The waste hot recovery equipment introduces high-temperature circulating oil and high-temperature compressed air into the heat water unit. The heat generated during the operation of the air compressor is fully absorbed by the water heater. And the compressor can be cooled down at the same time.
[pdf] Heat treatment for rock drilling tools typically involves processes such as annealing, normalizing, quenching, and tempering. These techniques greatly enhance the tool’s hardness, wear resistance, strength, and toughness, ensuring optimal performance even in demanding working conditions.
[pdf] External air is introduced into the air compressor through forced convection by a cooling fan. When the air flows through the plate-fin radiator, it carries away the heat generated by the compressor (including lubricating oil and compressed air).
