風機葉輪有哪些腐蝕現象?應采取什麽處理措施?

來源： | 發布日期：2022-12-02

答:離心風機 葉輪的腐蝕現象不但普遍，而且危害很大。輸送二氧化硫、氯氣等腐蝕性氣體必然要産生嚴重的腐蝕，處理各種非腐蝕氣體的風機葉輪也會受到預料不到的腐蝕。特別是葉輪的局部腐蝕會導致葉輪的損壞。因此，離心風機運行前，必須掌握氣體介質的精確成分，以便采取防腐蝕的措施。

叶轮产生腐蚀时，应采取如下措施进行处理:

1)重新分析气体介质的成分和使用的材料。

2)对介质为二氧化硫和氯气的，要检测其混人水分的含量，然后采取适当处理施。因为该两种介质除了干燥状态外，难有耐其腐蚀的材料。

3)检查防腐蚀材料的脱落情况。

防腐蚀被覆材料有:薄不锈钢板、液态金属喷镀、金属喷涂所构成的金属被覆材料以及由涂料、橡胶、乙烯树脂等构成的非金属被覆材料。

若因腐蚀而造成转子不平衡，引起过大振动的，可以采用普通钢贴补的应急措施，但必需在短时间内更换耐久的处理件。

在腐蚀中，全面腐蚀比较容易处理，而沟槽腐蚀和间隙腐蚀等局部腐蚀或点蚀的腐蚀速度比较快，危险性要大。因此要特别注意。

"But this does not explain him," broke in the Doctor, bitterly. "As I remarked before," Gregg resumed, coolly, "you were not in a fit state to carry[Pg 182] out the investigation. You could not bring yourself to accept even the obvious. Fortunately you remembered some of the most salient facts. Those tubes fitted into the clock, for example; I regard those as highly suggestive. Think of it, Allingham! The energy of generations compressed into a tube and so utilised by a single individual. For that is what must have happened in the year 8000. The scientists must have discovered means of gathering up and storing nervous energy. Everybody has this extra reserve of force. That solved one problem. Then there was the question of a better distribution. They had to invent a new nervous system. If we ever have an opportunity of examining the Clockwork man thoroughly, we shall find out what that system is. Speaking in rough terms, we may assume that it is probably an enlargement of the compass of what we call afferent and efferent impulses. There will also be new centres, both of reflex and voluntary action. Each impulse, in this new system, has a longer range of effectiveness, a greater duration in time." Civil engineering, when spoken of, will be assumed as referring to works that do not involve machine motion, nor the use of power, but deal with static forces, the strength, nature, and disposition of material under constant strains, or under measured strains, the durability and resistance of material, the construction of bridges, factories, roads, docks, canals, dams, and so on; also, levelling and surveying. This corresponds to the most common use of the term civil engineering in America, but differs greatly from its application in Europe, where civil engineering is understood as including machine construction, and where the term engineering is applied to ordinary manufacturing processes. For pulleys, gear wheels, or other standard parts of machinery which are not likely to be modified or changed, iron patterns are preferable; patterns for gear wheels and pulleys, when made of wood, aside from their liability to spring and warp, cannot be made sufficiently strong to withstand foundry use; besides, the greatest accuracy that can be attained, even by metal patterns, is far from producing true castings, especially for tooth wheels. The more perfect patterns are, the less rapping is required in drawing them; and the less rapping done, the more perfect castings will be. (1.) Why are shaping machines better adapted than planing machines for planing slots, key-ways, and so on?—(2.) What objects are gained by a quick return motion of the cutter bar of shaping machines? I. “Oh, I think he’s all right,” argued Larry. “But stop and think of these things,” he continued, urging his two friends to use their own imaginations. “The amphibian was old-looking and didn’t seem to be much good, and the gas gauge was broken, and the chewing gum was quite fresh. That might look as though——” The Chiricahuas might stay there and fire at intervals as long as they listed, killing a few men perhaps. And then they might retreat quite safely, putting the barrier[Pg 277] between themselves and the pursuers. Obviously there were only two courses wherein lay any wisdom,—to retreat, or to cut off their retreat. Landor said so to the major in command. THAT evening Lieut. Bowersox sent a telegram to Deacon Klegg. It had to be strictly limited to 10 words, and read: "Why, you shoved our car out there into the brush and went off and left us. We thought we had to look out for ourselves," explained Harry. "Can't we hang 'em, anyway?" he added in an appealing tone, and the rest of the boys looked wistfully at Si for permission to proceed. "Trust Corpril Elliott," said Gid, returning to his old partisanship of the taller veteran. "He knows his business every time." Chapter 21 "Rose, marry me." "The bondman may be freed," replied the man who had before spoken; "but when shall the freeman be righted? I took little heed of these things when I heard you preach freedom to the villeins two years ago: but my children have been sick; my wife has been struck with a palsy; and I, who had not a penny to call my own, gave eleven groats yesterday for myself, my wife, and the two boys; and to-morrow must I sell the last blanket that covers her, to pay the twelfth."
