DISCHARGEMONITORINGEQUIPMENTOilDischargeMonitoringEquipment排油监控装置用于监控含油压载舱水或其它油污水排入海中的系统，监控系统主要由排放监控单元、取样分析单元和舷外排放单元等组成。当含油压载舱水或其它油污水排入海中时，排放监控单元通过取样分析单元来监控瞬时含油量，并且根据船舶航行的速度来指挥舷外排放单元是否将油污水排出舷外或返回到船舶的污油水舱。可对所有向舷外排放的数据进行记录。TheOilDischargeMonitoringEquipmentisusedtomonitortheoilywaterofdischargingfromballasttankorotherpollutionwaterintothesea.Thesystemconstitutebythedischargemonitoringunit,samplinganalysisunit,dischargeremotecontrolunitetc.Whentheballasttankorotherofoilywaterdischargetosea.Thedischargemonitoringunitwillmonitoringinstantaneousoilcontentbysamplinganalysisunitandaccordingtotheshipspeedtocommandthedischargeremotecontrolunitwillletoutoilywaterorreturntothesloptank.Alldischargedatahavemonitoringrecord.OilDischargeMonitoringEquipment计算机控制单元ComputerControlUnit信号采集单元SignalPickupUnits采样泵控制单元Samplingpumpcontrolunit油份浓度测量单元OilContentMeasureUnits流量计探测器Flowmeterdetector取样头SamplingProbe取样泵SamplingPump冲洗水CleaningWater机舱EngineRoom泵舱PumpRoom非危险区NonHazardousArea危险区HazardousArea去污油水舱ToSloptank排舷外OverboardDischarge计程仪SpeedLogGPS信号GPSSignal排放阀控制单元DischargeValveControlUnit流量测量单元FlowMeasureUnitsRD-ODME排油监控系统的组成及布置RD-ODMEOilDischargeSystemconstituteandlayout含油污水经过管道，取样泵开始取样计算机将信号进行处理后，发出指令到信号采集单元，若采样不合格，将仍保持回流阀常开；若采样合格，就将排放阀打开油份浓度测量流量测量单元测量将采集的信号传输给计算机，同时将收到的信号传输给控制单元将计算机的信号执行下去危险区HazardousArea样品不合格，回流阀保持常开，排放阀不动作样品合格，回流阀关闭，排放阀打开OilDischargeMonitoringEquipment系统参数SystemParameter系统电源/SystemPowerSupply：AC220V±10%,50Hz±5%环境温度/CircumstanceTemperature：0～50℃环境湿度/CircumstanceHumidity：80%测量范围/MeasuringRange：0～1000ppm测量精度/Measuringaccuracy：±10％FS反应时间/ReactionTime：40秒适用油种/Applicableoil：MEPC108（49）显示/Display：6monochromeLCD输入/输出/Input/Output：RS485Serialport航速输入/NavigationalSpeedinput：200Pulse/MinGPS定位/GPSPositioning：NMEA0183数据存储/Datastorage：InternalmemorystoreOilDischargeMonitoringEquipment计算机控制单元ComputerControlUnit信号采集单元SignalPickupUnits采样泵控制单元Samplingpumpcontrolunit油份浓度测量单元OilContentMeasureUnits流量计探测器Flowmeterdetector取样头SamplingProbe取样泵SamplingPump冲洗水CleaningWater机舱EngineRoom泵舱PumpRoom非危险区NonHazardousArea危险区HazardousArea去污油水舱ToSloptank排舷外OverboardDischarge计程仪SpeedLogGPS信号GPSSignal排放阀控制单元DischargeValveControlUnit流量测量单元FlowMeasureUnits计算机控制单元ComputerControlUnit计算机控制单元由显示屏、蜂鸣器、USB接口、指示灯、越控开关和电源开关组成。TheComputerControlunitconsistsofDisplay、buzzer、USBport、IndictorLamp、overrideswitchandpowerswitchetc.显示屏/Display指示灯/IndicationLampUSB接口/USBport蜂鸣器/Buzzer越控开关/Overrideswitch电源开关/Powerswitch危险区HazardousAreaOilDischargeMonitoringEquipment计算机控制单元ComputerControlUnit信号采集单元SignalPickupUnits采样泵控制单元Samplingpumpcontrolunit油份浓度测量单元OilContentMeasureUnits流量计探测器Flowmeterdetector取样头SamplingProbe取样泵SamplingPump冲洗水CleaningWater机舱EngineRoom泵舱PumpRoom非危险区NonHazardousArea危险区HazardousArea去污油水舱ToSloptank排舷外OverboardDischarge计程仪SpeedLogGPS信号GPSSignal排放阀控制单元DischargeValveControlUnit流量测量单元FlowMeasureUnits信号采集单元SignalPickupUnit信号采集单元位于机舱内。主要是采集油份浓度和排出流量。同时接收来自计算机控制单元的命令，控制排放阀门的动作，取样泵的启动和停止以及油份浓度探测器的清洗。TheSignalpickupunitislocatedinEngineroom.Mainjobispickuptheoilcontentandthedischargeflowrate,Controlthedischagevalvemovement,Start/Stopsamplepumpandclearingthesensorofoilcentent.危险区HazardousAreaOilDischargeMonitoringEquipment计算机控制单元ComputerControlUnit信号采集单元SignalPickupUnits采样泵控制单元Samplingpumpcontrolunit油份浓度测量单元OilContentMeasureUnits流量计探测器Flowmeterdetector取样头SamplingProbe取样泵SamplingPump冲洗水CleaningWater机舱EngineRoom泵舱PumpRoom非危险区NonHazardousArea危险区HazardousArea去污油水舱ToSloptank排舷外OverboardDischarge计程仪SpeedLogGPS信号GPSSignal排放阀控制单元DischargeValveControlUnit流量测量单元FlowMeasureUnitsTransmissionlight入射光源Refractedlight反射光透射光折射光IncidentlightsourceReflectedlight油分浓度分析单元里设有一个带有光学测量器件的油分浓度测量装置，从采样泵来的样水由测量装置的入口进入，然后从出口流回到排水总管。光学测量器件将流过测量装置的样水中含油量的变化转换成相应的光信号，并通过光纤传递到油份浓度计（OCT-1）。在油份浓度计里，光信号被转换成RS485信号传送到计算机单元。Itisequippedwithopticalelementsformeasuringoilcontentinsamplingwater.Thesamplingwatercomingfromsamplingpumpentersintotheinletofoilcontentmeasuringunitandflowsbacktomaindischargepipefromoutlet.Theopticalmeasuringcellconvertstheoilcontenttransformationofsamplingwaterpassingthroughthemeasuringunitintoproportionalopticalsignalandthensendsittooilcontenttransmitter(OCT-1)byopticalcable.ThisopticalsignalisconvertedintoRS485signalinOCT-1andthentransmittedthissignaltothecomputerunit.危险区HazardousAreaOilDischargeMonitoringEquipment计算机控制单元ComputerControlUnit信号采集单元SignalPickupUnits采样泵控制单元Samplingpumpcontrolunit油份浓度测量单元OilContentMeasureUnits流量计探测器Flowmeterdetector取样头SamplingProbe取样泵SamplingPump冲洗水CleaningWater机舱EngineRoom泵舱PumpRoom非危险区NonHazardousArea危险区HazardousArea去污油水舱ToSloptank排舷外OverboardDischarge计程仪SpeedLogGPS信号GPSSignal排放阀控制单元DischargeValveControlUnit流量测量单元FlowMeasureUnits流量测量单元FlowMeasurelUnit阿牛巴流量传感器有5个测量孔，用于检测流体的动压和静压。测量信号通过高压信号管路和低压信号管路传递到差压变送器。并将压力信号转换成与排水泵排量相适应的4—20mA的电流信号,传送到计算机单元。TheANNUBARflowmeterhasfive(5)measuringportswhichareusedtodetectthedynamicandstaticpressurefortheliquid.AndthedetectingsignalsaretransmittedtotheDPtransmitterthroughhighpressuresignallineandlowpressuresignalline.andconverttoasignalof4-20mAthatisproportionaltothedischargerateofdischargepump,andsendsittot
