Working principle and attributes:
The series HGL, HG pump is really a sort of single-stage and single-cylinder rotary piston vacuum pump. It really is drastically enhanced series H rotary piston pump and involves 4 patents; its general capabilities possess a wonderful improvement.
Rotary piston vacuum pump is often a sort of vacuum manufacturing gear ideal for pumping ordinary gases and condensable gases(when a gasoline ballast made use of). The pump must be fitted with ideal add-ons if gasoline is rich in oxygen, explosive, corrosive to ferrous metal, chemical reactive with vacuum pump oil.
Operation principle display in operating principle graph: A rotary piston with slide valve across ecentric wheel driven by shaft within the housing. Piston pole can slide and swing freely in arch track. The whole pump chamber is divided into chamber A and chamber B by piston. When shaft rotates the volume of chamber A and chamber B are changed repetitively, in order that pumping purpose can be achieved.
The series HGL, HG pump could be a backing pump when combined with an additional large vacuum pump also as operate singly. It is actually extensively used in vacuum smelting, vacuum drying, vacuum impregnation and higher vacuum simulation testing,and so on.
