离心风机应急停机情况
Emergency shutdown of centrifugal fan
离心风机开展应急停机的情况，其具体来讲的话，主要是有下面这些，是为：
The emergency shutdown of centrifugal fan mainly includes the following:
情况一：离心风机的震动过于明显，并且，早已超过了跳闸值。
Case 1: The vibration of the centrifugal fan is too obvious and has already exceeded the trip value.
情况二：离心风机运作时会异响，例如其内部有碰刮，或者不正常的磨擦响声。
Case 2: The centrifugal fan will make abnormal noise during operation, such as scratching or abnormal friction sound inside.
情况三：风机轴承温度急剧上升，而且，早已超过了设置的上限值，或者，其轴承或密封处起烟。
Scenario 3: The temperature of the fan bearing rises sharply, and it has already exceeded the set upper limit value, or the bearing or sealing area may smoke.
情况四：离心风机油压过低，而且，没法自主恢复过来。或者，油箱中出现了吸空状况。
Situation 4: The oil pressure of the centrifugal fan is too low, and it can not recover on its own. Alternatively, there may be an empty suction condition in the fuel tank.
情况五：离心风机的轴向位移值一直增大，而且，超过了报警值。
Case 5: The axial displacement value of the centrifugal fan has been increasing and exceeded the alarm value.
