ZJ Series Roots vacuum pump
1. Development functions and working basic principle of the pump:
Model ZJ Mechanical Booster Pump, also known as a Roots pump, is a volumetric pump.
It employs a pair of rotors, identical and in 8-figure with specific clearance between them
in the pump housing, rotating at the very same speed in opposite instructions to carry out
function of suction and discharge of fuel. The two rotors are supported by rolling bearings
in the conclude covers of the pump, rotating at substantial speed and are retained at a
fixed relative placement by a pair of timing gears. The conclude clearance in between rotors and
finish handles are fixed by adjustable metal shims amongst the bearing housings and the
end include at the mounted conclude, which assures a single-path growth of the rotor when
temperature rises for the duration of its procedure.
Four sets of inner sea EPT (also recognized as piston ring) in the two conclude handles prevent lube oil
getting 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 order to lessen temperature of the pump, all mode EPT of pumps (expect the two
smalle EPT designs) are outfitted with a gearbox cooler and entrance-stop include cooler.
Electricity is transmitted through a coupling or V-belt from the motor to the driving shaft of
the pump and then by means of synchronizing gears to the driven shaft
