ZDHW-8Z fully automatic touch calorimeter for power plant testing equipment

Product Features

1. Controlled by a microcontroller, the entire structure is controlled using a 7-inch high-sensitivity touch screen, which is easy and fast to operate. It is specifically designed to measure the heat generation of coal, heavy oil, petroleum coke, and other combustible substances, as well as the total energy of feed and the thermal energy of biomass fuel. Imported electronic chips are used, and the system is stable and reliable with human-machine interaction, making it easy to learn.

2. Highly automated, automatic ignition, automatic injection and drainage, automatic control of water volume in the inner bucket, automatic control of temperature difference between the inner and outer buckets of the instrument, and automatic completion of the entire testing process. Just install the oxygen bomb, and the instrument can complete all the testing work.

3. Automatically calculate and convert the high and low levels of heat generation, automatically save and print the results.

4. Low failure rate, self-protection, self diagnosis, fast fault finding, and easy maintenance.

5. Easy to use, user-friendly interface, good software fault tolerance, easy to learn and use.

6. The measurement results are accurate, using * * cooling correction system, water circulation system, software automatic and error correction system, * * foam insulation technology, and not affected by external temperature during the experimental process. The experimental process is automatically cooled, the calibration environment temperature is relaxed, and the accuracy is better than the national standard.

7. The internal cylinder of the calorimeter device adopts electric stirring with sheet-like blades, and the external cylinder adopts submersible electric stirring, making the stirring more uniform and convenient. The instrument adopts a fused cotton thread ignition method.

8. The test is accurate and the testing precision meets the requirements of the national standard GB/T213-2008 "Method for determination of calorific value of coal".

ZDHW-8Z fully automatic touch calorimeter for power plant testing equipmentthe structure of

The calorimeter system consists of a printer, computer, inner cylinder, oxygen bomb, temperature sensor, mixer, ignition device, outer cylinder, temperature measurement and control system, and water. The main unit of a microcomputer fully automatic calorimeter generally consists of a casing, an inner cylinder, an outer cylinder, a stirrer, a backup water tank, a control circuit, a temperature sensor, an ignition electrode, a water circulation system, etc.

Some fully automatic microcontrollers also have an outer tube temperature control system and an outer tube water temperature control system, which can keep the temperature of the entire calorimeter system and the outer tube water temperature fluctuating within a very small range.

ZDHW-8Z fully automatic touch calorimeter for power plant testing equipmentPrecautions for use:

After each experiment, the following checks and maintenance should be carried out regularly to keep the instrument in good working condition and extend its service life.

1. Oxygen bomb: In addition to cleaning and drying the oxygen bomb after each test, the following points should also be noted and checked:

(1) Oxygen bombs can only be twisted by hand, and should be stopped when tightened by hand. Do not use tools to forcefully twist them. After the test is completed every day, they should be cleaned once.

(2) The spring cap and valve seat should be rinsed clean and wiped dry after use.

(3) Rinse the cup thoroughly, clean the threads, and inspect the upper part of the cup for mechanical damage. Be careful not to invert the cup.

(4) Check for wear and burn damage to the sealing ring. If there is air leakage due to poor sealing, it should be replaced.

(5) Check if the insulation sleeve is in good condition and if there is any damage.

(6) Regularly conduct a water pressure test of 20.0Mpa on the oxygen bomb. After each water pressure test, the usage time of the oxygen bomb shall not exceed one year (or 5000 tests).

2. Coat water cylinder: If the test is not conducted continuously, the water in the cylinder should be drained to keep the interior clean and prevent dirt from falling into the cylinder.
