Pump-turbine

This moveable test stand bases on a pump-turbine with variable, during run adjustable blades in rotor and stator. The Centrifugal pump in the circle is the feeder-pump. It serves also as restrictor and operates as a (non-perfect) centripetal turbine. Flow (Cavitation)- observations can be made through the perspex pipe section. The 4-quadrants frequency speed control for the axial- and radial-machine makes a restrictor valve dispensable and allows axial pump performance near zero pressure.

Measuring systems:

The measuring devices are digitally connected to the internal controller, sending serial data to the comprised portable PC. Stand control and data acquisition is performed by Windows-software. Measured quantities are:
  • Torque of the axial engine with strain gage sensor on the swivel engine
  • Rotational speeds
  • Volume-flow
  • Pressures
  • Electric energy consumption and production for both machines
