The constant temperature and humidity test chamber is in an optimal state, and in addition to its own performance, there are also operators' compliance operation methods and daily maintenance after the test. However, why is there noise in the constant temperature and humidity test chamber? This is the place where the operators are troubled! When the noise of the test machine occurs, a large part is caused by the compressor problem, how to proceed on the problem. What about processing?
When the test box compressor is noisy, it should be considered whether it is caused by the sheet metal process, and it may be caused by vibration problems due to design problems or material problems. How to solve in many situations that cause problems:
1. It should be checked whether the shock absorbing spring is deformed. If the deformation occurs, it will affect the stability of the pressure regulating function and cause noise;
Second, check whether the air is mixed with air to form a cavitation phenomenon. If the component is deformed and worn, it only needs to be replaced. If air is mixed into the oil, it should be removed in time and the seal should be sealed to prevent air from re-entering. To reduce noise;
Third, the system has too much lubricating oil to produce liquid hammer, and the lubricating oil system should be overhauled;
4. The operation of the liquid hammer adjustment system caused by the inhalation of the liquid refrigerant should release excess refrigerant.
Some minor faults may directly affect the normal operation of the large test. Therefore, it is necessary to judge the cause, and the various treatments of the constant temperature and humidity test chamber are paving the way for accurate tests.
