Third, the constant temperature and humidity test chamber compressor is stuck
1. The reasons for the compressor jam are:
(1) There are dirty impurities in the lubricating oil;
(2) The oil pump oil pipeline is blocked, so that the cylinder oil-deficient piston is stuck;
(3) The handle pin of the oil pump main gear inserted into the crank is twisted, causing the oil system to break oil;

(3) the valve piece is broken;
(4) The sound of oil blown by the crankshaft crank or the big oil of the connecting rod;
2. There are abnormal sound elimination methods in the cylinder of the constant temperature and humidity test chamber compressor:
