Operating principle and characteristics:
The series HGL, HG pump is really a form of single-stage and single-cylinder rotary piston vacuum pump. It is greatly improved series H rotary piston pump and includes 4 patents; its basic abilities have a good improvement.
Rotary piston vacuum pump is often a sort of vacuum production equipment ideal for pumping ordinary gases and condensable gases(when a fuel ballast utilised). The pump should be fitted with ideal equipment if gasoline is wealthy 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 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 changed repetitively, in order that pumping goal could be achieved.
The series HGL, HG pump might be a backing pump when combined with yet another high vacuum pump too as operate singly. It is actually extensively utilized in vacuum smelting, vacuum drying, vacuum impregnation and high vacuum simulation testing,and so forth.
