水电站清污机特点:要有综合的清污性能;能在恶劣工况下安全、可靠运行;保证水电站的核心发电参数持续稳定。能满足上述三个特点的清污机，称为水电站专用清污机，属于清污机家族中限制条件最多、技术难度最大、综合性能、安全性能最高的清污机机型。有选抓斗式清污机、齿耙式清污机作为水电站清污机型的，但这两种机型局限性比较大，很难兼顾水电站特殊技术和工况要求的方方面面，设计上往往只能照顾到突出的一方面或两方面。水电站大多选耙斗式为主，相对均衡的照顾到多方面的技术和工况要求，近年来以增力耙斗式和浮动加压耙斗式为水电站清污机的主选机型，设计上和使用上各种难题都比较容易解决。

The characteristics of the power station cleaning machine are: comprehensive cleaning performance, safe and reliable operation under harsh conditions, and ensuring the core power generation parameters of hydropower station are stable. The cleaning machine, which can meet the above three characteristics, is called a special cleaning machine for the hydropower station. It belongs to the cleaning machine with the most restrictive conditions, the greatest technical difficulty, the comprehensive performance and the highest safety performance in the family of the cleaning machine. The selected grab cleaning machine and the tooth rake type cleaning machine are used as the cleaning machine for the hydropower station, but the two types are very limited. It is difficult to take into account all aspects of the special technical and working conditions of the hydropower station, and the design can only take care of the outstanding one or two aspects. Most of the hydropower stations are mainly selected rake type, and it is relatively balanced to take care of many technical and working conditions. In recent years, the design and use of various difficult problems are easy to be solved by using the force increasing rake type and the floating pressure rake type as the main selection model for the cleaning machine of the hydropower station.

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 flow 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 cleaner to realize 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. If we can't stop the water or even lose the load, we must finish the function of cleaning up the power station and improve the economic, safety and management benefits of the hydropower station. The working requirements and manufacturing difficulty of the cleaning machine of the hydropower station are the highest among all cleaning machines, which belong to the 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.

水电站清污机设计要求:以水电站的水头、流量、过栅流速等水电站设计参数作为清污机的设计要求参数，如果机型和参数选择不对，达不到效果，浪费投资;功能要全、性能要好、体积还要小，空间布置适应性要强，为节省新建电站的基建投资，及老电站技改提供可能性。

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 can be provided.
