针对LWZ1400×2000A卧式沉降离心机控制系统在运行中存在启动电流过大、供电不稳定及接线复杂的问题,通过现场试验研究,将原继电器+接触器转换控制方式改造为触摸屏+PLC控制软启动器的联合控制方式。实践表明,触摸屏+PLC控制软启动器的联合控制系统的应用,有效保证了LWZ1400×2000A卧式沉降离心机的安全平稳运行。
In view of LWZ1400 × 2000A horizontal sedimentation centrifuge control system in the operation of the existence of the starting current is too large, unstable power supply and wiring problems, through the field test research, the original relay + contactor conversion control method for the touch screen + PLC control software Starter joint control. Practice shows that the touch screen + PLC control soft starter application of the joint control system, effectively ensure the LWZ1400 × 2000A horizontal settlement centrifuge safe and stable operation.
