The frequency conversion air compressor is an air compressor that uses a frequency converter to control the frequency of the motor. In layman's terms, it means that during the operation of the screw air compressor, if the air consumption fluctuates, and the terminal air consumption is sometimes more and sometimes less, then at this time, the frequency converter of the variable frequency air compressor will play a role to adjust the motor. Rotate speed, to adjust the motor current, so as to achieve the purpose of power saving, and finally realized how much compressed air is used, how much compressed air is produced.
Main effect:
1. Energy saving: the overall energy saving is more than 20%
Energy saving during loading: After the air compressor is converted to frequency conversion, the pressure is always maintained at the required set working pressure, which can be reduced by 10% compared with before the modification. According to the power consumption formula, it can save energy by 10% after the modification.
Energy saving during unloading: The energy consumed by the motor during unloading operation is about 40% of that during loading and unloading. Calculated according to the average unloading time of about a quarter, this item can save about 10% of energy.
2. Small starting current, no impact on the power grid
The frequency converter can make the current rise smoothly when the motor is started and loaded without any impact; it can make the motor realize soft stop, avoid the harm caused by the reverse current, and help to prolong the service life of the equipment.
3. Stable output pressure
After the frequency conversion control system is adopted, the pressure of the gas in the gas supply pipeline can be monitored in real time, so that the pressure of the gas in the gas supply pipeline can be kept constant, and the production efficiency and product quality can be improved.
4. Less equipment maintenance
The starting current of the air compressor with frequency conversion is small, less than 2 times the rated current. The loading and unloading valve does not need to be repeatedly operated. The frequency conversion air compressor automatically adjusts the motor speed according to the air consumption. The operating frequency is low, the speed is slow, the bearing wear is small, and the service life of the equipment is extended. Maintenance The workload becomes smaller.
5. Low noise
The frequency conversion provides energy according to the needs of gas consumption, without too much energy loss, the motor running frequency is low, and the mechanical rotation noise is therefore reduced. Due to the frequency conversion to adjust the motor speed, there is no need to repeatedly load and unload, and the noise of frequent loading and unloading is also gone. , continuous pressurization, the noise produced by unstable air pressure can also disappear. In short, after adopting the frequency conversion constant pressure control system, not only can the service life of the compressor be extended, but also the purpose of constant pressure gas supply can be realized, and the production efficiency and product quality can be improved.
