ZJ Sequence Roots vacuum pump 

1. CZPT functions and doing work theory of the pump:
Model ZJ CZPT Booster Pump, also recognized as a Roots pump, is a volumetric pump.
It employs a pair of rotors, equivalent and in eight-determine with specific clearance among them
in the pump housing, rotating at the very same velocity in opposite instructions to carry out
operate of suction and discharge of fuel. The two rotors are supported by rolling bearings
in the conclude addresses of the pump, rotating at substantial velocity and are held at a
set relative place by a pair of timing gears. The stop clearance among rotors and
conclude handles are fastened by adjustable metal shims in between the bearing housings and the
finish cover at the mounted conclude, which guarantees one particular-course growth of the rotor when
temperature rises during its operation.
Four sets of interior seals (also known as piston ring) in the two end handles prevent lube oil
entering into the pump housing. The shaft seal at the front-stop include, also known as as
framework oil seal or shaft seal, helps prevent leakage of air into the pump housing.
In get to decrease temperature of the pump, all types of pumps (count on the two
smallest versions) are equipped with a gearbox cooler and entrance-finish protect cooler.
Electricity is transmitted through a coupling or V-belt from the motor to the driving shaft of
the pump and then by way of synchronizing gears to the pushed shaft
