This groundbreaking development not only boosts performance but also slashes energy usage, establishing Sanzhi as a leader in energy-efficient solutions.
Introducing a landmark in air compression technology: the two-stage screw air compressor. This extraordinary machine features a cutting-edge dual rotary screw system, where each stage operates a dynamic active screw propelled by an expertly crafted external power transfer. The first stage features a precisely optimized low-pressure screw assembly for maximum output, while the second stage hosts a high-pressure screw assembly. Essential to this sophisticated process are sealing air films that encase each screw, enabling the compression journey through three critical phases: smooth air intake, vigorous pressurization for unparalleled efficiency, and a perfectly executed exhaust stage.
First stage compression: The initial phase of the two-stage screw air compressor exemplifies engineering precision. A state-of-the-art low-pressure screw assembly deftly channels gas into the compression chamber via a meticulously adjusted suction valve. As the rotor spins at an impressive speed, the gas is initially compressed, laying the groundwork for enhanced compression in the next stage.
Second stage compression: Advancing to the second phase, gas is ushered into a precisely designed, tighter screw space where pressure and temperature are expertly elevated to new heights. The process culminates as the exhaust valve opens, allowing high-pressure gases to exit, thus completing the intricate compression cycle with exceptional efficiency.
The sophisticated air compression process begins as ambient air smoothly navigates through the air filter, mingling with a touch of lubricating oil in the compression chamber. This mixture experiences initial compression to intermediate pressure, followed by cooling through interaction with oil mist in the cooling channel. The cooled gas then transitions to the second-stage rotor for a secondary compression phase, reaching the desired final exhaust pressure. This meticulously orchestrated cycle concludes as the compressed gas is elegantly expelled through the exhaust valve, completing a highly efficient air compression process.
