As an important member of the ring test industry, the high and low temperature test chamber plays a very important role in our experiments. However, during use, noise always appears in our ears. Users are paying more and more attention to the mute effect of high and low temperature experimental boxes. How to effectively reduce the noise problem of high and low temperature test chambers?
First, the appropriate four corners of the high and low temperature experimental box
The high and low temperature test chamber is 3-6 cm high and the balance of the four corners is adjusted to increase the air convection space at the bottom of the box. In this way, compressor noise and other noise from the bottom of the cabinet are removed from the bottom of the cabinet, reducing noise from both sides and upper portions of the high and low temperature chambers.
Second, the compressor base should be firm
If the compressor is pressed tightly by hand, the noise is significantly reduced, and the noise is increased by hand. This is generally caused by uneven force on the fixed damping pad of the compressor base or loose bolts and unstable compressor bottom plate. The connecting part bolts should be adjusted and tightened and the loss of the elastic washer should be replaced.
Third, the pipeline and high and low temperature experimental box body reinforcement
Check whether the connection reinforcement between the outer pipe and the casing is loose, so as to avoid resonance when the high and low temperature test chamber compressor works. In order to avoid loosening, the outer pipe must be fixed, and the bolt should be spring washer.
