Hydraulics are complicated. These systems are comprised of many of different components and while they all seem to do different things and contain different specs, the basic principles behind them are all the same. Here’s 15 fascinating facts about hydraulics:
#1 : Hydraulic equipment is comprised of four components. There is a reservoir to hold the fluid, a pump to drive the hydraulic press fluid through the system, a valve to monitor pressure and flow, and a cylinder that transfers the fluid into actual energy.
#2 : Without the buildup of pressure, no power would be generated by the hydraulic system. The oil contained in the system under intense pressure levels is what actually products energy.
#3 : Nickels, pennies, quarters and dimes are made on hydraulic presses.
#4 : The power in hydraulic systems is almost always generated from mechanical power.
#5 : Hydraulic energy comes in three types. There is potential energy, which is also known as pressure energy. Kinetic energy is the energy derived from moving liquids, and heat energy is what results from the resistance of flow, otherwise known as friction.
#6 : All energy that is put into a hydraulic system must come out. This will either come out as work/gain or heat/loss.
#7 : Hydraulic systems do not create new energy. They simply transform existing energy into a different form.
#8 : Oil is pushed through the hydraulic system, not pulled. This is a common misconception, but now you know!
#9 : Hydraulic systems are made differently. There are two types – open center systems and closed center systems. Closed center systems feature a constant pressure with varied flow, while open center systems have a constant flow, but varied pressure.
#10 : There are two types of hydraulics that you can use. Hydrodynamics use fluids at a low pressure and higher speed, while hydrostatics use high pressures at low speeds.
#11 : Having unrestricted flow for you hydraulics is essential. If the flow becomes blocked, the systems pressure will drop immediately and cause problems.
#12 : The oil in your hydraulic system will always take the path of least resistance.
#13 : Contrary to their name, pumps do not pump pressure, they create flow. Pressure is created by a resistance to flow.
#14 : The oil in your hydraulic equipment must be confined to create enough pressure for work. It is essential to have a tightly sealed hydraulic system.
#15 : Hydraulic power output is most often achieved by converting back to a mechanical power. An example of this is a cylinder that raises a weighted object.
