Working Principle
At the forefront of air compression innovation, Sanzhi (Henan) Compressor Co., Ltd. proudly stands as an industry leader, redefining efficiency standards. By seamlessly integrating the unique benefits of both single-stage and multi-stage systems, Sanzhi adeptly overcomes common challenges such as transmission power losses, bearing friction, and cooling issues related to viscosity, which typically result in higher energy consumption. Through meticulous optimization of the compression ratios at each stage, Sanzhi's multi-stage systems deliver unparalleled efficiency, requiring significantly less power compared to traditional single-stage systems. This groundbreaking innovation not only enhances overall system performance but also dramatically reduces energy consumption, further cementing Sanzhi's position as a pioneer in power-efficient solutions.
Introducing the innovative two-stage screw air compressor, a true testament to modern engineering excellence. This remarkable device features an advanced dual rotary screw mechanism. Each phase contains a dynamic active screw that drives a passive screw through a precisely designed external power transfer system. The initial phase includes a finely tuned low-pressure screw assembly optimized for peak performance, while the subsequent phase accommodates a high-pressure screw assembly. Central to this sophisticated process are sealing air films encasing each screw, facilitating the compression journey through three critical stages: smooth air intake, vigorous pressurization that heightens efficiency to unprecedented levels, and an exhaust stage completed with unmatched precision.
First stage compression: The initiation of the two-stage screw air compressor's operation embodies engineering excellence. A sophisticated low-pressure screw assembly expertly channels gas into the compression chamber through a meticulously calibrated suction valve. As the rotor spins with impressive velocity, the gas undergoes initial compression, laying the foundation for enhanced compression in the subsequent stage.
Second stage compression: Progressing to the second phase, gas transitions into a meticulously designed, more confined screw space, where both pressure and temperature are expertly elevated to remarkable levels. The process reaches its culmination as the exhaust valve opens, allowing the high-pressure gases to exit, thereby completing the intricate compression cycle with unprecedented efficiency.
The sophisticated air compression process commences as ambient air smoothly flows through the air filter, blending with a trace of lubricating oil within the compression chamber. This mixture undergoes an initial compression to intermediate pressure, followed by substantial cooling through interaction with the oil mist in the cooling channel. The cooled gas then moves to the second-stage rotor, where it undergoes a secondary compression phase, achieving the desired final exhaust pressure. This expertly orchestrated cycle concludes as the compressed gas is elegantly discharged through the exhaust valve, marking the end of a comprehensive and highly efficient air compression process.
