FAM 15/30 ATEX Description of function



Description of function

Switch on the FAM at the main switch. After the "Start delay" switch is activated, the inlet valve opens and the vacuum pump builds up the necessary vacuum. This vacuum causes the fluid which is to be purified to be sucked into the vacuum chamber.

The fluid to be cleaned trickles downward through special filling materials. These filling materials multiply the surface in the vacuum chamber and make it possible to form a fine fluid film.

The fluid collects in the bottom of the vacuum chamber up to the level switch [02]. Then the inlet valve closes, and the evacuation pump conveys the fluid through the fluid filter to the outlet.

The filling level in the vacuum chamber drops down to the level switch [01]. Once the level [01] is reached, the 2/2 directional control valve opens, and fluid passes from the inlet through the suction strainer in vacuum chamber until the level switch [02] is reached. The 2/2 directional valve closes and the procedure begins again.

The vacuum in the vacuum chamber sucks atmospheric air out through the air filter. This air flows down into the vacuum chamber and is sucked out by the vacuum pump. By virtue of this flow of air, the air picks up the humidity of the fluid.

The monitoring of the vacuum pump is limited to the pressure and the temperature. The oil fill level in the vacuum pump is to be monitored by daily visual inspection.

The vacuum in the vacuum chamber is set with the throttle valve (vacuum setting).

The evacuation pump is protected against dry running by the fill level limit switch in the vacuum chamber. The fill level limit switch switches the electric motor of the evacuation pump off when the vacuum chamber has been emptied.

When the "Stop overrun" switch has been pressed, the inlet valve closes and the evacuation pump pumps the vacuum chamber empty. As soon as the light H2 goes out, the FAM can be switched off via the emergency-off switch.

When the emergency-off switch has been put into OFF position, the vacuum pump and evacuation pump are switched off. The inlet valve closes under spring force.

OUT

The FAM is connected with suction and pressure lines to the tank and cleans the medium to be found there in continuous operation.

Transfer by pumping

IN

OUT

The FAM is connected to the contaminated oil tank by means of a suction line and pumps the fluid into the clean oil tank.

However, better purification results are achieved with bypass purification. Therefore, the FAM should be operated after pumping in the bypass flow.

To avoid overfilling the purified oil tank, permanently monitor the oil level.

FAM 15/30 ATEX Explosion protection as per ATEX 95



Explosion protection as per ATEX 95

The water extraction units of the FluidAqua Mobile FAM-ATEX series satisfy all the requirements of the new EU directive 94/9/EC, ATEX 95 applicable to areas in which potentially explosive gas mixtures are likely to occur.

The designation of the explosion-proof ATEX-compliant FAM is:

II 2G IIB+H2 T4 (+10°C<Ta<40°C)

II 2G IIB+H2 160°C (+10°C<Ta<40°C)

This means that the FAM may be used only in accordance with:

Equipment group II Potentially explosive atmospheres in which vapors or gas/air mixtures are likely to occur.

Equipment category 2G Equipment providing for a standard degree of safety.

Designated for cases in which atmospheres posing an explosion hazard can be expected to occur very rarely and, if so, only briefly.

Explosion hazard subgroup

IIB+H2 Typical gases: Town gas, acrylonitrile, ethylene, ethylene oxide, ethylene glycol, hydrogen sulfide, ammonia, methane, ethane, propane, ethyl alcohol, cyclohexane, n-butane, n-hexane and hydrogen

Ensure that vapors, gases or mists occurring at the place of operation belong to explosion groups IIA to IIB.

Temperature class T4 Maximum permissible surface temperature: 135°C

FAM 15/30 ATEX Setting up the FAM



Setting up the FAM

Observe the following points when setting up the FAM:

Place the unit on a horizontal and level surface. Special mounting is not required.

Mobile version only - Lock the immobilization brakes on the wheels to avoid unintended movement/rolling away of the unit.

Position the FAM in the immediate vicinity of the tank to be cleaned. Observe the maximum permitted suction pressure. See page Fehler! Textmarke nicht definiert..

Observe the ambient temperature on the type label of the FAM.

Ensure that the main switch is free and accessible at all times.

Keep an area of at least 0.8 m around the FAM free for maintenance purposes.

Make sure there is sufficient ventilation around the area where the FAM is set up.

CAUTION Outlet air of the vacuum pump

Hazardous to health

► Always make sure there is sufficient ventilation in the surrounding area of the FAM.

Air coming out of the vacuum pump can contain particles of vacuum pump oil and/or the fluid.

Depending on the composition of the oil and the composition of the gas, there is a danger of damage to health if the emergent gas is inhaled over an extended period of time.

FAM 15/30 ATEX Connecting the FAM



Connecting the FAM

All hoses on the FAM must be sufficiently conductive to properly discharge electrostatic charge buildup.

If hoses are used, the ohmic resistance between the fittings—in this case between the FAM and the tank—may not exceed a limit value depending on the respective hose type.

Marking the hose with the symbol "M":

Limit value ≤102

Marking the hose with the symbol "": Limit value ≤106

The hose connection must ensure a highly conductive transition between the hose and FAM tube, as well as between the hose and tank tube.

If this is not the case, all conducting parts (such as the metal mouth piece at the end of the hose) are to be grounded separately.

Connecting conductive hoses with fittings to hose tubes requires marking and checking per DIN EN 12 115.

Connect the ground clamp of the FAM to a suitable grounding source nearby. The grounding lead is 3 m long.




Notes on pipes and hoses

In order to keep the pressure loss as low as possible, use as few threaded connections as possible.

The pressure differential in a hydraulic line (P(line)) depends on the following:

Flow rate

kinematic viscosity

Pipe dimensions

Fluid density

The pressure loss in straight pipes (P(line)) can be calculated as follows:

Δp ~ 6,8 * L / d4 * Q * V * D Δp = Pressure differential in [bar]

L = pipe length [m]

d = internal pipe diameter [mm]

Q = Flow rate [l/min]

V = Kinematic viscosity [mm²/s]

D = Density [kg/dm³] Mineral oil based hydraulic fluid has a density of ~ 0.9 kg/dm³.

This applies to straight pipe runs and hydraulic oils. Additional threaded connections and pipe bends increase the pressure differential.

Keep the height difference between the pump and the oil level in the tank as minimal as possible.

Hoses must be suitable for suction pressures of at least -0.5 bar.

Avoid constrictions in connecting pipelines because they reduce output and increase the risk of cavitation.

The nominal size of the connected hoses/piping must be at least as large as the inlet port sizes in order to prevent an excessively high negative suction pressure.




Connecting the suction port

NOTICE

Overpressure at the suction port connection

The unit is damaged

► The pressure at suction port IN must be in the range from -0.25 to +2 bar.

NOTICE

Contamination too high

The unit is damaged

► Do not prime directly at the bottom of the tank

► Do not prime in the sump

The greatest contamination is found on the bottom of the tank. All impurities and other particles are deposited on the bottom of the tank.

Make the suction-side connection with a flexible hose that is resistant to negative pressure or with pipelines. The nominal size of the connecting lines must be at least as large as the cross-section of the unit in order to prevent excessively high pressure loss.

The suction port must be arranged so that it is always below the oil level.

Connecting the pressure port / return-flow line

NOTICE

Return port connection OUT closed off

The unit is damaged

► Close the return port connection OUT

To avoid a concentration of air in the medium, the return-flow line must always be located below the oil level.




Electrical connection of the FAM

DANGER Electric shock

Danger of fatal injury

► Any work involving the electrical system may only be done by a properly trained, certified electrician.

The voltage and frequency information on the rating plate must coincide with the voltage supply present.

If a plug is present on the FAM or if a plug is mounted, then the FAM is to be operated from a correspondingly fused socket.

The rotating field of the connection socket must be clockwise. If this is not the case, then the phases can be rotated in the 16A / 32 A connection plug with the aid of the phase changing switch in the plug. For the 63A version, the two phases must be switched on the terminal block S0 (e.g. L1 and L2).

A phase sequence relay checks the correct phase sequence after switch-on. In the event of an incorrect phase sequence, error message no. 29 is shown on the control panel.

Prior to start up, ground the FAM using equipotential bonding.

Prior to starting up the FAM, connect the ground bond to the FAM and the tank to be cleaned.

Check the connection between the tank, the FAM and the ground potential for good conductivity.




Preparing the rotary vane vacuum pump

As a basic rule, the rotary vane vacuum pump is not filled with oil at the time the FAM is delivered. A sufficient amount of vacuum pump oil for the initial filling is included in the scope of delivery.

NOTICE

Operation without vacuum pump oil

The rotary vane vacuum pump will be destroyed.

► The rotary vane vacuum pump requires oil as its operating medium.

► Check the oil level before start-up, topping up with vacuum pump oil VE101 if necessary.

Filling the vacuum pump

Max.

Min.

[a]

[c]

[b]

To fill the vacuum pump, open the fill plug [a]. Add oil until the level comes up to the MAX mark on the oil level glass [b].

Check the oil level daily. When the fill level gets down to the MIN mark, add oil.

The oil fill quantity for the initial filling is ~ 2.0 liters. The oil fill quantity between the MIN and MAX marks is ~ 0.45 liters.

The vacuum pump is certified for operation with synthetic oil "Leybold LVO 210". If a different oil is used, the EC and ATEX certificates are voided.

This vacuum pump oil is available from HYDAC under the following part no.:

DESCRIPTION Packaging Part no.:

Compressor oil - Leybold LVO 210 1 liters 3765250


Filling the seal chamber of the evacuation pump

Before initial commissioning, the seal chamber of the evacuation pump must be filled with the sealing medium ISO VG 10 ... ISO VG 100.

For topping off, use the medium to be purified having a viscosity of ISO VG 10 … VG 100.

This is needed in order to prevent dry running of the shaft seals.

Dry running of the pump would result in premature wear and tear and impermissible heating at the sealing lip or dust lip.

This also prevents the ingress of air into the fluid.

Check the fill level of the reservoir (1) at least once a week and top off as needed.

FAM 15/30 ATEX Starting up the FAM



Starting up the FAM

After all connections are made and the preparations for commissioning are complete, switch on the FAM at the main switch. For the lamp test, all lamps light up briefly.

Then the FAM goes to malfunction "[H15] V-pump pressure"; the malfunction light [S3] "Malfunction" blinks. This fault message results from the switch position of the "Siguard" (electric circuit diagram = A5) in the control cabinet and is eliminated by pressing the button [S1] "Start delay" or the button [S3] "Malfunction".

The system now begins with the starting phase. The vacuum pump starts up, the inlet valve opens, and the vacuum chamber is filled. When the vacuum chamber is filled to filling level [02], the evacuation pump is started up and the starting phase is finished. The purification operation runs. This is shown by the lighting up of the operating status lamp "FAM operation (H4)".

Setting the vacuum pressure

Now regulate the vacuum pressure in the vacuum chamber with the throttle valve underneath the vacuum pressure display, depending on the operating viscosity.

Oil Operating viscosity Pressure setting (absolute pressure)

Hydraulic oil 50 mm²/s 250 mbar / 25 kPa

Lubricant 300 mm²/s 250 - 500 mbar / 52 - 50 kPa (depending on foaming behavior)




Venting the filter housing

WARNING Hot fluid

Risk of burns

► Note that hot fluid may exit during bleeding.

fluid.

(2) Open the drain fitting, and collect the escaping fluid in the tray.

Once the housing has been completely drained, close the drain fitting.

3. Screw in the air bleed screw (x) by hand in a clockwise direction, and tighten it firmly using a 10 mm Allen wrench.




4. Release the housing tensioning clamps (1), and remove them.

Remove the cover (a).

Remove the intermediate piece (b).

5. Turn the element locking cap on the top filter element 90° in the counterclockwise direction (1), and remove the locking cap (2).




6. Turn all filter elements 90° in a counterclockwise direction, and remove them.

7.

Dispose of the old filter elements in an environmentally-friendly manner.

8. Clean the inside of the filter housing of coarse dirt.

Check the O-rings on the filter housing for damage. Replace them if necessary.




9. Insert the filter element into the bayonet fitting (1), and lock it in place by turning each individual filter element 90° in the clockwise direction (2).

10. Place the element locking cap on the upper filter

element (1).

Turn the locking cap 90° in the clockwise direction to lock it in place.

No element locking cap = no filtration.




11. Put the intermediate piece (b) on the lower section (c).

Mount the lower housing tensioning clamp (1), and tighten it with a torque of 20 Nm. Secure using the lock nut.

Put the cover (a) on the intermediate piece (b).
