JZB Roots vacuum pump

one. CZPT characteristics and doing work theory of the pump:
Design ZJ CZPT Booster Pump, also identified as a Roots pump, is a volumetric pump.
It employs a pair of rotors, similar and in eight-figure with particular clearance amongst them
in the pump housing, rotating at the very same velocity in opposite instructions to complete
purpose of suction and discharge of gasoline. The two rotors are supported by rolling bearings
in the end addresses of the pump, rotating at higher speed and are retained at a
fastened relative position by a pair of timing gears. The stop clearance among rotors and
finish addresses are set by adjustable metallic shims in between the bearing housings and the
stop go over at the set end, which ensures one-direction expansion of the rotor when
temperature rises for the duration of its operation.
Four sets of internal seals (also identified as piston ring) in the two finish covers stop lube oil
entering into the pump housing. The shaft seal at the entrance-stop include, also referred to as as
framework oil seal or shaft seal, stops leakage of air into the pump housing.
In buy to lessen temperature of the pump, all versions of pumps (expect the two
smallest models) are equipped with a gearbox cooler and entrance-conclude go over cooler.
Electricity is transmitted by way of a coupling or V-belt from the motor to the driving shaft of
the pump and then through synchronizing gears to the pushed shaft
