电源模块 24VDC/68W NT255
液力耦合器是一种液力传动装置,一般由泵轮和涡轮组成,它们统称工作轮,放在密封壳体中。壳中充入一定量的工作液体,当泵轮在原动机带动下旋转时,处于其中的液体受叶片推动而旋转,在离心力作用下沿着泵轮外环进入涡轮时,就在同一转向上给涡轮叶片以推力,使其带动生产机械运转。液力耦合器的动力转输能力与壳内相对充液量的大小是一致的。在工作过程中,改变充液率就可以改变耦合器的涡轮转速,做到无级调速。本方法适用于风机、水泵的调速。
其特点为:1、功率适应范围大,可满足从几十千瓦至数千千瓦不同功率的需要;2、结构简单,工作可靠,使用及维修方便,且造价低;3、尺寸小,能容大;4、控制调节方便,容易实现自动控制。
