Novel high-lift submersible pump

Abstract

The invention discloses a novel high-lift submersible pump, and belongs to the technical field of submersible pumps. The novel high-lift submersible pump comprises a pump body, the lower end of the pump body is provided with a machine shell, a motor is arranged in the machine shell, the bottom of the pump body is provided with a water inlet, a blockage removing assembly is arranged in the water inlet, the blockage removing assembly comprises a fixed seat fixed on the inner wall of the water inlet, a support column penetrating through the fixed seat is arranged in the fixed seat, and a filter screen is arranged at the end, close to the pump body, of the support column. Blocked meshes of the filter screen can be subjected to blockage removal through the blockage removing mechanism, and whenimpurities adsorbed on the filter screen are excessive and water flow cannot normally pass through the filter screen, the filter screen is influenced by the attraction force of the submersible pump and is close to an ejector rod, the ejector rod penetrates through the filter screen through the meshes in the filter screen, so that the effect of dredging the filter screen is achieved, after the filter screen is dredged, the attraction force on the filter screen is reduced, the filter screen is reset under the elastic force of a spring, the filter screen does not need to be disassembled and cleaned, and time and labor are saved.

Description

technical field [0001] The invention belongs to the technical field of submersible pumps, and in particular relates to a novel high-lift submersible pump. Background technique [0002] Submersible pump is a commonly used device, which is widely used in the process of collecting water from rivers, lakes, deep wells and other water sources. When in use, the whole unit dives 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, can also be used for fountain landscape, is the key equipment to provide high-lift, high-pressure liquid. Energy promotion is increasing day by day, and the demand of users for submersible pumps for wells is increasing, and the requirements for pump performance are also increasing day by day. The water inlet of existing submersible pumps is generally equipped with a filter to prevent excessive impurities from blocking the impell...

[0002] Submersible pump is a commonly used device, which is widely used in the process of collecting water from rivers, lakes, deep wells and other water sources. When in use, the whole unit dives 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, can also be used for fountain landscape, is the key equipment to provide high-lift, high-pressure liquid. Energy promotion is increasing day by day, and the demand of users for submersible pumps for wells is increasing, and the requirements for pump performance are also increasing day by day. The water inlet of existing submersible pumps is generally equipped with a filter to prevent excessive impurities from blocking the impeller. , causing damage, but the filter screen should be cleaned frequently, otherwise it will cause blockage of the channel opening and reduce the conveying efficiency, but the filter screen is troublesome to disassemble, and it is inconvenient to clean, and the pump body needs to be taken out, which is time-consuming
