Oil calorific value detection instrument is a relatively important instrument in petroleum instruments and equipment. Then, if there is a failure in use, how to quickly repair and troubleshoot it? Common problems and maintenance methods of oil heating value detection instruments
1. Oxygen bomb leaks from oil heating value detection instrument. The rubber seals are aging or worn. Replace the seals on all parts of the oxygen bomb.
2. The ignition of the oil heating value detection instrument failed. The line is not connected or the contact is bad. Check whether the connection is good, whether the oxygen bomb head is in good contact with the ignition cap, and whether the oxygen bomb inner tube is placed properly. The sample is wet, splashed with too much oxygen, and the ignition wire or cotton thread did not make good contact with the sample. Reload the sample. The two electrodes are too dirty. Sand the electrodes with sandpaper. The ignition cap is oxidized, and the ignition cap oxide is polished with sandpaper. The two electrodes are short-circuited to the crucible (it is easy to burn the crucible and the electrode at this time). Replace the electrode or the crucible and reload the sample.
3. The sample of the oil heating value detection instrument does not burn completely and the sample is not flammable. Insufficient oxygen or insufficient oxygen pressure, wrap the sample with lens cleaning paper to extend the oxygenation time, and replace the oxygen bottle.

4, the oil heat value detection instrument after the humidity rises too high, the heat value is too high. The mixer does not turn, the mixing shaft is stuck, and the line is blocked. When the stirring blade falls, use a cotton thread to insert it into the nylon rod hole connected to the stirring shaft and reinsert it.
5. The test of the oil heating value detection instrument is not finished for a long time, the ambient temperature is too high, and the water temperature of the outer cylinder is basically the same as the room temperature, or the indoor temperature is reduced.
6. Oil calorific value detection instrument Leaks during oxygen bomb oxygenation. The seal ring is aging or worn during oxygenation. Replace the oxygenator seal ring.
