风轮转速明显降低的现象一般比较直观。无锡风力风机制造有限公司即有风时。风轮不好启动，运转时转速上不去，特别是额定风速时，风轮转速达不到额定转速。风轮转速明显降低的原因分析。变桨距风轮叶片调速后没有复位，发电机轴承损坏，抱闸刹车风轮的刹车带和刹车盘摩擦过大，风轮叶片变形排除方法。如风轮叶片变形或变桨距叶片没有复位，进行检查调整或更换新风轮叶片，抱闸刹车机型，应检查调整刹车间隙，保风轮运转自如，若发电机轴承损坏，应更换新轴储能蓄电池的使用和保养.小型风力发电机发出的电能是通过蓄电池再给用电设备使用的。科学地、合理地使用并保养蓄电池，充分发挥使用效率，延长寿命，是用好风力发电机的技术关键。可以说，小型风力发电机使用的好坏集中表现在蓄电池上。所以，对蓄电池的使用与保养必须引起高度重视。（图/文http://www.wxfengli.com/）

The wind wheel rotational speed was significantly reduced wind speed was significantly reduced in the phenomenon, generally more intuitive. That is when the wind wheel wind a bad start, running speed to go up not to go, especially the rated wind speed, wind speed is not up to the rated speed. The wind wheel rotational speed was significantly reduced and the cause analysis. Variable pitch wind turbine generator after the speed is not reset, bearing damage, contracting brake wind wheel brake band and the brake disc friction is too large, the wind wheel blade deformation elimination method. The wind wheel blade deformation or variable pitch blades without reduction, are examined to adjust or replace the wind wheel blade, contracting brake type, should be checked for adjusting brake clearance, and the wind wheel to operate freely, if the generator bearing damage, you should replace the new axis energy storage battery use and maintenance of small type wind power generator can generate electric power by the battery for the electric device using. The scientific, rational use and maintenance of storage battery, give full play to use efficiency, prolong life, is the use of wind power generator technology. Can say, small wind turbines use is concentrated in the battery. Therefore, the battery use and maintenance to must cause height to take seriously.
