Operating principle and features:
The series HGL, HG pump is really a kind of single-stage and single-cylinder rotary piston vacuum pump. It truly is considerably enhanced series H rotary piston pump and consists of four patents; its general capabilities possess a great improvement.
Rotary piston vacuum pump is actually a sort of vacuum manufacturing equipment ideal for pumping ordinary gases and condensable gases(whenever a gas ballast employed). The pump have to be fitted with appropriate add-ons if gas is wealthy in oxygen, explosive, corrosive to ferrous metal, chemical reactive with vacuum pump oil.
Operation principle demonstrate in operating principle graph: A rotary piston with slide valve across ecentric wheel driven by shaft in 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 purpose may be achieved.
The series HGL, HG pump could be a backing pump when mixed with yet another large vacuum pump as well as operate singly. It’s extensively used in vacuum smelting, vacuum drying, vacuum impregnation and large vacuum simulation testing,etc.
