FREMGANGSMAADE VED DRIFT AF EN VAESKEPUMPES PUMPEHJUL SAMT VAESKEPUMPE TIL UDOEVELSE AF FREMGANGSMAADEN |
| 摘要 |
The invention relates to a method of driving the impeller (5) of a liquid pump by means of a brushless a.c. motor (2) to which energy is supplied from a regulatable static inverter (6) operating at a frequency of 100-1000 Hz. The cavitation state of the impeller is sensed to set the inverter frequency at a value preventing cavitation. The inverter further relates to a pump for carrying out the method. |
