Background technology
At present, the manufacturing technology of equipment such as the high pressure plunger pump that domestic enterprise can grasp and produce, hydraulic planger pump, high pressure water cutter, cleaning machine, but higfh-tension ceramics plunger China can't produce.
Have zirconia ceramics plunger product now in high-end market; As the zirconia ceramics plunger that reaches 300-400Mpa pressure is mainly provided by offshore company; The external zirconia ceramics plunger producer that produces adopts the hot isostatic pressing mode mostly mainly in the U.S. and Germany, has reached fine quality.And the zirconia ceramics plunger quality product of domestic production can't be compared with the product that external manufacturer produces at all, can only occupy low-end market.Because homemade ceramic plunger is of poor quality, with low content of technology, can't satisfy market demand at all, therefore still to depend on import.
Mainly there is the problem of two aspects in domestic production zirconia ceramics plunger: the one, and the restriction of production unit.Because the stupalith production unit belongs to ceramic production technology equipment, and is strongly professional, requires the designer must be proficient in the stupalith technology, also to be proficient in the design of agglomerating plant simultaneously.So the difficulty that can't solve production unit is a universal phenomenon.If depend on the import production unit, cost an arm and a leg, the maintenance cost that can't bear especially, production cost is very high.The second, the technical matters research of ceramic new material and the problem of using.Domestic ceramic new material research lags behind developed countries such as America and Europe, and the high barrier of the high investment of novel material and technology causes China enterprise unhappy in the ceramic new material development.
Summary of the invention
The object of the present invention is to provide a kind of zirconia ceramics plunger, have high-quality, high strength, high-density, superior performance.
Another object of the present invention is to provide a kind of making method of above-mentioned zirconia ceramics plunger, adopt two-way concussion sintering process, make the stupalith density that is sintered reach ultimate attainment, superior performance.
Be to realize above-mentioned purpose, the present invention provides a kind of zirconia ceramics plunger, and its raw material comprises that component and weight part thereof are following: 92 ± 0.1 parts of zirconium whites, 5 ± 0.1 parts of yttrium oxides, and 3 ± 0.1 parts of thulium oxides.
The present invention also provides a kind of making method of above-mentioned zirconia ceramics plunger, comprises the steps:
Step 1, preparation of raw material: 92 ± 0.1 parts of zirconium whites, 5 ± 0.1 parts of yttrium oxides, and 3 ± 0.1 parts of thulium oxides;
Also comprise step 8, link processing: adopt two chromium, 13 steel loops, internal diameter adopts the coordinating size really up to the mark of 8 silks, under 1 barometric point, is heated to 250-300 ℃; Be inserted in zirconia ceramics plunger termination; Cooling, the zirconia ceramics plunger is held in the steel loop shrinkage tightly, accomplishes link and handles.
Said biscuit length is greater than zirconia ceramics plungers length 10mm, and the biscuit width is greater than zirconia ceramics diameter of plunger 3mm, and the biscuit height is the twice height of zirconia ceramics diameter of plunger.
Said step 4 sintering: when temperature is added to 1050 ℃-1150 ℃, add 150kg/cm
2Concussion adds 250kg/cm when temperature is added to 1510 ℃-1600 ℃
2Concussion, frequency is 100Hz, constant temperature was kept 2 hours and was kept concussion in 1510 ℃ of-1600 ℃ of temperature ranges.
The invention has the beneficial effects as follows: zirconia ceramics plunger of the present invention; Used high pressure concussion high temperature sintering technology; Through pressurization and employing pressurization concussion technology; Make and to be sintered the zirconia ceramics plunger matter is close more; Pore-free, no fine fisssure; Improve performance of products, improved the quality of production, guaranteed the stability of production quality; Produce high performance zirconia ceramics plunger through making method of the present invention, solved the problem that high performance zirconia ceramics plunger depends on import.
Description of drawings
Below in conjunction with accompanying drawing, describe in detail through specific embodiments of the invention, will make technical scheme of the present invention and other beneficial effects apparent.
In the accompanying drawing,
Fig. 1 is the making method schema of zirconia ceramics plunger of the present invention.
Embodiment
