Abstract
The utility model discloses a high-pressure-resistant falling-off-resistant double metal cylinder sleeve which comprise an upper end cap, a lower end cap, a metal outer sleeve, an abrasion-resistant metal inner sleeve, an upper locating pin and a lower locating pin. The metal outer sleeve and the abrasion-resistant metal inner sleeve are connected in a hot-pressing mode. The upper end cap and the lower end cap are in threaded connection with the metal outer sleeve and are located through the upper locating pin and the lower locating pin. The upper end cap and the lower end cap are in smooth transition with the abrasion-resistant metal inner sleeve. A certain taper degree is machined on each of the outer end faces of the inner walls of the upper end cap and the lower end cap. According to the high-pressure-resistant falling-off-resistant double metal cylinder sleeve, the problem that under high pressure, the abrasion-resistant metal inner sleeve in the double metal cylinder sleeve can easily fall off and be broken is solved, the high-pressure-resistant falling-off-resistant double metal cylinder sleeve is widely used in industries of petroleum, geological prospecting, chemical engineering and the like, service life of a product is greatly prolonged, and production cost of an enterprise is lowered.
Description
One, technical field
The utility model relates to a kind of slurry pump with high pressure resistant anti-dropping type bi-metal liner.
Two, background technique
High pressure slurry pump is oil drilling, geologic prospecting worktable " heart ", and mud slurry pump cylinder jacket is the important composition parts of slurry pump.The mud slurry pump cylinder jacket that uses is divided into monometallic cylinder sleeve or two kinds of structures of ceramic cylinder jacket at present: because industrial and mineral is very abominable, the monometallic cylinder sleeve is not wear-resisting, not corrosion-resistant, and working life is very short, and the ceramic cylinder jacket structure is too simple, under high pressure be easy to come off or fragmentation, still can not reach ideal effect.
Three, summary of the invention
The purpose of this utility model is to provide that a kind of structure is simple relatively, solid and reliable, wear-resistant, corrosion-resistant, not broken, the high pressure resistant anti-dropping type bi-metal liner of long service life.
The purpose of this utility model is achieved in that a kind of high pressure resistant anti-dropping type bi-metal liner, comprises cover (2) in upper plug head (3), lower end cap (5), metal-coating (1), the antifriction metal (AFM), last locating stud (4), following locating stud (6); Metal-coating (1) is that hot pressing is connected with the interior cover of antifriction metal (AFM) (2) Placement, upper plug head (3), lower end cap (5) and metal-coating (1) Placement are for being threaded and using locating stud (4), locating stud (6) location down, take smooth transition between the cover (2) in upper plug head (3), lower end cap (5) and the antifriction metal (AFM), certain tapering is processed in upper plug head (3), lower end cap (5) inwall exterior edge face.
A kind of high pressure resistant anti-dropping type bi-metal liner of the present utility model comprises cover in upper and lower plug, metal-coating, the antifriction metal (AFM), upper and lower locating stud; Metal-coating is connected mode with cover in the antifriction metal (AFM) be that hot pressing connects, upper and lower plug and metal-coating Placement are for being threaded and with upper and lower locating stud location, take smooth transition between the cover in upper and lower plug and the antifriction metal (AFM), certain tapering is processed in last lower end cap inwall exterior edge face.This structure has well solved under high pressure in the bi-metal liner frangible, the caducous problem of cover parts in the antifriction metal (AFM), and it is widely used in the industries such as oil, geologic prospecting and chemical industry, prolongs the working life of product greatly, reduces enterprise's cost of production.
Four, description of drawings
Fig. 1 is a kind of high pressure resistant anti-dropping type bi-metal liner vertical profile schematic representation of the utility model.
Five, embodiment
Below in conjunction with accompanying drawing the utility model is done detailed description.
As a kind of high pressure resistant anti-dropping type bi-metal liner of Fig. 1, comprise cover (2) in upper plug head (3), lower end cap (5), metal-coating (1), the antifriction metal (AFM), last locating stud (4), following locating stud (6); Metal-coating (1) is that hot pressing is connected with the interior cover of antifriction metal (AFM) (2) Placement, upper plug head (3), lower end cap (5) and metal-coating (1) Placement are for being threaded and using locating stud (4), locating stud (6) location down, take smooth transition between the cover (2) in upper plug head (3), lower end cap (5) and the antifriction metal (AFM), certain tapering is processed in upper plug head (3), lower end cap (5) inwall exterior edge face.
Claims (1)
1. a high pressure resistant anti-dropping type bi-metal liner comprises cover (2) in upper plug head (3), lower end cap (5), metal-coating (1), the antifriction metal (AFM), last locating stud (4), following locating stud (6); Metal-coating (1) is that hot pressing is connected with the interior cover of antifriction metal (AFM) (2) Placement, upper plug head (3), lower end cap (5) and metal-coating (1) Placement are for being threaded and using locating stud (4), locating stud (6) location down, take smooth transition between the cover (2) in upper plug head (3), lower end cap (5) and the antifriction metal (AFM), certain tapering is processed in upper plug head (3), lower end cap (5) inwall exterior edge face.
