Abstract
The utility model discloses a novel wear-resistant plate bottom ring structure. The laser cladding layer is metallurgically bonded with the bottom ring. The laser cladding layer has an abrasion-resistant function, replaces a bottom ring which is assembled with an abrasion-resistant plate in the traditional design, and enables the bottom ring body to have the abrasion-resistant function; the utility model can effectively reduce the processing and installation procedures of the wear plate in the traditional design; effectively reduce the building site end ring, wear plate installation period, the utility model discloses the site maintenance of being convenient for reduces the accident potential, improves unit operation precision.
Description
The technical field is as follows:
the utility model relates to a novel wear plate bottom ring structure can be used to among the hydraulic turbine unit, replaces the bottom ring that traditional design was equipped with the wear plate.
Background art:
the hydraulic turbine set is characterized in that a wear-resistant plate is additionally arranged on the bottom ring in order to improve the abrasion resistance of the bottom ring, but the hydraulic turbine set is subjected to vibration and impact damage in the operation process, the wear-resistant plate adopted in the existing hydraulic turbine set is installed by a bolt handle, and the bolt is loosened and broken frequently under the action of vibration and impact damage to cause accidents. In order to install the wear plate, centimeter-level deep processing needs to be carried out on the bottom ring, and the bottom ring can be subjected to stress release deformation in the processing process. The wear plate is the unit in aspects such as processing, building site installation, calibration increase processing cost and installation cost, increase unit accident hidden danger. Along with the progress of the laser cladding technology, a laser cladding layer which is metallurgically combined with a matrix, has high strength, wear resistance and corrosion resistance and has no deformation influence on the matrix is formed on the surface of the metal, the wear-resistant plate with the traditional design is replaced by the laser cladding layer, the destructive influence on the bottom ring is small, the processing and the installation are convenient, the bottom ring and the laser cladding layer are metallurgically combined into a whole, the installation is simple and convenient, the installation links are reduced, and the installation precision of a unit is improved.
The invention content is as follows:
in order to reduce the installation link, improve the unit and wear and corrosion resistance, improve the installation accuracy, eliminate unit accident hidden danger, the utility model provides a novel wear-resisting plate bottom ring structure, technical scheme is: forming a laser cladding layer on the upper surface of the bottom ring in a laser cladding mode; the upper surface of the bottom ring is metallurgically bonded with the laser cladding layer; except the circumferential array shaft holes on the upper surface of the bottom ring, the whole surface of the bottom ring forms a laser cladding layer in a laser cladding mode, and the bottom ring and the laser cladding layer are of an integrated structure.
The technical effects are as follows:
the utility model relates to a novel wear-resistant plate bottom ring structure is one kind at the bottom ring upper surface, the position that is equipped with wear-resistant plate in traditional design, the method that adopts laser cladding forms one deck and the metallurgical combination of bottom ring, high strength and wear-resisting corrosion resisting property have, the laser cladding layer to the influence of bottom ring nothing deformation, replace the wear-resistant plate of traditional design assembly with laser cladding layer, it is little to have the destructive influence to the bottom ring, processing, simple to operate's characteristics, bottom ring becomes an organic whole with laser cladding layer, reduce the installation link, the unit installation accuracy has been improved.
Description of the drawings:
fig. 1 is a schematic structural section of the present invention.
Fig. 2 is a schematic top view of the structure of the present invention.
The specific implementation mode is as follows:
the invention is further described with reference to the accompanying drawings and the detailed description.
As shown in fig. 1 and 2, a novel wear plate bottom ring structure comprises a bottom ring 1, a laser cladding layer 2 and a circumferential array shaft hole 3.
As shown in fig. 1, after the upper surface of a bottom ring 1 is processed to be flat, a laser cladding layer 2 is formed by adopting a laser cladding technology;
as shown in FIG. 2, a laser cladding layer 2 is clad on the upper surface of the bottom ring 1 except for the circumferential array shaft holes 3.
As shown in fig. 1, the laser cladding layer 2 is metallurgically bonded to the bottom ring 1;
as shown in fig. 1, the laser cladding layer 2 is processed to a suitable degree of surface roughness.
When the wear-resistant plate is used, the laser cladding layer 2 replaces a wear-resistant plate of a traditional design, the bottom ring 1 and the laser cladding layer 2 are metallurgically combined into a whole, and the guide vane shaft is arranged in the circumferential array shaft hole 3.
The foregoing has outlined rather broadly the principles and features of the present invention in connection with the accompanying drawings. It should be understood by those skilled in the art that the above embodiments do not limit the present invention in any way, and all technical solutions obtained by adopting equivalent replacement or equivalent transformation fall within the protection scope of the present invention.
