Vapor bulb used for NPSHR Measurement

The pump shall be run at constant capacity and speed with the suction conditions varied to produce cavitation. For higher values of NPSHA greater than NPSHR the values of head and power must remain constant. As suction pressure is reduced, a point is reached where the head and power curves break away from this trend, indicating the beginning of cavitation. Any change in performance, either a drop in head, power at a given capacity or a change in sound or vibration may be an indication of cavitation, but because of the difficulty in determining just when the change starts, a drop in head by 3 percent is accepted as evidence that cavitation is present. This criterion of acceptance is applied for NPSHR acceptance.
