Operating principle and functions:
The series HGL, HG pump is often a form of single-stage and single-cylinder rotary piston vacuum pump. It really is greatly improved series H rotary piston pump and involves 4 patents; its common capabilities possess a fantastic improvement.
Rotary piston vacuum pump is actually a kind of vacuum production products suitable for pumping ordinary gases and condensable gases(when a gas ballast utilized). The pump need to be fitted with ideal equipment if gasoline is wealthy 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 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 changed repetitively, in order that pumping function may be accomplished.
The series HGL, HG pump can be a backing pump when combined with yet another high vacuum pump as well as operate singly. It really is widely utilized in vacuum smelting, vacuum drying, vacuum impregnation and high vacuum simulation testing,and so forth.
