混凝土自上料攪拌車堵管的三大原因
我們?cè)谑褂没炷磷陨狭蠑嚢柢嚨臅r(shí)候難免會(huì)出現(xiàn)一些問題,若是混凝土自上料攪拌車堵管了應(yīng)該怎樣處理呢?下面就是混凝土自上料攪拌車廠家為大家整理的方法。
When we use the concrete self-feeding mixer truck, we will inevitably encounter some problems. What should we do if the concrete self-feeding mixer truck is blocked? The following is how the manufacturer of the concrete self-loading mixer truck sorted it out for you.
正常情況下,混凝土在泵送管道形成柱狀流體,呈懸浮狀態(tài)流動(dòng)。流體表面包有一層水泥漿,水泥漿層作為一種潤(rùn)滑劑與管壁接觸,骨料之間基本上不產(chǎn)生相對(duì)運(yùn)動(dòng)。當(dāng)粗骨料中的某些骨料運(yùn)動(dòng)受阻,后面的骨料運(yùn)動(dòng)速度因受影響而漸漸滯緩,致使管道內(nèi)粗骨料形成集結(jié),支撐粗骨料的砂漿被擠走,余下來的間隙由小骨料填補(bǔ)。這樣,骨料密度增大,使該段管道內(nèi)集合物沿管道徑向膨脹,水泥漿潤(rùn)滑層被破壞,運(yùn)動(dòng)阻力增大,速度變慢,直運(yùn)動(dòng)停止而產(chǎn)生堵塞。
Under normal conditions, the concrete forms a columnar fluid in the center of the pumping pipeline and 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 the pipe wall, and there is basically no relative movement between the aggregates. When the movement of some aggregates in the coarse aggregate is blocked, the movement speed of the subsequent aggregates will gradually slow down due to the impact, resulting in the formation of aggregates in the pipeline, the mortar supporting the coarse aggregate is squeezed out, and the remaining gap is filled by small aggregates. In this way, the aggregate density increases, which makes the aggregates in the pipeline expand radially along the pipeline, the cement slurry lubrication layer is damaged, the movement resistance increases, and the speed slows down until the movement stops, resulting in blockage.
