1. 每次安裝或調(diào)整電機(jī)時(shí)，應(yīng)對(duì)比葉輪得轉(zhuǎn)向與旋向標(biāo)相一致。
2. 當(dāng)發(fā)生風(fēng)量不足，噪音增大以及風(fēng)機(jī)震動(dòng)時(shí)，首先檢查風(fēng)機(jī)旋向。                                                                                                     Even if the fan reverses,it will still produce air flow。So it can not be judged that the fan is in normal operation by whether ther is air fiow;in order toprevent reverse rotation。the following contents should be checked：
3. The power supply to the rotating motor shall be consistent with that of the rotating motor each time。
4. 2.When the air volume is insufficient，the noise increases and the fan vibrates，the rotation direction of the fan shall be checked first
