Abstract

The invention relates to the technical field of submersible pumps, in particular to a submersible pump not prone to be blocked for a well. The technical problem to be solved by the pump is that filterscreens at the input ends of part of submersible pumps existing in the market are blocked after long-time use. In order to solve the technical problem, the submersible pump not prone to be blocked for the well comprises a submersible pump main body, wherein the surface of the output end of the submersible pump main body is fixedly sleeved with a sliding ring. In the using process of the submersible pump, for the situation that the surfaces of a blocking box and a filtering through opening set are contaminated with soil to be blocked in the using process of the submersible pump main body, at the moment, linear motors are started to enable the two linear motors to reciprocate in the same direction in a direction of a primary limiting block and a secondary limiting block through two arc-shaped guide rods correspondingly, at the moment, a rotary-connection ring rotates with the sliding ring as the base point through an annular sliding groove, and at the moment, the blocking box rotates ata high speed to generate centrifugal force to enable the soil on the surface of equipment to fly around to complete clearing.

Description

technical field [0001] The invention relates to the technical field of submersible pumps, in particular to a submersible pump for wells which is not easily blocked. Background technique [0002] The submersible pump is a special pump used for lifting water resources in high-depth environments, and submersible pumps are divided into well submersible pumps, working face submersible pumps, submersible sewage pumps, sand discharge submersible pumps and Different types of mining vertical pumps, etc., in the process of using submersible pumps for wells, in order to prevent impurities in the water from entering the submersible pump with the water flow, filter screens are used to filter them. After a period of use, it will be blocked and affect the normal use of the submersible pump. Contents of the invention [0003] (1) Solved technical problems [0004] Aiming at the deficiencies of the prior art, the present invention provides a well submersible pump that is not easy to be b...
