Working Principle
At the forefront of air compression innovation, Sanzhi (Henan) Compressor Co., Ltd. boldly redefines efficiency benchmarks in air compression technology. With an astute balance between single-stage and multi-stage systems, Sanzhi expertly minimizes real-world inefficiencies like transmission power losses, bearing friction, and viscosity-related cooling that usually demand additional energy. Through precise optimization of compression ratios at each stage, Sanzhi's multi-stage systems exemplify remarkable efficiency, requiring significantly less power than single-stage systems. This groundbreaking achievement enhances system performance and significantly curtails unnecessary energy consumption, setting a new standard in power efficiency.
Introducing the revolutionary two-stage screw air compressor-an epitome of modern engineering prowess. This remarkable machine boasts an innovative dual rotary screw design, each stage featuring a dynamic active screw that drives a passive screw via a meticulously crafted external power transfer system. The first stage boasts a low-pressure screw assembly fine-tuned for optimal performance, while the second stage contains a high-pressure screw assembly. At the heart of this advanced process are sealing air films around each screw, orchestrating the compression journey through three essential stages: effortless air intake, dynamic pressurization elevating efficiency to new heights, and a flawless exhaust phase executed with remarkable precision.
First stage compression: The commencement of the two-stage screw air compressor's operation showcases engineering sophistication. A state-of-the-art low-pressure screw assembly adeptly directs gas into the compression chamber through a precisely engineered suction valve. As the rotor spins at high speed, the gas undergoes initial compression, priming it for intensified compression in the subsequent stage.
Second stage compression: In this phase, the gas transitions into a meticulously designed, more compact screw space, where pressure and temperature are elevated to extraordinary levels. The process reaches its peak as the exhaust valve opens, releasing high-pressure gases and completing the intricate compression cycle with exceptional efficiency.
The exquisite air compression process begins as ambient air effortlessly enters through the air filter, encountering a touch of lubricating oil within the compression chamber. This blend undergoes initial compression to intermediate pressure, followed by thorough cooling through interaction with oil mist in the cooling channel. The cooled gas then progresses to the second-stage rotor for 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 culmination of a comprehensive and highly efficient air compression process.
