In the current air compressor market, frequency conversion screw air compressor, permanent magnet frequency conversion screw air compressor, two-stages compression permanent magnet frequency conversion air compressor and other series are controlled by frequency converter to achieve the adjustment of air compressor frequency, stabilize the outlet pressure of air compressor, and achieve the automatic switching of air compressor equipment frequency conversion. So, what's the role of air compressor and frequency converter?

Plus the function of frequency converter

1. The air compressor is generally selected according to the actual demand for cooling capacity under design conditions. Generally, the compressor operates throughout the year.

It crosses the two extreme weather conditions of winter and summer, so it faces a relatively complex external environment, and it is inevitable that there is a gap between the actual working conditions and the design scheme a certain deviation, so the compressor power will have an appropriate margin.

2. At present, the energy regulation of air compressor mainly includes intermittent control operation, suction regulation, cylinder unloading, bypass regulation and stepless change speed regulation and other types. Intermittent operation of air compressor is a common operation mode. When the ambient temperature is higher than the set temperature, the compressor will start.

When the ambient temperature drops below the set temperature during dynamic operation, the compressor will stop working. This mode of operation is suitable for ambient temperature comparison.

Stable and light load, but the ambient temperature is not constant at any time during actual use. Extreme weather and under complex working environment, various production activities will cause cooling load changes, frequent temperature changes, and frequent engine start and stop, which will cause large energy waste, but also very easy to wear machine parts.

3. The instantaneous current of the generator will spread all over the power grid, increasing the fluctuation of the power grid, and the service life of the compressor will also be affected. Therefore, frequency conversion technology.

The technology has also been used more in air compressors.

4. Under a certain working condition, the cooling capacity of the compressor is proportional to the mass flow. The basic idea of variable frequency regulation is to change the compressor motor speed is used to adjust the mass flow, thus changing the refrigeration capacity of the total unit.

Therefore, it is not difficult to see that the frequency of the air compressor can be effectively adjusted by the frequency converter, whether it is subjectively or objectively, it is very worthwhile. It not only saves resources to a certain extent, but also improves the air compressor the working efficiency of the system can bring more benefits to the enterprise.
