deep well screw air compressor with dual condition design

Deep well screw air compressor is a high-performance equipment designed for deep well operation, widely used in mining, oil drilling and geothermal development.

Description

With outstanding performance and adaptability, the deep well screw air compressor provides stable air support to ensure an efficient and reliable operating environment. Engineered for demanding applications, it is a top choice for ensuring project success in harsh and variable environments.

Introduction of Deep Well Screw Air Compressor

Designed for a maximum pressure of up to 40 bar, this compressor series uses advanced two-stage screw compression technology to boost compression efficiency and reduce energy consumption. The power system features heavy-duty diesel engines from leading brands such as Yuchai and Cummins, delivering strong power and excellent fuel economy. Heavy-duty construction and high-performance SKF bearings ensure reliable long-term operation even under high-load conditions.

Main Features

  1. High-efficiency two-stage compression design: Increases compression efficiency and reduces energy use. The flexible poppet valve design adapts to different working conditions for stable operation.
  2. Flexible double working condition switching: Users can easily switch between two working modes, such as 33 m³/min at 25 bar or 26 m³/min at 35 bar, meeting varying operational needs.
  3. Low-temperature starting system: Fuel heater and circulation system ensure smooth engine starts even in extreme cold or high-altitude conditions, enhancing adaptability.
  4. After-cooler and air-water separator: Keeps outlet air temperature within 15°C of ambient, suitable for downstream equipment with strict intake air requirements.
  5. Remote control and monitoring: Features remote start-stop, monitoring, and positioning for real-time management and maintenance, improving operational efficiency.

Working Principle of Deep Well Screw Air Compressor

Using the screw compression principle, the rotating rotors draw in and compress air in the inter-rotor space. Two-stage compression first brings air to intermediate pressure, then further compresses it to the desired high pressure, improving efficiency and lowering energy consumption.

Application Areas

  • Mining: Provides stable air for mining equipment, supporting pneumatic tools and ventilation systems.
  • Oil drilling: Supplies high-pressure gas during drilling to assist mud circulation and downhole operations.
  • Geothermal development: Used in geothermal resource exploration for gas lift, testing, and various processes.
  • Deep well construction: Delivers compressed air support for deep well operations including water wells and geological exploration.
