Five common failures and maintenance methods for high and low temperature test chambers

The high and low temperature test box is mainly used for the adaptability test of electrician, electronic product, other components and other materials during storage, transportation and use under high temperature and low temperature environment. There are five types of problems such as sudden failure during its operation.
1. The temperature is not reduced or the temperature cannot be reduced. 1 The compressor is damaged or not opened. Replace the compressor and check whether the compressor circuit and the control components are damaged. 2 The refrigerant leaks. Use nitrogen leak detection method to find the leak point, welding, pumping Vacuum, add refrigerant, re-commission 3 solenoid valve operation is abnormal, replace the solenoid valve, check the solenoid valve control line 4 capillary blocked, replace the capillary, replace the dry filter, purge the condensate system impurities with nitrogen, add the refrigerant debugging 5 condenser Freeze, heat up and dry the inside of the box, reduce the temperature 2, do not heat up or heat up to less than 1 heating pipe damage (replacement can be)

2 Solid state relay damaged, replace it 3, humidity does not rise or humidity 1 humidified tube is damaged, replace 2 to control the level of humidification float float is not floated 3 wet solid state relay is damaged 4, humidity shows 100% RH

1 Abnormal gauze, replace the gauze 2 Refrigeration system failure, check the cooling system 3 water system water supply anomalies, check the water system 5, high and low temperature alternating damp heat test box main power switch trip 1 device total power exceeds the power switch total current, replace the appropriate power supply Switch 2 equipment leakage, check equipment, compressors, motors, heating tubes, humidifiers, condensers, fans, transformers, switching power supplies, pumps and other components insulation resistance and leakage current
