ZJ Sequence Roots vacuum pump 

1. CZPT characteristics and working principle of the pump:
Model ZJ CZPT Booster Pump, also known as a Roots pump, is a volumetric pump.
It employs a pair of rotors, similar and in 8-determine with specific clearance between them
in the pump housing, rotating at the same speed in opposite instructions to carry out
function of suction and discharge of gas. The two rotors are supported by rolling bearings
in the stop covers of the pump, rotating at substantial pace and are retained at a
set relative situation by a pair of timing gears. The finish clearance between rotors and
finish covers are set by adjustable steel shims among the bearing housings and the
conclude protect at the fixed conclude, which makes certain one-path growth of the rotor when
temperature rises in the course of its procedure.
Four sets of interior seals (also known as piston ring) in the two finish covers stop lube oil
moving into into the pump housing. The shaft seal at the front-conclude cover, also referred to as as
framework oil seal or shaft seal, prevents leakage of air into the pump housing.
In purchase to reduce temperature of the pump, all versions of pumps (assume the two
smallest models) are geared up with a gearbox cooler and entrance-end cover cooler.
Electricity is transmitted through a coupling or V-belt from the motor to the driving shaft of
the pump and then through synchronizing gears to the driven shaft
