Most engineering students share the same career goals of joining industry leaders like Tesla, SpaceX, or GE. Big companies like these are filled to the brim with hydraulic actuators in their inventions. Knowing how these tools work is key to impressing these employers.
Look no further than our guide for all the knowledge you’re after. Let’s explore this basic tool that will help you shine in your future career.
What Are Hydraulic Actuators?
Hydraulic actuators work by using fluid pressure to create mechanical motion. They have a type of liquid called hydraulic fluid.
When you push or pull the control, it changes the pressure of this fluid. This change in pressure is what causes movement.
The system also includes a control valve. You can think of the control valve as the manager of the pressure. It tells the hydraulic fluid where to go and how much pressure to apply.
Their Relevance in Hydraulic Systems
Hydraulic actuators are essential in hydraulic systems, converting fluid pressure into mechanical motion, which is crucial for applications requiring precise control over heavy loads. They act as the system’s muscle, enabling significant force application in a compact form, essential for machinery in the construction, industrial, and aerospace sectors.
The efficacy of hydraulic systems also depends on the harmonious operation of their components, including pumps, valves, and actuators, which ensure optimal performance. Actuators, in particular, play a vital role by transforming controlled fluid movements into direct mechanical actions. Incorporating custom parts is paramount to enhancing hydraulic system performance, as they are specifically designed to meet the unique demands of an application that standard components cannot.
As another example of such parts, custom hydraulic hoses are tailored to suit specific system configurations and pressure requirements, significantly reducing the potential for leaks and improving system reliability. These tailor-made components ensure better system integration, minimizing inefficiencies.
Custom-designed actuators and parts can withstand unique pressures, temperatures, and corrosive conditions, enhancing system reliability and longevity. The innovation in custom parts leads to more compact, powerful, and energy-efficient hydraulic solutions. Offering precise solutions and customized parts, alongside custom hydraulic hose, improves the system’s overall efficiency and functionality.
Engineering Applications for Hydraulic Actuators
The beauty of hydraulic actuators is that they’re not limited to one use; they can be used in a myriad of engineering applications. These devices are perfect for situations requiring precise control, such as industrial distribution or heavy machinery. These actuators are also for products that need lots of strength, like construction equipment or airplanes.
They can produce different types of movements, including straight lines, round-and-round, or back-and-forth. Because of this, you can find these handy tools in things like baling machines, cranes, digging machines, shovels, and pressing machines.
Linear hydraulic actuators, in particular, provide a high force-to-weight ratio. This makes it a great choice for cranes, loading trucks, and drilling machines.
Types of Hydraulic Actuators
Linear hydraulic actuators produce linear motion. Even though this might seem limiting, these types of actuators can be applied in many different ways. Their primary function is to push or pull along a straight line.
They deliver high force output and precise motion control, making them suitable for heavy-duty industrial applications.
Cylinders are the most common type of linear hydraulic actuator. They provide linear motion by containing the pressurized hydraulic fluid within. This pushes the piston and, in turn, moves the load.
This type of hydraulic actuator outputs rotational motion. Rotary actuators are mostly used when angular motion is required. They have a limited angle of rotation, typically 90, 180, or 360 degrees.
There are two common types of rotary hydraulic actuators. Vane actuators work by trapping fluid between a vane (or blade) and the inside surface of a cylinder. Rack and pinion actuators use a cylinder with an integral piston and rack.
