摘　　要：为了保证螺旋焊管机组递送机压下系统保压回路的正常运行,使得钢板平稳匀速进入到焊接工位,对递送机压下系统保压回路的失效原因做了分析。分析表明,在实际生产中,递送机压下系统蓄能器保压回路故障引起的上辊压力不足、不稳现象是造成钢板递送动力不足,带钢跑偏的主要原因。在对保压回路失效原因进行分析的基础上,给出了故障排除方法,指出在应用中应根据保压回路的具体故障现象,通过检测分析,准确找出故障原因,快速排除。In order to guarantee the normal operation of spiral welded pipe delivery machine screw-down system pressure maintaining circuit, make steel plate smoothly enter into to the welding station at a constant speed. In this article, it analyzed the failure reason of screw-down system pressure maintaining circuit, it is concluded that in practical production, the insufficient and instability pressure of upper roller caused by system accumulator pressure maintaining circuit fault was the main reason of steel plate delivery underpowered and deviation. The failure removal methods were given. In actual application, on the basis of the specific fault phenomenon, it should accurately find failure reason through detection analysis, and quickly eliminate.
