JZB Roots vacuum pump

one. CZPT characteristics and working principle of the pump:
Design ZJ CZPT Booster Pump, also recognized as a Roots pump, is a volumetric pump.
It employs a pair of rotors, similar and in eight-determine with particular clearance between them
in the pump housing, rotating at the identical velocity in reverse directions to execute
perform of suction and discharge of gas. The two rotors are supported by rolling bearings
in the finish addresses of the pump, rotating at large velocity and are held at a
fixed relative placement by a pair of timing gears. The finish clearance between rotors and
stop addresses are set by adjustable metallic shims in between the bearing housings and the
finish cover at the fixed stop, which assures a single-course expansion of the rotor when
temperature rises throughout its operation.
4 sets of internal seals (also identified as piston ring) in the two conclude addresses prevent lube oil
coming into into the pump housing. The shaft seal at the front-end cover, also referred to as as
framework oil seal or shaft seal, stops leakage of air into the pump housing.
In get to minimize temperature of the pump, all types of pumps (assume the two
smallest models) are geared up with a gearbox cooler and front-finish cover cooler.
Power is transmitted through a coupling or V-belt from the motor to the driving shaft of
the pump and then by means of synchronizing gears to the driven shaft
