Working principle and functions:
The series HGL, HG pump is really a sort of single-stage and single-cylinder rotary piston vacuum pump. It really is significantly enhanced series H rotary piston pump and involves four patents; its common capabilities possess a excellent improvement.
Rotary piston vacuum pump is usually a sort of vacuum production equipment appropriate for pumping ordinary gases and condensable gases(when a gas ballast utilised). The pump has to be fitted with suitable accessories if gasoline is wealthy in oxygen, explosive, corrosive to ferrous metal, chemical reactive with vacuum pump oil.
Operation principle demonstrate in operating 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 transformed repetitively, so that pumping purpose could possibly be attained.
The series HGL, HG pump is usually a backing pump when combined with an additional high 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,etc.
