AI Technical Summary

Technical Problem

Traditional water pumps adopt a fixed frequency operation mode and cannot be adjusted according to changes in actual working conditions, resulting in waste of energy consumption and low operating efficiency. Especially when load fluctuations are large or flow demands are frequently changed, they fail to give full play to the advantages of frequency conversion technology.

Method used

The automatic adjustment intelligent frequency conversion water pump control method is adopted to adjust the operating gear level of the water pump according to the outlet pressure and operating mode by preset gear level and calibration power and speed to ensure that the water pump operates at the optimal working point.

Benefits of technology

It realizes the reduction of energy consumption and optimization of operating efficiency of water pumps, quickly responds to outlet pressure and flow demands, adapts to different working environments, extends equipment life and reduces maintenance costs.

Abstract

The invention relates to the technical field of variable-frequency water pump control, and provides an automatic-adjustment intelligent variable-frequency water pump control method and system and terminal device.The intelligent variable-frequency water pump control method comprises the steps that in the presetting stage, a preset number of gear grades are set, and one of the gear grades is selected as the operation gear grade of a variable-frequency water pump; the calibrated power and the calibrated rotating speed of the motor corresponding to the highest energy efficiency point of each gear grade of the variable frequency water pump under different outlet pressures are obtained; in the application stage, an operation mode is selected; and according to the calibrated power corresponding to the outlet pressure and the operation gear grade, the calibrated rotating speed corresponding to the outlet pressure and the operation gear grade and the operation mode, the operation gear grade of the variable-frequency water pump is adjusted, and the variable-frequency water pump operates according to the adjusted operation gear grade. The problems that a traditional water pump can only work at a fixed speed, and the energy efficiency is not high are solved.
