Embodiment 1

[0012] Embodiment 1. The inner liner of the cylinder liner according to the present invention is ceramic matrix composite material, and the outer jacket is metal. The ceramic matrix composite material includes ceramics, zirconia, tungsten oxide, chromium oxide, molybdenum oxide, and resin materials.

[0013] The configuration ratio of the first component ceramic material is 60-80%;

[0014] The second component is zirconia, tungsten oxide, chromium oxide, and molybdenum oxide. The composite component is 15-30; among them, zirconia accounts for 30-60% of this component, tungsten oxide 20-40%, and chromium oxide 10-15% %, molybdenum oxide 10-15%.

[0015] The third component is 5-25% of resin material.

Embodiment 2

[0016] Embodiment 2, its preparation method is: the first step all above materials are pulverized into micropowder.

[0017] In the second step of mixing, fully mix the zirconia, tungsten oxide, chromium oxide and molybdenum oxide of the second component.

[0018] The third step is graded mixed spraying, the first stage high pressure spraying: high pressure spray ceramic material on the inner wall of the metal sleeve; then high pressure spray the composite component of the second component; then high pressure spray resin material; second stage high pressure spray: first High-pressure spray ceramics on the inner wall of the first stage; then high-pressure spray the composite components of the second component; then high-pressure spray resin materials; third high-pressure spray: first spray resin materials on the inner wall of the second stage; then high-pressure spray ceramic materials; High-pressure spraying of the second component of the compound.

Embodiment 3

[0019] Embodiment 3, three-level control is set, that is, each level is 0.04mm, and high-pressure spraying is used between the three-level layers, and the high pressure is 4 atmospheres.

Abstract

The invention discloses a slurry pump spraying type cylinder sleeve and a preparation method, and relates to an oil field slurry pump cylinder sleeve technology. A cylinder sleeve lining is made of a ceramic matrix composite material, an outer sleeve is made of metal, and the ceramic matrix composite material comprises ceramic, zirconium oxide, tungsten oxide, chromic oxide, molybdenum oxide and a resin material.

Description

technical field [0001] The invention relates to an oil field mud pump cylinder sleeve technology, in particular to a mud pump spray-coated cylinder sleeve and a preparation method thereof. Background technique [0002] Slurry pumps have been widely used in mining, metallurgy, chemical industry, petroleum and other industrial production. Piston mud pumps are often used in industrial processes that require high pressure. The early typical structure is a double-cylinder double-acting pump. The advantage of this structure of the mud pump is that it is more reliable in use. The disadvantage is that the pump is large in size and heavy in weight. , low efficiency, and relatively large pressure fluctuations. By the mid-1960s, a three-cylinder single-acting mud pump with better performance was developed. Its advantages are high efficiency, relatively small pressure fluctuations, small volume, and light weight. After more than 40 years of continuous improvement and perfection, this t...
