Analysis and Comments

While the body of the transfomer is no more than 35'C at any point, the top of the connection box is showing a high temperature at over 57'C. The most probable casue for this high temperature is a resistance connection inside the connection box.

Recommendations Check the connection box internals as a matter of urgency and remake all electrical connections therein.

The left most fuse on the upper bank is considerably warmer than all others.

Recommendations The circuit should be checked for load. Then replace the fuse, clean the fuse clips and check terminations for security.

The input shaft on this gearbox is hot at over 80'C. This is most likely indicative of a bad bearing or possibly bad gears.

Recommendations The gearbox should be overhauled.

Even though the discharge screw was lightly loaded at the time of measurement, the input shaft bearings were over 40'C. This is indicative of overloaded bearings or low oil level.

Recommendations Check the gearbox oil level. If oil level is OK then overhaul the gearbox. On reassembly pay particular attention to the mounting arrangement for the motor to avoid misalignment.

The pump drive motor drive end bearing is relatively hot at over 50'C. This could be caused by over greasing, misalignment or bearing deterioration.

Recommendations Monitor the bearing temperature in the short term. Arrange to change the motor bearings and carry out an alignment of the motor to the pump.
