ROTARY PISTON VACUUM PUMPS

Operating principle and attributes:
The series HGL, HG pump can be a form of single-stage and single-cylinder rotary piston vacuum pump. It’s greatly improved series H rotary piston pump and involves 4 patents; its general capabilities possess a fantastic improvement.
Rotary piston vacuum pump is really a kind of vacuum production products suitable for pumping ordinary gases and condensable gases(when a gas ballast used). The pump have to be fitted with acceptable equipment if gasoline is wealthy in oxygen, explosive, corrosive to ferrous metal, chemical reactive with vacuum pump oil.
Operation principle present in doing work principle graph: A rotary piston with slide valve across ecentric wheel driven by shaft within 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, to ensure that pumping goal may be achieved.
The series HGL, HG pump is usually a backing pump when mixed with yet another substantial vacuum pump likewise as operate singly. It’s widely utilized in vacuum smelting, vacuum drying, vacuum impregnation and high vacuum simulation testing,and so on.
