Operating principle and attributes:
The series HGL, HG pump is a kind of single-stage and single-cylinder rotary piston vacuum pump. It can be significantly improved series H rotary piston pump and consists of four patents; its common capabilities possess a fantastic improvement.
Rotary piston vacuum pump is usually a kind of vacuum manufacturing gear ideal for pumping ordinary gases and condensable gases(whenever a gasoline ballast utilised). The pump need to be fitted with proper add-ons if gas is wealthy in oxygen, explosive, corrosive to ferrous metal, chemical reactive with vacuum pump oil.
Operation principle display in doing work 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, to ensure that pumping purpose might be attained.
The series HGL, HG pump could be a backing pump when combined with an additional large vacuum pump at the same time as operate singly. It is extensively utilized in vacuum smelting, vacuum drying, vacuum impregnation and high vacuum simulation testing,and so forth.
