Working Principle
In an ideal air compression scenario, the power needed for single-stage pressure transmission equals the collective power required for multi-stage compression. However, in practical applications, additional power is demanded due to transmission power loss, bearing friction, and the cooling effects of liquid viscosity. By minimizing the compression ratio at each stage, the total power required for multi-stage compression can be significantly reduced compared to single-stage compression. This results in enhanced efficiency and reduced unnecessary power consumption.
The two-stage screw air compressor features an advanced dual rotary screw system. Each stage is equipped with an active and a passive screw, where the active screw drives the passive screw through an external power transmission mechanism. The first stage involves a low-pressure screw group, while the second stage utilizes a high-pressure screw group. Sealed air films around each screw facilitate the compression process, which occurs in three critical phases: suction, pressurization, and exhaust.
First Stage Compression: The initial stage in the two-stage screw air compressor employs a low-pressure screw group. Gas enters the screw compression chamber via the suction valve and is compressed as the screw rotor spins rapidly. The compressed gas is then transferred to the second stage for further compression.
Second Stage Compression: In this stage, gas enters a more confined screw space and is subjected to higher pressures and temperatures. The exhaust valve opens to expel the high-pressure gases from the system, completing the compression process.
Initially, natural air enters through the air filter and mixes with a small amount of lubricating oil in the compression chamber. This mixture is compressed to interstage pressure and is then significantly cooled by contact with oil mist in the cooling channel. The cooled gas then enters the second-stage rotor for secondary compression to the final exhaust pressure. The entire process culminates as the compressed gas is expelled through the exhaust valve, completing the air compression cycle.

The centrifugal fan, enriched with cutting-edge German technology, harnesses the power of a high-speed rotating impeller to dynamically accelerate and decelerate air. This revolutionary design enables axial air entry into the impeller, dramatically boosting motor cooling efficiency. Compared to traditional air-cooled fans, this remarkable mechanism achieves faster temperature reduction, guaranteeing continuous and uninterrupted compressor operation while significantly extending the compressor's service life.
1) High efficiency of PM motor:The permanent magnet (PM) motor features an expanded constant torque range and a wider weak magnetic range. Its efficiency surpasses regular motors by 20-30%, maintaining high efficiency even when operating away from the rated frequency. This ensures optimal performance under varying conditions, setting a new standard for motor efficiency.
2) Motor maintenance-free:Designed without internal bearings, the permanent magnet motor eliminates the costs associated with motor bearing maintenance and replacement, substantially reducing overall maintenance expenses and enhancing long-term savings.
3) Integrated frequency converter: Featuring China's premier frequency system, our compressor offers a wide speed regulation range with exceptional precision. The system intelligently adjusts to actual gas demand, delivering remarkable energy savings while optimizing operational efficiency. This seamless integration ensures your system runs at peak performance, tailored to your specific needs.
4) No transmission loss: The compressor's direct shaft connection structure with the embedded permanent magnet motor ensures a compact and efficient design. By eliminating the need for couplings and other transmission components, it achieves 100% transmission efficiency, providing unparalleled performance.
5) Variable frequency start and soft startof the motor significantly reduce impact on power grid equipment, preventing damage to electrical systems. This enhances overall system longevity, ensuring a stable and reliable power supply.
6) Reduced energy consumption: With a frequency conversion range spanning from 25% to 100% (compared to the standard 50% to 100%), our system delivers over 30% energy savings compared to fixed-speed compressors. Additionally, it provides approximately 5% more energy savings than typical variable frequency compressors, offering greater benefits for systems with fluctuating gas consumption.
7) Unique two-stage compression air end:Boasting a distinctive design, the two-stage compression screw machine integrates both the first and second-stage compression rotors within a single casing. Each rotor is individually gear-driven to achieve optimal linear speed, maximizing overall compression efficiency and delivering superior performance.
8) Internal spray curtain cooling method: Employing a high-efficiency internal spray curtain cooling technique, this method provides superior cooling effects, significantly reducing compressed air temperatures. This process achieves near-isothermal compression, minimizes pressure loss between stages, lowers the compression ratio, and enhances overall compression efficiency.
9) Reduced internal leakage:The two-stage compression system reduces the compression ratio for each stage, effectively minimizing internal leakage between high and low-pressure ends and improving volumetric efficiency. This results in a more efficient and reliable compression process.
10) Noise reduction:The reduced compression ratio in the two-stage system notably diminishes noise levels, particularly during unloading operations. This ensures a quieter working environment, enhancing workplace comfort and productivity.
11) Easy maintenance and service:Despite its advanced two-stage compression design, the system's other components and structures remain fundamentally similar to those of single-stage compressors. This ensures ease of maintenance and user convenience, providing a hassle-free experience for operators.
