摘要:
螺杆式启闭机在日常使用下降过程中螺杆被压弯的现象时有发生,其主要原因是水闸门槽或闸室底板有较大坚硬异物一般不易被运行管理人员察觉,若异物没有被及时清理,会导致闸门运行缓慢甚至停滞。现有的保护系统很难做到及时、精准的动作,可能会造成螺杆被不同程度地压弯。通过直接跟踪闸门实时位移速度这一途径,利用PLC快速精准测量速度,并在螺杆启闭机发生异常时及时断电停机,可有效避免上述现象的发生。
Abstract:
Screw hoist in the daily use of the decline process, the phenomenon of screw bending occurs from time to time. The main reason is that some large hard objects at the bottom of the sluice gate or the sluice gate groove are not easy to be detected by the operation management personnel. If the hard objects are not cleaned up in time, it will lead to slow or even stagnation of the sluice gate operation. The existing protection system is difficult to achieve timely and accurate action. As a result, the screw will be bent to different degrees. By directly tracking the real-time displacement speed of the sluice gate, using PLC to quickly and accurately measure the speed, and timely action to power down when the screw hoist is abnormal, the occurrence of the above phenomenon can be effectively avoided.
