ZJ Collection Roots vacuum pump 

1. CZPT features and operating theory of the pump:
Model ZJ CZPT Booster Pump, also known as a Roots pump, is a volumetric pump.
It employs a pair of rotors, equivalent and in eight-determine with specific clearance between them
in the pump housing, rotating at the same velocity in reverse instructions to complete
operate of suction and discharge of fuel. The two rotors are supported by rolling bearings
in the finish addresses of the pump, rotating at substantial pace and are kept at a
set relative place by a pair of timing gears. The stop clearance in between rotors and
conclude covers are set by adjustable steel shims in between the bearing housings and the
finish cover at the mounted end, which makes certain a single-direction enlargement of the rotor when
temperature rises throughout its operation.
Four sets of internal seals (also acknowledged as piston ring) in the two conclude addresses prevent lube oil
getting into into the pump housing. The shaft seal at the entrance-finish cover, also named as
framework oil seal or shaft seal, prevents leakage of air into the pump housing.
In order to lessen temperature of the pump, all versions of pumps (count on the two
smallest types) are outfitted with a gearbox cooler and entrance-conclude go over cooler.
Power is transmitted by means of a coupling or V-belt from the motor to the driving shaft of
the pump and then via synchronizing gears to the pushed shaft
