Drain 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 FNIS :
- No-load engine startup during declutching
- Simple operation via the solenoid valve
- Absorbs shocks and dampens vibrations
- Enables smooth machine startup
- Prevents belt slippage
- Robust and low-maintenance
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
