翻钢机液压系统的设计分析

翻钢机液压系统设计流量小、电机功率低,不能满足运行速度要求;油箱温度控制不合理,易造成泵气蚀和液压油被局部加热;滤芯精度等级选用不当,造成系统污染引起故障;同步回路设计易造成累计误差。通过分析计算重新选取泵、电机,按照泵运行对油黏度要求控制油温,按照工况选取滤芯精度等级,重新设计同步系统消除累计误差。翻钢机经过设计优化,运行平稳,延长设备使用寿命,减少了设备故障。

Design and Analysis of Hydraulic System for Tilter

The low discharge and motor power of hydraulic system for slab tilter cannot meet the requirement of running speed; the inconsequent temperature control of tank will cause cavitation erosion to the pump and local heating to the hydrau- lic oil; the improper selection of filter core level will cause the system to be polluted and go wrong; and synchronizing circuit design will cause integrating error. In this paper, the pump and motor were reselected through analysis and calculation, oil temperature was controlled according to the request when the pump was running, the filter core level was selected according to the working conditions, and synchronizing circuit system was redesigned to eliminate integrating error. The slab tilter runs smoothly, thus the service life is prolonged, and the equipment fault is reduced by these optimization designs.
