Working Principle
In the intricate realm of air compression technology, reaching unparalleled efficiency in a single-stage system necessitates that the energy consumption closely aligns with the combined power of a multi-stage setup. Yet, real-world obstacles such as energy dissipation at couplings, bearing friction, and the thick viscosity of cooling agents often result in elevated energy demands. Multi-stage compression smartly overcomes these hurdles by diminishing the compression ratio at each stage, thereby significantly lowering the overall power requirement in contrast to single-stage mechanisms.
Introducing our groundbreaking two-stage screw air compressor, an engineering marvel that showcases a dual-stage rotary screw system. Each stage encompasses a primary and secondary screw, with the primary screw energetically propelling the secondary screw, facilitated by an external power source. The initial phase comprises a low-pressure screw assembly, succeeded by a high-pressure screw assembly in the next stage. Each screw resides within a protective air cushion, skillfully compressing gas through three critical phases: suction, pressurization, and exhaust.
First Stage Compression: The process initiates with the low-pressure screw assembly efficiently compressing the gas. As the gas is inducted into the compression chamber via a suction valve, it is meticulously compressed and then seamlessly transitions to the secondary stage, propelled by the continuous rotation of the screw rotor.
Second Stage Compression: In this crucial phase, the gas advances into a tightly sealed screw chamber, where it experiences compression under heightened temperatures and pressures. As this stage concludes, the high-pressure gases are released from the system when the exhaust valve opens, thereby completing the entire compression cycle.
The process embarks with ambient air being meticulously filtered before entering the initial compression stage, where it combines 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 substantially reduces its temperature. The cooled gas then advances to the second stage for further compression, ultimately being expelled through the exhaust valve, culminating in the complete 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 circulates through the system, it meticulously cleanses internal parts and expertly dissipates heat from both the cylinder and compressed gas. This meticulous 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.

It features a unique air end that harmonizes first-stage and second-stage compression rotors within a single casing. Driven by gears, these rotors achieve optimal linear speed for each stage, significantly enhancing compression efficiency.
8) Innovative Internal Spray Curtain Cooling:Introducing an avant-garde internal spray curtain cooling technique, delivering unmatched cooling efficiency. 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.
