Brief description 2StufenFilterelement für Schmiersysteme The Filtration Group 2stage filter element with the unique Premium Select element structure, with integrated reliable bypass valves and the sturdy safety insert is used as for gear oil filtration in wind turbine plants. These filter elements are used in the oil filter modules Pi 8300 and the lowpressure filters Pi 260. Filter elements with two filtration stages for the filtration of lubricating in wind turbine gearboxes Unique, multilayer Filtration Group Premium Select (PS) folding starshape filter design made of chemically and thermally resistant materials. Filter performance that fits like a glove: A forcefit fixing fleece material presses the folding starshape tight to the supporting body and fixes the folds in place in such a way as to prevent block formation. At the same time, the fixing fleece takes over a prefilter function. Progressive structure: The degree of fineness of the glass fibre material decreases from the inside to the outside, combining the advantages of a depth filter with those of a large effective filtering surface. The result: greater dirt pickup capacity even at lower pressure loss in conjunction with a defined discharging rate (multipass test in compliance with ISO 16889). Supporting fibre on both sides made of highquality stainless steel ensures the high rigidity of the folding starshape. Chemical resistance is guaranteed by the use of highgrade stainless steel wire mesh. Supporting body and end plates are made of materials free of chromium VI. Suitable for universal use for hydraulic and lubricating fluids, fuels, aqueous media and synthetic fluids. Low initial differential pressure Version for Filtration Group filter housing, as alternative elements in the dimensions of other manufacturers and in customerspecific designs.

3 The filter element is the central component in which the filtration process takes place. The 2stage filter elements used for lubricating oil filtration in wind turbines are a combination of depth filter (1 st filter stage glass fibre) and surface filter (2 nd filter stage wire mesh). The direction of flow through the 2stage filter element is from the outside to the inside. The first filter stage (1), the multilayer starpleated depth filter, is responsible for the prescribed purity class being achieved. Inside the first filter stage, the protection filter (2) is installed in such a way that only filtered oil is allowed to flow into the gearbox There are 2 operating modes, normal mode and bypass mode Normal mode: The bypass valves (3) in the upper end plate are closed so that the unfiltered oil flows through the 1 st filter stage (1), the depth filter. Then the prefiltered oil flows the 2 nd filter stage (2), the surface filter. Bypass mode: With a lubrication system cold start, the viscosity of the lubricating oil (ISO VG 3) can be so high that the pressure built up at the filter element is high enough to open the bypass valves (3). This means that part of the unfiltered oil flows past the first filter stage (1) and gets into the inside of the 2stage filter element unfiltered and flows through the second filter stage (2). This guarantees that the wind turbine gearbox is always supplied with filtered oil. Standard mode Bypass mode measured in accordance with ISO (multipass test) PS elements with max. p bar ß 5(C) 0 ß 7(C) 0 ß (C) 0 ß (C) 0 up to bar differential pressure y = beta value x = particle size [µm] determined from multipass measurements (ISO 16889) Calibration in accordance with ISO (NIST) In a hydraulic or lubricating system, the filters have the task of keeping the soiling level of the fluid to the required level by filtering out particulate matter and keeping this level constant over a long operating period. In industrial hydraulics, it is usual to use codes for the numbers of particles in accordance with ISO 4406 to mark solid impurities. The purity classes which can be achieved with PS filter elements are listed below. These values reflect our long years of experience in designing hydraulic filters and are to be viewed as reference values. Filter elements 2stage filter element for lubricating systems 3

The fineness levels usual in the gear oil filtration of wind power plants are 40 µm (mesh weave: twill) and 50 µm (weave: single lacing). In the case of wire mesh elements the filter fineness is the diameter of the largest spherical particle that can just about pass through the mesh. Wire mesh elements are used in hydraulic and lubricating oil filtration as suction filters or coarse filters, with highviscosity media as well as in safety filters in cooling lubricant filtration. Wire mesh elements have a sharp cut point as surface filters and a lower dirt pickup capacity than depth filters. 4.

6 2. Preface Filter elements are the virtual part of a filter through which the filtration process is realised. For the different liquids and applications Filtration Group developed different filter materials. Therefore a variety of elements are available which would fit into the same housing, but would suit different applications. 3.1 PS and SmN Depth filters consisting of several layers of glass fibre (progressive design) to filter hydraulic oils and lubricants, flame resistant liquids, fuels and synthetic liquids. PS is available in ratings of 5 µm (c), 7 µm (c), µm (c), 15 µm (c) and µm (c) according to ISO (3µm, 6 µm, µm, 16 µm and 25 µm according to ISO 4572) with a very high dirt holding capacity and simultaneous very low flow resistance. SmN 2 is available in ratings of 4 µm (c) according to ISO (2 µm according to ISO 4572) with an extremely high dirt holding capacity for very demanding requirements in regards to the filtration quality, for offline filtration and for singlepass applications. _ Separation grade characteristics Filter performance data 1 tested according to ISO (multipass test) 3 PS/SmN elements with max. p bar 12 y = betavalue x = particle size [µm] 14 determined by multipass tests (ISO 16889) calibration according to ISO (NIST) 5 SmN 2 β4(c) 0 PS 3 β5(c) 0 PS 6 β7(c) 0 PS β(c) 0 PS 16 β15(c) 0 PS 25 β(c) 0 values guaranteed up to bar differential pressure. In a hydraulic or lubrication system a filter has the task to reduce the contamination to the accepted cleanliness level and to keep it for as long as possible. For the identification of solid particles in industrial hydraulics it is common practice to count particles according to ISO Subsequently the achievable cleanliness classes of the Smx and SmN. These values mirror our longtime experience in designing hydraulic filters and could be considered as guide values. _ Cleanliness classes Cleanliness classes according to ISO 4406 (1999), > 4 µm(c)/ > 6 µm (c)/ >14 µm (c) SmN 2 13/11/08 14/12/09 16/13/ 17/15/11 /17/12 23/19/ Smx Deep filters with glasfibre filter material for all purposes. Filter performance, retention rates and the achievable cleaniness classes are fully corresponding to the new PS filter material. 2

8 3.6 s WSMic, WSSmx and WSSmN Filtration Group WSelements for water removal are available as water absorber elements WS with a low filter efficiency for particles or in combination with the highly efficient SmN 2 and Smx configuration. A super absorper will change its chemical structure while absorbing water and indicates the amount of absorbed free water by an increase of flow resistance. The free water will be absorbed until the saturation limit is reached. WSelements are applicable for all common lubrication and hydraulic fluids. The filter property complies with the corresponding Mic, Smx and SmN 2 element. The flow resistance of a waterfree liquid would be insignificantly higher. 4.

28 2. Description Charge separation in fluid systems is a wellknown phenomenon in highperformance filters (filter fineness < µm). Charge separation occurs during perfusion of the filter's fine pores due to the viscous friction between the oil molecules and the surface of the fibre. Electron transfer takes place as a result of the close contact between the friction partners. The intensity and direction of the electron transfer depends on the material properties of the friction partners (triboelectric series). Depending on the electric properties of the filter material and of the oil, there is a subsequent charge equalisation or charge accumulation (after charge separation). With the fluids that have dominated the market so far, the charge separation is equalised again depending on the socalled relaxation time so that there are no noticeable effects in the fluid components including the filter elements or in the fluids (TRBS 2153). A significant increase of electrostatic charge within the fluid systems can have many causes: Low retention time due to increasingly compact systems with low oil volumes Increasing filtration requirements, even in lubrication applications Increased application of environmentallyfriendly zinc and ashfree oils To prevent electrostatic charges, the conductivity of the fluid should be at least 500 ps/m. With the new zinc and ashfree hydraulic oils however, there are fluids on the market that are far below the minimum conductivity mentioned above, which can lead to increased electrostatic charges. x = Oil temperature C y = Conductivity ps/m 1 = Highalloy hydraulic oil, contains Zn 2 = Synthetic ester (HEES) 3 = Lowalloy hydraulic oil, Znfree 3. Practical consequences If these requirements are satisfied, electrostatic charges can occur in the filter element and in the fluid, which are equalised through local discharge with a higher energy. Indicators of intense discharge processes range from audible crackling to detectable damage in the filter layers and components. Effects on oil ageing and the appearance of "varnish" plus the malfunction of electronic components cannot be excluded. However, these depend on additional limiting conditions in the respective system. Filters that prevent electrostatic discharge must be used when high viscosity lubricating oils are utilised with fine filters as well as in the field of power plant technology.
