Hydraulic systems, such as those found in heavy construction equipment and trucks, require proper cooling. A hydraulic oil cooler is an important part of this process. Its proper selection can significantly affect the efficiency and durability of the entire system, preventing overheating and failures. Below are the criteria for selecting a cooler for a specific application.
Cooling hydraulic oil is essential to ensure optimum operating conditions for the system. Every hydraulic system generates heat during operation. This is a natural effect of mechanical and hydraulic components. The more complex the system, the more components it has and the longer it is used, the greater the risk of excessive temperature increase. High temperatures in the hydraulic system can lead to degradation of seals, destruction of hydraulic lines and, in extreme cases, even complete system failure.
Why are hydraulic oil coolers so important? Lack of proper cooling has serious consequences, not only financial, related to expensive repairs, but also health risks for machine operators. Overheated hydraulic oil under pressure can shoot out and cause serious burns. That is why it is so important to use effective methods of cooling hydraulic oil in every hydraulic system.
Good cooling of hydraulic oil also allows for increased energy efficiency of the system. Systems operating in optimal thermal conditions consume less energy, which translates into operating savings. Proper cooling also extends the life of hydraulic oil, which degrades less and loses its lubricating properties.
Hydraulic oil coolers are designed to maintain the oil temperature within the appropriate range recommended by manufacturers. They work by removing excess heat from the oil, which is a key medium in hydraulic systems. The hydraulic oil cooler fan plays an important role in the cooling process. It increases airflow through the cooler, facilitating heat dissipation. Another important element is the hydraulic oil cooler thermostat, which turns on the cooler at a specific temperature, usually between 40 and 48 degrees Celsius.
A properly selected hydraulic oil cooler ensures that the oil does not reach temperatures that could negatively affect the entire system. This can prevent damage and increase the efficiency and durability of the hydraulic system.
The selection of a hydraulic oil cooler depends on several factors, such as the flow in the hydraulic system and the control voltage (available options include 12 V, 24 V and 230 V). It is important that the cooler is adapted to the specific operating conditions of the hydraulic system.
Hydraulic oil coolers can be divided into several groups depending on their flow:
coolers with a flow rate of up to 100 l – are commonly used in trucks, orchard machines and stationary machines;
coolers with a flow rate of up to 150 l – are used in hydraulic cranes (HDS), forestry trailers and slurry tankers;
coolers with a flow of up to 200 l – are used in various forestry machines and hydraulic cranes.
When selecting a hydraulic oil cooler, you should also consider the type of oil used in the system. Hydraulic oils are available in various specifications that affect cooling efficiency. After selecting the right device, it is time for installation, which is not demanding. Simply connect the hydraulic oil cooler to the power supply, connect the connections and tighten the screws. Coolers can usually be mounted in any position.
Hydraulic oil cooling helps ensure the proper functioning of hydraulic systems in heavy construction equipment and trucks. The selection of the appropriate hydraulic oil cooler should be based on the analysis of the flow in the system, the type of oil and the operating conditions. It is also worth paying attention to the quality of the hydraulic oil cooler fan and thermostat, which have a direct impact on the cooling efficiency. This allows you to avoid failures and ensure optimal operating conditions of the hydraulic system.
