MUT-220A Saman Two-stage Permanent Magnet Variable-frequency Screw Air Compressor With High Output Capacity

The Saman two-stage compression permanent magnet variable-frequency screw air compressor demonstrates outstanding performance in terms of high efficiency and energy savings, high-quality air output, stability, noise control, ease of maintenance, optimized energy management, and overload protection. It is an ideal air compression solution in the modern industrial sector.

The two-stage compression permanent magnet (also known as two-stage compression) screw air compressor, as its name suggests, combines the permanent magnet first-stage compression rotor and the permanent magnet second-stage compression rotor within a single casing, and they are directly driven by bevel gears. Natural air passes through the air filter and enters the first stage compression. In the compression chamber, it mixes with a small amount of lubricating oil and simultaneously compresses the mixed gas to the inter-stage pressure. The compressed gas then enters the cooling channel and comes into contact with a large amount of oil mist, thereby significantly reducing the temperature. The cooled compressed gas then enters the second-stage rotor for secondary compression, and is compressed to the final exhaust pressure. Finally, the compressed air is discharged from the compressor through the exhaust flange, completing the entire compression process. According to the principles of engineering thermodynamics, the air compressor achieves the least energy consumption during isothermal compression (when the temperature is high, the density of the gas is lower, and more energy is required for compression). Moreover, isothermal compression not only reduces the consumed energy but also lowers the temperature of the compressed gas, making the use of air compressor materials more extensive and economical, and making the operation of the air compressor more reliable. However, isothermal compression requires that the gas heat be constantly exchanged with the outside, with the gas temperature being equal to that of the outside. This is impossible to achieve in practical work. And through staged compression and intermediate cooling, it is an effective method to reduce the exhaust temperature.
