ROTARY PISTON VACUUM PUMPS

Operating principle and capabilities:
The series HGL, HG pump is usually a kind of single-stage and single-cylinder rotary piston vacuum pump. It can be enormously improved series H rotary piston pump and consists of 4 patents; its general abilities have a great improvement.
Rotary piston vacuum pump is actually a kind of vacuum manufacturing tools ideal for pumping ordinary gases and condensable gases(whenever a fuel ballast utilized). The pump need to be fitted with ideal equipment if gas is rich 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 inside 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 altered repetitively, to ensure that pumping function could be accomplished.
The series HGL, HG pump may be a backing pump when combined with a further substantial vacuum pump also as operate singly. It really is widely used in vacuum smelting, vacuum drying, vacuum impregnation and large vacuum simulation testing,and so forth.
