1.离心风机电动机电流量过大：
1. Motor current of centrifugal fan is too large:
在离心风机工作中的情况下，为了更好地确保其处在一切正常的运行状态，大家必须为其出示一切正常的电源电压，但是，也是有一些要素会造成其的电动机电流量上升。例如因为遭受滚动轴承箱的强烈振动的危害，或是是在开启罗茨鼓风机的情况下，其的进、排气管路的水利闸门沒有立即关掉，或是是主轴轴承的转速比过大，超出了标准值，或是是斜流风机电动机的键入工作电压过低，或是是电动机单项工程关闭电源等，这种难题都是会导致电动机电流量提升，进而导致机器设备溫度上升的难题。
When the centrifugal fan is working, in order to better ensure that it is in all normal operating conditions, everyone must show it all the normal power supply voltage. However, there are also some factors that will cause its motor current to rise. For example, due to the strong vibration of the rolling bearing box, or when the Roots blower is turned on, the hydraulic gates of the intake and exhaust pipelines are not immediately closed, or the speed ratio of the main shaft bearing is too large, exceeding the standard value, or the input working voltage of the diagonal flow fan motor is too low, or the power supply of the motor is turned off in a single project, these difficulties can lead to an increase in the current flow of the motor, This leads to the problem of temperature rise in machine equipment.
2.离心风机滚动轴承升温过高：
2. The temperature of rolling bearing of centrifugal fan is too high:
针对这一部分的內容，我们可以根据四个层面来考虑到，可能是因为离心风机的滚动轴承机盖与座联接地脚螺栓的力距过大或是是过小；第二是因为滚动轴承箱发生了较为强烈的震动难题；第三离心风机的滚柱轴承被毁坏；第四是因为润化不够，或是是在其中带有较多的残渣。
For the content of this part, we can consider from four aspects, which may be because the force distance between the rolling bearing cover of the centrifugal fan and the foundation bolt connecting the base is too large or too small; The second reason is that the rolling bearing box has experienced a relatively strong vibration problem; The roller bearing of the third centrifugal fan was damaged; The fourth reason is due to insufficient wetting or the presence of a large amount of residue in it.
