3．安全保护装置
Safeguard device
R6160 系列柴油机的安全保护装置只应用在船用柴油机上，220kW 以上船用机型还带有超速
保护功能。此装置由温度报警器、机油压力报警器、油温报警器、转速传感器以及湿式电磁换向阀
（仅对 220kW 以上船用柴油机）、连接电线和柴油机保护装置组成。要求使用 24V 直流电源。
The safeguard device for R6160 series diesel engine is applied to the marine diesel engine only,
furthermore, the marine engine which power is above 220kW has overspeed protection. The device
is composed of temperature alarm, oil pressure alarm, oil temperature alarm, speed sensor, wet-type
solenoid switchover valve (only for marine engine which power is above 220kW), connecting wires and
protective device of diesel engine. 24V DC power is required.
安全保护装置都能准确地显示柴油机地各种参数，并在柴油机运行中出现异常情况时能进行
报警。
The safeguard device can display various parameters of your engine accurately, and give an alarm when
any abnormal condition appears during diesel engine operation.
功能
Functions
1．检测功能
Monitoring an measuring ability
船用柴油机一般使用安装在柴油机上的机械式仪表和测量保护装置形式（便于操作）。机械式
仪表可显示柴油机转速、水温、油温、机油滤清器前压力、主油道压力。测量保护装置可显示柴油
机转速、运行时间和报警信号。
Marine diesel engine is usually furnished with mechanical type instrument and measurement protective
device which are easy to operate. Mechanical type instrument can indicate diesel engine speed, water
temperature, oil temperature, pressure before oil filter and pressure of main oil passage. Measurement
protective device can display diesel engine speed, running time and alarm signal.
2．当柴油机的运行工况超越报警设定值时，监控系统会发出断续声光报警信号，直到按下消
音键后，才会消除报警信号。该报警型号提示操作者柴油机工况已经或曾经超越报警设定值。
When operating condition of your diesel engine exceeds the setting alarm value, monitoring system will
generate pulsed sound and /or visual alarm until you press silencing button. This alarm prompts you the
operating condition of your engine has already or on one occasion exceeded the setting alarm value.
当船用柴油机转速超过设定值时， 保护装置自动进入“风浪”档工作状态，保护装置通过控
制停车电磁阀的开闭，使柴油机转速在规定的范围内变动，直到转速稳定。
