JZB Roots vacuum pump

one. CZPT characteristics and working 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, equivalent and in 8-determine with specific clearance amongst them
in the pump housing, rotating at the very same speed 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 large pace and are kept at a
set relative place by a pair of timing gears. The finish clearance among rotors and
end addresses are mounted by adjustable steel shims in between the bearing housings and the
conclude go over at the mounted end, which guarantees one particular-course growth of the rotor when
temperature rises during its operation.
Four sets of interior seals (also known as piston ring) in the two end covers stop lube oil
getting into into the pump housing. The shaft seal at the entrance-conclude include, also called as
framework oil seal or shaft seal, helps prevent leakage of air into the pump housing.
In get to lessen temperature of the pump, all versions of pumps (assume the two
smallest designs) are outfitted with a gearbox cooler and front-finish go over 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 way of synchronizing gears to the driven shaft
