Careful maintenance of the industrial chiller can minimize the occurrence of faults, but it is impossible to eliminate the failure completely. Because of the material, the structure of the unit, the quality of the installation, the method of use and the level of operation are different. We need to ensure the safety and stability of industrial water chiller and the long-term normal operation of economic efficiency. It is very important to find out the hidden trouble in the process of use. So for a professional maintenance staff what should we do, as a cold water machine operation personnel, not only need skilled operation, more to practice one can quickly resolve the cold water machine fault is very important, to quickly solve the problem through "a see, two touch, three, four want to" the ability to achieve this goal.
A look at，What do you see? Such as the east leaps series of screw chiller, the wind cold water machine, water, cold water machine, they are on the front part of the equipped with high and low pressure gauge, there is oil pressure gauge, can directly see the chiller running high, low pressure value, oil pressure value, and the parameters of the import and export pressure of cooling water, chilled water, etc. These parameters meet the requirements of the set operating conditions, and the parameters deviated from the operating conditions are abnormal.
Second touch, as the name implies, contact with industrial water chiller. Tend to use hand touch water chiller parts and pipes, such as tube, fluid pipe, water pipe, tubing, etc., and feel the compressor working temperature and vibration, import and export temperature of the evaporator, condenser, oil pipe joint and distribution, etc.
Three listen, is to use ear to listen to the industrial water chiller in operation to have the abnormal sound, so that the fault occurrence of the character and position. The most important is to listen to the compressor, lubricating oil pump, the system of the solenoid valve, throttle valve and other equipment abnormal sound.
Four think, it is to point to from the above three analysis the judgment methods of industrial cold water machine operation and comprehensive analysis of data and materials, find the main causes of the failure, and take necessary emergency measures, so as to save time, save material, save money to troubleshooting.
