Why does pneumatics machine need to classification compress? Compress be no good?
A lot of people know, two class suit compressor produce maximum pressure, one class suits to produce tolerance big. Occasionally, still need to undertake the compression of above twice, why to need to classification compress? Small today make up arrange everybody. When asking aeriform actuating pressure is higher, use only course to compress not only wasteful, be impossible to come true even sometimes, must use multistage to compress. Multistage is compressed even if gas from inspiratory begin, pass step up a few times and achieve the actuating pressure of a need.
