How to ensure energy efficiency in hydraulic systems?

Hello! In this week’s article, we will discuss some important steps to increase energy efficiency in hydraulic systems. Hydraulic systems generally convert mechanical energy into hydraulic energy using hydraulic oil, allowing us to generate power. These systems play a critical role in mobile, agricultural, and industrial applications. Optimizing energy efficiency through proper design and maintenance have great importance. Now, let’s take a closer look at this topic together!

Hydraulic systems are power transmission systems widely used in industrial applications. However, the energy efficiency of these systems can decrease if proper design and maintenance are not performed. At Hidros Group, we provide the most suitable solutions by evaluating with our partners during the design phase of our custom hydraulic blocks and hydraulic mini power units.

• Proper Hydraulic Pump Selection

One of the fundamental aspects of energy efficiency in hydraulic systems is the proper selection of the pump. Hydraulic pumps function as the heart of the system, providing flow under load. Proper sizing and selection of the pump according to the working pressure optimize energy consumption. High-efficiency gear or piston pumps save energy and enhance system performance. Hydraulic pumps typically operate in the range of 1200 to 3600 rpm, with maximum pressure values ranging from below 70 bar to over 410 bar. Besides pressure, the flow rate of the pump is another critical point when substituting different pump types.

• Flow Control and Pressure Adjustment

Flow control and pressure adjustment significantly affect energy consumption in hydraulic systems. Adjustable valves tailored to the need prevent unnecessary energy losses. A system with correctly set pressure not only saves energy but also extends the life of the components.

• Sealing and Maintenance

Sealing is a major source of energy loss in hydraulic systems. Regularly checking for leaks and ensuring the quality of sealing elements is necessary. Additionally, regular maintenance and the replacement of filter elements/oil help maintain system performance and energy efficiency. Suitable sealing elements should be chosen, considering the operating temperature of the system.

• Efficient Valve Selection

Hydraulic valves control the energy distribution within the system. Choosing the right valve is essential for energy efficiency. Advanced technology valve systems optimize energy consumption and improve system response. It is necessary to select a valve of appropriate size by evaluating the system’s operating pressure and flow rate. These valves should be chosen to match the flow within the system.

• Compatibility of Hydraulic Equipment with Environmental Conditions

It is important that the equipment used in hydraulic systems is suitable for environmental factors. Especially in outdoor or extreme temperature variation areas, the durability and performance of the equipment should be determined according to environmental conditions. Stainless steel materials or special coatings can prevent equipment from corrosion, ensuring the materials are long-lasting and increasing energy efficiency.
