one. CZPT attributes and working principle of the pump:
Product ZJ CZPT Booster Pump, also known as a Roots pump, is a volumetric pump.
It employs a pair of rotors, identical and in eight-determine with particular clearance among them
in the pump housing, rotating at the identical velocity in reverse instructions to perform
operate of suction and discharge of gas. The two rotors are supported by rolling bearings
in the finish handles of the pump, rotating at high pace and are stored at a
set relative placement by a pair of timing gears. The end clearance between rotors and
finish handles are fixed by adjustable metallic shims in between the bearing housings and the
stop protect at the mounted end, which assures 1-course expansion of the rotor when
temperature rises during its procedure.
4 sets of internal seals (also identified as piston ring) in the two stop handles prevent lube oil
entering into the pump housing. The shaft seal at the entrance-stop go over, also named as
framework oil seal or shaft seal, stops leakage of air into the pump housing.
In purchase to lessen temperature of the pump, all versions of pumps (expect the two
smallest versions) are outfitted with a gearbox cooler and entrance-conclude protect cooler.
Power is transmitted via 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
