管中泵的扬程(head of the pump)为什么变低？

管中泵的扬程(head of the pump)为什么变低？
井管内流量下降和泵头下降与管中泵流量过大、沉没深度不足、叶轮或泵体流道被碎屑堵塞有关。
（1） 泵叶轮或泵体流道被杂物堵塞，泵叶轮或泵体流道堵塞，会降低管中泵在井管内的流量和扬程。处理方法是拆开水泵，清除叶轮或泵体流道内的杂物，使叶轮平稳快速转动，泵体流道畅通，重新检修水泵。
（2） 管中泵反转的处理方法是更换任意两相的电源线或电机接线。
（3） 处理方法是加长出水管，增加电机和泵的沉没深度。
（4） 井涌水量小，井涌水量小，跟不上管中泵的出水量。因此，井内动态水位不断下降，泵在管内的扬程不断增大，流量逐渐减小。处理方法是适当调整阀门，减小小管道内泵的流量，使其适应井涌水量，在小流量管内更换泵，或重新修井。再过十年，十年风雨，十年锤炼，十年风雨，十年战略，市场瞬息万变，风云变幻。龙亚已发展成为QQH的业务战略布局，并执着于共同的梦想！以上就是管中泵扬程变低,泵的扬程为什么变低的全部答案。欢迎您进一步了解管中泵的更多使用问题解决方案，请留意上海龙亚管中泵官方网站。

Why is the head of the pump in the pipe low?
The decline of flow rate and pump head in well pipe is related to the excessive flow rate of pump in the pipe, insufficient submergence depth and blockage of impeller or pump body flow passage by debris.
(1) Pump impeller or pump body flow channel is blocked by debris, pump impeller or pump body flow channel is blocked, which will reduce the pump flow and head in the well pipe. The treatment method is to dismantle the water pump, remove the debris in the impeller or pump body flow channel, make the impeller rotate stably and rapidly, and the pump body flow channel is smooth, and overhaul the water pump again.
(2) The treatment of pump reversal is to replace any two-phase power line or motor wiring.
(3) The treatment method is to lengthen the outlet pipe and increase the submergence depth of motor and pump.
(4) The well water inflow is small, which can not keep up with the water output of the pump in the pipe. Therefore, the dynamic water level in the well continues to drop, the head of the pump in the pipe continues to increase, and the flow rate gradually decreases. The treatment method is to adjust the valve properly, reduce the flow of the pump in the pipeline, make it adapt to the well water inflow, replace the pump in the small flow pipe, or repair the well again.
