Two-Stage Permanent Magnet Variable Speed Screw Compressor

Two Stage Air Compressor Element

The material of the air compressor element is 40CrA high quality alloy steel,which has

the high quality performance of wear-resisting and corrosion-resisting.

Adopting BAES rotor profile developed by BAE Group, adopting the third generation

5:6 asymmetric tooth rotor, balanced at high speeds Force, rotor tangential speed≤35m / s, the gap between the rotor to maintain 0.003INCH, the same power section air end can save energy 10-15% Self-developed isothermal curve design, improve isometric compression performance, for different oil paths to achieve interstage cooling, improve the adiabatic efficiency; by reducing the compression ratio to reduce the amount of leakage, close to the isothermal compression, compared to the single-stage compression efficiency by 13-15%

■ Due to the different voltage characteristics in China and Europe, Geso Group's technicians have exam- ined and selected domestic high-end motor manufacturers that met the Group's production requirements and standards to customize their products.

■ Ultra-low temperature rise design, air end can be stable operation in long-term lower frequency.permanent magnet selectlon of 38UH materlal, the highest working temperature up to 180 C, IE5 energy efficlency level, in the set pressure, the unit through frequency adjustment, to maintain the pressure difference within 0.1Mpa,in the long-term use of the process of smoother operation, more energy efficient!

■ The motor and fan are controlled by frequency conversion regulation, thus making the oil temperature of the air end constant and the running speed lower, and enhancing the service life of the mainframe.

■ Customized high-performance vector control frequency converter of Huichuan/ABB brand is used,the constant tempera ture of the unit is set at about 82°C, and the constant pressure accuracy is controlled at 0.01 MPA.

■ Customized frequency conversion speed control can be started at zero speed and adiusted uniformly according to the user's needs.

■ Linear acceleration, S-acceleration or automatic acceleration can be selected.
