MINIMALISASI PENGARUH WATER HAMMER TERHADAP NILAI TEGANGAN DISCHARGE POMPA GM 53 JALUR CY.1 DENGAN PERBANDINGAN GAS ACCUMULATOR DAN SURGE ANTI VALVE
Abstract - Distribution of fuel oil uses pipeline to avoid water hammer, because it can inhibit distribution process. In the case study there was a water hammer at the discharge pump GM 53 line CY.1 pipe. This is caused by the sudden closing of the valve, so that the working pressure exceeds the maximum limit on the discharge pump. This study was conducted to determine the impact of water hammer pressure on pipeline stress and effective way to minimize the impact of water hammer. In this study shows the difference between the calculation of manual pressure increase and using software of 6.291%. From modeling to know the value of stress with normal condition and when water hammer difference of stress happened value 2777 Psi. In reducing the pressure spike is used the addition of accumulator and surge anti valve with pipenet modeling. The result of pipenet modeling shows more effective surge pressure of anti-valve surge in reducing the spike of pressure value.
