When we use screw air compressors in daily life, we may encounter excessive current in the motor of the screw air compressor. What is the reason for the excessive current in the motor of the air compressor? Let's analyze it briefly below:
1. The ambient temperature of the screw air compressor is too high. Solution: Install air duct exhaust equipment on the screw air compressor;
2. The three-phase voltage of the screw air compressor motor is unstable, lacks phase, and the voltage is too low (less than 10%). Solution: Please improve the power system of the factory;
3. The temperature controller of the screw air compressor motor fails. Solution: Replace the temperature controller of the screw air compressor;
4. The overload protector of the screw air compressor fails. Solution: Replace the overload protector of the screw air compressor;
5. The contact of the starter of the screw air compressor is poor. Solution: Maintain the contact of the starter of the screw air compressor;
6. The oil-gas separator core of the screw air compressor is blocked. Treatment method: When the pressure difference between the front and rear of the oil-gas separator core of the screw air compressor is greater than 0.8-1kg/cm2, the oil-gas separator core should be replaced;
7. The screw air compressor motor bearing is not filled with oil. Treatment method: Add butter to the motor bearing;
8. The screw air compressor motor bearing is damaged. Treatment method: Replace the motor bearing;
9. The screw air compressor motor insulation is poor. Treatment method: Remove the motor for insulation reinforcement;
10. The screw air compressor motor wiring is loose. Treatment method: Re-tighten the motor wiring;
11. The air inlet of the screw air compressor is blocked. Treatment method: Clean and maintain the air inlet of the screw air compressor;
12. The air filter of the screw air compressor is blocked. Treatment method: Replace the air filter element.
