ZJ Collection Roots vacuum pump 

1. CZPT features and working principle of the pump:
Design ZJ Mechanical Booster Pump, also recognized as a Roots pump, is a volumetric pump.
It employs a pair of rotors, identical and in 8-determine with specified clearance amongst them
in the pump housing, rotating at the identical speed in opposite directions to perform
purpose of suction and discharge of gasoline. The two rotors are supported by rolling bearings
in the finish covers of the pump, rotating at higher speed and are stored at a
set relative situation by a pair of timing gears. The finish clearance amongst rotors and
conclude addresses are set by adjustable steel shims in between the bearing housings and the
stop go over at the set stop, which guarantees 1-direction expansion of the rotor when
temperature rises for the duration of its procedure.
4 sets of inner seals (also known as piston ring) in the two end covers stop lube oil
getting into into the pump housing. The shaft seal at the front-stop include, also known as as
framework oil seal or shaft seal, helps prevent leakage of air into the pump housing.
In purchase to lessen temperature of the pump, all types of pumps (expect the two
smallest models) are equipped with a gearbox cooler and entrance-conclude cover cooler.
Electrical power is transmitted by means of a coupling or V-belt from the motor to the driving shaft of
the pump and then via synchronizing gears to the driven shaft
