摘　　要：分析了双膛窑旋转料钟下行过程对窑体形成巨大冲击力的原因,优化了液压系统液压驱动装置,由定频电机泵改造为伺服驱动同步电机泵;采用基于S7-400的旋转料钟液压下行缓冲装置的改造方案,减小了料钟下降过程对窑炉的冲击,提高了窑炉电气仪表设备的运行稳定性。This paper analyzes the reason why the downward process of rotary bell of twin shaft kiln forms great impact force on the kiln body.The hydraulic driving device for hydraulic system is optimized,and fixed-frequency motor pump is transformed with servo-driven synchronous motor pump.The transformation scheme of hydraulic downward buffer device for rotary bell based on S7-400 is adopted,which reduces the impact of downward process of the bell on kiln and improves the running stability of kiln electrical instruments and equipment.
