Extend the Service Life of Your Hydraulic System through an Oil Cooler

Blog | April 7th, 2022

Many machines today rely heavily on hydraulics in carrying out their core functions. Hydraulics have been helpful to a lot of industries as they are powerful, versatile, reliable, and safe. 

Hydraulic systems work by maximising hydraulic fluid in transferring energy from an electric motor to an actuator. The hydraulic fluid often comes from the reservoir. Once a machine or tool starts to operate, the hydraulic pump is tasked to move the hydraulic fluid from the reservoir throughout the system. It can also convert mechanical energy into hydraulic power. In regulating the liquid flow, hydraulic systems maximise valves, which can also help in alleviating extra pressure whenever necessary. The hydraulic cylinder, ultimately, reverts hydraulic energy into mechanical energy.

All components inside the hydraulic systems generate heat, especially when they are working. Without regulating the temperatures, they can gradually affect the operations of the hydraulics until they stop working optimally. Hydraulic machines may end up manifesting leakages and getting damaged.

Oil Cooler is the Main Solution

The absence of any measures and tools will only cause hydraulic systems to fail. As they generate more heat, the viscosity of the hydraulic fluid will become affected. It can also lead to system wear, damaged lubricative film, increased cavitation risk, and reduced system lifespan. Fortunately, all these issues can be prevented once they are integrated with an oil cooler.

An oil cooler is a component that can regulate the temperature of the hydraulic fluid. It permits the fluid to pass through a coil or core, which can reduce its generated heat. An oil cooler can also prevent the surroundings from affecting the quality of the hydraulic fluid.

Oil Cooler’s Working Principles

Industries can choose from different types of oil coolers. But one of the most common types of oil coolers follows the principle of conductive transfer. This type of oil cooler processes the hydraulic fluid by passing it to a series of thin pipes that are exposed to a cooling medium. The heat from the hydraulic fluid then flows into the cooling medium. Both the hydraulic fluid and the cooling medium constantly move inside the cooler, preventing them from achieving thermal saturation and equilibrium.

Most oil coolers utilise either air or water as their base coolant medium. Air-based oil coolers utilise powerful fans in introducing air across the pipe coils. Water-based oil coolers, alternatively, allow cold water to circulate inside the sealed shells or tubes.

Benefits of Utilising Oil Coolers

Once an oil cooler has been installed, the hydraulic fluid is expected to become thicker, which can then regulate the functions of the entire hydraulic machine. It can likewise prevent the hydraulics from overheating. An oil cooler can also help maintain the optimal temperatures of the fluid, extend the service life of the hydraulic machine and its components, and minimise the need for maintenance and repairs.
