Careful maintenance of industrial chillers can minimize the occurrence of failures, but it is impossible to completely eliminate failures. Because the materials used, the structure of the unit, the quality of installation, the method of use, and the level of operation are different. Then let's take a look together!
We want to ensure the safe, stable, cost-effective and long-term normal operation of industrial chillers, so it is very important to find hidden dangers of failure as early as possible during use. As an operator of the chiller, you not only need to be proficient in operation, but also to be able to achieve this goal through the "one look, two touch, three listen, four thinking" skills.
One look, how to look? What to look at For example, the screw chillers, air-cooled chillers, and water-cooled chillers of Ruihongkang Refrigeration series are equipped with high and low pressure pressure gauges on the front of the fuselage, and there are oil pressure gauges inside. You can directly see these chillers The high and low pressure values during operation, the oil pressure values, and the parameters of the inlet and outlet water pressure of the cooling water and chilled water. These parameters meet the requirements of the set operating conditions as normal, and the parameters that deviate from the requirements of the operating conditions are abnormal.
The second touch, as the name suggests, has to be in contact with industrial chillers. I usually touch the parts and pipes of the chiller, such as air pipes, liquid pipes, water pipes, oil pipes, etc., and feel the working temperature and vibration of the compressor, the inlet and outlet temperature of the evaporator and condenser, and the oil stains at the pipe joints. And distribution.
The third listening is to listen to the operating industrial chiller for abnormal sound, so as to judge the nature and location of the fault. The most important thing is to listen to the compressor, lubricating oil pump, solenoid valve of the system, throttle valve and other equipment for abnormal noise.
Four thinking refers to the comprehensive analysis of the operating data and materials of the industrial chiller obtained from the above three analysis and judgment methods, to find the basic cause of the failure, and to take necessary emergency measures to save time, material, and money. exclude.
