Working principle and options:
The series HGL, HG pump is usually a type of single-stage and single-cylinder rotary piston vacuum pump. It is significantly improved series H rotary piston pump and consists of four patents; its standard abilities have a fantastic improvement.
Rotary piston vacuum pump is actually a type of vacuum manufacturing equipment appropriate for pumping ordinary gases and condensable gases(when a gas ballast utilised). The pump need to be fitted with proper accessories if gas is rich in oxygen, explosive, corrosive to ferrous metal, chemical reactive with vacuum pump oil.
Operation principle demonstrate in working 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, to ensure that pumping function may be attained.
The series HGL, HG pump is usually a backing pump when combined with a further higher vacuum pump likewise as operate singly. It truly is widely used in vacuum smelting, vacuum drying, vacuum impregnation and substantial vacuum simulation testing,etc.
