如何对回转风机做运行检查？

在对济南风机机械调试时，应该仔细阅读产品说明书，检查接线方式是否与接线图一致;仔细检查风机电源工作电压是否符合要求，电源是否异相或同相，电气元件容量是否符合要求。

During the mechanical commissioning of Jinan fan, carefully read the product manual and check whether the wiring mode is consistent with the wiring diagram; Carefully check whether the working voltage of fan power supply meets the requirements, whether the power supply is out of phase or in phase, and whether the capacity of electrical components meets the requirements.

建议调试期间至少有两人，一人控制电源，一人观察风机运行情况。如发现异常，应立即停机检查;首先，检查旋转方向是否正确;风机开始运行后，立即检查各相运行电流是否平衡，是否大于额定电流;如有异常，应停机检查。运行5分钟后，关闭风机检查是否有异常，确认无异常后再启动运行

It is recommended that there should be at least two people during commissioning, one to control the power supply and one to observe the operation of the fan. In case of any abnormality, stop the machine immediately for inspection; First, check whether the rotation direction is correct; After the fan starts to operate, immediately check whether the operating current of each phase is balanced and whether it is greater than the rated current; In case of any abnormality, stop the machine for inspection. After 5 minutes of operation, shut down the fan, check whether there is any abnormality, and start the operation after confirming that there is no abnormality

启动前检查：

Pre startup inspection:

检查管道的地脚螺栓、风机主体、附件、连接件是否紧固，螺栓、螺母是否均匀锁紧，避免局部过紧或过松。

Check whether the anchor bolts, fan main body, accessories and connectors of the pipeline are fastened, and whether the bolts and nuts are evenly locked to avoid local over tightening or over loosening.

检查离心风机及管路内部是否有异物。安装过程中是否忘记工具或其他杂物;风机进出口附近是否有危险因素。

Check whether there are foreign matters inside the centrifugal fan and pipeline. Whether tools or other sundries are forgotten during installation; Whether there are dangerous factors near the inlet and outlet of the fan.

带水冷轴承的风机，检查冷却水管路的供水情况是否正常。

For the fan with water-cooled bearing, check whether the water supply of the cooling water pipeline is normal.

对于联轴节或皮带驱动的风机，检查联轴节或皮带轮的安装是否可靠，V带的张力是否合适

For the fan driven by coupling or belt, check whether the installation of coupling or belt pulley is reliable and whether the tension of V-belt is appropriate

调试：

Commissioning:

完成上述程序并确认所有项目正常后，可启动风机进行试运行。

After completing the above procedures and confirming that all items are normal, the fan can be started for trial operation.

打开电源开关3~6秒，立即切断电源，确认风机气流方向和叶轮旋转方向是否正确;注意观察有无异常声音、振动等，如有异常，试运行前应按上述流程对机组进行复查和校正。

Turn on the power switch for 3 ~ 6 seconds, cut off the power immediately, and confirm whether the air flow direction of the fan and the rotation direction of the impeller are correct; Pay attention to observe whether there is abnormal sound, vibration, etc. if there is any abnormality, recheck and correct the unit according to the above process before trial operation.

一般情况下，风机启动时，电机的瞬时电流为其额定电流的5~7倍，然后逐渐减小并稳定。如果电流下降速度太慢，停止操作并检查电机的供电系统。

Generally, when the fan is started, the instantaneous current of the motor is 5 ~ 7 times of its rated current, and then gradually decreases and stabilizes. If the current drops too slowly, stop the operation and check the power supply system of the motor.

对于装有调节阀的机组，启动后应逐渐将启闭程度调整到合适的流量。同时注意电流的变化，确保电机空载运行。

For units equipped with regulating valves, the opening and closing degree shall be gradually adjusted to the appropriate flow after startup. At the same time, pay attention to the change of current to ensure the no-load operation of the motor.
