Working principle and attributes:
The series HGL, HG pump can be a form of single-stage and single-cylinder rotary piston vacuum pump. It really is considerably enhanced series H rotary piston pump and involves four patents; its standard abilities possess a great improvement.
Rotary piston vacuum pump is a kind of vacuum manufacturing gear appropriate for pumping ordinary gases and condensable gases(when a gasoline ballast utilised). The pump needs to be fitted with suitable add-ons if gasoline is wealthy in oxygen, explosive, corrosive to ferrous metal, chemical reactive with vacuum pump oil.
Operation principle present in working 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 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 altered repetitively, in order that pumping goal might be attained.
The series HGL, HG pump can be a backing pump when combined with another high vacuum pump likewise as operate singly. It can be broadly used in vacuum smelting, vacuum drying, vacuum impregnation and large vacuum simulation testing,and so forth.
