Abstract
The utility model discloses a sludge pump ceramic cylinder casing which comprises a metal casing and an internal liner, wherein the metal casing is hooped on the internal liner, the internal liner is made of zirconia toughened alumina or pure zirconia, the metal casing is hooped on the internal liner, a groove and a lug boss are arranged on the metal casing, and a neck is arranged on the lug boss. Because the zirconia toughened alumina or pure zirconia ceramics is used as the internal liner, the zirconia toughened alumina ceramics and the zirconia ceramics have best wear-resisting property and better chemical resistance; and the part where a sludge pump or other mechanical parts match with the cylinder casing are provided with the groove and the neck, thereby causing the assembly of the cylinder casing and the sludge pup or other mechanical parts to be firm without easily shedding, saving the maintenance time, and lowering the labour cost so as to reduce the product cost.
Description
Technical field
The utility model relates to the cylinder sleeve field, relates to the lined ceramics cylinder sleeve that a kind of mud pump for petroleum drilling is used specifically.
Background technique
High pressure slurry pump is oil drilling worktable " heart ".Mud slurry pump cylinder jacket promptly is the vitals of slurry pump, is again the easily worn part of drilling pump, and its working life is by the problem of extensive concern.The cylinder sleeve that uses mostly is bi-metal liner at present.Because working condition abominable (pump pressure 17-35MPa, piston jig frequency 100-120 time/minute, 70-170 ℃ of friction temperature rise, alkalescence PH9-10, mud sand content 3-5%), Metallic cylinder is wear-corrosion resistance not, and working life is short, at complex formation or petroleum reservoir when dark (more than 6000 meters), thereby usually need change and have a strong impact on drilling efficiency, for offshore oil, the construction of natural gas fields, Metallic cylinder is more difficult to overcome a corrosion-prone difficult problem, the back of Metallic cylinder and slurry pump assembling simultaneously easily comes off when using, and influence is produced.
Summary of the invention
The purpose of this utility model with regard to be to provide a kind of corrosion resistant, wear-resisting, long service life, with the slurry pump ceramic cylinder jacket of slurry pump assembling difficult drop-off.
The purpose of this utility model can be achieved through the following technical solutions:
A kind of slurry pump ceramic cylinder jacket, it comprises metal-coating and liner, and the metal-coating lock ring is on liner, and liner is Zirconia reinforced alumina or pure zirconia goods.
Above-mentioned slurry pump ceramic cylinder jacket, described metal-coating lock ring is on liner, and metal-coating is provided with groove and boss, is provided with draw-in groove on boss, wherein groove on the metal-coating and draw-in groove are assemblied on the corresponding site of slurry pump, make it assemble fastening difficult drop-off.
The utility model is owing to adopt Zirconia reinforced alumina ceramic or pure zirconia pottery to make liner, Zirconia reinforced alumina and zirconia ceramics, pure zirconia pottery and general ceramic performance such as following table 1, wear-resisting property is fabulous as can be seen from Table 1, Zirconia reinforced alumina ceramic and zirconia ceramics have good chemical resistance, it is the erosion of a lot of organic substances of ability also, simultaneously good electrically insulating material, and be provided with groove and draw-in groove in the place that slurry pump or other mechanical parts and cylinder sleeve match, make that like this assembling of cylinder sleeve and slurry pump or other mechanical parts is fastening, difficult drop-off during use, save engineering time, thereby reduced the product cost that labour cost reduces.
Following following table 1 is the performance table of conventional ceramic and Zirconia reinforced alumina ceramic, zirconia ceramics
Table 1

Description of drawings
Accompanying drawing is a structural representation of the present utility model.
Embodiment
A kind of as shown in drawings slurry pump ceramic cylinder jacket, it comprises metal-coating 4 and liner 1, the metal-coating lock ring is on liner, liner 1 is the Zirconia reinforced alumina goods, institute's metal-coating lock ring is on liner, and metal-coating is provided with groove 5 and boss 3, is provided with draw-in groove 2 on boss 3.
Above-mentioned slurry pump ceramic cylinder jacket, liner can also be the pure zirconia goods.
The boss of cylinder sleeve, groove and draw-in groove and slurry pump corresponding site close fit make cylinder sleeve and slurry pump tighten together during use, and difficult drop-off during use has been saved engineering time, thereby have reduced the product cost that labour cost reduces.
