ZJ Sequence Roots vacuum pump 

one. CZPT attributes and working principle of the pump:
Design 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 particular clearance in between them
in the pump housing, rotating at the same velocity in opposite directions to complete
function of suction and discharge of gasoline. The two rotors are supported by rolling bearings
in the conclude handles of the pump, rotating at substantial velocity and are stored at a
fastened relative situation by a pair of timing gears. The finish clearance between rotors and
end covers are set by adjustable steel shims between the bearing housings and the
conclude protect at the mounted finish, which assures 1-route enlargement of the rotor when
temperature rises in the course of its procedure.
4 sets of interior seals (also identified as piston ring) in the two finish covers prevent lube oil
getting into into the pump housing. The shaft seal at the entrance-stop include, also named as
framework oil seal or shaft seal, stops leakage of air into the pump housing.
In buy to minimize temperature of the pump, all versions of pumps (count on the two
smallest designs) are geared up with a gearbox cooler and front-conclude protect 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 pushed shaft
