Working Principle: Discover the groundbreaking working principle of the Sanzhi Compressor, where state-of-the-art technology converges with the science of air compression to deliver unrivaled efficiency and power. Experience a revolutionary approach to air compression, where cutting-edge innovations meet precision engineering to create unparalleled power and efficiency.

In an ideal air compression process, the theoretical power required for single-stage pressure transmission equals the cumulative power necessary for multi-stage compression. Yet, in practical scenarios, actual working power escalates due to coupling transmission losses, bearing friction, and the cooling effects of liquid viscosity, among other factors. By astutely minimizing the compression ratio at each stage, superfluous power consumption can be curtailed, allowing multi-stage compression to demand less total power compared to its single-stage counterpart. This strategic approach maximizes energy efficiency and minimizes wastage, heralding a new era of sustainable and powerful performance.

The two-stage screw air compressor exemplifies engineering excellence with its dual-stage rotary screw design. Each stage comprises an active and a passive screw, driven by an external power source. The initial stage employs a low-pressure rate screw group, while the subsequent stage employs a high-pressure rate group. A sealing air film encircles each screw, compressing the gas through an impeccably seamless cycle of suction, pressurization, and exhaust, delivering extraordinary efficiency. This innovative design sets the benchmark for superior air compression performance, achieving unmatched operational standards.

First Stage Compression: During this initial phase, the two-stage screw air compressor utilizes a low-pressure rate screw group to compress gas. Gas enters the screw compression chamber through the suction valve, and as the screw rotor whirls at high speed, the gas is progressively expelled and transported to the next compression phase. This process ensures optimal compression efficiency, laying the groundwork for subsequent stages.

Second Stage Compression: In this advanced phase, the gas is channeled into a constricted screw space within the second-stage screw group, compressed under heightened temperature and pressure. The exhaust valve subsequently opens, proficiently extracting the high-pressure gas, thus completing the compression sequence. This stage epitomizes precision and efficiency, culminating the cycle with high-pressure output.

Natural air initially enters the compression system through an air filter, mingling with a minimal amount of lubricating oil inside the compression chamber. This blend undergoes initial compression to an interstage pressure level, then travels through a cooling channel, encountering abundant oil mist that significantly lowers its temperature. The cooled, compressed gas proceeds to the second-stage rotor, where it experiences further compression to achieve final exhaust pressure, culminating in a fully optimized compression cycle as the air is released through the exhaust valve. This meticulously orchestrated process results in superior air output, highlighting the compressor's exemplary performance and innovative design.

8) Internal Spray Curtain Cooling Method: With an innovative internal spray curtain cooling method, it effectively lowers compressed air temperatures, approximates isothermal compression, reduces stage pressure loss, and heightens overall compression efficiency.

9) Reduce Internal Leakage: Through two-stage compression, the compression ratio per stage is reduced, effectively mitigating internal leakage from high to low pressure, thereby enhancing volumetric efficiency.

10) Noise Reduction: The two-stage compression dramatically reduces the compression ratio, leading to a significant decrease in noise levels, particularly during unloading, creating a quieter and more enjoyable work environment.

11) Easy Maintenance and Service: Maintaining the simplicity of single-stage systems, this two-stage compressor unit, aside from the screw air end, ensures effortless maintenance and usability, delivering convenience and efficiency for users.
