ZJ Collection Roots vacuum pump 

1. CZPT characteristics and doing work theory of the pump:
Product ZJ Mechanical Booster Pump, also known as a Roots pump, is a volumetric pump.
It employs a pair of rotors, similar and in 8-figure with particular clearance among them
in the pump housing, rotating at the very same pace in reverse directions to execute
function of suction and discharge of gas. The two rotors are supported by rolling bearings
in the finish handles of the pump, rotating at high speed and are held at a
set relative situation by a pair of timing gears. The stop clearance between rotors and
finish handles are fixed by adjustable metallic shims in between the bearing housings and the
end include at the fastened stop, which assures one particular-course growth of the rotor when
temperature rises throughout its procedure.
Four sets of interior seals (also known as piston ring) in the two end covers avoid 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, stops leakage of air into the pump housing.
In order to minimize temperature of the pump, all types of pumps (anticipate the two
smallest models) are equipped with a gearbox cooler and entrance-end include cooler.
Energy is transmitted via a coupling or V-belt from the motor to the driving shaft of
the pump and then by means of synchronizing gears to the driven shaft
