9、台 SED 除盐水泵能够满足用水量达到峰值时的需要。一台 SED 除盐水泵连续运行。第二台 SED 除盐水泵根据安装在泵出口母管的流量测量信号（节流孔板）实现自动启停。第三台 SED 除盐水泵处在备用状态。除盐的补水以及 SED除盐水泵的启停可以通过系统上位机(LCD)进行人工操作。当任何的操作及故障发生时，应当在除盐水车间室和主控室内触发。除盐水位、除盐水出口母管流量、导电度、PH 值和电动阀门状态信号等能够在除盐水车间室内的 PLC系统操作员站(LCR) 上实时。在主控室 DCS 操作员站（KIC）上也能实时监视除盐的水位。LCR(PLC)通过通讯电缆与KIC(DCS)。6.1.1补充水M

12、 operation shall shut down automatically when the water level in the SED tank is high or very high (in case of failure of high level) and if there is no request for SED water. and close the value 303VD(304VD).-Make-up can be forced by manual opening of make-up value from LCR of demineralized water p

13、roduction control system. Shutdown of the make-up system can also be forced by manual closing of make-up valve from demineralized water production control system. In automatic mode, the make-up valve will close automatically to stop make-up, when the water level in the tank reaches high level 1, and

14、 open automatically when water level in the tank reaches low level 1.Any make-up request which is not satisfied after 30 seconds to enable the demineralization line or lines to begin production, trips a SED storage fault alarm (920KA) on the demineralized water production control system. This fault

15、ismonitored on the MCR LCD as 920KA: SED fault.SED补水和 SER补水一样，都来源自除盐水生产系统(SDA)。根据水位自动补水量。-当水位低1 值时，打开SED 除盐阀303VD(304VD)，启动一列SDA。-当水位低 2 值或低 3 值（低 2 值信号故障时）时，启动第二列 SDA。当水位恢复到低 1 值时，在第一列 SDA 在运行的情况下，第二列 SDA 延时 30 秒停止。-当水位高 1 值或高 2 值（高 1 值信号故障时）时，SED 除盐阀 303VD(304VD)自动关闭。当水位高 2 值时，运行中的 SDA 自动停运。-运行可以通

16、过除盐水系统操作员站（LCR）手动打开阀实现强制补水。强制停止补水也可以用同样方法实现。在自动模式下，阀能自动在水位高 1 值时关闭，低 1 值时打开。补水系统开始运行 30 秒后，任何补水需求都时，在除盐水系统操作员站（LCR）上触发“SED 除盐故障”（920KA）信号。这个信号同时出现在主控室 DCS 操作员站（KIC）上。6.1.2 SED 除盐水泵Only one pump called master pump is in operation during normal operating conditions. When the water request in SED syste

17、m is great, the second pump called hack-up pump can be started up for operation automatically according to the flow in the header of pump outlet. The master pump and back-up pump are selected in AUTO ON position. The third pump, stand-by pump, is also in AUTO ON核岛除盐水分配系统(SED)系统手册第 6 章A 版 3/14positio

18、n. But it can be in AUTO OFF position.The master pump for operation is selected by operator via selector switch on LCR of the demineralized water production control system. The other pumps will then become automatically back-up pump and staid-by pump.The back-up pump shall be started up automaticall

19、y when the flow in the header of pump outlet is higher than the set point (flow increasing: high differential pressure). The back-up pump shall be shut down automatically when the flow in the header of pump outlet is lower than the set point (flow decreasing: low differential pressure). If the maste

20、r pump becomes out of operation because of failure, as soon as the master pump is tripped, the back-up pump shall be started up automatically.The alarm signal service pressure abnormal in the header of SED pump outlet is sent out when the pressure in the header of pump outlet is low 2. The pumps are

21、 all tripped.Stop all demineralized water pump when water level is low 3, or the flow at the pump discharge is H2. Only when water level is not L3 and the flow at the pump discharge is not H2, demineralized water pumps are permit to start.在正常工况下，只有一台泵运行，称为主泵。当 SED 用水需求增大，即根据泵出口母管流量，第二台泵作为备用副泵自动启动。主泵

22、和副泵都能选择在AUTO ON状态。第三台泵，称为紧急备用泵，能够设置在AUTO ON和AUTOOFF状态。运行可以通过除盐水系统操作员站（LCR）上的选择开关选定某台泵作为运行主泵。选择之后，其余两台泵自动设定为备用副泵和紧急备用泵。 当除盐水泵出口母管流量高 1 值时，备用副泵自动启动。当流量低 1 值时，自动停止。当运行主泵故障停止时，备用副泵同样自动启动。当泵出口母管低 2 值时，泵组全停。当水位低 3 值或泵出口母管流量高 2 值时，泵组全停。只有当水位不在低 3 位和泵出口母管流量不在高 2值时，泵组才启动。6.1.3 仪表信号The level of each tank and
