Submersible pumps are important equipment for deep well water extraction. When in use, the whole unit dives into the water to work, extracting groundwater to the surface, which is used for domestic water, mine rescue, industrial cooling, farmland irrigation, seawater lifting, ship load regulation, and can also be used for fountain landscapes.
Hot water submersible pumps are used for hot spring bathing, and can also be used to extract groundwater from deep wells, and can also be used in rivers, reservoirs, canals and other water-lifting projects. It is mainly used for farmland irrigation and water for people and animals in high mountain areas. The general flow can reach 5~650m³/h, and the lift can reach 10-550 meters.
Let's take a look at the working principle of the submersible pump:
There are several types of submersible pumps, and the wire wraps in the motor are oil-immersed, water-immersed, and dry.
Before using it, you must read the manual first, you can't make a mistake, if you don't use it for a long time, you must turn the impeller before using it, otherwise it will burn the bag because it will not be stuck for a long time. Before starting the pump, the suction line and the pump must be filled with liquid. After the pump is turned on, the impeller rotates at a high speed, and the liquid in it rotates with the blades. Under the action of centrifugal force, it flies away from the impeller and is ejected outward. The ejected liquid gradually slows down in the diffusion chamber of the pump casing, and the pressure gradually increases. Outlet, the discharge pipe flows out. At this time, a vacuum low-pressure area with neither air nor liquid is formed at the center of the blade due to the liquid being thrown around. The liquid in the liquid pool flows into the pump through the suction pipe under the action of the atmospheric pressure on the pool surface, and the liquid is thus continuous. It is continuously sucked up from the liquid pool and continuously flows out of the discharge pipe.
