ZJ Series Roots vacuum pump 

one. CZPT attributes and operating principle of the pump:
Model 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 among them
in the pump housing, rotating at the very same speed in opposite instructions 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 retained at a
fastened relative situation by a pair of timing gears. The stop clearance between rotors and
end covers are fixed by adjustable metal shims among the bearing housings and the
stop go over at the fixed finish, which guarantees a single-path expansion of the rotor when
temperature rises in the course of its operation.
4 sets of inner seals (also recognized as piston ring) in the two conclude covers avert lube oil
getting into into the pump housing. The shaft seal at the front-finish go over, also referred to as as
framework oil seal or shaft seal, prevents leakage of air into the pump housing.
In purchase to minimize temperature of the pump, all types of pumps (assume the two
smallest types) are outfitted with a gearbox cooler and entrance-finish go over cooler.
Power is transmitted through a coupling or V-belt from the motor to the driving shaft of
the pump and then via synchronizing gears to the pushed shaft
