The drilling pump is one of three major parts of a drilling rig, and is the key equipment of the drilling fluid circulation system. In this paper, the reliability of a ZCL-1600-type drilling mud pump pressure cylinder of the hydraulic system is carried on the thorough discussion. The reliability block diagram is established by qualitative analysis and quantitative calculation.

Learn MoreWhile there is no consensus yet as to a precise definition of this term, mathematical modeling is generally understood as the process of applying mathematics to a real world problem with a view of understanding the latter. One can argue that mathematical modeling is the same as applying mathematics where we also start with a real world problem, we apply the necessary mathematics, but …

Learn MoreConcrete pump booms are subjected to vibrations that increase mechanical stress and shorten their lifespan. This paper aims to study the problem by considering the two subsystems, the boom and the concrete pump, that have the greatest effect on the phenomenon. The authors supply numerical and experimental tools that can analyze the problem in depth in all its complexity.
