ROTARY PISTON VACUUM PUMPS

Operating principle and capabilities:
The series HGL, HG pump is a type of single-stage and single-cylinder rotary piston vacuum pump. It truly is significantly enhanced series H rotary piston pump and consists of four patents; its standard abilities possess a wonderful improvement.
Rotary piston vacuum pump is usually a type of vacuum production tools suitable for pumping ordinary gases and condensable gases(when a gas ballast employed). The pump has 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 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 modified repetitively, so that pumping objective could possibly be achieved.
The series HGL, HG pump is often a backing pump when mixed with a further substantial vacuum pump as well as operate singly. It can be extensively utilized in vacuum smelting, vacuum drying, vacuum impregnation and higher vacuum simulation testing,and so on.
