How to maintain the radiator
2019-04-19
How to maintain the radiator First, check the radiator interface for leaks During the heating period, the surface temperature of the radiator is high, so there will be a phenomenon of thermal expansion and contraction, especially at the pipe joint, which is the main point of water leakage. Once the heating is stopped, the interface is loose, which will cause water leakage. Therefore,...

Analysis of 10 major failure phenomena commonly seen in refrigeration equipment maintenance
2019-07-05
1. The exhaust gas temperature of the refrigeration system is too low: The low exhaust pressure is mainly caused by the small or even stop flow of the refrigerant in the refrigeration system. The exhaust pressure is too low, although the phenomenon is manifested at the high pressure end, but the cause is mostly caused by the low pressure end. Common reasons for low exhaust pressure: 1) T...
