JZB Roots vacuum pump

1. CZPT features and working basic principle of the pump:
Design ZJ Mechanical Booster Pump, also identified as a Roots pump, is a volumetric pump.
It employs a pair of rotors, equivalent and in 8-determine with specified clearance amongst them
in the pump housing, rotating at the identical pace in opposite directions to execute
function of suction and discharge of gasoline. The two rotors are supported by rolling bearings
in the finish handles of the pump, rotating at substantial speed and are held at a
set relative placement by a pair of timing gears. The conclude clearance among rotors and
finish handles are fixed by adjustable metallic shims between the bearing housings and the
end cover at the fixed conclude, which assures one particular-path expansion of the rotor when
temperature rises for the duration of its operation.
Four sets of inner seals (also acknowledged as piston ring) in the two conclude handles avoid lube oil
entering into the pump housing. The shaft seal at the front-conclude go over, also named as
framework oil seal or shaft seal, stops leakage of air into the pump housing.
In buy to minimize temperature of the pump, all models of pumps (expect the two
smallest designs) are outfitted with a gearbox cooler and front-stop include 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
