Working Principle
In the enthralling realm of air compression technology, achieving ultimate efficiency in single-stage compression necessitates that power consumption precisely resembles the total exertion found in multi-stage compression frameworks. However, in practical scenarios, inefficiencies often arise, such as energy dissipation due to coupling, bearing friction, and the cooling fluid's viscosity, cumulatively elevating power demands. Ingeniously, multi-stage compression strategically diminishes the compression ratio per stage, curtailing these inefficiencies effectively and considerably reducing overall power requirements compared to single-stage compression. This sophisticated approach elegantly optimizes energy consumption and enhances performance.
Unveiling our innovative two-stage screw air compressor, a pinnacle of engineering brilliance, featuring a dual-stage rotary screw mechanism. Every stage is thoughtfully designed with an active and a passive screw. The active screw propels the passive screw via an external power source, ensuring flawless operation. The initial stage hosts a low-pressure rate screw assembly, while the subsequent stage showcases a high-pressure rate screw assembly. Surrounded by a sealing air film, each screw expertly compresses the gas through a tri-phase sequence: suction, pressurization, and exhaust, delivering unparalleled efficiency.
First Stage Compression: Our process begins with the low-pressure rate screw assembly deftly drawing in gas through a meticulously crafted suction valve. The gas undergoes gradual compression within the chamber and is skillfully transferred to the second stage, orchestrated by the powerful rotation of the screw rotor. This stage ensures that the gas is optimally prepared for high-pressure compression, setting the foundation for superior performance.
Second Stage Compression: At this critical juncture, the gas is expertly guided into a narrower screw space, where it is subjected to compression at higher temperatures and pressures. As the process reaches its peak, the high-pressure gases are smoothly expelled from the system upon the exhaust valve's opening, completing the compression cycle with finesse and precision, highlighting our cutting-edge technology.
The sophisticated process starts with ambient air being meticulously filtered before entering the initial compression stage. Here, it is precisely blended with a minimal quantity of lubricating oil. This mixture is compressed to interstage pressure and expertly directed through a cooling channel, encountering a significant amount of oil mist that notably reduces its temperature. The cooled gas then advances to the second stage for further compression, ultimately being released through the exhaust valve. This comprehensive and thorough sequence culminates in a successful compression process, ensuring outstanding results.
Experience the pinnacle of cooling technology with our water-cooled compressors, expertly leveraging the extraordinary thermal management of water. This system enhances lubrication, drastically prolonging the life of components that are traditionally susceptible to wear. As the cooling water circulates, it performs dual functions: purifying the interiors with precision and dissipating heat from both the cylinder and compressed gas with remarkable efficiency. This advanced cooling system yields lower exhaust temperatures and reduced power consumption, culminating in impressive operational cost reductions. To maintain peak performance and extend the system's lifespan, regularly inspecting and preventing scaling is imperative.
