ZJ Collection Roots vacuum pump
one. Building features and functioning basic principle 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-determine with specified clearance in between them
in the pump housing, rotating at the exact same pace in opposite instructions to complete
operate of suction and discharge of gasoline. The two rotors are supported by rolling bearings
in the finish addresses of the pump, rotating at higher pace and are retained at a
mounted relative placement by a pair of timing gears. The stop clearance among rotors and
end addresses are fastened by adjustable steel shims amongst the bearing housings and the
finish protect at the set conclude, which ensures 1-path enlargement of the rotor when
temperature rises in the course of its operation.
4 sets of inner sea EPT (also acknowledged as piston ring) in the two stop covers avoid lube oil
getting into into the pump housing. The shaft seal at the entrance-stop go over, also known as as
framework oil seal or shaft seal, prevents leakage of air into the pump housing.
In get to minimize temperature of the pump, all method EPT of pumps (anticipate the two
smalle EPT types) are equipped with a gearbox cooler and front-end cover cooler.
Energy is transmitted by means of a coupling or V-belt from the motor to the driving shaft of
the pump and then by means of synchronizing gears to the pushed shaft
