ZJ Sequence Roots vacuum pump 

1. CZPT functions and operating theory of the pump:
Design ZJ Mechanical Booster Pump, also recognized as a Roots pump, is a volumetric pump.
It employs a pair of rotors, identical and in 8-determine with specified clearance in between them
in the pump housing, rotating at the identical pace in opposite instructions to complete
purpose of suction and discharge of gasoline. The two rotors are supported by rolling bearings
in the stop covers of the pump, rotating at higher speed and are kept at a
set relative place by a pair of timing gears. The end clearance amongst rotors and
end covers are set by adjustable steel shims among the bearing housings and the
stop cover at the fixed end, which guarantees one particular-route enlargement of the rotor when
temperature rises in the course of its procedure.
4 sets of internal seals (also identified as piston ring) in the two finish handles prevent lube oil
getting into into the pump housing. The shaft seal at the entrance-end go over, also known as as
framework oil seal or shaft seal, helps prevent leakage of air into the pump housing.
In get to lessen temperature of the pump, all designs of pumps (count on the two
smallest designs) are geared up with a gearbox cooler and entrance-end protect cooler.
Power is transmitted through a coupling or V-belt from the motor to the driving shaft of
the pump and then through synchronizing gears to the driven shaft
