Noise in the high and low temperature test chamber

There are  the high and low temperature test chamber several reasons:

1. Too much refrigerating oil enters the evaporator, it will produce a gurgling bubble sound.

2. Compressor condenser fixing screws or nuts are loose, water receiving plate is loose, etc.

3. the high and low temperature test chamber  As the pipeline is suspended for a long time, the same vibration is prone to occur when the pipeline is vibrated, and the noise is obviously increased, showing periodic fluctuations. When pressed into the vibration-prone parts, the noise is significantly reduced or eliminated. According to different situations, measures such as reinforcement, buffering, isolation, etc. can be taken, such as damping mortar, rubber sleeve, etc.

4. The abnormal noise of the  the high and low temperature test chamber  cylinder is caused by the cylinder falling off, the compressor spring loose, the internal parts are severely worn, and the lubrication is poor. The capillary outlet is not smooth. Without a special capillary clamp, the outlet cannot be around 45 degrees.

5. Poor vacuum evacuation, producing grunting noise, which is manifested by uneven condenser temperature.
