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(cè)試儀器之一，自動(dòng)熱量?jī)x。熱量計(jì)常見(jiàn)問(wèn)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(diǎn)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(diǎn)火裝置是否接觸良好，氧彈內(nèi)筒是否放置正確。樣品潮濕，氧氣飛濺過(guò)快，點(diǎn)火線或棉線與樣品接觸不良。重新加載樣本。如果兩個(gè)電極太臟，用砂紙打磨電極。點(diǎn)燃氧化，用砂紙打磨點(diǎn)燃的氧化物，用坩堝短接兩個(gè)電極（此時(shí)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(zhǎng)充氧時(shí)間，更換氧氣瓶。
4、點(diǎn)火后濕度上升過(guò)高，熱值過(guò)高：攪拌機(jī)不轉(zhuǎn)動(dòng)，攪拌軸卡住，線路堵塞。當(dāng)攪拌葉片落下時(shí)，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(zhǎng)時(shí)間未完成試驗(yàn)，環(huán)境溫度過(guò)高，調(diào)整外缸水溫與室溫基本一致，或降低室內(nèi)溫度。
6、充氧時(shí)滿氧彈泄漏，充氧時(shí)密封圈老化或磨損。更換氧合器的密封圈。
