Abstract

Pengukuran getaran umumnya dilakukan pada mesin yang sedang beroperasi tetapi ketika terdapat dua mesin atau lebih yang beroperasi dalam satu pondasi apakah hasil dari pengukuran benar- benar menggambarkan kondisi mesin. Sehingga diperlukan deteksi kerusakan pompa yang dipengaruhi transmissibilitas getaran pompa lain dalam satu pondasi menggunakan accelerometer array. Deteksi kerusakan dilakukan dengan mengukur getaran pompa yang berada pada satu pondasi. Dari hasil penelitian membuktikan bahwa transmissibility dapat dideteksi menggunakan accelerometer array dibuktikan dengan adanya perubahan diagnosa kerusakakn pompa yang dilihat pada spektrum Fast fourier transform. Nilai transmissibility yang bernilai negatif menunjukkan superposisi destruktif misalkan pada pompa misalignment 2mm (yang dioperasikan dengan pompa unbalance 27 gram.cm) dengan nilai transmissibility -7.7296 dB. Sedangkan transmissibility yang bernilai positif menunjukkan superposisi konstruktif misalkan pada pompa bearing fault (yang dioperasikan dengan pompa unbalance 27 gram.cm) dengan nilai 3.6719 dB. ============================================================================================================= Vibration measurement is generally performed on a running rotating machine but when there are two or more machines that operate in a foundation, if the results of the measurements really describe the condition of the engine. Therefore its necessary to detection of damage pump that affected from vibration transmissibility another pumps in a foundation using accelerometer array Detection of the damage performed by measuring the vibration of the pump that is at the foundation. From the results of the study prove that the transmissibility can be detected using an accelerometer arrays evidenced by the change in the pump damage diagnosis are seen in spectrum of the Fast Fourier Transform .Detection of the damage performed by measuring the vibration of the pump that is at a foundation. Transmissibility value that is negative indicates a destructive superposition example the pump misalignment of 2mm (which is operated by the pump 27 gram. cm) with result a value of -7.7296 dB transmissibility. While a positive value in transmissibility indicates that constructive superposition example the pump bearing fault (unbalance pump operated with 27 gram. cm) with a value of 3.6719 dB.
