Hydraulic systems are used to bring the fluids into motion. Liquids like water are incompressible. We cannot squeeze them. In order to change their motion, the pressure is applied by using hydraulics in the case of fluids and pneumatics in the case of gases. Car breaks are one of the examples of hydraulic systems.
Hydraulic systems are in use because they have many advantages over mechanical and electrical systems. They use liquids to create pressure and uses the applications of Pascal’s law.
Here are some advantages of hydraulic systems that are used in industries:
- Hydraulic systems are easily controlled as only a lever, and push buttons are used to start, accelerate, decelerate, and stop the system.
- Easy control on any machinery makes it easy to use for the workers, which will save their time, making the production process more efficient.
- It is easy to maintain hydraulic systems because they use fewer parts as compared to mechanical and electrical systems that make it easy to sue and sustain. They are simple and economical as they have fewer moving parts.
- The hydraulic systems use oil as the medium of transfer. The moving parts are covered with oil that lubricates them naturally.
- The employees don’t have to put their time and effort to grease its parts for better performance, thus reducing the manual work.
- Whereas the electric and mechanical systems need more attention and workforce for their maintenance.
Constant Torque and Force:
- Only hydraulic systems can provide continuous force and torque (the twisting force that causes rotation).
- Even if the speed of the system keeps changing, the power would not be affected.
- No other system can provide constant pressure despite speed changes.
- The leakages in the hydraulic system can be easily detected. There are five elements in a hydraulic system: the driver, the pump, control valves, and the load. The driver is a type of engine.
- The pump is used to increase pressure. The motor is the counterpart of the pump that transforms hydraulic input into mechanical output.
- Hydraulic systems can multiply the force that helps in lifting heavy objects even with the changes in speed. These systems can use a fraction of pressure to produce tonnes of output.
- Small and flexible hoses and tubes are enough to transmit a large amount of power.
- If more burden is applied, then it will damage the parts of the machinery.
- A valve is used to control the load. When the load is more, the valve adjusts itself according to the load that is to be carried.
The fluid power systems also minimize unnecessary noises that create a disturbance in work and reduces the efficiency of workers. Its easy management is what makes it a desirable option for the industries.
Hydraulic systems are used in every field and industry that includes construction machines, elevators, motors, cars, airplanes. In fact, all the significant aircraft and missiles use these systems because of their advantages over mechanical and electrical systems. Other machines that use hydraulic systems are- cranes, bulldozers, excavators, etc.
