Claims (2)
- 渦巻きポンプの運転制御方法において、ポンプ起動時の吐出側水位を水位センサにより検出しその検出信号をポンプモータの制御装置へ入力し、該入力信号に基づき回転数が選択され、ポンプの実運転出力が過負荷とならないようにポンプの運転出力を制限するために設定された設定出力と同等で且つポンプの実回転数が吐出揚程不足とならないように該実回転数を増速させるために設定された設定回転数と同等となるポンプ運転点を境として、ポンプの実運転出力が設定出力以下で且つ実回転数が設定回転数と同等のときは、該実回転数の増速を優先させて該実回転数を設定回転数と同等に継続させる回転数設定制御が選択されて高揚程向けの運転が行われ、また、ポンプの実運転出力が設定出力と同等で且つ実回転数が設定回転数以下のときは、該実回転数を増・減速させて該実運転出力を設定出力と同等に継続させる軸出力設定制御が選択されて低揚程向けの運転が行われることを特徴とする、渦巻きポンプの運転制御方法。
- 水位センサからの入力に基づき回転数が選択され、吐出側水位が予め定められたポンプの締切運転水位に近づくに従い、段階的に所定の設定回転数に切り替え増速されて吐出揚程を増大させることを特徴とする、請求項1記載の渦巻きポンプの運転制御方法。
