Fitting Instructions for Resilient Mounting of GenSets

Adjustment of Conical elements after 48 Hours Settling

After the conical elements have been deflected under static load for 48 hours the lader height(H1),see fig 2, should be measured and compared to the recommended laden height.

9)Check the laden height by measuring the height of the individual conical element with a gauge block micrometer at two positions.

The difference between the individual conical elements should be as little as possible and not exceed ± 2 mm in order to secure the overall level and load distribution.

Example:

Measuring of Steel Shim

10)Measure the steel shim on several points to obtain the highest possible accuracy during preparation.

Fabricating Steel Shim

11)Make sure that the minimum height of the steel shim is 10mm in order to secure a future replacement of the conical mounting.

Drill the mounting holes in the steel shim according to the conical base casting dimensions.

Mounting of Complete Steel Shim

12)Lift the generating set 1mm totally by means of three jacking bolts.

13)Position each complete steel shim.

14)Re-lower the generating set by means of the three jacking bolts until it rests completely in itself.

Adjustment of Internal buffer

15)Turn the internal buffer clockwise until it makes contact with the supporting steel shim.

16)Turn the internal buffer anti-clockwise until it makes contact with the base casting.

This must be done in four full turns.

17)Turn the internal buffer 1½ turn clockwise and check with a feeler gauge between the bottom flange on the conical element and the supporting steel shim that the internal buffer (2), see fig 1, does not touch the supporting steel shim.

18)Mount the nut (1). Then block the internal buffer (2) with a spanner and at the same time tighten the nut (1) according to page 500.40.

Mounting of Conical Elements to Foundation

19)Remove the dowel pins.

20)Drill four mounting holes in the foundation for each conical element.

21)Fix the conical element and the supporting steel /shim to the foundation with four bolts.

22)Weld the lowest steel shim to the foundation.

Note: After completion of the above, the buffer clearance must be checked, see items 15,16,17 and 18.

Adjustment of Conical elements after 48 Hours Settling

After the conical elements have been deflected under static load, for 48 hours, the laden height(H1),see fig 2, should be measured and compared to the recommended laden height.

9)Check the laden height by measuring the height of the individual conical element with a gauge block micrometer at two positions.

The difference between the individual conical elements should be as little as possible and not exceed ± 2 mm in order to secure the overall level and load distribution.

Example:

Measuring of Steel Shim and chockfast

10) The steel shim should be at least 10 mm high.

Check the minimum permitted thickness of chockfast for the load and surface of this application with chockfast supplier.

Fabricating Steel Shim

Make sure that the minimum height of the steel shim is 10mm in order to secure a future replacement of the conical mounting.

11)Drill the mounting holes in the steel shim according to the mounting holes in the supporting steel shim.

Adjustment of Internal buffer

12)Turn the internal buffer clockwise until it makes contact with the supporting steel shim.

13)Turn the internal buffer anti-clockwise until it makes contact with the base casting.

This must be done in four full turns.

14)Turn the internal buffer 1½ turn clockwise and check with a feeler gauge between the bottom flange on the conical element and the supporting steel shim that the internal buffer (2), see fig 1, does not touch the supporting steel shim.

15)Mount the nut (1). Then block the internal buffer (2) with a spanner and at the same time tighten the nut (1) according to page 500.40.

Mounting of Conical Elements to Foundation

16)Drill mounting holes in the foundation according to the supporting steel shim/steel shim and chockfast.

Make sure that the mounting bolts are isolated from the chockfast.

Note: After completion of the above, the buffer clearance must be checked, see items 12,13,14 and 15.
