Working Principle
Within the forefront of air compression technology, the intricate dance of achieving exceptional efficiency is played out between single-stage and multi-stage compression systems. While theoretically, the energy required for single-stage systems should match that of the multi-stage counterparts, real-world conditions show that additional energy is often required due to factors such as power transmission losses, bearing friction, and the cooling effects of liquid viscosity. By expertly reducing the compression ratio in each stage, multi-stage compression becomes a pinnacle of efficiency, requiring significantly less power than single-stage systems. This advancement not only enhances overall system performance but also significantly reduces unnecessary energy consumption, setting a new standard in power optimization.
Unveiling the groundbreaking two-stage screw air compressor, an extraordinary feat of modern engineering. This advanced machine features a state-of-the-art dual rotary screw mechanism. Each stage includes an active screw driving a passive screw through a finely engineered external power transfer system. The first stage is equipped with a low-pressure screw assembly, optimized for maximum performance, while the second stage is designed with a high-pressure screw assembly. Central to this process are sealing air films enveloping each screw, guiding the compression journey through three essential phases: seamless air intake, dynamic pressurization reaching new heights of efficiency, and the final exhaust phase completing the cycle with exceptional precision.
First stage compression: The initiation of the two-stage screw air compressor's function is a testament to engineering excellence. An exceptionally sophisticated low-pressure screw assembly takes the lead, channeling gas into the compression chamber via a precisely designed suction valve. As the rotor rotates at an impressive speed, the gas undergoes an initial compression, laying the groundwork for intensified compression in the next phase.
Second stage compression: As the process evolves into the second stage, the gas enters a specially designed, more compact screw space, where pressures and temperatures are carefully increased to unparalleled levels. The operation reaches its peak at the opening of the exhaust valve, allowing the high-pressure gases to exit the system, thereby completing the advanced compression cycle with unrivaled efficiency.
The refined pathway of air compression begins with ambient air effortlessly flowing through the air filter, merging with a hint of lubricating oil within the compression chamber. This mixture undergoes an initial compression to intermediate pressure, followed by substantial cooling as it interacts with oil mist in the cooling channel. The cooled gas then proceeds to the second-stage rotor, where it undergoes a secondary compression phase, achieving the desired final exhaust pressure. This meticulously orchestrated cycle concludes as the compressed gas is smoothly released through the exhaust valve, marking the completion of a comprehensive and efficient air compression process.
