JZB 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, identical and in 8-determine with certain clearance amongst 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 substantial velocity and are retained at a
mounted relative place by a pair of timing gears. The finish clearance in between rotors and
finish addresses are fastened by adjustable steel shims between the bearing housings and the
finish cover at the mounted finish, which makes certain a single-route growth of the rotor when
temperature rises during its operation.
Four sets of internal seals (also identified as piston ring) in the two finish covers stop lube oil
entering into the pump housing. The shaft seal at the front-conclude protect, also named as
framework oil seal or shaft seal, helps prevent leakage of air into the pump housing.
In get to minimize temperature of the pump, all designs of pumps (assume the two
smallest models) are equipped with a gearbox cooler and front-conclude cover cooler.
Energy is transmitted by way of a coupling or V-belt from the motor to the driving shaft of
the pump and then through synchronizing gears to the pushed shaft
