活塞式空压机工艺系统中,一般都装设放空管使空压机能在空载及无背压（二级缸后无压力）下起动,而对空压机能否在荷载及背压下起动?能否在空载及背压下起动?亦即仅关闭减荷阀使空压机不吸气或顶开吸气阀片使空压机不排气,而不装设放空管情况下起动,以及在后两种条件下进行起动会出现那些问题?对电机和电源会产生那些影响?……对这些问题,我们心中无数。因此,遵照伟大领袖毛主席的“这些问题的解决,一点也不能离开实践”的教导,我们进行一些实践测定,现将测定情况介绍如下:
Piston air compressor technology system, generally equipped with vent tube so that the air compressor can be no load and no back pressure (no pressure after the second cylinder) under the start, and the air compressor can load and back Can start under no-load and back-pressure? That is to say, only close off-load valve so that air compressor does not suck air or open air-sucking valve to make air compressor not to vent without airing What happens to the motor and the power supply when starting up the tube and starting up in the latter two conditions? ... We have countless questions on these issues. Therefore, in conformity with the teachings of Chairman Mao, the great leader, “these problems can not be solved without any practice”, we have conducted some practical tests and the present situation of measurement is as follows:
