Operating principle and functions:
The series HGL, HG pump is really a form of single-stage and single-cylinder rotary piston vacuum pump. It can be considerably enhanced series H rotary piston pump and incorporates 4 patents; its basic abilities have a wonderful improvement.
Rotary piston vacuum pump can be a type of vacuum manufacturing products appropriate for pumping ordinary gases and condensable gases(when a fuel ballast utilized). The pump should be fitted with ideal add-ons if gas is wealthy in oxygen, explosive, corrosive to ferrous metal, chemical reactive with vacuum pump oil.
Operation principle present in doing work 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 transformed 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 can be widely utilized in vacuum smelting, vacuum drying, vacuum impregnation and substantial vacuum simulation testing,and so forth.
