2、新疆一体化污水处理设备高扬程水泵用于低扬程抽水

一些管道离心泵用户认为抽水扬程越低,电机负荷越小。在这种错误认识的误导下,选购生活污水一体化设备中水泵时,常将水泵的扬程选得很高。新疆一体化污水处理设备其实对于离心式水泵而言,当水泵型号确定后,其消耗功率的大小是与水泵的实际流量成正比的。而水泵的流量会随扬程的增加而减小,因而扬程越高,流量越小,消耗功率也就越小。反之,扬程越低,流量越大,消耗的功率也就越大。因此,为了防止电机过载,一般要求水泵的实际抽水使用扬程不得低于标定扬程的6O%。所以当高扬程用于过低扬程抽水时,电机容易过载而发热,严重时可烧毁电机。若应急使用,则必须在出水管上装一个用于调节出水量的闸阀(或用木头等物堵小出水口),以减小流量,防止电机过载。注意电机温升,若发现电机过热,应及时关小出水口流量或关机。这一点也容易产生误解,有些机手认为堵塞出水口,强制减少流量,会增加电机负荷。其实正好相反,正规的大功率离心泵排灌机组的出水管上都装有闸阀,为了减小机组启动时的电机负荷,应先关闭闸阀,待电机启动后再逐渐开启闸阀就是这个道理。

3、GUANDAOLIXINBENGJINSHUIGUANLUSHANGWANTOUDUO

如果新疆一体化污水处理设备在进水管路上用的弯头多,会增加局部水流阻力。并且弯头应在垂直方向转弯,不允许在水平方向转弯,以免聚集空气。

这样做会使新疆一体化污水处理设备的进水管内聚集空气,降低水管和水泵的真空度,使水泵吸水扬程降低,出水量减少。正确的做法是:其水平段应向水源方向稍有倾斜,不应水平,更不得向上翘起。

5、设底阀时,进水管最下一节不是垂直的

6、管道离心泵进水口与弯头直接相连

8、管道离心泵出水管口在出水池正常水位以上

如果新疆一体化污水处理设备的出水口在出水池正常水位以上,虽增加了水泵扬程,但减少了流量。如因地形条件所限,出水口必须高出出水池水位,则应在管口加装弯头和短管,使水管成为虹吸式,降低出水口高度。
