Submersible pump

Abstract

The invention relates to a submersible pump. The submersible pump comprises a supporting base, a pump body, a water inlet pipe, a water filtering sleeve and a water outlet pipe. The pump body is installed on the supporting base, the water inlet pipe is installed at the lower end of the pump body, the water inlet pipe and the water filtering sleeve are connected together, the water filtering sleeve is installed on the supporting base, and the water outlet pipe is installed at the upper end of the pump body. The submersible pump can solve the following problems when an existing submersible pump is used, a, silt at the bottom of a river is frequently pumped out when the existing submersible pump is used for pumping water, so that the pumped and blown water flow needs to be filtered by workers by consuming a lot of working hours, and the workload of the workers is greatly increased; and b, in the water conveying process of an existing water pump, a water conveying pipe and the water outlet end of the pump body need to be connected together manually, then in the water conveying process, the position of the water conveying pipe needs to be adjusted due to the change of the water needing position, and after long-time adjustment, the contact position of the water conveying pipe and the pump body can be broken, and the water conveying efficiency is influenced.

Description

technical field [0001] The invention relates to the technical field of submersible pumps, in particular to a submersible pump. Background technique [0002] Submersible pump is an important equipment for deep well water extraction. When in use, the whole unit submerges into the water to extract groundwater to the surface. It is used for domestic water, mine emergency, industrial cooling, farmland irrigation, seawater lifting, ship load adjustment, and can also be used for fountain landscape. Existing submersible pumps are not used for a long time, and the impeller must be rotated before use, otherwise the package will be burned due to long-term non-use. Before the submersible pump is turned on, the suction pipe and the pump must be filled with liquid. After the pump is turned on, The impeller rotates at high speed, and the liquid in it rotates with the blades. Under the action of centrifugal force, it flies away from the impeller and shoots out.

[0002] Submersible pump is an important equipment for deep well water extraction. When in use, the whole unit submerges into the water to extract groundwater to the surface. It is used for domestic water, mine emergency, industrial cooling, farmland irrigation, seawater lifting, ship load adjustment, and can also be used for fountain landscape. Existing submersible pumps are not used for a long time, and the impeller must be rotated before use, otherwise the package will be burned due to long-term non-use. Before the submersible pump is turned on, the suction pipe and the pump must be filled with liquid. After the pump is turned on, The impeller rotates at high speed, and the liquid in it rotates with the blades. Under the action of centrifugal force, it flies away from the impeller and shoots out. The speed of the injected liquid gradually slows down in the diffusion chamber of the pump casing, and the pressure gradually increases. Then it flows from the pump outlet to the discharge pipe. Outflow, at this time, because the liquid is thrown to the surroundings at the center of the blade, a vacuum low-pressure area without air and liquid is formed. 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 In this way, it is continuously sucked up from the liquid pool and continuously flows out from the discharge pipe. The submersible pump is widely used in various industries, but the existing submersible pump still has certain deficiencies when it is used.

[0003] The existing submersible pumps often have the following problems when they are used: a: The existing submersible pumps often pump out the sediment at the bottom of the river when pumping water, and then require employees to spend a lot of man-hours to filter the blown water. Greatly increased the workload of employees; b: During the water delivery process of existing submersible pumps, it is necessary to manually connect the water delivery pipe to the water outlet on the pump body. The change of the water delivery pipe needs to be adjusted. After a long period of adjustment, the contact position between the water delivery pipe and the pump body will often be broken, which will affect the water delivery efficiency.
