Operating principle and options:
The series HGL, HG pump is usually a kind of single-stage and single-cylinder rotary piston vacuum pump. It really is considerably improved series H rotary piston pump and incorporates four patents; its basic capabilities have a great improvement.
Rotary piston vacuum pump is often a sort of vacuum production gear suitable for pumping ordinary gases and condensable gases(whenever a fuel ballast made use of). The pump needs to be fitted with ideal add-ons if gasoline is wealthy in oxygen, explosive, corrosive to ferrous metal, chemical reactive with vacuum pump oil.
Operation principle display in functioning 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 transformed repetitively, to ensure pumping function might be accomplished.
The series HGL, HG pump could be a backing pump when combined with a different substantial vacuum pump as well as operate singly. It can be broadly used in vacuum smelting, vacuum drying, vacuum impregnation and high vacuum simulation testing,and so forth.
