Abstract
The utility model discloses a lining engineering ceramic cylinder for mud pump, comprising an upper bulkhead, a lower bulkhead, a metal jacket and an engineering ceramic inner sleeve. The connecting type of the metal jacket and the engineering ceramic inner sleeve is a heat pressing connection. The upper bulkhead (the slurry outlet bulkhead) and the metal jacket form into a whole. The connecting type of the lower bulkhead and the metal jacket is a heat pressing connection. The out end face of the inner walls of the upper and the lower bulkheads are processed to form a certain taper.
Description
One, technical field
The utility model relates to a kind of slurry pump liner engineering ceramics cylinder sleeve.
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 bi-metal liner or two kinds of structures of liner engineering ceramics cylinder sleeve at present: because operating mode is very abominable, Metallic cylinder is not wear-resisting, not corrosion-resistant, and working life is very short; Liner engineering ceramics cylinder sleeve or structure are too simple, under high pressure be easy to come off or fragmentation, or structure are too complicated, and can not guarantee that still liner engineering ceramics cylinder sleeve under high pressure is not broken.
Three, summary of the invention
The purpose of this utility model is to provide a kind of slurry pump liner engineering ceramics cylinder sleeve simple in structure, solid and reliable, wear-resistant, corrosion-resistant, long service life.
The purpose of this utility model is achieved in that a kind of slurry pump liner engineering ceramics cylinder sleeve, comprise cover in mud outlet end plug, lower end cap, metal-coating, the engineering ceramics, it is characterized in that: metal-coating is connected mode with cover in the engineering ceramics be that hot pressing connects, mud outlet end plug and metal-coating are combined into an integral body, lower end cap is that hot pressing is connected with the metal-coating Placement, and certain tapering is processed in mud outlet end plug, lower end cap inwall exterior edge face.
The utility model slurry pump liner engineering ceramics cylinder sleeve, comprise cover in mud outlet end plug, lower end cap, metal-coating, the engineering ceramics, metal-coating is connected mode with cover in the engineering ceramics be that hot pressing connects, mud outlet end plug and metal-coating are combined into an integral body, the lower end plug is that hot pressing is connected with the metal-coating Placement, and certain tapering is processed in mud outlet end plug, lower end cap inwall exterior edge face.Simple in structure like this, cover can not slide with metal-coating in the engineering ceramics, cooperate each other solid and reliable, cover difficult drop-off and fragmentation in the engineering ceramics, long service life.
Four, accompanying drawing and explanation
Fig. 1 is the utility model longitudinal profile structural representation.
Fig. 2 is the utility model horizontal section structural representation.
Among the figure: 1-mud outlet end plug, cover in the 2-metal-coating, 3-engineering ceramics, 4-lower end cap
Five, embodiment
Below in conjunction with embodiment and contrast accompanying drawing the utility model is described in further detail.
As seen from Figure 1, Figure 2, a kind of slurry pump liner engineering ceramics cylinder sleeve, comprise cover 3 in mud outlet end plug 1, lower end cap 4, metal-coating 2, the engineering ceramics, it is characterized in that: metal-coating 2 is that hot pressing is connected with the interior cover of engineering ceramics 3 Placements, mud outlet end plug 1 is combined into an integral body with metal-coating 2, lower end cap 4 is that hot pressing is connected with metal-coating 2 Placements, and certain tapering is processed in mud outlet end plug 1, lower end cap 4 inwall exterior edge faces.
