JZB Roots vacuum pump

1. CZPT functions and doing work principle of the pump:
Product ZJ CZPT Booster Pump, also known as a Roots pump, is a volumetric pump.
It employs a pair of rotors, identical and in 8-figure with particular clearance between them
in the pump housing, rotating at the same pace in opposite instructions to complete
operate of suction and discharge of gas. The two rotors are supported by rolling bearings
in the conclude addresses of the pump, rotating at high velocity and are held at a
fixed relative place by a pair of timing gears. The stop clearance amongst rotors and
stop addresses are fixed by adjustable metallic shims amongst the bearing housings and the
conclude go over at the mounted stop, which makes certain a single-route enlargement of the rotor when
temperature rises throughout its operation.
4 sets of inner seals (also acknowledged as piston ring) in the two stop addresses avert lube oil
entering into the pump housing. The shaft seal at the entrance-conclude protect, also referred to as as
framework oil seal or shaft seal, prevents leakage of air into the pump housing.
In buy to reduce temperature of the pump, all models of pumps (assume the two
smallest models) are geared up with a gearbox cooler and entrance-end include cooler.
Energy is transmitted through 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
