Pengertian Vibration Analysis

Vibration Analysis

      Vibration Analysis ( Alat analisa Getaran ) adalah alat ini mempunyai kemampuan untuk mengukur amplitude dan frekuensi getaran yang akan dianalisa. Karena biasanya sebuah mesin mempunyai lebih dari satu frekuensi getaran yang ditimbulkan, frekuensi getaran yang timbul tersebut akan sesuai dengan kerusakan yang tedadi pada mesin tersebut. Alat ini biasanya dilengkapi dengan meter untuk membaca amplitudo getaran yang biasanya juga menyediakan beberapa pilihan skala. Alat ini juga memberikan informasi mengenai data spektrum dari getaran yang terjadi, yaitu data amplitudo terhadap frekuensinya, data ini sangat berguna untuk analisa kerusakan suatu mesin.

Keuntungan Getaran Analisis :

• Menyimpan Perbaikan dan Biaya Produksi
• Mudah Perbaikan Jadwal Pemeliharaan
• Secara drastis Mengurangi Downtime Produksi / Biaya
• Perbaikan berkurang Skala Besar dan FailuresReduces Biaya Pemeliharaan 

      Vibration Analysis pada dasarnya adalah detak jantung dari semua peralatan mekanik. Menangkap Vibrasi ini dalam sejumlah bentuk yang berbeda memungkinkan seorang Vibration Analysis yang berpengalaman untuk mendiagnosa penyakit peralatan, seperti bantalan dipakai, ketidakseimbangan, ketidakselarasan dengan mengukur amplitudo dan frekuensi Vibrasi. Dengan pengetahuan ini, pelanggan dapat mencegah masalah peralatan baik sebelum mereka mempengaruhi produksi.

       Vibration Analysis selalu memberikan informasi berharga untuk melindungi peralatan pelanggan kami dari kegagalan. Deteksi dini masalah memungkinkan pelanggan untuk secara proaktif menyelesaikan masalah pemeliharaan.

Vibrasi Turbin

Pengetahuan Seputar Vibrasi Berlebih Pada Turbin

Vibrasi Turbin dipengaruhi beberapa komponen-komponen pendukung sehingga dapat menghasilkan suatu energi yang dapat dipergunakan untuk membangkitkan peralatan yang memerlukan energi listrik. Proses energi yang dilakukan adalah vibrasi turbin. Vibrasi Turbin Melakukan proses penghasil energi dengan air, dialirkan melalui pipa pesat, energi potensial diubah menjadi energi kinetik dimana sejumlah energi akan hilang karena gesekan yang merubah energi gerak menjadi energi panas. Turbin bermacam-macam bentuk dan prosesnya, ada turbin uap, turbin angin, turbin air, dll.

Berikut berbagai macam yang meliputi turbin air ada porpeller turbine, francis turbine, kaplan turbine, pelton turbine. Turbin merupakan alat yang beroperasi dalam proses penghasil energi panas untuk menghasilkan energi yang berbeda. Pada setiap mesin pasti ada sebuah getaran yang sangat diperhatikan adalah torsional vibration. Torsional Vibration merupakan proses dimana bagian pusat badan turbin yang diputar pada saat terjadi proses perputaran, terjadi pula gaya lintang tertentu yang arahnya sama dengan rotasi poros. Proses ini cenderung menciptakan pembengkokan pada poros.

Getaran pada turbin pun terjadi pada getaran sudu (mangkok turbin), bila proses turbin pada sebuah rakitan sudu terkena oleh gaya sesaat akan terjadi getaran, getaran-getaran ini biasa disebut dengan getaran bebas. Getaran-getaran ini merupakan proses yang terjadi pada turbin sehingga kelangsungan turbin dan komponen-komponen turbin lainnya harus saling mendukung dalam proses kinerja. Karena jika salah satu komponen yang berperan pada turbin mengalami pengikisan atau permasalahan akan menyebabkan penghasilan energi kurang maksimal.

Penyebab umum terjadinya getaran:

• Pemilihan bahan dan material yang tidak memenuhi standarisasi yang digunakan untuk turbin atau komponen-komponennya.
• Cara pemasangan atau penempatan turbin tersebut belum tepat sempurna.
• Penyeimbangan yang tidak sesuai.
• Adanya gaya-gaya yang mengganggu kinerja turbin.
• Perbedaan ukuran-ukuran laluan sudu (terjadi akibat ketidaktelitian saat perakitan atau pembuatan).
• Adanya benda-benda asing yang turut serta dalam aliran fluida, yang dapat mengakibatkan ketidakseimbangan pada kinerja turbin, perputaran turbin, dll.

Semua permasalahan dengan kinerja turbin yang disebabkan oleh getaran getaran yang memungkinkan terjadi dapat menimbulkan penurunan kinerja turbin dan kerusakan fisik yang terlihat kasat mata, berikut faktor-faktor yang dapat terjadi:

• Kerusakan pada komponen-komponen turbin berupa:
  
  1. kropos pada komponen komponen turbin.
  2. perubahan bentuk permukaan komponen turbin.
  3. perubahan bentuk komponen-komponen turbin ,dll
• Terjadinya polusi suara atau bunyi di daerah sekitar kompinen turbin.
• Penurunan kecepatan rotasi turbin.
• Penurunan drastis pada efisiensi turbin.
• Penurunan kecepatan putaran torsional poros generator.
• Penuruan daya hasil produksi, dll.

Kinerja turbin merupakan proses yang harus sangat diperhatikan. Oleh karena itu, condition monitoring dapat berperan sebagai pendukung dalam memantau serta merawat komponen-komponen pada turbin. Condition Monitoring umunya digunakan secara berkala sesuai standarisasi dan kebutuhan pada turbin bertujuan untuk meminimalisir dampak-dampak negatif yang memungkinkan penurunan kinerja pada turbin.

Vibration Analysis

 

 Any effective predictive management system has a vibration analyzer at its core.Regular route collection allows you to trend vibration data on your various assets. Vibration analysis and trending allows a plant to foresee future failures, pinpoint the possible causes of those failures and see when a machine is misaligned or out of balance, as well as other conditions that reduce bearing life. As the first component to any great management system, vibrational analysis drives the long-term success of plants around the world.
Like all of our other products, our vibration analyzer works off the iPad platform. The vibration analysis equipment comes with an iPad Air or 2nd generation mini, a custom iPad case to protect against harsh environments, a dual-channel DAQ box for tachometer and accelerometer input, and one accelerometer with a magnetic base and coiled cord.
GTI Predictive Technology also provides its cutting-edge VibePro 7 vibration analysis software with every analyzer. This software is the key to making vibration testing possible on your iPad. It offers a single vibration measurement mode, a route and trending mode and fluid integration with the web application.

Single Measurement Mode

To monitor and capture vibration data on a single machine, our customers utilize the VibePro 7 single measurement mode. In some applications, these single measurements are the only necessary readings. The single measurement mode works with either imperial or metric readings and provides two spectrums in one report. It includes 1.2 million CPM readings and a report manager for organizing and accessing saved reports.

Route and Trending Mode

The route and trending mode utilizes all of the modern features included in our vibration monitoring equipment. Whether you need a full-featured route creation tool or a simple method for route data collection and trending, our vibration analyzer equipment can handle it. Our customers enjoy the freedom to divide their routes into different plants, areas, machines and measuring points.
To further enhance trending, each measurement point offers velocity or acceleration, Fmax range, bearing fault frequencies in CPM, RPM markers, danger and alert thresholds and a temperature threshold. For ease of use, each measurement point can be matched with an image.
You can collect your data by simply touching a measuring point and watching as it loads the spectrum. After collecting the data, you can easily save the data to your route for post-processing and trending. A recording of the spectrum is saved every time you save route data so that you can work with it in the future.
The route and trending mode offers trending in an array of different ways. The main application presents a trend chart for each measurement point. To access additional trending and post-processing options, you can utilize our iPhone, Mac, Windows or Web app. The machine maintenance record feature shows when a machine needs to be further tested. You can simply touch a potentially problematic measurement point and flag the machine as imbalanced, misaligned or experiencing bearing fault. The vibration testing equipment works with your software to organize these issues and remind you about potential problems when needed.
Upgrades are available to our system that can correct imbalance or alignment issues at the touch of a finger. Check with GTI Predictive Technology before investing in any new vibration analysis equipment.
The iPad Vibration Analyzer is now wireless with the new dual channel wireless accelerometer exclusively from GTI Predictive Technology.
