The reason why the running time and temperature of the high and low temperature impact test chamber cannot be kept in balance

NOKI Chamber pm5:33

In order to better exert the working efficiency of the high and low temperature impact test chamber. Improve the service life of the product. And obviously it is in good working condition, and material tests can be carried out at any time to reduce the possibility of failure of the test box, increase its utilization rate, and reduce mechanical wear. Regular maintenance must be carried out. Next, I will introduce the reasons why the running time and temperature of the high and low temperature impact test chamber cannot be balanced.

I consulted Noki’s technical staff, and it can be considered that other customers have been working continuously for a long time, but it is not very accurate, because many users require less time, and it is likely that the test will be stopped after a few months, and the use of samples is also There will be problems. And this customer we know used a high and low temperature impact test box and let him work continuously for about 7 to 8 years, and it is still running.

In order to prevent users from leaking during use, manufacturers of high and low temperature impact test chambers basically install a variety of protective measures to ensure that users can stop the operation of the equipment in time and give feedback on the cause of the failure in the event of user misoperation. The protective measures of the high and low temperature impact test chamber can not only ensure the safety of the operators, but also prevent irreparable failures and losses caused by improper operation. However, sometimes it is too sensitive to affect the normal test, which requires adjustments by itself or by technical personnel.

cord and parts of the equipment should be cleaned before use to ensure that there will be no leakage and other dangerous accidents during use. It is also necessary to determine whether the temperature of the sample is high before the experiment, and avoid dangers such as spontaneous combustion and explosion caused by excessive temperature in time.

The reason why the temperature can’t keep balance

1. When there is a problem with the high and low temperature impact test chamber, first check whether the refrigeration compressor can start smoothly during its operation. If it can be started, it means that the electrical circuit of the test box from the main power supply to the compressor is normal, and there is no problem with the electrical system of the test box.

2. When problems unrelated to the electrical system occur, continue to check the refrigeration system; first check the two sets of refrigeration compressors. If the suction and discharge pressure of the low-temperature (R23) compressor is lower than the normal value, and the suction pressure is in the suction state, it indicates that the refrigerant quantity of the main refrigeration unit is obviously insufficient; touch the R23 compressor exhaust pipe and the exhaust pipe on the main body of the test chamber by hand. Suction tube. If it is found that the temperature of the exhaust pipe is not high, and the temperature of the suction pipe is not low (no frost), it means that the host lacks R23 refrigerant.

The contents explained above are related to the reasons why the running time and temperature of the high and low temperature impact test chamber cannot be balanced. I hope that after reading it, it will be helpful to you.
