Description
Technical field
The utility model belongs to steam turbine technology field; Relate to a kind of Turbine seal formula oil catch specifically.
Background technique
Steam turbine is domestic production and the requisite power plant of generating, steam turbine is after the running of several years, usually there will be unit strenuous vibration, gland sealing gear also there will be wearing and tearing in various degree, labyrinth clearance is caused to expand gradually, cause leaking of steam, great potential safety hazard is brought to the normal operation of steam turbine, present millworker is generally by changing gland blocks, the method of adjustment labyrinth clearance solves this problem, but this settling mode not only labor strength is large, and engineering time is long, directly affects the normal use of steam turbine, manufacturing efficiency is low.
Summary of the invention
Goal of the invention of the present utility model:
Mainly there is potential safety hazard to solve traditional Turbine seal, manufacturing efficiency is low, the technical problem that labor strength is large.
The technical solution of the utility model is:
Provide a kind of Turbine seal formula oil catch, comprise flinger ring and seal oil chamber, seal oil chamber is arranged on the inner side of flinger ring, oil-return groove is offered in the bottom in seal oil chamber, the right side in seal oil chamber is provided with a sealed air chamber, in sealed air chamber, bottom is directly wanted to be communicated with nitrogen delivery pipe, and the left and right sides above sealed air chamber is respectively arranged with floating seal ring one and floating seal ring two.
The beneficial effects of the utility model are:
Effectively raise the sealingly secure of steam turbine, improve the manufacturing efficiency of enterprise, reduce the labor intensity of workman.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
In figure; 1 is flinger ring; 2 is oil-return groove; 3 is sealed air chamber; 4 is nitrogen delivery pipe; 5 is floating seal ring one; 6 is floating seal ring two; 7 is seal oil chamber.
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described in detail.
As shown in Figure 1, provide a kind of Turbine seal formula oil catch, comprise flinger ring 1 and seal oil chamber 7, seal oil chamber 7 is arranged on the inner side of flinger ring 1, oil-return groove 2 is offered in the bottom in seal oil chamber 7, a sealed air chamber 3 is provided with on the right side in seal oil chamber, in sealed air chamber, bottom is directly wanted to be communicated with nitrogen delivery pipe 4, the left and right sides above sealed air chamber is respectively arranged with floating seal ring 1 and floating seal ring 26, the utility model structure is simple, hermetic unit is made up of seal oil and nitrogen-sealed two-part, better can complete the backflow of lubricant oil and the leakage of water vapour, avoid steam and enter lubricating oil system and the outside leakage problem of steam turbine sealing gland by oil catch.
