ROTARY PISTON VACUUM PUMPS

Operating principle and characteristics:
The series HGL, HG pump is often a sort of single-stage and single-cylinder rotary piston vacuum pump. It truly is greatly enhanced series H rotary piston pump and includes 4 patents; its standard abilities possess a good improvement.
Rotary piston vacuum pump can be a type of vacuum production products ideal for pumping ordinary gases and condensable gases(when a gas ballast applied). The pump should be fitted with proper equipment if gasoline is wealthy in oxygen, explosive, corrosive to ferrous metal, chemical reactive with vacuum pump oil.
Operation principle display in operating 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 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, in order that pumping function can be achieved.
The series HGL, HG pump is often a backing pump when combined with yet another higher vacuum pump too as operate singly. It truly is broadly used in vacuum smelting, vacuum drying, vacuum impregnation and higher vacuum simulation testing,and so on.
