1. Product introduction
Screw air compressor, abbreviated as screw compressor, is a type of rotary positive displacement compressor. Its core components are a pair of meshing male and female rotors. As the rotors rotate within the casing, the volume between their teeth continuously changes, thereby completing the suction, compression, and discharge of gas. This machine model features stable operation, low vibration, lower noise, simple maintenance, and high energy efficiency. It is widely used in industrial fields such as manufacturing, chemical industry, mining, pharmaceuticals, and food, and is one of the mainstream compressor models in the current market.
Since the birth of this technology in the 1930s, product performance has been greatly improved through technological innovations such as oil injection technology, rotor profile optimization, permanent magnet frequency conversion, and two-stage compression. China began research and development in the 1960s and has achieved large-scale production through technology introduction and independent innovation. Domestic models account for more than 70% of the domestic market share.
2. Product Classification
‌Classified by lubrication method‌
Oil-injected screw air compressor: Lubricating oil is injected into the compression chamber for cooling and lubrication. It has a mature structure and moderate cost, making it the mainstream general-purpose model in industrial scenarios.
Oil-free Screw Air Compressor: The compression chamber does not contact lubricating oil, outputting completely oil-free clean compressed air, suitable for industries with extremely high requirements for air source cleanliness, such as medicine, food, and semiconductors.
‌Classified by speed control method of the drive‌
Industrial Frequency Screw Air Compressor: Driven by a fixed-speed motor, it has a simple structure and low failure rate, suitable for continuous operation scenarios with stable air consumption load.
Variable Frequency Screw Air Compressor: Regulates motor speed through frequency conversion technology, matches exhaust volume on demand, achieves significant energy saving, suitable for scenarios with large fluctuations in air consumption load.
Permanent Magnet Variable Frequency Screw Air Compressor: Adopts a permanent magnet synchronous motor, further improving energy efficiency ratio, achieving 20%-40% energy saving compared to fixed frequency models, and is the current mainstream energy-saving upgrade model.
‌Classified by mobility characteristics‌
Stationary Screw Air Compressor: The entire unit is fixedly installed, with stable air delivery volume, suitable for scenarios such as factory workshops and other fixed air source points.
Mobile Screw Air Compressor: Integrated with a mobile chassis, supports electric, diesel, or battery drive, protection rating ≥ IP54, adaptable to high-temperature and dusty outdoor operating environments, suitable for outdoor mobile operation scenarios such as mining, municipal engineering, and tunnel excavation.
3. Product features
‌Extremely strong operating stability‌: Specially designed for all-weather continuous operation, can run 24 hours a day without interruption, with small vibrations and few wearing parts, significantly reducing the failure rate compared to traditional piston air compressors.
‌Excellent Energy Efficiency Performance‌: Modern models use an optimized asymmetric rotor profile, significantly reducing internal leakage and enclosed volume, greatly improving volumetric efficiency, with energy-saving advantages being particularly prominent in permanent magnet variable frequency models.
Wide range of operating condition adaptability: By configuring different after-treatment equipment, compressed air with different pressures and different cleanliness levels can be flexibly output, adapting to various air consumption needs from ordinary pneumatic tools to high-precision pharmaceutical production.
‌Simple Maintenance‌: The core vulnerable parts are only conventional consumables such as lubricating oil and filter elements, requiring no complex professional calibration. The daily operation and maintenance threshold is much lower than that of piston compressors.
4. Product advantages
Strong production continuity assurance capability: Stable air pressure output without fluctuations, high reliability for continuous operation, will not affect production rhythm due to frequent start-stops, significantly reducing the risk of production shutdowns caused by air source interruptions.
‌Long-term energy consumption costs are controllable‌: Energy-saving models such as permanent magnet frequency conversion can dynamically adjust output according to actual gas consumption needs. Compared with traditional models, long-term operation can save a large amount of electricity costs, and the additional investment in equipment upgrade can be recovered through energy-saving benefits within 2-3 years.
‌Outstanding adaptability to extreme environments‌: The mobile model can operate stably in high-temperature environments up to 52℃, with a protection rating of ≥IP54. It can be directly used in harsh conditions with dust and humidity in the field, suitable for extreme scenarios such as mines and oil and gas extraction.
High comprehensive cost-effectiveness throughout the entire life cycle: The equipment lifespan generally reaches 8-10 years, daily maintenance costs are low, and the supporting after-treatment system can be expanded with functions as needed, eliminating the need for frequent replacement of the entire unit. The long-term comprehensive operating cost is far lower than that of traditional reciprocating air compressors.
