Abstract
Pada sistem penyaluran bahan bakar pesawat (avtur) di rumah pompa fase 3 DPPU Ngurah Rai menggunakan 6 pompa beroperasi dengan 6 variasi berbeda mulai 1 pompa dioperasikan sampai 6 pompa semua dioperasikan secara bersamaan. Pada 6 variasi ini timbul fenomena backpressure yang di sebabkan oleh aliran fluida transient yang mengalami gaya aksi-reaksi yang terjadi di dalam pipa sepanjang jalur penyaluran avtur. Hal ini menimbulkan kerusakan pada absorber yang mengalami backpressure yang tidak terkontrol dengan baik. Untuk membuktikan hal ini, pada penelitian ini dilakukan 6 skenario operasi dimana, pada setiap skenario menggunakan nilai pressure dan volume yang ada pada setiap absorber yang terpasang pada head suction pump sebagai acuan. Dengan parameter di atas di dapat bahwa pada setiap absorber mengalami backpressure untuk semua skenario operasi dengan kondisi operasi 2 jam. Variasi pertama pada menit ke 54, variasi kedua menit ke 55 dan 58, variasi ketiga menit ke 56, 62, dan 66, variasi keempat menit ke 57, 66, 74, dan 79, variasi kelima menit ke 58, 69, 81, 91, dan 95, variasi keenam menit ke 59, 72, 86, 101, 111, dan 119. Untuk mencegah hal ini maka, dilakukan re-design absorber.=============================================================================================================
In the aircraft fuel distribution system (avtur) on the pump house phase 3 DPPU Ngurah Rai using 6 pumps operate with 6 different variations from 1 pump operated to 6 pumpsl operated simultaneously. In these 6 variations backpressure phenomena happened caused by the transient fluid flow experiencing the action-reaction force occurring on the pipe along the avtur channel path. This causes damage to the absorber that has backpressure that is not well controlled. To prove this research, 6 scenarios of operation are performed in this scenario where each scenario uses the pressure and volume as values in each absorber attached to the head suction pump for reference. With the above parameters obtained that at each absorber backpressure for all operating scenarios with operating conditions 2 hours. The first variation in the 54th minute, the second variation in the 55th and 58th minutes, the third-minute variations in 56, 62, and 66, the fourth-minute variations in 57, 66, 74, and 79, the fifth minute variations in 58, 69, 81, 91 , and 95, variations of six minutes in 59, 72, 86, 101, 111, and 119. To prevent this, re-design absorber needed.
