Working Principle

In an ideal air compression process, the power required for single-stage pressure transmission is equivalent to the sum needed for multi-stage compression. However, in real-world applications, actual working power increases due to various inefficiencies such as coupling transmission power loss, bearing friction, and liquid viscosity cooling effects. By reducing the compression ratio at each stage, the total power required for multi-stage compression can be made less than that for single-stage compression, effectively minimizing these losses.

The two-stage screw air compressor consists of a two-stage rotary screw mechanism. Each stage features an active and a passive screw, with the active screw driving the passive screw through an external power transmission device. The first stage employs a low-pressure rate screw group, while the second stage uses a high-pressure rate screw group. Each screw is encased in a sealing air film. As they rotate, the gas is compressed through three stages: suction, pressurization, and exhaust.

First Stage Compression: The initial stage utilizes a low-pressure rate screw group, compressing the gas between them. Gas enters the screw compression chamber via the suction valve. Under the high-speed rotation of the screw rotor, the gas is progressively squeezed out and transferred to the second stage.

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

Natural air is filtered before entering the first stage of compression, where it mixes with a small amount of lubricating oil in the compression chamber. This mixture is compressed to the interstage pressure. The compressed gas then passes through a cooling channel, where it contacts a large amount of oil mist, significantly lowering its temperature. The cooled gas enters the second-stage rotor, undergoes further compression, and is ultimately expelled through the exhaust valve to complete the entire compression process.

Water-cooled compressors leverage the power of water as a cooling medium. As the cooling water circulates through the air compressor, it not only enhances lubrication by cleaning internal components but also extends the life of friction-wearing parts. During compressor operation, the cooling water efficiently dissipates heat from the cylinder and compressed gas, significantly reducing exhaust temperature and power consumption, thereby lowering operational costs. However, attention must be given to the potential scaling issues within the water cooling system.

1) Superior Efficiency of PM Motor: Our permanent magnet motor features a broader constant torque and weak magnetic range. Its efficiency is 20-30% higher than that of traditional motors. Remarkably, when operating away from the rated frequency, its efficiency remains consistent, ensuring unparalleled motor performance.

2) Maintenance-Free Motor:Designed with no internal bearings, the permanent magnet motor eliminates the need for costly maintenance and bearing replacements.

3) Integrated Frequency Converter:Utilizing China's premier frequency system, this unit offers an extensive speed regulation range and high precision. It adjusts according to the user's actual gas demand, resulting in impressive energy-saving benefits for the air compressor.

4) Zero Transmission Loss:The permanent magnet motor and compressor feature an integrated shaft structure, directly connected and more compact. With no coupling or other transmission parts, transmission efficiency is perfected at 100%.

5) Variable Frequency and Soft Start:This motor achieves variable frequency start and soft start, significantly reducing the impact on power grid equipment and preventing damage to electrical components.

6) Enhanced Energy Efficiency:With a frequency conversion range from 25% to 100% (compared to the ordinary range of 50% to 100%), this system offers over 30% energy savings compared to fixed speed compressors. Compared to standard variable frequency compressors, it saves approximately 5% more energy. Greater fluctuations in system gas consumption amplify these energy-saving effects.

7) Unique Two-Stage Compression Air End:The two-stage compression screw machine boasts a uniquely designed air end. It integrates both first-stage and second-stage compression rotors within a single casing, rotating them through gears to achieve optimal linear speed for each stage, thereby enhancing compression efficiency.

8) Innovative Internal Spray Curtain Cooling:Our system employs an advanced internal spray curtain cooling method, delivering superior cooling performance. It significantly lowers the temperature of compressed air, approximating isothermal compression, and reduces pressure loss between stages to improve compression efficiency.

9) Minimized Internal Leakage:Adopting two-stage compression lowers the compression ratio of each stage, reducing internal leakage from high-pressure to low-pressure ends, thereby boosting volumetric efficiency.
 
10) Noise Reduction:Two-stage compression mechanisms lower the compression ratio, dramatically reducing operational noise, especially during unloading.

11) Simplified Maintenance and Service:The two-stage compressor unit, aside from the screw air end, retains similar systems and structures to single-stage compressors, ensuring ease of maintenance and user convenience.
