The start level and stop level must be as close as possible to ? 啟停液位應(yīng)盡可能滿足 ?design the tank size by optimizing the effective volume ?通過優(yōu)化有效容積設(shè)計(jì)井筒尺寸 At least at the top of the motor 最小到電機(jī)的頂部 Effective Volume 有效容積 ?2 Start level 啟泵液位 Stop level 停泵液位 ?2 Effective Volume 有效容積 G r u n d f o s F L O W T H I N K I N G9 ? The start level and stop level must be as close as possible to ? 啟停液位的距離應(yīng)盡可能小,從而 ?shorten the stay time of the wastewater ?縮短廢水停留時(shí)間 ?Reduce the performance variation Q, H and η ?減少 Q, H and η的變化 At least at the top of the motor 最小到電機(jī)的頂部 Effective Volume 有效容積 ?2 Start level 啟泵液位 Stop level 停泵液位 ?2 Effective Volume 有效容積 G r u n d f o s F L O W T H I N K I N G10 ?2 Effective Volume 有效容積 ? The right distance between start and stop is very important: ? 啟停液位之間的距離非常重要 – To short a distance may cause overload of the motor due to many start and stop. – 距離太近,電機(jī)頻繁啟停導(dǎo)致過載。)( PUST) ? 底部傾斜 (45 176。G r u n d f o s F L O W T H I N K I N G1 Key Factors for PS Design 泵站設(shè)計(jì)關(guān)鍵因素 G r u n d f o s F L O W T H I N K I N G2 ?
