7 Operation

7.1 Functional description of the automatic filter

The automatic filter is used to filter particles from media in order to protect the downstream parts of the plant.

The automatic filter is used to protect the bearings, journals and shafts in the motor from damaging impurities in the oil.

The automatic filter is suitable for filtering media (oils) with an operating pressure of at least 3 bar.

The automatic filter works with permanent medium backflushing. The backflushed fluid is fed back into the circulation tank or oil tank.

The filter elements are cleaned automatically so that the plant does not have to be switched off for cleaning.

The automatic filter works as a continuous flushing device and does not require any external energy for actuation of the backflushing device.

The filter can be installed to stand or be flanged (customer's own fastening). 7.1.1 Filter housing

The filter housing contains all the pipe connections, the vent, drain hole and the connection points for the pressure monitoring system.

The cover is screwed to the housing.

The backflushing device is integrated into the housing.

The function of the backflushing device can be checked through an inspection glass in the cover.

7.1.2 Differential pressure monitoring (optional)

The differential pressure monitoring system measures the differential pressure between the filter inlet and filter outlet. As the contamination increases, the differential pressure in the filter also increases.

The differential pressure monitoring system indicates the differential pressure optically and/or provides electrical signals for further processing.

(26)

26 / 58 Operating instructions 6.48 Betriebsanleitung 6.48 CAUTION!

Insufficient filter performance may cause damage to downstream components

Reduced filter performance over longer periods of operation can cause damage to downstream components.

• Clean the filter immediately if a differential pressure signal is active.

• Only ever operate the filter in an emergency if an alarm is active. The filter (filter candles and protective sieve) must be cleaned immediately.

NOTE

• You will find more detailed information on the differential pressure monitoring system in the appendix of these operating instructions or in the manufacturer's documentation.

• The control line for the differential pressure monitoring system is fitted with shut-off valves (e.g. ball valves).

7.1.3 Backflushing device

The backflushing device which is in constant operation and comprises a turbine, worm gear pair, flushing arms and optical inspection facility (inspection glass and rotary indicator), cleans the filter candles during operation.

An optional nozzle on the flushing oil outlet regulates the backflushing effect. The flow energy of the filter medium drives the backflushing device.

(27)

(28)

bottom end of the filter candles. A partial flow is fed via the connecting pipe to the top end of the filter candles.

This means that the medium flows through the filter candles at both ends, from the inside to the outside, and in the process larger particles of dirt are held back on the inside of the filter candles.

(29)

(30)

speed of the turbine is reduced to the lower speed required to rotate the flushing arms by the worm gear pair and cog wheel.

The function of the backflushing system can be checked using the inspection glass and rotary indicator.

The individual filter candles are connected alternately to the atmosphere and the flushing bush and nozzle (optional) by the continuously rotating flushing arms. The pressure gradient (operating pressure to the atmosphere) which this produces has a particularly effective cleaning effect on the filter candles.

This connection is established alternately by the bottom and top flushing arm. In each case, the opposite side of the filter candles is closed at the same time. This also changes the direction of flow of the medium through the filter candle which in turn increases the cleaning effect.

The turbulent flow in the longitudinal direction of the filter candle (cross-flow backflushing) and the counterflow backflushing through the filter material which this creates, makes for a particularly enduring backflushing effect.

NOTE

Counterflow backflushing: The lower pressure on the inside of the filter candles during backflushing (connected with the atmosphere) and the higher pressure (operating pressure) outside the filter candles generate a counterflow through the filter material, from the filter's clean side via the filter's dirty side to the atmosphere.

The combination of cross-flow backflushing and counterflow backflushing causes the pressure loss in the filter to remain constant.

(31)

7.1.6 Overflow valves

1 Filter candle N1 Filter inlet

2 Overflow valve N2 Filter outlet

3 Differential pressure monitoring (optional)

N3 Flushing oil outlet

4 Protective sieve N2 N1 1 2 3 4 N3

(32)

overflow valves open automatically from a defined differential pressure level of 2 bar and above and the medium is partly filtered through the protective sieve only (emergency mode).

NOTE

The overflow valves are closed under normal operating conditions, even in start-up status at a low medium temperature.

CAUTION!

Insufficient filtration may cause damage to downstream components Operating the plant with the overflow valves open can cause damage to the downstream components due to the low filter capacity of the protective sieve. • Only operate the filter in an emergency for a short time with the overflow

valves open.

However, before this status occurs, a differential pressure signal (first contact) is issued by the optional differential pressure monitoring systems. The cause must then be localised and remedied.

If you do not pay attention to this signal, and the differential pressure continues to increase, the optional differential pressure monitoring system generates an alarm (second contact).

(34)

7.2.2 Functional description of the filter insert with filter candles

Filter inserts with filter candles are used for filtration. The medium flows through the individual filter candles from the inside to the outside and then through the protective sieve to the outside.

Particles of dirt in the flow are thus filtered off by the filter candles. The cleaned medium then exits the protective sieve and is fed back into the plant.

The filter insert comprises several filter candles arranged in parallel. The filter candles all have the same dimensions; they are interchangeable and can also be removed separately. The open ends of the filter candles are pressed into the bottom sieve plate and top sieve plate. The cover plate secures the filter candles to prevent them from sliding out upwards.

The type, design and number of filter candles used depends on the medium being filtered.

The protective sieve comprises a perforated plate and filter material on the inside. The perforated plate protects the filter material on the inside and the filter candles when installing and removing. The filter material on the inside filters the medium when the filter candles are damages or if the overflow valves are open due to heavily contaminated filter candles (emergency mode).

The dirty side is sealed off from the clean side by seals between the filter candle and the upper and lower sieve plate. The top and bottom sieve plates are connected by the connecting pipe to which they are screwed.

(35)

7.3 Commissioning

CAUTION!

Risk of damage to the filter from improper filling

If the filter is filled improperly, the filter elements may be damaged.

• Filling the filter against the indicated direction of flow of the filter elements is not permitted.

X Check whether all connections have been made properly.

X Open the shut-off valves in the control line to the differential pressure monitoring system (optional).

X Close the shut-off valve in the by-pass line (if available). X Completely open the shut-off valve at the filter outlet. CAUTION!

Risk of damage due to pressure surge in the lubricant circulation Pressure surges in the lubricant circulation can cause damage.

• Only partially open the shut-off valve at the filter inlet before switching on the plant and then open the shut-off valve slowly all the way whilst the plant is running.

X Partially open the shut-off valve at the filter inlet. X Switch on the plant.

X Slowly open the shut-off valve at the filter inlet all the way.

X Check the pressure downstream of the filter. If it is less than 2 bar, set the operating pressure to the required level by gradually closing the shut-off valve downstream of the filter.

X Check whether the rotary indicator is rotating (= backflushing system in operation) through the inspection glass in the cover.

CAUTION!

Insufficient filtration may cause damage to downstream components If an inadmissible increase in differential pressure occurs during commissioning and whilst the backflushing device is active, a signal is generated by the differential pressure monitoring system and the corresponding message is issued. This can typically be caused by initial contamination in new plants. Continuing operation can cause damage to downstream components.

• Take the filter out of service and clean all filter elements and if the overflow valves have opened, clean the protective sieve as well.

X The filter is ready for operation. DISPOSAL

(36)

36 / 58 Operating instructions 6.48 Betriebsanleitung 6.48 NOTE

When removing the filter and taking it out of service for longer periods, pay attention to the following points:

• Disconnect all connections from the filter. • The filter must be completely emptied. • The filter must be thoroughly cleaned.

• If necessary, seal the filter by applying a suitable anti-corrosive.

• The connection flange openings must be sealed with plastic (or similar) dummy plugs.

7.4.1 Disposal

DISPOSAL

When the filter or individual components and consumables are finally disposed of, make sure that they are disposed of in an environmentally friendly manner.

(37)

8 Maintenance and servicing

8.1 Special safety instructions

DANGER!

Risk of accidents from improper maintenance and servicing

Incorrect maintenance and servicing and failure to observe the listed safety instructions can lead to accidents and material damage. Make sure of the following:

• Maintenance and servicing work must only be carried out by qualified specialist staff or persons who have received appropriate instruction. • When performing any work on the filter, always wear the appropriate safety

equipment and clothing.

• Only perform maintenance and servicing work when the filter is cooled, depressurised and empty. Depending on the operating temperature, there may be a risk of burns.

• Ensure the highest levels of cleanliness when opening the filter. No foreign substances, e.g. tools, cleaning cloths, impurities etc., must be allowed to remain in the filter.

• Visually inspect all seals during maintenance and replace them as necessary.

• Clean all sealing surfaces thoroughly before assembly.

• On completion of the maintenance work, re-fit all available safety equipment properly.

• Filling the filter against the indicated direction of flow of the filter elements is not permitted.

• Remove the filter from service if the inspection periods (if indicated) have elapsed.

• Filter elements are sensitive to pressure and impact. Always exercise extreme caution when installing and removing the filter elements. Before installation, check all filter elements/seals and replace any damaged filter elements/seals as necessary.

(38)

38 / 58 Operating instructions 6.48 Betriebsanleitung 6.48 CAUTION!

Risk of damage to the filter from incorrect use of cleaning agents

The components of the filter may become damaged if cleaning agents are used incorrectly. The correct cleaning agent is selected in accordance with the type of medium being filtered and the associated contaminations.

• BOLL & KIRCH Filterbau GmbH recommends BOLL CLEAN 2000 cleaning agent. For more detailed information, see the appendix of these operating instructions.

8.3 Special tools

The manufacturer provides the following special tools for the filter:

Tool for removing the filter candles

8.4 Maintenance intervals

Even automatic filters have to undergo regular checks and maintenance. It is particularly important to note that the filter material on the filter elements may become blocked over time despite permanent backflushing. This depends largely on the quality of medium and the available partial flow cleaning function. The contamination in the mesh can be removed by cleaning the filter elements by hand using a suitable cleaning agent.

NOTE

BOLL & KIRCH Filterbau GmbH recommends BOLL CLEAN 2000 cleaning agent. For more detailed information, see the appendix of these operating instructions.

An increasing blockage of the filter elements becomes noticeable from an increasing pressure loss in the filter.

(39)

In order to make sure the automatic filter continues to operate properly, observe the following points for maintenance:

• Regularly check:

– the differential pressure,

– the leak tightness of the automatic filter, especially all connections and seals and

– the automatic filter for corrosion and other damage, – the flushing oil outlet and the optional nozzle for soiling, – the function of the backflushing device and

– the condition of all screw connections and whether they are firmly tightened.

• The automatic filter must be inspected annually for leaks. • Replace all seals at least every 2 years and when overhauling. • Check the condition of the filter elements annually.

If an inadmissibly high level of differential pressure is detected beforehand, all the filter elements must be checked and cleaned as necessary.

If you discover that the protective sieve is heavily contaminated, the automatic filter has been operated for a longer period with contaminated/ faulty filter elements or a faulty backflushing device. The overflow valves have opened from a defined differential pressure level. It is essential that you clean and check the complete filter insert and check that the backflushing device is working.

When regularly checking leak tightness, pay particular attention to the gasket on the inspection glass in the cover which is subjected to dynamic strain. NOTE

The filter elements are subject to wear from two-way strain. It is therefore recommendable to keep a complete set of filter elements in stock.

NOTE

BOLL & KIRCH Filterbau GmbH recommends you replace all the filter elements at the latest after 4 years.

After carefully inspecting the filter elements they may be usable for a longer period. The user must assume all liability of using filter candles for a longer period.

8.5 Cleaning/replacing the filter element on the automatic filter

8.5.1 Preparatory work

X Take the plant out of operation or open the shut-off valves of the by-pass line. X Close the shut-off valves on the connection lines.

DANGER!

Risk of accidents from expelled medium

Hot medium may be expelled when opening the drain hole. • Proceed with extreme caution.

• Wear the appropriate safety equipment and clothing. • Collect the expelled medium in a suitable container.

DISPOSAL

Leaks must be caught immediately. Make sure that expelled medium is disposed of properly and in an environmentally friendly manner.

X Empty the filter. Carefully open the drain hole. X Close the drain hole.

X Unfasten the screw connection on the cover. X Lift the cover off the housing.

8.5.2 Removing the filter insert with filter candles

X Pull the filter insert, including the flushing arms and the cog wheel, out of the housing towards the rotary axis of the flushing arm shaft.

CAUTION!

Damage to the cog wheel

The teeth may become damaged by a build-up of mechanical force.

• Proceed with extreme caution when removing and installing and cleaning the filter insert.

X Allow the filter insert to drip dry in a suitable container. 8.5.3 Cleaning the filter insert with filter candles

NOTE

Under normal operating conditions it is not necessary to clean the filter insert manually. The automatic filter cleaning function keeps the pressure loss in the filter constant. if the pressure loss increases above the permitted value, the filter elements need to be cleaned manually. If the overflow valves have opened, the protective sieve must also be cleaned thoroughly.

(41)

CAUTION!

Risk of damage to the filter insert from improper cleaning

If the filter insert is cleaned or handled improperly, the filter insert may become damaged. Observe the following safety instructions:

• Proceed with extreme caution when performing all cleaning work.

• The soaking time in the "BOLL CLEAN 2000" cleaning agent must not exceed 24 hours.

• The cleaning temperature, when using "BOLL CLEAN 2000" must not exceed 60 °C.

• When cleaning using a high-pressure cleaner, the pressure must not exceed a maximum of 60 bar. When cleaning using a high-pressure cleaner, keep a sufficient distance (at least 20 cm) from the surface of the filter material to prevent damage.

• Particles of dirt must not be allowed to enter the clean side of the filter element.

• Do not place the filter elements on top of each other as you may otherwise cause damage.
