磁致伸缩位移传感器船闸系统组成

  1、液压启闭机组成

  某船闸于2018年建成投用,闸、阀门启闭机采用直推式液压机型,闸门启闭机布置在上下闸首边墩的空箱内,阀门启闭机布置在二层机房内,每个闸首一侧的闸门和阀门启闭机共用一台泵站,泵站内部阀件采用PARKER公司产品。闸、阀门电机为ABB三相变频电机,功率分别为15、11kW。闸、阀门油泵均为PARKER恒压变量柱塞泵,排量分别为32ml/r和46ml/r。闸、阀门油缸均带博尔森磁致伸缩位移传感器,油缸内径为250mm,活塞杆外径为180mm,最大行程为4200mm(工作行程:闸门为4100mm;阀门为4000mm)。博尔森磁致伸缩位移传感器为RFM4300MD601R03型,其长度为4300mm,供电电压为24VDC,输出信号为4~20mA模拟量,接口形式为直出三米电缆。

  2、启闭机控制系统

  根据直推式液压机型、人字闸门运行方式以及输水系统灌、泄水要求,闸、阀门启闭机以变速方式运行。启闭机控制系统由上位机及2套施耐德PLC组成,实现对上、下闸首闸,阀门等机械设备的控制。每套PLC系统由一个主站和一个远程站组成,其中主站采用Schneider TSX Quantum系列PLC,远程站采用Schneider TSX Quantum系列RIO,两者通过专用电缆相连。控制系统的网络结构如图1所示。

磁致伸缩位移传感器船闸系统组成

  在闸门启闭机液压控制系统中,由ATV71HD15N4变频器控制电机频率改变电机和油泵的转速来实现无级变速,频率范围为18~50Hz。在启闭机启、闭过程中,变频器先以低频18Hz运行,并通过博尔森位移传感器实时检测油缸活塞杆运行位置;在闸门运行到某位置(总行程的10%,可调整)后,便开始逐步升至工频运行;待闸门运行到另一设定位置(总行程90%,可调整)后,再由高频逐步降至低频运行直至终点。正常情况下,闸门启、闭时间控制在3min以内。在运行过程中,博尔森磁致伸缩位移传感器实时检测油缸活塞杆行程情况,并通过组态软件在工控机上显示,以方便操作人员观测闸门运行状况。

  在阀门启闭机液压控制系统中,由ATV71HD15N4变频器控制电机频率改变电机和油泵的转速来实现无级变速。阀门开启时,电机先以0.7m/min的速度(频率为21Hz)运行lmin;随后2min,运行速度从0.7m/min缓升至1.5m/min;再以1.5m/min速度运行到位。强制关闭阀门时,电机以1. 84m/min(可调)的速度运行。阀门平水关闭时,采用差动回路。通过油缸内安装的博尔森磁致伸缩位移传感器,操作员可随时观察阀门运行情况。
