Intelligent water energy cycle power saving system

Abstract

The invention is an intelligent water energy cycle power-saving system, which solves the problems that the traditional system has no power generation function, inconvenient maintenance and operation management, and high energy consumption. It consists of an intelligent control device, a turbine bypass, and a high-efficiency water pump bypass. The first temperature sensor, pressure sensor and flow sensor are installed on the return water pipeline, the second temperature sensor is installed on the water supply pipeline, and the third sensor is installed on the bearing seat of the turbine. The temperature sensor is installed on the servomotor of the water turbine. The displacement sensor is installed. The sensor collects the relevant parameters of the return water and the water supply pipeline and provides them to the PLC programmable controller of the intelligent control cabinet 1. The programmable controller collects the real-time data of the return water pipeline according to the sensor Changes in temperature, pressure, flow and temperature of the water supply pipeline are compared with the set values ​​of the parameters required by the water supply system. When one of these parameters exceeds the set value, the programmable controller adjusts the water turbine through the hydraulic station and the servomotor The flow rate and the flow rate of the water pump in the water supply pipeline make this parameter return to the set value range.

Description

technical field [0001] The invention is related to the energy saving of the pump water supply system. Background technique [0002] Many pump water supply systems currently use one or several water pumps to pressurize the water and deliver it to the required scene. There are many ways to deal with the used water flow. Some lead the water to the water treatment equipment and then discharge it to the river; some discharge it underground; recycle. However, the water flow after use often also has a large amount of water energy: first, there is still surplus potential energy. For example, the ground source heat pump takes water from the ground to the ground and then flows into the potential energy of the ground. The equipment or materials in the factory need to be cooled by the heat exchanger. Because the process requires a higher installation position, the cooling water flows from the high-level heat exchanger to the hot water pool or into the cooling tower, and there is stil...

Problems solved by technology

Third, in order to ensure that the water supply flow meets the maximum needs of users, the designer must design the water supply pump according to the maximum required flow, and consider the safety factor. Therefore, the actual flow of the pump has a large margin

Fourth, due to changes in ambient temperature and user needs, there is a surplus in actual traffic

The shaft extension tubular turbine converts the residual pressure of the system into kinetic energy and directly provides it to the high-efficiency water pump, replacing or reducing the power consumption of the motor, thereby reducing the energy consumption of circulating water. This technology is only applicable to those with low return water pressure and small return water energy. Circulating water system, its use range is not wide, and the power saving effect is not ideal

And it is troublesome to use the operation management
