Calorimeters are also called calorimeters or calorimeters. They are mainly used to measure the calorific value of solid combustibles such as coal, coke and vermiculite to measure the quality of the measured object. Widely used in electric power, coal, metallurgy, petrochemical, quality inspection, environmental protection and other industries.
Performance characteristics: single-chip control, using liquid crystal display, intuitive display, easy to operate. With a printer, the results of the experiment are clear at a glance. Automatic mixing, ignition, data acquisition, and storage. The temperature-time curve is displayed in real time. The ignition circuit is automatically judged to be on and off. And there is a fault display alarm function.
Operation method 1. Check the temperature of the inner cylinder to check whether there is any foreign matter in the inner cylinder. Whether all the inlet and outlet of the water pump are inserted into the position, whether there is deformation or folding, whether the water discharge cap is tightened, and whether the overflow opening is open. After the inspection is correct, the measurement and control software is run. The system automatically detects the water level or manually performs the expert diagnosis system. According to the system prompt, add distilled water or deionized water, and automatically fill the outer cylinder through the inner cylinder until the system prompts “the water level is suitableâ€. After the water is added, click on the temperature balance and experiment with the temperature balance.
2. Installation of the oxygen bomb 1) Hang the oxygen warhead on the oxygen bomb bracket.
2) Place the crucible containing the sample on the crucible holder of the oxygen bomb.
3) Connect the ignition wire to the å©åŸš bracket and tighten the nut to control the distance between the ignition wire and the sample according to GB/T213.
4) Carefully place the oxygen warhead into an oxygen cartridge containing 10 mL of distilled water, rotate the oxygen warhead and place it on the oxygenator to oxygenate.
5) After the test is completed, use the bleed valve to release the residual gas in the oxygen bomb, then clean the cartridge and the bullet and dry it.
3. Installation of automatic oxygenator 1) Before installation, carefully check whether the components are tight and the appearance is damaged or damaged.
2) Connect the oxygenator to the oxygen pressure reducing valve with an oxygenation tube and tighten all nuts.
3) Open the main valve of the oxygen cylinder and adjust the pressure reducing valve so that the barometer shows 2.8-3.0 MPa. At this time, the entire gas path should be free of air leakage; otherwise, it should be checked until it is normal.
4) Conduct the oxygenation experiment. At this time, it should be airtight and free to operate. The pressure gauge on the oxygenator should be consistent with the pressure on the pressure relief valve.
5) Open the total valve of the oxygen cylinder (the pressure inside the bottle should be greater than 5 MPa), place the oxygen bomb on the positioning seat of the oxygenator, align the oxygen warhead with the oxygenator nozzle, and press the oxygen handle down, at 2.8-3.0 Oxygen is charged for 30 to 40 s under MPa pressure; then slowly fly and loosen the handle; take out the oxygen bomb.
Online test
After the hardware and software are installed, the system can be tested online. If there is no abnormality, it is considered to be installed; otherwise, it should be re-checked.
<br> <br> the balance balance line connected to the signal line access to a computer serial port. Enter the system and set the “balance type, communication interfaceâ€. After the temperature is balanced, enter “balance†under “Parameter input†to see the current balance weighing data.
Calorific value determination
Put the sample into the oxygen bomb, connect the ignition wire, and flush in the oxygen; place the oxygen bomb into the calorimeter, then input the test parameters, and the system automatically enters the test state. When the sample is tested, select “View Data†to display the current, day and repeat sample results.
