Test Platform
Heki has a test platform designed to perform detailed high-quality studies for developing hydraulic turbines
Platform Characteristics
Heki's hydraulic turbine test platform is located in the heart of the Adrien-Pouliot Pavilion at Université Laval. It occupies an area of 350 m² spread over three floors. The ground floor houses the main reservoir, constructed of waterproofed concrete, with a capacity of 270 m³. The hydraulic circuit test section is located on the third floor.
Test Stand Operation
The test stand can operate in open or closed circuit configurations and can be adapted to different reaction turbines (Francis, Kaplan or bulb) with diameters ranging from twenty-five to fifty centimetres. Its maximal capacities are :
Flow rate (Q) < 1m3/s
Water head (H) < 50m
Turbine rotation speed < 2 000 tr/min
Supplied power (P) < 225 kW
Water is delivered to the turbine through a semi-axial pump driven by a 260-kW variable speed motor. In a closed loop, water in the circuit is maintained at a constant temperature by heat exchangers that use water cooled by Université Laval chilled water plant (CERSO). A vacuum pump depressurizes the downstream tank to control cavitation in the turbine.
