cover is made according to the vessel hull lines and is fastened to the bottom well casing

4. STEERING HYDRAULICS 回转液压系统
4.1 GENERAL 综述
The steering hydraulic system performs the steering (azimuthing) of the propulsion unit. 液压系统将实现舵桨的回转功能。
All components of the hydraulic system are ready installed on the thruster and tested at
factory for easy and time-saving installation onboard, except the components mentioned in the delivery list as separate items. 液压系统中的所有部件都在制造厂车间内装配完成并进行过台架试验，这样可以大大简化在船厂安装舵桨时的工序和工作量，除个别说明的部件外，所有的部件都安装在围井上发运。
The steering hydraulic system is complete with necessary pump, motor, valves, filters and cooler. 回转液压系统包括必要的液压马达、阀件、滤器和冷却器
The system is independent of the electric power other than 24 V DC battery – so turning
function is fully operational also during an electric black-out. 该系统除２４伏电源外，不需要任何电源，所以在全船处于失电状态是，该系统仍可完全正常地工作。
The steering hydraulic system has a separate oil tank, and thus is entirely separated from the lubrication system. 回转液压系统还包括有一个独立的油箱，所以该系统与润滑系统是完全分开的，这样可以避免由于润滑系统中进入杂质而使液压回转系统中昂贵的部件受损。
Steering pump主回转泵........variable displacement axial piston pump轴向柱塞式变量泵
Turning control回转控制...........proportional adjuster of the pump通过对泵进行比例调节4.2 STEERING OF THE PROPULSION UNIT舵桨单元的回转
The oil flow, produced by a pump is led directly into the hydraulic motors connected to
steering gear. 由液压主泵产生的液压油直接导入与回转齿轮相连的液压马达内，液压马达转动与中间部件连接的回转环，从而实现推进装置的转动
The steering speed is proportional to the difference between the actual value and the set
value. 根据舵桨机实际的位置和要求位置的差值的大小，控制系统通过电气对主回转泵进行比例调节。
4.3 MAINTENANCE / LOCAL STEERING METHOD维修／应急转舵
? Manual local control on the main hydraulic pump without a tool (in case of electric control system failure). 就地控制，通过舵桨舱内的按钮进行回转控制（需要24 伏电源）
5. LUBRICATION OIL SYSTEM润滑系统
5.1 GENERAL总论
The lubrication oil system performs the following functions: 润滑系统实现以下功能
? Lubrication润滑
? Cooling冷却
? Lubrication oil filtering对润滑油进行过滤
? Clutch operation离合器的控制
? Gravity tank 密封油柜
Lubrication pump润滑泵....................................fixed displacement pump 定量泵
5.2 LUBRICATION润滑
The lubrication of the Ulstein Aquamaster thruster is a self-sustained, built-in arrangement.
舵桨机具有内置自润滑系统（即无动力式润滑），润滑系统与回转液压系统为完全分开的油路。
The lubricated objects are either immersed or sprayed with oil. The oil circulation is arranged with internal boosters. 所有的润滑部位都是通过油浴或喷淋的方式进行润滑的。使油产生循环的动力来自系统内置的增压器。不论是有主机驱动舵桨，还是由于水流带动舵桨旋转，该系统的润滑作用总是充分的。
5.3 COOLING冷却
Lubrication oil is cooled with an external cooler. The cooler is of tube type and is suitable
for either freshwater or seawater use. 润滑油由外置的冷却器进行冷却，冷却器为管式，适用于海水。
5.4 LUBRICATION OIL FILTERING润滑油滤器
For lubrication oil filtering and cooling there is an external pump. 润滑油的过滤和冷却是由机带泵进传行传动的
5.5 CLUTCH OPERATION离合器的控制
The clutch is engaged with lubrication oil pressure and disengaged with springs. The engagement and disconnection is intended to use with idle speed of engine. 离合器的控制是由润滑油压进行啮合，当油压释放后，通过弹簧张力脱开。离合器的啮合或脱开需在主机怠速下进行操作。
The clutch control valve is electrically controlled, but also manual control is available. The valve is designed to maintain its position in the case of loss of control signal. If the hydraulic pressure is lost the clutch disengages but it can be locked manually to ‘engaged’position. 离合器的控制阀是电控式，但也可以通过手动控制。该阀设计为当失去控制信号时，可以保持在原来位置。当液压压力失去时，离合器自动脱开。但是这时也可以通过手动将其保持在啮合位置
5.6 SEAL OIL TANK (GRAVITY TYPE) 密封油柜（重力式）
The oil in the gravity tank line maintains the internal static pressure against water for the propeller shaft and steering tube seal cavities. If any of these seals starts leaking the oil level in the gravity tank drops which indicates the crew that there may be something wrong with the seals. When the oil level in the gravity tank goes below the limit there will be an alarm. 重力油维持螺旋桨轴和回转管密封内的内部静压，使在密封受到损坏时可以立即收到报警信号，以便及时修理。当密封油柜中的油位下降时，将控制系统中将产生报警。
Installation of seal oil tank is taken care by shipyard. 重力油柜的安装和油管的连接由船厂施工。

Aquapilot 控制系统是一种独立的随动控制系统，每台舵桨都带有自己的非随动备
用控制系统。也就是说两台舵桨的控制系统互相不受任何影响。
8.1.2 Bridge control electronics and bridge control and indication devices 驾驶室控制
电路及控制指示设备
The basic operation unit of the system is the Aquapilot control head, which is a single lever for operation of the functions (steering, rpm, pitch) of the thruster. 控制系统的基本操作装置是Aquapilot控制手柄，控制手柄，这是一个单手柄，可对每台舵桨机的回转、转速以及离合器进行控制。

panel(s)。控制系统的选择和指示功能通过控制面板进行。
All indication lights for Ulstein Aquamaster controls are dimmer controlled by push buttons on Ulstein Aquamaster control panel.控制系统的所有的指示灯的亮度都可以通过控制面板上的调光按钮来进行调节。
8.1.3 Steering control 回转控制
Ulstein Aquamaster has a digital follow-up (FU) type Aquapilot control system for controlling the azimuth of the Ulstein Aquamaster unit. The Aquapilot control head provides Ulstein Aquamaster turning (steering) control by horizontal rotation through a continuous 360 degrees.
Aquamaster 配备数字式随动 （FU） 控制系统 Aquapilot ， 水平转动手柄将控制舵桨机在３６０度范围内进行连续的回转，并且在手柄上每９０度的位置都有一个停顿点。
8.1.4 Prime Movers rpm control by Aquapilot 主机的转速控制
PM’s speed is controlled by tilting the Aquapilot lever.
通过扳动Aquapilot 控制手柄，可以对主机进行速度控制。
The rpm set signal to PM’s governor is as standard 4…20 mA.
发到主机调速器的转速控制信号为4…20 mA。
8.1.5 Clutch control 离合器控制
The Aquapilot lever engages the Ulstein Aquamaster clutch by tilting the lever five degrees from the upright position. 通过将控制手柄从直立位置扳动到5度的位置，可以向离合器发出啮合指令。
When returning the lever back to the upright position there is a step for sensing the clutch operation range. This is to avoid inadvertent clutch disengagement.
