瓦斯發電機組的風扇皮帶會產生松動的根本原因有哪些呢？可能是老化導致的，其次可能是型號規格不對導致的，也就是 皮帶輪間距偏移導致的，這三個因素關鍵以老化為多見。

What are the fundamental reasons for the looseness of the fan belt of the gas generator set? It may be caused by aging, followed by incorrect model and specification, that is, offset of pulley spacing. Aging is the most common of these three factors.

發電機組風扇皮帶要是產生變松，排風量會很大程度上遭受不良影響，發電機組的散熱排風量供求平衡自然不夠，會導致 整個機械溫度的上升，導致大量損害。

If the fan belt of the generator set becomes loose, the exhaust air volume will be greatly affected. The balance between supply and demand of the cooling and exhaust air volume of the generator set is naturally insufficient, which will lead to the rise of the entire mechanical temperature, leading to a lot of damage.

知道了原因也要知道怎么處理，在傳動帶中部用30-50牛頓的力輕按或拉上，傳動帶與原先部位相差15-20毫米，傳動帶的 松緊度算作一切正常，否則應進行調整。其方式按不一樣結構可分為：

If you know the reason, you should also know how to deal with it. Press or pull the middle part of the transmission belt gently with 30-50 N force. The difference between the transmission belt and the original part is 15-20 mm. The tightness of the transmission belt is considered normal, otherwise it should be adjusted. The methods can be divided into:

是設有張緊輪結構的。可松開固定螺母,擰轉調整螺釘，上上下下挪動張緊輪，做到所想要的松緊度；風扇和發電機同用一 條傳動帶驅使的，可挪動發電機支撐架，更改其皮帶輪部位，做到所想要的松緊度；皮帶輪由兩半組成的，先松開固定螺栓， 之后轉動可調節的半邊皮帶輪，為此更改所合成的皮帶輪糟寬，進而升降三角皮帶，做到所想要的松緊度。

It is equipped with tensioning wheel structure. Loosen the fixing nut, turn the adjusting screw, and move the tensioning wheel up and down to achieve the desired tightness; If the fan and the generator are driven by the same drive belt, the generator support frame can be moved to change the belt pulley position to achieve the desired tightness; The belt pulley is composed of two halves. Loosen the fixing bolt first, and then turn the adjustable half belt pulley. To change the width of the resultant belt pulley, and then lift the V-belt to achieve the desired tightness.

皮帶會在運行一段時間過程中后老化裂開，就變松了，此時此刻便會產生吱吱的異常響聲。有異常響聲的過程中盡量開展 檢驗。

The belt will age and crack after running for a period of time, and become loose. At this moment, it will make an abnormal noise. The inspection shall be carried out as far as possible in the process of abnormal noise.

要是沒有裂開，只需調節松緊程度就可以了。要是裂開了，更換皮帶還有漲緊輪。由于裂開以后，再將皮帶調緊，會導致 皮帶的破裂。皮帶破裂后，發動機就沒辦法正常運行了。對此你還有什么不了解的，歡迎前來咨詢我們網站 http://www.hdlelisa.com。

If there is no crack, just adjust the tightness. If it is cracked, replace the belt and tension pulley. As the belt is tightened after cracking, the belt will break. After the belt is broken, the engine cannot run normally. What do you not know about this? Welcome to consult our website http://www.hdlelisa.com 。
