Hydrokinetic drives are typically rated from 1 to 5,000 hp but higher ratings are common.
Any fluid system may need to measure pressure, flow, or fluid level.
Sometimes the complexity and magnitude of a job suggest that a system of separate hydraulic components would be difficult to put into action.
Packings are seals that normally are packed around a shaft or rod and compressed to provide a sealing effect.
To minimize wasted energy in hydraulic systems, variable-displacement pumps were developed.
Water vapor is contained in high-pressure air.
Electrohydraulic servovalves, capable of controlling pressure, flow, or position in proportion to an electrical input, offer unsurpassed performance in a fluid-power system.
Unwanted heat is a problem for all hydraulic systems.
These seals are quite similar to rod and piston seals, but are adapted to rotary motion.
Pipe and tubing are used when rigid lines are preferred.
Actuators convert fluid energy into useful work.
Valves are essential elements for controlling fluid system performance.
Fluid-handling or transfer devices are not basically concerned with the modulation or transfer of power, but only with the movement of fluid.
Intensifiers, also known as boosters, use a large quantity of low-pressure fluid to produce a smaller quantity of higher-pressure fluid.
Hydrostatic drives are widely recognized as an excellent means of power transmission when variable output speed is required.
