Working Principle: Explore the complex engineering of the Sanzhi compressor, where state-of-the-art principles harmonize to create a smooth and efficient compression process. This sophisticated blend of technology and innovation guarantees that each operational phase is executed with precision, optimizing performance and maximizing efficiency.

In the realm of air compression technology, achieving the perfect equilibrium where single-stage transmission power aligns with multi-stage compression power is challenging. Real-world factors like coupling power loss, bearing friction, and increased liquid viscosity cooling exacerbate power consumption. To address this, reducing the compression ratio at each stage is a strategic solution. This approach ensures that the energy demand for multi-stage compression stays lower than that of a single-stage system, thus enhancing performance and minimizing energy waste.

Introducing an advanced two-stage screw air compressor, featuring innovative dual rotary screw compressors, each with active and passive screws. The active screw, driven by external transmission, energizes the passive screw, creating a dynamic synergy. The process begins with a low-pressure rate screw group, advancing to a high-pressure rate configuration in the next stage. Each screw is enveloped by a sealing air film that enhances the rotational process, promoting efficient gas compression through an immaculate cycle of suction, pressurization, and exhaust, thereby ensuring maximum efficiency and outstanding performance.

First stage compression: In this pivotal initial phase, the two-stage screw air compressor employs a low-pressure rate screw group to compress the gas. As gas enters the screw compression chamber via the suction valve, the swift rotation of the high-speed screw rotor compresses and propels the gas towards the second stage, establishing a solid foundation for efficient compression.

Second stage compression: In the second stage, the gas encounters a more constricted screw space, where it experiences increased temperature and pressure. As compression culminates, the exhaust valve activates, skillfully releasing high-pressure gas while ensuring the system retains optimal efficiency.

The journey begins with natural air, filtered and drawn into the first compression stage, where it mingles with a trace amount of lubricating oil in the compression chamber. This blend is compressed to interstage pressure and then passes through a cooling channel, interacting with a rich oil mist, significantly lowering its temperature. The cooled, compressed gas advances to the second-stage rotor for further compression, reaching the final exhaust pressure. Completing its expertly orchestrated journey, the gas exits through the exhaust valve, marking the end of a meticulously managed compression process.
