Working Principle: Immerse yourself in the sophisticated mechanics of the Sanzhi compressor, where cutting-edge engineering principles converge to forge a seamless and efficient compression process. This masterful blend of technology and innovation ensures every stage of operation executes with precision, maximizing performance and elevating efficiency to new heights.

Explore the world of air compression technology, where the quest for the ideal balance between single-stage pressure transmission power and the combined power of multi-stage compression is ever-present. Real-world challenges such as coupling power loss, bearing friction, and increased liquid viscosity cooling amplify power consumption. To address this, reducing the compression ratio at each stage stands as a strategic approach, ensuring that the energy demands of multi-stage compression are minimized compared to single-stage systems, optimizing performance and curbing energy wastage effectively.

Presenting a state-of-the-art two-stage screw air compressor, with an avant-garde design featuring dual rotary screw compressors, each embedded with an active and a passive screw. The active screw, driven by an external transmission, activates the passive screw in a powerful synergy. The process initiates with a low-pressure rate screw group, advancing to a high-pressure rate configuration in the following stage. Each screw is ensconced by a sealing air film that enhances the rotational mechanism, fostering efficient gas compression through a flawless cycle of suction, pressurization, and exhaust, ensuring peak efficiency and outstanding performance.

First stage compression: In this pivotal initial phase, the two-stage screw air compressor deftly utilizes a low-pressure rate screw group to compress the gas. As the gas is drawn into the screw compression chamber via the suction valve, the rapid rotation of the high-speed screw rotor compresses and propels it towards the second stage, laying a solid groundwork for efficient compression and setting the stage for optimal performance.

Second stage compression: Advancing to the second stage, the gas encounters a more compact screw space, where it experiences heightened temperature and pressure. As the compression process reaches its zenith, the exhaust valve activates with precision, efficiently discharging high-pressure gas and preserving the system's optimal efficiency and reliability.

As the journey begins, natural air refined by an air filter is drawn into the initial compression stage, mingling with a trace of lubricating oil within the compression chamber. This blend undergoes compression to interstage pressure and traverses the cooling channel, where it encounters a rich oil mist that significantly lowers its temperature. The cooled, compressed gas then advances to the second-stage rotor for a subsequent round of compression, achieving the final exhaust pressure. Culminating its meticulously orchestrated journey, the gas exits through the exhaust valve, marking the end of an impeccably managed and precision-controlled compression process.
