Abstract
The plate main shaft sealing device of a kind of vertical turbine comprises some black boies, black box comprises fixed support and silica gel piece, be connected with silica gel piece on the downside of fixed support, have gap on the downside of fixed support one end and between silica gel piece, silica gel piece is provided with some through holes and this through hole is uniformly distributed in below silica gel piece and fixed support junction surface.The beneficial effects of the utility model are: some black boies vertically arrange and are interconnected, black box comprises fixed support and silica gel piece, be connected with silica gel piece on the downside of fixed support, gap is had on the downside of fixed support one end and between silica gel piece, during main axis, hydraulic pressure upwards, makes to fit tightly on the downside of silica gel piece and fixed support, makes the press water sealing effect of the plate main shaft sealing device of vertical turbine better; Silica gel piece is provided with some through holes and this through hole is uniformly distributed in below silica gel piece and fixed support junction surface, reduces the wearing and tearing between silica gel piece and fixed support, increases the working life of seal arrangement.
Description
Technical field
The utility model relates to the plate main shaft sealing device of a kind of vertical turbine, particularly relates to a kind of plate main shaft sealing device of vertical turbine of high-rating generator part field.
Background technique
Main shaft sealing device is one of vitals of water turbine, but radially wobbling due to the main shaft relative casing of on-stream existence, make main shaft sealing device fail so far to survey the seepy question that the end solves press water.
Summary of the invention
The utility model is intended to invent a kind of good sealing effect and the plate main shaft sealing device of the vertical turbine of long service life.
The plate main shaft sealing device of a kind of vertical turbine comprises some black boies, described some black boies vertically arrange and are interconnected, described black box comprises fixed support and silica gel piece, be connected with silica gel piece on the downside of fixed support, have gap on the downside of fixed support one end and between silica gel piece, described silica gel piece is provided with some through holes and this through hole is uniformly distributed in below silica gel piece and fixed support junction surface.
Preferably, described fixed support length is 200-300mm, is highly 150-200mm.
Preferably, described silica gel piece length is 400-600mm, and thickness is 100-120mm.
Preferably, the clearance height on the downside of described fixed support one end and between silica gel piece is 30-50mm.
Preferably, described some black boies are connected by bayonet lock.
The beneficial effects of the utility model are:
1. some black boies vertically arrange and are interconnected, black box comprises fixed support and silica gel piece, be connected with silica gel piece on the downside of fixed support, gap is had on the downside of fixed support one end and between silica gel piece, fixed support length is 200-300mm, be highly 150-200mm, silica gel piece length is 400-600mm, thickness is 100-120mm, clearance height on the downside of fixed support one end and between silica gel piece is 30-50mm, during main axis, hydraulic pressure upwards, make to fit tightly on the downside of silica gel piece and fixed support, make the press water sealing effect of the plate main shaft sealing device of vertical turbine better,
2. silica gel piece is provided with some through holes and this through hole is uniformly distributed in below silica gel piece and fixed support junction surface, reduces the wearing and tearing between silica gel piece and fixed support, increases the working life of seal arrangement.
