Problems solved by technology

However, the quality of domestically produced zirconia ceramic plungers cannot be compared with those produced by foreign manufacturers, and they can only occupy the low-end market.
Due to the poor quality and low technical content of domestic ceramic plungers, they cannot meet the needs of the market at all, so they still have to rely on imports
[0004] There are two main problems in the domestic production of zirconia ceramic plungers: one is the limitation of production equipment
Therefore, it is a common phenomenon that the difficulties of production equipment cannot be solved
If you rely on imported production equipment, the price is expensive, and the maintenance cost is unaffordable, and the production cost is very high

Embodiment Construction

[0023] The invention provides a zirconia ceramic plunger, the raw materials of which include the following components and parts by weight: 92±0.1 parts of zirconia, 5±0.1 parts of yttrium trioxide, and 3±0.1 parts of thulium trioxide. The zirconia ceramic plunger has high quality, high strength, high density and superior performance.

[0024] Such as figure 1 Shown, the manufacture method of zirconia ceramic plunger of the present invention comprises the steps:

[0025] Step 1. Raw material preparation: Weigh the granulated powder according to a certain proportion, including 92±0.1 parts of zirconia, 5±0.1 parts of diyttrium trioxide, and 3±0.1 parts of dithulium trioxide.

[0026] Step 2, green body forming: the raw material is made into a cuboid green body by dry pressing; the length of the green body is the length of the subsequent zirconia ceramic plunger + 10mm, and the width of the green body is the diameter of the zirconia ceramic plunger +3mm, the height of the green...

Abstract

The invention provides a zirconia ceramic plunger and a manufacturing method thereof. The zirconia ceramic plunger comprises raw materials of, by weight, 92+ / -0.1 parts of zirconia, 5+ / -0.1 parts of yttrium oxide and 3+ / -0.1 parts of thulium oxide. The manufacturing method comprises steps of: step 1, raw material preparation; step 2, biscuit formation; step 3, charging; step 4, sintering; step 5, cooling; step 6, moulding by machining; step 7, surface light and fineness treatment to obtain the zirconia ceramic plunger. The zirconia ceramic plunger of the present invention utilizes a high pressure oscillation high temperature sintering technology; according to pressurization and the pressurization oscillation technology, the sintered zirconia ceramic plunger is more compact, has no pore or crack, so as to enhance product performance, improve production quality and guarantee stability of production quality.

Description

technical field [0001] The invention relates to the field of mechanical equipment manufacturing, in particular to a zirconia ceramic plunger and a manufacturing method thereof. Background technique [0002] At present, domestic enterprises have been able to master and produce high-pressure plunger pumps, hydraulic plunger pumps, high-pressure water cutters, washing machines and other equipment manufacturing technologies, but high-pressure ceramic plungers cannot be produced in my country. [0003] The existing zirconia ceramic plunger products in the high-end market, such as zirconia ceramic plungers with a pressure of 300-400Mpa, are mainly provided by foreign companies. Foreign manufacturers of zirconia ceramic plungers are mainly in the United States and Germany, and most of them use hot isostatic pressure method, to achieve a very good quality. However, the quality of zirconia ceramic plungers produced in China cannot be compared with those produced by foreign manufactu...
