Efficient air compressors Presentation

  • First, the pressure is stable

Because the frequency conversion Efficient air compressors utilizes the steeples speed regulation characteristic of the frequency converter, the PID regulator inside the controller or the frequency converter can be smoothly started; in the occasion where the fluctuation of the gas consumption is relatively large, the response can be quickly adjusted.

The air pressure stability is exponentially increased compared to the upper and lower limit switch control of the power frequency operation.

  • Second, start without impact

Since the invert itself has the function of a soft starter, the starting current is within 1.2 times of the rated current, and the starting shock is small compared with the power frequency starting generally 6 times of the rated current. This kind of impact is not only on the grid, but also on the impact of the entire mechanical system.

  • Third, variable flow control

The power frequency driven Efficient air compressors can only work in one exhaust volume, and the variable frequency air compressor can work in a wide range of exhaust gas. The frequency converter adjusts the motor speed in real time according to the actual gas consumption to control the displacement.

When the gas consumption is low, the Efficient air compressors can be automatically dormant, which greatly reduces the energy loss. Optimized control strategies can further improve energy savings.

  • Fourth, the AC power supply voltage adaptability is better

Due to the over-modulation technology used by the invert, sufficient torque can be output when the AC power supply voltage is slightly lower to drive the motor to work; when the voltage is slightly higher, the voltage output to the motor is not high.

For self-generating applications, the variable frequency drive can show its advantages. According to the characteristics of the motor VF (the variable frequency air compressor works below the rated voltage in the energy-saving state), the effect is obvious for the site with low grid voltage.

  • Five, low noise

Most of the operating conditions of the invert system are lower than the rated speed, the main machine noise and wear are reduced, extending maintenance and service life.

If the fan is also driven by a variable frequency drive, it can significantly reduce the noise when the air compressor is working.

Efficient air compressors Working Principle

The working principle of the permanent magnet variable frequency air compressor is that the natural air enters the first stage compression through the air filter, and the compression chamber is confused with a small amount of lubricating oil, and the confusing gas is compressed to the inter-stage pressure.

The compressed gas enters the cooling passage and comes into contact with a small amount of oil mist, which greatly drops the temperature. The cooled compressed gas enters the second stage rotor, undergoes secondary compression, and is compressed to the final exhaust pressure. Finally, the compressor is discharged through the exhaust flange to complete the entire compression process.

The permanent magnet variable frequency air compressor is a twin Efficient air compressors. The working principle of twin-screw air compressor is divided into four stages: suction process, sealing and conveying process, compression and fuel injection process and exhaust process. It can compress high quality air very well. Helping companies produce and provide strong momentum.
