ROTARY PISTON VACUUM PUMPS

Operating principle and options:
The series HGL, HG pump is really a kind of single-stage and single-cylinder rotary piston vacuum pump. It truly is drastically enhanced series H rotary piston pump and contains 4 patents; its common capabilities possess a excellent improvement.
Rotary piston vacuum pump can be a type of vacuum production tools ideal for pumping ordinary gases and condensable gases(when a gasoline ballast applied). The pump has to be fitted with appropriate equipment if gas is rich in oxygen, explosive, corrosive to ferrous metal, chemical reactive with vacuum pump oil.
Operation principle present in operating 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 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 altered repetitively, to ensure pumping objective may be accomplished.
The series HGL, HG pump is usually a backing pump when mixed with an additional large vacuum pump as well as operate singly. It is broadly used in vacuum smelting, vacuum drying, vacuum impregnation and higher vacuum simulation testing,and so forth.
