Working Principle
In the complex and dynamic universe of air compression, achieving peak efficiency in single-stage compression mandates that the energy expended equates to the combined force of multi-stage compression. However, in practice, several elements such as energy loss at couplings, bearing friction, and the viscosity of cooling fluids frequently escalate energy consumption. Through the strategic reduction of the compression ratio at each subsequent stage, multi-stage compression smartly mitigates these inefficiencies, culminating in a significantly lowered total power requirement when compared to single-stage systems.
Introducing our groundbreaking two-stage screw air compressor, brilliantly engineered with a dual-stage rotary screw setup. Each stage comprises a principal and auxiliary screw, wherein the principal screw energetically propels the auxiliary screw through an external power source. The first stage features a low-pressure screw ensemble, whereas the second stage exhibits a high-pressure screw ensemble. Each screw is encased by a protective air cushion, expertly compressing the gas across three vital phases: suction, pressurization, and exhaust.
First Stage Compression: The sequence initiates with the low-pressure screw assembly efficiently compressing the gas. As gas enters the compression chamber via a suction valve, it undergoes gradual compression and then transitions to the second stage, propelled by the continuous rotation of the screw rotor.
Second Stage Compression: At this stage, the gas is transferred into a confined screw chamber, undergoing compression under elevated temperatures and pressures. As this phase concludes, the high-pressure gases are released from the system as the exhaust valve opens, thereby completing the compression cycle.
The process begins with ambient air being meticulously filtered prior to entering the initial compression stage, where it merges with a minimal quantity of lubricating oil. This blend is compressed to an interstage pressure and traverses a cooling conduit, encountering a significant oil mist that substantially decreases its temperature. The cooled gas then advances to the second stage for further compression, ultimately being expelled through the exhaust valve, thus fulfilling 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 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.

This method substantially reduces compressed air temperature, aligning closely with isothermal compression and diminishing pressure loss between stages, thereby augmenting compression efficiency.
9) Minimized Internal Leakage:Our pioneering two-stage compression technique lowers the compression ratio for each stage, thereby minimizing internal leakage from high to low-pressure ends and significantly boosting volumetric efficiency.
10) Noise Reduction:The innovative two-stage compression design significantly reduces the compression ratio, resulting in a marked decrease in operational noise, especially during unloading phases.
11) Simplified Maintenance and Service:In addition to the advanced screw air end, our two-stage compressor unit maintains similar systems and structures to single-stage compressors, ensuring straightforward maintenance and ultimate user convenience.
