JZB Roots vacuum pump

1. CZPT characteristics and doing work theory of the pump:
Product ZJ Mechanical Booster Pump, also known as a Roots pump, is a volumetric pump.
It employs a pair of rotors, similar and in 8-figure with certain clearance in between them
in the pump housing, rotating at the very same velocity in reverse instructions to carry out
function of suction and discharge of fuel. The two rotors are supported by rolling bearings
in the finish addresses of the pump, rotating at high speed and are stored at a
set relative place by a pair of timing gears. The conclude clearance between rotors and
end addresses are fastened by adjustable metal shims between the bearing housings and the
conclude protect at the set stop, which guarantees one particular-path enlargement of the rotor when
temperature rises throughout its procedure.
4 sets of internal seals (also identified as piston ring) in the two end addresses prevent lube oil
getting into into the pump housing. The shaft seal at the entrance-conclude go over, also named as
framework oil seal or shaft seal, stops leakage of air into the pump housing.
In buy to lessen temperature of the pump, all versions of pumps (anticipate the two
smallest designs) are equipped with a gearbox cooler and entrance-conclude cover cooler.
Electricity is transmitted via 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
