In this system, the degassing/mixing tank operates as a fuel buffer, ensuring gradual changes of viscosity which results in a stable control of the viscosity. The ViscoSense.2 sensor is used to measure the actual viscosity of the fuel oil. The signal from the sensor is compared to the setpoint of a viscosity controller, which regulates the output of the fuel heater via a control element (steam or thermal oil valve, or electric heater cabinet). Figure 1 Typical example of an automatic control system using steam or thermal oil heater 图表1给出了一个典型的具有主机回流管路的燃油处理系统图。在该系统中，除去瓦斯/混油桶起到燃料缓冲器的作用以确保黏度渐变，从而获得对黏度的稳定控制。控制系统对黏度传感器发出的信号与控制器的设定值进行比较，通过控制元件[蒸汽，热油阀或电热器]以调节加热器的输出 Marine Diesel Oil 船用柴油Heavy Fuel Oil 重燃油Feeder Pump 供给泵Degassing/Mixing Tank 除去瓦斯/混油桶Filter 过滤器Booster Pump 增压推进泵Fuel Heater 燃油加热器Steam/Oil 蒸汽/油Control Element 控制元件Controller 黏度控制器ViscoSense.

Interface box 界面盒 The sensor housing is made of ductile iron and has flanges for direct mounting in the fuel line. The sensor itself is made of stainless steel and is mounted in the housing. The sensor head has a special Teflon. coating and it is mechanically protected by a stainless steel flowtube with 3 oval slits. It is supplied with 5 metres of signal cable for connection to the interface box. The ViscoSense.2 Interface box is a wall mount electronic unit, processing the signals from and to the sensor. It provides 4..20 mA signals for remote read-out of viscosity and temperature for a controller or other system elements.

Two sets of piezo-electric elements (4) are positioned inside the pendulum. One set drives the pendulum, the other set measures and controls the rotational movement of the pendulum via a feedback circuit. In this way the pendulum is kept in vibration at its resonance frequency. 传感器系由通过扭管(3)固定在基座(2)上的钟摆(1)组成。钟摆内置两套压电陶瓷元件(4)。一套驱动钟 摆，而另一套通过反馈信号测量和控制钟摆的旋转动作。这样使钟摆在其共振频率上保持振动。 Measuring the resulting frequency at two specific values of phase difference, yields a value for the damping which is proportional to the square root of the dynamic viscosity. 测量相位差两点的频率，得出衰减值。这一数值与动力黏度的平方根成正比。 A flow tube (5) is placed around the pendulum, to protect it against mechanical damage. 流管(5)被置于钟摆外围，以保护钟摆避免机械损坏。The flowtube is machined with a smooth surface, as well as with a triplet of oval slits. These slits increase the refreshing rate between sensor and flowtube. 流管经过精细机加工处理，表面光滑并有三个椭圆形开口。这些开口增加了传感器探头和流管之间的更新速率。 Figure 3 ViscoSense.2 sensor 图3 扭转振动传感器探头 3 TECHNICAL SPECIFICATION 技术规格 3.1 SENSOR 传感器 Viscosity range 粘度量程0 .. 25/50 mPa.s 毫米帕斯卡·秒 (other ranges on request 其它粘度量程根据要求而定) Maximum operating temperature 180.C 最高温度180.C Temperature transmitter PT 100 element 温度传感器PT100 铂电阻温度传感器元件Accuracy 精度 Viscosity 黏度+/- 2% instantaneous 瞬时误差±2% 或 0.5 mPa.s Temperature 温度 ± 1.C 约1 摄氏度Measuring range 温度量程 0-200.C 0-200 摄氏度Material 材质 Sensor 探头 Stainless steel 316L 不锈钢 Coating 涂层 Teflon. 特富龙.

When fuel viscosity is 500 mPa·s or thicker it is recommended to wrap steam tracing with sufficient capacity, or 20 Watts/metre resistance wiring around the ViscoSense.2 housing. 当燃油黏度等于或大于500 毫米帕斯卡·秒时，建议充分包裹蒸汽源及传感器仓室 . VAF ViscoSense.2 sensor and interface box are precision instruments. Handle them with care. VAF扭转振动传感器及界面盒属精密仪器，应小心轻放！ Do not unscrew the cable gland on the top of the ViscoSense.2 sensor or disconnect the cable from the sensor. This will violate the correct operation of the ViscoSense.2 sensor. 勿拧开探头顶端电缆或从探头断开电缆。这将严重违反正确的操作规程。 Take care that the pendulum is not damaged and the torsion tube not bent by mechanical force. This will violate the ViscoSense.2 signal. 小心轻放，特别注意钟摆和扭管免受损伤以及机械力而弯曲。否则，这会影响传感器信 号。 6.4 MECHANICAL INSTALLATION 机械安装 6.4.1 ViscoSense.2 interface box 传感器界面盒 1. Install the ViscoSense.2 interface box in a suitable location, free from excessive vibrations, humidity and excessive temperature variations. 界面盒应安放在适合的地方，避免过渡振动以及温湿度变化。 2. The maximum distance between sensor and the interface box is determined by the cable length from the sensor, being approx. 5 metres. 传感器与界面盒之间的距离是由传感器电缆长度决定的，大约5米。 3. Allow sufficient space for installation of cables and for servicing. 留有充分空间以便安装电缆和服务需要。 6.4.2 ViscoSense.2 housing 传感器安放室 1. Remove dust caps from sensor housing and install housing stress-free, with shutoff valves and bypass valve in the fuel piping as illustrated in Figure 6. Take care that the flow direction is in accordance with the indication on the housing (inlet, outlet and arrow) as illustrated in figure 8. Support inlet and outlet piping sufficiently. 除去防尘盖，根据图6所示，安装仓室，止阀及辅助阀门。按图8所示，根据仓室表面指示，注意流动方向(入口，出口及箭头)，充分固定入出口管路。 These shutoff valves and bypass valve are not furnished by VAF Instruments.这里的止阀及旁通阀非VAF提供。 2. Note that the distance between fuel heater and sensor housing inlet should not exceed 4 metres. 注意：燃油加热器与探头安放仓室入口间的距离不应超过4米。 3. To protect the instrument from excessive vibrations, which can cause malfunctioning of the instrument, it is recommended to: 为防止仪器因过渡振动引起的误操作，建议： Install the ViscoSense.2 as low as possible in the fuel system close to a solid structure or beam. 在燃油系统中尽可能低的安装传感器，并靠近稳固结构或梁。 Install suitable pipe clamps at both sides of the ViscoSense.2 sensor. 在传感器两侧安装适当的管夹。 4. Allow at least 50 cm clearance to the sensor housing, to be able to take out the measuring sensor for service. 5. The sensor needs a stable environment to act as a counterweight for the pendulum movement. The support must prevent movement and excessive vibrations of the ViscoSense.2 housing, especially movement in the direction of the pendulum movement (see drawing- angular movement around the sensor axis). Therefore there must be two supports to the inlet and outlet perpendicular to the pipe and perpendicular to the ViscoSense.2. If one support would be used the lateral vibrations would be converted to angular vibrations and the situation would be made worse instead of better. 预留至少50公分距离，以便于维修服务时取出探头。传感器需要一个稳定的工作环境，以保持钟摆运动的平衡。支撑固定架必须起到防止探头仓室移动及过渡振动的作用，尤其是防止其在钟摆运动方向上运动(参看图纸-钟摆环绕传感器轴线的角度运动)。因此必须有两个固定支撑架，分别位于入口和出口，且与管路及传感器垂直。若仅使用一个支撑，那么横向振动既会转换为角振动，系统情况将变得异常糟糕。 Figure 6 Sensor installation diagram 图6 探头安装图示 The angular position of the supports must always be 90° in relation to the sensor.固定架与探头之间的角度必须90o。The distance from the flange to the support should be two times the diameter of the pipe. 法兰与固定架之间的距离应为管路直径的两倍。 ViscoSense.2 size 探头仓室连接法兰尺寸 T.

Remove transport locking cap from bottom side of flowtube. 从流管底部拆除运输中防止残损的锁定鞘 3. Please make sure not to damage the Teflon. coating during installation. 安装中杜绝损伤特氟龙涂层。 Without the transport locking cap the sensor is not protected against excessive mechanical shocks which can occur during handling. 注意：没有锁定鞘，既无法保证探头在运输，装卸过程中可能受到的过度的机械振动冲击影响。 4. Install sensor carefully in housing with the closed surface facing the flow, illustrated in figure 8. 小心地将探头置于安放仓室内，注意流管的封闭面朝向流动方向，参见图8 。 Make sure the flow tube closed surface is pointing towards the inlet of the sensor housing, see figure 8. The sensor will not work correctly if installed wrongly. 确保流管封闭面朝向探头安放仓室入口。不正确的安装会导致传感器无法正常工作。 Check if the position of the hole inside the housing and the fixation pin on the sensor match. 检查探头上用于固定的插头与安放室内的孔眼是否对位。 5. Tighten the nut (1) by hand. If there is a temperature difference between the sensor and the housing you should wait until they have the same temperature before tightening the nut. 首先用手固定螺帽(1) 。在紧固前若探头与仓室间有温差，则应等待直到两者温度相同为止。 6. Tighten the nut (1) with a wrench with a recommended torque of 100 Nm. 然后用螺旋钳在100牛顿米的扭转力矩下上紧螺帽(1) Make sure that all flange bolts and nuts are tightened correctly before re-pressurizing the system. 确保所有连接法兰之螺钉螺帽在重新施压前已充分紧固。 See chapter 15.1 参见章节15.1 7.

Failures and errors are displayed by a blinking digit or character on a 7 segment LED. Dependent on the type of failure, error or warning, the viscosity and/or temperature outputs will go to 0, 4 or 20 mA, or will remain functioning normally. 控制器中的印刷电路板有一个实用的帮助分析诊断失效的规定。 误差和故障通过闪光的数字或者符号在一个7片段发光二极管上显示出来。取决于失效，误差或警报的形式，粘度和/或温度的输出将会为0，4 或 20mA; 或者保持正常功能。 If there is no failure, error or warning, the display indicates the state of the program by displaying a symbol (not blinking) on the display. 如果一切正常，显示器上将会显示指示程序状态的（不闪光跳动）符号。The following symbols are displayed during normal operation: 正常操作情形下，将会显示下列符号： Power on 电源接通 Changing U-send_setpoint 改变电压输出信号设定值 Initializing hardware 硬件初始化 measuring at + 45 degrees (left -3 dB point) 在相位+45 度时测量(左-3 dB点) VCO frequency measurement while phase is +45 degrees 压控振荡器在相位+45 度时频率测量 measuring at - 45 degrees (left +3 dB point) 在相位-45度时测量(左+3 dB 点) Waiting for U_receive to settle after changing setpoint 改变设定值后等待电压信号 Adjusting phase 正在调节相位 The decimal point at the bottom of the display is always on after power is on. This point is only turned off while the ViscoSense. is writing to EEPROM, and if no measurement is possible due to extensive external vibrations. 电源接通后小数点总是在底部显示。如果由于巨大的外部振动导致无法测量，传感器写入电可擦只读存储器时它才消失。 Normally the ViscoSense.2 electronics will try to restart the unit if a faulty situation occurs. However, if the fault is persistent contact VAF Instruments or your local authorised VAF dealer and give a detailed description of the problem that occurred and the diagnostic information indicated at the 7 segment LED. 通常如果发生故障，传感器将会重新启动装置。但是如果故障仍然存在，请及时与VAF或所在地经VAF授权的销售商联系并提供详尽的问题情况说明以及在7片段发光二极管上显示的帮助诊断资料。 The faults, indicated in the table below, are listed in order of priority. The faults on top of the list have the highest priority. This means that faults with a lower priority can be overwritten by faults of a higher priority. At power-on the system is explicitly tested for failures indicated by display messages 1, 2, 3, 4, 5, 6 and 7. During normal operation these tests (except 2) run at the background. 下表中指出的故障系按优先顺序排列。表中上方的故障有最高优先权。这意味着拥有高优先的故障可以覆盖低优先问题。当接通电源后，系统将明确地检测是否存在故障，此时显示器依次显示信息1, 2, 3, 4, 5, 6和7。在正常操作情况下，这些测试（2 除外）将在本底进行。 Followed by 接下来: or or Display message 显示信息 Viscosity output [mA] 黏度输出 Temperature output [mA] 温度输出 Recovery action (attempt) 恢复动作(尝试) Fault description 故障描述 0 0 Delay & retry 15 V power failure.

A larger inner diameter will give a slower fuel velocity. 燃油的速度取决于循环/增压推进泵的容量以及所用管路之内径。内径越大，流速则越慢。 .The recommended fuel velocity in the booster unit is 1 - 2 m/sec 单元中的燃油推荐流速为1-2 米/秒.The recommended fuel velocity to and from the engines is 0,25 – 0,5 m/sec 进出发动机的燃油流速建议为0.25-0.5 米/秒 Remarks 备注: .A too high fuel velocity will result in larger pressure losses within the booster unit. 油速过高会导致供油单元系统中较大的压力损失 . A too high fuel velocity can result in unstable viscosity measurements. 油速过高会导致粘度测量不稳定 . A too low fuel velocity will result in a slow and possibly unstable viscosity control 油速过低会导致粘度控制迟缓及不稳定 VAF Instruments delivers the ViscoSense.2 with housing. Refer to the table below for flow rate corresponding to the size of housing: VAF 提供之ViscoSense.2 具有专门的探头安放仓室。参见下表以获得与仓室尺寸相对应之流速： Fluid flow rate in piping 管路中的流速All at 0-50 mPa.s 黏度均在0-50mPa.s范围内(Recommended for correct control function) 2” - Max 20 m3/h, Min 7m3/h （为实现正确的控制功能而推荐）2.5” - Max 34 m3/h, Min 12m3/h 3” - Max 51 m3/h, Min 18m3/h 4” - Max 80 m3/h, Min 28m3/h For lower flow rates a smaller pipe diameter is recommended. 对较低流速建议采用更小尺寸的管路 Mixing tank 混油桶The mixing tank is an important part of the booster system that has several functions. 混油桶系供油单元中的一个重要部件。它具有如下几项功能。 .The mixing of MDO and HFO to a homogeneous emulsion. 混合重油及柴油达到均质状态.The mixing of hot ( +/- 130° C ) with colder (+/- 80 °C ) fuel, to a fuel with a single temperature 充分混合热油（±130° C）及低温油（±80°C）达到具有单一温度的燃油.Compensation of pressure pulses 弥补压力波动.Prevention of a thermal shock of the engine when changing over from HFO to MDO. 防止系 统在重油转换至柴油时产生热冲击 Remarks 备注 .If hot and cold HFO is not mixed well, it can result in incorrect viscosity measurements, which will result in an incorrect viscosity control of the system 如果冷热油未充分混合，会导致粘度测定不准。这样将会引起系统粘度控制的误动作。 . High or constant pressure pulses in the system can lead to damage to the ViscoSense.2 or other components of the booster unit. 系统中压力波动较大并持续时，会导致ViscoSense.2 传感器和/或单元中其它部件的损坏。 Fuel filters 过滤器There should be two fuel filters, placed parallel. One should be clean and on standby. 系统中应当采用两个并行放置之滤器。其中一台应当清洁并调整妥当备用。Fuel filters should be placed in the HFO supply to the booster. 过滤器应安装于重油供油管路增压推进泵前 .The fuel flow is less; therefore the filter can be smaller. 燃油流速较低时可选用更小的过滤器.The fuel temperature is lower and the fuel is more stable. 燃油温度越低，越稳定。Heaters 加热器Heaters can be steam, or electric. 加热器可以是蒸汽式的，或者是电子式的。There must be two heaters placed parallel in the system. Only one heater should be switched on. The other one should be clean and on standby. 系统中必须有两套加热器。一套启动工作，而另一套应清洁妥当以待命 Booster pump 增压推进泵There should be two booster pumps. 系统中应当拥有两套增压推进泵。One active and the other one on standby 一套处于工作状态；而另一套处于待命状态。
