After the machine had not operated for a week, vibration level Vibration monitored by proximity probes at each bearing. Wide frequency response typically 1 hz up to 10 khz. The system can measure both static (position) and dynamic (vibration) data. Vibration Probe Gap Voltage. The present study elaborates the usage of NSMS system for monitoring LP Turbine and Fan blade vibration in a developmental aero engine program. Impact: The findings led to MSI recommending the inspection of the turbine grounding system. However, it can be difficult to determine the right inspection or remedial plans based on vibration data alone. From Figure 7, the steam end horizontal displacement probes normal vibration level #2. 11.1 shows a common type of blade vibration probe used for the last stage of an LP section. The measurements are taken for various power outputs, ranging from low to high to calculate the change in vibration in response to the change in power. Vibration diagnostics is one of the most important areas of machine condition monitoring and forecasting for such units [1-3], but it is hampered by a high level of high-speed gas turbine engines random vibration created by the combustion process, as well as by the flow of air and combustion products, masking the vibration of many components that determine The continuous monitoring system for a medium or large steam turbine generator is called a Turbine Supervisory Instrumentation System (TSI System). The typical damage caused during gap voltage adjustment is to the tip of the proximity probe; it usually gets smashed. Insert the probe in to the TK-3 probe holder adjust the probe in To verify that the turbine designed in such a way works properly, the series of vibration measurement tests is essential.

Gas turbines run at high speed; aero-derivatives run at speeds that range from 9,000 to 20,000 RPM, while heavy industrials operate at speeds in the 3,000 to 12,000 RPM range. In this paper some of the most effective concepts and techniques related to gas turbine vibration analysis are discussed. The shaft bending will usually cause increased vibration levels (Figure 1). Used in gas turbines, axial compressors, small and mid-size pumps. Two proximity probes were mounted in the north and west directions on the generator and turbine. The user can then compare a vibration monitors reading to the known mechanical vibration signal input viewed by the proximity probe. These transducers are reliable and accurate but are more complex to install correctly than other vibration instrumentation. Vibration Diagnostics 1) Bode Plot. This portable vibration analysis and engine trim balance system for commercial and military aviation is designed to swiftly pinpoint engine problems and eliminate avoidable engine removals. When thrust monitor will show zero value, it means the probe is properly gapped, fix the probe by tightening the lock nut. The velocity probe was one of the first vibration transducers to be built. all these measurement types. Eddy Current Probe.

Once I got involved in a statistical correlation of vibration transducers for each turbine on part (slightly less than 100) of a large fleet of turbines. Basically it is relative vibration measurement. This is common in large critical machines like steam turbines, compressors, and motors that use sleeve-type bearings. The voltage is sent from the power supply through the oscillator demodulator to the probe tip. So voltage difference of 2 to 10 and 10 to 18 is 8 volt. Benefits. Some typical situations arise in Gas Turbines which might also need shaft relative vibration measurements using proximity probes. The values listed in the table were used in ODS software to animate a stick figure drawing of the high- and low-pressure turbine shafts and the generator shaft. Adjust the probe at 10.0 volts. A TSI System includes the typical radial displacement vibration and axial position measurements associated with high speed rotating machinery but also includes measurements that are unique to the long and heavy These transducers are reliable and accurate but are more complex to install correctly than other vibration instrumentation. Strain gauge data allows the vibration of the single blade to be fully characterised, while the tip timing data allows the amplitudes or velocities of vibration 1. For Hydro Turbines, we recommend Vibration Meters with the ability to measure Vibration Amplitude in terms of Velocity and Displacement. VIBRATION PROBE. However, such a process is quite complex due to high turbine rotational speed, high temperature of exhaust gases driving the turbine and often Equipment setup and results. ODS testing indicated a minor soft foot phenomenon, but its impact on the rotor vibration issue in question was not related. The following photograph shows two displacement probes sensing vibration in the The vibration in a Francis turbine of discharge of 23m 3 /s, 143 m net head, and 27.5 MW power output is measured.
