ZJ Sequence Roots vacuum pump 

1. CZPT attributes 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, identical and in eight-determine with certain clearance between them
in the pump housing, rotating at the exact same speed in reverse directions to carry out
operate of suction and discharge of gasoline. The two rotors are supported by rolling bearings
in the end handles of the pump, rotating at large pace and are held at a
set relative place by a pair of timing gears. The end clearance between rotors and
end addresses are fixed by adjustable steel shims between the bearing housings and the
stop cover at the mounted stop, which guarantees one-route growth of the rotor when
temperature rises for the duration of its procedure.
Four sets of internal seals (also known as piston ring) in the two end handles stop lube oil
entering into the pump housing. The shaft seal at the front-end cover, also referred to as as
framework oil seal or shaft seal, prevents leakage of air into the pump housing.
In order to minimize temperature of the pump, all versions of pumps (assume the two
smallest designs) are equipped with a gearbox cooler and entrance-finish include cooler.
Energy is transmitted via a coupling or V-belt from the motor to the driving shaft of
the pump and then by way of synchronizing gears to the pushed shaft
