How to deal with common failures of automatic calorimeter

All instruments will have certain failures in the process of use, and the automatic calorimeter is no exception. The automatic calorimeter will also have certain failures in the process of use, and the solution is the most important after the failure. Today, based on the use experience, the editor summarized several common faults in the use of automatic calorimeters, and all the instruments of the solution party will have certain failures in the process of use, and the automatic calorimeters are no exception. The automatic calorimeter will also have certain failures in the process of use, and the solution is the most important after the failure. Today, based on the experience, the editor summarized several common faults and solutions in the use of automatic calorimeters. Let’s take a look.　　 1. The oxygen bomb is leaking. The rubber sealing ring is aging or worn, replace the sealing ring of each part of the oxygen bomb.　　2. Ignition failed. The wiring is blocked or the contact is poor. Check whether the wiring is well connected, whether the oxygen bomb head is in good contact with the ignition cap, and whether the inner cylinder of the oxygen bomb is properly placed. If the sample is wet, oxygenation is too fast to splash the sample, the ignition wire or cotton thread is in poor contact with the sample, reload the sample. The two electrodes are dirty. Use sandpaper to polish the electrodes. The ignition cap is oxidized. Use sandpaper to polish the oxide of the ignition cap. The two electrodes and the crucible are short-circuited (the crucible and the electrode are easily burned at this time). Replace the electrode or reload the crucible.　　 3. The sample burns incompletely, and the sample is not flammable. If the oxygen is insufficient or the oxygen pressure is insufficient, wrap the sample with lens cleaning paper to extend the oxygenation time and replace the oxygen cylinder.　　4. The humidity rises too high after ignition, and the heating value is too high. The stirrer does not rotate, the stirring 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 reinsert it.　　 5. The test does not end 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 lower the indoor temperature.　　6. u200bu200bAir leaks during oxygenation, and the sealing ring is aging or worn during oxygenation. Replace the sealing ring of the oxygen meter. I hope these can help you, welcome to our company's official website: www.51gk.com
