请问泵管堵塞了应该如何处理呢? - 工程施工 - 项目管理 - 氿上知道

满意答案
泵管发生堵塞时,应尽快确定其堵塞位置,并加以排除,以避免停歇时间过长而带来更大的困难。泵管堵塞的位置应根据泵机类型来确定。
1. 机械式泵 重新启动泵短时间运转,由于堵塞所引起的阻力会使堵塞点与泵机之间的管道产生显著振动,过了次点的管道责是静止的。如采用这种方法得不到肯定的结果,就将泵停止工作,并从泵的一端开始,对管道的接头逐个进行检查,稍微放松第一节管子接头,如砂浆在压力下冒出来,说明这一节并不堵塞,重新拧紧接头,说明这个接头至前一接头,如此逐个检查,直到发现压力较小的管子接头,说明这个接头至前一个接头之间是堵塞的。
2. 液压式泵和挤压式泵 暂时使泵逆转,可使混凝土回流,然后再使泵恢复正常运转,如果不见效,责连续做逆转和顺转操作,如果多次试验仍不能见效,可按机械式泵的方法进行检查。(这里补充一点:有经验的泵工会通过锤子击打泵管来判断堵塞的位置)
清楚堵塞物的程序:卸下堵塞的泵管,并用人工清楚;将这段泵管重新接在泵的出料口再开动泵,使这段泵管充满混凝土拌合物;最后将这段泵管与其他泵管连接,恢复正常工作。
