Series Zjp Roots Vacuum Pumps - China
price: contact company for price
The series ZJP roots vacuum pump is with overflow valve.
The figure-of-
eight rotors are counter-rotating at a constant speed inside the pump
housing for suction and exhaust of gas.
Two rotors are supported by two
bearings and synchronized by a pair of gear, which ensure these two
rotors in certain relative positions.
They are near to one anther and
to the housing without actual contacting , so lubrication is unnecessary
in the working housing.
The carefully balance operating parts and high
precision bevel wheels ensure the pump be operated stably and
continuously under the condition of high-pressure difference.
Dynamic
seal part use our patent technology and imported oil seals.
The
vibration of shaft at the shaft seals is controlled to less than 0.02mm
against oil leaking.
A gravity valve is installed between the suction
and exhaust part of the pump.
The function of the gravity valve is as
follows, when the pressure difference between the suction and exhaust
part is over the weight of the valve, the valve opens
automatically, which makes the pressure difference always keep in a
fixed controllable valve, This valve is the allowable highest pressure
difference to ensure the pump work normally and so that in fact, the
roots vacuum pump with overflow valve is a kind of overload self-
protective pump.
Series ZJP roots vacuum pump with overflow valve has
substantially higher speed at relatively lower inlet pressure and it is
possessed overload self-prtotecive function .
The Pump is machined by
CNC manufacturing center.
'O' rings are used for sealing the pump body,
two sidecovers and two end covers.
All parts of pump have good
compatibility, so the overhaulis very easy.
The pump can't be operated
in dividually and should be used in connection with backing vacuum
pump.
The screw pump, oil seal pump and water ring pump are all
suitable as backing pump for Roots pump.
The Roots pump can beused to
pump a mass of condensable gases when it connected with a screw pumkp
or water ring pump.
