HT 990 LOW HEAD HYDRAULIC TURBINE TEST RIG
GENERAL DESCRIPTION

    This test facility was design and developed jointly with The Joint Graduate School of Energy and Environment (five institutions). It is intended to simulate large hydro power plant discharge for end user in designing small low head turbines.

    The test rig provides water flow as well as measuring instruments. Flow is generated by a centrifugal pump. A head tank in front of the test section is provided to simulate a static head and another tank is provided after the test section. Flow rate and head can be varied by an inverter. A flow control valve at the pump discharge and a flow control valve of the return line between pump discharge and pump suction are provided. A dynamometer at the test section measures the designed turbine output.

    The equipment is supplied unassembled and to be erected and commissioned at site.

TYPICAL EXPERIMENTS

    This is an ideal facility to simulate flow conditions of the actual site. The turbine input (flow rate and head) and output (speed and torque) can be accurately monitored. Thus the most efficient prototype turbine can be designed, developed and tested.
