Operating principle and functions:
The series HGL, HG pump is really a sort of single-stage and single-cylinder rotary piston vacuum pump. It really is considerably improved series H rotary piston pump and involves 4 patents; its basic abilities have a wonderful improvement.
Rotary piston vacuum pump is often a type of vacuum manufacturing gear suitable for pumping ordinary gases and condensable gases(whenever a fuel ballast utilised). The pump have to be fitted with ideal accessories if fuel is wealthy 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 altered repetitively, to ensure that pumping goal can be accomplished.
The series HGL, HG pump could be a backing pump when mixed with yet another large vacuum pump also as operate singly. It can be extensively utilized in vacuum smelting, vacuum drying, vacuum impregnation and substantial vacuum simulation testing,and so on.
