How to improve the efficiency of concrete pump trailer

To improve the efficiency of concrete pump trailer, the pumping work should be performed as continuously as possible. The piston of the concrete pump cylinder should be kept running at the maximum stroke in order to exert the maximum efficiency of the trailer concrete pump and make the concrete cylinder wear uniform in the length direction.



Before pumping concrete, first pumping clean water into the pipeline, check the pipe clamps to ensure that the seal is not leaking, and then pump the pipeline lubricant. Generally, mortar or cement slurry can be used. Pour the mortar into the hopper for pressure feeding. When the mortar is about to be fed, you can pour the concrete that meets the requirements for normal pressure feeding. If the mortar pressure is blocked, you can remove the foremost pipe and dewater the block inside. Take out, connect the piping, and it can run normally.

 When the trailer concrete pump is running, do not put your hand into the hopper or water tank. During the pumping process, the concrete material should be ensured above the mixing axis, and no suction or no material pumping is allowed. If the concrete pumping work is suspended for a long time, the pump must be turned on every (15 -30) min, the reverse pump 1-2 strokes, and then the forward pump 1-2 strokes to prevent the concrete in the pipe from condensing.

After the pumping is completed, the hopper and the conveying pipe system must be carefully cleaned. If the residual concrete in the concrete cylinder is not cleaned, it will solidify on the cylinder wall. When the piston runs again, the sealing surface of the concrete pump trailer piston will directly withstand the impact of the solidified concrete on the cylinder wall, which will cause the piston to partially peel off. This kind of damage is different from the normal wear of the piston seal. The sealing surface cannot compensate for itself under the pressure, resulting in slurry leakage or air suction, causing pumping weakness and blockage.
