When the Constant Temperature And Humidity Test Chamber fails, quick troubleshooting and repair are key.
First, if the power indicator light does not light up after the equipment is powered on, you should first check whether the power cord is plugged in properly, whether there is any disconnection, and confirm whether the power switch is damaged. At the same time, check whether the power supply voltage is correct. Domestic equipment is generally 380V three-phase five-wire or 220V single-phase three-wire. In addition, it is necessary to check whether the plug is in good contact with the power supply to ensure normal power supply.
Secondly, if the equipment does not respond after pressing the power switch, it is necessary to check whether the emergency stop switch is in the off state and it should be bounced up. Next, check whether the circuit in the box is broken. If there is a problem, it needs to be repaired in time. Use a multimeter to measure the on-off status of the power switch. If it fails, the power switch needs to be replaced. These steps help to quickly locate and solve power-related problems.
Furthermore, for abnormal temperature and humidity display during equipment operation, they need to be checked separately. For abnormal temperature, check whether the temperature controller and contactor are damaged, whether the heating tube is burned out, and whether the given value of the temperature controller is correct. For abnormal humidity, check whether the wet-bulb gauze is hung correctly and covers the temperature-sensing part of the sensor, whether the gauze is yellow or has reduced water absorption, whether there is water in the wet-bulb water tank or the water level is low, and whether the controller settings are correct. These checks help ensure the normal operation of the sensor and the heating and humidification system.
Finally, if the equipment does not refrigerate well or does not refrigerate at all during operation, check whether the given value of the temperature controller is correct and whether the contactor works when the temperature controller outputs a signal. At the same time, check whether the refrigerant is leaking. If there is a leak, refrigerant should be replenished in time. In addition, check whether the compressor is working properly. If there is a problem, check the voltage strength or replace the compressor. These steps cover the inspection and adjustment of key components and parameters of the refrigeration system.
By systematically checking key components such as power supply, wiring, sensors and refrigeration system, faults in Constant Temperature And Humidity Test Chamber can be quickly troubleshooted and repaired.
