ACCU主机辅助（备用）泵的控制问题？

justsun

ABS， ACCU主机辅助（备用）泵的控制,  4-9-4/13.5 Automatic Start and Changeover里面说，主机系统的备用泵浦要求能自动启动和变换
In the event of detecting low or the loss of system pressure, as specified in 4-9-4/Table 3A through
4-9-4/Table 5 and 4-9-4/Table 7A (in “Auto start” column), automatic startup of and changeover to
the standby pumps, which are essential to maintain the running of the propulsion machinery, are to be
provided.

但在ACC中，他们要求要有 远程启动和停止 功能
13.13 Propulsion Auxiliaries (2007)
The centralized control station is to be provided with means to remotely start and stop auxiliary
pumps associated with the operation of the following:
• Propulsion engine
• Electrical power generators
• Controllable pitch propellers
• Propulsion boilers and boilers supporting propulsion (including power generation)
• Fuel oil transfer system
Automatic transferring of vital auxiliary pumps, where fitted, is to be alarmed at the centralized
control station.

是不是ACCU中就不需要 远程启动和停止功能呢？ 只需要自动功能，然后给控制站一个运行和故障报警信号就可以了？？
还是远程加自动两个都要？

请指点，谢谢

我的理解是2个都需要，只不过无人机舱进一步的要求是需要自动启动！

远程启停和自动切换启动是两个不同的概念，一般来说为了保护主机，对为其服务的泵浦都会设置这两个功能。
远程启停一般是指在集控室就能对泵浦进行启停，在集控室的控制台上有启停按钮，
自动切换启动是指在泵的出口管路上有一压力继电器用来检测出口压力，当在用的那台泵由于某种故障而导致其出口管路流体压力降至压力继电器的设定值时，备用的那台泵会自动启动以维持主机的正常运转，并同时发出“备用泵启动”的报警。

楼上的说的很明白
