Abstract

This study investigates the predictive potential of specific vibration patterns in assessing the structural integrity of centrifugal pumps, vital for industrial fluid transport. Despite their importance, these pumps often encounter performance issues attributed to vibration-related damage such as cavitation and corrosion. Addressing this gap, we employ advanced vibration analysis techniques to identify distinct signatures indicative of cavitation and corrosion progression. Our research aims to provide an early detection tool for maintenance by understanding these patterns. Through our method, we reveal significant correlations between vibration patterns and pump condition, offering implications for extending pump lifespan and enhancing maintenance strategies in industries reliant on such machinery. Highlights: Centrifugal Pump Operation: Impeller rotation transfers fluid. Vibration Analysis Significance: Essential for predictive maintenance. Cavitation and Corrosion Effects: Trigger vibration, erode surfaces. Keywords: Centrifugal Pump, Corrosion, Vibration

Abstract

Boundary layer adalah lapisan batas yang terbentuk akibat gesekan antara permukaan penampang dan fluida, sehingga terjadi gradiensi kecepatan. Penelitian ini mengamati gradiensi kecepatan fluida pada boundary layer dalam pipa lurus menggunakan metode eksperimental. Distribusi kecepatan fluida diukur menggunakan pipa akrilik berdiameter 1” dan jarum tumpul berdiameter 1,5 mm yang menyerupai tabung pitot dengan sistem perbedaan tekanan stagnasi dan tekanan statis. Fluida dengan berbagai viskositas dan laju aliran diuji untuk memahami pengaruhnya terhadap karakteristik lapisan batas. Dengan flowrate 10 liter/menit menunjukkan hasil pengukuran kecepatan fluida meningkat seiring bertambahnya jarak radial pada dinding pipa mulai dari =2 mm (0,334 m/s), =5,5 mm (0,341 m/s), =7,5 mm (0,425 m/s), =10,5 mm (0,438 m/s), dan pada =12,7mm (0,443 m/s). Kecepatan tertinggi tercatat di titik tengah pipa yang membuktikkan bahwa hasilnya sesuai dengan karakteristik boundary layer, di mana gaya gesekan dan viskositas berkurang.
