Pumping Principle.
The pumping action of the rotary lobe pump principle is generated by the
contra-rotation of two pumping elements (rotors) within a chamber (rotorcase),
Fig 4. The shaft assemblies comprise of, the shaft support bearings and the
timing gears. The gears transfer the energy from the drive shaft to the driven
shaft, synchronising the rotors such that they rotate without contact with each
other.
As the rotors pass the suction port, (‘A’), the cavity increases creating a
pressure decrease, which induces the pumped medium to flow into the
rotorcase.
The pumped medium is carried around the rotorcase by the rotors, (‘B’) and
(‘C’), to the discharge side of the pump, (‘D’). Here the cavity decreases, and
the pumped medium is discharged from the rotorcase, (‘E’).
