Whether in a truck, excavator or other utility vehicle, hydraulic oil plays an important role. It affects the efficiency, durability and safety of hydraulic systems, so it is worth choosing it carefully. This text will present the functions of the oil, its most important parameters and practical tips on how to choose the right product to ensure the longest and trouble-free operation of the equipment.
The main function of hydraulic oil is to transfer energy in hydraulic systems. It is also responsible for:
lubrication – reduces friction between moving parts, which reduces component wear;
cooling – removes heat generated during operation of the hydraulic system;
corrosion protection – prevents rust from forming on metal parts;
Removing contaminants – the oil collects and transports fine contaminant particles to the filter.
The best hydraulic oil also helps maintain the right pressure in the system and affects its efficient operation. Regular monitoring and maintenance of its level ensures a longer life of the system and minimizes the risk of failure.
How to choose hydraulic oil? First of all, you should pay attention to the following parameters:
viscosity – one of the most important characteristics. Viscosity affects the fluidity of the oil and its ability to carry loads. Hydraulic oils are classified according to ISO 6743/4 and have viscosity classes such as HH, HL, HR, HM and HG;
recommended weather conditions – in our climate zone, viscosity class 46 is recommended, while in a moderate, cool or circumpolar climate, class 32. HL class oils are suitable for operation in stable temperature conditions, while HLP and HV classes perform better in variable temperatures;
intensity of machine use – hydraulic oils must meet the requirements of different types of machines and their intensity of use. For machines operating in difficult conditions, higher quality oils are recommended;
quality classes – according to DIN 51 524 part II and III, hydraulic oils are classified as HL, HLP, HVLP. Class HL is often used in closed rooms with a stable working temperature. HLP or HV oils are suitable for outdoor use, where the temperature may change in summer and winter.
The machine manufacturer's specifications must also be considered to ensure full compatibility with the hydraulic system. The right hydraulic oil for your truck and other equipment is essential to making your equipment more efficient.
Here is a simple algorithm that will tell you how to choose hydraulic oil. First, you need to identify the requirements of the hydraulic system – it is best to check the manufacturer's technical specifications to find out what the recommendations are for the type and class of oil. Then it is time to assess the operating conditions – you need to take into account the ambient temperature, humidity and intensity of use.
With this information, you can choose the right hydraulic oil viscosity and quality class (as mentioned above, for machines working indoors, the HL class will be appropriate, for those working outdoors, in variable temperatures, the HLP or HV class oils will be a better choice). If you still have doubts about which hydraulic oil to use, consult the supplier of these products or a mechanic.
Regularly changing the hydraulic oil is essential to keeping the hydraulic system in good condition. Recommendations for oil change intervals may vary depending on the machine manufacturer, oil type, and operating conditions. Generally, the hydraulic oil should be changed every 1,000 to 2,000 hours of machine operation. More frequent changes may be necessary under heavy use or in difficult conditions.
Before changing the hydraulic oil, you should also check the condition of the oil filter and replace it if necessary, and thoroughly clean the hydraulic system from contamination. When changing, follow the machine manufacturer's recommendations in the manual and the information on the oil label.
Choosing the right hydraulic oil is crucial for the performance and durability of hydraulic systems in trucks, machines and delivery vehicles. Remember to consider parameters such as viscosity, operating conditions and the intensity of machine use. Regularly changing hydraulic oil helps keep machines in optimal condition
