Operating principle and attributes:
The series HGL, HG pump is really a form of single-stage and single-cylinder rotary piston vacuum pump. It really is greatly improved series H rotary piston pump and contains 4 patents; its common abilities have a great improvement.
Rotary piston vacuum pump is often a kind of vacuum production products appropriate for pumping ordinary gases and condensable gases(when a fuel ballast made use of). The pump have to be fitted with proper add-ons 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 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, to ensure that pumping objective may very well be accomplished.
The series HGL, HG pump might be a backing pump when combined with a different large vacuum pump as well as operate singly. It truly is widely used in vacuum smelting, vacuum drying, vacuum impregnation and high vacuum simulation testing,etc.
