The market demand for concrete pump trucks is slowly increasing with the development of the construction industry. Many customers lack experienced pump drivers after purchasing pump trucks. In fact, the various functions of the new pump truck can be said to be in a very good condition, but the best concrete pump truck will have a running-in period with the pump driver at the beginning of use.

1. Fast wear

The impact of factors such as the processing, installation and adjustment of the new machine parts of the pump truck has a rough appearance, the touch area of the cooperation surface is small, and the appearance of pressure is uneven. During the operation of the pump truck, the concave and convex parts of the parts surface interfit and conflict with each other, and the metal scraps that fall off are used as abrasives to continue to participate in the conflict, which accelerates the wear of the parts in cooperation. Therefore, during the running-in period of the concrete pump truck, abrasion of parts (especially the appearance of cooperation) is simply formed, and the wear rate is fast. At this time, if overloaded work is done, it may cause damage to the parts and early failures.

  2. Poor lubrication

The cooperation gap of the newly installed parts of the pump truck is small, and because of installation and other reasons, it is difficult to ensure the uniformity of the cooperation gap. The smooth oil (grease) is not easy to form a uniform oil film on the surface of the conflict to prevent wear. Then the smoothing efficiency is reduced, and the abnormal wear of the mechanical parts is formed in the early stage. When it is severe, it will form the phenomenon of scuffing or occlusion of the appearance of the conflict of fine cooperation, leading to the onset of the failure of the concrete pump truck

 3. Loose

The newly processed and installed parts of the concrete pump truck have some deviations in shape and cooperation dimensions. In the early stage of use, they are affected by alternating loads such as impact and vibration, as well as heat, deformation and other factors, as well as excessive wear and tear. , Simply loosen the originally fastened parts.

 4. Leakage occurs

Due to the loosening and vibration of the machine and the influence of the machine being heated, the sealing surface of the machine and the pipe joints will show leakage; some defects such as casting and processing are difficult to find during installation and debugging, but because of the vibration during the operation , Impact action, this shortcoming is exposed, manifested as leakage (seepage) of oil (water). Therefore, the pump truck simply exhibits leakage during the running-in period.

 5. Many operating errors

Because of the poor understanding of the structure and function of the machine (especially for new operators), simple operation errors may cause problems and even cause trouble.
