我们在使用自动上料搅拌车的时候难免会出现一些问题,若是自动上料搅拌车堵管了应该怎样处理呢?下面就是小编为大家整理的方法。
When we use the automatic feeding mixer, we will inevitably have some problems. If the automatic feeding mixer is blocked, how to deal with it? The following is a small compilation of the method for everyone.
正常情况下,混凝土在泵送管道中心形成柱状流体,呈悬浮状态流动。流体表面包有一层水泥浆,水泥浆层作为一种润滑剂与管壁接触,骨料之间基本上不产生相对运动。当粗骨料中的某些骨料运动受阻,后面的骨料运动速度因受影响而渐渐滞缓,致使管道内粗骨料形成集结,支撑粗骨料的砂浆被挤走,余下来的间隙由小骨料填补。这样,骨料密度增大,使该段管道内集合物沿管道径向膨胀,水泥浆润滑层被破坏,运动阻力增大,速度变慢,直至运动停止而产生堵塞。
Under normal conditions, the concrete in the center of the pumping pipeline forms a columnar fluid, which flows in a suspended state. There is a layer of cement slurry on the surface of the fluid. As a lubricant, the cement slurry layer contacts with the pipe wall, and there is no relative movement between the aggregates. When the movement of some aggregates in the coarse aggregate is blocked, the movement speed of the later aggregate gradually slows down due to the influence, resulting in the accumulation of coarse aggregate in the pipeline, the mortar supporting the coarse aggregate is squeezed away, and the remaining gap is filled by small aggregate. In this way, with the increase of aggregate density, the aggregate in the pipeline will expand along the radial direction, the cement slurry lubrication layer will be damaged, the movement resistance will increase, and the speed will slow down until the movement stops, resulting in blockage.
自动上料搅拌车堵管的原因:混凝土配比不良、砂的粒径不合理、异物堵管。
The reasons for pipe blockage of automatic feeding mixer are: poor concrete ratio, unreasonable particle size of sand and blockage of pipe by foreign matters.

自动上料搅拌车堵管的解决办法:
Solutions for pipe blockage of automatic feeding mixer:
在一边进行泵送一反泵操作,一边沿管路检查时,可以用小锤敲打被认为是堵塞的部位,有时可使堵塞的骨料瓦解而恢复畅通:若敲打无效,则不准再用铁锤或其他可能伤害管道的物件重击。
During the operation of pumping and reverse pump while checking along the pipeline, small hammer can be used to knock the part which is considered to be blocked. Sometimes, the blocked aggregate can be disintegrated and unblocked again. If the knocking is ineffective, it is not allowed to use hammer or other objects that may damage the pipeline.
如果堵塞部位判断得准确,而且堵塞处离管道卸料的末端不远时,只要把堵塞段管件拆下,清除其中已堵塞的混凝土,再装回去,即可继续泵送。
If the blocking position is judged accurately, and the blockage is not far from the end of the pipe discharge, as long as the blocked pipe fittings are removed, the blocked concrete is removed, and then the pumping can be continued.
堵管部位在管道拆开时很容易判断;只要进行泵送操作,从拆开的管口有混凝土流出,则说明拆开部位与棍凝土输送泵之间无堵塞,应继续检查直至找到堵塞部位。如果堵管部位离管道端较远,堵塞段被清理后回装到管路,由于这段空管的气塞作用,也会造成再次堵塞。在这种情况下,应将堵塞段以后的管道混凝土用压缩空气吹出再接管泵送。如果堵管部位不能迅速判断或者难以拆卸时,应采用气洗方法把混凝土吹除,在堵管的情况下,往往需要分段吹洗。
The plugging position is easy to judge when the pipeline is disassembled; as long as the pumping operation is carried out and there is concrete flowing out from the disassembled pipe orifice, it indicates that there is no blockage between the disassembled part and the rod concrete delivery pump, and the inspection shall be continued until the blocked part is found. If the plugging part is far away from the end of the pipe, the blocked section will be installed back to the pipeline after being cleaned up. Due to the air plug effect of this empty pipe, it will also cause re blockage. In this case, the pipe concrete after the blocking section should be blown out with compressed air and then connected to pump. If the plugging position can not be quickly determined or it is difficult to dismantle, the concrete should be blown out by air washing. In case of pipe plugging, it is often necessary to blow the concrete in sections.

若分成较短的管段也吹洗不动时,要尽快组织人力,把全部管道逐节拆卸,清除其中的混凝土,并用水冲洗干净。
If the short pipe section can not be blown, manpower shall be organized as soon as possible to dismantle the whole pipe section by section, remove the concrete in it and flush it with water.
自动上料搅拌车堵管的原因以及处理的方法就是上面这些,大家在发现自动上料搅拌车的管堵了千万不要慌张,大家可以使用上面这些方法来解决。如果还有不明白的问题欢迎来电详询。
