一、风机正常运行2-3小时后，停机检查，调整皮带。

Stop and Adjust V-belts after blower normally operation 2-3 hours later.

调整皮带的步骤 V-belts adjust steps：

1.首先将电机底座下固定横担的4个螺栓松开，但不要卸掉。

Loose but don't unload the 4 bolts which are located under motor base frame.

2.将电机后面的1个顶丝松开用电机前面的2个顶丝将电机水平往后移，根据皮带松紧的程度不同，可将电机后顶5—25mm不等。

Loose 1 top bolt then move the motor backward with the front 2 top bolts. The motor could move 5-25mm according to belts tightness difference.

3.然后用直尺校正风机轮与电机轮是否平行，误差在1mm之内正常，最后将顶丝备紧，横担螺丝紧固。

Adjust with straight rule, make sure blower pulley and motor pulley parallel (allowable deviation is within 1mm). At last, tighten top bolts.

4.切记一定要保持每根皮带松紧度一样。

Make sure each belt's tightness same with each other.

二、如皮带松动，会造成以下问题V-belts loose will cause below problems:

1.皮带与皮带轮打滑，磨损皮带，造成皮带断裂。
