1.Hot and cold shock test chamberOne of the faults——Overtemperature

The cold and hot shock test chamber has an independent over-temperature protection thermostat. The general overtemperature alarm problem is:

1The thermostat setting is too low. This is an operational failure. Only the thermostat setting needs to be adjusted higher. Most of the factory settings are220℃.

2The temperature value displayed by the instrument obviously exceeds the set control temperature value: it may be that the temperature control element is broken down, the instrument is faulty or the control circuit is faulty, and we should check and replace it.

2. cold and hot shock test chamber failure II——Overpressure

1Check the pressure value set by the pressure controller, generally1.8MpaIf it is low, adjust it.

22. The heat exchange of the condenser is not good, so the condenser should be cleaned.

3Other refrigeration system failures, find professionals to check

3. Cold and Hot Shock Test Chamber Failure III——Water cut off

Water cut-off means that the water tank is short of water. The general problems are:

1The water level of the water tank is not increased to a specific position when the water is added for the first time.

2A certain place of the water supply pipeline is blocked, especially the water inlet of the water gauge of the water tank, which can be dredged

32. The water cut-off protection thermostat shall be set110℃, if it is low, adjust well

4. cold and hot shock test chamber maintenance contact

If the cold and hot shock test chamber fails during the test, first check whether it is an operational failure. The judgment method is to check and check step by step according to the installation and use steps. If there is any deviation from the check and the operation can work normally according to the instructions, it is an operational failure. You can also find relevant technicians to check.
