Design And Engineering Case Of Hydraulic Power Station Work Shop On Light Bulb Stubular Turbines

Presently, the construction of water resources and hydroelectric projects is being in the unprecedented vigorous development time in china. Many low-height of water and runoff type hydroelectric power stations are being constructed gradually, and the hydroelectric power stations are made up of the bulbs tubular turbine have been a excellent development pattern at a present time, because they possess a lot of merits such as the smooth channel, the big loading capacity, the high speed of rotation, the high efficiency, the small size, the light weight, the energy and the economic index are good and so on. However, Because the powerhouse of the bulbs hydroelectric power stations are made up of tubular turbine have the unique arrangement pattern, which reflects on the characteristic that the stress distribution is different from the conventional hydroelectric power station powerhouse. Therefore, the research and analysis about the station is the extremely important practical significance.Since 1990s, there are over 10 big and small the hydroelectric power stations are made up of the bulbs tubular turbine have been designed early or late by The Pearl River committee designing institute within the boundaries of Guangdong's Beijiang River, Dong Jiang, Mei Jiang and so on, and the designing institute has turned into the main army of the hydroelectric power station designed. The article is writtenin the foundation that completely succeed and develop our designing institute's design achievement in the powerhouse of the hydroelectric power stations are made up of tubular turbine, at the same time I combines the question that the students meet in the powerhouse technique which in the design and the construction in the honghua hydroelectric power station, and we carry on the analysis argumentation and design research. The main research content includes:First. The design of the powerhouse of the hydroelectric power stations are made up of the light bulbs tubular turbine;Refers to domestic arrangement experience which other powerhouse of the hydroelectric power stations are made up of the bulbs tubular turbine had been completely constructed, and systematically introduces conventional design mentality of powerhouse of the hydroelectric power stations are made up of the bulbs tubular turbine, includes key position arrangement, factory district arrangement, powerhouse arrangement and so on.Second. The main experience of powerhouse structural design of the hydroelectric power stations are made up of the bulbs tubular turbine;Circumfuse this question how to carry on he powerhouse structural design combining the actual situation of hydroelectric power station and the unit characteristic. In powerhouse structural design, some frequentlyasked questions, the difficult question and other worth noting question, I thoroughly discusses one by one.Third. Key position arrangement and powerhouse design in honghua hydroelectric power station;Introduces the project survey of the Liujiang safflower hydroelectric power station, the key position arrangement collectively. Discusses the elaboration honghua factory district, the characteristic of powerhouse arrangement. And researches and analysises some questions optimized processes in the design process. And carries on the whole stable analysis and the finite element analysis to the powerhouse structure.Fourth. Several key questions and solution measure in design;Contraposing the views of the technique in the design, honghua hydroelectric power station have several unique key design questions for example: the corresponding stress influence about detaching seam and water tightness, the processing of powerhouse groundwork, the tailwater and pillar wall structural design, the factory district slope design and so on. I carries through analysis and research one by one, contrasts proposed many solution, selects the most superior scheme and proposes the reasonable project measures.
