Combined and multi-task water turbine runner on-site processing factory design method

Abstract

The invention relates to a combined and multi-task water turbine runner on-site processing factory design method which is characterized in that only one runner on-site processing factory is arranged to simultaneously meet the on-site processing progress of two or more different runners and two types of multiple sets of large and heavy parts, that is, only one on-site runner processing factory needs to be arranged; and through the design of machining stations, working procedures, equipment configuration and ancillary facilities of large and heavy parts, different runners can be machined in a combined mode, machining of a plurality of runners and a lower rack center body can be achieved at the same time in a multi-task mode, and the problem that a plurality of on-site processing factories need to be arranged is solved. Besides, the combined and multi-task runner on-site processing factory can share one processing factory, and also can share a bridge crane, a processing station with low utilization rate and ancillary facilities such as a transformation power distribution room, a compressed air room, an office rest room, a tool room, a temporary storage room, a toilet and the like, so that the engineering investment is greatly saved.

Description

technical field [0001] The invention relates to the technical field of water conservancy and hydropower, in particular to a combined and multi-task design method for workstations, auxiliary equipment and facilities of on-site processing plants for hydraulic turbine runners. Background technique [0002] Along with the development of hydropower resources in western my country, large and extra-large hydropower stations have been launched one after another. Most of these power stations are located in high mountains and valleys, and transportation is difficult. The key components of large hydropower units are the turbine runner and the central body of the lower frame of the generator. Transportation is especially difficult because of overweight and oversized items. The overall runner or the central body of the lower frame cannot be directly transported by railway, highway or waterway, and the overall transportation risk is high and the cost is high, making it a bottleneck restric...

Problems solved by technology

However, due to the tight construction site and limited conditions, the on-site processing plant for heavy parts needs to be considered as a whole

Especially when the number of units is large and there are many suppliers of unit manufacturers, it is necessary to coordinate different process plans of each factory, cross delivery schedules, different supporting requirements, and meet the installation schedule of the two major parts of the runner and the lower frame at the same time. The work, especially the heavy parts of the unit, has complex processing procedures and high processing accuracy requirements. It is usually necessary to set up multiple runner processing factories on site. However, multiple runner processing factories are not only difficult to arrange and design due to geological and terrain conditions, but also greatly increase the number of runners. upfront investment
