Definitions

  • a hydraulic servomotor is located in the rotating system of the turbine, pump or propeller. This servomotor is operated by means of a control valve which can be located either in the rotating system or outside the rotating system.
  • control valve is located in the rotating system, concentric with the axis of rotation and in close proximity to the servomotor.
  • the valve close to the servomotor it is deep down in the shafting so that access to the control valve and its liner for inspection and overhaul is difficult, and any means for direct mechanical indication of the actual runner blade setting is complicated.
  • valve and liner are easily accessible and the means for direct mechanical indication of runner blade position are relatively simple, but these constructions occupy a great deal of space and are expensive as compared with designs in which the control valve is located in the rotating system.
  • the present invention relates to an improvement in runner-controlled hydraulic turbines, pumps or propellers in which the pitch of the runner blades can be varied by means of a hydraulic servomotor in the runner hub or in the shaft carrying the runner hub, and the control valve is located concentrically in the rotating system in or adjacent to the upper part of the shaft and is mechanically connected to the servomotor in such a manner that direct mechanical indication of runner blade setting is obtained.
  • the turbine includes a turbine runner or propeller -1 attached to a drive or driven shaft 2, which is mounted in a thrust bearing 3 and a guide bearing 4, which may be of the sleeve type, as shown, or of the antifriction ball or roller type.
  • a hydraulic servomotor consisting of a cylinder 5 forming a part of the runner casing and a piston 6 is housed in the runner 1.
  • the piston 6 is connected to the variable pitch runner blades 7 by means of a piston rod 8, a crosshead 9 fixed to the piston rod and links 10 pivotally connecting the ends of the crosshead 9 to levers 11 extending substantially radially of the propeller blade hubs to afford a means for rotating the blades around their axes to change their pitch.
  • a combinator 12 which is mounted on the upper wall of an oil pot or reservoir 13.
  • a control slide valve plug 14 is mounted in a slide valve sleeve 15 having a peripheral piston 16 thereon slidable in a cylinder 17 supported by the oil pot 13.
  • a lower pipe 18 and an upper pipe 19 communicate with the cylinder 17 on opposite sides of the piston 16.
  • Pipe 19 is connected to a regulating slide valve 20, which is provided with an inlet pipe 21 and an exhaust pipe 22 connected to an oil pan or sump 23.
  • a slide valve plug 24 in the valve 20 is movably attached to the control valve sleeve 15 by means of a lever 25 and a restoring link 26.
  • Lever 25 rests by gravity on or is otherwise biased against a cam 27 which can be controlled by means of a connecting rod 28.
  • a passage 29 in the sleeve 15 connects the lower part of the cylinder 17 to an annular space 30 between the sleeve 15 and the slide valve plug 14.
  • Two internal annular collars 31 and 32 in the sleeve 15 are located so that they can close two ports 33 and 34 in the valve plug 14.
  • the plug 14 is rigidly attached to the servomotor piston 6 by means of two pipes 35 and 36.
  • Pipe 35 forms a flow passage between the port 33 and the space below the piston 6 in the cylinder 5.
  • the space between pipes 35 and 36 forms a passage between the port 34 and the space above the piston 6 in the servomotor cylinder 5.
  • a pointer 37 is fixed to the valve plug 14 and is disposed adjacent to a matching scale 38 fixed in the top of the'oil pan or sump 23 for indicating the setting of the rod 14 and thereby also the setting of the piston 6 and the pitch of runner blades 7.
  • Different height levels of the control valve sleeve 15 correspond to different mutually fixed positions of the parts to which it is mechanically connected, namely the restoring link 26, the lever 25, the cam 27 and the valve rod 24 of the regulating valve 20. If the cam 27 is turned clockwise by means of the connecting rod 28 so that it lifts the lever 25, valve rod 24 is moved upwardly and communication is established between the pipe 19 and the exhaust pipe 22 allowing oil or other liquid in the system to flow from the cylinder 15 above the piston into the sump 23.
  • the pointer 37 indicates the pitch of the runner blades 7 directly on the scale 38.
  • the control system may include other fluid flow connections than those described above.
  • an overflow pipe 39 returns oil from the sump 23 to the reservoir or pot 13 and an oil return pipe 40 returns oil leaking from the cylinder to the reservoir13 or supplies oil to the linkage in the turbine runner, as may be required.
  • control system described above can be used with an engine driven propeller, for example, for use for propelling boats, ships and the like, or it may be used in turbines and the like wherein flow of fluid around the runner develops power for driving other mechanisms. Appropriate driving connections will be made to the propeller shaft 2 as may be required.
  • a control and indicating system for adujsting the blades of turbine, propeller and pump runners and the like comprising a runner having adjustable blades mounted thereon, a tubular drive shaft supporting said runner for rotation, a servomotor in said runner including a cylinder and a first piston movable in said cylinder, means connecting said first piston to said blades for adjusting said blades in response to movement of said piston, a slide valve in axial alignment with and outside of the end of said shaft remote from said runner, said slide valve including a valve plug movable relative to said shaft and a slide valve sleeve slidably receiving said plug and movable relative to said shaft and said plug, conduits extending lengthwise in said tubular shaft and having passages controlled by said plug and sleeve connected to said cylinder at opposite sides of said first piston, said plug and sleeve in one relative position preventing flow of fluid through said passages, and in other positions admitting fluid to said cylinder on one side of said first piston and discharging fluid
  • a control and indicating system for adjusting the blades of turbine, propeller and pump runners and the like comprising a runner having adjustable blades mounted thereon, a tubular drive shaft supporting said runner for rotation, a servomotor in said runner including a cylinder and a first piston movable in said cylinder, means connecting said first piston to said blades for adjusting said blades in response to movement of said piston, a slide valve in axial alignment with and outside of the end of said shaft remote from said runner, said slide valve including a valve plug movable relative to said shaft and a slide valve sleeve slidably receiving said plug and movable relative to said shaft and said plug, conduits extending lengthwise in said tubular shaft and having passages controlled by said plug and sleeve connected to said cylinder at opposite sides of said first piston, said plug and sleeve in one relative position preventing flow of fluid through said passages, and in other positions admitting fluid to said cylinder on one side of said first piston and discharging fluid from the
