渣浆泵可动叶片调节流量扬程

当改变叶片安放角时，泵的性能将随之改变，所以将叶片制作成可转动可改变叶片安装角就可改变泵的性能，从而达到调节的目的。这种方法只能用于轴流泵和混流泵中，尤其是轴流泵中用的较多。改变叶片安放角的方法，常有两种情况，一是固定的调节， 二是运行中可随时调节。固定调节是根据需要的性能确定其叶片安装角，用螺钉拧紧固定，另一种是通过机械方法或液压方法，泵在运行中，随时都可以转动叶片改变叶片安放角进行调节，但其结构复杂，所以常只用于大型泵中。
六、减少叶轮数目调节
    在多级泵中，减少叶轮数目来降低泵的扬程，从而达到调节的目的，所以只能用在多级泵中，调节时，取下1个或2个叶轮和相应的导叶，用一个长度相当的轴套来代替所取下叶轮位置。用这种方法调节时，流量不变，只改变了扬程，减少 一个叶轮就减少一级扬程，这种方法会增加一定的阻力损失，所以取下的叶轮不宜太多，并且应取下最后面的叶轮，否则会造成泵的汽蚀。渣浆泵厂家

Adjustable blade flow head of slurry pump

When the blade angle is changed, the performance of the pump will be changed accordingly, so the performance of the pump can be changed by making the blade into a rotatable and changeable blade angle, so as to achieve the purpose of adjustment. This method can only be used in axial flow pump and mixed flow pump, especially in axial flow pump. There are two ways to change the setting angle of blade, one is fixed adjustment, the other is adjustable at any time during operation. Fixed adjustment is to determine the installation angle of the blade according to the required performance, and tighten it with screws. The other is to adjust the installation angle of the blade by turning the blade at any time during the operation of the pump through mechanical or hydraulic methods, but its structure is complex, so it is often only used in large pumps.

Vi. reduction of impeller number adjustment

In multistage pump, reduce the number of impellers to reduce the pump head, so as to achieve the purpose of adjustment, so it can only be used in multistage pump. When adjusting, remove one or two impellers and corresponding guide vanes, and replace the position of the removed impeller with a shaft sleeve of the same length. When this method is used for adjustment, the flow will not change, only the head will be changed, and the first stage head will be reduced if one impeller is reduced. This method will increase certain resistance loss, so it is not suitable to remove too many impellers, and the last impeller should be removed, otherwise it will cause cavitation of the pump.
