ZJ Collection Roots vacuum pump 

one. CZPT features and operating theory of the pump:
Design ZJ CZPT Booster Pump, also known as a Roots pump, is a volumetric pump.
It employs a pair of rotors, similar and in 8-determine with particular clearance among them
in the pump housing, rotating at the same pace in reverse directions to complete
function of suction and discharge of fuel. The two rotors are supported by rolling bearings
in the stop handles of the pump, rotating at substantial pace and are held at a
mounted relative placement by a pair of timing gears. The conclude clearance among rotors and
end covers are fixed by adjustable steel shims amongst the bearing housings and the
stop protect at the mounted end, which guarantees one particular-course expansion of the rotor when
temperature rises for the duration of its operation.
Four sets of interior seals (also acknowledged as piston ring) in the two end addresses avoid lube oil
entering into the pump housing. The shaft seal at the front-finish include, also called as
framework oil seal or shaft seal, helps prevent leakage of air into the pump housing.
In buy to decrease temperature of the pump, all types of pumps (assume the two
smallest models) are equipped with a gearbox cooler and entrance-finish include 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
