US Patent:

48528501, Aug 1, 1989

Filed:

May 14, 1987

Appl. No.:

7/049364

Inventors:

Peter L. Wilhelm - Winter Springs FL
Gilbert F. Hyde - Winter Springs FL

Assignee:

Westinghouse Electric Corp. - Pittsburgh PA

International Classification:

F16K 31122

US Classification:

251 28

Abstract:

A steam bypass valve system for a steam turbine. The system provides a supplemental hydraulic seating force to a fast acting bypass valve after the valve plug is positioned against the valve seat with a spring force. The system also provides for quick hydraulic relief in order to retain the fast opening characteristics of a single acting hydraulic valve.

US Patent:

48703931, Sep 26, 1989

Filed:

Apr 8, 1988

Appl. No.:

7/179098

Inventors:

Owen R. Snuttjer - Oviedo FL
Peter L. Wilhelm - Winter Springs FL

Assignee:

Westinghouse Electric Corp. - Pittsburgh PA

International Classification:

G08B 2100

US Classification:

340611

Abstract:

The ratio of the pressure change across a portion of the ventilation system of a hydrogen cooled electric power generator to the pressure increase across a reference blower, preferably the purity blower, is compared to a base ratio to generate an alarm when the difference in ratios exceeds a predetermined amount indicative of a failure within the ventilation system.

Filed:

Oct 2, 1991

Appl. No.:

7/770192

Inventors:

Peter L. Wilhelm - Winter Springs FL
Robert F. Gray - Winter Springs FL
Maurice A. Jenkins - Casselberry FL

Assignee:

Westinghouse Electric Corp. - Pittsburgh PA

International Classification:

G06F 1520

US Classification:

364510

Abstract:

An electrohydraulic fluid system monitors the fluid line 1, reservoir 2, motor pumps 4 and 6, accumulators 10 and drain line 13 in an electrohydraulic fluid system. The electrohydraulic fluid monitor system includes sensors 14-40 to detect temperature, pressure, fluid level and motor pump current in the electrohydraulic fluid system. Signals from these sensors are converted 54 by an analog to digital converter into digital signals read by a processor unit 58 and stored by the processor unit as data for diagnostic analysis. In one embodiment of the present invention, the processor unit 58 stores the information and compares the information to predetermined threshold amounts or to previous values and outputs a malfunction indication to a status display, responsive to results of these comparisons, which indicates the presence or nonpresence of a malfunction in the electrohydraulic fluid system. In another embodiment of the present invention, the microprocessor outputs the information to an artificial intelligence system 94. The artificial intelligence system 94 applies a set of diagnostic rules from a rule storage 96 to obtain a malfunction diagnosis or hypothesis that indicates other rules to be applied to diagnose the malfunction.

International Classification:

US Classification:

148519

Abstract:

An austenitic rounding fixture is inserted into the horizontal joint of a turbine casing. The casing is then assembled and stress relief cycle is carried out, resulting in rerounding of the casing and relief of residual stresses. Since an austenitic material has a higher thermal expansion coefficient than the metallic materials of conventional turbine casings, the rounding fixtures expand more than the casing during a stress relief cycle. The length of the fixtures are designed in such a way that at stress relief temperature the casing is slightly over-rounded. After the stress relief, the casing is rerounded and the austenitic rounding Fixtures is disengaged. The rounding fixture is installed in a cold condition (or with minimal heat for heavily collapsed casings). The removal of the rounding fixtures is easy since a clearance exists between the casing and the fixtures; the spring back of the casing is far less then the contraction of the fixtures. The stresses in the casing are far less than if rounding plates would have been used since the maximum deformation occurs at stress relief temperature.
