单片机在泵站液压控制蝶阀上的应用

Application of monolithic integrated circuit in hydraulic control reed valve of pumping station

为了防止高扬程输水泵站中水锤的产生,采用8031芯片利用PID控制器、高精度智能传感器及其外围设备设计出一种智能型的泵站液控蝶阀系统.该设计可使电机转速与管道压力达到动态平衡,既防止了水锤的产生,又保护了设备的安全.在试运行中,该系统比较好地解决了水锤问题,设备的可靠性有了大幅度地提高,且人工调试简单,能适应各种扬程的输水泵站,可与泵站的自动控制系统相互兼容;但设备各部件投资较大,对部件的可靠性及抗电磁干扰性要求比较高,需要在今后进一步完善.

To prevent the phenomena of water hammer in high-lift pumping water station, one kind of intelligent butterfly valve control system of pump station is designed with 8031CPU, PID controller, high accuracy intelligent sensor and other peripheral equipment. This design not only rotate speed of electromotor and pipeline pressure can be homeostasis, but also prevents the phenomena of water hammer and makes equipment safety. For the solution of water hammer reliability of equipment is enhanced during the testing time. At the same time, manual debugging is simple and can be used in every lift pumping water station and is compatible to control system of pumping station. It is to be improved at the further time, such as more expensive and high reliability and anti-electromagnetic-jamming of parts.
