瓦斯发电机组的风扇皮带会产生松动的根本原因有哪些呢？可能是老化导致的，其次可能是型号规格不对导致的，也就是 皮带轮间距偏移导致的，这三个因素关键以老化为多见。

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.

发电机组风扇皮带要是产生变松，排风量会很大程度上遭受不良影响，发电机组的散热排风量供求平衡自然不够，会导致 整个机械溫度的上升，导致大量损害。

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处理，在传动带中部用30-50牛顿的力轻按或拉上，传动带与原先部位相差15-20毫米，传动带的 松紧度算作一切正常，否则应进行调整。其方式按不一样结构可分为：

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:

是设有张紧轮结构的。可松开固定螺母,拧转调整螺钉，上上下下挪动张紧轮，做到所想要的松紧度；风扇和发电机同用一 条传动带驱使的，可挪动发电机支撑架，更改其皮带轮部位，做到所想要的松紧度；皮带轮由两半组成的，先松开固定螺栓， 之后转动可调节的半边皮带轮，为此更改所合成的皮带轮糟宽，进而升降三角皮带，做到所想要的松紧度。

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.

皮带会在运行一段时间过程中后老化裂开，就变松了，此时此刻便会产生吱吱的异常响声。有异常响声的过程中尽量开展 检验。

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.

要是没有裂开，只需调节松紧程度就可以了。要是裂开了，更换皮带还有涨紧轮。由于裂开以后，再将皮带调紧，会导致 皮带的破裂。皮带破裂后，发动机就没办法正常运行了。对此你还有什么不了解的，欢迎前来咨询我们网站 。

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 。
