Abstract

The invention discloses a smart sensing type submersible electric pump. A water inlet optical fiber sensor (1) and a water outlet optical fiber sensor (4) which are used for measuring the lift of the submersible electric pump are arranged on the submersible electric pump; the water inlet optical fiber sensor (1) is arranged at the water inlet of the submersible electric pump and used for sensing the water pressure of the water inlet; the water outlet optical fiber sensor (4) is arranged at the water outlet of the submersible electric pump and used for sensing the water pressure of the water outlet; an optical fiber liquid level sensor (6) for sensing the position and submerged depth of the submersible electric pump is arranged at the upper part of the submersible electric pump. According to the submersible electric pump, test and reading of the lift and submerged depth can be performed on site anytime, no special test system needs to be arranged and the submersible electric pump has a positive significance for assessment of the comprehensive performance and safe operation status of a submersible electric pump.

Description

technical field [0001] The invention belongs to the technical field of environmental protection, in particular to an intelligent sensing type submersible electric pump. Background technique [0002] Submersible electric pumps are widely used in a series of water supply and drainage projects such as urban water supply, sewage treatment, urban construction, industrial and mining docks, farmland irrigation, and power stations. Liquids whose physical and chemical properties are water can be transported. The motor of the submersible electric pump drives the impeller to rotate through the transmission shaft, and does work on the liquid to increase its energy, so that the required amount of liquid is transported from the suction pool to the required high place or a place requiring a certain pressure through the flow-passing parts of the pump. Submersible electric pumps are divided into three types: centrifugal pumps, mixed-flow pumps and axial-flow pumps according to the form of i...
