Working principle and attributes:
The series HGL, HG pump is actually a type of single-stage and single-cylinder rotary piston vacuum pump. It’s considerably improved series H rotary piston pump and incorporates 4 patents; its general capabilities possess a fantastic improvement.
Rotary piston vacuum pump is really a kind of vacuum manufacturing equipment appropriate for pumping ordinary gases and condensable gases(whenever a fuel ballast employed). The pump have to be fitted with ideal add-ons if fuel is rich in oxygen, explosive, corrosive to ferrous metal, chemical reactive with vacuum pump oil.
Operation principle demonstrate in working 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 altered repetitively, to ensure that pumping goal might be attained.
The series HGL, HG pump could be a backing pump when mixed with a different large vacuum pump likewise as operate singly. It’s extensively utilized in vacuum smelting, vacuum drying, vacuum impregnation and large vacuum simulation testing,and so forth.
