摘要
多点同步顶升系统是为大吨位重物提升和下放提供精确位移控制的产品;其通过可编程逻辑控制器接收安装在千斤顶旁且与重物相连的传感器发出的信号,然后处理信息并发送控制信号到各液压缸控制阀,打开或关闭高频/速控制阀来提升和下放重物,且确保各提升点的同步误差保持在操作者设定的范围。
Multi-point synchronous jacking system is designed to provide accurate displacement products for lifting and lowering large tonnage heavy objects;the programmable logic controller receives signals from the sensor installed next to the jack and connected with the heavy object,then processes the information and sends control signals to each hydraulic cylinder control valve,opens or closes the high-frequency/speed control valve to lift and lower heavy objects,and ensures that the synchronization error of each lifting point is kept within the range set by the operator.
