Screw air compressors are high-efficiency, high-performance air compressors that come pre-assembled, requiring only a single power connection and compressed air connection, and feature an integrated cooling system, greatly simplifying installation. The core component of a screw air compressor is the screw compression unit, which is internally manufactured on precision CNC grinding machines and paired with online laser technology to ensure unparalleled manufacturing tolerances. This design ensures the compressor's reliability and performance, making it highly cost-effective in operation while ensuring all components achieve optimal cooling and longevity. The main advantages of screw air compressors include high stability, efficiency, low vibration, and low noise, making them an ideal choice for providing compressed air across various industries.
The operating principle of screw air compressors is based on the operation of the screw compression components, which consist of two rotors driven by an electric motor, achieving the intake, compression, and exhaust of air. During the intake process, the motor drives the rotors, filling the air between the teeth. As the rotors rotate, the enclosed volume between the rotor teeth and the housing decreases, compressing the gas. In the compression phase, the lubricating oil, turned into a mist due to the pressure difference, is sprayed into the compression chamber to achieve compression, temperature reduction, sealing, and lubrication. When the enclosed teeth of the rotor rotate to meet the exhaust port of the housing, the compressed air begins to discharge, completing the exhaust process. This series of operations ensures that screw air compressors can provide compressed air efficiently and stably.
The screw air compressors are categorized into single-screw and double-screw types. The single-screw air compressor consists of a cylindrical screw and a pair of mating flat star wheels symmetrically arranged, while the double-screw compressor is made up of two rotors. Both types are widely used due to their rational structure, good force balance, and long lifespan.
