ROTARY PISTON VACUUM PUMPS

Operating principle and options:
The series HGL, HG pump is usually a form of single-stage and single-cylinder rotary piston vacuum pump. It truly is greatly enhanced series H rotary piston pump and includes four patents; its general capabilities possess a great improvement.
Rotary piston vacuum pump is often a kind of vacuum production equipment appropriate for pumping ordinary gases and condensable gases(when a gas ballast employed). The pump have to be fitted with suitable accessories if gas is wealthy in oxygen, explosive, corrosive to ferrous metal, chemical reactive with vacuum pump oil.
Operation principle display in functioning 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 transformed repetitively, so that pumping function could be accomplished.
The series HGL, HG pump may be a backing pump when combined with another higher vacuum pump also as operate singly. It is actually widely utilized in vacuum smelting, vacuum drying, vacuum impregnation and substantial vacuum simulation testing,and so forth.
