    混凝土輸送泵如何配合攪拌機進行操作?

    操作人員精力不集中
    The operator is not focused
    輸送泵操作人員在泵送施工中應精力集中,時刻注意泵送壓力表的讀數,一旦發現壓力表讀數突然增大,應立即反泵2-3個行程,再正泵,堵管即可排除。若已經進行了反泵(正泵幾個操作循環,仍未排除堵管,應及時拆管清洗,否則將使堵管更加嚴重。
    During the pumping construction, the pump operator should pay attention to the reading of the pumping pressure gauge at all times. Once the reading of the pressure gauge suddenly increases, the pump should be reversed for 2-3 strokes immediately, and then the pump should be straightened, and the pipe blockage can be eliminated. If the anti pump (positive pump) has been operated for several cycles and the pipe blockage has not been eliminated, the pipe should be removed and cleaned in time, otherwise the pipe blockage will be more serious.
    泵送速度選擇不當
    Improper selection of pumping speed
    泵送時,速度的選擇很關鍵,操作人員不能一味地圖快,有時欲速則不達。首次泵送時,由于管道阻力較大,此時應低速泵送,泵送正常后,可適當提高泵送速度。當出現堵管征兆或某一車混凝土的塌落度較小時,應低速泵送,將堵管消滅在萌芽狀態。
    When pumping, the choice of speed is very critical, the operator can not blindly map fast, sometimes speed is not up to. When pumping for the first time, due to the large pipeline resistance, it should be pumped at a low speed. After the pumping is normal, the pumping speed can be appropriately increased. When there is a sign of pipe plugging or the slump of a truck of concrete is small, it should be pumped at low speed to eliminate the pipe plugging in the bud.
    自動上料攪拌車
    余料量控制不適當
    Improper control of surplus material
    泵送時,操作人員須隨時觀察料斗中的余料,余料不得低于攪拌軸,如果余料太少,極易吸入空氣,導致堵管。料斗中的料也不能堆得太多,應低于防護欄,以便于及時清理粗骨料和超大骨料。當某一車混凝土的塌落度較小時,余料可低于攪拌軸,控制在“S”管或吸入口以上,以減小攪拌阻力、擺動阻力和吸入阻力。本辦法僅適用于“S”閥系列混凝土泵。
    When pumping, the operator must observe the residual material in the hopper at any time, and the residual material shall not be lower than the mixing shaft. If the residual material is too small, it is easy to inhale air, resulting in pipe blockage. The material in the hopper should not be piled too much, and should be lower than the protective fence, so as to clean the coarse aggregate and super large aggregate in time. When the slump of a truck concrete is small, the surplus material can be lower than the mixing shaft and controlled above the "s" pipe or suction inlet to reduce the mixing resistance, swing resistance and suction resistance. This method is only applicable to "s" valve series concrete pump.
    混凝土的塌落度過小時采取措施不當
    Improper measures should be taken when concrete collapses
    當發現有一斗混凝土的塌落度很小,無法泵送時,應及時將混凝土從料斗底部放掉,若貪圖省事,強行泵送極易造成堵管。切忌在料斗中加水攪拌。
    When it is found that the slump of a bucket of concrete is very small and cannot be pumped, the concrete should be discharged from the bottom of the hopper in time. If it is greedy to save trouble and forced pumping, it is easy to cause pipe blockage. Do not add water to the hopper.
    停機時間過長
    Long downtime
    停機期間,應每隔5-10min(具體時間視當日氣溫、混凝土塌落度、混凝土初凝時間而定)開泵一次,以防堵管。對于停機時間過長,已初凝的混凝土,不宜繼續泵送。
    During the shutdown period, the pump should be started every 5-10 minutes (the specific time depends on the temperature of the day, concrete slump and initial setting time of concrete) to prevent pipe blockage. It is not suitable to continue pumping the concrete that has been stopped for a long time and has set initially.
    管道未清洗干凈
    Pipeline not cleaned
    次泵送完畢,管道未清洗干凈,會造成下一次泵送時堵管。所以每次泵送完畢一定要按照操作規程將輸送管道清洗干凈。
    If the pipeline is not cleaned after the first pumping, the next pumping will be blocked. Therefore, after each pumping, the pipeline must be cleaned in accordance with the operating procedures.
