This angle reveals a thoughtful layout of integrated systems, ensuring impeccable functionality and long-lasting durability, making it a hallmark of engineering excellence.


Working Principle: Explore the refined mechanics of the Sanzhi compressor, where state-of-the-art engineering principles converge, orchestrating a flawless and efficient compression process. This sublime fusion of technology and innovation guarantees precision at every operational stage, elevating performance and efficiency to unprecedented heights.

In the realm of air compression technology, the pursuit of optimal power balance is paramount. Here, aligning the power for single-stage pressure transmission with the total multi-stage compression power is crucial yet challenging. Real-world issues like coupling power loss and bearing friction elevate power requirements. To overcome these, reducing the compression ratio per stage emerges as a strategic approach, ensuring multi-stage systems demand less energy than single-stage counterparts, thereby optimizing performance and energy efficiency.

Introducing the advanced two-stage screw air compressor, a pinnacle of modern design featuring dual rotary screw compressors, each boasting an active and passive screw. The active screw, driven by an external source, imparts motion to the passive screw, creating a dynamic synergy. The process begins with a low-pressure screw group, advancing to a high-pressure configuration in subsequent stages. This system is enveloped by a sealing air film that enhances rotation, ensuring efficient gas compression through an exquisite cycle of suction, pressurization, and exhaust, achieving maximum efficiency and unparalleled performance.

First stage compression: The initial phase of the two-stage screw air compressor harnesses a low-pressure rate screw group to compress the gas. As gas enters the compression chamber through the suction valve, the high-speed screw rotor's swift rotation compresses and drives the gas forward towards the second stage, laying a solid foundation for optimal compression.

Second stage compression: Upon reaching the second stage, the gas is subjected to a more confined screw space, experiencing intensified temperature and pressure. As compression reaches its zenith, the exhaust valve engages, expertly releasing high-pressure gas, ensuring the system's optimal efficiency is consistently maintained.

As the journey begins, natural air, purified via an air filter, is drawn into the first compression stage, blending seamlessly with a trace of lubricating oil in the chamber. This mixture is compressed to interstage pressure and navigates through the cooling channel, interacting with a rich oil mist to significantly reduce its temperature. The cooled, compressed gas then proceeds to the second-stage rotor for further compression, reaching final exhaust pressure. This meticulously orchestrated journey concludes as the gas exits through the exhaust valve, representing the culmination of an impeccably managed compression process.
