Analysis of the causes of high and low temperature alternating heat and humidity test chamber failure alarm?
During the use of the high and low temperature alternating heat and humidity test chamber, there are inevitably some unexpected situations, so the engineers installed an induction alarm system on the outside of the test box. When there is an abnormal situation in the high and low temperature alternating heat and humidity test chamber, an alarm signal will be issued. Then, what abnormal conditions appear in the test box will cause the alarm system to send a signal? Here is the answer for everyone:
1: The induction system will alarm when the temperature inside the test chamber is too high. At this time, we should immediately cool down the box and do not open the door immediately to avoid burns.
2: When the fan of the test box is overheated or overcurrent, an alarm sounds.
a: When the fan coil is overheated, the equipment stops and alarms. We must solve the fault to continue the test, otherwise it is very dangerous.
b: When the fan current crosses the allowable value, the equipment stops and alarms, and the equipment must be allowed to resume normal operation after the overcurrent fault repair is completed.
3: The refrigeration and heating compressors overheat will also alarm. Due to the long working hours, it may be caused by the failure of the refrigeration and heating system, which causes the compressor to heat up very quickly. At this time, we must stop the test, check the problem of the compressor, and repair it before we can Put into use.
4: The operator's improper operation of the high and low temperature alternating heat and humidity test box alarm system will also be reminded. When the operator operates the test chamber, it will also alarm when the temperature is set too high or the humidification value is too high.
