JZB Roots vacuum pump

1. CZPT functions and working theory of the pump:
Design ZJ CZPT Booster Pump, also recognized as a Roots pump, is a volumetric pump.
It employs a pair of rotors, identical and in 8-determine with certain clearance in between them
in the pump housing, rotating at the exact same pace in opposite instructions to complete
operate of suction and discharge of fuel. The two rotors are supported by rolling bearings
in the stop covers of the pump, rotating at high velocity and are held at a
fastened relative place by a pair of timing gears. The end clearance amongst rotors and
finish handles are set by adjustable metallic shims among the bearing housings and the
stop include at the mounted finish, which ensures a single-path growth of the rotor when
temperature rises during its procedure.
4 sets of interior seals (also known as piston ring) in the two end handles avert lube oil
entering into the pump housing. The shaft seal at the entrance-end include, also referred to as as
framework oil seal or shaft seal, helps prevent leakage of air into the pump housing.
In buy to decrease temperature of the pump, all versions of pumps (anticipate the two
smallest types) are outfitted with a gearbox cooler and front-finish protect cooler.
Power is transmitted by way of a coupling or V-belt from the motor to the driving shaft of
the pump and then via synchronizing gears to the driven shaft
