JZB Roots vacuum pump

one. CZPT characteristics and operating theory of the pump:
Model ZJ CZPT Booster Pump, also recognized as a Roots pump, is a volumetric pump.
It employs a pair of rotors, equivalent and in eight-figure with specified clearance amongst them
in the pump housing, rotating at the very same velocity in opposite directions to execute
purpose of suction and discharge of gasoline. The two rotors are supported by rolling bearings
in the stop handles of the pump, rotating at substantial speed and are retained at a
fixed relative situation by a pair of timing gears. The finish clearance amongst rotors and
stop covers are fastened by adjustable metal shims in between the bearing housings and the
end cover at the fastened stop, which makes certain one particular-path enlargement of the rotor when
temperature rises throughout its operation.
4 sets of interior seals (also identified as piston ring) in the two conclude handles stop lube oil
getting into into the pump housing. The shaft seal at the entrance-stop include, also called as
framework oil seal or shaft seal, stops leakage of air into the pump housing.
In order to minimize temperature of the pump, all models of pumps (anticipate the two
smallest versions) are outfitted with a gearbox cooler and entrance-conclude cover cooler.
Electrical power is transmitted via a coupling or V-belt from the motor to the driving shaft of
the pump and then through synchronizing gears to the driven shaft
