Working principle and options:
The series HGL, HG pump can be a form of single-stage and single-cylinder rotary piston vacuum pump. It can be considerably improved series H rotary piston pump and includes 4 patents; its standard capabilities have a wonderful improvement.
Rotary piston vacuum pump is a kind of vacuum manufacturing tools ideal for pumping ordinary gases and condensable gases(whenever a gas ballast utilised). The pump have to be fitted with acceptable equipment if fuel is rich 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 modified repetitively, to ensure that pumping purpose might be achieved.
The series HGL, HG pump may be a backing pump when combined with another substantial vacuum pump as well as operate singly. It truly is broadly utilized in vacuum smelting, vacuum drying, vacuum impregnation and high vacuum simulation testing,etc.
