Two Stage Screw Air Compressor

The air end adopts an integrated design, which greatly simplifies the structure and has more efficient performance. Due to the use of two-stage compression, the force load of the single-stage bearing is greatly reduced, and the bearing structure selection is optimized while ensuring the bearing life, with higher efficiency and significant technical advantages.

Two-stage compression screw air compressor has low noise, low vibration and high reliability.
Two-stage compression reduces the compression ratio of each stage, reduces internal leakage, and improves volumetric efficiency
Reduce the load of the bearing, improve the life of the bearing and prolong the life of the main engine.
Low-noise design, use a large-diameter, low-speed low-noise fan
Fully enclosed mute design, more in line with international working noise standards.

Description

After the air is compressed in the first stage, the temperature of the second stage suction is reduced by strengthening the oil injection cooling, and the air is subjected to isobaric compression to reduce the compression work.
The two-stage compression adopts the equal pressure ratio to set the interstage pressure, so the compression ratio of each stage is much lower than the single-stage compression ratio, the backflow leakage between the rotors is greatly reduced, and the volumetric efficiency and adiabatic efficiency are greatly improved. Increase, correspondingly increase the compressed gas production.
Under the same power, the gas production of two-stage compression is higher than that of single-stage compression.

More Details

The pressure ratio of each stage of the two-stage compression is reduced, so the leakage of the seal between the rotors is greatly reduced, and the volumetric efficiency of the head is improved;
Unique design of the main engine, the first-stage compression unit and the second-stage compression unit are integrated in one body, driven by gears, so that the rotor of each stage of compression unit can obtain the best linear speed.
The centrifugal fan is adopted, and the cooling method is changed from forced exhaust cooling to suction cooling, which significantly reduces operating noise.
The stator coil of the permanent magnet motor and the permanent magnet rotor generate a strong electromagnetic force, which drives the motor shaft to rotate at different speeds. The motor shaft directly drives the directly connected male rotor of the host, without the efficiency loss of the intermediate transmission part, and the frequency conversion speed regulation saves energy
