Abstract
The utility model relates to a lamp bulb through-flow unit operating oil tube multiple-support-point structure. A plurality of support points are arranged on an operating oil tube in a spindle, and support blocks are welded on the operating oil tube located at the positions of the support points. The plurality of support points are arranged on the operating oil tube in the spindle, and a distance between every two support points is small, so that the operating oil tube does not produce large deflection in the spindle, stress on the operating oil tube is not large, the oil tube can be ensured not to break, and a unit can stably operate for a long term.
Description
Technical field
The utility model belongs to the turbine equipment technical field, relates to the branched dot structure of a kind of bulb through-flow unit operating oil line, and it is applicable to the operating oil line structure in all bulb through-flow unit main shafts as an important component part in the Kaplan turbine assembling.
Background technique
Existing bulb through-flow water turbine, the operating oil line that the operation blade rotates generally only has two fulcrums in main shaft, and two fulcrums are the two ends at main shaft basically.When main axis length was very long, the distance between these two fulcrums will be very long.Because the rigidity of operating oil line is little, during unit operation, operating oil line is with the main shaft High Rotation Speed, and it can produce very large amount of deflection between two fulcrums in main shaft, produce very large additional alternation flexure stress at operating oil line simultaneously.The long term of these additional flexure stresses often causes the operating oil line fatigue fracture, has a strong impact on the normal operation of unit.
The model utility content
In order to overcome the above-mentioned shortcoming of prior art
,The utility model provides a kind of employing to add the structure of fulcrum in main shaft, shorten widely the distance between adjacent two fulcrums, can effectively avoid operating oil line in main shaft, to produce large amount of deflection and cause the branched dot structure of bulb through-flow unit operating oil line of operating oil line fracture.
The technological scheme that its technical problem that solves the utility model adopts is: the branched dot structure of a kind of bulb through-flow unit operating oil line, the operating oil line in main shaft is provided with some fulcrums, is welded with support block at the operating oil line that is positioned at the fulcrum place.
Described support block evenly distributes around the circumferencial direction of operating oil line.
Be welded with 6 support blocks on the operating oil line at each fulcrum place.
Distance between described adjacent fulcrum is consistent.
Outside weldings at every support block has bronze.
The thickness of described bronze is not less than 3.5mm.
The beneficial effects of the utility model are: the operating oil line in main shaft is provided with a plurality of fulcrums, between per two fulcrums apart from less, operating oil line just can not produce large amount of deflection in main shaft like this, stress on the operating oil line is little, can guarantee that operating oil line does not rupture, unit energy operation steady in a long-term.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is D-D sectional drawing among Fig. 1.
Among the figure: 1-main shaft, 2-operating oil line, 3-support block, 4-bronze.
Embodiment
Below in conjunction with drawings and Examples the utility model is further specified.
Referring to Fig. 1 and Fig. 2, the branched dot structure of a kind of bulb through-flow unit operating oil line, be provided with one or more fulcrums at main shaft 1 interior operating oil line 2,2 are welded with support block 3 on the operating oil line that is positioned at the fulcrum place, being welded with 3,6 support blocks 3 of 6 support blocks on the operating oil line 2 at each fulcrum place should be uniform around operating oil line 2 circumferencial directions.Friction ractor when reducing operating oil line 2 with respect to main shaft 1 move left and right between support block 3 and main shaft 1 endoporus spreads weldering bronze 4 in the outside of every support block 3, and bronze 4 thickness are not less than 3.5mm after guaranteeing processing excircles.Support block 3 spreads weldering bronze 4 rear processing excircles, and the total backlash of its outside diameter and inner hole of spindle diameter is controlled at 0.5mm～1.0mm, the deflection value that operating oil line 2 produces in the time of effectively controlling unit operation like this.
Because there is branched point in operating oil line in main shaft, between per two fulcrums apart from less, operating oil line just can not produce large amount of deflection in main shaft like this, the stress on the operating oil line is little, can guarantee that operating oil line does not rupture, unit energy operation steady in a long-term.
The utility model also can be generalized to relatively large and the unit that operating oil line is less of inner hole of spindle.For this type of unit, we can not be again with inner hole of spindle as the strong point, normally the correct position at inner hole of spindle adds a plurality of supports of burn-oning, and adds guide pad in the operating oil line relevant position.But the inner hole of spindle that has can not be crawled into the people and weld support, and at this moment we just only have the support at main shaft two ends is moved to the main shaft intermediate portion as far as possible.
