high pressure and large displacement air compressor

The high-pressure and large-displacement air compressors are designed with a tandem combination of screw compressors and piston compressors, designed to provide a stable supply of compressed gas to locations requiring large air volumes and high-pressure gas supply.

Description

The high pressure and large displacement air compressor is widely used across military, heavy industry, and emergency rescue sectors. Featuring a skid-mounted structure, this unit is highly maneuverable and adaptable, allowing for rapid deployment and efficient operation in diverse environments—making it an ideal solution for applications with rapid inflation and high-pressure needs.

Features of High Pressure and Large Displacement Air Compressor

  1. High displacement and high pressure: Combines screw and piston compressor technologies for powerful gas compression, delivering large displacement and high pressure with stable output even under demanding conditions—ideal for rapid inflation and similar requirements.
  2. Skid-mounted structure: Integrated skid-mounted design makes installation and relocation easy, with low vibration and smooth operation. It enables quick deployment without complex infrastructure, suitable for land and military port terminals.
  3. Automation control system: Built-in advanced PLC programmable controller enables real-time monitoring of pressure, temperature, and other parameters. The system ensures stable operation, with automatic alarms and emergency shutdowns to protect against equipment damage.
  4. Water-cooling and pressure lubrication system: Efficient water cooling ensures stable operating temperatures during prolonged use, while pressure lubrication keeps moving parts running smoothly and extends equipment life.
  5. Motor drive: High-efficiency motor drive ensures optimal energy conversion and transmission, delivering high performance, reduced energy consumption, and minimal environmental impact.
  6. Five-stage compression: Multi-stage (five-stage) compression increases gas pressure step by step, guaranteeing stable and efficient gas supply under varying conditions.

Working Principle

The compressor utilizes a staged compression mechanism: air first enters the screw compressor for initial compression, then passes into the piston compressor for further pressurization. The five-stage compression process ensures efficient pressure build-up, resulting in high-pressure gas output. Real-time PLC monitoring of pressure, temperature, and other parameters maintains optimal performance, while water cooling and pressure lubrication systems ensure smooth, reliable, and long-lasting operation.

Application Areas

  • Military Port Terminal: Rapidly fills warships, submarines, and other military equipment with high-pressure gas, supporting pneumatic and gas-powered units in military operations.
  • Industrial Applications: Serves mining, metallurgy, petrochemical, and other heavy industries, providing high-pressure air for pneumatic control and gas power systems.
  • Land Inflatable Station: Ideal for automotive and tire inflation stations where large air volumes and quick inflation are required, ensuring high efficiency and fast turnaround.
  • Emergency Rescue and Disaster Recovery: Supplies essential high-pressure gas in disaster or rescue scenarios, enabling rapid deployment to critical sites for inflation or gas supply.
  • Other Gas Compression Applications: Suitable for gas storage, compressed gas transmission, and any industrial process requiring continuous, high-flow, high-pressure gas delivery.
