实现变频恒压供水的方法。详细介绍了系统的硬件结构、工作原理和软件实现，并给出了有关控制软件的流程图和PLC功能图。关键词：PLC；变频调速；恒压供水系统；压力日常的生活用水量随季节、昼夜、上下班的时间不同而有较大变化，因而经常出现供水用水的不平衡，主要表现在水压上，用水多而供水少则水压低，用水少而供水多则水压高。某公司住宅区由于自来水管网的水压较低，自来水通常不能到达住宅的较高楼层。要用水泵再次将水送至楼顶的高位水箱，再供应给用户。但是，这种二次供水方式不可避免造成污染，影响居民的身体健康。为保证小区的供水正常，我们利用PLC，配以不同功能的传感器，根据网管的压力，通过变频器控制水泵的转速，使水管中的压力始终保持在合适的范围。这种变频恒压供水系统直接取代水塔、高位水箱及传统的气压罐供水装置。另外水泵耗电功率与

转速的三次方成正比关系，所以水泵调速运行的节能效果非常明显，平均耗电量较通常供水方式节省40％。结合使用可编程控制器，可实现循环变频，电机软启动，具有短路保护、过流保护功能，工作稳定可靠，大大延长了设备的使用寿命。 1　系统设计 (1)原理　　系统采用3台水泵并联运行方式，压力传感器将主水管网水压变换为电信号，经模拟量输入模块，输入PLC，PLC根据给定的压力设定值与实际检测值进行PID运算，输出控制信号经模拟量输出模块至变频器，调节水泵电机的供电电压和频率。当用水量较小时，一台泵在变频器的控制下稳定运行，当用水量大到水泵全速运行也不能保证管网的压力稳定时，PLC给定的压力下限信号与变频器的高速信号同时被PLC检测到，PLC自动将原工作在变频状态下的泵投入到工频运行，以保持压力的连续性，同时将下一台备用泵用变频器起动后投入运行，以加大管网的供水量保证压力稳定。若2台泵运转仍不能满足压力的要求，则依次将变频工作状态下的泵投入到工频运行，再将一台备用泵投入变频运行。当用水量减少时，首先表现为变频器已工作在低速信号有效，这时压力上限信号如仍出现，PLC首先将先工频运行的泵停掉，以减少供水量。当上述2个信号仍存在时，PLC再停掉第2台工频运行的电机，直到后一台泵用变频器恒压供水。　　所有水泵电机从停止到启动及从启动到停止都由变频器来控制，实现带载软启动，避免了启动大电流给水泵电机带来冲击，相对延长了电机的使用寿命。同时，breaking command to control the action of guide groove bottom plate and outlet baffle.

6 problems in use

In practice, abnormal phenomena have occurred in tail cutting, that is, the shear length of the tail is out of control, or even the tail of the rolled piece can not be cut. Through analysis, it is found that the distance from the hot metal detector HMD to the flying shear is too small, which is basically close to the shear advance of the flying shear. In this way, even if the set tail cutting length is very long, the tail may not be cut or cut very short. At first, we solved the problem by improving the speed benchmark of the flying shear motor, but in this way, although we can cut the tail, it leads to another problem: because the shear speed is not synchronized with the rolled piece speed, the shear speed is ahead during head cutting, resulting in additional shear load. During tail cutting, the tail is often bent, causing potential harm to the equipment. After modifying the program, the thermal inspection for starting the tracking of the rolled piece tail is changed from hmd0 before the flying shear to hmdl in front of the previous frame, and the travel of the rolled piece from hmd0 to the frame section is converted to the distance traveled by the rolled piece when traveling at the speed of the rolled piece before cv50 (that is, the ratio of the outlet speeds of the first two frames of cv50 multiplied by the distance from hmd0 to the frame), and it is added to the distance L. After modification, the tailing control is normal.Clutch brake flying shear is generally suitable for occasions with large shear section and low shear speed. Its shear positioning accuracy is greatly affected by the control air source, solenoid valve and clutch brake friction plate. When the rolling speed changes greatly, it will have a certain impact on the shear length, which is generally solved by several shear tests.

7 conclusion

The flying shear control system composed of PLC has few devices, stable operation, low failure rate and convenient maintenance. In actual production, when the grinding system is started, the sampling screw conveyor rotates reversely to return the residual materials remaining in the conveyor to the grinding system. After 30s, it runs forward and begins to continuously sample in the direction of the sampling station, After all samples are divided by the divider according to
