Working Principle: Delve into the refined mechanics that power our compressor, where precision and innovation converge to create unmatched energy efficiency and performance.
In the sophisticated realm of air compression, achieving unparalleled efficiency within a single-stage compression demands that the energy utilized mirrors the combined strength of multi-stage compression. However, real-world challenges, such as energy loss at couplings, friction from bearings, and the viscosity of cooling fluids, often lead to elevated energy consumption. Multi-stage compression skillfully addresses these challenges by reducing the compression ratio at each stage, resulting in a significantly decreased total power requirement compared to single-stage systems.
Introducing our groundbreaking two-stage screw air compressor, an engineering marvel that showcases a dual-stage rotary screw configuration. At the heart of this innovation lies a sophisticated mechanism where each stage features a primary and secondary screw. The primary screw dynamically drives the secondary screw, bolstered by an external power source. The initial stage is equipped with a low-pressure screw assembly, followed by a high-pressure screw ensemble in the subsequent stage. Every screw is carefully encased within a protective air cushion, proficiently undertaking the gas compression through three vital phases: suction, pressurization, and exhaust.
First Stage Compression: The process begins with the low-pressure screw assembly skillfully compressing the gas. As the gas is drawn into the compression chamber via a suction valve, it is meticulously compressed and then seamlessly transitions to the second stage, driven by the continuous rotation of the screw rotor.
Second Stage Compression: In this crucial stage, the gas is transferred into a tightly sealed screw chamber, where it undergoes compression under escalated temperatures and pressures. As this stage concludes, the high-pressure gases are released from the system upon the opening of the exhaust valve, thereby completing the compression cycle.
The journey commences with ambient air being precisely filtered before entering the initial compression stage, where it merges with a minimal quantity of lubricating oil. This blend is compressed to an interstage pressure and navigates through a cooling conduit, encountering a significant oil mist that dramatically reduces its temperature. The cooled gas then advances to the second stage for further compression, eventually being expelled through the exhaust valve, culminating in the comprehensive compression sequence.
Harnessing the remarkable cooling efficacy of water, Sanzhi (Henan) Compressor Co., Ltd's water-cooled compressors ensure unparalleled lubrication and significantly prolong the lifespan of friction-prone components. As cooling water gracefully circulates through the system, it meticulously cleanses internal parts and expertly dissipates heat from both the cylinder and compressed gas. This exceptional engineering results in dramatically reduced exhaust temperatures and diminished power consumption, culminating in extraordinary savings in operational expenses. To maintain peak performance, diligent monitoring and proactive management of potential scaling issues within the water cooling system are crucial.

This method significantly lowers compressed air temperature, aligning closely with isothermal compression and reducing pressure loss between stages, thus boosting compression efficiency.
9) Minimized Internal Leakage:Our pioneering two-stage compression technique carefully reduces the compression ratio for each stage, effectively minimizing internal leakage from high to low-pressure ends, and significantly enhancing volumetric efficiency.
10) Noise Reduction:The ingenious two-stage compression design effectively lowers the compression ratio, resulting in a noticeable decrease in operational noise, particularly during unloading phases.
11) Simplified Maintenance and Service:Besides the advanced screw air end, our two-stage compressor unit preserves similar systems and structures to single-stage compressors, ensuring maintenance is straightforward and user convenience is maximized.
