ZJ Collection Roots vacuum pump 

1. CZPT characteristics and working theory of the pump:
Design ZJ CZPT Booster Pump, also identified as a Roots pump, is a volumetric pump.
It employs a pair of rotors, identical and in 8-figure with particular clearance among them
in the pump housing, rotating at the identical pace in opposite directions to perform
purpose of suction and discharge of fuel. The two rotors are supported by rolling bearings
in the stop addresses of the pump, rotating at large pace and are stored at a
fixed relative situation by a pair of timing gears. The conclude clearance between rotors and
conclude handles are set by adjustable metallic shims between the bearing housings and the
end protect at the fixed conclude, which ensures one particular-course enlargement of the rotor when
temperature rises throughout its procedure.
Four sets of interior seals (also known as piston ring) in the two finish handles stop lube oil
moving into 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 purchase to reduce temperature of the pump, all models of pumps (expect the two
smallest versions) are geared up with a gearbox cooler and entrance-conclude protect cooler.
Electrical power is transmitted through a coupling or V-belt from the motor to the driving shaft of
the pump and then through synchronizing gears to the pushed shaft
