智能測硫儀在實驗室的應用

发布时间：2012-03-24 点击次数：1117次

硫是煤炭中的有害元素之一，硫分的高低直接影響到煤的使用價若動力用煤，硫分過高會汙染環境，腐蝕管道；冶煉用煤，硫分過，高會直接影響生鐵質量。在煤炭銷售中，空氣幹燥基全硫被作爲商品煤計價的一。爲了能更快速准確地測定全硫，煤礦購置了一體化精密智能汕硫儀，操作人員必須對該測定儀有個全面的了解，學會對常見故障的的判斷及處理。

使用過程中的常見故障及解決辦法：測定結果不穩定，忽高忽低

1、首先檢查系統是否漏氣。其方法是用手捏緊電解池上方通往幹燥管的乳膠管，觀察流量計中氣體流是否爲零，若爲零，則證明此處管路不漏氣，若氣體流量不爲零，則說明此處管路漏氣，應及時更換乳管與幹燥管路相接觸的密封圈。然後，再用手捏緊煤灰過濾器通往電解池的乳膠管，若氣流爲零，則說明電解池不漏氣；反之，說明電解池漏氣。最後檢查過濾器與二分閥之間二分閥通往高溫爐之間的管路是否完好。

2、送樣是否到位。檢查異徑管內是否有異物，送樣機構聲音是否異常，若存在上述現象，應及時處理。

3、氣泵是否完好。打開氣泵，調節流量計的閥門，觀察流量計的示數是否有變化，若有變化，則說明氣泵完好無損失；否則，說明氣泵已壞，應及時更換氣泵。

The great ship steamed onward, day after day and night after night. There was no storm to break the monotony; no sail showed itself on the horizon; no one left the steamer, and no new-comers appeared; nobody saw fit to quarrel with any one else; and there was not a passenger who showed a disposition to quarrel with his surroundings. Stories were told and songs were sung, to while away the time; and, finally, on the twentieth day, the captain announced that they were approaching land, and the voyage would soon be over. "I could go on with a long account of the tortures in China, but they are not very pleasant reading, and, besides, some of them are too horrible for belief. I will stop with the torture known as 'the hot-water snake,' which consists of a coil of thin tubing of tin or pewter in the form of a serpent. One of these coils is twisted around each arm of the victim, and another around his body, in such a way that the head of the snake is higher than any other part. Then they pour boiling water into the mouth of the snake, and the flesh of the prisoner is burned and scalded in the most terrible manner. This punishment is said to be used rarely, and only[Pg 374] on persons accused of crimes against the government. It is too horrible to be popular, even among the most cold-blooded people in the world. "No, Lieutenant, she nearly cried. Oh, I wish we were on some dangerous errand to-night, instead of just camp and bed!" One glance at the dim mirror and Leona Lalage flew down the corridor. The music of the band was like the sound of mocking demons in her ears. As she flew up the stairs she could see the blank windows of the Corner House staring dreadfully in. Then she locked the door behind her and flung herself headlong down on the bed. . . . Surely they were a long time getting that hot water. In such a case as this hurry was everything. Bruce crept from the room and looked over the banisters. The whole place was in darkness! "Just a moment," Leona said eagerly. "Suppose I deny that. How are you going to prove that I did so?" It was weary work sitting there and pretending to drink, but patience has its reward at last. Gradually the shy swindlers became accustomed to the seedy shop assistant, who even went out of his way to give them hints as to credulous firms. It seemed to Prout that he knew all the gang at last save one. 162 "I told you to go," she repeated, raising her brows. "Come here, Shorty, you dirty little rascal," said the Deacon, assuming a severely maternal tone, at which Si laughed feebly but cheerily, "and let me wash your face and comb your hair." a-courtin', as you will know if ever you was a widower, and he "Could the gunner knock a man's head off, or one of his legs, just as he pleased?" "But—" "You can't go by yourself—he wudn't like it." "Not if we stick to the farm. Did you notice that ring on his little finger?" "Can't you mortgage?"
