Abstract
The utility model discloses a kind of zirconia ceramics split coupling, comprise sleeve body, described sleeve body is hollow cylindrical, the top of described sleeve body is provided with an opening, be provided with some raised lines to axle center projection inside described sleeve body, described some raised lines take axle center as the center of circle, and uniform circular distributes, the two opposite sides of described sleeve body are provided with mounting knob, and described sleeve body is ceramic body.Zirconia ceramics split coupling of the present utility model is provided with opening, facilitate tea to have a rest and change, the raised line inside it can increase fixing stability, and the utility model structure is simple, long service life, increases greatly than traditional sleeve pipe decay resistance and abrasion resistance properties.
Description
Technical field
The utility model relates to a kind of sleeve pipe, particularly a kind of zirconia ceramics split coupling.
Background technique
Sleeve pipe, is used in building basement usually, is used for protective conduit or facilitate the iron ring of Pipe installing.Slurry pump is the heart of oil drilling system, be responsible for slurry transportation to down-hole, complete the transmission of matter and energy, and cylinder sleeve is the easy-abrasion part of slurry pump, along with the mankind are to the continuous expansion of the limit of mining of Global Oil and Gas Resources, and more and more severe, a large amount of Metallic cylinders is changed the requirement being all difficult to ensure rig high pressure and wearing and tearing frequently.
Summary of the invention
In order to overcome above-mentioned defect, the utility model provides one and can solve the problem, wear-resistant, and stability is strong, zirconia ceramics split coupling easy to use.
The utility model in order to the technological scheme solving its technical problem and adopt is: a kind of zirconia ceramics split coupling, comprise sleeve body, described sleeve body is hollow cylindrical, the top of described sleeve body is provided with an opening, be provided with some raised lines to axle center projection inside described sleeve body, described some raised lines take axle center as the center of circle, and uniform circular distributes, the two opposite sides of described sleeve body are provided with mounting knob, and described sleeve body is ceramic body.
As further improvement of the utility model, be provided with three raised lines inside described sleeve body, described raised line distributes with sleeve body inside circumference uniform intervals.
As further improvement of the utility model, described sleeve body is by being oxidized white pottery and alumina powder is made.
The beneficial effects of the utility model are: zirconia ceramics split coupling of the present utility model is provided with opening, facilitate tea to have a rest and change, raised line inside it can increase fixing stability, the utility model structure is simple, long service life, increases greatly than traditional sleeve pipe decay resistance and abrasion resistance properties.
