Abstract

Misalignment is one of the problems that often occurs in rotary equipment. In this paper, the observation was done to the rotary machine model in response to changes of axial misalignment by using vibration meter and infrared thermography camera. The model was a machine series, consisting of electric motor and disc which was connected by 3 Jaw flexible coupling. The shafts were positioned into several axial misalignment conditions to see the effect on the overall vibration value and its component temperature. The result of vibration observation showed that under certain conditions, by increasing shaft misalignment then the overall vibration value tends to decrease. With the decrease of overall vibration value, the machine condition was not in better condition. This was indicated by observing the temperature of the components in this condition, which showed the opposite fact. As misalignment increases, the temperature of the engine components also increases.

Abstract

Looseness occurs in almost all machines and can changes the vibration of the machine. In this paper, experiments were conducted by using two sets of rotor model to observe the effects of looseness on vibration values and patterns on the spectrum of unbalance and misalignment conditions. Rotor model 1 was used to simulate unbalance condition by adding mass to the disk, while rotor model 2 was used to simulate misalignment by changing the position of the bearing housings. Looseness condition was achieved by loosening the bearing housing bolts. The result of vibration observations in unbalance machine showed that looseness changed the overall value and peak values of vibration spectrum. While in machine which has shaft misalignment condition, looseness changed the vibration patterns on the spectrum.

Abstract

Resolution of vibration spectrum is one of that affect the accuracy of vibration analysis result. This study was conducted to determine the most effective minimum line of resolution (LOR) for determining the target resolution in separating two close peaks. Several parameter settings like Fmax and LOR are used to measure the spectrum of a model rotor. The results of this study indicate that with 3 LORs in the separating frequency, the spectrum is quite detailed in separating two close peaks. This experimental study resulted a simple calculation in determining the minimum amount of LOR for routine vibration measurements. ABSTRAK Salah satu hal yang berpengaruh terhadap ketepatan analisa data vibrasi adalah resolusi grafik spektrum vibrasi. Penelitian ini dilakukan untuk mengetahui jumlah minimal line of resolution (LOR) yang paling efektif untuk menentukan target resolusi dalam memisahkan dua buah peak yang berdekatan. Beberapa setting parameter seperti Fmax dan LOR digunakan untuk melakukan pengukuran spektrum dari suatu rotor model. Hasil penelitian ini menunjukkan bahwa dengan 3 buah LOR dalam separating frequency, spektrum yang dihasilkan yang cukup detail dalam memisahkan dua buah peak yang berdekatan. Studi eksperimen ini menghasilkan perhitungan sederhana dalam penenentuan jumlah minimal LOR untuk pengukuran rutin vibrasi.
