发布时间：2014-03-25 点击次数：1371次

　　我们介绍过量热仪的基本工作原理及应用特点，知道量热仪在测量固体可燃物或液体可燃物的热量指标方面都有着很大的应用。主要应用在煤炭、冶金、石化、新能源等行业领域中。量热仪在操作使用中，难免会有故障问题的发生。下面，鶴壁市華通分析儀器有限公司技术工作人员量热仪常见的故障现象给大家分析一下，以保证分析数据的准确性。

　　一、點火失敗

　　1、首先檢查保險管，保險的位置通常在機器的後面

　　2、檢查氧彈底下的三個支柱，頂蓋上的點火頭是否生鏽，如生鏽會造成接觸不良，應用砂紙打磨去鏽。

　　3、檢查氧彈內點火絲是否卡緊，棉線是否連接上，氧氣是否沖足，如沒有都會造成點或失敗。

　　二、氧彈漏氣

　　1、主要是檢查密封圈的損壞，機器上一共有四種密封圈。

　　2、化驗人員因向調試安裝人員學習四種密封圈的拆換和位置所在。

　　另外，量熱儀要注意以下方面的維護：

　　1、首先要保護環境的衛生

　　2、要把機器蓋打開，保持機器的幹燥

　　3、在溫度低時，要保持機器內的水不能上凍

　　4、氧彈不做時應打開存放，保持幹燥。

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?" HoME 色色新妈妈电影 ENTER NUMBET 0010aab00.com.cn
