Abstract
The utility model discloses a high-pressure-resistant anti-off-type ceramic cylinder liner which comprises an upper end cap, a lower end cap, a metal outer sleeve, a ceramic inner sleeve, an upper positioning pin and a lower positioning pin; the metal outer sleeve and the ceramic inner sleeve are connected in a hot pressing mode; the upper end cap and the lower end cap are connected with the metal outer sleeve in a screw thread mode, and the connection of the upper end cap, the lower end cap as well as the metal outer sleeve are positioned by the upper positioning pin and the lower positioning pin; the upper end cap and the lower end cap as well as the ceramic inner sleeve are in smooth transition; and the outer end surfaces of the inner walls of the upper end cap and the lower end cap are manufactured into certain taper. The problems that ceramic components in the ceramic cylinder liner under high pressure are easy to be fragile and are easy to fall off are solved well by the structure, the high-pressure-resistant anti-off-type ceramic cylinder liner is widely applied to industries of petroleum, geologic exploration as well as chemical engineering and the like, the service life of the product is prolonged greatly, and the production cost of the enterprise is lowered.
Description
One, technical field
The utility model relates to a kind of slurry pump with high pressure resistant anti-dropping type ceramic cylinder jacket.
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 at present is divided into bi-metal liner or two kinds of structures of ceramic cylinder jacket: because industrial and mineral is very abominable; Metallic cylinder 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 the utility model is to provide the high pressure resistant anti-dropping type ceramic cylinder jacket that a kind of structure is simple relatively, solid and reliable, wear-resistant, corrosion-resistant, be difficult for fragmentation, long service life.
The purpose of the utility model is achieved in that a kind of high pressure resistant anti-dropping type ceramic cylinder jacket, comprises cover (2) in upper plug head (3), lower end cap (5), metal-coating (1), the pottery, last locating stud (4), following locating stud (6); Metal-coating (1) is that hot pressing is connected with the interior cover of pottery (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 pottery, certain tapering is processed in upper plug head (3), lower end cap (5) inwall exterior edge face.
The high pressure resistant anti-dropping type ceramic cylinder jacket plug of the utility model comprises cover in upper and lower plug, metal-coating, the pottery, upper and lower locating stud; It is that hot pressing connects that metal-coating is connected mode with the interior cover of pottery; 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 pottery, certain tapering is processed in last lower end cap inwall exterior edge face.This structure has well solved under high pressure frangible, the caducous problem of ceramic component in the ceramic cylinder jacket, and it is widely used in the industries such as oil, geologic prospecting and chemical industry, prolongs the working life of product greatly, reduces the enterprise production cost.
Four, accompanying drawing and explanation
Fig. 1 is the high pressure resistant anti-dropping type ceramic cylinder jacket of a utility model vertical profile schematic representation.
Five, embodiment
Below in conjunction with accompanying drawing the utility model is done detailed description.
Like a kind of high pressure resistant anti-dropping type ceramic cylinder jacket of Fig. 1, comprise cover (2) in upper plug head (3), lower end cap (5), metal-coating (1), the pottery, last locating stud (4), following locating stud (6); Metal-coating (1) is that hot pressing is connected with the interior cover of pottery (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 pottery, 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 ceramic cylinder jacket comprises cover (2) in upper plug head (3), lower end cap (5), metal-coating (1), the pottery, last locating stud (4), following locating stud (6); Metal-coating (1) is that hot pressing is connected with the interior cover of pottery (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 pottery, certain tapering is processed in upper plug head (3), lower end cap (5) inwall exterior edge face.
