Pressure Analysis of Hydraulic Pumping System of Concrete ...

By means of power linkage chart method, the model of closed loop pumping system of concrete pump was set up and simulation was carried out in the Matlab. The results show that the hydraulic shock in the closed loop did not occur at the rapid commutation of piston pump and it actually happened when the concrete was pushed forward after compression.

Piston Pump - an overview ScienceDirect Topics

Andrew Parr MSc, CEng, MIEE, MInstMC, in Hydraulics and Pneumatics (Third Edition), 2011. Piston pumps. A piston pump is superficially similar to a motor car engine, and a simple single cylinder arrangement was shown earlier in Figure 2.2b.Such a simple pump, however, delivering a single pulse of fluid per revolution, generates unacceptably large pressure pulses into the system.
