Abstract

The invention provides an electric pump control method and system. The electric pump control method comprises the following steps that a current rotating speed, a current and a current voltage of theelectric pump are collected; whether the electric pump is in a normal operation mode or not is judged according to the current and the current voltage; if a current rotating speed is in a normal operation mode, whether the current rotating speed is in a calibrated rotating speed range or not is judged; and if the rotating speed is not within the range of the calibrated rotating speed, the currentrotating speed is corrected, and a correcting result is recorded. According to the the electric pump control method and system, the problem that an electric pump control method in the prior art is lowin efficiency can be solved, and the electric pump can be effectively controlled.

Description

technical field [0001] The invention relates to the technical field of electric pumps, in particular to an electric pump control method and system. Background technique [0002] A pump is a machine that transports fluid or pressurizes the fluid. During use, the pump can transfer mechanical energy or other external energy to the liquid to increase the energy of the liquid, and then achieve the purpose of transporting the liquid to a high place. Generally, pumps can be divided into electric pumps and water turbine pumps according to the driving method. Electric pumps are pumps driven by electricity. When in use, electric energy is converted into raw energy for increasing liquid energy. More convenient, therefore, the application of electric pump is more and more extensive. [0003] In the prior art, the research on the control method of the electric pump is relatively blank, and the control efficiency is low, which affects the stable operation of the electric pump.
