水电厂技术供水滤水器的研制

介绍了水电厂技术供水滤水器的设计要求、滤水器内的水流流态分析以及双刃式全自动免清洗滤水器的原理、结构和特点。全自动免清洗滤水器具有较强的清污能力，对水中含杂质较多的水源，其效果尤为明显，可以进行远程操作、自动操作、现地自动操作、现场电手动操作和现场机械手动操作，其自动清污、排污可在线进行，不影响机组正常技术供水。

DEVELOPMENT OF AUTOMATIC CLEARING-FREE WATER PURIFIER FOR HYDROPOWER PLANTS

The design requirement of water purifier for technical water supply in hydropower plants is introduced. The current condition of water purifier is analyzed, and the principle, structure and characteristic of the automatic cleaning free water purifier are described. The water purifier has the ability of pollutant removal, especially for water sources of a large quantity of impurities. It can be operated remotely, automatically, in situ automatically, in situ manually, and in situ mechanically. Its function of automatic pollutant removal and pollutant discharge can be realized on line, so the normal technical water supply is not affected.
