Kayrakkum Dam (Russian: Кайраккумская ГЭС; Tajik: НБО Қайроққум), also spelled differently as Kayrakum, Kairakum, Qayraqqum or Qayroqqum, is a dam on the Syr Darya River near the city of Kayrakkum in Sughd Province, Tajikistan. It is located on the western edge of the Fergana Basin and forms the Kayrakkum Reservoir. The reservoir supplies water for irrigation, mainly in Uzbekistan in the lower reaches of the river, and for the production of hydropower. The power plant has an installed capacity of 126 MW and is operated by the state-owned operator Barki Tojik. Construction of the dam began in 1952. Six units with Kaplan turbines were commissioned in 1956 and 1957. The power plant is currently undergoing modernization and renovation, aimed at increasing the power plant’s capacity from 142 to 174 MW.
At the invitation of GE, the supplier of new turbosets, we perform machining on subsequent six blocks.
We have just finished work on unit 5, the second of six being machined by ours. There are four more blocks ahead of us.
In the scope of machinig:
- machining of the upper and lower ring, faces and cyllindrical surfaces, as well as drilling and threading of holes in the lower ring,
- machining of the spherical part of the rotor chamber.
All these machinings are carried out using the machine tool of our design KWW525.
Workplace and installation of the KWW525 machine tool:
Machining of the spherical are: this was the case – the old surface, destroyed by many years of exploitation and subsequent stages of processing, up to the final result.
Particularly noteworthy is the concern of the Ordering Party – the GE-Kobra consortium – for the safety of work, including regular training and exercises.
