- Shut steam and water cocks than open the drain cock.
- After draining water from the sight glass, there is nothing come out, both steam and water cocks are good in condition.
- Open the steam cock side, blow out the steam.
- Close the steam cock side, the steam connection is clear.
- Open the water cock side, blow out the water.
- Close the water cock side, the water connection is clear.
- Close the drain cock.
- Open the water cock, water should then gradually come rise up to the top of the gauge glass.
- Open the steam cock, the water in the glass should fall to the level of the water in the boiler.
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
