Hydraulic machinery are machines and tools which use fluid power to do work. Heavy equipment is a common example.

In this type of machine, hydraulic fluid is pumped to a high pressure and transmitted throughout the machine to various actuators. The hydraulic pumps are powered by engines or electric motors. Online shopping for tools & hardware from a huge selection of garden tools, power
tools, cordless tools, woodworking tools, hand tools, automotive tools. Pressurized fluid is controlled by the operator with control valves and distributed through hoses and tubes.

The popularity of hydraulic machinery is due to the very large amount of power that can be transferred through small tubes and flexible hoses; and the high power density and wide array of actuators that can make use of this power.

Hydraulic power

The science of Fluid pressure provides some of the theory of hydraulics.

Hydraulic machinery offers a large amount of power and force with relatively small components. A typical hydraulic cylinder with a 75 mm (3 inch) bore, for example, can supply 89 000 N (20,000 lbf). The power transmission in a hydraulic system is easily controlled with valves.

Some parts of a hydraulic system will operate at about 2000 kPa (300 psi) (pilot controls, vehicle brakes).
