ROTARY PISTON VACUUM PUMPS

Operating principle and options:
The series HGL, HG pump is usually a type of single-stage and single-cylinder rotary piston vacuum pump. It’s enormously improved series H rotary piston pump and involves 4 patents; its general capabilities possess a great improvement.
Rotary piston vacuum pump is actually a sort of vacuum manufacturing products appropriate for pumping ordinary gases and condensable gases(whenever a gas ballast made use of). The pump should be fitted with ideal add-ons if gas is rich 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 inside 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 changed repetitively, to ensure that pumping objective may be achieved.
The series HGL, HG pump is usually a backing pump when combined with one more high vacuum pump also as operate singly. It truly is broadly utilized in vacuum smelting, vacuum drying, vacuum impregnation and high vacuum simulation testing,etc.
