A mouse that has only one hole is quickly caught…
Hydraulics is the transmission of signals, forces, and energy, or for lubrication purposes. The hydraulic block of today’s technology looks almost painfully full of holes; while it might remind the viewer of Swiss cheese, however, the technology behind it is complex and incredibly versatile.
Hydraulics is one method of transmission – an alternative to mechanical gears or electrical or pneumatic transmissions. The power transmission is provided by a hydraulic fluid; this is usually a particular type of mineral oil, but it can also be a more environmentally-friendly option such as water or special ester or glycol fluids. The transmitted forces are a result of the pressure and the amount of fluid streaming through. A distinction can be made here between:
The flow of pressurized fluid into the cylinder forces the piston and piston rod within the cylinder to move; this movement is then used for a given work process and to power machines. Rotating drives, such as the hydraulic motor, can also be implemented using pressurized fluid.
Due to their specific advantages, hydraulic drives are frequently used in mobile machinery such as construction or agriculture machinery, and in particular to lift and shift heavy loads (forklifts, excavators/diggers, elevators, cranes, etc.).
Additional typical uses include:
The list could be extended indefinitely; in terms of part variety and designation, there are more options than holes in a piece of Swiss cheese. From hydraulic blocks to transmission covers and bell housings, a huge variety of components fall under the mantle of hydraulics. The primary material used here is SG cast iron; however, for higher pressure levels, ADI can also be used. No need here for high-temperature materials – it has been reported to us that the hydraulic fluids already have “massive difficulties” at 300° C (575°F)…
We will find a suitable solution.
