水塔液位控制系统是我国住宅小区广泛应用的供水系统,传统的控制方式存在控制精度低,能耗大的缺点。在水资源日益匮乏的今天,节约用水,提高水资源的利用率就显得十分必要。传统的水塔液位控制为粗放式,基本没有对水泵的合理控制,且多为人力控制,工作强度大,危险性高,所以除了浪费电能外,还造成了人员的浪费。采用新型的PLC控制供水方式与过去旧的控制方式相比,在运行的经济性、可靠性及稳定性等方面有显著优势,特别是在提倡低碳的情况下有很好的节能效果,且由于PLC强大的扩展性可以适应今后城市供水建设的发展需要。
Water tower liquid level control system is a widely used residential water supply system in our country. The traditional control methods have the defects of low control accuracy and large energy consumption. In the increasingly scarce water resources today, saving water and improving the utilization rate of water resources become very necessary. The traditional water tower level control for the extensive, basically no reasonable control of the pump, and more manpower control, work intensity, high risk, so in addition to waste of energy, but also caused a waste of staff. Compared with the old control methods used in the past, the new PLC-controlled water supply method has obvious advantages in economy, reliability and stability of operation, and especially in the case of promoting low-carbon energy, and Because of PLC’s strong scalability can adapt to the future development of urban water supply needs.
