Unbalance is the most common source of machine faults in rotating masses (i.e. fans, pumps, motors, chippers and stranders). Field balancing is the most economical method to correct unbalance in a completely assembled machine. Occasionally, rotating equipment goes out of balance. Either through wear, stress relieving or loss of original balance weights, the vibration will increase.
Vibration Analysis is available to rebalance equipment in the field. Machines that have excess to the rotating assembly can often be balanced with a little or no disassembly. Accurate alignment is essential towards prolonging the life of a machine. Misalignment overloads bearings, causes excessive vibration and is hard on machines.
The
advantages of field balancing are:
a) life expectancy of a machine is maintained
b) disassembly and transport of rotors is not required
c) mountings and operating aspects are taken into account once on
site.
Mikan Services Ltd. uses CSI 2120 two channel analyzer/ balancing instruments to balance all types of rotating equipment. Machine history can be referred to and from our database for a complete vibration analysis before balancing. Four accelerometers are used to record vibration amplitude at both arbor bearings (horizontally and vertically), and a phototac provides phase information. Weight correction (amount and location) are calculated from the internal FAST-BAL II program. Trial weights are replaced with welded weights and a final vibration analysis is done to insure precise balance.
