At present, because the actual use effect of centrifugal fans is very good, it has been widely used for ventilation, dust exhaust and cooling. However, in order to ensure the use and management of equipment, it is not only necessary to meet some basic requirements, but also because of the explosion-proof centrifugal fan. The motor is mainly operated during operation, so there is an inevitable request for the motor when it is used. What are the requirements for the motor?
1. The motor rating and performance design specifications shall not be less than 120% of the requested centrifugal fan equipment. When the motor is at full load, and the frequency innovation is ±5%, and the voltage innovation is ±10%, the motor can still operate normally without damage.
2. Under the condition of rated voltage, the motor current demand is kept within the scope of the regulation during the starting process. If a multi-phase motor is used in the fan equipment, the phase sequence should be marked on the nameplate on the junction box and the purpose of the rotation target should be marked with an arrow.
3. In some other workplaces, the motors provided in the centrifugal fan equipment are different, such as the ability to use AC, asynchronous, and air-cooled motors.
The above is the request of the explosion-proof centrifugal fan for the motor. Because the quality of the motor indirectly guarantees the effect of the equipment, when purchasing the equipment, it is necessary to see whether the motor can meet our requirements. During normal use, we need to stop inspection and maintenance on schedule to ensure that there will be no problems during use and prevent delays in the service life of the equipment.
