Operating principle and functions:
The series HGL, HG pump can be a type of single-stage and single-cylinder rotary piston vacuum pump. It is actually greatly enhanced series H rotary piston pump and involves four patents; its common abilities have a excellent improvement.
Rotary piston vacuum pump is often a type of vacuum production tools suitable for pumping ordinary gases and condensable gases(when a gasoline ballast made use of). The pump needs to be fitted with proper accessories if gasoline is rich in oxygen, explosive, corrosive to ferrous metal, chemical reactive with vacuum pump oil.
Operation principle display in doing work 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 goal could be accomplished.
The series HGL, HG pump can be a backing pump when mixed with a different high vacuum pump also as operate singly. It truly is widely utilized in vacuum smelting, vacuum drying, vacuum impregnation and substantial vacuum simulation testing,and so on.
