Latest company news about Constant Temperature And Humidity Test Chamber Maintenance Knowledge

Maintenance knowledge of constant temperature and humidity test chamber:

In the use of the machine is inevitable to appear this or that fault, so understand some constant temperature and humidity test chamber maintenance knowledge necessary, the following will tell a constant temperature and humidity test chamber maintenance.

 

First, what are the common failures of the constant temperature and humidity test chamber?

1. Refrigeration system: no cooling, no humidity, snow leakage, broken copper pipe aging, compressor jam, etc

2. Control system: temperature and humidity are not controlled, temperature and humidity control cannot work normally, and temperature and humidity sensor fails

3. Heating system: the heater loses its function, and the solid state relay, time relay and temperature limiter cannot operate normally

4. Humidification system: humidifier, filter, humidity sensor, wet cloth, circulating waterway and other failures

5. Mechanical system: motor burned out and circulation wind wheel fell off.

 

Second, constant temperature and humidity test chamber failure maintenance

Now introduce constant temperature and humidity test chamber temperature and humidity control, the solution of the condition of abnormal humidity

1. First check the underwater overtemperature protector in the control room to see if the temperature is 150℃

If it is not at 150℃, turn the underwater overtemperature protector to 150℃

2. Check whether the pipeline is too dirty in the machine room, resulting in the flow of water is not smooth

Total power off first, and then add wet barrel at the bottom of the drain valve, turn to the direction of the parallel to the line, when the tank water is light, use the wrench turn humidifying barrels, to do the internal because long-term moisture scale * *, and then pull out the silicone pipe, into the water to clean, clean the parts after finishing put back in place, and then open the total power supply

3. Check whether there is water in the upper tank. If not, check whether there is water in the lower tank

If there is no water in the water tank, just add water to the water tank.There is no water in the upper water tank, and there is water in the lower water tank, that is, the water motor in the lower water tank is broken. Please call haida after-sales service hotline 400-071-1808 and inform haida technician to come to the door to deal with it

4. Check whether the solid state relay has the phenomenon of burning out short circuit. First set the humidity value to 0%, and then check whether the humidifying bucket in the machine room is boiling.

If there is a short circuit, replace the humidity part of the solid state relay can be solved.
