GUIDE APPARATUS FOR TURBOMACHINES |
摘要 |
The invention relates to a guide apparatus for turbomachines, in particular for Francis or Kaplan turbines or pumps or pump turbines having a plurality of guide blades which can be actuated via in each case one link on a common adjusting member. Here, every guide blade or every second guide blade can be equipped with a bending element. A bending-failure link can have a screw connection and a bending body element. The screw connection is prestressed and is configured with a defined fracture cross section. The triggering force on the bending-failure link and the holding force after a fracture of the bending element can therefore be selected independently of one another. The guide blades are protected against damage by foreign bodies in the guide apparatus. |
