ZJ Collection Roots vacuum pump 

one. CZPT characteristics and operating principle of the pump:
Model ZJ Mechanical Booster Pump, also recognized as a Roots pump, is a volumetric pump.
It employs a pair of rotors, equivalent and in 8-determine with particular clearance between them
in the pump housing, rotating at the exact same velocity in reverse directions to execute
function of suction and discharge of gas. The two rotors are supported by rolling bearings
in the finish addresses of the pump, rotating at substantial pace and are held at a
fixed relative placement by a pair of timing gears. The stop clearance amongst rotors and
finish covers are fixed by adjustable metallic shims amongst the bearing housings and the
conclude cover at the fastened stop, which guarantees a single-route enlargement of the rotor when
temperature rises during its procedure.
Four sets of internal seals (also acknowledged as piston ring) in the two finish covers avoid lube oil
coming into into the pump housing. The shaft seal at the entrance-end protect, also known as as
framework oil seal or shaft seal, helps prevent leakage of air into the pump housing.
In buy to minimize temperature of the pump, all designs of pumps (assume the two
smallest models) are equipped with a gearbox cooler and front-end go over cooler.
Power is transmitted by way of a coupling or V-belt from the motor to the driving shaft of
the pump and then by way of synchronizing gears to the driven shaft
