矽橡膠制品泄漏原因百科全書及改進建議

矽橡膠制品泄漏問題原因及改進自己意見

常見疵病

产生原因

改进意见

泄漏

1.安裝過程中損壞，即邊、角穿過孔時劃傷配合件；

2、壓縮量過小；

安装时将壳体末端加工成倒角，以保证安装时的 O 形

矽橡膠制品不受剪切而損壞；

2、適當的增加企業壓縮量；

大泄漏

1. 硅橡胶制品弹性损失

2. 橡胶 O 形环表面受摩擦损伤严重

3.矽橡膠制品收縮過大；

4、硅橡胶制品受密封工作介质进行腐蚀、溶胀；

5.間隙值過大，矽橡膠制品擠壓；

6. 硅橡胶制品一侧截面直径不一致，移动时变形损坏；

1、提高硅橡胶制品材料性能，延长使用使用寿命；

2、适当可以提高我国硅橡胶制品胶料硬度，减少贸易磨擦系数；

3.動態使用時，矽橡膠制品內徑應稍大于軸徑；

4. 提高橡胶邻环胶料的耐油性;

5、减小间隙值

6. 加强硅橡胶制品模型的尺寸控制和产品检验

密封圈進行早期出現損壞

1. 硅橡胶制品过度拉伸，过早断裂

2、安装时损坏

壓力過大，摩擦或剪切嚴重

选用橡胶 O 型圈或槽口尺寸不合适

1、动态使用时，硅橡胶制品内径应比轴径稍大；

2. 仅在安装过程中使用金属导套

3、减小压缩量；

4、正确选择 O 型橡胶圈与沟槽的组合

低溫泄漏

矽橡膠制品在低溫下失去彈性

提高矽橡膠制品膠料耐寒性

過度磨擦

1、压缩量过大；

橡胶 O 型圈溢流或耐油性差，过度膨胀;

1、减少压缩量或矫正沟槽尺寸可以提高中国金属材料表面的光洁度

2、采用挡圈防止中国硅橡胶制品溢出或提高我国硅橡胶制品材料的耐油性；

Except in such moments, however, the war seemed farther away than it had for months and months. But about eleven o'clock we began to find the way scored by the fresh ruts of heavy wheels and the dust deepened by hundred of hoofs. The tops and faces of the roadside banks were newly trampled and torn by clambering human feet. Here was a canteen, smashed in a wheel-track; yonder a fragment of harness; here lay a broken hame, there was the half of a russet brogan and yonder a ragged sock stained and bloody. "Lieutenant Ferry? he's unhurt--and so is Mr. Gholson! Mr. Gholson's gone to Franklin for doctors; Lieutenant Ferry sent him; he's been sending everybody everywhere faster than anybody else could think of anything!" "You would have removed me," Lawrence asked. "Must attend the inquest, sir," said the practical Prout. "Still, if that was my house, I'd pull it down if I couldn't sell it." In considering pneumatic machinery there are the following points to which attention is directed:— Father Coppens and I beseeched the German commanding officer to spare the houses of some people, large families, who came for shelter to the father's convent. And at length, after long supplications, we secured exemption for a few houses, inhabited by people who could not have done anything in a village which had been completely evacuated by the population, at the beginning of the fight. "Yes, sir," he answered, "that will be difficult enough. Everybody has fled, even my own wife and children. I remained because I thought it was my duty, and now I have been tramping through the streets already for over twenty-four hours, without being relieved. It seems that by far the greater number of my colleagues fled also." Besides Zeno, Parmenides seems to have had only one disciple of note, Melissus, the Samian statesman and general; but under various modifications and combined with other elements, the Eleatic absolute entered as a permanent factor into Greek speculation. From it were lineally descended the Sphairos of Empedocles, the eternal atoms of Leucippus, the Nous of Anaxagoras, the Megaric Good, the supreme solar idea of Plato, the self-thinking thought of Aristotle, the imperturbable tranquillity attributed to their model sage by Stoics and Epicureans alike, the sovereign indifference of the Sceptics, and finally, the Neo-platonic One. Modern philosophers have sought for their supreme ideal in power, movement, activity, life, rather than in any stationary substance; yet even among them we find Herbart partially reviving the Eleatic theory, and confronting Hegel’s fluent categories with his own inflexible monads. “I believe you!” Larry spoke earnestly, reassuringly. “It’s a perfectly reasonable explanation.” "I have heard o' the place. Lived there long?" "All right," assented Si, who had as little taste as his partner for seeming to weaken. "Here goes for a fight or a foot-race." TO: Fredk. Ramsbotham "Yes, but d?an't m?ake him angry—he might beat you." That summer old Mrs. Backfield became completely bedridden. The gratefulness of sunshine to her old bones was counteracted by the clammy fogs that streamed up every night round the farm. It was an exceptionally wet and misty summer—a great deal of Reuben's wheat rotted in the ground, and he scarcely took any notice when Tilly announced one morning that grandmother was too ill to come downstairs.
