3、al operation一旦船只到达码头，主机车钟命令"Finish with engin第给出。此命令将自动停 止泵站并使安全阀块上的电磁阀有效，这将转换每个顶部拉撑液压缸到“low这样顶部拉 撑液压缸立即将其工作压力从最高17 bar降低到大约2 bar。Upon arrival in port the engine telegraph order“ Finish with engine “ is given.'order automatically stops the pump station and activates the solenoid valves in t

4、he relief valve blocks, which shift each top bracing cylinder totop b radow cylind ersethus immediately reduce their work pressure from max. 17 bar to approx. 2 bar.起动前，主机车钟命令" Stand byT给出。此命令将自动起动泵站并使安全阀块 上的电磁阀失效，每个顶部拉撑液压缸将转换到“ high且液压缸内的工作负荷在停止状态下将增加到大约5 bar,而当主机起动后将增加到最高17 bar。Before start-u

5、p, the enginetelegraph order “ Stand by “ is given. This order automatically starts the pump station and de-activates the solenoid valves in the relief valve blocks. Each top bracing cylinder shifts to“ high ” , and the work load in the tojbracing cylinders will build up to approx. 5 bar at standsti

6、ll, and max. 17 bar when the engine is started.在正常设定状态下，泵站上的压力表在海上运行期间的读数约为5 bar。At normal setting, the pressure gauge on the pump station will read approx. 5 bar during operation at sea.控制箱状态：Control box status:山开关打开Main switch On 电源指示灯接通(白色Power lamp indication On (White 压力开关置于高压Pressure switch Hi

If the switch is in low position, the work load will be 2 bar during operation of the main engine, and the top bracing is considered inactive.液压泵选

10、择开关Pump Selection Switch位置1: “ K”Pos.1: “ Pump 1 ”系统起动时，此模式选择1号泵。此模式为紧急模式，即:液压泵将持续运转并尽 量建立压力。在此模式下，将不会报警，且不考虑排出管压力。This mode selects Pump 1 during start-up of the system. This mode is meant as an ernf cy mode, i.e. the pump will continue running and try buiidg up a pressure. The alarm will not be ac

11、tivated in this mode, irrespective of the pressure in the outlet pipe.位置2:自动”Pos.2: “ Auto ”系统起动时，此模式选择1号泵。在系统内建立油压允许延时，如果60秒后压力 开关的压力没达到1.4 bar , 2号泵将起动；如果另一个60秒后压力开关的压力还 没 达到1.4 bar, 2号泵将停止，且本地及集控室内都将以红灯给出报警指示。如果压力下降，压力开关将在0.9 bar时断开，并将执行上述程序This mode selects Pump 1 during start-up of the system.

12、A time relay allows the oil pressure to build up in the system. If the pressure has not reached 1.4 bar at the pressure switch after 60 seconds, Pump 2 will start. If the pressure has not reached 1.4 bar at the pressure switch after another 60 seconds, Pump 2 will stop and the alarm indication will

13、be given locally and in the engine control room by red lamps.With falling pressure, the pressure switch breaks at 0.9 bar, and the above sequence will be executed.位置3: “舒泵”Pos.3: “ Pump 2 ”系统起动时，此模式选择2号泵。在系统内建立油压允许延时，如果60秒后压力 开关的压力没达到1.4 bar,泵将停止，且本地及集控室内都将以红灯给出报警指 示。This mode selects Pump 2 during

14、start-up of the system. A time relay allows the oil pressure to build up in the system. If the pressure has not reached 1.4 bar at the pressure switch after 60 seconds, the pump will stop, and the alarm indication will be given locally and in the engine control room by red lamps.本地起动/停止按钮Local Start

15、/Stop Buttons起动/停止所选用的供油泵。对于起作用的油泵，绿色指示灯将接通。顶部拉 撑液压 缸内的压力取决于高/低压力开关的位置。Start/stop the selected oil supply pump and turn on the green lamp for the active pump. The pressure in the top bracing cylinders depends on the position of the High/low pressure switch.复位按钮Reset Button对于自动模式复位两个时间继电器，并关闭本地和遥控报警指
