In the construction of concrete pump, the weight of friction between mechanical metal and concrete is closely related to the speed of pumping, concrete label, and some specific formulations of concrete. For example, concrete contains more aggregates, and the ratio of sand to cement is relatively high. If it is less, then the friction force of the concrete pump will increase.

However, there is no stricter evidence to prove the relationship between the friction strength and the pumping speed of the concrete pump. It is only observed according to some of our common sense. Taking the piston movement inside the engine as an example, if the piston The faster the movement speed, the smaller the friction force should be. However, no matter what kind of relationship there is between these data, it is certain that this friction will cause multiple parts inside the concrete pump of wear.

During construction, the concrete pump starts feeding into the hopper, and this mutual friction begins. In addition, the mixing blades, hopper and some concrete in the hopper enter the concrete cylinder. Then enter the pipe, and finally enter each conveying pipe, The close contact and friction between the various parts of the concrete pump and the commercial concrete will eventually lead to a shortened service life between them.
