ROTARY PISTON VACUUM PUMPS

Operating principle and functions:
The series HGL, HG pump is often a kind of single-stage and single-cylinder rotary piston vacuum pump. It really is significantly improved series H rotary piston pump and incorporates 4 patents; its common capabilities possess a excellent improvement.
Rotary piston vacuum pump is actually a kind of vacuum production equipment suitable for pumping ordinary gases and condensable gases(when a gas ballast utilized). The pump need to be fitted with ideal equipment if gasoline is wealthy 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 within the housing. Piston pole can slide and swing freely in arch track. The whole pump chamber is divided into chamber A and chamber B by piston. When shaft rotates the volume of chamber A and chamber B are changed repetitively, in order that pumping function may very well be accomplished.
The series HGL, HG pump can be a backing pump when combined with one more high vacuum pump as well as operate singly. It really is extensively used in vacuum smelting, vacuum drying, vacuum impregnation and higher vacuum simulation testing,and so forth.
