ZJ Sequence Roots vacuum pump
1. Development functions and working principle of the pump:
Model ZJ Mechanical Booster Pump, also acknowledged as a Roots pump, is a volumetric pump.
It employs a pair of rotors, identical and in 8-figure with particular clearance among them
in the pump housing, rotating at the identical speed in reverse directions to execute
perform of suction and discharge of fuel. The two rotors are supported by rolling bearings
in the conclude addresses of the pump, rotating at large pace and are kept at a
mounted relative position by a pair of timing gears. The stop clearance in between rotors and
stop addresses are fixed by adjustable steel shims between the bearing housings and the
conclude cover at the set conclude, which assures 1-direction expansion of the rotor when
temperature rises during its procedure.
4 sets of interior sea EPT (also known as piston ring) in the two end covers avert lube oil
moving into into the pump housing. The shaft seal at the front-end go over, also named as
framework oil seal or shaft seal, helps prevent leakage of air into the pump housing.
In buy to lessen temperature of the pump, all method EPT of pumps (assume the two
smalle EPT types) are geared up with a gearbox cooler and entrance-end protect cooler.
Electricity is transmitted by way of a coupling or V-belt from the motor to the driving shaft of
the pump and then by means of synchronizing gears to the pushed shaft
