Abstract
Pada perawatan secara tradisional untuk mengetahui
kerusakan yang terjadi pada suatu mesin dilakukan dengan cara
membongkar mesin,memeriksanya dan merakitnya kembali. Cara
ini menimbulkan down time yang panjang yang seringkali
sekedar untuk memeriksa mesin dan kondisi mesin itu
sendiri.Teknologi modern memungkinkan untuk menentukan
kondisi mesin dari luar tanpa harus membongkar mesin itu
sendiri.Yang paling efektif dari berbagai cara adalah analisis
getaran.Pengamatan tingkat getaran secara berkala dilakukan
untuk mengetahui sesuatu yang tidak normal dan dideteksi
sebelum kerusakan yang lebih fatal terjadi.
Alat vibrasi Computational System Incorporated (CSI)
2130 mempunyai kemampuan untuk mengkonversikan dari
domain waktu ke dalam domain frekuensi yang nantinya berguna
untuk mengidentifikasi sumber kerusakan.Maka dilakukan
pengukuran vibrasi pada mesin Boiler Feed Water Pump.Melihat
level getaran,dan karakteristik (domain frekuensi) dari
pengukuran disimpulkan bahwa mesin diprediksi mengalami
kerusakan pada bearingnya.
Setelah proses perbaikan dilakukan,maka dilakukan
pengujian vibrasi lagi.Hasil pengukuran vibrasi menunjukkan
mesin mengalami penurunan level getaran,namun masih ada
nilai rms tinggi pada titik pengambilan PIH.Maka disimpulkan
mesin diprediksi masih ada masalah pada bagian PIH.Untuk itu
perlu dilakukan perbaikan kembali. ========== In the traditional treatments to determine the damage
that occurs in an engine made by dismantling the engine, inspect
and reassemble. This imposes lengthy down time often just to
check the condition of the machine and the machine itself.
Modern technology makes it possible to determine the condition
of the engine from the outside without having to disassemble the
machine itself. The most effective of the various ways is vibration
analysis. Observations vibration levels periodically conducted to
determine something that is not normal and detected before
damage occurs more fatal.
Tool vibration Computational Systems Incorporated
(CSI) in 2130 has the ability to convert from the time domain to
the frequency domain that would be useful to identify the source
of the damage. Then the measurement of vibration on the engine
Boiler Feed Water Pump. Seeing the level of vibration, and
characteristics (frequency domain) of the measurement is
concluded that the predicted engine suffered damage to his
bearing.
After the repair process is done, then the vibration testing
again. Engine vibration measurement results showed decreased
levels of vibration, but there is still a high rms value at the point
of making PIH. It is concluded predictable machine there are still
problems in the PIH. It is necessary for restoration.
