High-speed rail special screw air compressor pump head
Screw Air Compressor Pump for High-Speed Train (EMU/HST) Braking, Suspension and Auxiliary Pneumatic Systems Overview This screw air compressor pump is purpose-built for high-speed train (EMU/HST) braking, suspension and auxiliary pneumatic systems, integrating a high-efficiency screw main unit into a compact, lightweight package. It delivers stable, clean, oil-free (or oil-injected, per system design) compressed air to keep braking, door, pantograph and suspension components operating reliably during continuous high-speed operation. Engineered for low noise, low vibration and long service intervals, it meets the strict reliability and safety demands of railway applications. Core Features • High-Efficiency Screw Airend: optimized rotor profile ensures high volumetric efficiency, stable output pressure and low energy consumption. • Rail-Specific Compact Design: integrated structure saves space and weight — critical for underframe and equipment-room installation. • Clean Air Delivery: oil-free or oil-separated options available to protect sensitive pneumatic components and brake systems. • Low Noise & Vibration: precision balancing and acoustic insulation make it suitable for passenger comfort and urban/night service. • Durable & Low Maintenance: wear-resistant construction, extended oil service life and easy filter/oil change reduce lifecycle cost. • Wide Operating Range: performs reliably across extreme temperatures, altitude and high-humidity environments. Technical Specifications (Typical) Item Specification Application High-speed train braking, air suspension, door control, pantograph & auxiliary pneumatics Flow Capacity 0.3 ~ 3.0 m³/min (customizable) Working Pressure 0.8 ~ 1.3 MPa (adjustable) Compression Type Oil-injected / Dry oil-free screw (optional) Power Rating 5.5 ~ 37 kW (AC 380/440 V, 50/60 Hz or DC power) Speed Range 1500 ~ 3000 rpm Cooling Method Air cooling / Water cooling Noise Level ≤ 72 dB(A) (at 1 m) Protection Grade IP54 / IP55 Lubrication Special railway-grade oil, long-life design Mounting Type Direct flange mounting / Flexible coupling Dimensions & Weight Customized per train model and space envelope Benefits • Ensures consistent air supply for critical braking and suspension safety functions. • Reduces downtime with extended maintenance intervals and high reliability. • Lightweight and space-saving design maximizes train payload and interior layout flexibility. • Low noise and vibration improve passenger comfort and meet railway noise regulations. • Long service life and proven durability reduce total cost of ownership.
