Embodiment Construction
[0033] Such as figure 1 As shown, the non-contact sensor is used to collect the current signal of the motor line in the booster pump. The non-contact sensor can specifically choose the Hall current sensor, and the live wire of the three-phase electricity passes through the detection hole of the Hall current sensor. The current signal of the pump is used to judge the current water flow of the pump, so as to replace the work of installing a flowmeter on the pipeline to realize non-contact sensing; the pump model module is based on the functional relationship between the current characteristics of the pump motor and the external characteristics of the pump, and the This is used as a model for the booster pump adjustment, and then according to the actual demand working conditions as conditions, the solution module is used to solve it to obtain the adjustment scheme, and then the control module outputs control signals to adjust the working conditions of the pump. The frequency conv...

The invention relates to a sea water desalination booster pump operation control method based on a non-contact sensor, and solves the technical problems of impeller inlet and outlet backflow, cavitation, accompanied noise and vibration and high energy consumption caused by market movement of an existing sea water desalination booster pump under a non-design working condition. A non-contact sensor is used for collecting current signals of a booster pump motor, a pump model module is used for establishing a function relation between current characteristics of the pump motor and external characteristics of a pump, the function relation is used as a booster pump adjusting model, then the function relation is solved by using a solving module according to actual demand working conditions, and an adjusting scheme is obtained. And then a control signal is output through the control module, the working condition of the pump is adjusted, and non-contact sensing optimization adjustment is achieved.
Description
technical field [0001] The invention relates to the technical field of pump energy-saving operation, in particular to an operation control method of a seawater desalination booster pump based on a non-contact sensor. Background technique [0002] Desalination of seawater is an effective way to alleviate and solve the problem of scarcity of freshwater resources. Seawater desalination technology has been developing vigorously for decades. Among them, reverse osmosis seawater desalination technology is widely used in seawater desalination projects due to its mature technology, stability and reliability, and low energy consumption for water production. It has been widely used, and the seawater desalination booster pump is the core power component of the reverse osmosis seawater desalination system, which is used to pressurize the seawater to the required working condition, so that the seawater can reach the reverse osmosis condition. The booster pump is often operated under non-...
