摘　　要：根据已有的使用情况，从水轮机顶盖取水作为机组技术供水水源存在着一些问题，为此，从上漏环间隙及顶盖取水的水量和水压，顶盖取水管和稳压池的布置，顶盖取水的运行方式及注意事项等方面，探讨了中小型水轮机从顶盖取冷却水的可行性。According to the present applying situation, there exist some problems of water ed from top-cover of hydraulic turbines for use as technical water supply of units. Therefore the feasibility, economic benefits and matters needing attention of that the water draft from top-cover of medium-small-size hydraulic turbines for use as cooling water, water, discussed from follow- ing aspects: sealing rings gaps, the water quantity and pressure of water draft from top-cover, the layout of water draft tubes from top-cover and stabilization basin, operation mode and matters needing attention in the water draft from top-cover, etc.
