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).
[pdf] Heat transfer between the working fluid and machine parts within a screw compressor does not affect its performance significantly because the thermal energy dissipation is usually less than 1% of the.
