Working Principle
Experience unparalleled efficiency with the Sanzhi 110kw Industrial Water-Cooled Two-Stage Screw Air Compressor with Variable Frequency! Our advanced multi-stage compression process intelligently reduces the compression ratio at each stage, significantly minimizing inefficiencies such as coupling power loss, bearing friction, and cooling liquid viscosity. This innovative approach guarantees superior performance with lower total power requirements, surpassing traditional single-stage compression systems.
Discover the brilliance of the Sanzhi 110kw Industrial Water-Cooled Two-Stage Screw Air Compressor, a marvel of engineering that features an innovative dual-stage rotary screw mechanism. Each stage is equipped with both active and passive screws. The active screw drives the passive screw through an external power device. The first stage utilizes a low-pressure rate screw group, while the second stage employs a high-pressure rate screw group. Encased in a sealing air film, these screws meticulously compress gas through three essential phases: suction, pressurization, and exhaust.
First Stage Compression: The process begins with the low-pressure rate screw group expertly compressing the gas. The gas enters the compression chamber via a suction valve, where it is gradually compressed and then transferred to the second stage, driven by the high-speed rotation of the screw rotor.
Second Stage Compression: In this critical phase, the gas moves into a more confined screw space, undergoing heightened compression at increased temperatures and pressures. The high-pressure gases are then efficiently expelled from the system as the exhaust valve opens, perfectly completing the compression cycle.
Our compression journey starts with natural air being meticulously filtered before it enters the first compression stage. Here, it mixes with a precise amount of lubricating oil, compressing this mixture to interstage pressure. The compressed gas then traverses through a cooling channel, encountering a substantial amount of oil mist that significantly lowers its temperature. This cooled gas then advances to the second stage for further compression, ultimately being expelled through the exhaust valve, masterfully completing the entire compression process.
Water-cooled compressors employ the unparalleled cooling power of water to provide exceptional lubrication and greatly prolong the lifespan of high-friction components. This advanced system circulates cooling water to thoroughly cleanse internal parts and dissipate heat from both the cylinder and compressed gas. The outcome is a highly efficient process that significantly reduces exhaust temperature and power consumption, resulting in considerable operational cost savings. To maintain optimal performance, it is crucial to consistently monitor and address potential scaling issues within the water cooling system.

4) Zero Transmission Loss:Boasting an integrated shaft structure that directly connects the permanent magnet motor and compressor, this design eliminates couplings and additional transmission components, achieving perfect transmission efficiency of 100%.
5) Variable Frequency and Soft Start:Our motor features variable frequency start and soft start capabilities, significantly minimizing impact on power grid equipment and protecting against potential damage to electrical components.
6) Enhanced Energy Efficiency:With a frequency conversion range from 25% to 100%-far superior to the standard 50% to 100%-our system delivers over 30% energy savings compared to fixed-speed compressors. It also conserves approximately 5% more energy than standard variable frequency compressors, with even greater savings during substantial fluctuations in system gas consumption.
7) Unique Two-Stage Compression Air End:Our two-stage compression screw machine features a specialized air end, integrating first-stage and second-stage compression rotors within a single casing. These rotors function through gears to achieve optimal linear speed for each stage, significantly enhancing compression efficiency.
8) Innovative Internal Spray Curtain Cooling:Our revolutionary internal spray curtain cooling technique offers outstanding cooling performance. It drastically reduces compressed air temperature, closely approximating isothermal compression, and minimizes pressure loss between stages, thereby boosting compression efficiency.
9) Minimized Internal Leakage:By utilizing a two-stage compression method, we reduce the compression ratio for each stage, thereby minimizing internal leakage from high-pressure to low-pressure ends and enhancing volumetric efficiency.
10) Noise Reduction:The two-stage compression design substantially lowers the compression ratio, leading to a significant reduction in operational noise, especially during unloading phases.
11) Simplified Maintenance and Service:Alongside the screw air end, our two-stage compressor unit maintains similar systems and structures to single-stage compressors, ensuring straightforward maintenance and user convenience.
