Operating principle and capabilities:
The series HGL, HG pump is usually a kind of single-stage and single-cylinder rotary piston vacuum pump. It can be greatly enhanced series H rotary piston pump and consists of 4 patents; its standard abilities possess a excellent improvement.
Rotary piston vacuum pump is often a type of vacuum production products suitable for pumping ordinary gases and condensable gases(when a gas ballast utilized). The pump have to be fitted with acceptable accessories 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 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 transformed repetitively, to ensure pumping objective could possibly be achieved.
The series HGL, HG pump is usually a backing pump when mixed with a different substantial vacuum pump likewise as operate singly. It truly is extensively utilized in vacuum smelting, vacuum drying, vacuum impregnation and high vacuum simulation testing,and so forth.
