ZJ Collection Roots vacuum pump 

1. CZPT functions and operating theory of the pump:
Design ZJ CZPT Booster Pump, also identified as a Roots pump, is a volumetric pump.
It employs a pair of rotors, similar and in eight-figure with particular clearance in between them
in the pump housing, rotating at the exact same velocity in reverse instructions to perform
perform of suction and discharge of gasoline. The two rotors are supported by rolling bearings
in the stop addresses of the pump, rotating at high pace and are retained at a
fixed relative placement by a pair of timing gears. The stop clearance between rotors and
finish covers are fastened by adjustable steel shims between the bearing housings and the
finish cover at the mounted stop, which ensures a single-route growth of the rotor when
temperature rises for the duration of its operation.
4 sets of inner seals (also recognized as piston ring) in the two conclude addresses avoid lube oil
entering into the pump housing. The shaft seal at the entrance-stop include, also called as
framework oil seal or shaft seal, helps prevent leakage of air into the pump housing.
In order to reduce temperature of the pump, all versions of pumps (expect the two
smallest versions) are equipped with a gearbox cooler and front-stop include cooler.
Power is transmitted by way of a coupling or V-belt from the motor to the driving shaft of
the pump and then via synchronizing gears to the driven shaft
