恒压供水系统设计与节能优化——基于单片机控制的高校校园供水系统改进

With the increasing demand for water resources and the importance of water conservation, the design of a constant pressure water supply system based on a single-chip microcomputer has become essential. This design addresses the issues of high energy consumption, low reliability, water waste, and the need for improvement in pipeline systems in campus water supply systems. The proposed system combines the use of tap water constant pressure supply and water pump lifting, along with components such as frequency converters, soft starters, single-chip microcomputers, microleak compensators, pressure sensors, and liquid level sensors to control the water pump speed based on the pressure in the pipeline, ensuring that the pressure remains within the appropriate range. This solution effectively resolves the problems of inadequate pressure due to high-rise buildings and high energy consumption at low flow rates. Furthermore, the energy consumption of the water pump is proportional to the cube of the motor speed, making the energy-saving effect of speed-adjustable operation significant, with energy savings of nearly 40% compared to conventional water supply methods. By incorporating a programmable controller, the system enables variable frequency control of the main pump, soft starter operation of the auxiliary pump, and includes short-circuit protection and overcurrent protection functions, ensuring stable and reliable operation while extending the motor's lifespan. The constant pressure variable frequency water supply system with the single-chip microcomputer provides an efficient and reliable solution for improving the campus water supply system's performance and sustainability, contributing to the conservation and efficient use of water resources. Key words: constant pressure variable frequency water supply, single-chip microcomputer, differential pressure water supply, automatic.
