In one embodiment, a system includes: a first member adapted to connect to a first portion of a turbine shell; a second member adapted to connect to a second portion of the turbine shell; and a measurement device communicatively connecting the first member to the second member for monitoring a displacement value for a joint in the turbine shell between the first portion of the turbine shell and the second portion of the turbine shell.
Description
- The subject matter disclosed herein relates to machines and, more particularly, to systems for monitoring displacements between turbine shell portions during machine maintenance processes.
- Some power plant systems, for example, certain nuclear, simple-cycle and combined-cycle power plant systems, employ turbines in their design and operation. These turbines include a set of shells which partially define a flowpath of the turbine and enclose a plurality of components including turbine buckets, rotors, etc. During maintenance, portions of these shells must be separated (e.g., an upper shell lifted off of a lower shell), so as to allow technicians access to turbine components. The large size of the turbine shells and the tight clearances between turbine components and shell portions may require that the lifting process be synchronized (e.g., portions of the upper shell being lifted in unison relative the lower shell), so as to avoid component contact and damage. In some power generation systems, this lifting may be performed by a team of technicians using tape measures and a plurality of jacks spaced about the turbine shell. The technicians attempt to synchronize the lift, and maintain a level relationship between the upper shell and the lower shell by calling out to one another current measurements and target increments for each jack. Based upon these called out target increments, the technicians use the jacks to lift the upper shell, monitoring progress and shell lift unison via comparison of periodic tape measure readings. However, this manual measurement and lifting process may be imprecise, time consuming and susceptible to human error.

- As indicated herein, aspects of the invention provide for systems and devices adapted to monitor displacements between turbine shell portions during machine maintenance processes, particularly during shell separation processes. These systems include a set of members adapted to connect to an upper shell portion and a lower shell portion of a turbine. These members are communicatively connected to one another via a measuring device which is adapted to monitor (e.g., measure a vertical movement of the members and/or shell portions) a displacement/distance between the members during shell separation processes. Based on the displacement between the members, technicians may monitor/determine a set of displacement values for a joint between the upper shell and the lower shell during separation. Disposing these systems about the turbine shell during separation processes provides a comprehensive, accurate and documented record of shell displacements which may assist technicians during separation processes.

Specifically, referring toFIG. 1 , a schematic illustration of asystem 100 connected to aturbine 90 which includes afirst shell portion 94 and asecond shell portion 92 is shown in accordance with aspects of the invention.System 100 may include afirst member 110 connected tofirst shell portion 94 and asecond member 120 connected tosecond shell portion 92.First member 110 andsecond member 120 may be communicatively connected to one another via ameasurement device 130 which is adapted to monitor a position offirst member 110 relative tosecond member 120. Based on the position offirst member 110 relative tosecond member 120, a technician and/orsystem 100 may monitor a set of displacement values (e.g., distance betweenfirst shell portion 94 andsecond shell portion 92, a joint width, vertical movement ofsecond shell portion 92, etc.), for ajoint 96 betweensecond shell portion 92 andfirst shell portion 94. In one embodiment, at least one offirst member 110 andsecond member 120 may include a set of magnetic components adapted to attach toturbine 90 and thereby securefirst member 110 and/orsecond member 120 toturbine 90. It is understood that attachment uponturbine 90 byfirst member 110 andsecond member 120 may be accomplished in any number or combination of ways as is known in the art or discussed further below. - In an embodiment of the present invention, during a separation process (e.g., lifting of second shell portion 92), a technician may obtain a set of displacement values and/or monitor a distance between
first shell portion 94 andsecond shell portion 92 by monitoringfirst member 110,second member 120, and/ormeasurement device 130.
