Interpretation of thermal shock test box failure inspection analysis

Thermal and thermal shock test chamber is used to test the resistance of electronics, automobiles, rubber, plastics, aerospace technology, communication equipment and other products under changes repeated cold and heat.

 First, check the following two things:
1. If the circulating water light on the display screen is flashing red
2. If the pressure insufficient circulating water, part fault display There are several reasons for this situation. Please check the following items one by one:
1. Check whether the power supply of the cooling water tower is turned on
2. Check whether there is water in the tower
/> 3. Is the cooling water tower pump motor damaged? :
1. If the pressure of the circulating water in the cold and thermal shock test chambere is insufficient during the test and the circulating water light on the display screen is red and flashing,
It means tDuring this period, the following situations 1 and 2 have occurred. However, the fault signal was automatically eliminated at this time.
2. If the pressure of the circulating water in the cold and thermal shock test chamber is insufficient during the test and the circulating water indicator on the screen is lit in red and does not flash, there are several reasons. for this situation. Please solve the problems one by one according to the following:
1. Please turn on the power supply of the cooling water tower!
2. Please check if there is any problem with the cooling system water supply system. water tower, and whether the water inlet part is on! 3. Please inform the utility company to replace the motor.
4. If not, please do maintenance. The manufacturer of the cold and thermal shock test chamber recommends that you set it outside to freeze it for maintenance and cleaning! Also, overheating the watersteam during the humidification process will not add additional heat to the system. In addition, when the temperature of the spray water is controlled to be lower than the key point temperature required by the test, the spray water has a dehumidifying effect
