Description
Technical field
The present invention relates to sleeve technology field, specially a kind of wear sleeve.
Background technology
At present, conventional inner sleeve exists more and worn no resistance, and easily wears, and service life is low, changes frequent, replacing liner plate
Tedious process, the problems such as having a strong impact on production, therefore, need badly and inner sleeve is improved.
The content of the invention
It is an object of the invention to provide a kind of wear sleeve, to solve the problems mentioned in the above background technology.
To achieve the above object, the present invention provides following technical scheme：A kind of wear sleeve, including cylinder, the cylinder
For cylindrical structure, multiple wear-resistant sleeves are bonded on the cylinder body outer wall from top to bottom, composite compression-resisting layer on the wear-resistant sleeve outer wall,
The upper and lower end of the cylinder body outer wall is provided with neck, is connected with stirrup ring in the neck, on the cylinder inboard wall
It is coated with nanocrystalline alloy coating.
Preferably, the wear-resistant sleeve uses ceramic jacket, and the ceramic jacket is bonded cylinder body outer wall by ceramic abrasionproof adhesive.
Preferably, the resistance to compression layer uses 17CrNiMo carbon steel materials.
Preferably, the nanocrystalline alloy coating uses Ti-48Al-8Cr-2Ag nanocrystalline coatings.
Preferably, the thickness of the wear-resistant sleeve is 2mm-4mm.
Compared with prior art, the beneficial effects of the invention are as follows：
（1）The present invention is simple in construction, wherein, it is bonded multiple wear-resistant sleeves on cylinder body outer wall from top to bottom, it is compound on wear-resistant sleeve outer wall
Resistance to compression layer, wear-resistant sleeve use ceramic jacket, and ceramic jacket is bonded cylinder body outer wall by ceramic abrasionproof adhesive, and the ceramic jacket of bonding can
The effective abrasion for preventing sleeve outer wall, in addition, ceramic jacket possesses excellent anti-wear performance in itself, it is compound on wear-resistant sleeve outer wall
17CrNiMo carbon steel material resistance to compression layers, additionally it is possible to play a part of protect wear-resistant sleeve, further extend sleeve use the longevity
Life.
（2）In the present invention, the upper and lower end of cylinder body outer wall is provided with neck, and stirrup ring is connected with neck, is adopted
With this structure, the cracking phenomenon of sleeve both ends nozzle can be effectively prevented.
（3）Ti-48Al-8Cr-2Ag nanocrystalline coatings are coated with the present invention, on cylinder inboard wall, can be effectively protected
Cylinder inboard wall, corrosion, wear phenomenon is prevented, and then extend sleeve service life.
