Mechanical faults

The following table shows the possible causes of and remedial measures for mechanical

faults.

Table 8-2

Mechanical faults

↓ Grinding noise

↓ Overheating

↓ Radial vibrations

↓ Axial vibrations

Possible causes of faults

Remedial measures

Rotating parts are grinding

Establish the cause and realign the parts.

Reduced air supply, direction of rotation of fan pos‐

sibly incorrect

Check the air ducts; clean the machine.

Rotor not balanced

Decouple the rotor and then rebalance it.

Rotor out of true, shaft bent

Please consult the manufacturer.

X Poor alignment

Align the machine set and check the coupling

①

Coupled machine not balanced

Rebalance the coupled machine.

X Shocks from coupled machine

Investigate the coupled machine.

X Fault originating from gearing

Fix the gearing.

X Resonance of the overall system comprising motor

and foundation

Reinforce the foundation after consultation with the

manufacturer.

X Changes in foundation

Determine the cause and rectify it. Realign the ma‐

chine.
