离心泵的八大使用误区

2019-11-13

     离心泵作为工业和农业生产中比较常用的元件,在使用过程中,不了解的人会存在比较大的误区,下面例举使用中的八大误区。 

     一、管道与离心泵不匹配

     一些使用者错误的认为,把管径缩小,可以提高实际的扬程,实际上离心水泵的实际上水泵扬程=总水泵扬程-损害水泵扬程。当水泵型号明确后,总水泵扬程是一定的;损害水泵扬程关键来源于于管道摩擦阻力,管经越小显而易见摩擦阻力越大,因此损害水泵扬程越大,因此减少管经后,离心水泵的实际上水泵扬程不但不可以提升,反倒会减少,造成离心水泵高效率降低。同样,当小管经离心水泵用大自来水管输送水时,也不容易减少离心水泵的实际上水泵扬程,反倒会因为管道的摩擦阻力减少而减少了损害水泵扬程,使实际上水泵扬程逐步提高。也有机化学手觉得小管经离心水泵用大自来水管输送水时,必定会大大增加电动机负载,她们觉得管经扩大后,出水口里的水对水泵的工作压力就大,因此会大大增加电动机负载。却不知道,液体压强的尺寸只与水泵扬程高矮相关,而与自来水管截面尺寸不相干。要是水泵扬程一定,离心水泵的离心叶轮规格不会改变,不管管经多少,功效在离心叶轮上的工作压力全是一定的。仅仅管经扩大后,流水摩擦阻力会减少,进而总流量有所增加,驱动力耗费也是适度提升。但要是在额定值水泵扬程范围之内,不管管经怎样提升离心水泵全是能够一切正常工作中的,而且可以减少管道耗损,提升离心水泵高效率。

      二、搞扬程水泵用于低扬程

      三、离心泵进水管路上弯头多

      四、进水管路,水平段水平或者上翘

     五、离心泵进水口与弯头直接连接

     六、离心泵出水管口在出水池正常水位以上

     七、进水管的进水口位置不对

       八、设底阀时,进水管最下节不是垂直的

      如这样安装,阀门不能自行关闭,造成漏水。正确安装方法是:装有底阀的进水管,最下一节尽量是垂直的。如因地形条件限制不能垂直安装,则水管轴线与水平面夹角应在60°以上。


       管道离心泵是各领域使用最多,最为广泛的泵型,制药广大用户了解了管道离心泵的八大误区,尽量避免以上所述。上海阳光泵业是专业的管道离心泵的生产厂家具有丰富的生产经验和完善的检测设备,从而保证产品质量的稳定、可靠、使用寿命长等优势。
