There exists a saddletype zone in the hydraulic moment curve of axial-flow pump blades which corresponds to the saddle zone of discharge-head characteristic curve of the pump.
轴流泵叶片水力矩随流量变化的关系曲线存在一个马鞍区，并与流量-扬程曲线的马鞍区相对应。

An advantage of this type of saddle clamp was that permanent repair could be made by welding the steel piece to the pipe and then removing the bolted portions.
这类鞍形管卡的优点是可对管道泄漏点进行永久性修理，把钢板和管子焊接，然后拆走螺栓部分。
