螺旋縫焊管生產中遞送機打滑原因分析及解決措施

Analysis and Solution of Slipping of Delivery Machine during Production of Spiral Welded Pipes

摘要: 分析了螺旋縫焊管生產中遞送機打滑的原因，并提出解決措施。分析認為：對頭處焊縫余高過高、鋼板壁厚不均、管路泄漏或者蓄能器氮氣不足、遞送機液壓系統(tǒng)設計不合理等因素都會導致遞送機打滑；通過選擇合理焊接工藝參數、修磨焊縫余高、增大遞送機壓力、補充蓄能器氮氣、改進遞送機液壓系統(tǒng)等措施，可解決遞送機打滑。

Abstract: Analyzed in the article are the causes for slipping of the delivery machine during the manufacturing operation of the spiral welded pipe，and accordingly put forward are the countermeasures.Based on the analysis it is identified that factors responsible for the said delivery machine failure include over high excess weld metal at the butting area，steel plate uneven thickness，piping leakage，poor nitrogen supply to the accumulator，and unreasonable design of the machine’s hydraulic system.The countermeasures as proposed for fixing the slipping problem are proper determination of the weld process parameters，grinding the over high excess weld metal， increasing the delivery pressure，ensuring sufficient nitrogen supply to the accumulator，and modifying the delivery machine’s hydraulic system，etc.
