ZJ Series Roots vacuum pump 

one. CZPT functions and working theory of the pump:
Product ZJ CZPT Booster Pump, also acknowledged as a Roots pump, is a volumetric pump.
It employs a pair of rotors, identical and in eight-determine with specified clearance between them
in the pump housing, rotating at the exact same velocity in reverse instructions to execute
function of suction and discharge of gas. The two rotors are supported by rolling bearings
in the conclude handles of the pump, rotating at large speed and are retained at a
fastened relative position by a pair of timing gears. The finish clearance amongst rotors and
finish handles are mounted by adjustable metallic shims between the bearing housings and the
finish go over at the set end, which guarantees a single-route expansion of the rotor when
temperature rises for the duration of its procedure.
4 sets of interior seals (also recognized as piston ring) in the two end handles prevent lube oil
getting into into the pump housing. The shaft seal at the entrance-conclude cover, also called as
framework oil seal or shaft seal, prevents leakage of air into the pump housing.
In purchase to lessen temperature of the pump, all designs of pumps (anticipate the two
smallest versions) are geared up with a gearbox cooler and entrance-end go over cooler.
Electrical power is transmitted by way of a coupling or V-belt from the motor to the driving shaft of
the pump and then by way of synchronizing gears to the driven shaft
