Abstract
The invention discloses a double-layer self-circulation oil-resistance plate. The double-layer self-circulation oil-resistance plate annularly sleeves an oil deflector and is composed of a bottom plate, a spacing plate and a top plate which are all on the same axis, the center of each of the bottom plate, the spacing plate and the top plate is provided with a through hole used for annularly sleeving the oil deflector, guide vanes are arranged between the bottom plate and the spacing plate to form a diversion cavity, a steady flow cavity is formed between the spacing plate and the top plate, the section of the spacing plate is concaved with the bottom provided with oil inlets, overflow holes are evenly formed in the wall of the spacing plate, the top plate covers the top end of the spacing plate, and the diameter of the top plate is larger than that of the spacing plate. By the arrangement, a loop capable of self-circulating is provided for rotary oil stream, so that the oil stream no longer splashes and bumps to be tossed out with rotation of a thrust collar or an end collar, and the problem about oil shedding at the position of the oil deflector of a bearing of a vertical hydro-generator unit is completely solved.
Description
Technical field
The present invention relates to a kind of seal arrangement, be specifically related to a kind of double-deck self-loopa oil-choking plate of the oil deflector place for vertical hydrogenerator bearing.
Background technique
The oil deflector place of current vertical hydrogenerator bearing often there will be gets rid of oily phenomenon, and the unit that size is larger, rotating speed is higher, occurs getting rid of oily probability larger.In order to stop, get rid of oily phenomenon, prior art often adopts the mode that multilayer oil-choking plate is installed, traditional oil-choking plate is plane ring flat-plate, after this oil-choking plate is installed, although can play the effect of oil resistance, because oil-choking plate is larger with large shaft clearance, cannot stop splashing of oil, still can there is the oil that gets rid of to a certain degree, affect the stable operation of hydraulic turbine generator unit.
Summary of the invention
Goal of the invention: the object of the invention is cannot stop splashing of oil in order to solve prior art oil-choking plate, still have the problem of getting rid of oily phenomenon to a certain degree, a kind of double-deck self-loopa oil-choking plate of the oil deflector place for vertical hydrogenerator bearing is provided.
Technological scheme: double-deck self-loopa oil-choking plate of the present invention, during use, outside by its ring set at oil deflector, by the base plate on same shaft axis, space bar and top board form, described base plate, the center of space bar and top board has the through hole for ring set oil deflector, between base plate and space bar, be provided with guide vane and form diversion cavity, between space bar and top board, form current stabilization chamber, the cross section of described space bar is spill, its bottom has oil inlet hole, on the wall of described space bar, evenly have overflow hole, described top board covers the top of space bar, the diameter of described top board is greater than the diameter of described space bar.
Further, described oil inlet hole is around the even circumferential arrangement of described through hole.Can make like this oil evenly from oil inlet hole, enter into current stabilization chamber.
Further, described top board cross section is inverted concave.When the oil overflowing of overflow hole is too much, can further prevent splashing of oil, also can play oily guide functions simultaneously.
When vertical hydrogenerator is worked, along with the rotation of thrust collar or axle neck, the oil outside oil deflector enters diversion cavity by guide vane, then by oil inlet hole, enters steady oil pocket, if it is less to enter the oil mass of steady oil pocket, oil can be stabilized in steady oil pocket; If oil mass is larger, oil can overflow along overflow hole, and the oil overflowing can also drop between space bar and base plate, by the effect of guide vane, oil is imported to diversion cavity again, has realized oily self-loopa process.Enter the oil of steady oil pocket after steady oil pocket, impact force declines, and can not cause and splash again.
Beneficial effect: double-deck self-loopa oil-choking plate of the present invention, for the oily stream of rotation provide one can self-loopa loop, thereby make it no longer along with the rotation of thrust collar or axle neck, splash, collide and throw away, thoroughly solved vertical hydrogenerator unit bearing oil deflector place and got rid of oily problem.

Embodiment
In order to deepen the understanding of the present invention, below in conjunction with embodiment and accompanying drawing, the invention will be further described, and this embodiment only, for explaining the present invention, does not form limiting the scope of the present invention.
Referring to Fig. 1-3, double-deck self-loopa oil-choking plate, during use, outside by its ring set at oil deflector, by the base plate 1 on same shaft axis, space bar 2 and top board 3 form, base plate 1, space bar 2 and top board 3 are cirque structure, base plate 1, the center of space bar 2 and top board 3 has the through hole for ring set oil deflector 7, between base plate 1 and space bar 2, be provided with guide vane 4 and form diversion cavity, the top of guide vane 4 is welded mutually and is evenly distributed on diversion cavity middle (as shown in Figure 3) with space bar 2 and base plate 1 respectively with bottom, between space bar 2 and top board 3, form current stabilization chamber, the cross section of space bar 2 is spill, its bottom has oil inlet hole 5, as shown in Figure 2, oil inlet hole 5 is around the even circumferential arrangement of described through hole, on the wall of space bar 2, evenly have overflow hole 6, the cross section of top board 3 is inverted concave, top board 3 covers the top of space bar 2, the diameter of top board 3 is greater than the diameter of space bar 2.
As shown in Figure 1, dotted arrow is the flow direction of oil stream, when vertical hydrogenerator is worked, rotation along with thrust collar or axle neck, oil outside oil deflector 7 enters diversion cavity by guide vane 6, then by oil inlet hole 5, enter steady oil pocket, if it is less to enter the oil mass of steady oil pocket, oil can be stabilized in steady oil pocket; If oil mass is larger, oil can overflow along overflow hole 6, and the oil overflowing can also drop between space bar 2 and base plate 1, by the effect of guide vane 6, oil is imported to diversion cavity again, has realized oily self-loopa process.
The foregoing is only preferred embodiment of the present invention, in order to limit the present invention, within the spirit and principles in the present invention not all, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection scope of the present invention.
