一、绪 言 往复式压缩机上的自动阀是很重要的部件。如果阀的阻力大,压缩机效率就低。此外,如果阀坏了,不但减少排气量,还会使阀的破皮撞伤气缸,或因逆流的排气再压缩产生过热现象,从而引起活塞之烧伤等。尤其是各工厂都希望在压缩机定期检修期间内,阀最好不发生故障。 First, the introduction Reciprocating compressor on the automatic valve is a very important component. If the valve resistance, compressor efficiency is low. In addition, if the valve is broken, not only to reduce the displacement, but also make the valve broken skin hit the cylinder, or due to counter-current exhaust compression and overheating, causing the piston burns. In particular, the plants are hoping that the valve should preferably not fail during regular compressor servicing.
