JZB Roots vacuum pump
one. Design functions and operating 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, equivalent and in 8-determine with certain clearance amongst them
in the pump housing, rotating at the same pace in reverse instructions to complete
perform of suction and discharge of gasoline. The two rotors are supported by rolling bearings
in the end covers of the pump, rotating at high velocity and are retained at a
fastened relative situation by a pair of timing gears. The conclude clearance in between rotors and
conclude handles are fastened by adjustable steel shims among the bearing housings and the
conclude go over at the mounted finish, which guarantees a single-direction enlargement of the rotor when
temperature rises in the course of its operation.
Four sets of internal sea EPT (also identified as piston ring) in the two conclude covers prevent lube oil
getting into into the pump housing. The shaft seal at the front-stop include, also called as
framework oil seal or shaft seal, prevents leakage of air into the pump housing.
In buy to lessen temperature of the pump, all manner EPT of pumps (anticipate the two
smalle EPT versions) are geared up with a gearbox cooler and front-stop go over cooler.
Energy is transmitted via a coupling or V-belt from the motor to the driving shaft of
the pump and then via synchronizing gears to the pushed shaft
