Oil-free air compressor is an efficient and hygienic compressed air equipment, and its motor heating problem is an important aspect of user concern. In this paper, the causes, influencing factors and solutions of heating of oil-free air compressor will be introduced in detail.
1. Oil-free air compressor heating reasons:
The main reason for the heating of oil-free air compressor is that the loss conductance during the conversion process mainly has the following aspects:
- Resistance loss inside the motor: the coil, winding and other components inside the motor will produce a certain resistance, and there will be a certain loss when the current flows through, which leads to the motor heating.
Mechanical friction loss: The mechanical friction between the motor rotor and the bearing will generate heat, especially at high speed rotation, the friction loss will be more obvious.
- Core hysteresis loss: The motor core will produce hysteresis when the magnetic field changes, so that the molecules inside the core are rapidly oriented, this process will produce loss and lead to heating.
Copper loss: The copper wire in the motor coil will generate a certain amount of heat due to resistance.
- Poor ventilation: oil-free air compressor may be due to poor ventilation, resulting in poor heat dissipation, and then cause heating problems.
2. Influencing factors of heating without air compressor:
The degree of heating of oil-free air compressors is affected by a variety of factors, including:
- Motor power: The greater the power, the more serious the heating problem may be.
- Working load: the heavier the working load, the more obvious the motor heating.
- Use ambient temperature: the higher the ambient temperature, the more difficult the motor heat dissipation, the more serious the heating problem.
- Ventilation: Poor ventilation will lead to poor heat dissipation, and then cause motor heating problems.
- Equipment maintenance: Regular cleaning, maintenance of equipment, maintain good working condition, can effectively reduce the motor heating problem.
3. The method to solve the heating of oil-free air compressor:
For the heating problem of oil-free air compressor, the following measures can be taken to solve it:
- Optimization of equipment selection: In the purchase of oil-free air compressor, choose the appropriate power according to the actual demand to avoid excessive design, thereby reducing the occurrence of motor heating problems.
- Strengthen ventilation and heat dissipation: In the design and installation of oil-free air compressors, vents and heat dissipation equipment should be rationally arranged to ensure good ventilation and heat dissipation effect.
- Regular maintenance of equipment: regularly clean, lubricate and maintain the oil-free air compressor to keep the equipment in good working condition and reduce the occurrence of heating problems.
- Control the work load: reasonable arrangement of the work load, to avoid long-term high load operation, reduce the motor heating problem.
- Improve equipment efficiency: By improving the design, improve the efficiency of the equipment, reduce the loss during the conversion process, thereby reducing the motor heating problem.
In summary, the heating problem of the oil-free air compressor is caused by the loss during the conversion process, and its degree is affected by a variety of factors. In order to solve the problem of motor heating, the occurrence of motor heating can be reduced by optimizing equipment selection, strengthening ventilation and heat dissipation, regularly maintaining equipment, controlling workload and improving equipment efficiency. To maintain the good working condition of the equipment, in order to ensure the efficient and stable operation of oil-free air compressor.
