Operating principle and features:
The series HGL, HG pump is actually a type of single-stage and single-cylinder rotary piston vacuum pump. It truly is tremendously enhanced series H rotary piston pump and includes 4 patents; its basic capabilities have a good improvement.
Rotary piston vacuum pump is really a kind of vacuum manufacturing products suitable for pumping ordinary gases and condensable gases(whenever a gas ballast used). The pump have to be fitted with ideal equipment if gasoline is rich in oxygen, explosive, corrosive to ferrous metal, chemical reactive with vacuum pump oil.
Operation principle display 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 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 objective may very well be attained.
The series HGL, HG pump can be a backing pump when mixed with another substantial vacuum pump at the same time as operate singly. It is extensively utilized in vacuum smelting, vacuum drying, vacuum impregnation and high vacuum simulation testing,and so forth.
