Dismantling; Fan Disposal - Ferrari IS3.006 Betriebsanleitung

15. Checking the alignment of the fan shaft-motor flexible joint coupling (only for fans types 8): this inspection
permits the prevention of misalignment between the shafts causing damage to the bearings of both the fan
and the motor and creating hazardous situations. After alignment inspection, always remember to fit the
protection guard back on in accordance with the provisions in the typical section attached to fan
documentation. (To be checked during commissioning, every 600 hours of operation and at the end
of each maintenance job performed on the fan and/or motor)
16. Checking the condition of the lubricant: this inspection ensures correct lubrication of the bearings and
prevents these being damaged, with risk of hazardous situations and damage to the fan. The transmission
cards supplied with the documentation attached to the fan indicate lubrication schedules. These indications
have priority over all general indications. Refer to the operator's instruction Manual MVC 02/17 or MVA
02/17, or later, for lubrication schedule details. (To be checked during commissioning and every 600
hours of operation unless otherwise indicated)
17. Checking the condition of the bearings: this inspection protects bearing life and prevents any early damage
to the bearings. To make this inspection, totally eliminate the grease from the supports. For the types of
bearings used, refer to the operator's instruction Manual MVC 02/17 or MVA 02/17, or later. (To be
checked every 2000 hours of operation).
In order to make some of these inspections easier, the best thing is to equip the fan with permanent measuring
systems for vibrations, temperature of bearings or other parts subject to vibrations/overheating, as well as with
speed sensors. Ferrari remains at disposal to evaluate the fitting of such accessory devices. Moreover, different
inspections involving the same component (e.g., bearings, points 1 and 2) should be performed at set intervals but
at different times. This way it will be possible to identify any operating faults quicker. With the aim of making the
inspections indicated from point 1 to point 17 easier, we attach a specimen page of how the data obtained from
systematic parameter checks should be recorded. See Table 2 on page 11 - Inspections during commissioning and
at page 12 Table 3 – Inspections to be made at regular intervals.
