From Backhoes To Robotic Arms — Five Facts About Hydraulic Equipment

Hydraulic Equipment

Construction sites. Car service centres. Laboratories. Airplanes! Hydraulics — it is all around you (kind of like love). It is the system that allows machines to lift things human beings cannot possibly lift on their own, and move them about. It is the power that drives virtually every piece of machinery modern man uses. And yet, what do you really know about hydraulics?

Hydraulic Equipment

But first, what is the concept behind the hydraulic equipment? The system is basically driven by the idea of force applied to one point, which is then transmitted to another point with the use of incompressible fluid. The force is applied multiple times in the process, and this allows for multiple machining operations. Here are five other facts about this wonderful invention.

1. The hydraulic fluid used for hydraulic systems is usually a mix of mineral oil polyalphaolefin or organophosphate ester. Other compounds may also be used. Petroleum-based oils, which are the most common hydraulic fluids used in ships (but are also used in brakes, control mechanisms, submarines, etc.), reportedly contain the ideal properties of hydraulic fluid. However, it is flammable and when subjected to a highly pressurised environment, it can be explosive.

2. In spite of its size, hydraulic machinery produces great power. One notable example of its strength is through space shuttles. A shuttle is built with two rocket boosters, which are critical during the first two minutes of powered flight and they come with hydraulic components. Each booster is engineered with independent hydraulic power units, with its own auxiliary power unit, hydraulic reservoir, hydraulic fluid manifold assembly, fuel supply module, and pump.

3. Hydraulic machinery runs or operates with a few other components, such as actuators, pumps, valves, and filters. In order for these components to perform according to their functions (i.e., check valves prevent backflow of fluid, the filters take out damaging chips and particles from the fluid), the nuts and bolts that hold them together have to be in good condition. Heavily corroded nuts may be removed safely with a hydraulic nut splitter, which can take hold of the damaged nuts without nicking the bolt as well as stud threads.

4. Hydraulic power is essential in industrial facilities where they drive the movement of automated components. Some machines that run using hydraulics are robotic arms, industrial hammers, pullers, presses and lathes, and others.

5. A majority of heavy construction equipment also uses hydraulic system. Other than lifting equipment, hydraulics is also used in diggers, skids or loaders, and many other types of machinery.
