diesel powered screw air compressor for deep well drilling

Features of Diesel Powered Screw Air Compressor

1. High-pressure design: Maximum pressure up to 40 bar, ideal for deep well operations requiring high-pressure air.
2. Two-stage compression system: Utilizes two-stage compression with flexible design and poppet valve to enhance efficiency and stability.
3. Rugged and durable: Heavy-duty construction with SKF bearings ensures long-term reliable operation under high loads.
4. Powerful power: Equipped with Yuchai, Cummins, and other heavy-duty diesel engines for excellent reliability and fuel economy.
5. Dual working condition switching: Easily switch between 33 m³/min at 25 bar and 26 m³/min at 35 bar to meet different operational needs.
6. Low-temperature starting system: Built-in fuel heater and circulating coolant enable smooth starting in cold and high-altitude environments.
7. High-efficiency cooling and separation: After-cooler and vapor separator keep outlet air temperature within 15°C above ambient, suitable for equipment with strict intake air temperature requirements.
8. Intelligent control: Features remote start-stop, monitoring, and positioning for real-time equipment status and remote operation.

Working Principle of Diesel Powered Screw Air Compressor

Air is compressed using a pair of intermeshing screw rotors. During intake, air enters through the inlet and is trapped between the rotors and housing. As the rotors turn, the air is compressed as the space decreases and pressure rises, while lubricant is sprayed for cooling and sealing. The high-pressure air is then discharged through the exhaust port—either to a storage tank or directly to end-use equipment. This continuous process guarantees a stable supply of compressed air.

Application Areas

• Deep Well Drilling: Supplies high-pressure air for oil, natural gas, and geothermal drilling, driving tools and removing cuttings.
• Mining: Provides compressed air for drilling, ventilation, and equipment operation in underground mines.
• Water Well Construction: Supports drilling and maintenance of deep water wells to ensure a clean water supply.
• Geological Exploration: Powers drilling equipment for geological surveys and mineral resource assessments.
• Tunnel Construction: Delivers compressed air for drilling, grouting, and machinery during tunnel boring operations.
• Marine Engineering: Supports deep sea drilling and maintenance for offshore platforms and marine projects.
