The general flow can reach 5-650 m ³ And the lift can reach 10-550 m.

Before the pump is started, the suction tube and the pump must be filled with liquid. After the pump is started, the impeller rotates at a high speed, liquid in the impeller rotates along with the blades, flies away from the impeller to be ejected outwards under the action of centrifugal force, the ejected liquid gradually slows down in the diffusion chamber of the pump shell, the pressure gradually increases, and then the ejected liquid flows out of the pump outlet and the discharge pipe. At this time, a vacuum low-pressure area without air and liquid is formed at the center of the vane because the liquid is thrown to the periphery, the liquid in the liquid pool flows into the pump through the suction pipe under the action of the atmospheric pressure of the pool surface, and the liquid is sucked from the liquid pool continuously and flows out of the discharge pipe continuously. This is the principle of operation of the submersible pump.

When the pulling button is arranged on the left side, the distance between the water inlet of the pump and the ground is small, so that the low-height water absorption function of the pump can be realized, but the water yield is relatively small; when the pulling button is pulled to the right side, the supporting leg heightens the pump, the distance between the water inlet of the pump and the ground is increased, the pump can realize high-flow water pumping, and the residual water level after the water pumping is relatively more.

The utility model has the technical effects and advantages that:

1. the pump has the advantages that the structure is simple and reliable, the function can be realized by adding one part on the basis of no pump with the function, and other structures of the pump can not be influenced.

2. The structure is convenient to install, and can be installed by only fixing the adjusting supporting legs on the base.

3. The use is more convenient, and the adjustment of the height of the water inlet of the pump can be realized only by stirring the stirring button, thereby selecting the low-height water absorption function or the high-flow water absorption function. When the water absorption is low or the water is relatively clear, the dial knob can be stirred to reduce the height of the water inlet (namely, the distance between the water inlet and the mounting surface is smaller), and the mounting surface can be wiped and vacuumized for drying when the height of the water inlet is lower, namely, the mounting surface can be vacuumized to the extent that only one thin layer of liquid is left. When the water level is required to be high or the water is turbid, the poking button can be poked to raise the height of the water inlet (namely, the distance between the water inlet and the mounting surface is larger), and the advantage of the poking button is that the flow resistance of the sucked liquid can be very low, so that the submersible pump has high conveying capacity; furthermore, due to the increased distance between the water inlet and the mounting surface, even severely contaminated liquid can be pumped out reliably, since larger dirt particles can reach the water inlet.

4. The structure is arranged in the pump base, the overall appearance aesthetic property of the pump is not affected, the space of the pump base is reasonably utilized, and the influence of the structure on the volume of the pump base is relatively reduced.

5. The parts are simple in structure (mainly refer to the adjusting piece), the production cost is low, and then the production cost of the whole submersible pump is relatively low.
