AI Technical Summary
Existing air compressors cannot effectively cool diesel engines in extreme low-temperature environments, resulting in poor cooling system fluidity. This makes them unable to meet the needs of global users, especially in special regions with an average annual temperature difference of 40 to 90 degrees Celsius. In particular, water-cooled circulating cooling systems cannot function properly in extreme low temperatures.
It adopts an air-cooled diesel engine structure, including a base, an air-cooled diesel engine, a screw compressor, an oil-gas separator, and a screw oil radiator. Combined with an air filter, controller, and automatic fire extinguisher, it forms a stable cooling system, avoiding the use of antifreeze and intercooled turbocharger radiators, and achieving air-cooled circulation cooling.
Ensuring the normal operation of air compressors in extreme low-temperature environments reduces manufacturing costs, avoids permanent damage, adapts to the special environmental needs of global regions, and provides stable and reliable construction support.
