Excessive oil temperature will have a series of adverse effects on the system, such as reduced viscosity, increased leakage, and reduced volumetric efficiency, resulting in hydraulic speed not Stability, will cause gaps between motion amplitudes with different thermal expansion coefficients, and even jams will cause deterioration of the oil, aging of seals, and deterioration in sealing performance. There are many reasons for the increase in oil temperature. For example, the volume of the fuel tank is too small, the heat dissipation area is insufficient, the amount of oil stored in the fuel tank is too small, the ambient temperature is high, and the cooler fails. There is no offload circuit in the system. Overflow under high pressure; oil pipe is too thin and long, excessive bending, excessive pressure loss, parts processing accuracy is not high, and frictional heating of... less
