COMPANY OWNER

Water turbines have been produced in the Blansko plant since 1904. During this time CKD Blansko has gained a strong position among suppliers of hydraulic power plant technologies throughout the world.

In autumn 2007, after more than a decade of absence of Small Water Turbine Division in CKD Blansko, a new company was established together with the management of CKD Blansko Holding. The company continues the tradition of manufacturing water turbines and hydro-mechanical equipment for small hydro power plants that CKD Blansko manufactures since 1918. The newly established company is called ČKD Blansko SMALL HYDRO, s.r.o.

The company offers water turbines of all main types such as Kaplan, Francis and Pelton turbines both horizontal and vertical arrangement. Moreover, the company is ready to meet special customer’s requirements and offer reversible (pump) Francis turbines for pump storage plants as well.

ABOUT US

Viktor Kaplan‘s visit at ČKD Blansko

1698 – The owner of the Blansko manor, count of Gellhorns, established the first iron-mill in the Punkva river

valley – origins of engineering manufacturing.

1904 – Origins of water turbines manufacturing.

1985 – A hydraulic laboratory with parameters according to the IEC 60193 standard has been put into

operation. It is used to develop new profiles of Kaplan, Francis and Pelton turbines.

2007 – ČKD Blansko SMALL HYDRO founded.

2010 – Integration to the JSC Tyazhmash Group.

HISTORY

3

The company specializes in manufacturing and supplies of new turbines with output range from 200 kW to 40 MW on turn-key basis (EPC supplies), i.e. supplies of complete electro-mechanical equipment for hydro power plants (turbine with auxiliaries, generator, LV & MV electrical equipment). Supplies of hydro-mechanical equipment such as main inlet valves (of butterfly, spherical or sluice type etc.) as well as manufacture of other equipment for intake or dam structures (slide gates, stop logs, weir flaps, radial gates etc.) is also a part of company’s product range.

Our design pays maximum attention to the customer’s requirements regarding environmentally friendly operation. Thanks to many years of experience we can offer our customers well-proven quality and we are able to meet their most demanding requirements, whether in the efficiency of the machines or in environmental standards.

TURN-KEY PROJECTS (EPC)

4

Basic design department consists of a team of experts with long years of experience with designing of small as well as large hydro power plants.

There are three main tasks of the department:1. Technical support of sales and project management department.

2. Implementation of basic design documentation consisting namely of the following: Execution of layout drawings of the whole electro-mechanical equipment in the powerhouse with relation to civil and electrical part. Execution of civil readiness drawings incl. indication of all forces acting from the equipment to civil structure that serve as a basis for civil designer. Execution of diagrams and description of electro-mechanical equipment control that includes a list and description of functions of all sensors, instruments and actuators, and describes all automatic processes. It serves as a basis for the supplier of LV & MV electrical equipment and control system of the power plant.

3. Participation during erection works, field tests, power plants commissioning and guarantee measurements as well.

BASIC DESIGN DEPARTMENT

5

State-of-art quality and long service life of our equipment is ensured, from the very beginning of design process, by precise elaboration of detail design for manufacturing and selection of the high-quality and suitable materials.

Main tasks of the detail design department are:

1. Elaboration of design documentation for manufacturing.

2. Strength, stiffness and fatigue structural calculations (water turbines, valves, hydro-mechanical structures, etc.) using the following methods: Finite Element Method – FEM (SolidWorks Simulation, Premium software) in order to determine structural stress and strain. Methods of fracture mechanics for evaluation of strength and fatigue life.

3. Elaboration of operating & maintenance instructions.

4. Participation during erection works, field tests, power plants commissioning and guarantee measurements as well.

DETAIL DESIGN DEPARTMENT

Kaplan turbines are suitable for lower hydraulic heads and higher water flows. Kaplan turbine is an axial reaction turbine with combined regulating elements – wicket gates and runner blades. Adjusting of wicket gates and runner blades ensures high turbine efficiency over a wide range of flows.

Head: 2 – 40 [m] Output: 200 – 10 000+ [kW] Diameter: 500 – 3 000+ [mm]

Horizontal or vertical arrangement Spiral case, open-flume, pit, bulb, S-type and Saxo type Fixed or adjustable runner blades and wicket gates 3 – 6 runner blades

KAPLAN TURBINES

Francis turbines are the most common water turbines in use today and suitable for a wide range of heads and flows. Francis turbine is a radial-axial reaction turbine with one regulating element – wicket gates that adjust the water flow through the turbine (runner blades).

Head: 10 – 300 [m] Output: 200 – 40 000+ [kW] Diameter: 400 – 1 700+ [mm]

Horizontal arrangement for smaller units Vertical arrangement for larger units

FRANCIS TURBINES

8

Pelton turbines are used for water energy production in areas with high hydraulic head and low water flow. Pelton turbine is a water impulse turbine.

Head: 70 – 800 [m] Output: 300 – 40 000+ [kW] Diameter: 500 – 1 500+ [mm]

Horizontal arrangement with maximum 2 nozzles Vertical arrangement with maximum 6 nozzles

HYDRO-MECHANICAL EQUIPMENT

11

To meet the growing needs for research and development of water turbines, a new hydraulic testing laboratory was built in the years 1985–1988 that, thanks to its parameters, belongs to the largest one in Europe and satisfies all criteria for development and testing of water machinery. There are four independent measuring circuits in the laboratory (Kaplan, Francis, Pelton and flow meters test stand) for model testing of all types of turbines and hydro-mechanical equipment.

Research and Development in ČKD Blansko Holding, a.s.
