boat prop

This propeller is for large work boat 15000 tons, The material is Ni-Al-Bronze which has very good physical properties and corrosion resistance, mostly apply for marine ship propeller. This propeller is 4 blades fixed pitch propeller, K-plan propeller with Nozzle( duct propeller), with the diameter 2.8 meter, and 2.6 tons, polished with popular pattern, high efficiency and saving fuel when sailing.

This propeller is for high speed passenger ship 106 meter, The material is Ni-Al-Bronze which has very good physical properties and corrosion resistance, mostly apply for marine ship propeller. This propeller is 5 blades fixed pitch propeller, with the diameter 1.6meter, and 500 kgs, DAR is up to 0.95, speed is 900rpm, polished with popular pattern, high efficiency and saving fuel when sailing. the sailding speed is up tp 22knots ​

Its optimal propeller diameter-totating speed combination helps to improve the propelleris propulsion efficiency,reduce diameter under the same propulsive force and enhance the tank capacity use rate. The slanted blades and large blade area ratio help to reduce vibration and ensure better cavitation resistance. Submerging these gears and bearing into the lubricant will help to improve lubricating and cooling effects and enhance sideways-acting reliability. The use of optimal design for underwater mechanism allows compact structure and easy installation and maintenance. Its good stern leak tightness is able to meet the increasing strict marine pollution prevention requirement.

It is propeller blades for controllable pitch propeller,, The material is Ni-Al-Bronze which has very good physical properties and corrosion resistance, mostly apply for marine ship propeller. This propeller is 5 blades controllable pitch propeller, with the diameter 4.2meter, and 5.6 tons, polished with popular pattern, high efficiency and saving fuel by adjusting the propeller pitch when sailing. The propeller hub is mainly produced by 5 axis CNC machine, all dimensions must be accurate.
