- 開油圧回路で動作する遠心ポンプの回転速度を制御する方法であって、
ポンプ制御システムのコントローラは、実際の回転速度と同様に、所望の揚程および実際の揚程を考慮して、ポンプ駆動の所望の回転速度を決定し、
前記所望の回転速度を計算するために、前記コントローラは、測地高度を記述するための補正パラメータを考慮する、
ことを特徴とする、方法。 - 前記コントローラは、設定値を決定するための基礎として少なくとも親和性の法則の要素を使用し、特に、前記設定値の計算のために前記回転速度と前記揚程との間の二次関係を仮定する、
ことを特徴とする、請求項1に記載の方法。 - 前記コントローラは、前記所望の回転速度と前記所望の揚程との間の二次関係、および前記実際の回転速度と前記実際の揚程との間の二次関係の比から前記所望の回転速度を決定する、
ことを特徴とする、請求項2に記載の方法。 - 前記二次関係によって定義される放物線は、前記補正パラメータによって座標原点に変位される、
ことを特徴とする、請求項2または3に記載の方法。 - 前記補正パラメータの値は、ポンプの動作中に決定される、
ことを特徴とする、請求項1から4のいずれか1項に記載の方法。 - 前記ポンプの試運転時に、前記補正パラメータに既知の初期値、特にゼロの値が割り当てられる、
ことを特徴とする、請求項5に記載の方法。 - 前記補正パラメータは、ポンプの動作中に、制御誤差、特に前記所望の揚程と前記実際の揚程との間の差から導出される、
ことを特徴とする、請求項5または6に記載の方法。 - 前記補正パラメータは、式1を使用して計算される、
ことを特徴とする、請求項7に記載の方法。
- 前記補正パラメータは、初期試運転時のポンプの動作中に、および/または定期的に周期的な間隔で、および/またはランダムな間隔で決定される、
ことを特徴とする、請求項5から7のいずれか1項に記載の方法。 - 請求項1から9のいずれか1項に記載の方法を実行するためのポンプ制御システムを備えた遠心ポンプ。
