permanent magnet variable frequency air compressor advantage

  1. German BAOSI original air end, screw drive air compressor using the most advanced 5:6 asymmetric line.
  • The main rotor of the screw rotor is five teeth, the secondary rotor is six teeth, the rotor section is asymmetrical, the tooth profile and the profile curve are optimized. The profile curve of the profile has only four segments, and the area of the leakage triangle is greatly reduced. It is 1/10 of the area of the symmetrical line leakage triangle, which significantly improves the compression efficiency of the screw drive air compressor.
  • The curve of the component of the screw rotor is no longer a bit, straight line and cyclonic. The curves of arc, ellipse and parabola are used to improve the rotor tooth surface from “line” sealing to “belt” sealing, which obviously improves the sealing effect. Conducive to the formation of lubricating oil film and reduce tooth surface wear.
  • The difference between the teeth of the screw rotor is small, and the return loss is reduced. Compared with the tooth profile of the first two generations of the screw rotor – four pairs of six teeth, the thermal efficiency is increased by 10-12%.

permanent magnet variable frequency air compressor features

First, the air pressure is stable Because the frequency conversion screw drive air compressor utilizes the step-less speed regulation characteristics of the frequency converter, it can be started gently through the PID regulator inside the controller or the frequency converter; Quickly adjust the response. 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 Because the invert itself contains the function of the soft starter, the starting current is within 1.2 times of the rated current, and the starting frequency is generally 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,screw drive air compressor variable flow control power frequency drive air compressor can only work in one exhaust volume, the variable frequency air compressor can work in a wider range of exhaust. 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 air compressor can be automatically dormant, which greatly reduces the energy loss. Optimized control strategies can further improve energy savings.

Fourth, screw drive air compressor AC power supply voltage adaptability is better due to the over-modulation technology used by the invert, when the AC power supply voltage is slightly lower, it can still output enough torque to drive the motor to work; when the voltage is slightly higher, it will not cause the output to the motor. The voltage is too high. For self-generating applications, the variable frequency drive can show its advantages.
