2全回轉(zhuǎn)對(duì)轉(zhuǎn)槳推進(jìn)器
 2. Azimuth thruster with contra-rotating propellers
 全回轉(zhuǎn)對(duì)轉(zhuǎn)槳推進(jìn)器融合了對(duì)轉(zhuǎn)螺旋槳的結(jié)構(gòu)優(yōu)勢(shì)與全回轉(zhuǎn)舵槳的機(jī)動(dòng)靈活，在提供全方位推力的同時(shí)可有效縮小螺旋槳直徑、提高推進(jìn)效率、減小振動(dòng)和噪聲。主要運(yùn)用于運(yùn)輸船、汽車渡輪、溢油回收船、環(huán)衛(wèi)工程船等有特殊要求或特殊限制的船舶。產(chǎn)品功率范圍60HP-3500HP。
 Azimuth thruster with contra-rotating propellers combine the structure advantages of the contra-rotating propellers and the flexibility of Azimuth thruster. While providing All-directional propulsive force, the diameter of the propellers is shortened, the propulsive efficiency is improved, the vibration and noise is decreased effectively. They are mainly used in ships with special demands or with special limits, such as transportation ships, car ferries, ships for spilt oil recovery, sanitation engineering ships and others. The power range of the products is from 60HP to 3500HP.
