ZJ Collection Roots vacuum pump 

1. CZPT features and operating basic principle of the pump:
Design ZJ Mechanical Booster Pump, also known as a Roots pump, is a volumetric pump.
It employs a pair of rotors, identical and in eight-figure with specified clearance among them
in the pump housing, rotating at the identical pace in reverse directions to execute
perform of suction and discharge of fuel. The two rotors are supported by rolling bearings
in the stop handles of the pump, rotating at high pace and are stored at a
set relative place by a pair of timing gears. The conclude clearance among rotors and
conclude covers are set by adjustable metal shims between the bearing housings and the
end include at the fastened conclude, which assures a single-direction expansion of the rotor when
temperature rises during its operation.
Four sets of inner seals (also recognized as piston ring) in the two end handles stop lube oil
moving into into the pump housing. The shaft seal at the entrance-finish protect, also known as as
framework oil seal or shaft seal, prevents leakage of air into the pump housing.
In get to decrease temperature of the pump, all designs of pumps (count on the two
smallest models) are equipped with a gearbox cooler and front-conclude protect cooler.
Power is transmitted by way of a coupling or V-belt from the motor to the driving shaft of
the pump and then by way of synchronizing gears to the driven shaft
