ZJ Collection Roots vacuum pump 

1. CZPT functions and working principle of the pump:
Design ZJ CZPT Booster Pump, also identified as a Roots pump, is a volumetric pump.
It employs a pair of rotors, similar and in 8-determine with specified clearance amongst them
in the pump housing, rotating at the identical pace in reverse instructions to perform
function of suction and discharge of gas. The two rotors are supported by rolling bearings
in the finish handles of the pump, rotating at large speed and are stored at a
mounted relative situation by a pair of timing gears. The end clearance between rotors and
finish handles are fixed by adjustable steel shims among the bearing housings and the
conclude cover at the fixed end, which makes certain a single-route expansion of the rotor when
temperature rises during its operation.
4 sets of internal seals (also recognized as piston ring) in the two finish addresses avert lube oil
getting into into the pump housing. The shaft seal at the front-end cover, also named as
framework oil seal or shaft seal, prevents leakage of air into the pump housing.
In purchase to reduce temperature of the pump, all models of pumps (count on the two
smallest versions) are equipped with a gearbox cooler and front-finish include cooler.
Electrical power is transmitted by way 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 driven shaft
