棒材线定尺机液压系统的故障处理及优化

The Fault Handling and Optimization of the Hydraulic System of Shear Gauges in the Bar Production Line

棒材线定尺机投入使用1个月内出现多次液压缸连杆脱开故障，通过对定尺机液压系统分析，进行优化改进，增设减压阀和单向节流阀，合理控制供油压力和速度，降低液压冲击，消除了设备故障。

For the shear gauge of bar production line, the connecting rod disconnect failure of hydraulic cylinder appeared more than once within one month after putting into use, then through analysis on the hydraulic system of shear gauge, the corresponding optimization was carried out, including the adding of pressure reducing valves and one-way throttle valves and the reasonable control of oil pressure and speed, and thus the hydraulic impact was reduced, and the equipment failure was eliminated.
