higher怎么理解(关于离心泵排出扬程)? XXX pumps should never be allowed to run dry to determine the direction of rotation of the pump. To determine the correct direction of rotation, a pressure gauge should be installed on the discharge side of the pump. Generally, discharge head would be 40 to 50% higher with the correct direction of rotation. 原译:不得为确定泵旋转方向而让 XXX 泵干运行,一个 压力表 应安装在泵的排出侧。通常,在正确的旋转方向下, 排出扬程应为 40% ~ 50% 以上。(欢迎大家各抒已见) 查看更多13个回答 . 1人已关注
