JZB Roots vacuum pump

1. CZPT characteristics and working basic principle of the pump:
Design ZJ Mechanical Booster Pump, also identified as a Roots pump, is a volumetric pump.
It employs a pair of rotors, identical and in eight-determine with specific clearance in between them
in the pump housing, rotating at the identical pace in reverse instructions to perform
perform of suction and discharge of fuel. The two rotors are supported by rolling bearings
in the conclude covers of the pump, rotating at large pace and are stored at a
fastened relative position by a pair of timing gears. The stop clearance amongst rotors and
finish covers are fixed by adjustable metal shims between the bearing housings and the
conclude cover at the set end, which assures one-route enlargement of the rotor when
temperature rises for the duration of its operation.
4 sets of inner seals (also recognized as piston ring) in the two end handles avoid lube oil
coming into into the pump housing. The shaft seal at the front-finish include, also called as
framework oil seal or shaft seal, stops leakage of air into the pump housing.
In order to reduce temperature of the pump, all models of pumps (assume the two
smallest designs) are geared up with a gearbox cooler and entrance-finish cover cooler.
Electricity is transmitted via a coupling or V-belt from the motor to the driving shaft of
the pump and then by means of synchronizing gears to the pushed shaft
