ZJ Series Roots vacuum pump 

1. CZPT functions and operating theory of the pump:
Design ZJ Mechanical Booster Pump, also acknowledged as a Roots pump, is a volumetric pump.
It employs a pair of rotors, similar and in 8-determine with certain clearance between them
in the pump housing, rotating at the exact same pace in opposite directions to complete
function of suction and discharge of gas. The two rotors are supported by rolling bearings
in the finish handles of the pump, rotating at substantial speed and are kept at a
fixed relative situation by a pair of timing gears. The stop clearance between rotors and
conclude handles are mounted by adjustable metallic shims amongst the bearing housings and the
conclude include at the mounted conclude, which ensures 1-path enlargement of the rotor when
temperature rises for the duration of its procedure.
Four sets of interior seals (also recognized as piston ring) in the two stop addresses prevent lube oil
entering into the pump housing. The shaft seal at the entrance-finish protect, also referred to as as
framework oil seal or shaft seal, helps prevent leakage of air into the pump housing.
In purchase to reduce temperature of the pump, all designs of pumps (expect the two
smallest models) are outfitted with a gearbox cooler and front-finish 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 driven shaft
