ROTARY PISTON VACUUM PUMPS

Working principle and options:
The series HGL, HG pump is often a sort of single-stage and single-cylinder rotary piston vacuum pump. It can be greatly enhanced series H rotary piston pump and involves four patents; its general abilities have a excellent improvement.
Rotary piston vacuum pump can be a sort of vacuum manufacturing gear appropriate for pumping ordinary gases and condensable gases(whenever a fuel ballast utilised). The pump have to be fitted with ideal equipment if gas is wealthy in oxygen, explosive, corrosive to ferrous metal, chemical reactive with vacuum pump oil.
Operation principle show in operating 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 altered repetitively, to ensure pumping purpose might be accomplished.
The series HGL, HG pump might be a backing pump when combined with another higher vacuum pump at the same time as operate singly. It is extensively used in vacuum smelting, vacuum drying, vacuum impregnation and high vacuum simulation testing,and so forth.
