适用于SKF MonoFlex单线润滑系统的带泄压阀的单线齿轮泵本手册中产品的CAD模型可从以下网址获得：一般信息SKF MonoFlex齿轮泵每次行程的排量有限，这会限制出油量和系统扩展。

这些泵均配备活塞分配器运行所需的泄压设备。

当泵活塞回到正常位置时，还需要通过泄压阀来为主管路泄压。

系统规划时必须考虑系统的润滑需求量。

为了确保所需压力的建立，柱塞泵的排量应至少为润滑需求量的 . 倍。

当规划流体润滑脂系统时，在确定润滑需求量时必须将润滑脂的压缩率（约1%）考虑在内。

润滑需求量包含：系统分配器测得的总量该值的+ %（安全余量）主管路+ cm /m（扩展损失）使用流体润滑脂时的压缩率损失SKF专家可以为您提供更多信息调试如需调试产品，在油箱中填入润滑剂并且以 - 秒间隔启动泵，直至所有润滑点上都有润滑剂排出。

通过以下方式进行排气操作：• 打开主管路的两端，直至从两端排出无气泡的润滑油或流体润滑脂。

• 在连接润滑点之前，特别是针对一些小排量的出口管路，一定要先预填充长的润滑管路。

维护检查液位并及时填充油箱。

Contact can cause burns and must be prevented.Also no temperature-sensitive components,e.g.normal cable or electronically parts,should lie close or has to be fastened at the housings.1.2.1Transport regulationsGeneralThis regulation describes the handling for the components manufactured by SSB(switch cabinets and electric motors)for the pitch system:The regulation is to be considered with each unloading and transportation procedure.The carrier is responsible to adhere the requirements of SSB and has to fulfill the legal regulation concerning the transportation lock and the transport insurance.Attention should be paid to:•Using a fork-lift truck the load has to be secured against overbalancing and slipping down from the pallet!•Transporting several switch cabinets on a pallet these are to be secured against slipping,because otherwise a damage of the housing can occurNoteStrong vibrations and hard impacts are to be avoided during transport as well as when lifting and setting down!1.2.2Storage of SSB Pitch SystemsGeneralThis regulation describes the correct storage of the components for the pitch system, manufactured by SSB:The storage contains:•the keeping of the SSB components up to the intended installation of the products into a wind energy plant•the keeping of the inserted components in a plant component up to the evacuation of the component to the building site.For the handling the transportation regulation is to be considered.The following items have to be considered:•The components that are not fitted must be stored in a closed hall•The hall temperature is to be maintained in the range of0°C to+40°C•During storage the relative humidity should be between0%and55%•In the case of temperatures lower than0°C care must be taken to ensure that the heating systems are in good working order so as to achieve an internal cabinet temperature of>0°C•Built-in battery packs are to be protected against discharging by regular trickle charging•During storage the components are to be protected against high humidity and water condensation inside the housing by suitable drying agents•Battery cabinets and pitch motors are not stackable•A maximum of up to3converter cabinets or3control cabinets can be stacked.When doing so,ensure that the external converter box heat sink is not damaged during storage•For protected transport,housing openings must be closed by plugs or adhesive tape and must also remain closed to prevent the ingress of foreign bodies •All housings must always remain closed during storage•The temporary corrosion protection of the unpainted fixing flange in pitch motors must be renewed at regular intervals.2Pitch system layoutThe pitch-system is placed inside the hub of the wind power plant.The scope of supply includes one main pitch ctrl.cabinet,three axis cabinets,three battery cabinets,three direct current electric motor,the required cable connections and the operating manuals.The pitch control system and speed control work together to maintain the rotor at constant power output.Wind gusts cause the rotor to accelerate,but subsequent adjustment of blade pitch smoothly reduces the speed once again.This leads to a significant reduction of the loads on the turbine while at the same time the power is supplied to the grid with a high level of compatibility.In order to maintain blade pitch in the event of grid loss or failures in the pitch power supply or control units,each rotor blade has its own battery back-up that rotates with the blade.In addition to controlling power output,the pitch mechanism serves as the primary safety/ brake system.Each blades pitch mechanism operates independently of the others.Thus in the event of a storm each blade can be moved to a safe position(feather position)to restore the rotor from abnormal situations to safe rotational speeds.Fig.2.1:plot of the pitch system layout2.1Main pitch ctrl.cabinetThe main pitch ctrl.cabinet is the interface between the axis cabinets in the hub and the top box,located in the machine house.The connection between the main pitch ctrl.cabinet and the top box is realized by slip ring. Via this slip ring the main pitch ctrl.cabinet is supplied with power and control signals from the top box.Additionally a Profibus-DP connection for the data exchange between the system management computer and the pitch controller is performed via slip ring.The positioning controller is mounted in the main pitch ctrl.cabinet and controls the positioning of the blades.In addition,the charging process of the back-up system(batteries) in the three battery cabinets is controlled by a central charging unit fitted in the main pitch ctrl.cabinet.Fig.2.2:Main pitch ctrl.cabinet2.2Axis cabinetsThere are three axis cabinets in the pitch system.One axis cabinet is allocated to each blade.The converter operates in4-quadrant mode to control the speed of the corresponding pitch motor.Fig.2.3:Axis cabinet2.3Battery cabinetsLike the axis cabinet,one battery cabinet is allocated to each axis.For the case of a power failure or a reset of the EFC-signal(Emergency Feather Control-signal)each blade will be separately moved to the feather position(limit switch).Fig.2.4:Battery cabinet2.4Electric pitch motorsThe electric pitch motors are direct current machines.Fig.2.5:Electric pitch motorDetailed information concerning the motor(technical data,maintenance etc.)is contained in the appropriate document“Operating instructions for SSB DC Motors Model:GHTIF-07200403.81”2.5Pre-installed cablesThe connection between the main pitch ctrl.cabinet and the top box is realized by slip ring. Via this slip ring the main pitch ctrl.cabinet is supplied with power and control signals from the top box.Additionally a Profibus-DP connection for the data exchange between the system management computer and the pitch controller is performed via slip ring.The connection between the main pitch ctrl.cabinet,the axis cabinet,the battery cabinets and the electric pitch motors is made by pre-installed cables.The delivered cables are coded to prevent an interchange between cables and cabinets.3Mechanical dimension drawings3.1Main pitch control cabinetFig.3.1:Dimension drawing main ctrl.cabinet3.2Axis cabinetFig.3.2:Dimension drawing axis cabinet3.3Battery cabinetFig.3.3:Dimension drawing battery cabinet3.4Pinion encoder blade bearingFig.3.4:Dimension drawing pinion encoder blade bearing4Commissioning4.1Installation of the componentsNoteThe installation of the components and the connecting cables should only be carried out by qualified personnel.WarningThe installation and the cable connection are only to be carried out if all power supplies are disconnected or switched off.The pitch system is to be disconnected from power supply until all components are correctly installed and connected to each other.The batteries for the emergency power supply are already installed.For this reason,the battery maintenance switch must be switched to“off”and only switched to“on”after all connections are made. Caution is needed if the battery cabinet is open and the batteries are interconnected,since there is a voltage of216VDC between positive and negative terminals.WarningThe installation of the pitch system must be carried out with great care.There is a risk of injury or death related to the great dead weight of the components as well as from pointed and sharp edges.Lifting and transporting must be carried out with suitable lifting and transporting equipment(see also Chapter1.2).4.2Mounting the switch cabinetsFig.4.1:Holding rail for the cabinetsFor installing the cabinets inside the hub,the switch cabinets have retaining brackets to which they can be attached with screws or bolts in frames designed for the purpose.When doing so,a firm fit must be ensured.The fastenings can become loose through vibrations in the hub during operation of the wind energy plant,so the screws or bolts must be secured against becoming loose independently.A dynamic suspension is recommended,to protect the cabinets against damage caused by the vibrations.4.3Installation of the pitch motorFig.4.2:Pitch motor4.4Connecting the cablesCautionDo not remove the coding of the plug pare the coding of the plugs with the coding on the cabinets.The inscriptions have to correspond.If the coding at the plug and cabinet is equal,but the inscriptions are different,please contact SSB.Mixing up connections can cause malfunctions in the pitch system and a damage of the plant.Fig.4.3:Connectors at the axis cabinet and the battery cabinetIf all components (cabinets and motors)are installed in the hub,the pre-wired cables can be connected.The plug system is marked and secured by coding pins.5Manual OperationWarningManually movement of the blades can present a risk for personnel and the wind energy plant if not carried out correctly.All essential safety precautions must be taken before a manual operation of the pitch system is undertaken.For this purpose,the appropriate operating instructions are to be consulted and the plant manufacturer’s safety measures are to be noted.WarningOnly one blade should be moved out of the parking position.Consequently,before moving a second blade,it must be ensured that the first blade is in parking position again.5.1General information motion controller GEL8230Y001The Motion Controller is intended exclusively for the control of rotor blade drives in a wind power plant.The three axes are equipped with a redundant encoder system.Encoder A:located at the motor shaftEncoder B:located at the blade bearingIn case of an invalid encoder signal it is possible to select the second encoder set.Control and nominal value preset are carried out by means of an attached field bus module (PROFIBUS-DP)using the specific communication protocol"LB2".The controller measures the motor currents of the three axes via current transducer connected to analog current inputs and three temperatures via analog PT100inputs,and provides averaged values.The values can be accessed via the LB2protocol(8bits)or converted and displayed as motor current in Ampere or as temperature in degrees Celsius respectively.A brief overview of the method of functioning and the operation of the controller is given here. The operator interface and the menu guidance are only for display and do not equate strictly to the supplied version in terms of the controller layout and software.NoteFor general information,safety instructions etc.or a detailed description of the controller, consult the supplied manual.5.2Characteristic motion controllerThe following sketch shows the principle of functioning of the

优点：机械结构简单，易于制造；控制原理简单，运行可靠性高。

缺点：额定风速高，风轮转换效率低；电能质量差，对电网影响大；叶片复杂，重量大，不适合制造大风机变桨变速型风电机组风机的每个叶片可跟随风速变化独立同步的变化桨距角，控制机组在任何转速下始终工作在最佳状态，额定风速得以有效降低，提高了低风速下机组的发电能力；当风速继续提高时，功率曲线能够维持恒定，有效地提高了风轮的转换效率。

优点：发电效率高，超出定桨机组10%以上；电能质量提高，电网兼容性好；高风速时停机并顺桨，降低载荷，保护机组安全；叶片相对简单，重量轻，利于制造大型兆瓦级风机缺点：变桨机械、电气和控制系统复杂，运行维护难度大。

变桨距双馈变速恒频风力发电机组成为当前国内兆瓦级风力发电机组的主流。
