南通電氣防爆檢測机构提醒：危险场所防爆電氣檢測是必要的

2021-4-26 21:51:21

在危險場所使用的防爆電氣産品能否確保防爆安全，不僅取決于産品本身制造的質量和檢驗部門定期對産品提供高防爆安全性檢測，而且也取決于産品用戶部門的安全使用。

性能質量再好的防爆電氣産品如果使用不當，不僅不能起到防爆作用，甚至可能成爲危及安全的可怕殺手。許多慘痛的爆炸事故都證明了這點。

例如，防爆電氣産品電纜引入裝置中的橡膠密封圈，是一個保持産品防爆性能的重要零件，這個零件在使用中往往被人們所忽視，不能被正確的選型、安裝和維護。如有的用戶在維修後未將其壓緊，有的選用的密封圈尺寸和材質不符合標准要求，有的檢修後幹脆不安裝密封圈。結果就使危險場所中的可燃性氣體可以暢通無阻地進入接線盒空腔內。一旦接線盒內的接線端子的連接處出現電弧火花時，就可能點燃可燃性氣體引起爆炸。

類似這種不能安全使用防爆電氣産品而引起爆炸事故的例子在爆炸事故總的統計中占有很大的比例。

由此可見，防爆電氣産品的安全使用和定期檢測和反映防爆電氣産品安全性能的制造質量是同等重要的。

因此，危险场所防爆電氣檢測是必要的，定期对在使用中的防爆电气设备进行防爆现场检查，不仅仅是安全生产部门的要求，更是企业对自身的生命、财产安全的重视。

"Then be kind enough to change me a dollar bill," said the stranger, drawing the beaver skin from under his coat and laying it on the counter. The nondescript individual whom we saw among the passengers early in the voyage had joined the party, and heard the story of Captain Hunting's[Pg 68] whale. When it was ended, he ventured to say something on the subject of whaling. "But if she should be at Wiggins--" "I prayed for you." Second. Impact wheels, driven by the force of spouting water that expends its percussive force or momentum against the vanes tangental to the course of rotation, and at a right angle to the face of the vanes or floats. "So this brave lady succeeded in getting the sentence of death withdrawn. But the Germans wanted to torture their wretched prisoners on any or no plea. They were placed near the church wall, kept standing there all night, were told that they would be shot by and by, and threatened by the soldiers with their bayonets. "Yes, men, what the gentleman says is true." But a profounder analysis of experience is necessary before we can come to the real roots of Plato’s scheme. It must be remembered that our philosopher was a revolutionist of the most thorough-going description, that he objected not to this or that constitution of his time, but to all existing consti254tutions whatever. Now, every great revolutionary movement, if in some respects an advance and an evolution, is in other respects a retrogression and a dissolution. When the most complex forms of political association are broken up, the older or subordinate forms suddenly acquire new life and meaning. What is true of practice is true also of speculation. Having broken away from the most advanced civilisation, Plato was thrown back on the spontaneous organisation of industry, on the army, the school, the family, the savage tribe, and even the herd of cattle, for types of social union. It was by taking some hints from each of these minor aggregates that he succeeded in building up his ideal polity, which, notwithstanding its supposed simplicity and consistency, is one of the most heterogeneous ever framed. The principles on which it rests are not really carried out to their logical consequences; they interfere with and supplement one another. The restriction of political power to a single class is avowedly based on the necessity for a division of labour. One man, we are told, can only do one thing well. But Plato should have seen that the producer is not for that reason to be made a monopolist; and that, to borrow his own favourite example, shoes are properly manufactured because the shoemaker is kept in order by the competition of his rivals and by the freedom of the consumer to purchase wherever he pleases. Athenian democracy, so far from contradicting the lessons of political economy, was, in truth, their logical application to government. The people did not really govern themselves, nor do they in any modern democracy, but they listened to different proposals, just as they might choose among different articles in a shop or different tenders for building a house, accepted the most suitable, and then left it to be carried out by their trusted agents. We've accepted, so please don't object, Daddy dear. heat of the going they get so breathless and panting that they lose The young prince then goes on his way in search of the magical flower. He is about to rest awhile in a cavern, but at the moment when he lies down on a stone it is transformed into a monster made of bladder, which rears itself enraged in the air with a trumpet-cry. By good luck the king's son calls upon the aid of the prophet Suleiman, whom the dragon also reveres, and the pacified monster conveys Tazulmulook to the garden of Bakaoli, and, moreover, gives him a ring which will be a talisman in danger. But the minister still refused to see it. He looked him very squarely in the eyes now, however. "See here, I am going to take lemon pop, my friend," he said. Nevertheless she decided that it might be best to tell her husband, and she did so as they sat together by the fire after the moon had risen into the small stretch of sky above the mountain peaks. They had bought a live sheep that day from a Mexican herder who had passed along the road, and they were now cutting ribs from the carcass that hung from the branch of a near-by tree, and broiling them on the coals. Felipa finished an unimpassioned account of the afternoon's happenings and of Alchesay's advice, and Landor did not answer at once. He sat thinking. Of a sudden there was a rustle and a step among the pines, and from behind a big rock a figure came out into the half shadow. Felipa was on her feet with a spring, and Landor scrambled up almost as quickly. "The one built of poles? Yes." "On Saturday, July 30, Dr. Johnson and I took a sculler at the Temple-stairs, and set out for Greenwich. I asked him if he really thought a knowledge of the Greek and Latin languages an essential requisite to a good education. JOHNSON. 'Most certainly, Sir; for those who know them have a very great advantage over those who do not. Nay, Sir, it is wonderful what a difference learning makes upon people even in the common intercourse of life, which does not appear to be much connected with it.' 'And yet, (said I) people go through the world very well, and carry on the business of life to good advantage, without learning.' JOHNSON. 'Why, Sir, that may be true in cases where learning cannot possibly be of any use; for instance, this boy rows us as well without learning, as if he could sing the song of Orpheus to the Argonauts, who were the first sailors.' He then called to the boy, 'What would you give my lad, to know about the Argonauts?' 'Sir, (said the boy) I would give what I have.' Johnson was much pleased with his answer, and we gave him a double fare. Dr. Johnson then turning to me, 'Sir, (said he) a desire of knowledge is the natural feeling of mankind; and every human being, whose mind is not debauched, will be willing to give all that he has, to get knowledge.'" Reuben did not in the least mind being flogged—it was all in the day's work—and showed scant sympathy for those fellow-criminals who cried for their mothers. Most of the cramp and stiffness had worn off, and his only anxiety was to have the thing over quickly, so that he could be home in time for supper. The nightmare had its appropriate ending. Sixty[Pg 297] dead beasts were burned in lime. Boarzell became Hinnom—it was the most convenient open space, so Reuben's herd was burned on it. From a dozen different pyres streamers of white smoke flew along the wind, and a strange terrible smell and tickling of the nostrils troubled the labourer on the westward lands by Flightshot or Moor's Cottage. The house was swimming in the light of the western moon. Its strange curves and bulges, its kiln-shaped ends, and great waving sprawl of roof all shone in a white glassy brilliance, which was somehow akin to peace. There was a soft flutter of wind in the orchard and in the sentinel poplars, while now and then came that distant night-purged scrap of song: The day was favourable for the pageant, and the houses seemed to vie with each other in the variety of their silken colours and tinselled ornaments, glowing and glittering in the morning sun. At Cornhill, indeed, the meretricious adornments of art were superseded for a brief space by the simple beauty of nature, and the eye felt a momentary relief in resting on the green grass, and the few shaded trees that covered the open ground. But this green spot was succeeded by a dense mass of dwellings covered with hangings of a richness suitable to the reputed wealth of the city merchants; here the scene was animated in the extreme,—the motions of the crowd became unsteady and irregular, as they were actuated at once by eagerness to hurry on, and a desire to linger among the rainbow diversity of hues around them, and the glowing beauty which, arrayed with costly elegance, and smiling with anticipated enjoyment, graced every open window.
