Precision Control for Hydro Turbines
Hydro Mechanical Control Panel is an advanced hydraulic control system designed for precise and reliable regulation of Guide Vane, Nozzle, Deflector and Runner Blade in hydro turbines. The HMC integrates servo proportional valve technology to ensure smooth, efficient, and safe hydro turbine operation.
Key Features :-
- Servo Proportional Valve Controlled: High-precision, closed-loop control system with integrated electronics and feedback sensors.
- Dual MDV Control: Independent control of guide vane and runner blade via MDV (Main Distributing Valve).
- Comprehensive Front Panel Interface: Equipped with digital meters, position indicators, selector switches, emergency push buttons, and illuminated indicators for local and remote operation.
- Built-in Safety: Includes emergency closing solenoid valves, shuttle valves, pressure switches, and lockout mechanisms.
- Robust Construction: Heavy-duty, gasketed steel cabinet with louvers, internal lighting, door switches, and oil-resistant sealing.
System Components
- Manifold Assemblies: Includes servo valves, solenoid valves, pilot-operated valves, shuttle valves, and test points.
- Piping & Fittings: SS 304 seamless pressure and drain lines with standard flanges and fittings, hydro-tested for durability.
- Instrumentation:
- Servo Proportional Valves (4-20 mA, IP65)
- MLDT ( Magnetostrictive Linear Displacement Transducer) for real-time feedback
- Digital indicators (GV, RB position, MW, Tachometer)
- Pressure gauges, transmitters, and switches
- Safety & Interlocks: Emergency push buttons, interposing relays, auxiliary relays, mechanical and electrical protections.
