitoring
The operator monitors the status of the equipment when it is in normal use, in order to detect potential failures.
Once the operator finds that there is a fault alarm in the system, he should quickly confirm and check the fault to find the cause of the fault.
3. Use inspection
When the operator is using the equipment normally, regular inspections are carried out according to the plan to determine whether the product performs the specified function.
a) Check whether the connections of supply and return pipelines, power lines, etc. are in good condition;
Inspection requirements: There is no leakage at each pipeline and connection, and no damage to the cable;
Inspection method: visual inspection;
b) Check whether the liquid return pressure (back pressure) is low, and replenish the liquid in time;
Inspection requirements: The value of the return liquid pressure is higher than 0.05MPa (observe the main interface of the touch screen or the 1# pressure gauge), if the pressure is lower than this value, it needs to be replenished;
Inspection method: visual inspection, data comparison;
c) Check the liquid supply system, and record the temperature, pressure and other data every half a day;
Inspection requirements: record supply/return liquid temperature, supply/return liquid pressure, supply liquid flow data, and observe whether the data tends to be stable in long-term operation;
Inspection method: visual inspection, data comparison;
d) Check the fault alarm conditions of the system, such as: temperature, pressure, flow rate, etc. (the above fault states are displayed on the "fault alarm screen" on the touch screen), and record them every half a day.
Inspection requirements: check the system alarm points, and refer to the instruction manual for troubleshooting;
Inspection method: visual, on-demand;
*Note: This is the water-cooled container parameter of AVIC 1.3 version. If your product is from other manufacturers or other versions, it may be slightly different from this parameter. This parameter is for reference only.
