Section 2 - Installation and Alignment

The following descriptions are intended as a guide in properly setting up and checking the alignment of theturbine. No attempt should be made to install the turbine before these instructions are read and thoroughly under-stood.

NOTE

The oil system, the HP end speed pick-up enclosure and all electrical junctionboxes are protected against airborne corrosion by Zerust Vapor Capsules. Thesecapsules emit an invisible, odorless, non-toxic vapor which protects the metal sur-faces against atmospheric corrosion. To avoid deterioration of the vapor protec-tion, this area must be kept sealed until ready for installation.

At installation, all preservation capsules must be removed before start-up. See andFig. A34 for location and number of capsules enclosed in this unit. Areas contain-ing Zerust capsules are also identified by highly visible yellow tags.

WARNING

The Zerust Vapor Capsules must not be disassembled in order to preventcontact with the active ingredients. For additional information, see proce-dure instruction 165A976RA found later in this section of the manual. I

INSTALLATION

The following instruction is intended as a supplement to the field alignment instruction 165A705BR whichfollows in this section of the manual. The instructions below assume the foundation has been properly prepared andanchor posts and anchor bolt locations have been verified.

The turbine will be received as a preassembled, base mounted package. The oil system is a separate package.Because of shipping limitations and/or to avoid potential damage, certain components may be removed for shipment(refer to shipping documents for list of ship loose items). Refer to the mechanical outline, Fig. AOl, and the oil sys-tem outline, Fig. Al8 for arrangement and external connection points. The recommended sequence of erection isas follows:

NOTE

The alignment steps contained herein are to be used as a guide for installing thesteam turbine and generator. Other methods/procedures may be used by the instal-ling contractor and as long as they are reviewed and found to be acceptable to theGE Technical Director, they will be considered acceptable by the manufacturer.

1 . Position the jacking blocks so they will support the turbine base at the mounting pad locations as shownon sheet #9 of Fig. AOl.

2 . The 1.50 inch jacking bolts are intended to aid in positioning the base during alignment. These boltsshould never be used to help support he turbine during normal operation. Check to assure bolts and

threaded holes in base are clean, free of burrs and well lubricated before use. The use of auxiliary jackswill make turning of the jack bolts easier.

3. The turbine-base package should be properly rigged and lifted (see lifting arrangement, Fig. MB).Thoroughly clean the bottom of the turbine base with mineral spirits then set on the foundation. Thejacking block locations may have to be altered to be aligned with jack bolts.

4 . Remove temporary shipping braces (painted yellow) which were used to provide additional supportduring shipment. The one exception is the front standard gagging studs (see Fig. LO1 parts 19,20 and52) which must be removed after the turbine is aligned, but just before grouting.

5 . Using a precision optical transit, set the turbine-base elevation to have all the factory base optical pads(top surfaces) at zero reference elevation with respect to each other (tolerance MO5 inch [. 127rnrnl).These pads are welded to edges of base HP and LP mounting pads.

6 . Once the optical pad reference elevations readings are within tolerance, remove shim (9), screws (lo),gagging studs (52), nuts (19) and collars (20) between front standard and HP casing. Next, the alignmentpin (3 1) at the lower front standard to HP shell transverse horn should be tried. Alignment will be com-plete when this pin fits smoothly and the optical readings match the factory readings. Gagging studs,collars and nuts should be stored away for re-use in the event it is necessary to remove trunnion pins,see page 2-4.

r

7 . Remove rotor locking brace and upper half of HP bearing cap.

8 . Review generator installation instructions and the generator outline in the Generator Section of thismanual.

9 . The solid flanged coupling spool piece (Fig. D 18) must be coupled to the turbine rotor prior to settingthe generator. See page 2-6 for fastener tightening information.

2-2

P&o power G E K 105632

10 . Align the generator rotor to the turbine (coupling spool piece) to obtain the cold coupling rim and faceindicator readings per 165A705BR.

NOTE

The turbine thrust and journal bearings have been preserved with ESGARD pre-servative (see Section 4 for description). This allows the turbine shaft to be rotatedfor alignment purposes without the need to disassemble, clean and lubricate thebearings.

11 . Grout the turbine base and anchor bolt sleeves after all alignment (turbine and generator) has been com-pleted. Recheck coupling alignment once grout has cured, then final torque all anchor bolts. Fill anchorpost “KA” box at HP end with Chock Fast Orange epoxy grout (supplied by the installation contractor).The LP end anchor post “KB” is to have the base alignment plate fitted and welded per the mechanicaloutline Fig. AOl, sheet 9.

CAUTION

The alignment pin mentioned in step 6 must never be left in place except forchecking alignment. Remove for operation.

12 . After grouting of the base is complete and grout has been aged to achieve full strength, it is recom-mended that the base longitudinal beams be cut through with a minimum gap between cut ends of l/2”.The cut ends should be ground smooth to remove hazardous burrs and sharp edges and then painted toavoid corrosion. The function of the beams is to provide stability between the HP and LP modules forlifting and transportation. Once the modules are anchored, the beams are no longer needed. However,heating and subsequent expansion of the beams during normal operation can result in very high forcesthat can buckle the beams, distort the HP and LP modules and possibly cause turbine shaft/bearing mis-alignment and damage. Cutting though the beams will eliminate these possibilities.

NOTES

a.. Before bolting the trip throttle valve to the turbine, adjust the spring supportby jacking the valve into alignment with the turbine inlet flange. The springsupport is carrying the weight of the valve at this point while an overhead cranebalances the valve. Bolt the trip throttle alve to the turbine. Once the valve isbolted to the turbine refer to mechanical outline, Fig. A01 and jack the springsupport and additional amount equal to the value shown in the table of free ex-pansion for connection “AA”in the vertical (+Y) direction. The spring supportwill then carry the full weight of the trip throttle valve when the turbine is inthe hot (expanded) condition.

b . Refer to GEK 50805A in the Bulletins section of this manual for GE suggestedgrouting procedures.

c . When assembling the inlet steam piping and the extraction steam line piping,be sure that no strain is put on the turbine and that all hangers and supports areproperly adjusted. Be sure to include gaskets at all flanged connections.

d . Prior to start-up, lubricate HP Standard trunion pins per instructions on page2-4 and the exhaust casing side supports per instruction on page 2-5.

LUBRICATION OF TRUNNION PINS

The turbine HP casing is supported vertically and positioned axially on the front standard by (2) trunnionpins. Sliding action in the transverse direction occurs between the casing shell arms and fixed pins as the casing ex-pands and contracts during temperature changes. The pins also provide a pivot as the casing expands vertically. Toprevent binding between the pins and the casing shell arms lubrication with grease is required prior to initial start-upand about every three months therefter.

A grease fitting is provided on the top of each casing arm (4 total) which will conduct lubricant throughdrilled passages to circumferential grooves in the trunnion pins. The sketch below shows the location of the greasefittings. A high temperature, rust inhibited grease such as Mobil - Plex #47 Shell - Dolium “R” or Texaco Pre-mien RBRB is recommended.

CAUTION

If the trunnion pins are to be removed for any reason, the casing must be securedaxially from movement when the pins are removed because of the tension loadexerted on the pins by the exhaust casing flex-legs in the “cold” condition. Fail-ure to do so could result in equipment damage or personal injury. The gaggingstud and nuts used for shipping can be re-used for this purpose (see item 6, page2-2).

LUBRICATION OF EXHAUST (SLIDING) SIDE SUPPORTS

The axial exhaust casing side supports are fastened to the LP supports by an arrangement utilizing spacerbushings and washers which allows the casing supports to slide on the mounting~surface when temperature changestake place. This sliding action occurs between two steel parts when under the load of the turbine weight. In orderto prevent binding between these surfaces, lubrication with grease is required prior to initial start-up and about everythree months thereafter.

l3vo grease fittings are provided on the LP supports which will conduct lubricant through drilled passagesand grooves to the mating surfaces. A fillet of grease around the support plates will aid in excluding moisture andforeign materials. The sketch shown below gives the approximate locations of the grease fittings. A high tempera-ture, rust inhibited grease such as Mobil - Plex #47, Shell - Dolium “R” or Texaco Premium RBRB grease isrecommended. During major maintenance periods the old grease should be rinsed away with a good solvent, thenforce a liberal supply of new grease on the sliding surfaces.

CAUTION

Jacking bolts and brackets are to be removed after final alignment, to allow forthermal expansion. Failure to do so may result in serious equipment damage.
