Flow rate and flow formula calculation of KCB gear pump
KCB type gear pump is suitable for conveying lubricating oil or other liquids with properties similar to lubricating oil that do not contain solid particles and fibers, are non corrosive, have a temperature not higher than 80 ℃, and a viscosity of 5 × 10-6~1.5 × 10-3m2/s (5-1500cSt).（1） Flow rate of gear pumpIn theory, the volume of oil carried to the discharge chamber should be equal to the working volume between teeth
2. The Qt per revolution should be the sum of the working volumes between all teeth of two gears.
3. It can be assumed that the working volume between teeth is equal to the effective volume of teeth.
4. Qt per revolution1) It is the sum of the working volume between teeth and the effective volume of teeth of a ge2) An annular volume with a radial width of 2m (where m is the modulus) that is approximately equal to the effective portion of the teeth sca（2） Flow formula for gear pumpWhen calculating the Qt of the pump using the above method, the value is relatively smallShould be multiplied by the correction factor K. The average Qt is:
Qt=K · D · 2m · B · n × 10-6L/minIn the formula: D - diameter of the dividing circle, mm;M - modulus, mm;B - tooth width, mm;N - rotational speed, r/min;K - Correction coefficient, generally ranging from 1.05 to 1.15.
