JZB Roots vacuum pump

1. CZPT characteristics and working theory of the pump:
Product ZJ Mechanical Booster Pump, also identified as a Roots pump, is a volumetric pump.
It employs a pair of rotors, similar and in eight-figure with specific clearance between them
in the pump housing, rotating at the same pace in opposite instructions to execute
perform of suction and discharge of gas. The two rotors are supported by rolling bearings
in the stop addresses of the pump, rotating at large speed and are stored at a
fixed relative place by a pair of timing gears. The stop clearance amongst rotors and
end handles are mounted by adjustable steel shims amongst the bearing housings and the
end include at the set conclude, which guarantees one-path growth of the rotor when
temperature rises for the duration of its procedure.
Four sets of internal seals (also identified as piston ring) in the two stop addresses stop lube oil
entering into the pump housing. The shaft seal at the entrance-finish protect, also referred to as as
framework oil seal or shaft seal, helps prevent leakage of air into the pump housing.
In get to minimize temperature of the pump, all designs of pumps (expect the two
smallest models) are equipped with a gearbox cooler and entrance-end include cooler.
Power is transmitted through a coupling or V-belt from the motor to the driving shaft of
the pump and then via synchronizing gears to the pushed shaft
