JZB Roots vacuum pump

one. CZPT features and functioning theory of the pump:
Model ZJ Mechanical Booster Pump, also identified as a Roots pump, is a volumetric pump.
It employs a pair of rotors, equivalent and in eight-figure with certain clearance amongst them
in the pump housing, rotating at the same velocity in opposite directions to carry out
function of suction and discharge of fuel. The two rotors are supported by rolling bearings
in the stop addresses of the pump, rotating at higher velocity and are held at a
fixed relative placement by a pair of timing gears. The conclude clearance in between rotors and
end covers are fastened by adjustable metal shims amongst the bearing housings and the
finish include at the fixed finish, which ensures a single-course growth of the rotor when
temperature rises for the duration of its procedure.
4 sets of internal seals (also known as piston ring) in the two finish addresses stop lube oil
coming into into the pump housing. The shaft seal at the front-stop protect, also called as
framework oil seal or shaft seal, prevents leakage of air into the pump housing.
In get to minimize temperature of the pump, all designs of pumps (expect the two
smallest designs) are outfitted with a gearbox cooler and front-stop include cooler.
Power 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
