Preface

These installation guidelines

• are part of the overall documentation compiled for the separator.

• describe the procedures for constructing, manufacturing and design-ing separators.

• contain fundamental instructions for installing separator installations.

• contain general guidelines for separator installations.

These guidelines specify the minimum specifications for designing and constructing frames, tanks, piping and the electrical installation.

Putting together and installing the installation components must be carried out in accordance with the order-specific documents:

• Installation diagram and equipment list

• Dimensioned drawing (notes on required space for operating and servicing, minimum clearance from walls/pillars or other machines)

We reserve the right to carry out technical modifications on the separator!

Attention must be paid to the operating, maintenance and mounting instruction manuals of all units and fittings.

For your safety

• Take special care when carrying out operations marked with this symbol -otherwise danger to life!

• Strictly adhere to instructions marked with this symbol.

This avoids damage to the separator and other equipment.

Note: • This symbol is not a safety precaution but rather a reference to infor-mation which help to better understand the separator or plant compo-nents and the processes.

• Use only genuine spare parts from GEA Westfalia Separator. The origi-nal spare parts are listed in the spare parts catalog.

The use of non-genuine parts leads to:

– safety risks,

– reduced durability of these parts,

– reduced availability of the separator and

– increased service requirement.

If a safety risk occurs when using non-original spare parts, this may have legal consequences for the responsible persons. In such cases, GEA Westfalia Separator accepts no liability or warranty claims.

1.1 Safety precautions

• Pay special attention to the safety precautions contained in the overall documentation compiled for the separator!

1.2 Material

• The specified material must conform to the standards set out in these installa-tion guidelines as a minimum requirement.

• All materials used must be new and from the same series.

1.3 Installation

Fig. 1 Installation example

1 Separator: 7 Solids tank venting 2 Separator foundation 8 Crane 3 Control unit 9 Cleaning table 4 Control cabinet 10 Aeration 5 Preheater 11 Venting 6 Solids tank

• The applicable regulations and standards of classification societies or other authorised bodies must be observed.

• All lubricating points and the gear / drive housing of the separator must be easily accessible without having to remove pipes or gratings.

• All operating elements must be within comfortable reach of the operator and at a suitable height.

• Operating elements must not be mounted higher than 1800 mm above the working platform.

• All units must be arranged so that they do not cramp the working area and so that they can be safely serviced and operated.

2058-9601-020 / 0211 9

• All fixed piping and fittings must be safely supported to reduce vibrations and movement to a minimum.

• Contact points or supports must be fitted so that the pipes are able to move with changing temperatures without creating tension in the pipes.

• Pipes and pipe connections must be accessible for maintenance.

• Pipes must not be used for supporting distributors or appliances.

• These regulations and standards do not apply to small purpose-built parts whose durability, accessibility and operation are not influenced. They must be fitted in accordance with the manufacturer's recommendations.

• No galvanized parts may be fitted in product-carrying lines (e.g. heavy oil, diesel oil, steam lines and thermal oil lines). This does not apply if type-tested pipe joints are fitted in pipe trace heating systems.

• Y-strainers should preferably be fitted horizontally with the strainer insert pointing downwards or to the side (turned through 90°).

If this is not possible for space reasons, the dirt pan can be fitted vertically with a throughflow from top to bottom. In this case, ensure that the strainer can be dismantled.

10 2058-9601-020 / 0211

1.4 Storage

• Parts may be stored only in original GEA Westfalia Separator transport pack-aging.

• A storage time of more than 12 months is only possible after consulting the manufacturer.

• The storage site should be a closed, dry room.

• The storage temperature must not be below 5°C (41 F) and must not exceed 50 °C (122 °F).

IMPORTANT:

• Outdoor exposure is not admissible!

Pay attention to the following points on storage and transport packaging.

• Handle fragile goods with care!

• Protect the goods against moisture and humidity.

• Protect the goods against heat!

• Pay attention when erecting the goods.

1.4.1 Installation of controls

• Select the installation site so that

– the control unit is not exposed to dust and aggressive atmosphere.

– the control unit is not installed in an excessively humid environment or damp area.

– the sun cannot shine on the control panel or displays making operation and observation more difficult.

– heating up of the control unit is avoided.

• Where appropriate, check screw-type and plug-type connectors for secure contact.

2058-9601-020 / 0211 11

• Connect thermostatically controlled cabinet heating to external voltage and switch it on.

• The control cabinet heating must switch on before the temperature drops be-low the dew point.

• Bedewing can occur during the night which is not good for electronic appara-tus.

• Check that the line voltage and frequency conform to the connection data of the control unit (see nameplate).

• Pay attention to admissible installation and operating data:

Voltage fluctuations +/- 10 % of the line voltage Frequency fluctuations +/- 2 % of the line voltage Ambient temperatures + 5 to + 45 °C (41 to 113 °F) Atmospheric humidity max. 50 % at 40 °C (104 °F) max. 90 % at 20 °C (68 °F) Installation height above sea level up to 1000 m Transport temperatures – 25 to + 55 °C (–13 to 131 °F)

Improper installation and operation discharges the supplier from the warranty obligation.

1.6 Preservation measures on site

After installation until commissioning

• All parts such as tools, spare parts and bowl must be stored in the original packaging in a suitable place until commissioning.

• The parts must be stored at 5 to 50 °C (41 - 122 °F) in dry, weatherproof rooms to prevent the packaging from getting damaged.

• The spindle and gear/drive chamber are lubricated at the factory which pro-tects them for a period of 12 months.

• In the case of a storage and standstill period of longer than 12 months, the time-dependent maintenance intervals specified in the instruction manual must be adhered to before putting the machine back into operation.

• After this time (12 months) has expired, it must be checked at 12 monthly in-tervals that all bearings and the spindle have sufficient lubrication.

• Oil to be used:

– Shell oil S.7294 (SAE 30/SAE 50) for bearings and spindle,

– roller bearing grease for the spindle cap.

2.3 Required hoist specifications for separators

Flat belt separators

• The hoist must be travel-type or swivel-type.

• The hoist must be arranged so as to enable the following:

– Vertical fitting and removal of the bowl (see section 2.1.1, table - dimension

F).

– Horizontal removal and fitting of the drive motor (see section 2.1.1, table -dimension X).

2.4 Ventilating the separator room

• Pay attention to the correct arrangement of the air feed and discharge lines so that

– the separator room is efficiently ventilated,

– the admissible room temperature – normally max. 45 °C (113 °F) – is not exceeded.

The rating of the electrical apparatus is critical in this respect.

If the admissible temperatures are exceeded, additional measures must be taken. Maintenance intervals and maintenance measures may have to be ad-justed accordingly.

2.9 Pipelines on the separator

The following sections describe the general set-up of the piping system in the separator installation:

2.9.1 Product line

• Product lines must be laid

– in accordance with the guidelines of GEA Westfalia Separator or

– in accordance with the requirements of the classification societies.

• Use only genuine parts from GEA Westfalia Separator!

• The lines must be flushed before commissioning to protect the valves and units.

• The following lines must have no rigid connection with the separator in order to prevent vibrations:

– Product feed and discharge

– Water connection

– Solids discharge

– Dirty water discharge

– Frame drain

• This can be realised by means of hoses or compensators, whereby there are special requirements for shockproof separators.

• Hose pipes must be laid so that they cannot be twisted, kinked, clamped or rubbed.

• Use only hoses from GEA Westfalia Separator!

2.9.2 Operating, filling and displacement water lines

5.1 General

• Pay special attention to section 1.3!

• The suction lines should be as short as possible to avoid pressure losses.

• The pipes must be installed with adequate clearance from the electronic parts.

• Water pockets must be avoided! (water must be able to flow off freely).

• When different products are run through the same separator, it must be en-sured that the corresponding product lines cannot be interchanged.

5.2 Pipe cross-sections

• All pipes, valves, fittings and instruments must be laid so that an insulation of

40 mm is possible.

• Dimensioning of the pipes is specified on the respective P&ID.

• The pipes can be selected with the aid of the following diagram. The specifi-cations on the P&IDs have priority!

• Pipe resistances must be kept as low as possible.

• Taking into account the total pressure losses, the flow velocities must be

– between 0.5 m/s and < 1 m/s in suction lines,

– between 1 m/s and 3 m/s in pressure lines.

5.3 Functional description

The liquid is discharged from the separator by means of a pumping device, in the following referred to as centripetal pump. At small capacities, the discharge can be without pressure; in the case of larger capacities the centripetal pump generates the required pressure to convey the liquid out of the separator through the downstream lines by immersing more deeply into the liquid.

The pressure values can differ significantly. The following rule applies: The val-ues are lower on small separators than on large separators.

Further influencing factors are capacity, system resistances (valve position, tank position), product properties and process specifications.

5.4 Information on pressure monitoring

When the liquid is discharged from the separator under pressure, the operator knows that the separator bowl is hydraulically closed.

A discharge pressure adjusts given a constant capacity or it is adjusted to the desired value by throttling in the discharge.

In the standard application, the pressure sensor responds to falling discharge pressure, an alarm is triggered via the control system. The control system can also evaluate rising pressure and trigger an alarm.

Generally, the discharge pressure is set to 0.1 – 0.2 MPa. The pressure level can deviate from this when separator size, capacity, product properties and process specifications require. (for further information, see the order-specific documentation)

2058-9601-020 / 0211 41

A change in the discharge pressure may be caused by the following factors:

• Change in feed capacity

• Change in product data such as temperature, density, viscosity

• Change in discharge resistance

• Leakage at the separator bowl This represents important information for the operator.

1 Settling tank 2 Service tank

• When separating heavy oil, the return line of the 3/2-way valve must be led into the settling tank 1.

5.6 Maximum suction head

• The suction head of the feed pump (gear pump) is max. 0.04 Mpa.

• The suction head of the feed pump (screw pump) is max. 0.05 MPa.

• The viscosity of the oil to be conveyed must be kept < 1 000 cSt, if necessary by adequate pre-heating and trace heating.

• When dimensioning the suction line, it must be ensured that the total pressure loss in the pipe does not exceed the maximum suction head of the pump.

• The maximum feed pressure in the suction line must not exceed 0.05 MPa.

5.6.1 Pressure line

• The pressure head of the feed pump is set to approx. 0.3 MPa.

• The pressure line from the feed pump via the pre-set valve, the pre-heater and the 3/2-way valve to the separator must be kept as short as possible.

• When dimensioning the pressure line, it must be ensured that the total pres-sure loss in the pipes does not exceed the maximum pressure head of the pump.

44 2058-9601-020 / 0211

5.6.2 Pre-filter

• The pre-filters are fitted in the suction line of the feed pump to protect it from coarse impurities.

• During the installation, special attention must be paid to the operability.

• Use only strainers with a mesh width of the strainer insert of 1 to 1.25 mm.

• Pay special attention to section 1.3!

Fig. 38

• Use only pre-strainers with a mesh width of the strainer insert of 0.63 mm.

Fig. 39

5.7 Feed pump

To prevent the pre-heater from overheating,

• a pump post-running time must be programmed for pump units and product pre-heating.

5.8 Oil pre-heater

• It must be installed so that there is no heat dissipation to the control cabinet.

To prevent a risk of accidents when venting due to discharging hot va-pours and liquids,

• the discharge lines from vent valves must be laid at least to floor plate height.

• Discharge lines of safety valves must be laid so that there is no danger of accident when the valve responds due to discharging liquid.

• The discharge line must be laid so that it can always be observed. It must not be concealed by pipes, valves or other units!

2058-9601-020 / 0211 45

• Steam traps

– must be fitted horizontally between two unions.

– should not be insulated to assure correct functioning.

– must be installed so that no condensate accumulation can occur on the pre-heaters.

7.2 Electro-magnetically compatible installation

• The control cabinet is designed to be electro-magnetically compatible.

• The following must be taken into account with electro-magnetically compatible installations:

– Earthing straps

– Voltage equalization

– Screening lines

– Separate line routing

– Use of erase elements in case of inductance.

In the case of HFO series operation, proceed in accordance with the following wiring diagram:

• Use only data cable UNITRONIC-BUS-FD P L2/F.I.P (1 x 2 x 0.25 mm² +

Screen).

• Do not lay data cables directly next to load cables as this can cause prob-lems with electromagnetic compatibility.

• Pay attention to the different software status on the C7 units:

– 1. unit has the MPI addresses 1 / 2

– 2. unit has the MPI addresses 3 / 4

– 3. unit has the MPI addresses 5 / 6

• Faulty or broken cable connections are displayed with error code no. 551.

• Check all connections.
