  • Page 17: How To Interpret Vibration Levels

    This measure gives a good understanding of the amount of “break down energy”, causing mainly wear and fatigue in the machine or the structure. The instrument measures the total RMS vibration value in the frequency range. This RMS value is the average sum of all the measured vibrations. Example: If the simultaneous vibration caused by unbalance is (4mm/s), by misalign- ment (2 mm/s) and by the gear mesh (5 mm/s) then the total vibration mea- sured with VIBER X3™ is 6.7 mm/s. √ Total vibration(RMS)= 4*4+2*2+5*5=6,7mm/s Notice that a reduction of the unbalance from 4 mm/s to 1 mm/s will reduce the total value from 6, 7 mm/s to 5, 5 mm/s.
  • Page 18 Vibra on Measurement Instruments 8.1 ISO standard 10816-3 The ISO standard 10816-3 classifies machines differently whether the machi- nes are considered as flexible or rigid mounted. This reflects the location of the machines stiff-body resonances related to the basic running speed of the machine. For instance, a machine supported by rubber or spring, have resonances at low running speeds. The machine starts vibrate at certain low revolutions. When the speed is increased above these resonance frequencies, the vibra- 3.1 ISO standard 10816-3 tion is reduced. This machine is considered flexible.

  • Page 19: Vibration Analysis

    Vibra on Measurement Instruments 9 Vibration analysis Recommended vibration levels in mm/s and common findings The list and table on previous page can be used, as a first consideration, when you approach a machine newly commissioned or after some time in operation. Investigate the reason for any machine that vibrates above 3 mm/s RMS. Do not leave levels above 7 mm/s without analyzing consequences. 0 – 3 mm/s | 0 – 0,12 in/s Small vibrations - None or very small bearing wear. Rather low noise level.
  • Page 20 Vibra on Measurement Instruments 9.1 Resonance A resonance can easily be found when a flexible machine is running up or down its speed. The resonance frequencies are located at the RPM’s, where the vibration has a local maximum level. To understand a resonance you can compare with the string of a guitar. The string has its natural basic tone that will ring as soon as the string is struck. The actual frequency of the tune depends on the stiffness and the distributed mass of the string.

  • Page 22 9.3 Listening to bearing sound The listening of bearing sound is an old method. Sound analyzes of low speed bearings and gears can sometimes be much faster and even more reli- able than just BC-value. With the VIBER X3™ you can both listen and look at the BC value and vibration at the same time.

  • Page 23: Balancing With Viber X3

    10 Balancing with VIBER X3™ This chapter describes how you can perform balancing with your instrument The 3-Point Balancing method does not need any additional hardware exept for the VIBER X3™ instrument and the accelerometer. Mount the acce- lerometer on the bearing and in the direction where you have the highest vibration caused by unbalance. Use this measuring point for all following measurements.
  • Page 24 • Balancing using this method requires only three consecutive trial runs and changing the balance status of the rotor. • Only measurement of the vibration level is needed. • Balancing will only reduce the vibration caused by unbalance. • VIBER X3™ can display the frequency of the 5 highest peaks, unless one of them is the same as actual speed the cause of high vibration probably is something else. • A balancing round will often be a good approach and a first attempt to find the reason for increased vibration. If the balancing attempt is not successful, the cause can be loose rotor parts or other faults.

    Trends are one method to perform condition monitoring (CM). TREND VIEW ™ is designed for use only with VIBER X3™. For every plant or building, you can create a database and a route with up to 100 measurements. Each measurement store vibration amplitude and bearing condition.
