What are the functions of hydraulic oil coolers

Hydraulic oil coolers are used in construction machinery with hydraulic oil as the transmission medium, such as excavators, concrete delivery pumps, fine sand slurry pumps, boom pumps, on-board pumps, pile drivers, trenchers, rotary drilling rigs, pavers, trenchless equipment, air compressors, road rollers, etc. This series of products are mainly used in the circuit of hydraulic system. During operation, the high-temperature oil in the hydraulic system flows through the hydraulic oil cooling device, and carries out efficient heat exchange with the forced cold air in the heat exchanger to reduce the oil temperature to the working temperature, so as to ensure the continuous normal operation of the main engine and good work.
