ZJ Series Roots vacuum pump 

one. CZPT characteristics and operating theory of the pump:
Model ZJ Mechanical Booster Pump, also known as a Roots pump, is a volumetric pump.
It employs a pair of rotors, equivalent and in 8-figure with specified clearance among them
in the pump housing, rotating at the identical pace in opposite instructions to execute
function of suction and discharge of fuel. The two rotors are supported by rolling bearings
in the end covers of the pump, rotating at higher velocity and are stored at a
mounted relative situation by a pair of timing gears. The finish clearance in between rotors and
stop covers are fastened by adjustable steel shims among the bearing housings and the
conclude include at the mounted conclude, which assures 1-course enlargement of the rotor when
temperature rises for the duration of its procedure.
4 sets of inner seals (also recognized as piston ring) in the two finish addresses avert lube oil
entering into the pump housing. The shaft seal at the entrance-conclude cover, 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 designs of pumps (count on the two
smallest designs) are outfitted with a gearbox cooler and entrance-stop go over cooler.
Power 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 pushed shaft
