ROTARY PISTON VACUUM PUMPS

Operating principle and functions:
The series HGL, HG pump is often a form of single-stage and single-cylinder rotary piston vacuum pump. It really is greatly improved series H rotary piston pump and involves 4 patents; its general capabilities possess a fantastic improvement.
Rotary piston vacuum pump is actually a kind of vacuum production products suitable for pumping ordinary gases and condensable gases(when a gas ballast utilized). 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 working 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 changed repetitively, to ensure that pumping function may be achieved.
The series HGL, HG pump is usually a backing pump when combined with yet another substantial vacuum pump as well as operate singly. It’s widely utilized in vacuum smelting, vacuum drying, vacuum impregnation and high vacuum simulation testing,and so forth.
