Operating principle and characteristics:
The series HGL, HG pump is really a type of single-stage and single-cylinder rotary piston vacuum pump. It truly is considerably improved series H rotary piston pump and consists of 4 patents; its common abilities have a good improvement.
Rotary piston vacuum pump is actually a type of vacuum manufacturing tools appropriate for pumping ordinary gases and condensable gases(whenever a gasoline ballast employed). The pump have to be fitted with ideal add-ons if gasoline is rich in oxygen, explosive, corrosive to ferrous metal, chemical reactive with vacuum pump oil.
Operation principle display in doing work 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 modified repetitively, so that pumping goal might be accomplished.
The series HGL, HG pump is often a backing pump when mixed with yet another higher vacuum pump at the same time as operate singly. It can be widely utilized in vacuum smelting, vacuum drying, vacuum impregnation and substantial vacuum simulation testing,etc.
