What should I do if the noise of the high and low temperature test chamber is too loud?

Date: Apr 23,2021 Views: 333

Excessive noise in the high and low temperature test chamber

Answer: 1. Too much refrigerating oil enters the evaporator, and the high and low temperature test chamber will produce a "gurgling" bubble sound.

2. The compressor condenser fixing screw or nut of the high and low temperature test box is loose, and the water receiving plate is loose.

3. Pipeline vibration As the pipeline is suspended for a long time, co-seismic phenomenon is prone to occur, and the noise increases significantly and exhibits periodic fluctuations. When pressing into each vibrating part, when pressing into a certain part, the noise is obviously 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 scraping cylinder is caused by the cylinder falling off, the compressor spring loosening, the internal parts of the high and low temperature test chamber are severely worn, and the lubrication is poor. The capillary outlet is not smooth. Since there is no special capillary clamp, the outlet cannot be at an angle of about 45 degrees Celsius.

5. Insufficient vacuum evacuation, producing a "grunt" sound, which is manifested by uneven condenser temperature.
