Calorimeter routine maintenance and maintenance knowledge

Calorimeter is an instrument for measuring the calorific value of solid and liquid flammable substances. It is widely used in coal, power, metallurgy, chemical industry, building materials, food, quality inspection, education, scientific research and other industries to test the heat of coal, petroleum and other substances. value.

Maintenance and maintenance of calorimeter (fixed temperature barrel) (1) Add 300ml pure water to the inner barrel every week;

(2) It is forbidden to bring foreign matter or impurities into the inner barrel so as not to pollute the water quality and block the pipeline;

(3) After the experiment is completed, the constant temperature lid should be opened to avoid eroding the instrument components;

(4) Replace the outer tub water at least once a year;

(5) Abnormal conditions in the instrument can be diagnosed using an expert diagnostic system.

Maintenance and Maintenance of Calorimeter (Oxygen Bomb) (1) Before the formal experiment every day, be sure to fill the empty oxygen bomb with enough gas and submerge it in water for several minutes to observe whether the sealing function of the oxygen bomb is good and to ensure the reliability of the test results. ;

(2) After each experiment is completed, the parts of the oxygen bomb must be flushed with distilled water and wiped with a special towel;

(3) If a leak of oxygen bomb is found, replace the spare seal; otherwise, it cannot be used;

(4) If it is found that the oxygen bomb thread slides, the use of the oxygen bomb is prohibited;

(5) Oxygen bombs should be inspected on schedule and at least one hydrostatic test per year (sent to Sande for testing);

(6) After use, it should be cleaned. It is best to heat on the electric oven for 3~5 minutes.

(7) Care must be taken when taking oxygen bombs from the inner barrel to prevent damage to the inner barrel due to impact or falling.

Calorimeter (automatic oxygenator) maintenance and maintenance (1) The trial oxygen must meet the requirements of GB213-96, prohibit the use of electrolytic oxygen. Oxygen cylinders should be placed in a place that complies with safety regulations;

(2) The oxygenator should be placed on a stable work surface;

(3) Oxygenators (including oxygenating catheters and pressure reducing valves) must not be in contact with various oils and fats;

(4) The oxygen conduit on the oxygenator should avoid bending and twisting;

(5) No naked flame is allowed near the oxygenator;

(6) If the oxygen pressure of the oxygen cylinder is less than 5 MPa, replace it with new oxygen. If the oxygen pressure in the oxygen bomb exceeds 3 MPa, the oxygen in the oxygen bomb should be released, and the oxygen bomb reloaded and recharged.
