【Frequently Asked Questions】
Q: What are the maintenance points of ultra high efficiency explosion proof motor?
Regularly check whether the ultra high efficiency explosion proof motor shell is damaged or deformed to ensure the integrity of the explosion-proof structure; check the junction box to ensure that the wiring is firm, without looseness or oxidation; monitor the motor operating temperature and vibration, and troubleshoot the fault in time when abnormal; replace the grease at the prescribed time to prevent bearing wear.
Q: What are the starting methods of ultra high efficiency explosion proof motor?
Common ones are direct start, star-delta start and soft start. Direct start is simple, but the starting current is large and has a great impact on the power grid; star-delta start can reduce the starting current and is suitable for light load start; soft start starts smoothly by adjusting the conduction angle of the thyristor, which has little impact on the power grid and equipment and can effectively protect the motor.
Q: What is the reason for the abnormal noise of ultra high efficiency explosion proof motor during operation?
The reason why the ultra high efficiency explosion proof motor makes abnormal noise during operation may be that the bearing is worn, resulting in an increase in the gap between the ball and the raceway, which generates noise during operation; it may also be that the internal parts of the motor are loose, such as the fan blades are not firmly fixed, and they rub against other parts during rotation; in addition, the loose stator and rotor cores and uneven air gaps can also cause abnormal noise.
Q: What are the precautions for ultra high efficiency explosion proof motor when installing?
When installing ultra high efficiency explosion proof motor, choose a suitable installation location to ensure good ventilation and stay away from flammable and explosive items; the installation foundation should be firm to prevent vibration and displacement during motor operation; the wiring must be strictly carried out in accordance with explosion-proof requirements to ensure that the junction box is well sealed to prevent external flammable and explosive gases from entering the motor.
Q: What is the reason for the sudden shutdown of the ultra high efficiency explosion proof motor during operation?
The sudden shutdown of the ultra high efficiency explosion proof motor during operation may be due to overload protection action, the motor is overloaded for a long time, and the thermal relay or other protection devices trigger the shutdown; it may also be a power failure, such as phase loss, low voltage, etc.; in addition, internal motor failures, such as winding short circuit and open circuit, can also cause the motor to stop suddenly.
