Increase in Hydraulic Automation
The increase of new technologies in hydraulics has elevated both quality of products and the efficiency in how they’re made and operate.
To allow the miniaturization of components, the development of hydraulic hybrids, and the use of advanced materials, automated hydraulics incorporate the digitalization of intelligent controls which provide energy efficiency.
Many external factors are driving these advancements, including the continuing shortages in skilled labor. This continues to increase costs and decrease productivity. Many companies are investing in automated solutions provided by growing technologies in the IIoT. Along with many other industries, this is influencing an increased demand for material handling equipment, one of the fastest growing markets for smart hydraulics. The reduction in skilled labor is driving opportunities for automated pick & place robots, conveyors in distribution and autonomous forklifts.
The automation of hydraulics is becoming increasingly integrated into multiple areas of manufacturing and heavy equipment. Hydraulic systems and various components prove their capabilities by being utilized in industries such as construction, agriculture, healthcare, food processing and the energy sector.
Digital technologies are revolutionizing the industry with IoT connectivity, smart sensors and data analytics advancements, providing enhanced operational efficiency with real-time monitoring and predictive maintenance. These advancements allow organizations to improve productivity while minimizing downtime and reducing costs.
Hydraulic cylinders account for the largest market share of all components. Smart hydraulic cylinders integrate with electronics to increase the operation's accuracy and functionality. This is particularly true in mobile hydraulics, including material handling, construction and agricultural equipment.
1. Intelligent Control Systems
Intelligent control systems are the 4th industrial revolution of hydraulic technology. Artificial Intelligence is driving advanced control strategies and optimization from machine learning algorithms, which enable increased system performance, allowing systems to anticipate requirements and adapt to variable operating conditions. As intelligent controls optimize predictive modeling techniques, they enhance control of hydraulic actuators, reducing wear on components and energy consumption.
2. Increased Sustainability and Energy Efficiency
Improvements in sustainability and energy efficiency have been driven by innovations in hydraulic energy recovery, variable displacement pumps and regenerative braking systems. The optimization of system performance, reductions in energy consumption and minimization of fluid leaks that cause poor performance all enhance sustainable hydraulics that lend themselves to smart power management and hybrid hydraulics, resulting in gains in efficient energy consumption.
3. Hybrid Hydraulics
In recent years, hybrid hydraulic systems have become more prevalent to maximize performance and efficiency. They use electric and hydraulic technologies to operate hydraulic accumulators in storing and releasing energy to enhance electric power sources. Hydraulic hybrids enhance off-highway machinery, construction and agricultural equipment, material handling and other vehicles in reducing emissions and fuel consumption and improving power distribution. These hybrid systems enhance efficiency by providing closed-loop energy conservation, essentially recycling energy while a vehicle is braking or decelerating.
4. Lightweight and Miniaturized Components
Material advancements provide lighter-weight components and new manufacturing techniques, enabling more compact hydraulic components. Miniaturization of some hydraulic systems allows them to be integrated into smaller devices, such as aerospace components, robotics, hybrid mobile equipment and other applications with weight and space limitations. Durable, lightweight composite materials are what is typically used for strength and durability in creating lighter weight and smaller components.
5. High Performance Lubricants and Materials
Advanced materials and lubricants are an ongoing area of innovation in hydraulic technology. High-performance lubricants, coatings and seals reduce friction and increase the service life of components. Specialty alloys and material composites enhance corrosion resistance and durability, allowing hydraulic systems to perform better in the most demanding applications. In addition, newer additives extend the life of the fluids and components, and bio-based hydraulic fluids reduce negative environmental impacts.
6. Hydraulic System Safety
Taking safety measures is imperative when operating hydraulic systems. Innovations in safety have proved effective when incorporating advanced monitoring systems, pressure relief valves, check valves and other devices to avoid accidents and ensure safe system operation.
Conclusion
