4.2 Troubleshooting
Note: Part numbers appearing below may be used to identify parts in the exploded views in Chapter 7.
- WATER LEAKING OUT OF THE BOTTOM CAP
The Alfa Laval BladeClean has a seal (9) on the main body (7) to prevent any water from going down into the bottom cap (10).
If water is seen leaking from the weep holes on the bottom cap, check this seal for any damage. If damaged, replace the seal
with a new one. If not the seal, check the bearings (5) for any damages.
- PLUNGER NOT RECESSING
If the plunger does not operate smoothly, check the wave spring (14) in the bottom cap for any damage. Try running clean
water through the Alfa Laval BladeClean to get rid of any debris causing the trouble. The O-ring on the plunger could also be
getting in the way of the plunger; replace it if needed.
- POOR CLEANING PERFORMANCE
Check the flow and pressure at the Alfa Laval BladeClean inlet under actual operating conditions. Make sure to refer the
pressure-flow table to reconfirm the operating conditions. Insufficient pressure may result from line losses when the machine is
located far from the pump, so the line size must be increased accordingly for long runs.
Verify that the cleaning solution is the correct compound and in the concentration needed for the deposit being cleaned. If
heating is necessary, also check that the solution is at the proper temperature.
Unscrew the Alfa Laval BladeClean and inspect for any debris. Determine if the deposit being cleaned requires greater impact
or longer impact time for more thorough scrubbing. Contact Alfa Laval Tank Equipment Inc. for assistance, if needed.
Ensure that the vessel drains the effluent or used wash fluid at an equal or faster rate being sprayed in through the Alfa Laval
BladeClean. Make sure the water collected is not covering the Alfa Laval BladeClean outlet, thus blocking the spray. The floor
of the vessel should be sloped or pitched toward the drain and the drainage opening should be large enough to gravity-drain
the effluent from the vessel. If you still have puddling, use some form of pump to suck out the effluent.
