Working Principle
Embark on a fascinating exploration into the forefront of air compression technology with Sanzhi's latest masterpiece! Experience unmatched energy efficiency that turns your journey into an exciting adventure, thanks to the advanced dynamics of both single-stage and multi-stage compression systems. While single-stage systems aim for efficiency similar to their multi-stage counterparts, they face challenges such as transmission losses, bearing friction, and cooling impacts from liquid viscosity, which require innovative solutions. Multi-stage compression expertly reduces the compression ratio at each stage, achieving peak efficiency by consuming significantly less power than single-stage systems. This meticulously designed approach not only enhances overall system performance but also substantially decreases energy usage, setting a revolutionary benchmark in power optimization and efficiency.
Introducing the revolutionary two-stage screw air compressor from Sanzhi (Henan) Compressor Co., Ltd. - a true marvel of modern engineering excellence. This sophisticated device boasts an ingenious dual rotary screw design, where each stage includes an active screw driving a passive counterpart through a precisely engineered external power transfer mechanism. The initial stage features a cutting-edge low-pressure screw assembly, optimized for peak performance, while the subsequent stage incorporates a high-pressure screw assembly. Central to this process are sealing air films enveloping each screw, orchestrating compression through three vital phases: seamless air intake, dynamic pressurization enhancing efficiency to unprecedented levels, and culminating in an exhaust phase executed with remarkable precision.
First Stage Compression: Witness the outset of the two-stage screw air compressor process, an epitome of engineering excellence. It begins with an innovative low-pressure screw assembly channeling gas into the compression chamber through a precisely calibrated suction valve. As the rotor spins vigorously, the gas undergoes its initial compression, setting a solid foundation for the intensified compression that follows in the next stage.
Second Stage Compression: As the gas transitions to the second stage, it enters a specially designed, more compact screw chamber. Here, pressures and temperatures are systematically elevated to exceptional levels, reaching the cycle's peak as the exhaust valve activates, releasing high-pressure gases. This marks the completion of the intricate compression cycle, executed with outstanding efficiency and precision.
The sophisticated air compression journey begins as ambient air glides smoothly through the air filter, seamlessly blending with a trace of lubricating oil within the compression chamber. This mixture undergoes initial compression to an intermediate pressure, followed by substantial cooling through interaction with oil mist in the cooling channel. The cooled gas then advances to the second-stage rotor, undergoing a secondary compression phase to achieve the desired final exhaust pressure. This intricately coordinated cycle concludes as the compressed gas is elegantly expelled through the exhaust valve, signifying the completion of a comprehensive and highly efficient air compression process.
