How to Solve the Problem of the Blocked Concrete Delivery Pump

| Posted in General Discussion on April 16, 2021 08:03am

输送混凝土泵又称 混凝土泵拖车,具有施工速度快,施工质量好,施工方便的优点。在实际使用中,混凝土输送泵的管道堵塞是一个普遍的问题,会影响质量并降低效率.MINLE品牌的混凝土输送泵系统经过特殊设计和工程设计,可稳定运行并防止混凝土管堵塞。

为什么混凝土输送泵堵塞?

1.材料有问题。它主要包括三个方面,例如混凝土的偏析,集料的体积太大以及剩余量的控制不当。

  • 在混合混凝土中,粗骨料和细骨料没有被水泥浆覆盖,胶凝作用不足,因此骨料更加分散,很容易引起渗出。因为没有形成有效的润滑膜,所以骨料和管道之间的摩擦以及骨料和骨料之间的摩擦力增加。
  • 粗聚合配置是不合理的。其中,预定范围,混凝土的整体流动性越差。
  • 对剩余物料的控制不足低于搅拌轴,这会导致吸入空气和管道两端。

2.混凝土输送泵出了点问题。它主要包括两个方面,例如输送管道的泄漏和管道的不完全清洁。

  • 如果管道的泄漏不良,则由于水泥浆的泄漏,体积的泄漏将导致混凝土的流动性差,并且摩擦将导致管道的堵塞。
  • 在完成之前的泵送后,未按照规定清洁输送管道,从而导致管道畅通,从而影响了泵送。
  • 这两个问题在肘部都特别严重。

3.混凝土输送泵的管理问题。它主要包括三个方面:速度过快,间歇时间过长,对温度影响的考虑不足。

  • 在第一次泵送期间,泵没有适当的减速,这导致导管内部过度摩擦并连接了管道。
  • 暂时时间过长,导致混凝土在管道中达到初始凝固状态,从而导致后续的泵送并导致管道堵塞
  • 对温度影响的考虑不够充分,对导管的保护不当,导致水的过度蒸发或冻结,从而导致堵塞。

    如何防止混凝土输送泵制动?

     

    1.精心挑选的材料

    卵石的最大尺寸应小于输送管直径的1/3,碎石的最大尺寸应小于输送管直径的1/4,且含砂量应大于低于40%的量应足够,并保持在搅拌轴上方。注意检查混凝土的坍塌度。那些不合格的人必须在第二次混合后使用它。通常为8-18cm,距离长而高度大时通常为15cm。

     

    2.严格控制混凝土输送泵

    泵送时,请专人检查导管的密封性,并立即发现并修复泄漏。抽气完成后,您必须清洁导管并请专人检查和监督。每次抽水之前,请检查输送管道是否畅通。部双重。

    3.严格管理

    第一次,缓慢抽气,并在正常抽气后适当加速。通常,泵每5分钟打开一次,以防止在间歇时间段内管道分开。达到初始凝固状态的混凝土无法泵送。将吸管袋盖在管道外面,以控制夏天的温度和水。冬季降温并盖上保温层。
