"고려해야 합니다,因为在介质密度不同,选用的电机功率不同,不然电机可能出现电流现象。汽柴油泵在线水联运时电流往往就出现。"

"물론 밀도를 고려해야 합니다.一方面要选择合适的电机功率,另一方面要计算泵出口压力的大小,介质密度大的同样的扬程泵出口压力大,反之小。"

"고려해야 합니다. 주로과功率有关,粘度也是一样,同样的参数,密度和粘度不同,功率也不同,对电机影响很大。"

"펌프 선택은 주로介质粘度,配备的电机要考虑密度"
Reply #92019-06-19
"고려해야 합니다. 펌프 선택과 설치 높이,排出高度,效率,液体密度,液体粘度,液体饱和蒸汽压,管径,直管长度,截止阀数目,底阀数目,管件数,液体绝对粗糙度,管件阻力系数都有关。"
