Operating principle and features:
The series HGL, HG pump is often a kind of single-stage and single-cylinder rotary piston vacuum pump. It is enormously improved series H rotary piston pump and consists of 4 patents; its standard abilities possess a fantastic improvement.
Rotary piston vacuum pump is actually a kind of vacuum production tools suitable for pumping ordinary gases and condensable gases(whenever a fuel ballast utilized). The pump needs to be fitted with ideal equipment if gas is rich in oxygen, explosive, corrosive to ferrous metal, chemical reactive with vacuum pump oil.
Operation principle present in working principle graph: A rotary piston with slide valve across ecentric wheel driven by shaft inside the housing. Piston pole can slide and swing freely in arch track. The entire pump chamber is divided into chamber A and chamber B by piston. When shaft rotates the volume of chamber A and chamber B are altered repetitively, in order that pumping purpose could be accomplished.
The series HGL, HG pump could be a backing pump when mixed with another substantial vacuum pump also as operate singly. It truly is widely used in vacuum smelting, vacuum drying, vacuum impregnation and large vacuum simulation testing,and so forth.
