Weekly Intake: A Water Intake Systems Blog

What is a traveling water screen top-side assessment?

By Michael Stock


Cars and HVAC systems aren't the only things that should be regularly inspected by the professionals to make sure they are in proper working order and don't need any parts replaced. Traveling water screens do as well. That's where top-side assessments come in.

Top-side assessments are meant to review the overall performance of a traveling water screen and identify areas that need maintenance before they become a major problem or cause a screen failure.


What is included in a top-side assessment?

During a top-side assessment a factory-trained maintenance technician will:

  • Level the head shaft so it is not causing uneven wear to other parts of the intake system.

  • Inspect basket mesh and frame for damage.

  • Determine if any of the carrier chain joints, bearings, sprockets or tooth inserts are worn and need to be replaced.

  • Check the spray nozzle pattern and spray pressure.

  • Adjust carrier chains to proper tension to prevent them from dragging through the boot and cutting the boot plate.

  • Lubricate the chain and drive coupling.

The results of the assessment are written up so the customer can have them on record. Often times the technician will include recommendations of additional maintenance that can be done or adjustments that can be made to the intake system to improve its performance.


Why are top-side assessments beneficial?

Not only can regularly scheduled top-side assessments prevent catastrophic screen failure and system down time; they can also help extend the life of your current equipment and save you money on maintenance in the long term.
