Electric Compressor
FAQ for Diesel Compressor
An electric air compressor is a general-purpose power device that uses electrical energy as the power source to drive the operation of the compressor main unit and compress atmospheric air into high-pressure gas. It is a commonly used air supply device in the industrial sector, and is different from fuel-driven air compressors such as diesel-powered and gasoline-powered ones.
- The unit price of electrical energy is lower than that of fuel oil, with higher energy utilization rate, resulting in significant cost advantages during long-term continuous operation.
- It generates no pollutant emissions such as exhaust gas and black smoke, operates with lower noise, and is suitable for closed working environments like mines and tunnels.
- The motor features precise speed regulation; when paired with frequency conversion technology, it can adjust air pressure and flow rate on demand, ensuring stable output and a low failure rate.
- It eliminates components such as engines and oil circuits found in fuel-driven air compressors, has fewer wear parts, and allows for simple daily maintenance with longer maintenance cycles.
- Without fuel storage and refueling processes, it eliminates the risks of leakage and flammability, delivering higher safety in flammable and explosive scenarios.
- It can be directly connected to the industrial power grid or paired with a generator to form a mobile power supply system, and its compact structure facilitates layout in narrow spaces.
- First, refer to the technical manuals of drilling equipment and pneumatic tools to confirm their rated working pressure and air consumption, the fundamental basis for parameter matching.
- The rated supply pressure of the air compressor should be slightly higher than that of terminal equipment to offset pressure losses in pipelines and valves, preventing insufficient power or startup/shutdown jitters. Increase the pressure difference appropriately for simultaneous operation of multiple devices or long-distance delivery.
- Calculate the total air consumption of concurrent equipment, factoring in their simultaneous operation rates. The compressor’s rated displacement must exceed total consumption with a margin to meet instantaneous peak demand and ensure continuous operation.
- When paired with an air storage tank, use its buffer effect to moderately reduce the compressor’s displacement margin.
- Thin air in high-altitude mines reduces the compressor’s actual displacement, so increase its rated displacement. In high-temperature mines, choose heat dissipation enhanced equipment and moderately increase pressure redundancy due to reduced heat dissipation efficiency.
- Confirm the compressor's rated power and voltage level first, and compare them with the mine power grid's rated capacity to ensure the grid can bear the compressor's operating load without overload.
- Check if the compressor's voltage level (such as 380V, 660V) is consistent with the mine's power distribution standard to avoid equipment damage or failure caused by voltage mismatch.
- For high-power air compressors, verify whether the mine's power distribution lines, transformers and other supporting facilities can meet the power supply requirements, and ensure compliance with the mine's electrical safety specifications.
Impacts on the air compressor：Unstable voltage or sudden power outages can cause motor current fluctuations, mechanical impacts on components, and damage to the control system. This accelerates equipment aging, shortens the service life of the main unit, and may even directly burn out the motor.
Impacts on drilling operations：Interruption of air supply will force the suspension of drilling operations, which is likely to lead to issues such as bit sticking and burying, and affect drilling accuracy. For underground operations, work suspension may also increase potential safety hazards like gas accumulation.
