A calorimeter is an instrument used to measure the calorific value of a sudden chemical or physical reaction process. The structure of calorimeter generally has four parts: outer cylinder, inner cylinder, thermometer and stirrer. The outer barrel of the calorimeter is used for insulation and the inner barrel is used to act as a reaction vessel. The calorimeter's thermometer is used to measure changes in the reaction temperature, while the stirrer is used to evenly mix the reactants to improve the reaction's completeness and accuracy of the calorimeter. Calorimeters are widely used in wood, petroleum, coal and other industries.
When using a calorimeter, the indoor environment needs to meet certain conditions. First, the room where the calorimeter is used must be dedicated and no other tests can be performed indoors. Second, curtains are needed in the calorimeter's dedicated room to avoid direct sunlight and affect the measurement results. Third, the temperature difference between the different time and season in the calorimeter special room should not be too large. Therefore, the calorimeter special room should be equipped with air conditioning as much as possible. Fourth, when using a calorimeter, strong ventilation and heat radiation should be avoided indoors so that the indoor temperature is relatively constant.
Calorimeters are sophisticated instruments that require frequent maintenance to ensure the accuracy of calorimeter measurements. One of the most important aspects of calorimeter maintenance is the maintenance of oxygen bombs. In addition to using the calorimeter to clean and dry the oxygen bomb, the user must also clean the oxygen cap of the oxygen bomb, the ash analyzer gel seat, the bullet cup and other parts, and check whether there is any machinery. damage. The calorimeter's oxygen bomb can only be twisted by hand. If it feels resistance, it should be stopped. Never use tools to tighten it. In addition to maintaining oxygen bombs, the calorimeter maintenance should also note the use of calorimeter water. The water used by the calorimeter is preferably pure water, and the water inside the calorimeter should be discharged after each use of the calorimeter.
