JZB Roots vacuum pump

1. CZPT functions and working principle of the pump:
Model ZJ CZPT Booster Pump, also acknowledged as a Roots pump, is a volumetric pump.
It employs a pair of rotors, similar and in 8-figure with specific clearance in between them
in the pump housing, rotating at the same pace in reverse directions to execute
operate of suction and discharge of fuel. The two rotors are supported by rolling bearings
in the conclude covers of the pump, rotating at substantial velocity and are stored at a
mounted relative situation by a pair of timing gears. The finish clearance amongst rotors and
finish handles are fastened by adjustable metallic shims amongst the bearing housings and the
finish cover at the mounted end, which guarantees a single-path enlargement of the rotor when
temperature rises throughout its procedure.
4 sets of internal seals (also acknowledged as piston ring) in the two conclude handles prevent lube oil
entering into the pump housing. The shaft seal at the front-conclude go over, also known as as
framework oil seal or shaft seal, prevents leakage of air into the pump housing.
In get to minimize temperature of the pump, all types of pumps (assume the two
smallest models) are equipped with a gearbox cooler and front-end go over cooler.
Electricity is transmitted through 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
