2022-12-25 来自: 鹤壁市淇天仪器仪表有限公司. 浏览次数:449
微机全自动量热仪主要由恒温式弹桶量热仪及微型计算机等部分组成，是一种由计算机软件控制,并能进行对其数据处理的多功能、自动化热量测试仪器。该仪器具有测量精度高、操作简便、使用可靠、外观精美等特点，主要用于煤炭、生物质颗粒、石油、建筑材料、固体/危废物、木材、zhayao等可燃物质发热量的测定。
Microcomputer automatic calorimeter mainly consisting of thermostatic Shell calorimeter and microcomputer etc is a kind of versatile and automated heating testing instrument controlled by computer software and capable of data processing. The instrument features in accuracy, easiness to operate, reliability and attractive appearance and so on which is widely used in determination of calorific value of combustible substances such as coal, petroleum, chemical, food, timber as well as explosives and so on.
实验步骤Experimental procedure
1. 测试发热量：Testing heat value
（1）开机步骤：Procedure of turning on the computer
把量热仪和制冷机电源插头插到电源上，打开量热仪电源开关，“双击”电脑桌面上的“微机全自动量热仪”快捷方式。图（1） “点击”图（2）出现图（3）“点击”确定，进入量热仪操作界面“图4”。
Plug the calorimeter and refrigerator power into the socket, turn on the power of calorimeter, and “double-click” the shortcut of “Microcomputer automatic calorimeter” on the desktop. Figure (1) “Click” Figure (2) to witness Figure (3) and then click “enter” to enter user interface of the calorimeter "Fig4."
（2）发热量操作：
在坩埚内称取（小于0.2mm）0.9-1.1g 分析试样。将点火丝分别接在氧弹两支电极柱上，如不加棉线，点火丝要与试样保持良好接触，并注意勿使点火丝接触坩埚。向氧弹内加入10ml蒸馏水，旋紧氧弹盖，轻轻放在冲氧仪上，氧气压力调整到2.8-3.0Mpa，充15-30S,（时间不得小于15S）将氧弹放入内筒中，盖上量热仪上盖，点击 图(4)“开始”按钮，系统开始测试 图(5)，在实验过程中输入样重；硫；氢；水，点火热等数据，测试结束后软件自动计算出结果并在屏幕上显示出来。图（6）(2)
Heat operation:
Take (less than 0.2mm) 0.9-1.1g sample from the crucible for analysis. Connect the ignition wires to two electrodes column of oxygen bomb respectively, if without cotton, the ignition wire should stay a good contact with the sample and should get touch with the crucible. Then add 10ml of distilled water into the Oxygen bomb tighten the cover and gently place it on Oxygen meter, adjust oxygen pressure to 2.8-3.0Mpa for 15-30S, (no less than 15S). Put oxygen bomb into the barrel, cover calorimeter lid, click figure (4) "Start" button, then the system begins the test figure(5), During the experiment; input sample weight, sulfur; hydrogen; water, ignition and so on so that software can automatically calculate the results and display them on the screen after test is completed.
