Working Principle

In an ideal air compression process, the power requirement for single-stage pressure transmission is equivalent to the combined power for multi-stage compression. However, in reality, the actual working power increases due to factors such as coupling power loss, bearing friction, and the cooling effect of liquid viscosity. Thus, by lowering the compression ratio at each stage, the total power needed for multi-stage compression becomes less than that for single-stage compression, effectively reducing unnecessary power consumption.

The two-stage screw air compressor features a two-stage rotary screw mechanism, with each stage containing an active and a passive screw. The active screw drives the passive screw via an external power transmission device. The first stage employs a low-pressure screw group, while the second stage uses a high-pressure screw group. Surrounding each screw is a sealing air film. As the screws rotate, gas undergoes three processes: suction, pressurization, and exhaust, thereby achieving efficient compression.

First Stage Compression: The initial stage of the two-stage screw air compressor uses a low-pressure screw group, which compresses the gas between the screws. The gas enters the screw compression chamber through the suction valve. With the high-speed rotation of the screw rotor, the gas is gradually compressed and then transferred to the second stage.

Second Stage Compression: In the second stage screw group, the gas enters a more confined screw space, where it is further compressed at higher temperatures and pressures. The exhaust valve then opens, expelling the high-pressure gas from the system.

Natural air is drawn into the first stage of compression through an air filter, where it mixes with a small amount of lubricating oil. This mixture is compressed to an intermediate pressure. The compressed gas then enters a cooling channel, where it contacts a significant amount of oil mist, substantially lowering the temperature. The cooled, compressed gas enters the second-stage rotor, undergoes further compression to the final exhaust pressure, and is finally discharged through the exhaust valve, completing the entire compression cycle.

Water-cooled compressors, leveraging water as the cooling medium, offer significant advantages. As cooling water circulates through the air compressor, it not only aids in cleaning but also enhances lubrication, thereby extending the lifespan of friction-wearing components. During operation, the cooling water absorbs heat from the cylinder and the compressed gas, effectively lowering exhaust temperature and power consumption, which in turn reduces operating costs. However, it's crucial to monitor and manage potential scaling issues in the water cooling system.

1) Outstanding Efficiency of PM Motor: Boasting a broader constant torque range and weak magnetic range, the permanent magnet motor operates with 20-30% higher efficiency compared to conventional motors. Remarkably, even when functioning away from the rated frequency, the efficiency remains consistently high, ensuring optimal performance.

2) Maintenance-Free Motor:The design of the permanent magnet motor is devoid of internal bearings, thereby eliminating the costs associated with bearing maintenance and replacement.

3) Integrated Frequency Converter:Utilizing China's premier frequency system, the converter offers a wide speed regulation range and high precision. It modulates operation based on actual gas demand, significantly enhancing the air compressor's energy efficiency.

4) Zero Transmission Loss:Thanks to the embedded integrated shaft design directly connecting the permanent magnet motor to the compressor, the structure is more compact. This eliminates couplings and other transmission parts, achieving 100% transmission efficiency.

5) Soft Variable Frequency Start:The motor's variable frequency and soft start capabilities drastically reduce impacts on power grid equipment, preventing potential damage to electrical components.

6) Enhanced Energy Conservation:With a frequency conversion range from 25% to 100% (compared to 50% to 100% in standard systems), this compressor saves over 30% more energy compared to fixed-speed models and about 5% more than conventional variable frequency compressors. Greater fluctuations in system gas consumption further amplify energy-saving effects.

7) Unique Two-Stage Compression Air End:The ingenious two-stage compression screw design houses both the first-stage and second-stage rotors within a single case, driven directly by gears. This configuration ensures optimal linear speed for each rotor stage, maximizing compression efficiency.

8) Innovative Internal Spray Curtain Cooling:By employing an energy-efficient internal spray curtain cooling method, the system delivers superior cooling. This approach significantly lowers the temperature of compressed air, nearly achieving isothermal compression, while also reducing pressure loss between stages, thus improving overall compression efficiency.

9) Minimized Internal Leakage:Adopting two-stage compression reduces the compression ratio for each stage, thereby minimizing internal leakage from high-pressure to low-pressure ends and enhancing volumetric efficiency.

10) Superior Noise Reduction:The two-stage compression method significantly lowers the compression ratio, resulting in a notable reduction in noise levels, especially the unloading noise.

11) Simplified Maintenance and Service:Apart from the screw air end, the two-stage compressor unit's systems and structures are largely similar to those of single-stage compressors, providing users with greater ease of maintenance and service.
