遠心ポンプの媒体変更による影響

2019-08-15View Original

Thread Content

古い遠心ポンプを再利用する場合、元の媒体の密度は1だったが、現在は1.3になっている。流量や揚程は変わらないが、動力はどう変わり、負荷はどのように計算・評価すればよいか
Reply #22019-08-15
軸動力=流量×揚程×比重/367/効率
Reply #32019-08-15
粘度の変化が小さい場合は、出力に1.3を直接掛ければよい
Reply #42019-08-15
粘度を10から16に上げると、どのような影響が出ますか?
Reply #52019-08-15
この影響は小さく無視でき、粘度が20効率を超えなければ、流量や揚程の修正は不要です
