Working principle and options:
The series HGL, HG pump can be a form of single-stage and single-cylinder rotary piston vacuum pump. It is significantly improved series H rotary piston pump and involves 4 patents; its standard abilities possess a fantastic improvement.
Rotary piston vacuum pump is actually a kind of vacuum production gear appropriate for pumping ordinary gases and condensable gases(whenever a fuel ballast made use of). The pump need to be fitted with appropriate add-ons if gas is rich in oxygen, explosive, corrosive to ferrous metal, chemical reactive with vacuum pump oil.
Operation principle present in functioning 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 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 modified repetitively, so that pumping function may be attained.
The series HGL, HG pump could be a backing pump when combined with a further high vacuum pump also as operate singly. It can be widely utilized in vacuum smelting, vacuum drying, vacuum impregnation and higher vacuum simulation testing,and so on.
