The phase difference of mass unbalance and bend of rotor will affect the size of coupling zone and the coupling vibration in two coupling zones.
质量偏心与转子弯曲的相位差会影响耦合区的大小及耦合区内的耦合振动；
To horizontal bend, the displacement of axial and horizontal direction is larger than vertical direction. The displacement of pipe is mainly caused by the impact of two-phase flow.
对于水平弯管，轴向和水平方向上的变形要比垂直方向上的大，管道变形主要是由流体对管道的冲击作用引起；
Scoring Part: adopt 5 points scoring, scoring distance in-phase adjust, blazonry and easy to bend the carton sheet.
压痕部：采用五点压线，压痕间隙同步调整线型美观，不爆线，易于折弯。
