煤炭化验设备该如何进行维修
时间：2024-04-10 阅读：74
Coal testing instruments generally refer to the laboratory instruments and equipment for testing the six major indicators of coal quality. Six indicators: kcal, sulfur, moisture, ash, volatile matter and fixed carbon. Coal testing instrument is the general name of the equipment used for various indicators of coal testing, in which calorimeter and sulfur meter are the necessary experimental instruments and equipment for coal testing indicators. First, let's introduce how to carry out rapid maintenance and troubleshooting when one of the coal testing instruments, the full-automatic calorimeter, breaks down in use?煤炭检测仪器一般是指用于检测煤炭质量六大指标的实验室仪器设备。六项指标：KCl、硫、水分、灰分、挥发物和固定碳。煤炭测试仪器是用于煤炭各项指标测试的设备的总称，其中热量计和硫计是煤炭测试指标所必需的实验仪器和设备。首先，让我们介绍一下当煤炭测试仪器之一全自动热量计在使用中发生故障时，如何进行快速维护和故障排除？
One of the coal testing instruments, automatic calorimeter. Common problems and maintenance methods of calorimeter:
1. Air leakage of oxygen bomb: the rubber sealing ring is aged or worn. Replace the sealing ring at each part of the oxygen bomb.
2. Ignition failure: the circuit is disconnected or the contact is poor. Check whether the wiring is well connected, whether the oxygen warhead is in good contact with the ignition, and whether the inner cylinder of the oxygen bomb is properly placed. The sample is wet, the sample is splashed with oxygen too quickly, and the ignition wire or cotton thread is in poor contact with the sample. Reload the sample. If the two electrodes are too dirty, polish the electrodes with sandpaper. Ignite and oxidize, polish the ignited oxide with sandpaper, short circuit the two electrodes with the crucible (at this time, it is easy to burn the crucible and electrode), replace the electrode or crucible and reload the sample.
3. The sample does not burn, and the sample is not flammable: if the oxygen is insufficient or the oxygen pressure is insufficient, wrap the sample with lens wiping paper to extend the oxygen charging time, and replace the oxygen cylinder.
4. The humidity rises too high after ignition, and the calorific value is too high: the mixer does not rotate, the mixing shaft is stuck, and the line is blocked. When the mixing blade falls, insert a cotton thread into the nylon rod hole connected with the mixing shaft and re insert it.
5. If the test is not completed for a long time and the ambient temperature is too high, adjust the water temperature of the outer cylinder to be basically the same as the room temperature, or reduce the indoor temperature.
6. The full oxygen bomb leaks during oxygen charging, and the sealing ring is aged or worn during oxygen charging. Replace the sealing ring of the oxygenator.
煤炭测试仪器之一，自动热量仪。热量计常见问题及维修方法：
1、氧弹漏气：橡胶密封圈老化或磨损。更换氧弹各部位的密封圈。
2、点火故障：电路断开或接触不良。检查接线是否良好，氧弹头与点火装置是否接触良好，氧弹内筒是否放置正确。样品潮湿，氧气飞溅过快，点火线或棉线与样品接触不良。重新加载样本。如果两个电极太脏，用砂纸打磨电极。点燃氧化，用砂纸打磨点燃的氧化物，用坩埚短接两个电极（此时坩埚和电极容易燃烧），更换电极或坩埚，重新装填样品。
3、样品不燃烧，样品不易燃：如果氧气不足或氧气压力不足，用镜头擦拭纸包裹样品，延长充氧时间，更换氧气瓶。
4、点火后湿度上升过高，热值过高：搅拌机不转动，搅拌轴卡住，线路堵塞。当搅拌叶片落下时，将棉线插入与搅拌轴相连的尼龙杆孔中，然后重新插入。
5、如果长时间未完成试验，环境温度过高，调整外缸水温与室温基本一致，或降低室内温度。
6、充氧时满氧弹泄漏，充氧时密封圈老化或磨损。更换氧合器的密封圈。
