The moment when a sudden stop pump, pump the water lateral pressure drastically reduced, while the suction side pressure is substantially increased under the action of this pressure, circulating water pump suction side piping of water that is open the valve to the pump outlet side of the pipeline system, thereby reducing the suction side increased the pressure pipe network in the magnitude; to reduce and prevent water hammer damage.
当突然停泵的瞬间，泵出水侧压力急剧降低，而吸水侧压力则大幅度增高，在此压差作用下，循环水泵吸水侧管路中的水即推开止回阀至泵出水侧的管网系统，从而降低了吸水侧管网中压力增高的幅度；减少和防止了水锤的危害。
Test shows that the self-priming height and period of the pump vary with the viscocity of the fluid delivered and the self-priming performance is also affected by the gas content in fluid, installing height of pump and immersed depth of suction pipe.

Submersible pump and water pump common difference is it works under water, and pumps most of the work on the ground. The working principle of submersible pumps: submersible pump pump before opening, suction pipes and pumps must be filled with liquid. Open pump, the impeller rotating speed, diving pump with the liquid with the rotating blades, in the role of centrifugal force, the left outside impeller injection, injection of the liquid in the pump shell gradually slow the spread of indoor speed, the pressure gradually increased, and then from the pump outlet, the outflow discharge tube. At this point, in the leaf center left as a result of the liquid formed by the surrounding air do not have a vacuum there is no area of low pressure liquid, liquid-pool surface of the liquid in the role of atmospheric pressure, the pipe flows through inhalation submersible pump, the liquid is continuously pumped from the liquid pool was up and continuous outflow from the discharge pipe. Submersible pump of the basic parameters: including the flow, head, pump speed, supporting power, rated current, efficiency, diameter and so on.
鱼缸潜水泵一种用途非常广泛的水处理工具潜水泵与普通的抽水机不同的是它工作在水下，而抽水机大多工作在地面上开泵后，叶轮高速旋转，潜水泵中的液体随着叶片一起旋转，在离心力的作用下，飞离叶轮向外射出，射出的液体在泵壳扩散室内速度逐渐变慢，压力逐渐增加，然后从泵出口，排出管流出此时，在叶片中心处由于液体被甩向周围而形成既没有空气又没有液体的真空低压区，液池中的液体在池面大气压的作用下，经吸入管流渗入渗出潜水泵内，液体就是这样连续不断地从液池中被抽吸上来又连续不断地从排出管流出潜水泵的基本参数：包括流量、扬程、泵转速、配套功率、额定电流、效率、管径等等。
