Power units 动力单元
The power unit is the heart of the turbine, supplying the power necessary to operate pitch, yaw and braking systems and providing backup in case of power failure, ensuring a safe stop with no risk of damage. Our hydraulic power units are designed with reliabilty, ease of maintenance and a wide operating temperature range in mind.
动力单元是风轮机的心脏，为浆距、偏航和制动系统的运行提供必要的电力，并在断电时提供备用措施，保证安全停止，无损坏危险。我们的液压动力单元在设计时充分考虑了可靠性、维护方便性及宽温度范围。

Braking systems 制动系统
Braking systems are used as a parking brake for servicing, for slowing down to a halt safely and to maintain a constant speed when the turbine is transmitting power. The components face serious demands on reliability, low leakage, long stand-by-time and compactness to survive tough operating conditions and comply with safety regulations – demands that are surpassed by Parker’s dedicated products.
制动系统用作工作时的停车制动、减慢到安全停止状态及使风轮输电时保持在恒速状态。在可靠性、低泄漏水平、长备用时间及结构紧凑以满足苛刻的运行条件并符合安全规范方面，部件面临严格的需求，Parker的专门开发产品已超过了这些需求。
Integrating real-time intelligence in the gearbox filtration system 在减速箱过滤系统中集成实时智能
Parker’s system-matched filtration solutions have proven to be effective to extend the life time of critical components such as bearings. Combined with long filter element life time, the utilization rate of the complete wind turbine is increased – an important aspect when service costs are at a premium. Our Condition Monitoring product offering integrates real-time accurate and low cost monitoring of the lubrication fluids condition. Our sensing and communication modules ensure an easy ‘plug and operate’ linkage with control management systems.
Parker的系统匹配过滤解决方案已证明可有效地延长关键部件如轴承的寿命。与长寿命的滤芯相结合，整个风轮机的利用率可得到提高– 在维护费用昂贵的情况下，这一点非常重要。针对润滑流体状态，我们提供的状态监控产品集成有实时精确且低成本监控特性。与控制管理系统相结合，我们的传感系统及通信模块确保“插入即可运行”，使用方便。
Pitch systems 浆距系统
Dynamic pitch systems with specially designed cylinders, with fully protected internal transducers on which intgrated blocks containing all necessary valves are mounted, are placed inside the hubs. This necessitates reliable performance, maintenance accessibility and integrated safety functions. Parker can supply integrated systems with every component needed, including high performance electronic control valves compatible with any modern wind turbine control system. The pitch control can be combined with a technically advanced axis controller for pitch and maximum force control, bringing about high-accuracy blade control and permanent control of the mechanical load on the blades.
动态浆距系统安装在中心孔内，带有特殊设计油缸，内部变送器安装有包含所有必要阀门的集成阀块，可得到完全的保护。这就使性能可靠、易于维护及内置安全功能成为必要条件。Parker能够提供附带各种所需部件的集成系统，包括能与任何现代风轮机控制系统兼容的高性能电控阀门。浆距控制可以与技术先进的轴控制器相结合，进行浆距和最大受力控制，可带来高精确浆片控制及浆片机械负载持久控制。
