ZJ Series Roots vacuum pump 

1. CZPT attributes and working basic principle of the pump:
Product ZJ Mechanical Booster Pump, also identified as a Roots pump, is a volumetric pump.
It employs a pair of rotors, equivalent and in 8-figure with specific clearance amongst them
in the pump housing, rotating at the very same velocity in opposite directions to complete
purpose of suction and discharge of gasoline. The two rotors are supported by rolling bearings
in the stop covers of the pump, rotating at high speed and are held at a
fixed relative placement by a pair of timing gears. The stop clearance amongst rotors and
stop covers are fixed by adjustable metallic shims between the bearing housings and the
conclude include at the mounted stop, which guarantees 1-path enlargement of the rotor when
temperature rises in the course of its procedure.
4 sets of interior seals (also acknowledged as piston ring) in the two finish addresses prevent lube oil
entering into the pump housing. The shaft seal at the front-finish protect, also referred to as as
framework oil seal or shaft seal, helps prevent leakage of air into the pump housing.
In order to reduce temperature of the pump, all types of pumps (assume the two
smallest versions) are equipped with a gearbox cooler and front-end protect cooler.
Electricity is transmitted through a coupling or V-belt from the motor to the driving shaft of
the pump and then via synchronizing gears to the pushed shaft
