Leak off Nozzle Type Fluid Coupling
Overview :
- Radially Displaceable fluid couplings with resilient driving plate on.
- Input side and metallic disc flexible coupling on output side.
Applications:
- Ideal for startup and acceleration in Belt and Pipe Conveyor systems, underground mines, surface installations, crushers, mills, and more
Operations:
- Oil circulates through the working circuit
- Leak-off nozzle drains oil into the secondary casing
- Solenoid valves adjust oil levels between 0% to 100%
- Declutching empties the circuit via solenoid valves
- Electronic control adjusts oil levels during acceleration
Types of FNCT
- Controlled startup and smooth acceleration for large drive motors
- No-load motor startup reduces starting current
- Wear-free power transmission
- Gradual breakaway torque
- Clutching and declutching with the motor running
- Dampening of shocks and vibrations
- Suitable for electronic control and multi-drives
- Cooling during standstill
- Compatible with various couplings
- Robust, low maintenance design
Construction:
- Primary casing houses Impeller and Rotor
- Fixed Scoop Tube collects oil from the working circuit
- Shafts connect Impeller and Rotor to motor and driven machine shafts
- Bearings support the shafts
- Robust, self-supported housing
- Motor-driven oil pump circulates working oil
- Solenoid valves and non-return valves control oil levels
- Lube line feeds oil to bearings continuously
