ZJ Series Roots vacuum pump
1. Design characteristics and operating theory of the pump:
Model ZJ Mechanical Booster Pump, also acknowledged as a Roots pump, is a volumetric pump.
It employs a pair of rotors, identical and in 8-determine with specific clearance among them
in the pump housing, rotating at the same pace in opposite directions to execute
function of suction and discharge of gas. The two rotors are supported by rolling bearings
in the finish covers of the pump, rotating at high speed and are stored at a
fastened relative situation by a pair of timing gears. The stop clearance among rotors and
stop covers are mounted by adjustable metal shims amongst the bearing housings and the
conclude include at the mounted stop, which ensures one particular-path growth of the rotor when
temperature rises during its procedure.
4 sets of inner sea EPT (also known as piston ring) in the two finish handles stop lube oil
coming into into the pump housing. The shaft seal at the entrance-end protect, also called as
framework oil seal or shaft seal, helps prevent leakage of air into the pump housing.
In order to decrease temperature of the pump, all method EPT of pumps (anticipate the two
smalle EPT designs) are outfitted with a gearbox cooler and front-conclude cover cooler.
Energy 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
