Most people understand the basic principles behind hydraulic pressure, but few people understand science. If you look up at the word "Hydraulics", you are likely to encounter many scientific terms.
In fact, science can be decomposed as follows:
When a force is applied to a fluid whose density does not change under pressure, the force is uniformly distributed throughout the entire fluid. As a result, pressure can be applied to small openings and transmitted through liquid to large openings to move large pieces of equipment.
It's very likely that you want to know how a small piece of force can move a thick steel plate, or perhaps the entire car. This is due to hydraulic multiplication.
When the fluid moves from a smaller region to a larger region, the force doubles. Many. As a result, pressure can move large objects.
It is precious in our society. Some daily uses include:
Toilet
Dishwasher
Elevator
Roller Coaster
As you can see, the hydraulic system affects everything from daily needs to entertainment.
1. Automotive industry
If you have a car, you use hydraulic devices every day while driving.
Today's cars use hydraulic pumps, brakes, and motors to take you from point A to point B. For example, the brake uses the pressure on the brake fluid to press the piston onto the brake pads, causing you to stop.
If you want to know, the hydraulic system has also led to an unfortunate trend of low-speed driving and jumping cars.
But the entire process of manufacturing cars also uses hydraulic presses, which are metal stamping.
When manufacturing cars, hydraulic machines mold metal plates into appropriate shapes. By utilizing the power behind hydraulic pressure, they trim, shape, emboss, and manufacture the components required for automobiles.
Without a hydraulic system, making cars is indeed difficult.
2. Aerospace industry
Every time an aircraft takes off or lands, hydraulic devices are used. In fact, they are crucial for aircraft flight.
The science behind Pascal's principle is that the pressure on a fluid is uniformly distributed throughout the entire fluid, which is useful for large equipment such as those used on airplanes. It can include compact, lightweight, reliable, and affordable systems - ideal features for those preparing to fly.
Therefore, the hydraulic system is responsible for activating the landing gear, using flaps and using brakes.
The basic aircraft system includes:
Pumps for power generation
Drive the cylinder and correctly position the components
A heat exchanger used to maintain hydraulic oil at the correct temperature
A pressure reducing valve to avoid the danger of involving too much pressure
Storage containers for storing fluids
These components work together to ensure the internal Functional safety and reliability of the aircraft.
3. Marine Applications
We have covered both automobiles and airplanes, so it is not surprising that hydraulic technology is also used in the marine industry, especially for ocean going ships.
Have you ever thought about why it doesn't require much force to rotate a cruise ship or a large ship? Hydraulic pressure is a secret.
Most ships use a two part system consisting of a cylinder unit and a rudder unit. Every time the wheel is turned, hydraulic oil enters the cylinder in one of the two lines, and the cylinder retracts or pushes a rod according to the direction of the wheel.
4. Construction work
Without customized hydraulic devices, large-scale construction projects are impossible. They are almost used for large machinery.
For example, a backhoe excavator uses hydraulic devices to lift a large amount of dust or debris. The driver pushes the oil, which allows the bucket to lift heavy objects. Without backhoes, even small projects can take weeks to complete.
Hydraulic pressure is even used as a prop to support unstable walls or roofs.
In addition to backhoes and props, hydraulic systems in the construction industry are also used for brick molding machines, shear elevators, concrete pumps, excavators, and more.
The hydraulic system has completely changed the construction industry, allowing teams to complete tasks in a short period of time and reducing labor.
5. Agriculture
The food we eat requires dedication, long hours of work, and appropriate equipment to enter our plates.
But without the beloved three point suspension, where would the farmers be (and our stomachs)? This device is responsible for connecting the device to tractors and other tractors.
The hydraulic cylinder in the hook allows the arm to move accordingly, allowing for connection to the machine.
Without this convenient accessory, it would be a waste of countless time and energy.
6. Die casting
Die-casting formed the metal components we use today. Under high pressure, molten metal is forced into a reusable cavity to conform to the desired shape.
There are several types of machines used in die-casting machines, and hydraulic presses are one of the most popular machines. For safety reasons, mechanical locking is in place during the casting process.
Hydraulic cylinders or direct hydraulic pressure are used to perform this operation.
7. Entertainment
We mentioned roller coasters before, but have you ever thought about how the evil witch of the West disappeared so easily in a burst of green smoke?
You guessed it right: hydraulic.
Hydraulic technology is used in the entertainment industry for applications from hidden platforms or collections to special effects. In fact, the 1976 version of King Kong relied on electro-hydraulic technology to move the towering apes.
