Working principle and capabilities:
The series HGL, HG pump is usually a form of single-stage and single-cylinder rotary piston vacuum pump. It really is considerably improved series H rotary piston pump and contains 4 patents; its standard abilities have a excellent improvement.
Rotary piston vacuum pump is actually a sort of vacuum production equipment ideal for pumping ordinary gases and condensable gases(when a fuel ballast made use of). The pump needs to be fitted with suitable accessories if gasoline is rich in oxygen, explosive, corrosive to ferrous metal, chemical reactive with vacuum pump oil.
Operation principle present in doing work principle graph: A rotary piston with slide valve across ecentric wheel driven by shaft in 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 changed repetitively, so that pumping goal might be achieved.
The series HGL, HG pump might be a backing pump when mixed with another higher vacuum pump as well as operate singly. It is actually extensively utilized in vacuum smelting, vacuum drying, vacuum impregnation and substantial vacuum simulation testing,and so on.
