Many systems today depend on hydraulics to perform different tasks. Unlike mechanical systems which need solid components to maneuver other components, hydraulics depends on fluids and the force generated by them.
What’s so special about hydraulics, especially since the same results, pretty much, can be achieved through mechanical, electrical and pneumatic systems? The clear answer is based on the effectiveness of fluids and how they are able to turn a relatively weak pump or similar component into one which generates force often the initial amount.
Pros of hydraulic systems
Fluids flow smoothly and this feature is placed on systems and heavy equipment. The force generated by hydraulics produces very smooth movement which is invaluable in applications where jerky motions can not be tolerated.
Another feature of such a system is load-bearing capacity. Unlike pneumatic systems that depend on compressed gas, hydraulics is able to ΥΔΡΑΥΛΙΚΟΣ ΑΘΗΝΑ bear much heavier weights as it’s incompressible. It does it smoothly too, something pneumatic systems can’t achieve as the air pressure alters with cylinder movement and load changes. Moreover, the total amount of force required to generate the same produced by a hydraulic system is a lot more. This can translate into higher expenses as larger and better components carry heftier price tags.
In terms of energy, hydraulics uses much less when compared to others like pneumatic systems. Heat loss can also be less meaning not much energy is employed to generate the required force. Since such systems are normally utilized in large scale applications in settings like factories and plants, it becomes vital that you cut corners without compromising quality and production volume. Hydraulics allows this while combining all of those other benefits mentioned above.
Cons of hydraulics
Where there are numerous benefits to using hydraulics there’s also cons. This shouldn’t be a deterrent but should rather give us an comprehension of things to expect.
Since hydraulics depends on fluids, there’s a possibility of leakage. Not only does this reduce steadily the efficiency and power of the device but it causes a mess. Since many systems and components require clean environments and surroundings, there’s a chance that the leaking fluid might cause damage and fire hazards. Bear in mind, however, that since this can be a known fact, steps are always taken to ensure that accidents don’t occur. The hydraulic systems themselves are made in this way that they pose little danger to you and to components even during leakage.
The fluid utilized in these systems must certanly be clean as contaminants can clog pipes. However, it’s possible that pollutants can enter in which case efficacy can be reduced. The surroundings or setting must, therefore, follow strict sanitary standards during all points of the manufacturing process.
Like all systems, hydraulics has its benefits and drawbacks. But at the same time where bulky components are beginning to be edged out in favour of smaller and more effective systems, hydraulics trumps. Pneumatic and electrical-based machines and components work very well too but they might need an increased source of power or larger pumps to generate the same number of force given out with a hydraulic system. For manufacturers and users requiring such high output, it’s more cost-effective to depend on hydraulics. Production time is reduced as efficiency maintains a high average.
