風輪轉(zhuǎn)速明顯降低的現(xiàn)象一般比較直觀。無錫風力風機制造有限公司即有風時。風輪不好啟動，運轉(zhuǎn)時轉(zhuǎn)速上不去，特別是額定風速時，風輪轉(zhuǎn)速達不到額定轉(zhuǎn)速。風輪轉(zhuǎn)速明顯降低的原因分析。變槳距風輪葉片調(diào)速后沒有復位，發(fā)電機軸承損壞，抱閘剎車風輪的剎車帶和剎車盤摩擦過大，風輪葉片變形排除方法。如風輪葉片變形或變槳距葉片沒有復位，進行檢查調(diào)整或更換新風輪葉片，抱閘剎車機型，應檢查調(diào)整剎車間隙，保風輪運轉(zhuǎn)自如，若發(fā)電機軸承損壞，應更換新軸儲能蓄電池的使用和保養(yǎng).小型風力發(fā)電機發(fā)出的電能是通過蓄電池再給用電設備使用的?？茖W地、合理地使用并保養(yǎng)蓄電池，充分發(fā)揮使用效率，延長壽命，是用好風力發(fā)電機的技術(shù)關(guān)鍵。可以說，小型風力發(fā)電機使用的好壞集中表現(xiàn)在蓄電池上。所以，對蓄電池的使用與保養(yǎng)必須引起高度重視。（圖/文http://m.qianjiadong.com.cn/）

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. |
