Problems solved by technology

[0002] High-pressure mud pumps are important equipment for geological exploration and oil drilling workbenches, and cylinder liners are key components of high-pressure mud pumps. Most of the existing cylinder liners are made of metal materials, which not only have poor chemical corrosion resistance, but also are wear-resistant. The performance is not good, especially for some oil fields with harsh geological conditions, its service life is short, generally no more than 300 hours, the service life of the ceramic cylinder liner developed by Reed Company of the United States can reach 2500 hours, but the price is very expensive, that is, the price is 12,000 yuan / set; a few colleges and universities in China have also carried out research on ceramic cylinder liners, but due to the inappropriate methods used, they have not yet been mass-produced

Embodiment Construction

[0020] A method for preparing a ceramic cylinder liner of a high-pressure mud pump for drilling, which is completed by the following ceramic raw materials and steps:

[0021] The weight proportion of each raw material is:

[0022] α-Al 2 o 3 92 parts, MgO 1 part.

[0023] Y 2 o 3 -La 2 o 3 1 part, BaO 1 part.

[0024] ZrO 2 1.5 parts, CaO 1 part.

[0025] SiO 2 0.8 copies;

[0026] The steps described are as follows:

[0027] (1) Using wet ball milling, put the above-mentioned raw materials in the weight ratio into the ball mill, then add water, add 0.6 parts of binder and 0.6 parts of dispersant and carry out ball milling for 12 hours to obtain slurry, and the input of raw materials, ball stones and water The quantities are raw materials: ball stone: water = 1: 1.6: 0.5,

[0028] The binder is polyvinyl alcohol, the dispersant is DOlaPixCE64, and the water is deionized water;

[0029] (2) Spray granulation is carried out by conventio...

Abstract

The invention relates to a manufacture method of the ceramic cylinder jacket of high-pressure sludge pump for drilling, in which using zirconium oxide plasticized alumina (a-Al 203) as a matrix, leading in Zr 02 and Y 203-La 203 rare earth composite additive by using the modern plasticizing and reinforcing technology and adopting the isostatic compaction technology makes green bodies have uniformity and compactness. Because of using the atmospheric high-temp. drawer kiln once-through sintered, the temperature is distributed uniformly.
