What are the core technologies of oil-free screw air compressors?
Core Technologies of Oil-Free Screw Air Compressor
I. Core Main Unit Technology
Dry-type oil-free screw rotor: Special oil-free profile, zero lubrication in the compression chamber, pure dry compression, eliminating oil contamination at the source.
Special coating / material: The rotor is coated with PTFE/PEEK or corrosion-resistant alloy, wear-resistant, high-temperature resistant, non-sticky, ensuring stable gap for a long period.
Precise gap control: Micrometer-level assembly tolerance, maintaining efficient internal leakage control under high-temperature conditions, no loss of efficiency.
Multi-stage seal and bearing protection: Multiple labyrinth seals + air seals + oil seals isolation, completely isolating the bearing from the compression chamber, no oil leakage.
II. Power and Drive Technology
High-efficiency permanent magnet synchronous motor: IP54/IP55 protection, high efficiency, low temperature rise, low loss, suitable for long-term continuous operation.
Permanent magnet variable frequency speed control: Supplying gas as needed, maintaining constant pressure, eliminating idle energy consumption, outstanding overall energy-saving effect.
Direct connection / gear transmission: No belt loss, higher transmission efficiency, less vibration, long service life, no maintenance required.
III. Control and Monitoring
Intelligent PLC control system: Automatic start-stop, load regulation, multi-machine interlocking, remote monitoring, self-diagnosis of faults.
Precise pressure / temperature protection: Real-time monitoring of exhaust temperature, oil pressure, vibration, automatic protection in case of over-temperature or over-pressure.
IV. Cooling and Noise Reduction
Efficient independent cooling system: Graded cooling of the rotor, motor, and lubricating oil (bearing lubrication), stable operation in high-temperature environments.
Fully enclosed soundproof cover + low-noise fan: Optimized air duct and sound-absorbing materials, lower operating noise.
V. Post-treatment and Compliance
Integrated drying filtration: Cold dry / micro-heat / no heat regeneration drying, ensuring dew point and cleanliness meet standards.
CLASS 0 oil-free certification: Compliant with ISO 8573-1 CLASS 0 oil-free standard, meeting high cleanliness requirements for food, medicine, electronics, etc.
It is necessary to organize these core technologies into a one-page PPT summary or translate them.
