Pump description:

Model ZJ Mechanical Booster Pump, also known as a Roots pump, is a volumetric pump.It employs a pair of rotors, identical and in 8-figure with certain clearance between them in the pump housing, rotating at the same speed in opposite directions to perform function of suction and discharge of gas. The two rotors are supported by rolling bearings in the end covers of the pump, rotating at high speed and are kept at a fixed relative position by a pair of timing gears. The end clearance between rotors and end covers are fixed by adjustable metal shims between the bearing housings and the end cover at the fixed end, which ensures one-direction expansion of the rotor when temperature rises during its operation.

Four sets of inner seals (also known as piston ring) in the two end covers prevent lube oil entering into the pump housing. The shaft seal at the front-end cover, also called as framework oil seal or shaft seal, prevents leakage of air into the pump housing.

In order to reduce temperature of the pump, all models of pumps (expect the two smallest models) are equipped with a gearbox cooler and front-end cover cooler.

Power is transmitted through a coupling or V-belt from the motor to the driving shaft of the pump and then through synchronizing gears to the driven shaft

Applications:
The main  advantage  of Roots  vacuum pump  is that  it can  operate  with high  pumping speed under  lower suction  pressures, however,  has to  be backed by  a backing  pump.Under  normal working conditions, it is  permissible to not add  by-pass pipes.Roots vacuum pump should not operate with a higher-pressure  difference than allowable,otherwise  overheating   and   overload  will   cause  damage   of  Roots   vacuum  pump.
Therefore, proper backing pump and necessary protection devices must be considered.Oil sealed mechanical  pump is usually  selected as   the fore   vacuum   pump.  Other   types   of backing   pumps   may   be   used   where    their requirement for ultimate vacuum is not too  strict. Particularly, when gas  pumped containing large amount of  vapor, water-ring vacuum pump  maybe   an  ideal   option  though   ultimate  vacuum achieved is on the low side.
