Subject: NPSHRm, NPSHRw Народ кто нибудь встречал, что это за индексы m, w ?NPSHRm, NPSHRw ? Есть также Hr = Hm/Hw - head derating factor Заранее спасибо |
чё-то, смотрю, сложный вопрос оказался... И я не знаю. В порядке практически случайных версий. maximum/working? mud/water? |
The performance of a centrifugal pump on slurries will differ from the performance on water which is the basis for most published curves. Head (H) and rate of flow (Q) will normally decrease as solids size and concentration increases. Power (P) will increase and net positive suction head required will also increase in most circumstances. Starting torgue will also be affected. This is so called "solids effect". m - slurry (ANIS/HI 12.1-12.7 2001) |
