English to Chinese Tech/Engineering Construction / Civil Engineering 泵

The bypass is slowly closed once the pump has reached the working rpm; the flush ing fluid starts to move slowly until the bypass is closed completely and the required flow rate has been reached. Today, the following devices are used to start the pump:

- Fluid turbo couplings
- Softstarters
- Frequency converters

只要泵达到工作的每分钟转数，旁道会缓慢地关闭；在旁道完全关闭和达到需要的流速前，液体还会开始缓慢地移动。现在采用以下措施来启动泵：

- 液体涡轮结合
- 轻柔的启动装置
- 频率转炉

谢谢。
