PROCEDURE FOR LEVELLING & GROUTING OF BASE FRAME AT SITE( FOR HDA / HDB / HG / CHT PUMPS ONLY )

PURPOSE :

High speed rotory equipment needs to be installed with maximum contact area between base frameand the foundation. To achieve this conventionally, blue matching procedure is adopted between packerplates and foundation. This calls for skilled millwright fitters to work on and consumes lot of time.Despite this, the contact area achieved is nowhere near 100%.

Therefore, the following procedure is recommended which ensures :

1. Nearly 100% contact area between the foundation, the packer plates and the base frame.2. Considerable saving in time and manpower.

PREPARATION :

The following preparation is followed, in case the base frame and the packer plates ( equal to thenumber of foundation bolts ) are in scope of KSB. Otherwise, the user is requested to follow thepreparation as under :

l The base frame is provided with the pads, which are welded at the bottom, machined in one settingand drilled to 15 mm. Dia. ( Ref. Fig. 1).

l Machined packer plates, having 0.02 mm. face parallality, and of the dimensions equal to thewelded pads at the bottom of the base frame, are required with tapping of M 10. These packer platesare to be bolted with pads at the bottom of the base frame, using M10 bolts ( Ref. Fig. 2 & 3 ).

PROCEDURE :

01.Bolt the pump on the base frame.

02.Bolt the packer plates on the bottom pads of the base frame.

03.Place the unit on the foundation.

04.Suspend foundation bolts into the pockets provided on the foundation blocks.

05.Level the pump on the delivery flange or feet, within 0.04 mm. per meter, using jacking bolts pro

vided at the corners of the base frame.

06.Grout the foundation bolts and the packer plates by using quick setting non-shrink cement, ACC

make ‘Shrinkkomp’ or Forsoc make ‘Cobextra-GP2’ or equivalent ( Ref. Fig. 4 ).

07.Allow curing time of 24 to 72 hours depending upon the grout used.

08.Remove M 10 bolts, which are holding packer plates with the base frame.

09.Carry out final levelling by inserting shims (SS shims preferred) between packer plates and the base

frame.

10.Tighten the foundation bolts and recheck the levelling. Correct it, if necessary.

11.Grout the complete base frame, including the hollow portion, if any, using conventional grouting mix, i.e.,

portland cement, sand and aggregate in proportion 1 : 2 : 2 and gravel size not to exceed 20 mm.

12.Plaster the foundation and apply suitable oil resistant paint.

GEAR-FLEX COUPLING

CROWNING OF GEAR TEETH (OPTIONAL)

The straight line tooth form is known to transmit high torque when thecenters of axis are in complete alignment. Where there is anydisplacement, however, this will cause the contact area to localize on toothsurface (at the end of tip of the tooth) thereby causing damage to surfacesof the teeth.

While rotating the load is continually changing location, introducingsliding between the two gears. Crowned gear teeth resist the wear thusdeveloped. Because of the fully crowned design, end bearing does notoccur, and the tooth bearing remains near the center section of the tooth,thus utilizing the additional strength available at the tooth centre.

The LOVEJOY Gear coupling has a unique crowning for the tooth surfacewhich is designed after full consideration of the relationship between toothforms & tooth width so that the contact stress on the tooth surface will notvary significantly even where relative movement is present. As for thetooth tip, the crowning is applied & the tooth is designed to minimise thetop clearance between teeth when they are mated.

The LOVEJOY Gear coupling has a crown tooth form so as to givemaximum tooth thickness at its center. Where there is a relativemisalignment between the driver & driven shaft, it is necessary that thetooth which comes between the teeth of its counterpart be permitted tooscillate. The internal teeth of the sleeves have a std. form whereas theexternal teeth of the hub take a special form.

GEAR-FLEX COUPLING

HALF FLEX COUPLINGS WITH FLOATING SHAFTS

A floating shaft can eliminate the need for additional bearing support alongspanning shaft because shaft is supported at ends by connectedequipment through the half flex couplings. These are generally used forthe applications of cooling tower fans.

Flexible hubs on floating shaft (Fig. 3a )Assembly of flexible hubs on the floating shaft allows for easierreplacement in case of wear & allows the rigid hubs with their increasedbore capacities to be used on the connected equipment shafts. Thisfrequently means a smaller coupling size to be utilised.

Rigid hubs on floating shaft (Fig. 3b )When the rigid hubs are on floating shaft, shorter shaft spans can beaccommodated. Since the flexible hubs are outboard, the planes of gearmesh are further apart, providing greater misalignment capacity.

GEAR-FLEX COUPLING

LUBRICANTS

1. OIL LUBRICATION

For the gear coupling, use gear oil of viscosity of 35 to 45 cst at 99°C withextra high pressure additive. Where the coupling is used under extremeoverload operation, severe reversing operation or bigger angular and offsetmisalignment, use gear oil of viscosity of 70 to 110 cst at 99°C.

A. First filling must be ample.

B. After about 3 months’ operation, the coupling should be overhauledand drained of used oil to remove abrasion particles, and refilled withfresh oil.

C. Subsequent refilling or replacing of oil should be made every 1 year byuse of oil plug holes.

2. GREASE LUBRICATION

Grease lubrication is somewhat inferior to application of gear oil.

Coat the coupling case and coupling center with the specified grease untilthe teeth are submerged in grease, assemble the coupling, tighten the boltsand then supplement grease through oil plug hole by use of grease gunand so on.

Replacing time of grease is same as gear oil, but replace old grease withnew grease in full by overhauling the coupling.

3. RECOMMENDED LUBRICANTS

Recommended Grease is RSG (Rathi Special Grease) havingδδδδg = 910 Kg/m3.

Refer Table ‘C’ for grease qty. reqd. per coupling size.

GEAR-FLEX COUPLING

INSTALLATION INSTRUCTIONSFOR STD. LFG / LHG COUPLINGS

(A) BEFORE INSTALLATION

1. Remove the coupling from packing & thoroughly inspect forsigns of damage.

2. Disassemble the coupling by removing nuts & bolts. Clean allthe parts carefully.

3. Remove protective coatings / lubricants from bores &keyways.

(B) MOUNTING PROCEDURE

1. Slide the sleeves with internal teeth with rubber O ring onshafts before mounting the hubs.

2. Mount the hubs with external teeth on their respective shaftsflushed with the faces of hubs as shown in fig. 1.

20 JAN-02

Page 133: Feed Pump KSB

GEAR-FLEX COUPLING

3. With one machine firmly bolted down, set the equipments ata distance ‘G’ (refer table A & B) between shaft ends by using aspacer bar equal in thickness to the required gap ‘G’ as shownin fig. 2.

Deviation in standard DBSE is defined as axial misalignment (endfloat). For normal applications the shaft end should be flushed withinner face of the adpater. In some special cases the shaft ends mayprotrude beyond the inner face of the adapter or may remain inside,if required. The distance between two faces of adapter flanges is tobe maintained as specified. The variation in this distance should notexceed the permissible initial axial misalignment given in table 1.

GEAR-FLEX COUPLING

(C) ALIGNMENT PROCEDURE

Alignment procedure is given separately for each type of alignment,for simplicity. However all 3 types of misalignments may be presentat the same time.

IMPORTANT : The misalignment capabilities shown in drawings or inproduct literature are for dynamic conditions and variations.For optimum service from the coupling the installation misalignment(Initial misalignment) should not be more than 25% of the maximumallowable misalignments limits. Allowance should be made for anyanticipated movements which will occure during operation (e.g. Thermalmovements).

For Permissible INITIAL misalignments refer table A

For Permissible MAXIMUM misalignments refer table B

Page 135: Feed Pump KSB

GEAR-FLEX COUPLING

(I) CHECKING PARALLEL /RADIAL ALIGNMENT

Check the parallel/Radial alignment with the help of straightedge resting squarely on both the hubs at 4 places 90° apart.The deviation in the readings should not exceed the permissibleinitial parallel misalignment mentioned in table A. (Refer fig. 3)

(II) CHECKING ANGULAR ALIGNMENT

Check the angular misalignment with the help of slip gauges byinserting in the gap at 4 places 90° apart. The deviation in thevalues of standard gap ‘G’ is Total Indicated Reading (TIR). Theangular misalignment ‘X’ in mm is half the Total IndicatedReading. The values of angular misalignment should not exceedpermissible initial misalignments mentioned in table A. (Referfig. 4).

GEAR-FLEX COUPLING

(D). ASSEMBLY PROCEDURE

IMPORTANT : If the coupling is dynamically balanced, ensure thatthe matchmarks are in straight line & unidirectional before boltingthe assembly.

1. Insert the gasket between the flanges. Position the flangedsleeves with lubrication plugs.

2. Insert the bolts & tighten the nuts.

Remember: Assemble only with the help of the fastenersfurnished with the coupling.

Fig. 5

3. Fill with recommended grease/oil (RSG/RSL with reqd. qty.)for lubrication. For grease quantity for respective couplingsize, refer table No. C.

4. Change the grease after the interval of 6 months & the oilafter the interval of 1 year or after 8000 working hours.

Use Loctite to prevent the loosening of threads, if required.

IMPORTANT: The necessity for shields & guards varies with individualinstallations. The owner or user must provide the required safety guards. Safetyguards or shields are not furnished by us with this equipments.

1.0 Dangers and safety precautions

Minimum flow valves have the same potential danger as pressure vessels.Therefore planning, installation, operation and maintenace shall be doneaccording the necessary safety precautions.

1.1. Danger to persons and materials

The minimum flow valves should only be operated within their limits ofdesign and layout.

No changes are to be made without our approval.Only use original spare parts.

Safety regulations, site regulations and installation safety precautions areto be followed.

Please follow the instructions as given in this “Installation-, Maintenanceand Assembly instructions”.

1.2 Avoid dangers

Maintenance of the Automatic Recirculation Valve shall only be done bytrained personnel.

Before disassembly, the installation has to be shut off and the valvepressureless and cooled down. Please make sure that these safetyprecautions can only be cancelled after ending the assembly of the valve.

Please be aware that also in a pressureless valve there might still bemedium.

Wear protective clothing.

2. Description

The Schroedahl automatic-recirculation-valve model TDM is appliedin centrifugal pump systems in order to provide an automaticleak-off flow in case of low load conditions.

The application range of the series TDM with a multistage pressurelet-down section is, independent of the temperature, for theoperating pressures from 64 bar (a) to 250 bar (a) (900 psig to 3600 psig).The valve consists of an upper and a lower housing, each providedwith a flange. The bypass housing, and as an option also the start-uphousing, are located horizontally at the side of the valve. The valve trimcomprises a check valve as also a control- and throttle section.

The valve protects centrifugal pumps, especially boiler feed pumps,against overheating, by maintaining, automatically, a minimum flow.At flows, lower than the required minimum flow the check valveactivates, by means of a lever, a vortex plug.When lifted of its seat, the vortex plug allows a flow through thepressure reduction section to the suction tank (or condensate tank).

The opening characteristic is linear; the bypass flow increases whenthe check valve moves from its switch point further into the closesposition. Because of the modulation bypass control, the total ofprocess flow and minimum flow remains approximately constant.

The check valve, shaped like a differential control piston and springloaded, has such a high own frequency, that waterhammer is avoided.The check valve dampens pulsations because of its throttling effecton the mainflow and stabilises unstable pump characteristics in thepartial load range.

The housing is made from forged steel and is provided with a chromiumsteel liner in the check valve area.All moving parts and guides consist of alloy steel which arecompatible. Alternative materials are available as options(see drawing and parts lists).

3. Packing and marking

The automatic recirculation valve is shipped, depending on size, inan aluminium box (reusable), skid-carton or in a wooden crate.The standard factory conservation is sufficient to protect the valvefor a period of approx. 6 month (the stocking area should be dryand ventilated).If special packing or conservation is required, this should bestated with the order.Specific valve data are indicated on the valve nameplate as persample below.The valve nameplate is attached to every valve housing.

If spare parts are required, the following valve date should beprovided with the inquiry (order):production number K ........ (stamped in valve body), valve modelnumber and part number (check parts list).

4. Assembly and disassembly

The automatic recirculation valve type TDM is usually installedvertically, with the mainflow upward, and directly on the pumpdischarge flange.The bypass housing is connected to the bypass piping (and the pipingconsequently to the feedwater tank or other tank), so that a recirculationflow will be possible.Other installation positions of the valve (horizontal, upside-down) arepossible, if so ordered only!No special tools are required for the installation, assembly or disassemblyof the valve.

4.1 Installation at the jobsite

In order to prevent damage to the flange finish and/or the bolts thecomplete valve should be installed in the piping free of tension/ stress.Before tightening the bolts with a torque wrench (torques as recommendedby the factory!), please ensure that the machined flange surfaces andpacking rings are clean.

4.2 Disassembly of the TDM

Remove the TDM from the piping system. Disassemble bypass housingPos. 09. Pull the bypass trim „M“ out of the assembly (careful!).Apply a screwdriver between the collar of the control head(pos. 11) and the valvebody (pos. 01).Remove the upper body (pos. 02) from the lower body (pos. 01) byloosening the hexagon nuts (pos. 28).The check valve (pos. 07) and spring (pos. 06) can now be removedfrom the lower body (pos. 01).Clean all parts and check for any damages. In case of damagedseats (check valve seat or bypass seat), this should be repairedby lapping the respective parts on the seats.Replace ring (pos. 30) if required.

4.3 Assembly of the TDM

Replace the check valve (pos. 07) with the spring (pos. 06) in thelower body (pos. 01).Now the upper body (pos. 02) is placed on the lower body (pos. 01)and the hexagon nuts (pos. 28) are tightened (check cross sectionaldrawing!).Carefully insert the bypass section „M“ in the valve body andas certain, that lever (pos. 13) fits (slides) in the slot in thecheck valve (pos. 07).The bypass housing (pos. 09) with the bypass orifice (pos. 23) is nowcarefully replaced and tightened to the housing (pos. 01) with thehexagon nuts (pos. 29).

4.4 Disassembly of the bypass section

Occasionally, and because of contamination of the fluid, a completedisassembly of the bypass trim may be required. At each inspectionthe bypass should be checked for proper operation. In case ofdamages, the bypass section should be removed, disassembled andthe damaged parts replaced.

Inspection- Check the seating of the vortex plug (pos. 12) and the vortex

bushing (pos.10) for any damages.

- When damaged the vortex plug and vortex bushing should bereplaced as an unit.

- Check glyd-rings pos. 33.1, 34.1 and 35.1 for any damages.

NoteIn case of doubt the complete bypass assembly pos. 10-16, 21, 23,31-36 may be replaced and the dissassemdled bypass may be sendto the factory for repair.Check the drill plate pos. 23 for any damages. Replace the completeseal set.

4.5 Assembly of the bypass sections

Proceed in the reverse order as per disassembly instruction above.

5. Commissioning of the TDM

The valve is commissioned together with the pump. When the mainshut-off valve in the pump discharge piping (to the boiler or process)the specified bypass flow is maintained through the bypass section(and to the piping of the bypass system).By closing or opening the main shut-off valve, the opening and closingof the bypass can be checked. The switch point of the valve can beestablished acoustically (use a technical stethoscope or even ascrewdriver to the ear will do).In case a manual start-up connection is provided on the valve, theminimum flow is achieved through this section. The automatic bypass isclosed during commissioning and the manual start-up is opened. Theautomatic bypass section is spared (protected) during commissioning inthis way, as the fluid might still be contaminated and/or carry solids!

6. Maintenance instructions

The TDM has been designed so, that no special maintenance is required.Maintenance is restricted to cleaning the trim together with the pumpat regular intervals.After disassembly of the valve, all seals should be replaced (by newseals) before re-assembly of the valve.

7. Warranty conditions

If no special conditions have been agreed upon the order, the warrantyis limited to 24 month after shipment or 8000 hours of operation.The warranty does not include damage caused by improper handling, dirtin the system or normal wear.
