描述
DGU 8800E是Norcontrol Automation AS生产的数字调速单元，主要用于船舶等领域的发动机调速控制，以下是其相关产品详情：
基本信息
制造商：Norcontrol Automation AS
类型：数字调速单元
产地：挪威
重量：约10.5-11kg
技术参数
输入信号：可接收来自转速检测装置、扫气压力传感器等的信号，如转速信号、压力信号等。
输出信号：输出控制信号至执行机构，用于控制发动机的油门拉杆等，以调节发动机的转速。
功能特点
精确的速度控制：通过飞轮处安装的传感器监测转速，并根据设定转速和实际转速的差异进行调节，稳定状态下的转速波动率可低于0.1%。同时，设有联轴节扭振滤器，可滤掉速度信号中的扭振信号，保证速度的精确控制。
全面的控制功能：不仅可以精确地控制柴油机的转速，还具有大量的限制功能，可在各种运转条件下使柴油机不承受异常负荷，保证柴油机安全可靠地运转。在带有轴带发电机的船上，还可良好地控制轴带发电机和柴油发电机组间的负荷转移。
多种操作模式：具有正常（NORMAL）模式、空闲（IDLE）模式、设定值（SETPOINT）模式、试验（TEST）模式、校验（CALIBRATION）模式和自检（SELF TEST）模式等，可根据不同的要求由操作者选择机器的运转模式，保证发动机一直处于最优化状态运转。
特别控制模式：具备恒定供油量（CONSTANT FUEL）控制模式、恶劣海况（ROUGH SEA）控制模式、燃油设定值（FUEL SETPOINT）直接控制模式等特别控制模式，以适应不同的工作场景和需求。
结构特点
安装方便：可安装在标准的19英寸机架上，内部有用于低压配电的电源模块，面板部分允许操作人员直接控制系统功能，过程信号都连接到标准端子板，通过扁平电缆轻松连接到单元。
模块化设计：采用模块化结构，如包含I/O处理器卡、DCU主板等，便于维护和更换部件。
The DGU 8800E is a digital speed control unit manufactured by Norcontrol Automation AS,primarily used for engine speed control in marine applications.The following are product details:
Basic Information
Manufacturer:Norcontrol Automation AS
Type:Digital SpeedControl Unit
Origin:Norway
Weight:Approximately 10.5-11 kg
Technical Parameters
Input Signal:Receives signals such as speed and pressure from speed sensors and scavenging air pressure sensors.
Output Signal:Outputs control signals to actuators,such as the engine throttle lever,to adjust engine speed.
Features
Precise SpeedControl:A sensor mounted on the flywheel monitors speed and adjusts it based on the difference between the set and actual speeds.Speedfluctuations in steady state are less than 0.1%.A coupling torsional vibration filter removes torsional vibrations from the speed signal,ensuring precise speed control.Comprehensive Control Functions:Not only can the engine speed be precisely controlled,but a wide range of limiting functions are also included to prevent abnormal engine loads under various operating conditions,ensuring safe and reliable operation.On vessels equipped with shaft generators,load transfer between the shaft generator and the diesel generator set can also be effectively controlled.
Multiple Operating Modes:The operator can select the correct operating mode based on various requirements,including Normal,Idle,Setpoint,Test,Calibration,and Self-Test,ensuring optimal engine operation at all times.
Special Control Modes:Features include Constant Fuel,Rough Sea,and Fuel Setpoint direct control to accommodate diverse operating scenarios and requirements.Structural Features
Easy Installation:Mountable in a standard 19-inch rack,it features an internal power supply module for low-voltage power distribution.The panel allows operators to directly control system functions.Process signals are connected to a standard terminal block,easily connected to the unit via a flat cable.
Modular Design:The modular design,including the I/O processor card and DCU mainboard,facilitates maintenance and component replacement.
