Merlin


1. IntroductionThe Merlin is an integrated eductor based excavation system which isdesigned to pump mud, sand, gravel, drill cuttings or shale without risk ofblockage.

A heavy-duty cylinder operates a valve to reverse the flow at the nozzle toeject any object which may be causing an obstruction. A second cylinderoperates a bypass valve to provide a powerful direct jet to break up heavyand cohesive seabed mud and sand prior to excavation.

The pump may be configured to an intermediate position allowing combineduse of suction and jettings. Both the impeller and eductor have been optimisedfor use on Work-class ROVs.

3. InstallationWarning

Do not power the Merlin pump or hydraulic valve actuators until allhoses are properly connected.

If powering or testing on deck it is important to ensure that allappropriate safety measures are in place to prevent injury.

3.1. MechanicalThe pump may be mounted in any orientation on the vehicle. There are fourmounting points with 10mm clearance through holes

Not to scale, dimensions in mm.

the pump should not be mounted using the motor or hose nozzles asattachment points. Case bolts should not be used.

3.2. Water Hoses

Hose TypesFor correct hose sizes refer to Chapter 2, Specification.

The recommended hose type is: heavy duty nylon spiral reinforced.

This hose type is usually semi-transparent which assists visual inspection fordamage and blockages. Since it is all plastic it is light in water.

Both suction and discharge hoses should have a smooth internal bore withspiral reinforcement.

Installation Merlin


Layflat style hoses are not recommended for discharge.

Fittings

Use standard heavy-duty worm drive clips. Use of heavy-duty two bolt clampswill result in damage to the hose connections on the pump unit.

Clean Suction Intake Screen

It is recommended that a Tritech International Ltd supplied suction straineris used with the pump. If using another strainer it must meet the followingspecifications:

• Maximum hole size: square mesh of 4mm aperture or circular perforationsof 6mm diameter.

• Minimum total free flow area: 0.025m²

The pump should not be operated in any circumstances without a suctionscreen.

Dredge Suction Nozzle

Suction nozzles should be designed with a nozzle cross-section area ofapproximately 80000mm²

Smaller nozzles may be used but material removal rates will be reduced.Larger nozzles are of no benefit and will reduce performance.

A nozzle guard should be fitted that will pass a maximum of a 60mm diametersphere or 50mm sided cube. The pump can pass single objects of a largersize, but if it takes in a stream of objects then blockages can occur.

Jet Nozzle

The recommended sizes are 12 to 18mm diameter or an equivalent area.

The optimum size will need to be determined by trial because the wateroutput from the power pump will vary depending on the oil pressure and flowavailable from the ROV hydraulic system.

Installation Merlin


3.3. Hydraulics

Oil

The pump should be operated using a premium grade mineral basedhydraulic oil of ISO VG 22 to 23

Filtration

The hydraulic system filtration must be to a minimum of 10μm absolutestandard. A 10μm nominal standard is regarded as inadequate.

The recommended filtration is UN elements produced by Pall IndustrialHydraulics Ltd. or equivalent products.

Hook-up

Figure 3.1. Hydraulic Hook-up Orientation

Installation Merlin


The pump is configured for correct rotation when the hydraulic supply isconnected to the "A" port of the Volvo motor and the return line to the "B" port.

Figure 3.2. Motor viewed when fitted to Merlin with hydraulic fittingsdownwards

The drain connection from the motor back to the tank is required to be aminimum of ⅜ inch bore. The drain line should return straight to the tankwithout restriction. It is possible to connect the drain line back to a larger boredrain manifold, which has been correctly sized to accommodate all drainsattached to it.

Warning

The drain line should not be connected to any return flow lines.

Warning

Self-sealing quick disconnect connectors should not be used onthe drain line. Such connectors, if incorrectly fitted, may resultin pressurisation of the motor casing which could fail explosivelyunder pressure resulting in significant risk of personal injury.

Installation Merlin


Required Hydraulic Flow

For the Volvo F11-19 motor the vehicle hydraulic system should be capableof supplying a flow rates and pressure detailed in Chapter 2, Specification.

Achieving the required flow in an unloaded condition is no guarantee that thesupply can actually be met in working conditions.

It is recommended that the installation be checked using a hydraulic flowmeter equipped with a loading valve which can simulate the motor runningunder load.

In order to avoid pressure losses a minimum of ½ inch bore pipes or hosesare used on the flow and return lines (¾ inch or larger is recommended).

Warning

Under no circumstances should the flow be allowed to exceed the25 litres per minute (while testing in air).

Exceeding this pressure when operating in air (when there is noback-pressure on the pump) may cause a catastrophic failure ofthe pump and result in personal injury.

3.4. Retro Flush Valve and Jet Bypass ValveTo independent controls are required, one for the jetting actuator and one forthe retro valve.

The actuators can be connected to any standard three-position 4-waysolenoid valve. Pilot operated check valves is preferred but a closed centrespool valve is adequate. If either actuator is not used then they must be filledwith oil and securely capped. This is particularly important for the jet bypassvalve, which could easily be pulled open severely reducing efficiency.

The supply pressure for reliable operation is 120 bar.

The actuator connection fittings are: No. 4 JIC male

The jet valve should be powered shut when jetting is not required.

3.5. Seal CompensatorThe Merlin has a separately compensated seal void which is grease filled andhas its own miniature compensator.

Installation Merlin


On installation the compensator level should be checked. The stem has anindicator groove showing when it is full. If necessary gently apply greasevia the grease nipple provided until the groove just shows or the grease isexpelled from the overflow.

Caution

Pump the grease very slowly to avoid building up excessivepressure in front of the motor face.

Merlin


4. Principles of Operation

4.1. Suction OperationThe Merlin pump is based on the principles of the annular eductor pump. Ithas a monoblock configuration in which the eductor pump and power pumpare contained within a common body.

The power for the eductor section of the pump is provided by a stream ofclean water driven by the centrifugal impeller section.

Clean water is drawn into the inlet, passes through the impeller of the powerpump and is then injected into the main suction stream via the annular eductornozzle.

The main suction stream can convey heavy contamination of sand, mud,gravel and drilling debris.

The pump has a retro flush valve just behind the eductor. When this is closed(operating cylinder extended) the power fluid is then directed to the suctionnozzle. This feature can be used to clear a blocked suction nozzle or tocomplete a deburial operation by removing the sand and mud from aroundan object.

The optimum performance will be obtained with the nozzle pushed deep intothe debris and agitated gently. Where a great deal of debris is encountered itwill be necessary to keep withdrawing the nozzle.

4.2. Jetting OperationThe body of the pump contains a jetting valve. The purpose of the valve is toprovide water to the jetting outlet. The valve may be configured to maintainsuction during jetting operations. For normal dredging operations the jet valveshould be kept shut.

Note

The Merlin can be setup to restrict flow through the jetting valve. Toimplement this place the M8 x 16 SKT CAP (item 9) in one of thethree holes in the housing mounting plate (item 1 - see Appendix B,Merlin Assembly).

• Hole 1 gives : ‘low jetting, high flow’

• Hole 2 gives : ‘medium jetting, medium flow’

Principles of Operation Merlin


• Hole 3 gives : ‘high jetting, low flow’

Merlin


5. MaintenanceWarning

Do not power the pump or hydraulic valve actuators until all hosesare properly connected to the pump.

There is a serious risk of injury to fingers if inserted into either thepower water intake or the pump delivery port.

If undertaking any testing operations suitable guards and othersafety measures must be in place.

5.1. Basic Procedures

Hydraulic Motor Shaft Seals

The pumps are fitted with either an 'H' (red) or 'V' (brown) type seal. The typeV is the standard seal and is high pressure, high temperature.

Replacement of seals with anything other than a genuine seal (or TritechInternational Ltd supplied seal) will invalidate the warranty.

Pre-dive

Visual check for external damage.

Check hoses are secure.

Check mountings are secure.

Check clean water suction strainer is in place and clear.

Check the mini compensator for the seal housing is extended. If not applyone or two strokes with a grease gun until the compensator relieves.

Storage

Note

If the vehicle will be inactive for more than 48 hours run a a freshwater hose into the clean water suction strainer for a few minutesand then spin the hydraulic motor for about 15 seconds (taking carenot to over-speed).

Maintenance Merlin


If the pump is removed from the vehicle, then the hydraulic ports should beblanked off with metal caps and the unit washed out with fresh water.

Leave the actuator valves in their retracted position.

Visually inspect the leading edges of the power pump impeller for damageand erosion.

Up to four blades may have leading edge damage of 5mm width and 4mmdepth before replacement becomes essential.

If the majority of leading edges are eroded more than 3.5mm back from thebore of the inlet nozzle then consideration should be give to replacing theimpeller.

5.2. Tools RequiredThe following tools are required to work on the pump:

• 22mm open ended spanner

• 13mm open ended spanner

• 10mm Allen key

• 8mm Allen key

• 6mm Allen key

• 5mm Allen key

• 2.5mm Allen key

• Dead blow hammer

• Loctite - "Studlock" for reassembly

For detailed assembly procedures refer to Appendix B, Merlin Assembly.

Merlin


6. TroubleshootingIf the Merlin is experiencing poor performance check the following:

• Check that the clean water suction strainer is clear and that there are noblockages in the hose.

• Check that the retro-flush valve is opening fully.

• Check that the jet valve is seating properly.

• Check that the suction hose reinforcement is intact and that there is no signof the hose collapsing under suction.

• Check that the discharge hose is not damaged or kinked.

• Remove the clean water suction hose from the pump and check that theface of the impeller is not obstructed by material like rope fibre or shredsof plastic.

• Check that the hydraulic motor runs freely without excessive noise orvibration.

• Check that the hydraulic flow meets specification.
