Why temperature is important
The hydraulic fluid is the lifeline of the hydraulic system, providing lubrication, power transmission and heat dissipation. When the fluid is overheated, its viscosity is reduced, resulting in:
Reduced efficiency: reduced ability of the system to perform tasks.
Increased wear: Accelerated wear of components causing premature failure.
System failure: severe overheating will lead to catastrophic system failure.
Causes of overheating
Hydraulic fluid overheating can be caused by several factors:
Heavy load: long-time operation under heavy load will cause overheating.
High temperature environment: high temperature environment will accelerate overheating, especially outdoor equipment.
Poor fluid quality: Use of the wrong type of fluid or contaminated fluid may result in heat build-up.
Cooling solutions
To maintain optimum performance, an effective cooling strategy must be used:
Hydraulic cooler of plate heat exchanger
Plate heat exchanger hydraulic coolers are an efficient solution for precise temperature control. It works by transferring the heat from the hydraulic fluid to the cooling medium, usually water or oil. The fluid flows through a narrow passage in the heat exchanger where it exchanges heat with the cooling medium.
Main advantages:
High efficiency: high efficiency heat transfer with large surface area.
Compact design: ideal for space constrained applications.
Universal: applicable to various hydraulic systems.
Fan Drive Hydraulic Oil Cooler System
The fan driven hydraulic oil cooler system uses forced air to dissipate heat from the hydraulic fluid. The fluid flows through a series of tubes or plates and the fan blows air over the surface to cool the fluid.
Main advantages:
Efficient cooling: efficient heat dissipation at high temperature.
Cost performance: relatively simple and affordable.
Mixed method
In some cases, a combination of plate heat exchangers and fan driven coolers can provide optimal cooling performance. Fan driven coolers can handle peak loads while plate heat exchangers provide consistent cooling.
By understanding the cause of hydraulic fluid overheating and implementing effective cooling solutions, such as plate heat exchanger hydraulic coolers and fan driven hydraulic oil cooler systems, you can dramatically improve the performance, reliability, and service life of your hydraulic systems.
