Definitions

  • the present invention comprehends a turbine driven pump wherein the rotary of the turbine is preferably mounted on the impeller of the pump. By directing the discharge of both the turbine and pump into a substantially axially disposed outlet an ejector eflect is created which enhances the efficiency of the unit.
  • the two fluid streams intermix and for maximum efficiency turbine discharge is preferably in an outward (radial) direction and the pump impeller discharge is at some angle to it and in the direction of shaft rotation.
  • the velocity of the liquid leaving the turbine is higher than that of the pump impeller and creates an ejector effect.
  • the kinetic energy of the turbine which otherwise would go to waste is being utilized to improve the efficiency of the unit.
  • stationary axle hydrostatic type bearings which provide for inexpensive and simple pressure pocket construction in form of milled flats on the axle.
  • a simple bearing bushing of a hydrodynamic type is preferable used with the additional advantage of a fully floating rotor in a stationary or slow running speed condition.
  • the bearing design is such that it allows the impeller pressure balance slots (holes) to be used for the bearing discharge passages thus further simplifying construction.
  • a special diffusion velocity schedule which allows turbine inlet passage to intersect the combined turbine and pump discharge without high dynamic-head losses.
  • the flow velocity is decreased progressively to a low value so that the liquid can pass around the obstacle formed by the inlet passage and then uniform acceleration is introduced to meet the outlet flange size requirements.
  • the dummy inlet can be utilized as a clean water pocket for cyclone cleaning apparatus supply, to avoid high dirt concentration should it occur during the start up.
  • the pump inner chamber acts as a settling tank, during the periods of idleness.
  • the internal components can be fitted into different type single cast body should a specific pipe arrangement require such a change.
  • the radial forces on the bearings are reduced to a minimum by incorporation of the internal components in a double volute casing.
  • liquid lubricated bearings may be replaced by pro-sealed ball bearings which are shown as enclosed in a cartridge which also contains a mechanical seal.
  • the water lubricated bearing supply passage may be used as clean liquid supply for the mechanical seal.
  • an external bearing lubricating supply pipe may be installed providing means for pump cleaning after long periods of idleness where dirt and debris sediments can be expected.
  • two different fluids may be used and particularly where mixing is desired. Or in a situation where the fluids may be separated after mixing by using for example, a cyclone centrifuge or where separation will occur in a settling tank.
  • a gas and liquid combination is also possible; for example, provisions may be made for driving the turbine by steam where the steam will condense and mix with water. In such an installation the gas bubbles increase the liquid head in the vertical discharge of the pump.

  • a diffuser means 52 is incorporated into the unit and blades 54 of the diffuser turn or blend the turbine discharge so that it follows the pumping means discharge.
  • the ejector vanes 54 may be formed as part of the diffuser or separate as is shown in FIGURE 13 wherein they are designated 54'.
  • the diffuser serves an additional purpose in the present arrangement as follows:
