ZJ Sequence Roots vacuum pump 

one. CZPT features and working theory of the pump:
Model ZJ Mechanical Booster Pump, also recognized as a Roots pump, is a volumetric pump.
It employs a pair of rotors, equivalent and in eight-determine with particular clearance in between them
in the pump housing, rotating at the exact same pace in reverse directions to complete
perform of suction and discharge of fuel. The two rotors are supported by rolling bearings
in the finish addresses of the pump, rotating at large speed and are held at a
mounted relative place by a pair of timing gears. The end clearance in between rotors and
end addresses are set by adjustable metal shims amongst the bearing housings and the
conclude include at the fixed end, which makes certain a single-direction enlargement of the rotor when
temperature rises in the course of its operation.
4 sets of interior seals (also identified as piston ring) in the two end covers avoid lube oil
getting into into the pump housing. The shaft seal at the entrance-finish protect, also named as
framework oil seal or shaft seal, helps prevent leakage of air into the pump housing.
In buy to minimize temperature of the pump, all versions of pumps (assume the two
smallest designs) are outfitted with a gearbox cooler and front-conclude go over cooler.
Electrical 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 driven shaft
