Abstract
A cylinder liner of a mud pump for oil drilling and production comprises an outer cylinder liner and an inner cylinder liner. The inner cylinder liner is inlaid in the outer cylinder liner and is made of ceramic materials, and the thickness of the pipe wall of the inner cylinder liner ranges from 8mm to 10mm. The inner cylinder liner is made of the ceramic materials, so that corrosion resistance of the cylinder liner to acid, alkali, salt and the like in mud generated during oil exploitation is greatly improved; the cylinder liner is resistant to the temperature higher than 1500 Celsius degrees, and the requirement on the high-temperature resistance in a super-depth drilling and production process can be met assuredly; and the cylinder liner is high in abrasion resistance, the service life of the cylinder liner can reach 6000 hours per piece, the work intensity is reduced to a great extent, loss of steel materials and rare earth materials is reduced, and the cost is saved for a manufacturing enterprises and the oil exploitation industry. Besides, the cylinder liner is high in technical content, can replace the traditional cylinder liner and a bimetal cylinder liner of a mud pump, and is extremely wide in market prospect.
Description
Technical field
The utility model relates to the petroleum production mechanical manufacturing field, is a kind of petroleum drilling and mining mud slurry pump cylinder jacket specifically.
Background technique
The petroleum drilling and mining mud slurry pump cylinder jacket is the requisite important accessory of oil development, and belongs to the accessory of high flow rate.Only 120-180 hour traditional cylinder sleeve operating time, namely need scrap replacing, the bimetal mud slurry pump cylinder jacket operating time of existing market application can reach 600-680 hour, increase working life, but its high temperature resistance and anticorrosive still undesirable, in recent years marine petroleum exploitation has had higher stricter requirement to product, especially high temperature resistant and corrosion-resistant on requirement higher.The bimetal mud slurry pump cylinder jacket can not satisfy its needs, and undercoating adopts high-temperature wearable precious metal method, because the variation of cylinder body build under high temperature condition causes the effect used still undesirable.Research and develop the petroleum drilling and mining mud slurry pump cylinder jacket of corrosion-resistant, high temperature resistant and long-life, extremely urgent.
Summary of the invention
In sum, the purpose of this utility model is to provide a kind of petroleum drilling and mining mud slurry pump cylinder jacket.
The utility model is achieved through the following technical solutions:
A kind of petroleum drilling and mining mud slurry pump cylinder jacket is comprised of outer cylinder sheath and inner cylinder liner, and inner cylinder liner is embedded in the outer cylinder sheath; Inner cylinder liner adopts stupalith, its thickness of pipe wall 8 ~ 10mm.
Outer cylinder sheath of the present utility model adopts the casting of plain carbon steel high speed centrifugation, carries out fine finishing again; Inner cylinder liner adopts potter's clay, forms by the designing requirement sintering, again by interior outer grinding, reaches for subsequent use behind the standard piece; Utilize at last heat treatment that inner cylinder liner is bumped into outer cylinder sheath.
Advantage of the present utility model and beneficial effect:
1, inner sleeve of the present utility model adopts stupalith, and during petroleum production, the acid in the mud, alkali, salt etc. have high corrosion resistance, and high temperature resistant reaching more than 1500 degrees centigrade, can guarantee the high temperature resistant demand in the high depth drilling process.
2, the utility model adopts stupalith, has simultaneously high wear resistance, and the life-span can reach 6000 hours/part, and greatly degree has reduced working strength, has reduced the loss of steel and rare earth material, has reduced the cost of manufacturing enterprise and the cost of petroleum production.
3, the utlity model has than high-tech content, alternative traditional cylinder sleeve and bimetal mud slurry pump cylinder jacket, its market prospects are extremely wide.
