摘要
许多中小城市长期以来在市政供水、高层建筑供水、工业生产循环供水等方面技术一直比较落后,工业自动化程度低。传统调节供水压力的方式,多采用频繁启/停电机控制和水塔二次供水调节的方式,前者产生大量能耗的,而且对电网中其他负荷造成影响,设备不断启停会影响设备寿命;并且需要大量的占地与投资。随着城市规模和现代化的发展,智能和节能技术的应用与普及已成为一个重要标准,从普遍性和广泛性来说,恒压供水节能控制的应用和普及就值得大力推广,既能保证人们的生活质量不断提高又减少企业的运营成本。因此,通过PLC技术和变频控制的改造就能达到恒压供水,在原有设备基础上完成节省能源、节省人力、确保安全运行,实现少投入,多产出。
Many small and medium-sized cities have long been lagging behind municipal water supply,high-rise building water supply,industrial production cycle water supply and so on,and the degree of industrial automation is low. The traditional way to adjust the water supply pressure,the use of frequent start/stop control and water tower secondary water supply adjustment,the former produce a lot of energy consumption,but also on the other load on the power grid,the equipment will start to stop the equipment life; Need a lot of land and investment. With the development of urban scale and modernization,the application and popularization of intelligent and energy-saving technologies have become an important criterion. From the universality and extensiveness,the application and popularization of energy-saving control of constant pressure water supply should be popularized,The quality of life continues to improve and reduce the operating costs of enterprises. Therefore,through the PLC technology and frequency control of the transformation will be able to achieve constant pressure water supply,based on the original equipment to complete energy conservation,saving manpower,to ensure safe operation,to achieve less investment,more output.
