A large part of noises of the artificial climate incubator is caused by the compressor, because the compressor is an important component of the incubator, so how to solve the abnormal noises of the compressor?

First of all, when purchasing an artificial climate chamber, pay attention to comparing the materials and processing techniques used by the manufacturer. There are many reasons for the noise of the compressor, such as the sheet metal process. If the sheet metal design is unreasonable, and the material used for the chamber is poor, and the overall process is not good, it will be particularly prone to vibration, which will cause noise, and the noise will become louder over time.

After the lab artificial climate box has been used for a long time, the following aspects may cause noises:

1. Inhalation of liquid refrigerant causes liquid shock to adjust the system, in this case, release excess refrigerant;

2. Too much lubricating oil in the system causes liquid shock, so the lubricating oil system should be repaired to make it work normally;

3. The noise generated by the compressor cylinder and crankshaft, at this time, replace the compressor;

4. Check whether the shock absorbing spring is deformed. If it is deformed, it will affect the stability of the pressure regulating function and cause noise;

5. Check the degree of wear of the needle valve, whether the cone surface and the valve seat can fit tightly, if not, it will make the pilot flow unstable, so that the pressure fluctuation will cause noise;

6. Check whether air is mixed in the oil, forming cavitation and making noise.
