  • What are the causes and effects of excessive oil temperature in the hydraulic system?

    Hydraulic systems tend to generate heat during operation, especially when under high load or long-term operation, the hydraulic oil temperature tends to rise. Excessive oil temperature not only affects the performance of the system, but also accelerates the wear of components and even causes early failure of equipment. Therefore, a deep understanding of the factors affecting hydraulic oil temperature, the negative impact of excessive oil temperature on the system, and effective temperature management strategies are essential to ensure efficient and stable operation of the hydraulic system.
