ROTARY PISTON VACUUM PUMPS

Working principle and functions:
The series HGL, HG pump is usually a form of single-stage and single-cylinder rotary piston vacuum pump. It truly is tremendously enhanced series H rotary piston pump and contains four patents; its basic abilities possess a wonderful improvement.
Rotary piston vacuum pump is really a sort of vacuum manufacturing products suitable for pumping ordinary gases and condensable gases(whenever a gas ballast applied). The pump should be fitted with proper equipment if gasoline is rich 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 purpose could be achieved.
The series HGL, HG pump might be a backing pump when mixed with another high vacuum pump also as operate singly. It can be widely utilized in vacuum smelting, vacuum drying, vacuum impregnation and high vacuum simulation testing,and so forth.
