Periodical Maintenance And Troubleshooting - FPZ SCL K04 MS-GOR Betriebsanleitung

Danger due to seizing of the impeller caused by excessive vibration.
Vibration values higher than Zone B (table of effective vibration velocity value) are considered NOT permissible and can cause damage
to the machine and therefore serious injury to operators.
- In case of noise and/or abnormal vibration indicating the possibility of seizing of the impeller, move away and turn the unit
off immediately!
Variations in normal working conditions (increases in power absorption, abnormal noise, vibration, excessive overheating of the service
fluid) are signs of a unit malfunction.
Also, compare the measured values with those given in the "SPECIFICATIONS.
B) With the unit stopped and cooled, periodically carry out the following checks:
•
Dust: check and remove deposits from the external surfaces of the unit.
•
Suction filter (if fitted): every 10-15 days, check and clean or replace the filter cartridge. The dirty cartridge creates strong
suction resistance and consequently a higher pressure differential, power absorption and operating temperature.
•
Check the flexible coupling as follows:
- Remove the screws and coupling cover (A).
- Manually rotate the coupling to expose the reference lines marked on the elastomer.
- Check the coupling and appraise its state after 100 hours or up to 1 month of operation; if no deformations are detected,
the check can be repeated every 2000 hours or every 3 months.
- The deformations are detected by the lines marked on the elastomer (B).
- Protect the couplings again with the coupling cover (C).

the environment, ensure regular cleaning and removal with suitable equipment.
The suction and/or delivery pipes must not be dirty or clogged.

14.2 PERIODICAL MAINTENANCE AND TROUBLESHOOTING

Refer to the following section, "OPERATION PROBLEMS", to identify possible critical situations and types of failures.
In case of periodical maintenance for cleaning and replacement of some components, as well as in case of failure, it is necessary to
disconnect and remove the machine from the system.
Danger due to electricity.
Before carrying out any operation, make sure the machine is NOT powered.
Risk of injury due to shearing, crushing, catching.
During work on the unit there are risks of injury due to shearing, crushing or catching.
Therefore it must be carried out by qualified personnel who handle and install the machine, taking the necessary safety measures and
following the instructions given in this manual.
Danger due to residual negative pressure or overpressure.
For residual overpressure: possible release of process fluids with risk of injury to the skin and eyes.
For negative pressure: possible drawing in of hair and clothing.
Disassemble the machine only after closing and draining the system connected to it.
