A new type of plate pump type oil retaining cylinder oil retaining structure for vertical hydro-generator

Abstract

The invention discloses a novel plate pump type oil blocking barrel oil blocking structure of a vertical hydraulic generator. The oil blocking structure comprises a thrust block, a ring, an oil blocking barrel and an upper rack, and is characterized in that the oil blocking barrel is arranged on the upper rack, and the oil blocking barrel and the upper rack are mutually and fixedly welded; the ring is arranged on one side of the oil blocking barrel, the ring and the oil blocking barrel are mutually and fixedly welded, and the ring is flush with a pilot bearing bush central line; a circle of holes are evenly formed in the thrust block at the height of a guide shoe central line. According to the novel plate pump type oil blocking barrel oil blocking structure, the circle of holes are formed in the thrust block at the height of the guide shoe central line, the thrust block plays a role of a pump when rotating, and with blocking of the ring, oil can difficultly climb; even if a little oil climbs, the upper oil blocking barrel plays the role of double-layer oil blocking pipes, and leakage of the oil is completely prevented; the oil leakage problem of bearings of the upper rack of the vertical hydraulic generator is solved, and the oil blocking structure has the advantages of being good in oil blocking effect, simple, and easy to machine.

Description

technical field [0001] The invention relates to the field of auxiliary equipment for vertical hydroelectric generators, in particular to a novel plate pump type oil retaining cylinder oil retaining structure for vertical hydroelectric generators. Background technique [0002] At present, when the vertical hydro-generator is running fast, the oil in the oil tank of the upper frame will constantly surge and roll, and the oil pressure will also increase, along the thrust head, and then overflow from the oil retaining tube, especially The unit with relatively high speed not only consumes more lubricating oil, but also pollutes the winding, damages the insulation, affects the safe operation of the unit, and may burn out the thrust bush and guide bush due to too little oil after oil leakage, among which the most important The reason is that the more important reason is that the oil retainer is not very ideal in structure, so the oil retainer must be improved to prevent the oil in ...

AI Technical Summary

Problems solved by technology

In this way, the whole structure completely solves the oil leakage problem of the upper frame bearing of the vertical hydro-generator, and it also has the function of the upper ring of the oil retaining tube, which prevents the overflow of oil well, and the upper part of the oil retaining tube ring and the thrust head Appropriate distance design, with the function of double-layer oil retaining cylinder
