混凝土搅拌机电压需要注意什么大家知道吗?

  (1)监控混凝土搅拌机电机的负载电流。电机故障时,定子电流急剧增大,电机过热。装有大功率混合器的电机应装有电流表,以监测电机的负载电流。电机的负载电流不得超过铭牌上规定的额定电流。
  (1) Monitor the load current of the concrete mixer motor. When the motor fails, the stator current increases sharply and the motor overheats. Motors equipped with high-power mixers shall be equipped with ammeters to monitor the load current of the motors. The load current of the motor shall not exceed the rated current specified on the nameplate.
  (2)监控电源电压频率变化和电压不平衡,电源电压和频率过高或过低,由三相电压不平衡引起的电流不平衡可能导致电机过热或其他异常现象。

  (2) Monitor the power supply voltage frequency change and voltage imbalance. The power supply voltage and frequency are too high or too low. The current imbalance caused by the three-phase voltage imbalance may cause motor overheating or other abnormal phenomena.
  (3)缠绕混凝土搅拌机的转子电机应在夜间检查电刷与滑环的接触及电刷室的损坏情况,防止产生火花。若火花严重,应及时清理滑环表面,纠正电刷弹簧压力。
  (3) The rotor motor winding the concrete mixer shall check the contact between the brush and the slip ring and the damage of the brush chamber at night to prevent sparks. If the spark is serious, clean the slip ring surface in time and correct the brush spring pressure.
  (4)定期检查轴承的润滑情况。定期更换润滑油时,应先用煤油清洗轴承和轴承盖,再用汽油清洗。滚动轴承润滑脂不得超过轴承室容积的70%。
  (4) Check the lubrication of bearings regularly. When changing lubricating oil regularly, clean the bearing and bearing cover with kerosene first, and then clean with gasoline. The lubricating grease of rolling bearing shall not exceed 70% of the volume of bearing chamber.
  (5)注意保持电机清洁。混凝土搅拌电机内不得有水、油脂或杂物。混合器电动机的进出口必须保持畅通。
  (5) Keep the motor clean. There shall be no water, grease or sundries in the concrete mixing motor. The inlet and outlet of mixer motor must be kept smooth.
  (6)注意电动机的气味、振动和噪声,如有焦味或运转中出现异常振动或磨擦、超大型嗡嗡声等噪声,应立即切断电源进行检查。
  (6) Pay attention to the smell, vibration and noise of the motor. If there is burning smell or abnormal vibration or friction, super large buzzing and other noises during operation, cut off the power supply immediately for inspection.
