Working principle and characteristics:
The series HGL, HG pump is a form of single-stage and single-cylinder rotary piston vacuum pump. It really is greatly improved series H rotary piston pump and consists of four patents; its basic abilities possess a fantastic improvement.
Rotary piston vacuum pump is really a kind of vacuum manufacturing tools suitable for pumping ordinary gases and condensable gases(when a gas ballast utilized). The pump have to be fitted with acceptable add-ons if gas is rich in oxygen, explosive, corrosive to ferrous metal, chemical reactive with vacuum pump oil.
Operation principle show in working 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 entire 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, to ensure pumping objective can be accomplished.
The series HGL, HG pump is usually a backing pump when combined with another substantial vacuum pump too as operate singly. It is actually extensively used in vacuum smelting, vacuum drying, vacuum impregnation and high vacuum simulation testing,and so forth.
