Abstract

Water hammer is pressure fluctuation caused by sudden increase and decrease in flow velocity. At Papa Flow Station, water hammer occurs in the slop-pump pipeline network that use level controller operating system. The pressure fluctuation caused by water hammer can damage pipeline or shorten the life of the components. This research was conducted using AFT Impulse software to simulate the modeling. The results showed the gas accumulator could reduce the pressure oscillations on check valve to 1.5 oscillations. The gas accumulator installation alone did not have a significant effect on reducing the fluctuation from the highest pressure of 70 psi. Adding a check valve on the tie-in header-downstream of the pump combined with the installation of a gas accumulator can reduce pressure fluctuations from a maximum of 70 psi to 15 psi and the pressure oscillation will stabilize after the second second when the pump trips at 11 psi. Keywords: cavitation, water hammer, pressure oscillation, pressure fluctuation, gas accumulator DOI: 10.7176/JETP/10-5-03 Publication date:September 30th 2020
