Gear Hydraulic Pump

gear hydraulic pump
    hydraulic pump
  • Hydraulic pumps are used in hydraulic drive systems and can be hydrostatic or hydrodynamic.
  • a water pump that uses the kinetic energy of flowing water to force a small fraction of that water to a reservoir at a higher level
  • a device that converts mechanical force and motion into fluid power.
  • One of a set of toothed wheels that work together to alter the relation between the speed of a driving mechanism (such as the engine of a vehicle or the crank of a bicycle) and the speed of the driven parts (the wheels)
  • Equipment that is used for a particular purpose
  • set the level or character of; "She pitched her speech to the teenagers in the audience"
  • gearing: wheelwork consisting of a connected set of rotating gears by which force is transmitted or motion or torque is changed; "the fool got his tie caught in the geartrain"
  • A particular function or state of adjustment of engaged gears
  • a toothed wheel that engages another toothed mechanism in order to change the speed or direction of transmitted motion

Cruquius Gemaal
Cruquius Gemaal
The pumping stations got the names of famous hydraulic engineers: Leeghwater, Lijnden and Cruquius. The construction of the Leeghwater was started in 1845, the construction of the Lijnden and Cruquius began in 1847. For the design of buildings in the Gothic Revival style drew the Dutch public works engineer in January Anne Beijerinck (1800-1874), while the machines were designed by Joseph Gibbs and Arthur Dean of London. The steam engine itself was built by Harvey & Co. Hayle in Cornwall), the pumps by Fox & Co in Falmouth (Cornwall), and poor balance and steam boilers by Van Vlissingen & Dudok van Heel in Amsterdam.
Steering gear - controls
Steering gear -  controls
These controls operate hydraulic pumps, which power the rams to turn the rudder (see next picture). There are two sets of controls, one for each rudder, and they can be cross-connected. Optimally, the controls are run electrically from the bridge, but if that fails, and the connection to the auxillary steering position fails, then the rudder can be manually controlled from here.
