USHMILO STANDARDIZED VERTICAL SUBMERGIBLE WATER TURBINES
The unique long-life power generators from falling water

Standardized, innovative designs covering a wide range of heads and flows to permit economical development of the many sites, or where more modern generating units can economically increase the amount of power generated efficiently. Modern, more efficient and trouble-free, Ushamil programme covers all types of standardized turbines as well as gates and Self-cleaning Static Intake Screens Auto Load Control & Governing Systems.

Low head sites can be built fast at lower cost. The powerhouse structure can be very substantially reduced in area and height and in most cases
eliminated.

Ushmilo vertical turbines occupy less space with a considerably higher capacity. · To reduce operating costs these power plants are often equipped for automatic or remote control operation. · The plant’s associated auxiliary equipment is also simplified. · Because of high efficiency and flexibility Ushmilo vertical turbines allow effective use of each model in a range of water-flow regimes, which can be easily used in multiple combination depending upon water-energy available, to optimise generating capacity at each site - even where water flows vary greatly due to seasonal changes or other reasons. This further enhances the cost-effective use of capital equipment.

• EFFECT OF SILT and FLOATING BODIES : The conventional turbines have adjustable guide-blades manually controlled in small turbines or mechanically in larger turbines through governors. This is a great weakness of such conventional machines since the silt and floating bodies in the water usually clog the small passages through the guide-vanes. Due to corrosion and silt moving portion of the vanes wear out and therefore need replacement quite frequently resulting in stoppages for long periods.

• The modern concept is to use fixed vane type machines having no moving parts except the impeller. The water flow is maintained constant in the turbine and the load variation is taken over by transferring the unutilised energy to be dissipated in the Auto Load Control & Governing System.

• A small hydropower station has to operate unattended in order to be profitable. The Ushmilo Control Center achieves this by automatically starting, regulating and stopping the turbines. Both Grid-connected or Stand-alone units are available

• The power set starts automatically to reach the rated frequency of 50 Hertz. All protective relays will disconnect the generator circuit breaker and stop the turbine in case of any emergency. · Besides automatic operation, also manual operation is possible for both modes of operation, whereby all manipulations and adjustments are performed by the operator manually by pressing the buttons of the Control- device.

UNIQUE FEATURES OF SUBMERGIBLE USHMILO VERTICAL TURBINES

No Turbine - houses generally required - may be easily installed in the open, being of Submergible design. · Much reduced project - cost. · Very little erection time - · The control panel may be put in a convenient remote location. · Compact simple design with close - coupled submergible generators - needing very little space. Heads may be as low as 5-meters. · No belts, pulleys or flexible couplings - No alignment problem. No mechanical governors. · Designed for water with silt. · Easy minimal maintenance - long trouble free life - durable and highly reliable. · Low overall capital cost. · Operating cost - negligible.

Ushmilo vertical turbine units are ideal for : Additions to existing power stations. · Recovering the last ‘ounce’ of energy being lost in freely falling water from existing hydel stations. · Replacement of old horizontal obsolete units. · Resorts, hotels, camps and hospital facilities etc. · Homes, schools, community projects, isolated villages.
