How long is the service life of marine propeller blades generally?
Large engineering ship propeller manufacturer - the service life depends on factors such as seawater salinity and navigation area, but the propeller is very sensitive to external physical factors. NCP series adjustable propeller manufacturer - for example, if an ice block touches the ice once, it will not be useless, and if repaired, it will be half useless sooner or later. Because the pitch changes, it will affect the speed efficiency and cause vibration and abnormal noise.
Large engineering ship propeller manufacturer - The main factors affecting propeller life are navigation conditions in inland rivers, mainly considering the wear and tear of the propeller blades caused by sand and stones. In inland rivers, the main factors considered are salinity, seawater cleanliness, and other impacts. It is really difficult to say the specific life span. Personally, I have been exposed to fast wear and tear in inland sand dredging and transportation ships.
Large engineering ship propeller manufacturers - the mainstream material is copper alloy. The surface material is the same as the internal material, but the difference may be due to surface defects and local welding repair parts being different from the internal material. NCP series adjustable propeller manufacturer - the surface is generally polished smooth and not smooth. When the propeller rotates smoothly, it will cause small eddies in the water flow, increase noise, and cause cavitation corrosion.
