ROTARY PISTON VACUUM PUMPS

Operating principle and capabilities:
The series HGL, HG pump is often a kind of single-stage and single-cylinder rotary piston vacuum pump. It can be greatly improved series H rotary piston pump and includes four patents; its basic abilities have a great improvement.
Rotary piston vacuum pump is really a type of vacuum production products suitable for pumping ordinary gases and condensable gases(whenever a fuel ballast utilized). The pump has to be fitted with suitable equipment if fuel is wealthy in oxygen, explosive, corrosive to ferrous metal, chemical reactive with vacuum pump oil.
Operation principle demonstrate in doing work 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 modified repetitively, so that pumping goal could possibly be attained.
The series HGL, HG pump is often a backing pump when mixed with one more high vacuum pump at the same time as operate singly. It’s broadly utilized in vacuum smelting, vacuum drying, vacuum impregnation and large vacuum simulation testing,etc.
