Large Size Diesel Screw Air Compressor

large size diesel screw air compressor Solution

 

 

The diesel mobile screw air compressor is suitable for different operation intensities and environmental requirements,such us:

In the mining industry: It is suitable for scenarios such as open-pit mines and underground mines, continuously providing stable compressed air for equipment such as rock drills, hydraulic hammers, and pneumatic drills. It can withstand harsh environments with high altitudes, heavy dust, and significant temperature differences. Whether it is shallow-hole blasting or deep mining, it can ensure the efficient operation of the equipment, solve the problem of no power supply from the grid in remote mining areas, and improve mining efficiency and operational safety.

In the field of engineering construction: It covers scenarios such as road and bridge construction, tunnel excavation, building demolition, and municipal engineering. It supplies air to construction equipment such as pneumatic wrenches, spray pumps, and impact drills. It can be flexibly moved to the construction site and is suitable for the characteristics of remote areas without power supply and scattered operation sites. It is particularly applicable to large-scale infrastructure projects such as the Sichuan-Tibet Railway and the Dianzhong Water Diversion Project, helping to shorten the construction period.

In the oil and exploration field: It is used for field exploration of oil and gas, well drilling, and deep hole drilling operations. It can provide compressed air with high pressure and stable flow, meeting the operational needs of remote exploration sites in the wild. It can withstand complex conditions such as high temperature, high humidity, and strong vibration, ensuring the continuous and stable operation of exploration equipment, and facilitating the efficient exploration of oil and gas resources and underground water resources.

 

 

The following models of screw rotary type air compressor machines are suitable for medium-sized to large pneumatic tools and the simultaneous use of multiple devices, and are highly popular in the market:

Model	Air Displacement (m³/min)	Working Pressure (bar)	Suitable groups and advantages
550-13	15.6	13	Ideal for small and medium-sized mines and tunnel construction teams. It precisely matches a single rock drill machine and offers high cost-effectiveness.
18/18	18	18	Designed specifically for well drilling and geothermal projects, with a 18 bar high pressure suitable for deep hole core drilling operations. The performance is balanced and stable.
20/20	20	20	Serving enterprises engaged in large-scale pile foundation projects and deep drilling in hard rock. With ultra-high pressure and sufficient air volume, the drilling efficiency for hard rock layers is much higher than that of conventional machines, thus shortening the construction period.
31/25	31	25	Suitable for large-scale open-pit mines and engineering leasing companies. It provides high-pressure centralized gas supply with large flow capacity, capable of simultaneously driving multiple drilling machine equipment. No need for multiple machines to be connected in parallel.

 

Core technical challenges: In remote areas without power grids or with unstable power supplies (such as in mines and tunnels), the startup and operation of the equipment are restricted; at the same time, harsh environments such as high altitudes (like the Sichuan-Tibet Railway) and large temperature differences (-10°C to 50°C) can easily lead to a decrease in equipment efficiency or equipment shutdown.

The consequences of not resolving:

Time cost: Due to power issues, the project was halted, resulting in a potential loss of tens of thousands to hundreds of thousands of yuan in project schedule costs each day.

Equipment failure rate: For general equipment operating in dusty and high-humidity environments, the failure rate may increase by 30% to 50%, significantly increasing maintenance expenses.

 

Solution and Configuration Suggestions

Core Strategy: Utilize mobile diesel-driven screw air compressors, which are self-powered and can be flexibly moved.

Operational Details:

On-site Installation: Ensure it is placed on a flat and ventilated area, away from flammable materials. Before the first use, make sure to check the oil, fuel, and air filter.

Maintenance Points: Utilize the side door and centralized fueling port design to standardize daily inspections (such as oil level and filters) within 5 minutes.

Multi-unit Parallel Operation: For large drilling rigs or multiple pneumatic tools, parallel operation of the same model units can be adopted for centralized gas supply. It is necessary to ensure that the pressure settings of each unit are consistent.

 

Application Scenario (Pressure & Flow)	Recommended Model	Air Displacement (m³/min)	Working Pressure (bar)
Single medium & large hydraulic breaker or rock drill	550-13	15.6	13
Deep hole drilling & water well drilling (high pressure requirement)	18/18	18	18
Ultra-high pressure high-efficiency drilling operation	20/20	20	20
Air supply for large drilling rig or multiple pneumatic equipment simultaneously	31/25	31	25

 

After implementing this solution, all the problems have been directly improved. The diesel-driven system has completely rid itself of reliance on the power grid and can be deployed at any off-grid site at any time; the equipment is specially designed for extreme environments and can operate stably within the temperature range of -10°C to 50°C and in high dust conditions; daily maintenance only takes 5 minutes, significantly reducing downtime; at the same time, the optimized matching of the main unit and the engine can save 5% to 10% of fuel costs. Every initial problem has been solved in a closed loop in terms of power supply, adaptability, maintenance and energy consumption.

 

 

High efficiency and energy saving: Equipped with a renowned brand diesel engine and independently developed screw compressor, it saves 5% to 10% fuel compared to similar products.

Easy mobility: Equipped with heavy-duty axles, lifting rings and towing rods, it can be easily deployed to any location on the construction site.

Adaptation to extreme environments: -10°C to 50°C stable startup and operation, applicable in highlands, deserts and rainforests.

Intelligent control: The LCD panel displays real-time parameters and features fault self-diagnosis and automatic protection functions.

Maintenance convenience: Side-opening box door and centralized oil filling port. Routine inspections can be completed in just five minutes.
