Mechanical Solutions Case Studies
This case study describes the application of two-plane balancing to a large coal crusher.
Bearing fault in large motor
The following case study was taken from a regular survey of plant located at the site one of our customers.
Slow speed diagnostics
Many industrial machines operate at such slow rotational speeds that vibration generated by common machine malfunctions, such as imbalance, misalignment, and bearing faults, falls below the sensor frequency response range.
Fan bearing failure
A vibration increase was noted in a 3000 rpm fan. On shutdown, one bearing was found to have serious defects.
Motor Bearing failure
An inner race fault was successfully detected in the bearing of a motor for a cooling water pump.
Monitoring the paper machine press section
The fundamental function of a paper machine press section is to remove water from the paper sheet.
Identifying the stages of bearing damage
The early identification of troublesome conditions such as inadequate lubrication or misalignment enables an analyst to apply proactive corrective measures to extend bearing service life. The onset of bearing deterioration often occurs very early on, as raceways begin to wear, developing micropitting in the load zone.
