Abstract
The utility model relates to a centralizer, especially a high -efficient wear -resisting centralizer, including being columniform centralizer body, centralizer body surface is provided with the centralizer arris body, centralizer arris body surface face spiral spaced distributes there are a plurality of recesses, be provided with wear -resisting piece in the recess, gap between the wear -resisting piece forms the chip groove. Centralizer body both ends are provided with respectively and connect and connect the hole, wear -resisting piece is the welding with the connected mode of recess, centralizer arris body hardness >= HRC33, wear -resisting piece hardness >= HRC50. The beneficial effects of the utility model are that: 1, manufacturing is simple, and the precision is unified, and manufacturing cost reduces, 2, utilize wear -resisting piece and external contact, further increase of service life, 3, utilize the recess between the wear -resisting piece to form the chip groove to do benefit to the heat dissipation more.
Description
Technical field
This utility model is a kind of centralizer, particularly a kind of high-efficiency abrasion-proof centralizer.
Background technology
At present, centralizer is widely used in mining industry, in petroleum industry, plays and puts tiltedly effect, after using a period of time, righting
Device is worn and can not use, and service life is short, and general hard alloy is low with centralizer bond strength, holds when its work
Easy to fall off, reduce its service life further.Therefore, invent longer centralizer in a kind of service life to be particularly important.
Utility model content
This utility model is adopted the technical scheme that to solve above-mentioned technical problem:
High-efficiency abrasion-proof centralizer, including in cylindrical centralizer body, described centralizer body surface configuration has righting
Device rib body, described centralizer rib surface spiral spacer some groove is distributed, be provided with wear-resistant block in described groove, described
Slit-shaped between wear-resistant block becomes chip area.
Further, described centralizer body two ends are respectively arranged with joint and connect hole.
Further, described wear-resistant block with the connected mode of groove for welding.
Further, described centralizer rib body hardness >=HRC33, described wear-resistant block hardness >=HRC50.
To sum up, the beneficial effects of the utility model are:
1, processing and manufacturing is simple, and precision is unified, and manufacturing cost reduces；
2, utilize wear-resistant block and external contact, increase the service life further；
3, utilize the groove type between wear-resistant block to become chip area, and be more favorable for heat radiation.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model；
Fig. 2 is channel section schematic diagram of the present utility model.
Wherein, 1-centralizer body, 2-centralizer rib body, 3-groove, 4-wear-resistant block, 5-chip area, 6-joint, 7-connect
Hole.
Detailed description of the invention
As illustrated in fig. 1 and 2, high-efficiency abrasion-proof centralizer, including in cylindrical centralizer body 1, described centralizer body 1
Surface configuration has centralizer rib body 2, and what described centralizer rib body 2 perficial helical was spaced is distributed some grooves 3, described groove 3
Inside being provided with wear-resistant block 4, the slit-shaped between described wear-resistant block 4 becomes chip area 5.
Further, described centralizer body two ends are respectively arranged with joint 6 and connect hole 7.
Further, described wear-resistant block 4 with the connected mode of groove 3 for welding.
Further, described centralizer rib body 2 hardness >=HRC33, described wear-resistant block 4 hardness >=HRC50.
Above-mentioned detailed description of the invention is only concrete case of the present utility model, and scope of patent protection of the present utility model includes
But be not limited to product form and the style of above-mentioned detailed description of the invention, any meet claims of the present invention and any belonging to skill
The those of ordinary skill in art field is suitably changed what it did or modifies, and all should fall into patent protection model of the present utility model
Enclose.
