Abstract

One oil pump for engine ceramic-seal ring of the present invention, the present invention relates to the Sealing Technology of pump or valve, it is specifically related to auto industry ceramic seal loop technique, it is characterized in that: by sealing ceramic layer and resistance to compression ceramic layer by second time sintering integrator, seal ceramic layer and use: 10～25% aluminium oxide, 20～45% silicon oxide, 5～8% chromium carbide, 3～9% bismuth oxide, 3～12% Zirconium orthosilicate., 6～15%PbBi2212,3～13%Mo2C；Resistance to compression ceramic layer uses: 12～28% aluminium oxide, 32～72%32～72% silicon oxide, 8～16% magnesium oxide, 5～12% wollastonite, 5～18% magnesium chloride hexahydrate, 1～5%LaNiO3,4～6% molybdenum carbide.In place of the present invention not only solves the deficiencies in the prior art, also there is the advantage that fusing point is high, hardness is big, wear resistence is strong, smooth surface, resistance are little.

Description

A kind of oil pump for engine ceramic-seal ring
Technical field
The present invention relates to the production equipment of a kind of ceramic tile, be specifically related to the production mould of ceramic tile.
Background technology
Auto industry sealing ring is mainly following several with adopting now: elastomeric material, asbestos material and metal material；
1. the weak point of rubber packing material be the most aging, tolerable temperature pressure is low, corrosion-resistant, outer due to The elasticity in rubber school itself increases the frictional force between encapsulant and the pump housing, exacerbates abrasion between the two, makes out again Closing valve is the most laborious；
2. life-span deficiency short, perishable deposited by asbestos seal material, needs often to change encapsulant；
3. metallic sealing material sealing is poor, and decay resistance is the best；
Also there is ceramic sealing material in market now, and great majority are carborundums, but produces micro-on high-temperature sintering process surface Hole, owing to the characteristic of the heat of micropore ring on surface and the pressure texture of mechanical performance reduces, furthermore when Laser Surface Treatment, pottery Porcelain structure easily occurs that micro-crack deforms, and causes rupturing when pressurized.
Summary of the invention
One oil pump for engine ceramic-seal ring of the present invention, in place of not only solving the deficiencies in the prior art, also has The advantage that fusing point is high, hardness is big, wear resistence is strong, smooth surface, resistance are little.
For achieving the above object, the present invention is by the following technical solutions: by sealing ceramic layer and resistance to compression ceramic layer by the Double sintering integrator；
Described sealing ceramic layer uses following material to fire by weight proportion and forms:
10～25% aluminium oxide, 20～45% silicon oxide, 5～8% chromium carbide, 3～9% bismuth oxide, 3～12% silicic acid Zirconium, 6～15%PbBi2212,3～13%Mo2C；
The resistance to compression ceramic layer stated uses following material to fire by weight proportion and forms:
12～28% aluminium oxide, 32～72% silicon oxide, 8～16% magnesium oxide, 5～12% wollastonite, 5～18% 6 water Magnesium chloride, 1～5%LaNiO3,4～6% molybdenum carbide.
Detailed description of the invention
The elastic gum of a kind of ceramic tile core rod, by sealing ceramic layer with resistance to compression ceramic layer by second time sintering integrator；
Described sealing ceramic layer uses following material to fire by weight proportion and forms:
21% aluminium oxide, 43% silicon oxide, 6% chromium carbide, 6% bismuth oxide, 5% Zirconium orthosilicate., 11%PbBi2212,8% Mo2C；
The resistance to compression ceramic layer stated uses following material to fire by weight proportion and forms:
20% aluminium oxide, 41% silicon oxide, 12% magnesium oxide, 9% wollastonite, 10% magnesium chloride hexahydrate, 3%LaNiO3, 5% molybdenum carbide.
In place of not only solving the deficiencies in the prior art, also have that fusing point is high, hardness is big, wear resistence is strong, smooth surface, resistance The advantage that power is little.
Last it is noted that obviously, above-described embodiment is only for clearly demonstrating example of the present invention, and not Restriction to embodiment.For those of ordinary skill in the field, can also make on the basis of the above description The change of other multi-form or variation.Here without also cannot all of embodiment be given exhaustive.And thus amplified Go out obviously changes or changes among still in protection scope of the present invention.
