SUMMARY

AND CONCLUSIONS A vibration baseline survey was carried out Nov. 13 1986 to ,

identify the vibration characteristics of the emergency diesel i

' generator 'A' at the Rancho Seco Nuclear Power Station. The diesel engine involved was an in-line 8-cylinder engine (DSR-48) manufactured by Transamerica DeLaval.

Sixty-eight measurements were taken at thirty-five locations on l

the engine and its auxiliary equipment. The vibration survey was carried out in accordance with a document issued by the TDI Owners Group and entitled: " Test Procedure for Engine Baseline-Vibration Survey for DSR-48 Engines".

The field measurements were analyzed in the 0-100 Hz range and are presented here in the form of tables of vibration amplitudes and plots of vibration spectra. The measured overall vibration amplitudes, with the exception of the t'urbo-charger were well below 1.0 in/see pk. A vibration level of 1.0 in/sec pk. is generally considered the upper limit of acceptable vibration for large diesel engines. Up to 4.92 in/sec pk. was measured on the turbo-charger. That level is somewhat higher-than the vibration level observed on the turbo-charger of a similar engine at the River Bend Nuclear Power Station before ,

modifications to the turbine exhaust arrangement.

The average vibration level, calculated from 55 measurements (excluding the turbo-charger locations) was 0.2 in/sec ph. That level is lower than the corresponding values measured on two similar engines surveyed in other plants.

2.2 CALIBRATION The velocity probes and the reference accelerometer were l calibrated against a precision accelerometer in the Acoustics and Vibration Laboratory of Stone & Webster Engineering Corporation. A shaker table, ' swept-sine' excitation and transfer function techniques were used. The calibration is traceable to NBS.

The calibration of the velocity probes was verified in the field both before and after each baseline survey in the following manner. The probes were mounted on a fixture back to back with an accelerometer (one velocity probe at a time). The fixture was then attached to the engine under operating conditions. Using transfer function measurements on the two vibration signals the calibration of each velocity transducer and the associated signal conditioning equipment was verified in t.erms of the known output of the reference accelerometer.

The correct functioning of the reference accelerometer was verified in the field by employing a ' free-fall' technique that provided a momentary 1.0 g input to the system. The overall accuracy of the subsequently performed vibration measurements is estimated to be +/- 10 per cent.

3.0 MEASUREMENT AND ANALYSIS PROCEDURE The survey was carried out in accordance with a document issued by the TDI Owners Group and entitled: " Test Procedure for Engine Baseline Vibration Survey for DSR-48 Engines". Vibration measurements were made at 35 points on the engine with the engine operated at 3500 kW, 500 kVAR synchronous load. The measurement locations are identified in Figures 2 and 2A. A brief description of each measurement location is given in Table 2.

At each location measurements were made in as many of the axial (A), horizontal (H) and vertical (V) directions as permitted by local geometry. The measurement axes were mutually perpendicular and the axial direction was paral 3 e1 to the axis of the crankshaft.

All measurements were taken using two velocity transducers.

One reference transducer was mounted on the generator outboard bearing (location No. 1), and kept there for the duration of the test. Its function was to verify that the operating conditions remained the same throughout the test. The second velocity probe served as a roving transducer at the measurement locations.

The output from both transducers was recorded on magnetic tape in analog form for later analysis.

The magnetic recordings were subsequently processed in the laboratory with a dual channel Fast Fourier Transform (FFT) analyzer to obtain velocity and displacement amplitudes in terms of in/see pk. and mils p p respectively. Plots of vibration amplitudes vs. frequency were prepared in the frequency range of 0-100 Hz and the spectral amplitudes corresponding to 18 engine half orders were printed out. The processed data presented in the Appendix were stored in digital form for future reference.

4.0 SURVEY RHSULTS The vibration spectra plotted in terms of both velocity and displacement are presented in Figures 3 through 70. The frequency range covered is 0-100 Hz. The amplitudes are plotted to a linear scale. The vibration amplitudes of 18 engine half orders and the overall vibration levels have also been printed in Figures 3 through 70. Tables 3 through 5 summarize the overall vibration levels observed at the various measurement locations on the engine. Table 3 is organized according to measurement location while the entries in Tables 4 and 5 are sorted in desconding order of velocity and displacement amplitudes respectively.

The highest vibration level was measured on the turbo-charger at location 11. The measured 4.92 in/sec pk. vibration is excessive and represents a rocking motion of the scroll case. The motion 6

5.0 CONCLUSION

S AND RECOMMENDATIONS

A careful' review of the data indicates that the measurements are accurate and consistent.

In general the measured vibration spectra contain significant components only at the-expected frequencies corresponding to the engine orders and half orders. The distribution of the frequency content appears to be normal.

The vibration level on the turbo-charger was over 4.9 in/see pk. and must be considered excessive. Similar vibration levels were observed on other DSR-48 engines before corrective modifications.

The average overall vibration level on engine 'A' was 0.2 in/see pk. which is about 20 per cent lower than the corresponding vibration level measured on two other DSR-48 engines previously surveyed.
