Large container propellers - The failure of ship propellers is a common occurrence

Large container propellers - During operation, if the air pockets are near the surface of the propeller, the blade material will corrode due to long-term and sustained hydraulic impact, resulting in pitting corrosion.

Large container propellers - Cavitation often produces vibration and noise, and spot corrosion can occur on metal surfaces. In severe cases, dead blade perforations or ruptures can occur. Large container propellers cause instability in the center of gravity of the entire propeller, resulting in vibration and noise. The methods to solve these problems are as follows:

Large container propeller - Improve the design of the blade structure, increase the flow area, reduce the thickness of the blades, and make the shape of the blades streamlined.

Air conditioner large bulk propeller - increase the inlet angle of the blade, reduce blade bending, and thus reduce blade blockage.

Air conditioner large bulk propeller - replace the blade material with anti cavitation materials. For example, air conditioner large bulk propellers should be made of materials with high hardness, strength, and toughness, and have good chemical stability.

The failure of ship propellers is a common occurrence, and the reasons for the failure of air conditioning large bulk propellers made of different materials on different ships cannot be analyzed on an equal footing due to differences in their working conditions.

Air conditioning large bulk propeller - When dealing with faults and analyzing them, the actual water surface conditions and the working conditions of the surrounding components of the air conditioning large bulk propeller are taken into account to avoid relying on experience to determine the cause of the fault.
