ZJ Collection Roots vacuum pump
1. Design features and operating 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, similar and in 8-determine with specified clearance between them
in the pump housing, rotating at the same velocity in opposite directions to execute
function of suction and discharge of gas. The two rotors are supported by rolling bearings
in the conclude addresses of the pump, rotating at high pace and are held at a
fixed relative placement by a pair of timing gears. The stop clearance amongst rotors and
finish covers are fixed by adjustable steel shims in between the bearing housings and the
end protect at the fixed stop, which ensures a single-path expansion of the rotor when
temperature rises during its procedure.
4 sets of internal sea EPT (also recognized as piston ring) in the two end covers stop lube oil
entering into the pump housing. The shaft seal at the entrance-conclude go over, also known as as
framework oil seal or shaft seal, prevents leakage of air into the pump housing.
In order to minimize temperature of the pump, all manner EPT of pumps (assume the two
smalle EPT models) are geared up with a gearbox cooler and entrance-finish cover cooler.
Electrical power is transmitted through a coupling or V-belt from the motor to the driving shaft of
the pump and then by way of synchronizing gears to the pushed shaft
