Screw Washer Routine Maintenance

Once per shift:

All applicable components should be lubricated according to the lubrication requirements

Proper lubrication of the bearings and of the seals of submerged rear bearings is the key to long bearing life. Take care not to overgrease the electric motor bearings, however, as overgreasing can block the weep hole designed for water drainage.

Be sure to follow the specific instructions in the manual for how much grease to add and how often.

Reducers, bearings and motors should be inspected for excessive heat once per shift; none of these components should be hot to the touch. Electrical cables, water lines and all connections should be inspected for wear or damage.

Finally, belts should be inspected for proper tension and alignment. Check to see the belt is not worn or damaged; if so, it should be replaced.

Once Per Week

bearing housing bolts and motor bolts should be inspected for tightness. The area around the motor fans should be inspected for cleanliness, and the seals should be inspected for proper performance.

Once Every Three Months

All bolts and fasteners should be inspected for tightness, and all wear shoes and/or paddles should be inspected for wear or damage and replaced if necessary.

You should always keep a stock of wear shoes so you can perform a quick replacement if and when needed.
