Working principle and capabilities:
The series HGL, HG pump is often a kind of single-stage and single-cylinder rotary piston vacuum pump. It’s significantly improved series H rotary piston pump and contains 4 patents; its basic capabilities have a great improvement.
Rotary piston vacuum pump is actually a sort of vacuum production gear appropriate for pumping ordinary gases and condensable gases(whenever a gas ballast made use of). The pump need to be fitted with suitable equipment if gasoline is rich in oxygen, explosive, corrosive to ferrous metal, chemical reactive with vacuum pump oil.
Operation principle demonstrate in working principle graph: A rotary piston with slide valve across ecentric wheel driven by shaft in 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, to ensure pumping purpose could be accomplished.
The series HGL, HG pump could be a backing pump when mixed with an additional large vacuum pump too as operate singly. It really is broadly used in vacuum smelting, vacuum drying, vacuum impregnation and higher vacuum simulation testing,and so forth.
