It is a confusing thing to encounter the mortar spraying machine's pipe blocking during construction. It not only delays the construction period, but also takes a lot of trouble to deal with, and even comes with a risk situation. Now we have collected various treatment methods for pipe plugging, let you destroy the pipe plugging problem of mortar spraying machine! The operator's energy will not be concentrated, and the operator of the delivery pump should concentrate on the pumping construction.
Time to pay attention to the reading of the pumping pressure gauge. Once it is found that the reading of the pressure gauge suddenly increases, you should immediately reverse the pump 2-3 strokes, then correct the pump, and the pipe can be removed. If the reverse pump has been carried out (the positive pump has several operation cycles, and the blocked pipe has not been removed, the pipe should be removed and cleaned in time, otherwise the blocked pipe will become more severe.
The pumping speed is not properly selected. When pumping, the speed selection is very important. The operator cannot blindly map fast, sometimes the speed is not reached. When pumping for the first time, the pump should be pumped at a low speed because of the large resistance of the pipeline. After the pumping is normal, the pumping speed can be appropriately increased. When there is a sign of pipe plugging or the concrete slump of a certain vehicle is small, it should be pumped at a low speed to eliminate the pipe plug in the germination state.
The amount of residual material is not properly controlled. When pumping, the operator must investigate the residual material in the hopper at any time. The residual material should not be lower than the mixing shaft. If the residual material is too small, it is easy to inhale air and cause pipe blockage. The material in the hopper should not be piled up too much, it should be lower than the protective fence, in order to facilitate the timely sorting of coarse aggregates and oversized aggregates. When the slump of the concrete of a certain vehicle is small, the remaining material can be lower than the mixing shaft, and be controlled above the "S" tube or suction inlet to reduce mixing resistance, rocking resistance and suction resistance.
