How to fix the gas displacement insufficient of Temperature and humidity chamber(A)


Compressor is the core components of constant temperature and humidity test chamber for refrigeration, the compressor is actually responsible for lifting the pressure, the suction pressure state to the exhaust pressure state. Displacement insufficient is one of the most prone to failure of the compressor, the equipment appears such a problem is mainly due to the following reasons:
 
1. Constant temperature and humidity test chamber valve spring force and gas force to match the bad. The elasticity is too strong to make the valve open slowly, the elasticity is too weak, the valve is not closed in time, which not only affect the gas, but also affect the power increase, and valve block, spring life. At the same time, will also affect the gas pressure and temperature changes.
 
 
2. The intake filter failure: fouling blocked, so that the displacement reduced; the suction tube is too long, the diameter is too small, resulting in increased suction resistance affect the gas, to regularly clean the filter.
 
 
3.The rotate speed of Constant temperature and humidity test chamber compressor too low cause the displacement reduces, air compressor used improperly, because the air compressor displacement is based on a certain altitude, inspiratory temperature, and humidity design, when it is used in more than On the above-mentioned standard plateau, the suction pressure is reduced, and the displacement is inevitably reduced.
