The reason of screw air compressor 25 hp motor easily heat up

25hp screw air compressor motor is an indispensable power provider in people’s production and life. In the process of use, many air compressor motors have a very heat phenomenon. Why screw air compressor 25 hp motor easily heat up? The following KINGBULL 18.5kw air compressor factory will introduce you to two reasons.

The 25hp screw air compressor bearing work is not normal, it must cause the motor to heat, the bearing work is normal can be judged by hearing and temperature experience.

The bearing end can be detected by hand or thermometer to determine whether the temperature is within the normal range. the bearing rod (copper rod) can also be used to contact the bearing box. If the impact sound is heard, it means that there may be one or several balls crushed. If heard Beep, indicating that the bearing’s lubricating oil is insufficient. The motor should be replaced with grease for about 3,000 hours to 5,000 hours.

The power supply voltage is high, the excitation current increases, and the motor will overheat

Excessive voltage can jeopardize motor insulation and put it at risk of breakdown. When the power supply voltage is too low, the electromagnetic torque will decrease. If the load torque is not reduced, the rotor rotation number is too low. At this time, the increase of the slip rate will cause the motor to be overloaded and generate heat. And the long-term overload will affect the life of the motor. When the three-phase voltage is asymmetrical, that is, when the voltage of one phase is high or low. It will cause the current of a certain phase to be too large, the motor will heat up. And at the same time, the torque will be “beep” when the torque is reduced. And the winding will be damaged if the time is long.

In short, whether the voltage is too high, too low or the voltage is asymmetrical will increase the current. The motor will heat up and damage the motor. Therefore, according to national standards, the motor power supply voltage should not change by more than ±5% of the rated value. And the motor output power can be maintained at the rated value. The motor supply voltage must not exceed ±10% of the rated value. The difference between the three-phase supply voltage should not exceed ±5% of the rated value.
