This article provides you with some solutions for different failure scenarios.

1. Mixing shaft rotation failure

The concrete pump truck is driven by a hydraulic motor to drive the mixing shaft to feed the commercial concrete cylinder by secondary mixing of the commercial concrete. Once you find that the mixing shaft does not rotate or the speed drops significantly, you should immediately check whether the mixing hydraulic motor is working normally, whether the pressure of the mixing hydraulic system is within a reasonable range, or appropriately accelerate the speed of the mixing shaft.

2. Blockage and elimination of conveying pipes

Most of the parts where the concrete pump truck conveying pipe is blocked are in the cone pipe and bend that are easy to vibrate. You can beat it with a small iron rod along the conveying pipeline, if the sound is crisp and the conveying sound is rustling, it means that there is no blockage; If the sound is dull and the transmitted sound is harsh, it is a blockage. At this time, the conveying pressure gradually increases, the pumping action stops, the hopper material level does not drop, the pipeline outlet end does not discharge, the pump vibrates, and the pipeline mixes with strong vibration and displacement. The reverse pump is operable, but it becomes blocked after turning into the positive pump. If the commercial concrete boom pump truck conveying pipe is slightly blocked, then the blockage should be identified first, and then the commercial concrete should be loosened by shaking and hammer knocking, and the positive pump and reverse pump operations should be repeated, and the commercial concrete should be gradually sucked out into the hopper, and then it should be pumped after remixing. If the blockage problem cannot be eliminated through these measures, then the method of dismantling the pipe should be adopted to drain the commercial concrete blockage, and the conveyor pipe of the blockage can be taken over only after it is removed to avoid re-blockage.

3. Replace it in time

The life of each hydraulic pump or pump part is limited, and you should pay attention to regular accuracy inspection, regular inspection, regular maintenance, routine maintenance, as well as equipment cooling system maintenance and equipment lubrication system maintenance.
