Hydraulic systems have a long and rich history in commercial applications, stretching from ancient Egypt to the present day by means of mediaeval Syria and 18th century London. One of the great things about being an engineer in this field is the way it continually reinvents itself to adapt to changing demands, incorporating the best […]
Compact hydraulic power units are at the forefront of many industrial hydraulic applications due to their high performance and energy efficiency. These small, self-contained systems generate fluid flow to provide power to various hydraulic systems, and each compact power unit typically includes a motor, a hydraulic fluid reservoir, and an integrated pump, all designed in […]
Compact hydraulic power units are self-contained devices used to generate and regulate the flow of pressurised hydraulic fluid within a fluid power system, which is then transmitted through hoses for use in controlling machines. In this article, we will outline the different components of a compact hydraulic power unit, discuss motor options for these units […]
Smart fluid power systems can drive efficiency savings and improve flexibility and visibility for hydraulic and pneumatic systems, so that manufacturers can identify the location of the actuator at any stage of the process. With readily available feedback and diagnostic information, it’s quicker to enact repairs and complete troubleshooting as required.
Although demand for mobile electrification is gathering pace, the hydraulics industry has, so far, largely resisted change. However, a need for clean renewable energy sources and continued evolutions in electric technology has pushed the issue to the top of the agenda, with Doosan Bobcat showcasing its all-electric Bobcat T7X compact track loader at the CES […]
If you’re an engineer responsible for hydraulic systems, you know how important it is to keep them running an acceptable temperature and to take steps to avoid overheating. Overheating can cause catastrophic systemic failures if left unaddressed. In this article, we discuss some of the most common causes of overheating and provide tips on avoiding […]
Modular valves are found in almost every hydraulic system in use today. Like all hydraulic valves, they make sure the fluid inside the circuit flows the right way. Controlling the direction, rate, and strength of the flow of hydraulic fluid around the machine’s circuit is critical to preventing overloading, under-pressured lines and lifts, and fluid […]
Every powered hydraulic machine generates ambient heat. Heat dissipates throughout the system, creating a broadly equivalent level temperature. It’s both a benefit and a hazard to engineers and designers working with volatile, sensitive mechanical systems. While the wasted thermal energy from moving hydraulics helps prevent freezing, rusting, and jams, hydraulic warmth also needs to be […]
Compressed air systems offer many advantages, including improved economy, reliability, and energy efficiency. Their ease of use and versatility enable complex tasks to be completed more quickly compared to other power tools so, when technical problems occur, time, productivity and energy can be wasted. Fortunately, some of the problems that affect compressed air systems are […]
Hydraulic and pneumatic systems both use kinetic motion to move heavy loads. Hydraulics use confined water or oil, and pneumatics use a confined gas, typically air, to generate kinetic motion to drive cylinders and rams. Motion and pressure are converted and multiplied through confinement and precise direction into an intense push. While the two processes […]
