  • Rotork SPI keeps plant control systems reliably informed of manual valve positions

    Refinery operators have a pressing requirement to improve the efficiency of flow control in their plants and they want to know from the Distributed Control System (DCS) if valves are open or closed. In a typical refinery, 10% of valves are actuated and 90% are manually operated. This poses a serious problem for end-users if the DCS does not accurately know how many manual valves are opened or ...

  • Trailer pump operation and performance (part 3 of 3)

    System Curves Just as a plot can be made of pump performance, a graph can be made of the resistance to flow of the piping system through which the pump must drive the fluid. Using the same head-flow coordinates as the pump performance curve, the figures below can be created. The curve in Figure 1 represents a system in which there is no static head. The curve in Figure 2 shows the loss ...
