The NRP250 fixed pitch rudder propeller was awarded municipal prize
Recently, Nanjing municipal government announced the decision of honoring the 2013 awarded enterprises and individuals with Nanjing Science and Technology Progress Prizes, and the NRP250 fixed pitch rudder propeller made by Nanjing High Accurate Marine Equipment Co., Ltd. was awarded the third progress prize. This product also has been selected as Jiangsu High and New Tech Product, the First Set of Important Equipment in Jiangsu and was awarded the Jiangsu Excellent New Product Golden Prize in 2013.
The NRP250 fixed pitch rudder propeller made for the Xiangyanghong No.10 scientific research vessel
Some hydrodynamic theoretical methods like lifting line, lifting surface, CFD etc. were utilized to optimize the design of NRP250 fixed pitch rudder propeller. It improves the accuracy and efficiency, restrains the vibration and cavitation, and meanwhile improves the propulsion efficiency of the propeller. The rudder angle feedback, the manual swinging gear, the oil drainage tool and hydraulic system are modular designs, which make them easy to be replaced and maintained. 7 national utility models patents have be granted for this product, and the product quality has reached the European standard. It is featured with reliability, smart and easy maintenance.
Nanjing High Accurate Marine Company has been focusing on technology and continuing innovation, and has provided the customers with outstanding products. The company can provide each kind of transmission and propulsion equipment except prime mover, including controllable pitch propeller, fixed pitch propeller, azimuth thruster, tunnel thruster, main or auxiliary gearbox for all kinds of ships, shafting and steering components and deck machinery, etc. The rudder propeller products can be widely used in ocean liftboats, harbor tugs, crane ship, cable ship, scientific research vessel and all kinds of military vessels. Development on rudder propellers ranging from 500HP to 5000HP has been fully completed. Over 100 sets of product are running in real ships, and have been praised by customers.
