Working Principle
In the intricate world of air compression, achieving supreme efficiency within a single-stage compression requires that the energy used mirrors the cumulative strength of multi-stage compression. However, practical challenges such as energy loss at couplings, friction from bearings, and the viscosity of cooling fluids often lead to increased energy consumption. Multi-stage compression adeptly addresses these challenges by reducing the compression ratio at each stage, resulting in a much-reduced total power requirement compared to single-stage systems.
Presenting our revolutionary two-stage screw air compressor, a marvel of engineering featuring a dual-stage rotary screw configuration. Each stage consists of a primary and a secondary screw, where the primary screw dynamically drives the secondary screw with the aid of an external power source. The initial stage consists of a low-pressure screw assembly, while the subsequent stage boasts a high-pressure screw ensemble. Every screw is nestled within a protective air cushion, proficiently compressing the gas through three essential phases: suction, pressurization, and exhaust.
First Stage Compression: The process commences with the low-pressure screw assembly effectively compressing the gas. As the gas is drawn into the compression chamber through a suction valve, it is carefully compressed and then transitions seamlessly to the second stage, driven by the continual rotation of the screw rotor.
Second Stage Compression: In this pivotal stage, the gas is moved into a tightly bound screw chamber, where it undergoes compression under increased temperatures and pressures. As this stage wraps up, the high-pressure gases are released from the system as the exhaust valve opens, thus completing the compression cycle.
The journey begins with ambient air being precisely filtered before entering the initial compression stage, where it amalgamates with a minimal amount of lubricating oil. This mixture is compressed to an interstage pressure and travels through a cooling conduit, encountering a significant oil mist that dramatically lowers its temperature. The cooled gas then progresses to the second stage for additional compression, ultimately 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 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 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.
