Operation requirements 运行要求
? Operation
? 运行

1. Steam admission devices (bled steam, live steam and auxiliary steam lines) shall be operated by remote control from the Central Control Room.
1. 蒸汽进入装置（废蒸汽、新鲜蒸汽和辅助蒸汽管道）应通过中央控制室进行远程控制操作。

2. The drain valves for bled steam lines if there are any shall operate under automatic control. The control and operation shall be carried out in the classic manner.
2. 废蒸汽管道的排水阀（如果有）应在自动控制下运行。控制和操作应以标准方式实施。

3. A control system shall be studied to avoid an excessive deaerator depressurization, which could cause feedwater pumps' cavitation during transient conditions, the most unfavorable case being total load rejection from full load.
3. 应研究和设计一个控制系统，避免可能造成给水泵在瞬态条件下发生气穴的除氧器过度降压，最不利的情况就是全部负荷从满负荷中甩出。

Beijing Chinese Subtitling Translation Service Agency has translated many technical documents about bled steam, live steam and auxiliary steam lines.
华译网上海翻译公司曾经翻译过大量有关废蒸汽、新鲜蒸汽和辅助蒸汽管道的资料文件。

4. In addition to normal level control detectors the tank shall be equipped with a specific water level control device in order to guaranteed that a minimum water volume is in the deaerator during transients, and to avoid drying of the tank.
4. 除了正常液位控制探测器外，储罐还应配备一个特殊的水位控制装置，以保证除氧器中瞬态条件下最低的水位，并避免储罐排干。

5. Control valve failure shall not result in plant shutdown.
5. 控制阀故障不应导致电站停运。

6. Valve position indicators shall be provided in the Central Control Room.
6. 中央控制室中应提供阀门位置指示器。

7. Automatic controls shall be provided, with indication in the Central Control Room, and the possibility of manual operation either from the Control Room or locally for:
7. 在中央控制室中应提供以下操作的自动控制装置及指示，并且能够从中央控制室和就地对以下操作进行手动控制：
- control of live steam make-up (pressure control),
- 新鲜蒸汽补充的控制（压力控制）
- control of feedwater inlet flow.
- 给水入口流量的控制
- control of feedwater volume in the deaerator (level control),
- 除氧器中的给水水位的控制（液位控制）
- control of auxiliary steam supply (feedwater deaerator pressure pegging line).
- 辅助蒸汽供应的控制（给水除氧器压力限位线）

8. The Supplier shall supply the instrumentation necessary for the correct operation of the deaerator and connected equipment.
8. 供方应提供除氧器和连接设备正确运行所必需的仪器仪表。
