Abstract
The utility model relates to a composite material runner blade for an axial flow hydraulic turbine. A metal framework is arranged in the runner blade body for the axial flow hydraulic turbine and is fixed to the shaft head of the blade; a composite material filling body is arranged on the outer side of the metal framework; and a skin is covered on the outer side of the composite material filling body. According to the composite material runner blade, the characteristics of anti-fatigue performance of the special composite material and the high stiffness of the metal framework are effectively used, and the runner blade for the axial flow hydraulic turbine can bear fatigue damage and hydraulic load caused by cyclic stress.
Description
Technical field: the utility model relates to a kind of axial flow hydraulic turbine composite material runner bucket.
Background technique: blades for axial-flow water turbine is the critical piece that bears hydraulic load, evenly arranges, when bearing very big Hydraulic Moment, receives small fluctuating load again, can cause blade local location generation fatigue damage, crackle occur.The form that interior metal skeleton bonded composite is filled can be utilized the heavily stressed intensity of composite material, the characteristics of high-fatigue strength; Make turbine runner blade avoid occurring crackle; Simultaneously can utilize the high characteristics of metal frame rigidity again, bear hydraulic load, moderate finite deformation can not take place.
Summary of the invention: the purpose of the utility model provides a kind of design concept of effective and feasible blades for axial-flow water turbine, achieves the goal through adopting metal frame form filled composite materials form.The technological scheme of the utility model is: a kind of axial flow hydraulic turbine composite material runner bucket; In the runner blade lamellar body of axial flow hydraulic turbine is metal frame; Metal frame is fixed on the blade spindle nose, and metal frame is outside fills body for composite material, and composite material is filled external parcel covering.The utility model metal frame structure can provide enough rigidity to bear hydraulic load, simultaneously, can utilize the shop layer design of the uniqueness of composite material again, reaches good fatigue behaviour, thus the runner bucket fatigue damage of avoiding water flow disturbance to cause.
Description of drawings:
Fig. 1 axial flow hydraulic turbine composite material runner bucket
Fig. 2 kaplan turbine runner blade metal frame
Embodiment:
The utility model as shown in Figure 1 is a kind of axial flow hydraulic turbine composite material runner bucket; In the runner blade lamellar body of axial flow hydraulic turbine is metal frame 3; Metal frame 3 is fixed on the blade spindle nose 2, and metal frame is outside fills body for composite material, and composite material is filled external parcel covering 1.
The utility model skin is avoided runner bucket to cause fatigue damage because of receiving fluctuating load, thereby is guaranteed the fatigue life of whole runner bucket with the good composite material parcel of fatigue characteristic; Simultaneously, the metal frame structure can provide enough rigidity to bear hydraulic load, big deformation can not take place; And, utilize the good characteristics of composite material workability, can process more approaching theoretical runner bucket, thereby guarantee turbine efficiency.
