Importance of Oil Coolers in Hydraulic Systems Leave a comment

In hydraulic systems, energy conversion or energy transmission occurs in each component except oil tank. This results in mechanical and hydraulic energy loss which is converted into heat. It is extremely important to keep the rising temperature in recommended level.

High temperatures lead deterioration of the fluid in the system, but also damage the seals, orings in the components and hydraulic hoses. According to the seal manufacturers, if the operating temperature exceeds the recommended value by 10 degrees celcius, the seal life is reduced by 80 %. Using a suitable oil cooler in the system extends system life, reduces internal leakage, provides more efficient operation and enables lower maintenance costs. Air-cooled oil coolers are commonly used in mobile applications, and water-cooled oil coolers may be preferred in systems where operation is more intensive.
