ROTARY PISTON VACUUM PUMPS


Working principle and functions:
The series HGL, HG pump is usually a kind of single-stage and single-cylinder rotary piston vacuum pump. It can be significantly improved series H rotary piston pump and consists of 4 patents; its common abilities have a good improvement.
Rotary piston vacuum pump is often a type of vacuum manufacturing gear appropriate for pumping ordinary gases and condensable gases(whenever a fuel ballast made use of). The pump has to be fitted with suitable equipment if fuel is wealthy 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 within 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 objective could possibly be accomplished.
The series HGL, HG pump may be a backing pump when combined with one more substantial vacuum pump also as operate singly. It really is extensively used in vacuum smelting, vacuum drying, vacuum impregnation and large vacuum simulation testing,and so on.
