ROTARY PISTON VACUUM PUMPS

Working principle and attributes:
The series HGL, HG pump is often a form of single-stage and single-cylinder rotary piston vacuum pump. It can be enormously improved series H rotary piston pump and consists of 4 patents; its standard abilities have a great improvement.
Rotary piston vacuum pump can be a type of vacuum production tools suitable for pumping ordinary gases and condensable gases(whenever a fuel ballast utilized). The pump has to be fitted with proper add-ons if gasoline is rich in oxygen, explosive, corrosive to ferrous metal, chemical reactive with vacuum pump oil.
Operation principle show in operating 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 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 objective may be accomplished.
The series HGL, HG pump is usually a backing pump when combined with a further large vacuum pump also as operate singly. It really is broadly used in vacuum smelting, vacuum drying, vacuum impregnation and higher vacuum simulation testing,and so forth.
