HZ-384A Automatic Oxygen Bomb Calorimeter Calorific Value Testing Equipment
I.Summarize
HZ-384A Automatic Calorific Value Tester is used to measure the calorific value of solid, liquid and other combustible materials (coal, petroleum food, wood, biomass).
The instrument is a new type of energy-saving analysis instrument developed by our company. The calculation program carefully compiled improves the measurement accuracy greatly. Color and touch display,good user interface. The measurement process is automatically controlled to reduce human error. Print cartridge, dry base high position

Common faults and troubleshooting
phenomenon | reason | handle |
1,Oxygen bomb leak | Aging or wear of rubber sealing ring | Replace the sealing ring |
2,Ignition failure | ① The circuit is blocked or the ignition wire is in poor contact ② The sample is wet ③ Poor contact between ignition wire or cotton thread and sample ④ The two electrodes are too dirty ⑤ Oxidation of ignition cap ⑥ The two electrodes are short circuited with the crucible (it is easy to burn the crucible and electrode at this time) | ① Check whether the wiring is well connected, whether the oxygen warhead is in good contact with the ignition cap, and whether the oxygen bomb is placed properly ② The sample is splashed with oxygen too fast ③ Re sample ④ Sand the electrode with sandpaper ⑤ Sand the ignition cap oxide with sandpaper ⑥ Replace the electrode or crucible and re load the sample |
3Incomplete combustion of sample | The sample is not flammable Insufficient oxygen or insufficient oxygen pressure | Wrap the sample with lens wiping paper, extend the oxygen filling time, and replace the oxygen cylinder |
4,After ignition, the temperature rises too high and the calorific value is too high | ① Agitator does not work ② Mixing blade falling off | ① The mixing shaft is stuck and the line is blocked ② Insert a cotton into the nylon rod connected with the mixing shaft and insert it again |
5,The test did not end for a long time | The ambient temperature is too high | Adjust the water temperature of the outer cylinder to the room temperature, or lower the indoor temperature |
6,Air leakage of oxygenator | Aging or wear of sealing ring of oxygenator | Replace the sealing ring |
