Working principle and functions:
The series HGL, HG pump is really a type of single-stage and single-cylinder rotary piston vacuum pump. It is drastically improved series H rotary piston pump and contains 4 patents; its basic abilities have a wonderful improvement.
Rotary piston vacuum pump is a type of vacuum manufacturing tools ideal for pumping ordinary gases and condensable gases(whenever a gasoline ballast made use of). The pump must be fitted with acceptable equipment if gasoline 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 altered repetitively, in order that pumping objective could possibly be attained.
The series HGL, HG pump is often a backing pump when mixed with one more substantial vacuum pump likewise as operate singly. It’s broadly used in vacuum smelting, vacuum drying, vacuum impregnation and higher vacuum simulation testing,etc.
