部件设计规范翻译-中英对照
鼓形滤网密封的选择和位置是经过优化的，密封件设在滤网外表面上，可以不停机检查。密封件有独立的连接系统，侧向密封采用模块化设计。
滤网的检修期应在三个星期以内。
冲洗水收集槽设在滤网内部向上旋转面那一侧，在设备运行中可以靠近。收集槽的形状精心设计，可以排出所有污物。
每个网片沿着鼓形滤网外圆曲线铺设。在设备运行过程中，人员可以从外面观测网片的表面检查脏污情况而不受喷溅危险。网片在滤网前后压差达到100bar时不发生永久变形。使用铁丝网时，网片不形成大于2.5mm的凹穴。
网片及捞污斗收集到的污物会构成阻塞危险，所以必须把他们冲洗到排水槽中排走。
与冲洗直接动作无关的部件（如支承）必须尽可能光整。
冲洗管路处过道和进入口在操作平台6.30m处。
虽然轴承实际上不浸没在水中，但还是被设计成可在水中运行。
主轴通过两个轴承来支撑整个鼓形滤网结构。鼓形滤网设计时考虑滤网前后的压力差为2m。
固定件通过防松螺母连接，不采用钻孔螺纹。
鼓形滤网压力损失探测系统必须设计成不被脏污。
自动清洗过滤器网孔为0.5mm，带有压差仪表。
没有包括在小电气部件中的设备必须获业主审核。
e） 阴极保护系统设计规格书
阴极保护原则：保护HPX泵房内的设备采用牺牲阳极块和外加电流法进行阴极保护，牺牲阳极块按5年有效期设计；HPX泵站外的设备采用牺牲阳极块进行保护，牺牲阳极块按15年有效期设计。
RCC-E-1993版，规定了设备的规格、环境条件、组成元件的标准和规则、电气设备的选择采购以及试验方法。
联箱必须设在所连设备附近的地面上，为防水户外嵌墙式。
2.3.6 施工相关的规格书
所有设备施工中用到的所有材料必须保证其设备功能，并能抵御自然老化带来的影响。根据流体性质来选择材料，以保证防腐。
在选择CFI系统设备的材料时，必须考虑该材料能抵抗海水腐蚀以及海生物的增殖。
采用球墨铸铁，不能采用焊接铸件。所有主要的球墨铸铁部件要经过稳定处理。如果一些部件需要由塑料制成，那么必须是在提供了所有的文件支持的情况下才能被采用，所有材料都要进行检测以确定其在使用时期内断裂强度和强度随时间的变化情况。
2.3.7 维护
连续运行只需要目视检查。维护和检验在停堆期内进行，频率为一到两年之间。供应商必须提供所有维护和检修所需工具。
