Common Faults and Causes of Using Calorimeter

Rinse the cup, clean the threads, and inspect the cup for mechanical damage. Be careful not to invert the cup. Check the seal ring for wear and damage during combustion. If there is a leak in the seal, replace it. Check whether the insulation pad and insulation cover are good or not, and check the insulation performance regularly. Periodically conduct a 20.0Mpa hydrostatic test on the oxygen bomb after each hydrostatic test.

Calorimeters should be frequently inspected and maintained every day after the end of the test, so that the instrument can always maintain a good working condition and can prolong its service life1.

Oxygen Bombs: In addition to cleaning and drying oxygen bombs after each test, attention should also be paid to the following points:

(1) The oxygen bomb can only be twisted by hand. When the hand feels resistance, it should be stopped. Never try to use the tool to tighten it. After the test is completed, it should be cleaned once.

(2), bomb caps and valve seats should be flushed and wiped dry after use.

(3) Rinse the cup, scrub the threads, and inspect the cup for mechanical damage. Be careful not to invert the cup.

(4) Check whether the seal ring is worn out and damaged during combustion. If there is a leak in the sealed seal, replace it.

(5) Check whether the insulation pad and insulation cover are good or not, and check the insulation performance regularly.

(6) Regularly perform 20 oxygen bombs.

0Mpa water pressure test, after each hydrostatic test, the use of oxygen bombs must not exceed one year (or not exceed 5000 tests).

2. Heater tube: After the test, the water in the tube should be discharged to the outer tube, wiped dry and kept clean.

3, test water: It is best to be pure water, and to be regularly replaced to ensure the test reliability and success rate.

Note: In order to use the calorimeter safely, the computer equipment must be reliably grounded.
