Product Description

Product Structure

 

Internal Structure Frontside: Behold the front view of our remarkable compressor, where each component is a masterpiece of precision engineering. Meticulously organized, these elements converge to deliver performance that defies expectations. The sleek, modern design and groundbreaking configurations epitomize cutting-edge air compression technology, setting a new benchmark for efficiency and innovation.

Internal Structure Backside: The rear view uncovers a harmonious blend of robust components, masterfully engineered for enduring reliability and streamlined maintenance. This perspective highlights the strategic configuration and integrated systems that underpin the compressor's exceptional functionality and durability, ensuring seamless operation and longevity.


Working Principle: Delve into the sophisticated engineering of the Sanzhi compressor, where advanced principles coalesce to orchestrate a seamless and efficient compression process. This intricate synthesis of technology and innovation ensures that each operational phase is executed with unparalleled precision, optimizing performance and amplifying efficiency to new heights.

In the intricate domain of air compression technology, achieving the delicate balance where single-stage transmission power harmonizes with multi-stage compression power presents a formidable challenge. Real-world factors such as coupling power loss, bearing friction, and increased liquid viscosity cooling contribute to higher power consumption. To combat this, strategically reducing the compression ratio at each stage emerges as a pivotal solution. This approach guarantees that the energy demand for multi-stage compression remains below that of a single-stage system, thereby elevating performance and curtailing energy waste efficiently.

Introducing our groundbreaking two-stage screw air compressor, a marvel of modern engineering featuring dual rotary screw compressors with both active and passive screw dynamics. The active screw, propelled by external transmission, energizes the passive screw, fostering a dynamic synergy. This operation commences with a low-pressure rate screw group and progresses to an enhanced high-pressure rate configuration. Each screw, enveloped in a sealing air film, augments the rotational process, propelling efficient gas compression through a flawless cycle of suction, pressurization, and exhaust, delivering maximum efficiency and exceptional performance.

First stage compression: In this crucial initial phase, the two-stage screw air compressor engages a low-pressure rate screw group to effectively compress gas. Upon entering the screw compression chamber via the suction valve, the rapid rotation of the high-speed screw rotor compresses and directs the gas towards the subsequent stage, laying a robust foundation for efficient compression.

Second stage compression: In this advanced stage, the gas navigates into a more confined screw space, undergoing heightened temperature and pressure conditions. As compression reaches its zenith, the exhaust valve is activated, meticulously releasing high-pressure gas while ensuring the system maintains peak efficiency and seamless operation.

The journey commences with natural air, expertly filtered and introduced into the first compression stage, where it combines with a minute quantity of lubricating oil in the compression chamber. This mixture is compressed to interstage pressure and then traverses through a cooling channel, where it interacts with a rich oil mist, dramatically reducing its temperature. The cooled, compressed gas then progresses to the second-stage rotor for further compression, achieving the final exhaust pressure. Culminating its precisely managed journey, the gas exits through the exhaust valve, concluding a meticulously orchestrated compression process that guarantees optimal performance.
