Bench for Testing Kaplan Turbines and Combined Pump-Turbine Units

Description

The versatile flow bench for testing hydraulic machines (hydraulic turbines, pumps, micro hydropower units and their components) is a unique construction with a system of tanks, pipelines, circulation pumps, electrical machines, computation-measuring complex and auxiliary equipment. It is made as closed-circuit hydraulic system and intended for investigating working procedures and conducting complex experimental tests of the models of hydraulic machines including approval tests in compliance with requirements of international standard IEC 60193.

In the process of testing models of hydraulic machines measurements of necessary parameters and processing of results are performed automatically by computation-measuring complex.


Innovative Aspect and Main Advantages

  • Head when testing turbine models, m  ––––––––––––––––––––––––– 5 to 15
  • Rotational frequency when testing hydraulic machines, min-1 –––––– 800 to 1,200
  • Maximum flow rate, l/s ––––––––––––––––––––––––––––––––––––– 750
  • Diameter of a rotor wheel model, mm ––––––––––––––––––––––––– 350-380
  • Total relative error in defining net efficiency, % –––––––––––––––––– ±0,25

IIn 2006 laboratory bench of hydraulic machines of IPMash NAS of Ukraine obtained a status of national patrimony.


Areas of Application

IPMash NAS of Ukraine has developed and investigated several models of flowing parts for hydraulic turbines and combined pump-turbine units including for Kahovskaya, Dneprodzerzhinskaya, Kievskaya HPS (Ukraine), Viluyskaya HPS (Russian Federation), Shamhorskaya HPS (Azerbaijan), Thak-Ba HPS (Vietnam), modernization of Kievskaya pumped storage plant, and also Dnestrovskaya pumped storage plant. In 2008 together with “Kharkovturboengineering” approval tests of axial-flow turbine model for HPS San-Joan (Brazil) have been conducted.
