ZJ Sequence Roots vacuum pump 

1. CZPT functions and functioning principle of the pump:
Model ZJ Mechanical Booster Pump, also identified as a Roots pump, is a volumetric pump.
It employs a pair of rotors, identical and in eight-figure with certain clearance among them
in the pump housing, rotating at the same speed in opposite directions to carry out
function of suction and discharge of gas. The two rotors are supported by rolling bearings
in the end covers of the pump, rotating at large speed and are kept at a
mounted relative position by a pair of timing gears. The stop clearance in between rotors and
conclude addresses are fastened by adjustable metallic shims in between the bearing housings and the
finish protect at the fastened conclude, which guarantees a single-direction growth of the rotor when
temperature rises for the duration of its operation.
Four sets of interior seals (also acknowledged as piston ring) in the two finish covers prevent lube oil
moving into into the pump housing. The shaft seal at the entrance-stop go over, also known as as
framework oil seal or shaft seal, helps prevent leakage of air into the pump housing.
In order to lessen temperature of the pump, all types of pumps (count on the two
smallest versions) are equipped with a gearbox cooler and front-end cover cooler.
Electrical power is transmitted via a coupling or V-belt from the motor to the driving shaft of
the pump and then by means of synchronizing gears to the pushed shaft
