Description of the micro annular gear pump

4.1

Operating principle of the micro annular gear pump

Micro annular gear pumps are positive displacement pumps. They contain two

rotors, bearing slightly eccentrically to each other; an externally toothed internal

rotor and an annular, internally toothed external rotor (see figure 3). Due to

their cycloid indenting, the rotors remain interlocked at any time, forming

during rotation a system of several sealed pumping chambers. As the rotors

revolve around their offset axis, the pumping chambers increase on the

induction (suction) side and simultaneously decrease on the delivery side of the

pump (see figure 4). A homogenous flow is generated between the kidney-like

inlet and outlet.

Operating principle of the micro annular gear pump

In the case of rotary displacement pumps, the delivered amount of liquid may

be easily calculated form the displacement volume

of the pump and the

number of revolutions of the rotor

. Displacement volume stands for the

volume of liquid that is moved within one revolution of the rotor. This

relationship is illustrated by the following formula:

Vol

⋅

The volumetric efficiency

Vol

shows the relationship between the actual and

the theoretical flow rate. The existing differences result from internal

movement of the liquid during the operation.
