- Visible governor control conditions from Control Room Display.
- Easy change of governor properties through the set parameters with sufficient protection to prevent wrong or mis-settings.
- Arbitrarily controllable maximum fuel supply.(Chief Limit).
- Easy checking of governor output conditions from control room display by
- simulation test.
- Constant amount supply control from control room (Fuel mode).
- Fuel Rack control from control room (Direct Mode).
- Stabilized fuel rack with no fluctuation under abnormal conditions that can affect the engine running speed.
- Easier installation owing to downsized motor driven actuator and
- Easier actuator maintenance owing to brushless motor adoption
1. High cost: Manganese bronze is a costly alloy, making it less economical for large propellers. 2. Low strength-to-weight ratio: Compared to other propeller materials like nickel-aluminum bronze or stainless steel, manganese bronze has a lower strength-to-weight ratio. 3. Susceptible to corrosion: Manganese bronze can corrode in seawater, especially when exposed to high velocities and turbulence. 4. Poor cavitation resistance: Manganese bronze is more prone to cavitation damage than other materials. 5. Difficult to cast and machine: Manganese bronze is challenging to cast and machine, making it less desirable for complex propeller geometries. 6. Limited weldability: Manganese bronze has poor weldability, making repairs and modifications difficult. Nickel-aluminum bronze or stainless steel are commonly used for propellers due to their: - High strength and durability - Excellent corrosion resistance - Good cavitation resistance - Ease of casting and machining - Weldability
