Abstract: A method for monitoring turbine blade vibrations comprises the step of transmitting a continuous wave of microwave energy toward a rotating row of blades. Each passage of an individual blade tip through the path of the continuous wave produces a signal indicative of the time at which each passage occurs. The signal is then monitored and analyzed to detect blade vibrations. The signal can be based on a standing wave or a reflected wave.

Abstract: Apparatus for automatically cleaning shaft grounding devices in rotating machinery to reduce or eliminate the need for on-line servicing of the grounding devices. When a monitoring system for the grounding devices signals that an excessive electrical charge is present on the shaft, a cleansing material is sprayed at the interface of the grounding device with the shaft to remove any contaminants for the electrical insulating material between the bearings and the rotating shaft, and to re-establish the grounding path from the shaft. Voltage discharge from the shaft to the bearings through the bearing lubricating oil is thereby prevented. Alarm delay of the shaft ground monitoring device allows the apparatus to function automatically, obviating the need for on-servicing by plant personnel or unnecessary shut down of the machinery.

Abstract: A normally closed valve system for sealing off low pressure gas flow through a pipe. The valve system comprises an inflatable bladder which blocks relatively low pressure flow through the pipe and permits relatively high pressure flow through the pipe. In one form, the invention comprises a fail-safe bypass monitor and method for measuring air inleakage in a steam turbine. The monitor selectably bypasses low volumetric flow rates from a pipe for measurement and admits flow through the pipe whenever the flow rate exceeds a predetermined value.

Abstract: Apparatus for monitoring displacement of a translational member in a pressurized vessel. In one form, the apparatus comprises first and second fluid containing compressible bellows each coupled to a differential pressure gauge in order to measure pressure fluctuations between the bellows. An end portion of the first bellows is coupled to the translational member in order to receive a variable compressive force as the member is displaced. The displacement of the translational member is determined as a function of the pressure variation between the first and second bellows.

Abstract: A non-return valve for a steam turbine steam line includes a housing and a clapper swingably mounted in the housing for angular movement between open and closed positions. A metal proximity detector is mounted on the interior surface of the cover for the valve access opening and adjacent the open position of the valve. Movement of the clapper away from its open position results in a signal providing an indication that the valve clapper is away from its open position.

The system comprises a plurality of controllable fluid jets disposed about a blade row for exciting rotating blades with selectable frequencies of vibration. The sequential excitation of blades at a plurality of narrowly spaced frequencies and the simultaneous sensing of blade responses sufficiently resolves the resonant center frequencies and harmonics thereof in order to detect changes in characteristic blade resonances.
