Role of oil-injected screw air compressor in drilling

Oil injection screw air compressor mainly plays a role in drillingpower sourceIts role runs through the entire process of drilling operations. The following is explained from three aspects: working principle, core role and advantages:

1. Working principle

1. air compression process
   • The sucked air is compressed to a high pressure state (usually 0.7-1.3MPa) by meshing the screw rotors with each other.
   • During the compression process, the oil injection system atomizes lubricating oil to achieve cooling, lubrication and sealing.
2. energy conversion
   • The motor drives the screw to rotate, converting electrical energy into pressure energy and kinetic energy of compressed air.
   • The compressed air is delivered to the drilling equipment through pipes to drive a pneumatic motor or impact mechanism to do work.

2. Core role in drilling

1. provide sustained momentum
   • Drive pneumatic rock drills, pneumatic down-the-hole hammers and other equipment to achieve efficient rock breaking.
   • In oil drilling, compressed air drives the circulation of drilling mud and assists in the drainage of debris.
2. Enhance operational efficiency
   • Compared with electric drilling equipment, pneumatic equipment responds faster and is suitable for high-frequency impact operations.
   • In mining, compressed air can simultaneously drive multiple drilling equipment to improve the advancing speed of the working face.
3. Ensure operational safety
   • Compressed air has no spark risk and is suitable for drilling operations in flammable and explosive environments (such as coal mine gas areas).
   • Some equipment uses compressed air to discharge slag from the bottom of the hole to reduce the risk of drill sticking.

3. Technical advantages of oil-injected screw air compressor

1. high-efficiency energy-saving
   • The efficiency of screw compression technology is 20%-30% higher than that of piston type, and the energy consumption is reduced.
   • Oil injection cooling reduces compression heat loss and improves energy efficiency ratio.
2. stable operation
   • The enclosed structure reduces leaks and adapts to high temperature and dust drilling environments.
   • Low vibration and low noise, suitable for long-term continuous operation.
3. Convenient maintenance
   • The modular design is easy for maintenance, and the lubricant replacement cycle is as long as 4,000 – 8,000 hours.
   • The intelligent control system monitors operating parameters in real time and warns of faults.

4. Typical application scenarios

summary: The oil-injected screw air compressor provides strong power for drilling equipment through an efficient and stable supply of compressed air, significantly improving operating efficiency and safety. Its technical characteristics are highly matched with the high load and continuity requirements of drilling operations, and it is the core power equipment in the field of industrial drilling.
