Description
を満たすように決定してもよい。
必要十分な吐出量の精度が得られる場合には、インペラ用シャフト10もロッド9と同様に分割し、湯面接触部分をジョイントスリーブにより接続してもよい。
Δh=a×N2+b (ただしa、bは実数) …(1)
を満たすように決定する。
Δhs=V/S [mm]
で与えられる。そしてkショット目の高さ変化量Δhkは、
Δhk=k×Δhs [mm]
となる。表面積Sおよび吐出量Vはいずれも既知であるから、制御部120は各ショットにおける湯面高さhおよび変化量Δhをトレースすることができる。そして変化量Δhに応じてモータの回転数を補正する。式(1)におけるパラメータa、bは、マグネシウム給湯装置100を用いて実験することにより最適化することができる。
