Daily use of high and low temperature test chamber knowledge

Choosing a good quality high and low temperature test chamber requires daily maintenance to make it play a higher role. The high and low temperature test chamber is mainly used for product related performance testing under high temperature and low temperature conditions to determine whether the performance of the product can be Meet the predetermined requirements.

1. Frequently clean the dust-prone parts of the high and low temperature test chamber. For example, the circulating fan blades and condenser fans will condense a lot of small particles such as dust, and they should be cleaned regularly.

2. When the test chamber is in trial operation, strictly check the operating direction of the compressor. When it is found to be reversed, stop it immediately, cut off the power supply, reverse any two of the three-phase wires and restart it. Otherwise, the compressor will be damaged.

3. Circuit breakers and over-temperature protectors provide the machine's test products and operator's safety protection, so please check the circuit and other components regularly.

4. When the test equipment is working, regularly inspect the compressor safety valve and other protection systems. Ensure that it is sensitive and reliable.

5. Keep the waterway of the high and low temperature test chamber unblocked and the humidifier clean. If the waterway is not smooth and the humidifier is fouled, it will easily cause the humidifier to dry out and may damage the humidifier. Therefore, the waterway and humidifier must be cleaned regularly.

6. It is not advisable to start the compressor frequently during the test, and the interval between compressor starts is 15 minutes.

7. When the low temperature operation is completed, be sure to set the temperature condition to 60°C for drying for about half an hour, so as not to affect the measurement time of the next working condition or freeze.
