Submersible pump is an important equipment for extracting water from deep wells. When used, the whole unit dive into the water to work, the groundwater is extracted to the surface, is the water for life, mine rescue, industrial cooling, farmland irrigation, sea water upgrade, ship transfer, can also be used for fountain landscape.
Submersible pump must first look at the instructions, can not be mistaken, long-term need not, must be used before the impeller to turn, otherwise it will be buns because of the long-term need not die. Before opening the pump, the suction tube and the pump must be filled with liquid. Open the pump, impeller high-speed rotation, where the liquid with the blade rotation, under the action of centrifugal force, flying away from the impeller outward, the injection of liquid in the pump shell diffusion indoor speed gradually become slower, pressure gradually increased, and then from the pump outlet, discharge pipe outflow. At this point, at the center of the blade, the liquid is flung around to form a vacuum low-pressure zone with neither air nor liquid, the liquid in the liquid pool in the pool surface atmospheric pressure, the suction tube into the pump, the liquid is so continuously from the liquid pool is sucked up and continuously from the discharge pipe outflow.
