Linde Hydraulics is a manufacturer of heavy duty drive systems consisting of hydraulics, power transmissions, and electronics.The company's product offerings include hydraulic pumps and motors, directional control valves, power transmissions as well as peripheral electronics and software.
Fluid flow in an external gear pump. A hydraulic pump is a mechanical source of power that converts mechanical power into hydraulic energy (hydrostatic energy i.e. flow, pressure). Hydraulic pumps are used in hydraulic drive systems and can be hydrostatic or hydrodynamic. They generate flow with enough power to overcome pressure induced by a ...
Common types of hydraulic pumps to hydraulic machinery applications are: Gear pump: cheap, durable (especially in g-rotor form), simple. Less efficient, because they are constant (fixed) displacement, and mainly suitable for pressures below 20 MPa (3000 psi). Vane pump: cheap and simple, reliable. Good for higher-flow low-pressure output.
The stroke of each piston is caused by an eccentric drive shaft or an external eccentric tappet (e.g., stroke ring). When filling the workspace of the pumping pistons from "inside" (e.g., over a hollow shaft) it is called an inside impinged (but outside braced) radial piston pump (picture 1) .
Klimov TV3-117 turboshaft engine. The accessory drive is the large casting on the top. The accessory drive is a gearbox that forms part of a gas turbine engine. [1] Although not part of the engine's core, it drives the accessories – such as generators, pumps for fuel and lubrication oil, air compressors, hydraulic pumps and engine starters – that are otherwise essential for the operation ...
Later, as hydraulic technology improved, hydrostatic transmissions were introduced for use on swathers but later this technology was applied to combines as well. This drive retained the 4-speed manual transmission as before, but used a system of hydraulic pumps and motors to drive the input shaft of the transmission.
