【摘要】 为了提高割缝筛管防砂效果,介绍了割缝筛管新型复合缝腔——台阶缝。根据台阶缝生产加工工艺要求,设计了满足台阶缝新加工工艺的生产设备——挤缝机及其液压系统。与以往的复合缝腔加工工艺比较,降低了生产成本,提高了加工效率。更多还原

【Abstract】 In order to improve the effect of slotting screen sand control,the slotted sieve tube new composite joint cavity step seam was introduced. According to the step seam production process requirements,squeeze machine and its hydraulic system were designed which met the new processing production equipment. Comparing with previous composite joint cavity processing technology,the production cost is reduced and the processing efficiency is improved.更多还原
