Operating principle and functions:
The series HGL, HG pump is actually a sort of single-stage and single-cylinder rotary piston vacuum pump. It really is enormously enhanced series H rotary piston pump and involves 4 patents; its standard abilities have a wonderful improvement.
Rotary piston vacuum pump is often a type of vacuum manufacturing gear suitable for pumping ordinary gases and condensable gases(whenever a fuel ballast utilised). The pump need to be fitted with appropriate accessories if fuel is wealthy in oxygen, explosive, corrosive to ferrous metal, chemical reactive with vacuum pump oil.
Operation principle present in functioning 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 altered repetitively, to ensure that pumping goal can be accomplished.
The series HGL, HG pump could be a backing pump when mixed with yet another large vacuum pump also as operate singly. It is actually extensively used in vacuum smelting, vacuum drying, vacuum impregnation and substantial vacuum simulation testing,and so on.
