Anti-Vibration Mounts – Spring (Compression)

AVMs should be installed in accordance with the following procedure:

1. The structure beneath the machine should be constructed to form a rigid and reasonably level seating for each group of AVMs.

2. The AVM should be examined to ensure they are of the correct size.

3. After the AVMs are in position, the machine base should be levelled and supported just clear of the AVM tops using jacks or blocks, ensuring alignment between isolator and machine fixing holes.

At this stage, hold down bolts can be loosely fitted to maintain AVM positions during final lowering of machine base, but it is important these do not strain the AVM in any direction (hold down bolts are supplied by others).

4. After removal of blocks, the machine base can be carefully lowered evenly across supported area transferring full weight to the AVMs.

Adjusting screws should then be located through machine base into AVM tops, ensuring sufficient length for adjustment.

5. Tighten the adjustment screw after initial deflection to raise the upper spring cover until desired height of AVM is achieved or the machine is level, see Figure 1.

DO NOT adjust by more than the original deflection obtained when the load was applied to the mounting.

IF NO adjustment is required, adjusting screw must be wound down sufficiently so that the spring pressure is felt before tightening the locknut

Figure 1.

6. Isolator hold down bolts and top locknuts should now be fully tightened.

7. Ribbed rubber seating pads should always be used when the mounting is seated on concrete or other rough surfaces.

8. Note: AVMs are not designed to accommodate angular misalignment, excessive horizontal or tensile forces and must not be used for tensile or shear loading applications.

9. The efficiency of an AVM system can be seriously impaired if the system is connected to rigid pipes, electrical conduits, ducts or shafts. It is essential that such external connections be as flexible as possible, not only to prevent transmission of vibration through the connections and allow the system freedom of movement, but also to avoid possible failure of the connections.

Anti-Vibration Mounts – Rubber (Compression)

AVMs should be installed in accordance with the following procedure:

1. The structure beneath the machines should be constructed to form a rigid and reasonably level seating for each group of AVMs.

2. The AVMs should be examined to ensure they are of the correct size and rubber compound. If appropriate, the positions for different rubber compounds should be located in accordance with our recommendations or drawings.

3. Either bolt the isolators to the underside of the machine base or position them upon the prepared seating before lowering the machine into position.

4. Jacks or blocks should be used to support the machine in a level state with a small clearance above or below each AVM. The clearances must be measured and if they vary by more than 0.5 mm then steel or other rigid packing pieces should be fitted before transferring the machine weight onto the AVMs. These packing pieces may be fitted above or below the AVMs and should be of adequate size.

5. AVM hold down bolts should now be fitted (if applicable). These must not strain the isolator in any direction. The AVMs are not designed to accommodate angular misalignment, variations in level, excessive horizontal forces or tensile forces. (hold down bolts supplied by others).

6. It is recommended that AVM top fixing bolts material grade 8.8 be tightened to their correct torque values.

7. Note these AVMs are not designed for tensile or shear loading applications, and should only be installed in accordance with our recommendations.

8. The efficiency of an AVM system can be seriously impaired if the system is connected to rigid pipes, electrical conduits, ducts or shafts. It is essential that such external connections be as flexible as possible, not only to prevent transmission of vibration through the connections and allow the system freedom of movement, but also to avoid possible failure of the connections.

Adjoining Ductwork & Attenuators

Adjoining duct work and attenuation should be adequately supported to prevent undue stresses on the fan casing / structure.

1. By fitting a correctly designed inlet cone the air flow to the impeller will be uniform resulting in the performance being optimised and minimum noise level generated.

2. Square-to-round transitions and turning vanes in elbows assist uniform airflow; this is a compromise only and is by no means ideal.

3. With a correctly designed discharge diffuser the pressure recovery in the diffuser will reduce the system total pressure. Included angle of diffuser to be 15° or less. Discharge losses reduced substantially in this arrangement.

4. Allow a gap of at least one fan diameter between fan outlet and obstruction and fit a diffuser on the discharge.

Elta Fans Limited has a policy of continuous product development and improvement and therefore reserves the right to supply products which may differ from those illustrated and described in this publication. Confirmation of dimensions and data will be supplied on request.

SAFE AREA, SMOKEVENT AND

HAZARDOUS AREA

Allow a gap at least equal to one fan diameter between the fan intake and nearby obstructions; even then fan performance can be less than rated. Always fit an inlet cone on open axial fan inlets.

5. Duct expansion on the inlet to axial flow fans should be avoided where at all possible. If essential the transition should have an included angle of not more than 15°.

6. Ensure open fan inlets are fitted with suitable guards. These should be designed to comply with local regulations and not only protect against injury but lessen the risk of a foreign object entering the fan and causing damage.

For further information of ducting system Do’s and Don’ts please contact Elta Fans Limited for a copy of our “Give a Fan a Chance” brochure.

Start-Up Procedure

1. Ensure that all electrical circuits are complete, tested and acceptable for use.

2. Ensure that the local isolator is turned to the ON position and that there are no obstructions or debris within the fan ducting that could cause damage to the impeller.

3. Initially, switch the unit on briefly in order to confirm that the rotation and airflow direction are as required.

4. Check that the current drawn (FLC) by the fan does not exceed that stated on the fan nameplate.

5. If contact is evident, stop the fan immediately and re-centralise the impeller maintaining equal tip clearances.

6. Once satisfied with the results of the test, the fan should be run for a further 30 minutes to ensure smooth and trouble free operation, should no problems occur, the fan unit may be considered ready for use.

7. Once all units have passed the above stated procedure, a full system test should be conducted in accordance with the control methodology.

8. Upon completion of the above procedure, the ventilation system shall be considered suitable for commissioning.

9. Reverse wind milling of the impeller should be avoided and the use of non-return dampers should be considered in these cases. Refer to Appendices for Fault Finding and Fan Commissioning Record.

General Maintenance (Preventative)

1. Inspection of ventilation equipment should be carried out at regular intervals, not exceeding 6 months.

2. If the equipment forms part of a larger safety system. It is imperative that a site specific program for regular maintenance should be created indicating a scope of work against a specified period of time that complies with the requirement of the site or application.

3. Ensure that the fan has been locally isolated before commencing work on any part of the fan.

4. Ensure that the impeller has come to a complete stand-still before commencing work on the fan / motor assembly.

5. Following electrical isolation of the fan, all electrical connections and interfaces are to be checked and repaired as required, then retested for effectiveness.

6. Ensure that no debris or dirt is attached to the fan assembly that may obstruct the effectiveness of the unit and a suitable method is available for the removal of any debris found inside. Fan accessories such as guards and dampers should be checked and cleaned as required.

7. Sealed for life bearing motors do not require maintenance. However bearing L10 life is typically 25000 to 30000 hours, for details refer to motor manual.
