ROCK DRILLING RIG, METHOD FOR CONTROLLING THE TEMPERATURE OF ITS DRIVE EQUIPMENT, AND LIQUID COOLING SYSTEM

摘要

The invention relates to a rock drilling rig, a method for controlling the temperature of its drive equipment, and a liquid cooling system. The rock drilling rig (1) comprises combustion-engine-free drive equipment (16), which includes electric components (K) for affecting transfer drive (43). The rock drilling rig is also provided with a liquid cooling system (21), to which one or more electric components affecting the transfer drive are connected to be cooled by the system. The cooling of the components is controlled by a control unit (C) according to a strategy set therein. The cooling system may additionally be precooled before the transfer drive.
