JZB Roots vacuum pump

1. CZPT features and functioning basic principle of the pump:
Model ZJ Mechanical Booster Pump, also identified as a Roots pump, is a volumetric pump.
It employs a pair of rotors, similar and in 8-figure with specified clearance between them
in the pump housing, rotating at the same speed in reverse directions to execute
perform of suction and discharge of gasoline. The two rotors are supported by rolling bearings
in the finish addresses of the pump, rotating at high pace and are retained at a
fixed relative place by a pair of timing gears. The conclude clearance between rotors and
conclude covers are mounted by adjustable metallic shims between the bearing housings and the
conclude go over at the fastened end, which ensures a single-route enlargement of the rotor when
temperature rises during its operation.
Four sets of interior seals (also acknowledged as piston ring) in the two conclude handles avoid lube oil
moving into into the pump housing. The shaft seal at the front-stop protect, also named as
framework oil seal or shaft seal, prevents leakage of air into the pump housing.
In buy to minimize temperature of the pump, all versions of pumps (expect the two
smallest types) are geared up with a gearbox cooler and entrance-finish cover cooler.
Power is transmitted by means of a coupling or V-belt from the motor to the driving shaft of
the pump and then via synchronizing gears to the pushed shaft
