Device for bearing diagnostics using shock pulse method
Operation manual
Section 4 Operation

To ensure efficient bearing monitoring the following conditions should be met:
Careful preparation for obtaining effective initial values of good bearing
and equipment condition;
Planned and perfect procedure of periodic data collection;
All-around evaluation of any result deviating from the good condition
4.3.2.
Measurement procedure
Application
The measurement range of BALTECH VP-3450 allows measuring bearings with
the maximum rotation frequency up to 19,999 rpm and maximum dBi 40.
The minimum dBi value is -9dBi; the real limit is 0 dBi, as in case of low
values for low-speed bearings it is almost not possible to obtain useful
information on the bearing condition.
Measurement range
Normally, a bearing damage develops very slowly, and a measurement
interval is determined according to the following rules:
• Bearings should be inspected at least once a month;
• Critical equipment and heavily loaded bearings shall be measured more
frequently than standard bearings;
• Bearings should be monitored more frequently if their measuring values
are not stable;
• Damaged bearings should be monitored as frequently as possible.
Note
After bearing lubrication at least one hour should go by before start operating
it.
