Methods of reducing noise in thermal shock test chamber

1. Look at the spring of the compressor. When the damping spring of the compressor is deformed, the pressure regulation will become unstable, causing the compressor to produce large pressure fluctuation noise during operation. At this time, the spring needs to be replaced. At the same time, pay attention to the abnormal noise of the compressor. The piston collides with the exhaust valve during the operation of the compressor. Confirm that the exhaust valve bolts are loose, if the valve plate and bearing are damaged, replace with new accessories.thermal shock test chamber

2. Take corresponding thermal shock test chamber noise reduction measures to the cabinet, mainly sticking the sound insulation cotton to the sealing plate, which can achieve a good noise reduction effect. Reasonable design of convection and heat dissipation vents can reduce the operating noise of the compressor. In addition, check whether the fixing screws are loose. If they are loose, tighten the fixing screws.

3. Check the oil level thermal shock test chamber. The refrigerating oil should not be too much or too little, and the excess refrigerating oil should be disposed of. It is also possible to appropriately reduce the refrigerant, or reduce the addition of refrigerant.
