The role of screw type compressor in Tunnel Engineering

 

Tunnel production is a complex and challenging process that requires various tools and machinery for drilling, blasting, ventilation, and material handling. Many of these works depend on pneumatic tools that need constant compressed air. In tunnel production, one of the vital pieces of equipment is a screw type compressor that delivers constant compressed air in drilling, blasting, ventilation, and many more. Let’s take a look in depth at how a rotary screw type air compressor plays an essential role.

What is a screw type compressor?

A screw type compressor, known as a rotary screw air compressor, is a type of positive displacement compressor using two male and female rotors for rotating helical screws. These two screws rotate and trap the compressed air between them and deliver constant airflow. A rotary screw type air compressor is engineered for heavy-duty applications with continuous compressed air in harsh environments. These compressors are available in oil-injected and oil-free models, depending on the need.

Why screw type compressor is ideal for tunnel production:

• Constant supply of compressed air:

Tunnel engineering is a complex procedure, and underground mining is where a safe work environment is paramount. A rotary screw type air compressor can deliver a constant supply of compressed air without any interruption can, making it a jackpot tool in the mining industry.

• Energy-efficient:

A screw type compressor consumes less fuel in the harsh environment compared to another compressor, making it energy-efficient for tunnel construction.

• Low maintenance:

A rotary screw type air compressor has fewer moving parts, means lower wear and tear, leads to low maintenance and reduces the risk of unexpected breakdowns.

• Able to operate in harsh environments:

A screw type compressor is able to tolerate dust, moisture, and heat, making it a reliable choice in tunnel construction.

• Portable and compact models:

Screw air compressor manufacturers facilitate the portable models according to production needs which is useful in confined tunnel spaces.

The role of screw air compressor in tunnel production:

• Drilling and blasting:

 A screw type compressor is used to power pneumatic tools such as jackhammers and drills, which is vital for excavating rock and concrete. Compressed air is also used to blow out debris from the holes when they are drilled.

• Ventilation:

A rotary screw type air compressor is used to power the ventilation system, which is vital to remove dust, harmful gases and provide fresh air to the workers. This is most important, especially the underground where fresh natural ventilation is little.

• Shotcrete applications:

Compressed air is used to stabilize tunnel walls after excavation. It is used to power the spray equipment and provide the necessary pressure to spray shotcrete.

• Dewatering system:

In tunnel production, usually faces water intrusion from underground. A screw type compressor is used to power pneumatic tools to remove water and keep the construction clean, safe and dry.

• Powering pneumatic tools:

A screw type compressor is used to power pneumatic equipment such as pumps, grinders, and saws that are used in tunneling excavation.

• Maintaining:

 A screw type compressor is used to power the maintenance equipment, such as sandblasters and paint sprayers, for cleaning and painting tunnel walls and ceiling.

Conclusion:

A screw type compressor is a vital tool in tunnel construction due to its ability to work under pressure in harsh conditions without any interruption, making it the ideal choice. A rotary screw type air compressor is energy-efficient, reliable and has a constant supply of compressed air, enhancing the efficiency and productivity of the project. Choosing the right screw compressor can assure optimal performance and safety while minimizing operating costs and downtime.
