Intelligent water energy circulating electricity-saving system

Abstract

The invention discloses an intelligent water energy circulating electricity-saving system. The problems that a traditional system does not have the electricity generating function, maintenance and operation management are inconvenient, and energy consumption is high are solved. The intelligent water energy circulating electricity-saving system is composed of an intelligent control device, a waterturbine bypass and an efficient water pump bypass, a first temperature sensor, a pressure sensor and a flow sensor are mounted on a water return pipeline, a second temperature sensor is mounted on a water supply pipeline, a third temperature sensor is mounted on a bearing seat of a water turbine, a displacement sensor is mounted on a servomotor of the water turbine, related parameters of the waterreturn pipeline and the water supply pipeline are collected by the sensors and provided for a PLC of an intelligent control cabinet 1, the changes of the real-time temperature, the pressure and the flow, collected by the sensors, of the water return pipeline and the change of the temperature, collected by the sensors, of the water supply pipeline are compared with set values of parameters required by a water supply system by the PLC, when one of the parameters exceed the corresponding set value, the PLC adjusts the flow of the water turbine and the flow of a water pump of the water supply pipeline through a hydraulic station and the servomotor, and thus the corresponding parameter is restored into 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
