Balancing Application
The Enpac 2500 Balancing application provides a simple, direct method to
balance your rotating machinery in one or two planes. You may use the internal
laser tachometer in the Enpac or an external laser tachometer, optical tachometer,
or strobescope for measuring phase during the balance run.
This chapter describes the balancing procedures and measurements you can take
with the Enpac 2500 coupled with a speed-measuring device such as a strobe light
or laser tachometer.
The Balancing application is an add-on program to the Enpac 2500 and must be
installed with the Balancing PCMCIA card from Rockwell Automation.
Refer to Adding Applications to the Enpac 2500 Data Collector on page 59
for
installation instruction.
Overview of Balancing
Measurements
Balancing is the technique for determining the amount and location of the heavy
spot on a rotating shaft so that you can balance it with an equal amount of weight
in the opposite direction. These methods go through the technique, with
stopping points where you start and stop the machine to perform weight addition
or subtraction.
There are three types of measurements in the balancing process:
•
The initial vibration measurement is taken without any added weights on
the machine. The initial vibration measurement establishes a reference of
how the machine vibrates at each plane without any extra weight added.
This vibration is what will be corrected by the correction weight.
