Working Principle
In the cutting-edge realm of air compression, the pursuit of supreme efficiency unfolds in a remarkable interplay between single-stage and multi-stage compression systems. Ideally, the energy requirements for single-stage operations should align perfectly with those of their multi-stage counterparts. However, real-world conditions present additional energy demands due to factors like transmission power losses, friction in bearings, and cooling effects from liquid viscosity. By optimizing the compression ratio at each stage, multi-stage compression proves to be the pinnacle of efficiency, demanding significantly less power than single-stage systems. This innovation not only enhances overall system performance but also slashes unnecessary energy consumption, setting a new standard in power optimization.
Presenting the revolutionary two-stage screw air compressor, a masterpiece of modern engineering brilliance. This advanced machine features a sophisticated dual rotary screw mechanism; each stage consists of an active screw driving a passive screw through a meticulously designed external power transfer system. The first stage is equipped with a low-pressure screw assembly, optimized for peak performance, while the second stage is crafted with a high-pressure screw assembly. Essential to this process are sealing air films around each screw, guiding the compression journey through three crucial phases: seamless air intake, dynamic pressurization boosting efficiency to new heights, and the final exhaust phase, completing the cycle with unmatched precision.
First stage compression: The start of the two-stage screw air compressor's operation showcases engineering excellence. An extremely advanced low-pressure screw assembly leads, drawing gas into the compression chamber through a precisely designed suction valve. As the rotor spins at an impressive speed, the gas undergoes initial compression, setting the foundation for further compression in the next phase.
Second stage compression: As the process advances into the second stage, the gas enters a uniquely crafted, more confined screw space, where pressures and temperatures are meticulously elevated to unmatched levels. This operation reaches a pivotal point when the exhaust valve opens, allowing the high-pressure gases to exit the system, thus completing the sophisticated compression cycle with unparalleled efficiency.
The refined air compression journey begins with ambient air smoothly flowing through the air filter, blending with a touch of lubricating oil within the compression chamber. This mixture undergoes initial compression to intermediate pressure, then significant cooling through interaction with oil mist in the cooling channel. The cooled gas proceeds to the second-stage rotor, experiencing a secondary compression phase, achieving the desired final exhaust pressure. This expertly orchestrated cycle culminates with the elegant release of compressed gas through the exhaust valve, marking the completion of an efficient air compression process.
