KONGSBERG MARITIME AZIMUTH THRUSTERSAzipullKongsberg Maritime azimuth thruster (Azipull)Is a low drag, high efficient pulling thruster. It combines the advantageof the pulling propeller with the flexibility of using almost any type ofdrive to suit the customer’s specific requirement. The Azipull is designedfor continuous service speed at 24 knots, while maintaining excellentmanoeuvrability.High hydrodynamic efficiency, fuel efficiency, course stability, low noiseand vibration levels are other key characteristics of the Azipull.Internally, it has a purely mechanical drive system based on well-proventechnology using bevel gears at the top and bottom of the leg. Power is fedto the unit through a horizontal input shaft within the hull, and the unitincorporates its own steering motors for azimuthing.The Azipull combines the advantages of an azimuthing thruster offeringhigh manoeuvrability, and low drag high efficient propulsor enabling highspeeds. The flexibility of the unit is also enhanced by the fact that it isavailable in both CP and FP. The Azipull is delivered with remote controlsystems.06.Azimuth-1 of 2-11.06.19The main characteristics are:• Low drag, high efficiency pulling azimuth thruster • High hydrodynamic and total efficiency • Low noise and vibration levels • Course stability • Continuous service speed of 24 knots while maintaining good manoeuvrability • Can be linked to any kind of prime mover, accepting diesel or gas turbine with mechanical or electrical drive • Flexible with respect to vessel application, enhanced by availability in CP and FP versions Within the hull of the vessel is the upper gear housing, steering gear and auxiliaries, and these are from the standardised Kongsberg Maritime azimuth thruster range to maximise commonality of spare parts and minimise technical risk.The flow of water to a pullingpropeller is only determined by the hull, and it is possible to obtain a more homogeneousinflow to the propeller in this type of thruster. More uniform inflow is decisive for reducingunsteady cavitation, and thereby cutting down propeller inducednoise and vibration and reducingoscillations in shaft torque.The mechanical elements areenclosed in a hydrodynamicallyoptimised leg with a wide chordto provide rudder effect andimprove the vessel´s coursestability. The leg incorporatesa skeg extending below the gearhousing.The streamlined leg and skegrecover swirl energy from theslipstream of the pullingpropeller, raising the overallpropulsive efficiency becausethis otherwise wasted energy isconverted to a forward force onthe thruster leg.TECHNICAL DATA AZP 85CATAMARAN AZP 85STANDARD AZP 100STANDARD AZP 120STANDARD AZP 150STANDARD Prop diameter (mm)1900-2 3001900-2 3002300-2 8002800-3 3003300-4200Power (max cont. rating)17001700250035005000Nominal input speed (RPM)720-1 800720-1 800720-1 800720-1 200600-1000Dry weight (kg)1400020000260004400085000Switchboard: +47 815 73 700Global support 24/7: +47 33 03 24 07E-mailsales:*********************.comE-mailsupport:************************Kongsberg Maritime P.O.Box 483, NO-3601Kongsberg, Norway 06.Azimuth-2 of 2-11.06.19Power is (max cont. rating) if depending on final propeller speed.All models of Azipull can be supplied with CP or FP propeller (FP propeller can be supplied as monoblock or built on blades).All data is subject to change without prior notice.。

舰船常用推进器简介
舰船常用推进器简介普通螺旋桨推进器：结构简单，在低速下效率一般还是较高。
普通螺旋桨推进的能量损失：（1）产生轴向诱导速度的损失。
在螺旋桨作为推进器来工作时，这种损失是不能完全避免的，但可用适当措施使这种损失尽可能减小。
一般，这种损失值将随螺旋桨载荷系数的增大而增大。
（2）产生周向诱导速度的损失，或称为水流扭转损失，其损失值也将随螺旋桨载荷系数增大而增大。
（3）运转时桨叶与水的粘性摩擦作用而产生的损失，或称为剖面阻力损失。
螺旋桨的诱导损失和剖面阻力损失这两项约共耗螺旋桨35%~60%的功率，也就是说，螺旋桨一般从主机取得的功率中用于退出按的功率大约仅占40%~65%。
（4）螺旋桨与航体相互作用，即螺旋桨的附体阻力损失。
减小能量损失的措施：（1）为减小诱导损失，可采用直径更大的螺旋桨，但会增加剖面阻力损失。
（2）为了减小水流扭转损失，可采用特殊的导流设备，例如：反应舵，舵推力鳍以及流线型舵等，减小尾流旋转，回收尾流能量，达到提高推进效率的目的。
（3）为了减小剖面阻力损失，必须注意桨叶剖面形状的选择，在理论设计中，合理选取桨叶宽度，叶厚比及剖面形状，可使剖面阻力损失达到最小（4）螺旋桨与船体及附体的合理配合，不仅能减小推力减额分数和更有效的利用伴流能量，并且也能改进螺旋桨本身的效率。
导管螺旋桨导管螺旋桨也称套筒螺旋桨，它是在螺旋桨的外围加上啊一个环形的套筒构成的。
分为加速型导管（收缩管）和减速型导管（扩张管）。
优点：（1）对于螺旋桨载荷较大的船舶，可获得较高的效率。
（2）在海上航行时，导管桨受外界海况变化影响较小，导管螺旋桨比飞导管螺旋桨的效率降低要少。
（3）导管对螺旋桨有保护作用。
（4）导管能使航向稳定性得到显著改善。
（5）当采用“转动导管”时，导管可代替舵，主要用于小船。
缺点（1）倒车时操纵性差。
（2）在浅水区域航行时，易将碎石、杂物吸入导管；在冰区航行时，易遭破坏。
（3）导管内压力降低，易发生空泡现象，引起导管桨剥蚀。

The user is alerted to a service requestby a simple flashing LED sequence on the pumps and by serial commsnotification.Flexibility is again key as these simple services can be performed either by theend user, on site by an Edwards Field Service Technician, or the pump can bereturned to an Edwards service hub.Using remote diagnostics, a user can interrogate the pump to determine howlong it is to the next service so that a proactive approach to preventativemaintenance can be planned.Technical data* a smaller backing pump may be used depending on application.Performance CurvesDimensionsControllers and accessoriesThe TIC (Turbo and Instrument Controller) automatically recognises and supports one turbo-molecular pump from the nEXT range, plus three Edwards active gauges. Cooling and vent valve support is provided directly from the controller. Backing pump power is provided for a compact 24V diaphragm pump (on 200W versions only), or where greater pumping speeds are required, mains backing pumps (up to RV12) may be controlled via an optional relay box.nXDS and large XDS pumps can be controlled directly via the backing pump connector on a TIC 200. The relay box can also be used to control a mains heater band and backing line isolation valve. Time delays and normal speed signals may be used to control events such as turbo start and there is a comprehensive selection of protection and safety interlock features. The TIC turbo controller may be either rack or bench mounted and provides a useful hub for the flexible operation of a widerange of vacuum system configurations.The TAG (Turbo and Active Gauge) controller is a small, compact, low cost pumping system controller, which is suitable for a wide range of vacuum applications. It is a 24V controller that is compatible with all Edwards DX and nEXT turbomolecular pumps. It contains no power source and therefore you either need to supply your own power or buy the optional power supply. In addition to a turbomolecular pump it can control a backing pump, a vent valve, an air cooler and an Edwards active gauge. The TAG Controller is controlled by an easy to use interface. A large clear LED display shows the pump speed or vacuum pressure.

The Port Control operates on the “meter-out” principle and features an adjustable needle in a cartridge with a check seal. The self-locking needle has micrometer threads and is adjustable under pressure. The needle determines the orifice size which controls the exhaust flow rate of the actuator. The check seal expands while air is exhausting from the actuator, forcing the air to exhaust past the adjustable needle. The check seal collapses to allow a free flow of incoming air. The PHD Port Control saves space and eliminates the cost of fittings and installation for external flow control valves. Refer to option code to specify port control locations.All dimensions are reference only unless specifically toleranced.PORT CONTROLS ® ON BOTH ENDS(Standard location 1 & 5)PORT CONTROLS ® ON EXTEND ONLY(Standard location 1)PORT CONTROLS ® ON RETRACT ONLY(Standard location 5)NOTE: * D imensions shown are for units with port and port control in the same location. For units with other port and port control combinations, standard portlocation dimensions apply.

螺旋桨推进器使用说明书
一、概述
QY-LT系列螺旋桨推进器是制浆造纸工业中浆料循环搅拌最为理想的设备之一，它适用于浆料浓度在5%以下，15~100m3方形浆池，具有占地面积小，混合时间快，搅拌效果好、维修方便等优点，与旧式的搅拌设备相比，具有浆池建造简单，施工方便，装浆量多，单位循环率高等优点。
QY-LT系列推进器由叶轮，锥型支架、主轴、联接框架、轴承，等组成，采用三角带传动，尾端采用一个调心滚动轴承，前端采用聚四氟乙烯塑料轴承，注入压力水润滑。
本设备设计合理，维修方便，搅拌效率比老式搅拌提高20-30%以上。
四、设备的安装：
1、设备开箱吊装时不可捆吊主轴，以免损坏。
2、设备可分部安装。
首先卸下叶轮，再拆下联结框架，轴承支架，使锥型架与框架分离（能保证不影响灌注混凝土质量，也可不拆卸）。
3、将连接框架加强津上的调整螺钉紧预留孔壁，校准中心至池最低的高度，并保证端面垂直度，然后浇灌混凝土与框架，结合面不渗漏为准。
4、固定电机，使电机轴线与推进器轴线平行，两三角带轮槽对正。
五、操作与维护
1、调整三角带松紧合适，检查安装质量；
2、接通润滑冷却水，点起动机看转向是否与要求一致；
3、试运转24小时，检查运转是否正常，轴承是否过热等，发现问题及时处理；
4、正式工作时一定不要断冷却水，润滑清水（水压必须超过轴承水平位置所受到的池内液压）；
5、盘根松紧适度，并注意定期填加或更换，以保证良好的密封；
6、滚动轴承座位填充1/2以上润滑脂，可采用ZFG复合钙润滑脂；
7、每半年加注润滑脂一次，每一年清洗轴承一次，并更换新的润滑脂；
