JZB Roots vacuum pump

1. CZPT functions and operating principle of the pump:
Design ZJ Mechanical Booster Pump, also known as a Roots pump, is a volumetric pump.
It employs a pair of rotors, equivalent and in 8-determine with particular clearance in between them
in the pump housing, rotating at the same speed in opposite directions to complete
operate of suction and discharge of gasoline. The two rotors are supported by rolling bearings
in the stop covers of the pump, rotating at substantial pace and are held at a
fastened relative place by a pair of timing gears. The stop clearance between rotors and
end covers are fastened by adjustable metallic shims amongst the bearing housings and the
stop protect at the fixed finish, which makes certain one-route expansion of the rotor when
temperature rises throughout its procedure.
4 sets of internal seals (also identified as piston ring) in the two stop addresses stop lube oil
moving into into the pump housing. The shaft seal at the front-stop go over, also known as as
framework oil seal or shaft seal, helps prevent leakage of air into the pump housing.
In buy to decrease temperature of the pump, all models of pumps (assume the two
smallest models) are geared up with a gearbox cooler and entrance-stop cover cooler.
Electricity is transmitted via a coupling or V-belt from the motor to the driving shaft of
the pump and then by way of synchronizing gears to the pushed shaft
