Abstract
The invention discloses a water turbine guide vane shear pin annunciator testing appliance which is composed of a support, a shear pin die and a hydraulic jack. The shear pin die is composed of an upper model block and a lower model block, wherein the model blocks are provided with central holes. The central holes of the upper model block and the lower model block are mutually communicated and used for arranging a shear pin annunciator. The lower model block and the hydraulic jack thereof are installed in a sliding groove of the support to form into a sliding fit. A expansion link of the hydraulic jack is arranged against the outer side wall of the lower model block and vertical to the central hole thereof. The upper model block is fixed on the support. The water turbine guide vane shear pin annunciator testing appliance is simple in structure, convenient to operate, safe, reliable and capable of reflecting motion conditions of the annunciator well.
Description
Technical field
The invention belongs to the test tool technical field, specifically a kind of turbine generator guide vane break pin signalling means test tool.
Background technology
The at present field test for stator break pin signalling means there is no effective method, the method that common use directly fractures, but result and actual conditions have very large error, the action situation of signalling means in the time of can not reflecting real work.
Summary of the invention
Technical matters to be solved by this invention provides a kind of guide vanes of water turbine break pin signalling means test tool, can simulate the fracture working condition of signalling means behind the break pin of guide vanes of water turbine fault, reflects the actual act situation of signalling means.
The present invention addresses the above problem with following technical scheme:
Guide vanes of water turbine break pin signalling means test tool of the present invention, it is comprised of support, break pin mould, hydraulic jack, described break pin mould is made of two model block that have center pit up and down, the center pit of two model block communicates and is used for placing the break pin signalling means up and down, wherein drag piece and hydraulic jack are installed in to form in the chute of support and are slidingly matched, and the expansion link of hydraulic jack withstands on the lateral wall of drag piece and be perpendicular with its center pit; Upper model block is fixed on the support.
Guide vanes of water turbine break pin signalling means test tool of the present invention, described up and down two model block are two hollow cylinders.
Utensil of the present invention has following advantage:
1, simple in structure, easy to operate, safe and reliable.
2, because the effect of the chute on the support, the drag piece of placing the break pin signalling means only has mobile stably forward, and can not swing, the shearing force that forms with upper model block and the actual stator shearing force that break pin cuts off that is in operation is basically identical, therefore good reflected signal device action situation.
Description of drawings
Fig. 1 is the structural representation of guide vanes of water turbine break pin signalling means test tool of the present invention.
Among the figure: 1-support, 2-upper model block, 3-drag piece, 4-hydraulic jack.
Embodiment
As shown in Figure 1, utensil of the present invention is comprised of support 1, break pin mould and hydraulic jack 4, upper model block 2 and drag piece 3 that the break pin mould is touched by close proximity consist of, upper model block 2 and drag piece 3 all have center pit, and two center pits communicate and be used for placing the break pin signalling means, wherein drag piece 3 and hydraulic jack 4 are installed in to form in the chute of support 1 and are slidingly matched, and the expansion link of hydraulic jack 4 withstands on the lateral wall of drag piece 3 and be perpendicular with its center pit; Upper model block 2 is weldingly fixed on the upper end of support 1.
When carrying out experiment work, the break pin signalling means is put into the center pit of break pin mould, with the break-make situation of multimeter supervisory signal device.Manual operation hydraulic jack 4 during test, drag piece 3 is moved forward, the linking part of upper model block 2 and drag piece 3 forms shearing motion, cut off signalling means, check the break-make situation of signal, thereby under realizing that utensil of the present invention can the analog operation state, guarantee correctness and the reliability of signalling means action.
Upper model block 2 of the present invention and drag piece 3 all can adopt hollow cylinder, also can adopt other shape.
Claims (2)
1. guide vanes of water turbine break pin signalling means test tool, it is characterized in that, this utensil is comprised of support, break pin mould, hydraulic jack, described break pin mould is made of two model block that have center pit up and down, the center pit of two model block communicates and is used for placing the break pin signalling means up and down, wherein drag piece and hydraulic jack are installed in to form in the chute of support and are slidingly matched, and the expansion link of hydraulic jack withstands on the lateral wall of drag piece and be perpendicular with its center pit; Upper model block is fixed on the support.
