Working Principle
At the forefront of groundbreaking air compression technologies, Sanzhi (Henan) Compressor Co., Ltd. has emerged as a vanguard, redefining benchmarks for extraordinary efficiency in air compression. Seamlessly integrating the advantages of both single-stage and multi-stage systems, Sanzhi adeptly overcomes obstacles like transmission power losses, bearing friction, and viscosity-related cooling, which typically require additional energy. By meticulously fine-tuning compression ratios at every stage, Sanzhi's multi-stage systems showcase unmatched efficiency, demanding substantially less power than their single-stage equivalents. This groundbreaking innovation not only amplifies system performance but also dramatically reduces energy consumption, positioning Sanzhi as a pioneer in power-efficient solutions.
Introducing the revolutionary two-stage screw air compressor-a testament to modern engineering brilliance. This remarkable creation features an advanced dual rotary screw mechanism, with each stage incorporating a dynamic active screw that drives a passive screw through an expertly engineered external power transfer system. The initial stage features a meticulously calibrated low-pressure screw assembly optimized for maximum output, while the subsequent stage accommodates a high-pressure screw assembly. Integral to this sophisticated process are sealing air films encircling each screw, facilitating the compression journey through three essential phases: seamless air intake, vigorous pressurization that elevates efficiency to unprecedented heights, and a concluding exhaust stage executed with exquisite precision.
First stage compression: The inaugural phase of the two-stage screw air compressor's operation exemplifies engineering sophistication. An advanced low-pressure screw assembly deftly channels gas into the compression chamber through a precisely calibrated suction valve. As the rotor spins at an impressive speed, the gas undergoes initial compression, laying the groundwork for enhanced compression in the subsequent stage.
Second stage compression: Advancing to the second phase, gas is guided into a meticulously designed, more compact screw space where pressure and temperature are expertly elevated to extraordinary levels. The process culminates as the exhaust valve opens, allowing the high-pressure gases to exit, thereby completing the intricate compression cycle with unparalleled efficiency.
The advanced air compression process begins as ambient air seamlessly flows through the air filter, merging with a touch 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 advances to the second-stage rotor, where it experiences a secondary compression phase, achieving the desired final exhaust pressure. This expertly orchestrated cycle concludes as the compressed gas is elegantly expelled through the exhaust valve, marking the completion of a comprehensive and highly efficient air compression process.
