闸门及导槽技术规格翻译-中英
1)闸门
闸门由钢板和型钢焊接而成,由预制截面的弹性氯丁橡胶密封条沿四周密封,并用压板和紧固件固定。闸门为静水启闭,只承受单向水压力,采用单向止水。每个闸门带有平衡阀。平衡阀的动作是升降程序中的一部分,抓梁吊钩抓合后,在提升闸门之前提升并打开平衡阀引水以平衡闸门两侧压力。当两侧压力达到平衡时,再提升闸门。闸门在侧面导槽中由滚轮和导向块定位,把橡胶密封条压在密封面上密封。闸门上带有触底探测装置以防止在闸门下降过程中被卡在导轨上使抓梁吊钩意外脱扣。
2)导槽
导槽包含密封角铁、底槛、门楣和上端导轨角铁,均由角钢制成用螺栓和调整螺母固定。锚板在一次灌浆中安置。在安装时,螺栓焊接到锚板上,用调整螺母将导槽及各个部件精确找正对准。导槽材质为耐海水腐蚀的,导槽高度为全槽结构。
3)防腐要求
采用防腐涂料加牺牲阳极块联合保护,设计总的使用年限为60年。
4)厂址数据

7) 泄漏
闸门是水密性的,但在出现低水阻或密封构件被污物垫塞时会发生一些泄漏。当闸门完全浸没时每米密封长度的最大泄漏率为0.05L/s,部分浸没时最大泄漏率为0.l L/S。
8) 起重能力
设备数据参数表中给出的重量是闸门的自重。在起重时,为了克服闸门与密封面间的摩擦和在导槽上的咬和黏附作用,建议需要升降的重量按闸门自重的两倍估计。
9) 闸门自动抓梁装置技术规格
自动抓梁装置在闸门升降过程中可以自动抓合和脱扣。自动抓梁装置两端带有导向块使其在导槽中定位并与闸门升降点对准。吊钩与决定其开合偏差的转轴组件相连接。在升降过程中,转轴组件的精确动作可使吊钩与闸门自动抓合或脱扣。抓梁带有一个连锁装置以防止在测量装置动作前升降杆与闸门脱扣。
c) Technical specification of strobe and guide barrel
1)Strobe
A strobe is welded by steel plate and steel section, which is sealed around by electrometric neoprene seal with preformed section and fixed by a pressure plate and a fastener. The strobe shall apply static water open-close, only bearing unidirectional pressure and adopting unidirectional water stopping. Each strobe is set with a balance valve. The movement of balance valve is a part of lifting and lowering processes. After the lifting hook of grabbing beam has grasped, it is required to lift and open the balance valve for drawing water to balance the pressure on both sides of strode before exalting it. When both sides have been balanced, strode will be lifted. A strode is positioned by a trolley and a guide block in the guide barrel on one side, pressing rubber seal on a sealed surface for sealing. The strode is installed with a bottom finding detection facility to prevent strode from being blocked on guide rail during descending, causing lifting hook of grabbing beam to escape away accidentally.

2)Guide barrel
The guide barrel consists of a sealed angle iron, bottom sill, door head and an upper guide rail angle iron, which are all made of angle steel and fastened by bolts and adjusting nuts. An anchor plate is installed during one time of grouting. During installation, the bolt is welded into the anchor plate, aligning the guide barrel and each part correctly with the adjusting nut. The material of guide barrel is seawater corrosion resistant and the height of guide barrel includes the whole structure of the guide barrel.

3)Anti-corrosion requirements
Combined protection by using preservative coatings and sacrificed anode is applied and the total service life is designed to be 60 years.

4)Data of plant site
 Tidal levels of outer-sea are:
SEC designed highest tide level:                7.58m
  CRF designed highest tide level:    4.54 m
  CRF designed lowest tide level:    -1.47m
   SEC designed lowest tide level:   -3.35m  
 The water levels of front tank(sea reservoir)of pump room are:
 CRF designed lowest water level:          -6.72m
   SEC designed lowest water level:  -8.00m  
5)Equipment data
          The elevation of orifice of strobe:                  
Top:                           -7.0m *
Bottom:                 -11.5m*
    Elevation of operation platform    8.0m*
 Width of water channel:                    5.5m*
 Number of strobe:             16(8 for each unit)
 Width:                   5.5m*
 Height:                   4.5m*
 Weight:                 
 Designed head difference:               9.1m*
 Number of guide barrel:            16 set(8 for each unit)
 Length of guide barrel:                  20.0m*
6) Engineering material
 Structure of strobe:              Carbon steel
 Balance valve:               Carbon steel
 Seal:                  Neoprene
Guide barrel:                            316L
7) Leakage
The strobe is water tight, but leakage may occur when low water resistance takes place or the sealed component is padded by dirt. When the strobe is completely immerged, the maximum leakage rate of seal length per meter is 0.05L/s, and the maximum leakage rate of seal length per meter is 0.l L/S if it is partly immerged.
8) Lifting capability
The weight shown in the parameter table of equipment data is the dead weight of strobe. During lifting, it is suggested that two times of dead weight for lifting should be reuired to overcome the friction between strobe and seal surface as well as bite force and adhesive action on guide barrel.
9) Technical specification of automatic beam grabbing device for strobe
The automatic beam grabbing device can grasp and trip automatically during lifting of strobe. Guide blocks are installed on both sides of the automatic beam grabbing device for positioning in the guide barrel and aligning with rise-fall dot of strobe. The lifting hook is connected to components of rotating shaft which decides its retractable deviation. During lifting, the accurate action of rotating shaft will help the lifting hook and strobe grasp or trip automatically. The grabbing beam is set with an interlocking gear to prevent lifting bar and strobe from tripping before the movement of measuring device.
