Abstract
The utility model relates to an improved device of an oil baffle plate of an upper frame of a vertical machine set, in particular to a device for preventing oil mist from overflowing from a gap between a thrust head and a sealing cover plate of the upper frame when a small and medium sized vertical hydraulic generator is operated. The added oil baffle plate is arranged on the sealing cover plate with a labyrinth seal structure and is filled up with oil resistant rubber, and when the oil baffle plate is assembled or disassembled, only bolts on the oil baffle plate need to be assembled and disassembled. The oil mist overflowing from the sealing cover plate enters the oil baffle plate, and because the space is increased suddenly, the pressure is reduced, and the possibility that the oil mist overflows from the gap between the thrust head and the oil baffle plate again is greatly reduced. In addition, improvement is carried out on the sealing cover plate which is drilled with oblique oil return holes. The utility model has the advantages of simple structure, low cost, convenient maintenance and installation and good operation effect.
Description
Technical field
The utility model relates to a kind of vertical unit upper spider oil baffle modifying device, is meant middle-size and small-size vertical hydrogenerator especially in the running, prevents the device that overflows the space of mist of oil between upper spider thrust collar and sealed cover.
Background technique
At present, the oil seal of thrust-bearing is not very tight, not only will consume lubricant oil more, and will pollute winding, damages insulation, influences unit safety operation, and wherein important reason is exactly to overflow the space of oil between upper spider thrust collar and sealed cover.
Summary of the invention
The purpose of this utility model is: overflows in order to prevent mist of oil, on former seal arrangement, improves, increased oil baffle, and oil resistant rubber, and on sealed cover, increase spill port, in order to balance pressure.
The technical solution of the utility model is achieved in that it is installed in the top of upper spider, and thrust collar is installed between generator shaft and the guide bearing, links with runner plate; Oil baffle is entered from the thrust collar cover, is contained on the sealed cover; Fill up oil resistant rubber between oil baffle and the sealed cover, fastening with bolt and sealed cover; On sealed cover, be drilled with spill port.Oil baffle is mounted on the sealed cover of band labyrinth seal structure, and the bolt that the mounting or dismounting oil baffle need only be installed and removed on the oil baffle gets final product; During running, the mist of oil that overflows from sealed cover enters oil baffle, because the space increases suddenly, pressure reduces, and greatly reduces the possibility of overflowing from the space of thrust collar and oil baffle once more; Fill up oil resistant rubber between oil baffle and the sealed cover, oil sealing can be lived, outwards do not overflow; In addition former sealed cover is improved, be drilled with the spill port of inclination, the oil that can will be spilled over to the oil baffle inner chamber flows back in the thrust-bearing oil pocket.
The utility model has the advantages that: can prevent from effectively to overflow the space of mist of oil between upper spider thrust collar and sealed cover, and the long-pending oil that will be spilled over to the oil baffle inner chamber flows back in the thrust-bearing oil pocket.Preventing to pollute winding, damage insulation, thereby prolong unit working life.

Embodiment
The utility model is achieved in that it is installed in the top of upper spider 9.Thrust collar 5 is installed between generator shaft 6 and the guide bearing 7, links with runner plate 8; Oil baffle 2 is entered from thrust collar 5 covers, is contained on the sealed cover 4; Pad oil resistant rubber 3 is fastening with bolt 1 and sealed cover 4 between oil baffle 2 and the sealed cover 4; On sealed cover 4, be drilled with spill port 10.
Middle-size and small-size vertical hydrogenerator in the running, mist of oil can overflow from the space between upper spider thrust collar and the sealed cover.In order to prevent that better mist of oil from overflowing, on former seal arrangement, improve, increased oil baffle 2, oil resistant rubber 3, and on sealed cover 4, increase by 6 spill ports 10, but and balance pressure.Oil baffle 2 is installed on the sealed cover 4 of band labyrinth seal structure, is fixed on the sealed cover 4 with bolt 1, and pad oil resistant rubber 3 between oil baffle 2 and the sealed cover 4 can prevent after tightening that oil from overflowing between oil baffle 2 and sealed cover 4; After the mist of oil that overflows from sealed cover 4 entered oil baffle 2 in addition, because the space increases suddenly, pressure reduced, and greatly reduces the possibility of overflowing from the space of thrust collar and oil baffle once more; The spill port 10 that increases on the sealed cover 4, the long-pending oil of oil baffle 2 inner chambers is back in the thrust-bearing oil pocket, and all right balance pressure of spill port has prevented that better mist of oil from overflowing, and pollutes winding, damages insulation.
