    27/7/2012 · With time, the pressure slightly increases as more concrete is inserted in the pipes. Suddenly, the pressure rises up to 55 bar, as the concrete blocks in the pipe. The pumping is consequently stopped and a front of aggregates, similar to the one depicted in Fig. 1 (right), must be removed before continuing.

    11/2/2020 · One takes in the water for your usage, and the other takes out the water, which has already been used for the whole concrete pumping. For the water which is taken out, the pressure is much less here. Since the water which comes in is allowed to work upstairs, around the corners, and someplace else at the house, the water is going against the force of gravity.

  • PUMPABLE CONCRETE AND CONCRETE PUMPING - ScienceDirect

    If the pump is mechanically sound, the failure of concrete to emerge at the end of the pipe line is called blockage. The increase in the pressure shown by the pressure gauge of the pump is the indication of the blockage of the pipe line. Most blockages take place or occur at the tapered sections of the pump end.

    17/12/2011 · The more efficient the piping and pumping system, the more the pressure energy can be used to actually move the fluid. If the piping system is restrictive in some way (undersized and/or excessively long with unnecessary turns or valves) much of the pump's energy is wasted attempting to overcome these limitations.

  • Pump - Wikipedia

    A pump is a device that moves fluids (liquids or gases), or sometimes slurries, by mechanical action, typically converted from electrical energy into hydraulic energy. Pumps can be classified into three major groups according to the method they use to move the fluid: direct lift, displacement, and gravity pumps.[1] Pumps operate by some
