風機運轉中的注意事項

來源： | 發布日期：2022-11-16

1.聽聲音
當 離心風機運轉中産生異常響聲時，很難迅速、正確地判斷其起因，須經充分調查。常見起因如下:進氣管吸入固體雜質;風機的定子與轉子摩擦;軸承有異常。此時往往在産生異響時伴有振動。同時，原動機及強制供油裝置産生的異響亦須注意。
2.檢查振動
与异响情况一样，风机产生剧烈振动的原因也很难直观地判断，亦须密切注意并充分的检查。产生振动的类型很多 : 因喘振等导致流体的力学振动;风机与原动机找正不好产生的振动 ; 风机安装不合理、轴承出现异常情况 ; 叶轮经长期运行平衡破坏造成振动的加剧 ; 转子与定子间的间隙有点或面的接触等情况造成的机械振动。轴承部位振动状态的判定见JB/T8689-1998《通风机振动检测及其限值》。
3.軸承的檢查
軸承溫度的測量對于了解軸承的工作情況是非常重要的，一般規定軸承溫升不得高于環境溫度40℃以上。另外，還應注意到潤滑油量及其汙染狀況、是否漏油、不同場合下的油溫及油壓等。對于使用冷卻水冷卻的 離心風機，還應注意冷卻水的水量、水溫等。對于采用油環式油潤滑軸承的風機，還應確認油環工作是否正常。
4.軸封部分的檢查
應經常檢查軸封部分泄漏的狀況、靜止部分與軸間的間隙或接觸情況，是否有一端接觸、發熱、振動治除異常、産生異響等情況。

"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."
