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.
煤炭測試儀器之一，自動熱量儀。熱量計常見問題及維修方法：
1、氧彈漏氣：橡膠密封圈老化或磨損。更換氧彈各部位的密封圈。
2、點火故障：電路斷開或接觸不良。檢查接線是否良好，氧彈頭與點火裝置是否接觸良好，氧彈內筒是否放置正確。樣品潮濕，氧氣飛濺過快，點火線或棉線與樣品接觸不良。重新加載樣本。如果兩個電極太臟，用砂紙打磨電極。點燃氧化，用砂紙打磨點燃的氧化物，用坩堝短接兩個電極（此時坩堝和電極容易燃燒），更換電極或坩堝，重新裝填樣品。
3、樣品不燃燒，樣品不易燃：如果氧氣不足或氧氣壓力不足，用鏡頭擦拭紙包裹樣品，延長充氧時間，更換氧氣瓶。
4、點火后濕度上升過高，熱值過高：攪拌機不轉動，攪拌軸卡住，線路堵塞。當攪拌葉片落下時，將棉線插入與攪拌軸相連的尼龍桿孔中，然后重新插入。
5、如果長時間未完成試驗，環境溫度過高，調整外缸水溫與室溫基本一致，或降低室內溫度。
6、充氧時滿氧彈泄漏，充氧時密封圈老化或磨損。更換氧合器的密封圈。
