水电站的特殊技术和工况要求:
The special technical and working conditions of the hydropower station:
1. 水电站在设计和运行中，有特定的水头、流速、流量、水流品质等的核心参数要求。普通清污机能清污，但不保证核心发电参数。
1. in the design and operation of hydropower stations, there are
specific requirements for core parameters, such as head, velocity, flow
rate and water quality. The general cleaning function can clear the
dirt, but does not guarantee the core power generation parameters.
2. 水电站在发电运行中，面对的是体积、形状、重量各不相同的不同种类的水体垃圾，有同时完成大、小，刚、柔，常、异各形垃圾"一网打尽"。普通清污机难于实现塑料袋、大树杆、异形的竹、树枝同时清理。
2. the hydropower station is facing the different kinds of water
waste in different types of volume, shape and weight in the power
generation operation. It is difficult for ordinary cleaning machines to
clean up plastic bags, big sticks, special shaped bamboos and branches.
水电站必须带机清污。不能停水、甚至在不能减负荷的情况下要完成水电站清污机能提高水电站经济、安全和管理效益。水电站清污机的工作要求和制造难度是所有清污机中最高的，属于非标准设计。
The power station must take the machine to clean up the pollution.
It is necessary to complete the cleaning function of hydropower station
and improve the economic, safety and management benefits of hydropower
stations without stopping the water or even reducing the load. The
working requirements and manufacturing difficulty of the cleaning
machine are the highest among all cleaning machines, which belong to
non-standard design.
水电站清污机的特点:1、适应性强，能适应工况复杂，流速、流量大，含侧向水流大;2、清污功能强，必须能解决水体垃圾种类多，数量大等问题;3、可靠性高，能连续工作，要保证清污机不间断发电过程中同步工作。4、差异性，根据不同流域、不同环境、不同水电站专门设计、制作。
The characteristics of the cleaning machine of the hydropower
station: 1. It has strong adaptability, can adapt to the complicated
working condition, the flow rate, the flow is big, the lateral flow is
big, 2, the clean pollution function is strong, it must be able to solve
the problem of many kinds of waste water, high reliability and
continuous work, so as to ensure the synchronous work in the process of
uninterrupted power generation. 4, the difference is designed and made
according to different basins, different environments and different
hydropower stations.
The design requirements of the cleaning machine for hydropower
stations are as follows: the design parameters of hydroelectric power
stations, such as water head, flow rate, flow velocity, and so on, are
used as the design parameters for the design of the cleaning machine. If
the selection of the machine model and parameters is wrong, it can not
achieve the effect and waste the investment; the function should be
full, the performance is better, the volume is smaller, the space
arrangement is adaptable and the new construction is saved. The capital
construction investment of the power station and the technological
transformation of the old power station are possible
