Operating instructions for centrifugal pumps

1.0 General Directions Every pump is subjected to a trial run on our test field and delivered in a fully operational shape . The present Operating Instructions are intended to inform the operators an expert exploitation . No liability would be assumed for damages resulting from the inobservation of these instructions . A guarantee within the framework of our terms of delivery would be granted only if the pump is being used

for the service conditions identified and confirmed ( rating plate ) In all queries and spare parts orders , please state the following details: ( See rating plate ) 1. Works No. 2. Pump Type / Size 3. Year of Manufacture 4. Designation of the replacement parts needed , by specifying the sectional drawing number and parts items . Should the pumping set not immediately be taken into operation , then check the pump interior for humidity

and dry it out . A means of preservation should be applied in case of a prolonged storing period .

2.0 Installation of Pump The resident superintendents has to advise the erection personnel of the safety requirements and of

particular local regulations . Connection of the pump to the piping system has to be established free of any stresses , which means that all

forces and moments resulting from the system are to be intercepted before junction points . Where the pump is delivered without drive motor , the electric motor has to be carefully sighted via the

coupling and the alignment be checked according to appendix A. If non steel pipes are employed for the sea-water pump line, such as inside coated or CuNiFe pipes, the

sacrifice pipe or the anode (Zn or Fe) must be always installed near the pump suction. After installation of the pump aggregate, the alignment of the flexible coupling must be checked

according to appendix A. Final Check: The pumping set must allow for an easy manual rotation on the coupling . Verification of the Sense of Rotation: The sense of rotation must coincide with the rotation sense arrow shown on the pump . Verify the sense of rotation by shortly starting the drive of the liquid filled pump.

3.0 Commissioning / Stopping 3.1 Preparation: Fill the volute casing of the pump with the medium to be conveyed . Open the suction sided shut-off fitting for full passage . 3.2 Starting: Start up the pump against the closed pressure gate valve .

As soon as the pump commences delivery with its full discharge power ( pressure increase on delivery sided pressure gauge ) , slowly open the shut-off fitting . ( An extended run of the pump against the closed shut-off fitting is not permitted . Inadmissible heating ) The pump must be protected against back flow (non-return flaps on the suction and delivery side) and pressure shocks.

3.3 Stopping: Close the pressure gate valve .

In the presence of non-return fittings ( pressure sided ) , the pump may be stopped without taking any further measures .


Page 2 of 8

3.4 Shutdown:

If the pump is not used for prolonged periods , clean and preserve all components . Store the pumping set in a dry state .

For the stand-by-pumps care is to be taken , that the pump shaft will be turned appr. twice a week to avoid damages of the bearings by vibration .

4.0 Operational Supervision 4.1 Operating Point:

Continuously supervise the operational discharge head of the pump ( for data refer to rating plate ) as the difference of the pressure readings between pressure and suction flanges of the pump .Correct it by a regulating fitting to be provided on the discharge side .

4.2 Bearings: Pump Type VNF :

Attention! Leakage holes at bearing seat must be always open in case mechanical seal is leaking - so that no water can run into the bearings ! Regularly check the running noise of the bearings . A uniform , purring sound is audible in the event of an unobjectionable bearing contact .

Damaged bearings cause a loud , irregular , chattering noise . (In such a case, examine the bearings.) 4.3 Shaft Seals: Shaft seals must never run dry , not even for short periods ! 4.3.1Mechanical Gland Seals:

In operation , mechanical gland seals are running free of leakages , which means that the low quantity of conveying medium required for lubrication evaporates when escaping from the sealing gap . Supervise the escape of leaking water in the range of the seal or at the checking outlet . If a drop by-drop escape of fluid is exceeded , then examine the mechanical gland seal .

Replace it , if necessary . 4.3.2Stuffing Boxes:

When using packing material ( stuffing box ) , allow for a generous leakage during the running-in period ( about 2 hours ) of the packing rings . During the further operation , uniformly read-just the stuffing box gland until the leakage decreases to the desired minimum ( slight dripping ) . During this procedure , check shaft and stuffing box for temperature rise. In the event of symptoms for overheating , do not tighten the gland any further but slacken it slightly so as to again achieve the normal temperature by an increased leakage . Afterwards , slightly readjust the gland until the escape of leakage is again under control . If both temperature and tightness have themselves adjusted to a uniform value , a check is still required at prolonged time intervals .

4.4 Suction Sided Fittings: All fittings ( filters , butterfly valves , gate valves etc. ) are to be continuously examined for full passage

.

5.0 Maintenance 5.1 Bearings (Pump) All pumps are delivered with grease lubricated rolling contact bearings . Regrease through a grease nipple by using a grease gun .

The regreasing intervals and the quantities of grease to be refilled are obvious from the table given below .

During all disassemblies - but not exceeding 4 years - carefully clean the bearings from old grease residues . then reintroduce the new charge by spreading or refilling bearing grease into all bearing cavities between the rolling elements .

As a lubricant , use quality rolling contact bearing greases having the following specification : Saponification basis: LITHIUM with anti-corrosion additives , water repellent Dripping point: about 190C . Handling temperatures: -30C up to +120C . Walk penetration: 250 to 295 Standard: SEB 181252 SEB 18103 K3K

5.2 Mechanical Gland Seal


Page 4 of 8

Mechanical gland seals do not necessitate any particular maintenance during operation . 5.3 Stuffing Boxes

Stuffing box packings must not seal definitely tight . A dripping leakage is necessary to prevent overheating or even burning of the packing due to frictional heat .

Retighten the packing in compliance with item 4.3 in the event of heavy leakage . Commence with replacing individual packing rings in case of a corresponding wear-down ( 2 rings at

8.0 Description of the Priming Pump (Liquid Seal Pump) The liquid seal priming pump consists of the air pump housing and bladed air pump impeller . The bladed impeller is mounted on the same shaft as the rotor . It is fitted into the air pump housing but with sufficient clearance to prevent wear of the housing walls . After the priming pump has been primed with the medium to be handled , a ring of liquid is formed in the pump housing as a result of the centrifugal force set up by the rotation of the bladed impeller , and a sickle-shaped working space is formed around the hub of the impeller . This working space is divided by the blades into individual chambers , the liquid ring being first enlarged and then reduced during rotation . With cubical expansion the air or the liquid is drawn in through the suction slot , and with cubical contraction it is ejected through the pressure slot . The air pump is set in such a way that it can withdraw from the rear of the rotor through ducts provided for the purpose , the control cock being set to "Ansaugen"(suction) . At first , an air/water mixture is forcefully ejected ; this continues until a regular flow of water establishes itself . The pump is now filled with water and delivery starts automatically . This is the end of the priming period , the control cock is set to "Betrieb"(operation) and the water drawn in is constantly circulated through the pump .

9.0 Alignment for flexible coupling When aligning the coupling halves, the angular and parallel offset misalignments of shafts relative to each other should be as small as possible. Alignment to be carried out in two planes as shown in fig. 1.1 with a straight edge (offset misalignment) and spacer bar (angular misalignment). A dial indicator will give greater accuracy. Fig. 1.1

1. Commissioning

For commissioning pay attention to following steps:- Check all pipe connections and pipes for proper lay and leakage.- Check all electrical connections.- Check the compressed air connection

Caution

Please pay attention to modification for special design.

2. Maintenance and repair

The system functions with slightly maintenance work. Following inspections respectively work should be performedin fixed intervals which depend on pumping medium, operation mode and operation time.- Check all components for proper function

2.1 Disassembly and assembly of the compressed air ejector

Before starting work, the compressed air ejector must be switched to a power off mode.

Before starting work, the compressed air ejector must be disconnected from the compressed air supply.Starting torque for the thread connections are to be taken from the corresponding DIN-Norm.

Caution

We advise to exchange all sealings at repair work.

Disassembly of the compressed air ejector:- Take off cable plug at the solenoid valve of the compressed air ejector.- Loosen the exhaust and compressed air pipe.- Loosen the assembling screws of the compressed air ejector and remove the compressed air ejectorAssembly takes place in reversed order.

2.2 Disassembly and assembly of the jet system- Fix the compressed air ejector and turn out the long nibble.- Pull out the mixing jet of the casing- Take out the driving jet of the casing.Assembly takes place in reversed order.

Caution

The long nipple has to be screwed on the casing powerful. The check nut may not to be twisted.The long nipplemust be fitted with a bolt protection medium (e.g. Loctite).

2.3 Disassembly and assembly of the shut-off valve- Loosen the pressure switch casing at the compressed air ejector

Pressure switch casing is spring pressurized.

- Take out the compression spring and loosen the safety nut at the spring seating. Use the safety nut at thepiston (jet side) for supporting.

- Take out spring seating, guide ring and valve seling of the compressed air ejektor.- Take out the Piston rod with mounted piston.Assembly takes place in reversed order.

Caution

When assembling the piston the gasket is to be pressed via compressed air supply by a similar formed tool.
