爲中國航天集團川南機械廠研制的防爆試驗機

三思泰捷與中航集團的合作由來已久，我們多年來爲中航集團所屬的企業和科研項目提供過試驗解決方案。今天要介紹的，是一款特殊的防爆試驗機，是我司爲中航集團下屬的川南機械廠專門研制生産的。

川南機械廠，位于四川泸州，即中國航天科技集團公司火工技術研究所（內部稱爲692廠）創建于1970年，是航天火工品專業研制生産單位，航天火工裝置和石油民爆器材的研制開發，承擔了國家高新工程科研任務。該廠先後爲我國長征系列運載火箭、衛星和神舟飛船等航空航天型號配套研制生産火工元件和火工裝置，並因在神舟五號載人航天工程中表現突出而榮獲全國五一勞動獎狀。

該廠也生産民品，爲大港、中原、勝利、新疆、海洋等我國大型油田配套研制生産民爆器材及石油鑽采工具，爲我國石油射孔、鑽采手段國産化提供了設備支撐。

在石油行业，对于材料及器件有着特殊的抗压要求，由于其工况条件的限制，其需要在高压环境下保持其性能安全可靠，有时还需要面临易燃易爆气体的环境。所以，防爆試驗機也就应运而生了。

此次爲客戶研制的此款專用試驗機，配置了防爆正壓櫃。防爆正壓櫃的工作壓力通常在50Pa≤P≤1000Pa之間，當氣壓高于1000Pa時，泄壓閥自動開啓排氣閥，自動調整內部氣壓，保證産品不受高氣壓沖擊而變形損壞；當氣壓低于50Pa時，自控系統自動發出報警以及輸出報警信號，需調整內部壓力，補氣成功時，自動恢複正常，否則必要時可設置系統自動斷電；只有櫃體氣壓滿足規定的氣壓要求時，正壓吹掃控制系統會對櫃體進行有效換氣（1區需置換7倍櫃體自由空間，2區需置換5倍櫃體自由空間），當有效換氣完成後提供信號給櫃體送電。

隨著材料試驗環境日益嚴苛，試驗機本身所面临的技术问题也日益复杂，試驗機本身除需要配套各种环境试验装置及专用设备外，还需要在控制技术、软件技术等方面进行调整适应。正是凭借着深厚的技术积淀，三思泰捷才可适应越来越多此类高端用户的特殊需求。（图为设备在三思泰捷工厂现场）

"And sure," she said, "and I hope that wretched old Feejee won't be in Japan at all, at all, and the horrid haythens won't roast him." THIRD-CLASS PASSENGERS. THIRD-CLASS PASSENGERS. I was about to put a false meaning even on that, when she added "We don't need the ford this time of year; let us ride back as if we gave up the trip--for there may be a vidette looking at us now in the edge of those bushes--and as soon as we get where we can't be seen let us take a circuit. We can cross the creek somewhere above and strike the Wiggins road up in the woods. You can find your way by the blessed stars, can't you--being the angel you are?" "Good-night, gentlemen," said the doctor at last. As he passed into the darkness Quinn bent a mock frown upon his young superior. It would require a mathematical diagram to describe the incident with absolute accuracy. The Curate, of course, had heard nothing about the Clockwork man's other performances; he had scarcely heeded the hints thrown out about the possibility of movement in other dimensions. It seemed to him, in the uncertain light of their surroundings, that the Clockwork man's right arm gradually disappeared into space. There was no arm there at all. Afterwards, he remembered a brief moment when the arm had begun to grow vague and transparent; it was moving very rapidly, in some direction, neither up nor down, nor this way or that, but along some shadowy plane. Then it went into nothing, evaporated from view. And just as suddenly, it swung back into the plane of the curate's vision, and the hand at the end of it grasped a silk hat. Good fitting is often not so much a question of skill as of the standard which a workman has fixed in his mind, and to which all that he does will more or less conform. If this standard is one of exactness and precision, all that is performed, whether it be filing, turning, planing, or drawing, will come to this standard. This faculty of mind can be defined no further than to say that it is an aversion to whatever is imperfect, and a love for what [171] is exact and precise. There is no faculty which has so much to do with success in mechanical pursuits, nor is there any trait more susceptible of cultivation. Methodical exactness, reasoning, and persistence are the powers which lead to proficiency in engineering pursuits. I was the only civilian in that road, and the soldiers, with much curiosity, stared at me. Whenever I noticed an officer, I gave an elaborate military salute, and with such an air that the officers, although hesitating at first, did not fail to return the salute. The reformed system of education was to be not only moral and religious but also severely scientific. The place given to mathematics as the foundation of a right intellectual training is most remarkable, and shows how truly Plato apprehended the conditions under which knowledge is acquired and enlarged. Here, as in other respects, he is, more even than Aristotle, the precursor of Auguste Comte. He arranges the mathematical sciences, so far as they then existed, in their logical order; and his remarks on the most general ideas suggested by astronomy read like a divination of rational mechanics. That a recommendation of such studies should be put into the mouth of Socrates is a striking incongruity. The older Plato grew the farther he seems to have advanced from the humanist to the naturalistic point of view; and, had he been willing to confess it, Hippias and Prodicus were the teachers with whom he finally found himself most in sympathy. We are told that when his end began to approach, the dying philosopher was pressed to choose a successor in the headship of the School. The manner in which he did this is289 characteristic of his singular gentleness and unwillingness to give offence. It was understood that the choice must lie between his two most distinguished pupils, Theophrastus of Lesbos, and Eudêmus of Rhodes. Aristotle asked for specimens of the wine grown in those islands. He first essayed the Rhodian vintage, and praised it highly, but remarked after tasting the other, ‘The Lesbian is sweeter,’ thus revealing his preference for Theophrastus, who accordingly reigned over the Lyceum in his stead.179 Abibulla saw them off with great deference and a contrite air, and watched their retreat; then, as[Pg 260] I was about to send him to despatch the message, he was indignant. The police! What could they do to a sahib like me? It was all very well to frighten poor folks—it was a sin to waste money in asking for a reply which I should never be called upon to show—and so he went on, till I made up my mind to think no more of the matter. And whenever I met the chief at the bazaar or by the Jellum, he only asked after my health and my amusements. Felipa shook her head at Ellton. "Don't get yourself excited about it, Jack dear," she soothed, and Ellton also tried to quiet him. The last straw was laid on when an Indian policeman arrested a young buck for some small offence. The buck tried to run away, and would not halt when he was told to. The chief of police fired and killed a squaw by mistake; and though he was properly sorry for it, and expressed his regret, the relatives and friends of the deceased squaw caught him a few days later, and cutting off his head, kicked it round, as they had seen the White-eye soldier do with his rubber foot-ball. Then they, aroused and afraid too of punishment, fled from the reservation and began to kill. "Yes," he assured her unmoved, "you are. At least you are going to do that, or go to jail." The poor man looked as miserable as if put in a strait-jacket, but tried to literally obey instructions. "Probably it was Corpril Elliott's good management," suggested Gid Mackall, whose hero-worship of Shorty grew apace. "I tell you there aint a trick o' soldierin' that he aint up to." Then suddenly she was silent—and Reuben kissed her. "You finish your tea," he said to George, "and bring some more, Maudie, for these gentlemen," nodding kindly to the two young men, who stared at him as if they thought he had taken leave of his senses.
