Maintenance and inspection of high and low temperature test chamber

In order to ensure the safe and reliable operation of the refrigeration system and prolong the service life of the compressor, please pay attention to the daily maintenance:

1. Before starting the compressor:

(1) Whether the suction and exhaust shut-off valve and the valve that should be opened in the system are in the correct position.

(2) Check whether the power supply voltage and ambient temperature are within the specified range.

2. The compressor is running:

(1) The suction and discharge pressure of the compressor should not exceed the range of use, and listen to the running sound of the compressor. Except for the clear up-and-down sound of the intake and exhaust valves, other components should not have percussion sounds.

(2) Leakage should be dealt with in time
