Product Description

Product Structure

 

Internal Structure Frontside: Behold the front facade of our compressor, where an intricate dance of precision-engineered components manifests. Each element is meticulously positioned to enhance performance to unrivaled heights. This view encapsulates the streamlined design and avant-garde configurations that propel the compressor's extraordinary efficiency.

Internal Structure Backside: Witness the rear view, where our compressor unfolds a perfect symphony of robust elements crafted for enduring reliability and ease of maintenance. From this angle, the thoughtful design and integrated systems shine, underpinning the compressor's flawless functionality and longevity.


Working Principle: Immerse yourself in the artful mechanics of the Sanzhi compressor, where state-of-the-art engineering principles unite to orchestrate a smooth, efficient compression journey. This masterful blend of technology and innovation ensures each operational phase is executed with unmatched precision, amplifying both performance and efficiency.

In the grand realm of air compression technology, the quest for the perfect equilibrium-where the power for single-stage pressure transmission seamlessly matches the cumulative power of multi-stage compression-poses a formidable challenge. Real-world hurdles like power loss via coupling, bearing friction, and the higher viscosity of cooling liquids elevate actual power consumption. To address this, minimizing the compression ratio at each stage emerges as a strategic maneuver. This approach ensures multi-stage compression demands less energy than single-stage systems, thus enhancing efficiency and reducing energy waste.

Introducing a state-of-the-art two-stage screw air compressor, marked by its innovative design featuring dual rotary screw compressors. Each bears an active and a passive screw. The active screw, driven by an external transmission, sets the passive screw into motion, creating a dynamic synergy. The process begins with a low-pressure screw group, advancing to a high-pressure setup in the subsequent stage. Every screw is wrapped in a sealing air film, amplifying the rotational cycle, thereby ensuring efficient gas compression through a flawless cycle of suction, pressurization, and exhaust, guaranteeing peak efficiency and remarkable performance.

First stage compression: In this pivotal phase, the two-stage screw air compressor skillfully employs a low-pressure screw group to start gas compression. As gas flows into the screw compression chamber through the suction valve, the swift rotation of the high-speed screw rotor compresses and propels the gas toward the second stage, laying a solid groundwork for efficient compression.

Second stage compression: Transitioning to the second stage, the gas enters a more constricted screw space, experiencing raised temperature and pressure. As the compression concludes, the exhaust valve activates, expertly discharging the high-pressure gas and ensuring the system operates at peak efficiency.

Commencing its journey, natural air purified by an air filter is channeled into the first compression stage, where it mingles with a touch of lubricating oil within the compression chamber. This fusion undergoes compression to interstage pressure, then moves through the cooling conduit. Here, it meets a rich oil mist, significantly reducing its temperature. The cooled, compressed gas advances to the second-stage rotor for further compression, reaching the final exhaust pressure. Completing its intricately choreographed journey, the gas exits through the exhaust valve, marking the end of a flawlessly managed compression process.
