ZJ Series Roots vacuum pump
one. Development functions and doing work basic principle of the pump:
Model ZJ Mechanical Booster Pump, also identified as a Roots pump, is a volumetric pump.
It employs a pair of rotors, similar and in 8-determine with specified clearance between them
in the pump housing, rotating at the very same pace in reverse directions to carry out
perform of suction and discharge of gasoline. The two rotors are supported by rolling bearings
in the stop addresses of the pump, rotating at higher speed and are retained at a
fastened relative place by a pair of timing gears. The finish clearance in between rotors and
end handles are fixed by adjustable metallic shims amongst the bearing housings and the
stop go over at the mounted conclude, which assures one particular-direction enlargement of the rotor when
temperature rises for the duration of its operation.
4 sets of internal sea EPT (also identified as piston ring) in the two finish addresses avert lube oil
entering into the pump housing. The shaft seal at the front-stop protect, also named as
framework oil seal or shaft seal, prevents leakage of air into the pump housing.
In get to lessen temperature of the pump, all manner EPT of pumps (expect the two
smalle EPT types) are equipped with a gearbox cooler and entrance-end go over cooler.
Power is transmitted via 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
