A large part of the noise 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 response of the compressor? When purchasing an artificial climate incubator, pay attention to the The materials and processing techniques used by the manufacturers are compared
.
When the compressor makes noise, there are many reasons, such as the sheet metal process
.
If the sheet metal design is unreasonable, and the materials used in the test box are poor, and the overall process is not good, it will easily generate vibration, which will cause noise, and the noise will increase over time
.
After the artificial climate incubator has been used for a long time, when there is noise, the causes of the noise are as follows: 1.
Inhalation of liquid refrigerant causes liquid hammer to adjust the working condition of the system; (releasing excess refrigerant) 2.
The system lubricating oil is too hot 3.
Noise generated by the compressor cylinder and crankshaft; (need to replace the compressor) 4.
Check whether the shock absorber spring is deformed, if it is deformed, it will affect the pressure regulation 5.
Look at the wear degree of the needle valve, whether the cone surface and the valve seat can be tightly fitted, if not, the pilot flow will be unstable, resulting in noise caused by pressure fluctuations; 6.
Check whether the oil Air is mixed in, causing cavitation and making noise
.
If the parts of the incubator are deformed or worn, just replace it; if air is mixed in the oil, it must be removed in time and attention should be paid to sealing to prevent the air from re-entering, so as to reduce the noise
