Vibration and Alignment Measurement and Analysis

BACKGROUND:

Vibration & miss-alignment merupakan salah satu kesalahan operasi yang menyebabkan kerusakan peralatan yang secara umum menurunkan efisiensi suatu plant. Untuk menghindari hal tersebut, diperlukan cara pengukuran, monitoring dan analisa data yang benar agar dapat diambil tindakan yang tepat guna menjaga efisiensi peralatan.

TRAINING OBJECTIVES:

• Improve Advance Vibration knowledge
• Understand how to select and use instrumentation to measure vibration correctly
• Detect The Mechanical Component Damage Prematurely & Make necessary anticipation 

COURSE OUTLINE: 

1. Getaran (Vibration)

• Anatomi Mesin Rotasi dan Getarannya
• Sensor dan Analyzer
• Cara Pengukuran Getaran
• Analisis Getaran dalam Domain Waktu dan Frekuensi
• Memanfaatkan Fasa untuk Analisis
• Mechanical Signature Analysis (karakteristik getaran kerusakan mesin seperti: ketakseimbangan (imbalance), bantalan gelinding (rolling bearings), bantalan luncur (sliding bearings), oil whirl & oil whip, misalignment, mechanical looseness, gear, blade & vane, resonansi, motor listrik (motor current signature analysis).

2. Metode Analisis Sinyal Getaran: 

1. Memanfaatkan fasa untuk analisis, jumlah dan selisih frekuensi, normalisasi kecepatan; baseline spectrum;
2. Standar getaran; evaluasi criteria getaran mesin. konsep analisa data domain frekuensi; frekuensi dasar, harmonik dan fasa, analisis data auto power, power spectrum dan cross power; spectrum; analisis dan ciri sinyal getaran dalam domain frekuensi.

3. Misalignment dan Diagnosisnya

• Apakah Alignment itu ?
• Kenapa perlu diperhatikan ?
• Diagnosis statis
• Diagnosis saat mesin bekerja
• Misalignment vs unbalance

4. Pengukuran Alignment

• Metrologi
• Jam ukur (dial indicator)
• Pengukuran poros berputar
• Perhitungan secara grafis
• Pengukuran obyek stasioner
• Pengukuran jarak mekanis
• Transducer elektronik
• Offset vs runout
• Toleransi alignment

5. Metode Reverse Indicator dan Face and Rim

• Setup
• Prinsip dasar
• Kelebihan dan keterbatasan
• Rumus matematika
• Plotting
• Contoh plotting
• Variasi

6. Faktor pengganggu

• Pengukuran non repeatable
• Pondasi jelek
• Studi kasus mesin diesel
• Poros bengkok
• Distorsi casing
• Bar sag
• Perubahan mekanis
• Thermal growth

WHO SHOULD ATTEND: 

• Rotating equipment engineers
• Operators, vibration analysts and technicians, supervisors and Manager
• Everyone who is responsible for operation, maintenance and reliability of rotating equipment.
