The right amount of cold coal is a key factor in ensuring the efficient operation of its cooling system when the Cat excavator is carrying out cold coal filling.First, it needs to be made clear that the cold coal load of Cat excavators of different models and specifications will vary, so before adding cold coal, reference should be made to the official advice provided by the equipment manufacturer or to the detailed usage manual. ].In general, several important factors have to be taken into account in determining the amount of cold coal in the Cat excavator: engine displacement in the excavator, the overall capacity of the cooling system and the impact of ambient temperatures.In order to control the amount of cold coal accurately, measurements and supplements can be made with specialized equipment to avoid excessive or inadequate quantities in order to maintain the cooling system and extend the life of excavators.Compliance with the principle of proportionality is essential when conducting cold coal filling operations.Do not blindly pursue the cooling effect of excess cold coal, which may cause additional pressure on components such as pumps, radiators, etc., and affect the overall performance of excavators.At the same time, it is necessary to prevent too little cold coal from reducing the cooling effect and triggering engine overheating.In summary, there is no uniform standard answer to the question of `how much cold coal is appropriate for the Cat excavator', which requires precision calculation and adjustment according to the specific type, condition and environmental conditions. ].
