1. CZPT characteristics and doing work 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, similar and in 8-determine with specific clearance between them
in the pump housing, rotating at the identical pace in opposite instructions to execute
operate of suction and discharge of gas. The two rotors are supported by rolling bearings
in the stop addresses of the pump, rotating at higher pace and are stored at a
mounted relative position by a pair of timing gears. The end clearance in between rotors and
finish covers are mounted by adjustable metallic shims in between the bearing housings and the
stop go over at the fixed finish, which makes certain one-route growth of the rotor when
temperature rises during its operation.
4 sets of internal seals (also recognized as piston ring) in the two conclude addresses avert lube oil
entering into the pump housing. The shaft seal at the entrance-stop go over, also named as
framework oil seal or shaft seal, prevents leakage of air into the pump housing.
In purchase to minimize temperature of the pump, all types of pumps (expect the two
smallest versions) are geared up with a gearbox cooler and front-end go over cooler.
Electricity is transmitted via a coupling or V-belt from the motor to the driving shaft of
the pump and then through synchronizing gears to the driven shaft
