Features of the Kaplan ASUMB turbine

The ASUMB Kaplan turbine is designed for operation at heads of 2–30 meters and a wide range of flow rates. Adjustable runner and guide vane blades maintain high efficiency of 88–93%, making it an optimal choice for gentle rivers, diversion schemes, and microhydropower plants.

Benefits and effectiveness

High efficiency at low and medium pressures
Efficient operation with seasonal fluctuations in water consumption
Versatility for small and medium-sized hydroelectric power plants
Suitable for modernization of old Soviet hydroelectric power plants

Automatic regulation and adaptability

The ASUMB system synchronously controls:

impeller blade angle
position of the guide vane

Benefits of automation:

stable generation of electricity all year round
minimization of overloads and losses
adaptation to seasonal changes in flow rate without manual intervention

Reliability and durability

The turbine design includes:

reinforced impeller blades
anti-corrosion coatings
precision bearings
cavitation protection

The service life of the equipment reaches 40–60 years with proper operation.

Ease of maintenance and operating costs

Maintenance of the ASUMB Kaplan turbine does not require complex hydraulics. Basic operations:

impeller blade inspection
checking the guide vane
diagnostics of the automatic hydraulic system
bearing inspection

Routine maintenance is carried out every 12–18 months, and major repairs are carried out every 12–20 years, which reduces operating costs.

The principle of operation of the Kaplan turbine ASUMB

Water enters through an adjustable guide vane.
The stator blades form an optimal flow direction.
The flow acts on the impeller, where the blades automatically change their angle of inclination.
The energy of the water is transferred to the shaft, driving the generator.

This adaptive scheme ensures high efficiency even on rivers with unstable water flow.

Where are ASUMB Kaplan turbines used?

Small and medium-sized hydroelectric power plants
Diversion stations
Modernization of old Soviet hydroelectric power plants
Urban and rural micro hydroelectric power plants
Autonomous energy facilities for enterprises

Particularly relevant for the regions: Kazakhstan, Kyrgyzstan, Uzbekistan, Georgia, Armenia, Russia (Siberia, Altai), Caucasus.

Project cascade mini-hydroelectric power station on the river Arym

Project objective: to construct a cascade of mini-hydroelectric power plants on the Arym River to generate clean electricity and sell it at a "green tariff." 🌊 1. General concept: The Arym River has a natural elevation difference, making it ideal for a cascade of mini-hydroelectric power plants. The hydrological regime is snow-glacial: the maximum flow rate is up to 7 m³/s during the melting period, and the minimum is about 1.3 m³/s in winter. A single pressure penstock with a diameter of 1400 mm and a flow velocity of approximately 3 m/s is used, providing an average annual operating flow rate of 4.62 m³/s. ⚙️ 2. Cascade structure: The cascade consists of four stages, each with its own pressure head and diversion length. The effective total head of the cascade is ≈1065 m, with total losses of only 38.9 m. No. Name Effective head, m Capacity, MW 1 Arym-1 ≈254 ≈11.0 2 Arym-2 ≈224 ≈9.6 3 Arym-3 ≈195 ≈8.4 4 Arym-4 ≈392 ≈11.7 Total: ≈40.7 MW ⚡ 3. Energy potential The total installed capacity of the cascade is about 40.7 MW. Turbine equipment has an efficiency of up to 85%, which guarantees high efficiency and stable generation. 💰 4. Investment attractiveness The project belongs to the category of highly profitable renewable energy facilities. At a tariff of 4.42 soms/kWh, the expected annual revenue provides a payback period of 4.5 to 6 years. Advantages: minimal construction risks; simple installation of a single 1400 mm diameter string; reduced capital expenditures on metal structures and supports; scalability (a second string for increased capacity). 🏗️ 5. Conclusion: The cascade option on the Arym River is a technically feasible and economically feasible project, ensuring stable power generation, a rapid return on investment, and long-term operational reliability. The project is ready for further design, approval, and investment.
