1 Scope

This section contains general information and advice on pump maintenance procedures for a horizontal pumpset. These general instructions are provided as guidelines to aid and direct a safe and efficient maintenance project.

It is essential that the plant safety rules and regulations are observed at all times during maintenance procecdures.

Note: The boiler feed pump is an integral part of the pumpset. The following

instructions should, therefore, be read in conjunction with those for the

booster pump and the associated equipment.

1.1 Equipment Condition

1.1.1 Performance Record

Keep a written performance log for the equipment. An ongoing performance record will assist troubleshooting and future pump service decisions. Long shutdowns and

unnecessary expense can then be avoided.

Pressure indicators can be installed into tapped openings in the suction and discharge nozzles to provide much of the data required for performance analysis.

Periodic trending vibration recordings are necessary to diagnose excessive vibration

levels.

1.1.2 Troubleshooting

Analyse performance before dismantling. A problem might be correctable without

dismantling the pump. A performance record will help narrow the possible causes, and determine whether the problem is mechanical, hydraulic or system related.

System problems typically originate in the suction system side of the pump. Control

mal-adjustments should be eliminated. Mechanical and hydraulic problems often are

interrelated and the source can be difficult to identify. Refer to Troubleshooting. 1.2 General Overhaul Information and Advice

Dismantling

Check for toxic or otherwise harmful fluids before loosening bolted joints or

pipe connections.

Collect and dispose of toxic or otherwise harmful fluids in accordance with

the current environmental regulations to prevent endangering people or the

environment.

- Before starting any maintenance activity, ensure that:

-

Electrical power breakers are locked in the OFF position. -

The pump is at ambient temperature. -

Pump system pressure has been isolated. -

The pump is drained and vented (by removing drain plugs or opening valves as applicable). -

Suction, discharge, and auxiliary piping valves are closed. -

Cap the ends of all disconnected pipework to prevent the entry of dirt. -

During any dismantling procedure, mark all removed parts to enable replacement in the same position. - Protect all parts. Place larger parts in a protected area and wrap in cloth or

plastic. Place smaller parts and bolting in bags or boxes, and identify with

labels where components are for re-assembly.

-

Protect screwed joints and threads. - Refer to each dismantling / assembly section for information on specific

requirements for special tools and equipment. Obtain any required items

before starting maintenance activities.

- Check pump rotation. Note that certain threaded shaft components may be

tightened against rotation and may have a left-hand thread.

At all stages during dismantling of the pump, it is essential that the pump

shaft is adequately supported to prevent bending and/or damage to the

bearings.

Assembly

When the supplied pump and pumpset equipment is classified as suitable for

use in a Hazardous Area, the following conditions during maintenance

procedures MAY invalidate the Hazardous Area classification and MUST be

avoided:

? failure to maintain correct casing / impeller / bearing clearances, as

detailed in Pump Unit Data

? failure to use NEW O-ring seals, gaskets, seals or nut locking devices of

the correct type and size at all appropriate stages during assembly

procedures

? failure to maintain bearings correctly

? failure to re-connect main (suction and discharge) pipework correctly to

the pump casing in accordance with manufacturer’s information and

current regulations

?failure to re-connect auxiliary pipework correctly in accordance with manufacturer’s information and current regulations and to direct the vent and drain pipework to suitable safe locations / containers

?failure to re-connect electrical equipment power supply and control cables and instrument cables correctly in accordance with manufacturer’s

information and current regulations

?failure to ensure correct direction of rotation for the driver in accordance with manufacturer’s information

?failure to install the coupling spacer(s) and coupling guard(s) correctly in accordance with manufacturer’s information and current regulations

- All parts must be absolutely clean and free of oil or dust. Technical grade acetone is recommended for cleaning machined surfaces immediately before assembly. Air dry (use filtered, dry air) cleaned parts in a dust-free area. The rust inhibitor on machined surfaces should be removed with a suitable solvent.

Ensure that there is no paint on locating spigots or recesses.

- Handle all parts carefully so that they are not dropped, or damaged in any other way.

- Ensure any burrs or dirt on the faces of sleeves and impeller bores are removed. Anti-scuffing paste must be applied to sleeves and impeller bores to facilitate later dismantling.

- New gaskets, seals and O-ring seals of the same material, type and size as originally supplied must be used for re-assembly operations. The O-rings must be fitted carefully to prevent the risk of damage.

- Powdered molybdenum disulphide can be used as a shaft lubricant.

- Lubricate screwed joints and threads with glycerine

or ’Polytetrafluoroethylene’.

- When applicable, re-assemble small bore pipework using new plugs in unions that have been disconnected.

At all stages during assembly of the pump, it is essential that the pump

shaft is adequately supported to prevent bending and/or damage to the

bearings.

1.3 Shipping From Site

All equipment must be completely drained and decontaminated before removal from site.

1.4 Completion of Pump Overhaul

Re - commission the pump following every overhaul. Refer to BOILER FEED PUMP SET INSTALLATION AND OPERATION INSTRUCTION.

3.2.2.2 Examination of Bearings

Thrust Bearings

Inspect every thrust bearing pad. Renew pads if they show extreme wear,

scratches, or any 'smearing' of the babbitt lining. New and used pads should not be

mixed. If a pad must be renewed, renew all pads on that side of the bearing.

Prevent damage to the thrust collar bore and bearing surfaces.

Inspect both faces of the thrust bearing collar. The running surfaces should be

smooth. Replacement is generally recommended, but a rough surface can be

ground or lapped if proper equipment is available.

Check the run-out of a re-worked collar after it is refitted to the shaft. The maximum

allowed TIR is 0.01 mm.

When new axial bearing parts are being fitted, or if the running surfaces of the thrust

bearing collar have been ground or lapped, check the axial clearance in the thrust

bearing. If necessary, correct the bearing axial clearance by replacing the brass shims fitted behind the thrust pad assembly end-plates with shims of the required thickness.

The new axial clearance of the thrust bearing pads is shown on the Longitudinal Section drawing.

The amount of shimming on the thrust bearing assemblies also determines the axial

position of the rotor. It is important that should the axial position have to be adjusted for any reason, the total amount of shimming should remain the same to preserve the

correct axial clearance;i.e. shims removed from one side of the thrust bearing must be inserted at the other side.

Journal bearings

Visually inspect the radial sleeve bearing surfaces for excessive scoring and heat

damage. Check the wear pattern on the running surfaces, the bearings and the

shaft. Renew the bearings if excessive wear or damage is present.

Bearing Housing

Check bearing housing fits, filing off any interference points. Remove old sealant

from housing flanges.

3.2.2.3 Assembly

If the removed bearing housing is refitted to the same cartridge inner block,

the rotating parts are positioned correctly by the dowel pins. During

re-assembly of the housing, the only requirement is to re-locate the lower

bearing housing correctly with the dowel pins. If a different cartridge inner

block, or a different bearing housing, is to be fitted, positioning of rotor parts must be checked. Refer to Manufacturer for advice.

Note: Ensure that the NDE labyrinth seal and the coupling are installed before
