Main technical features

1. Powerful test software: built-in three-stage fixed coal test program: moisture, ash, volatile matter, national standard method, fast method, repeated inspection and burning flexible setting, can immediately restore the test function after power failure.

2. The two hosts work in parallel or separately. After the sample is placed, the instrument automatically completes the test and calculates the results. The whole process is unattended and the furnace cover of the instrument is automatically switched on and off. There is no need to replace the crucible or uncover the crucible in the middle. When the sample volume is small, it can work alone, saving time, effort and power.

3. Interface mode: using network bus technology, the system has strong anti-interference ability and expandable ability.

4. The real-time display function of weighing is convenient for users to weigh accurately and effectively.

5. Imported slide rail sample delivery mechanism, smooth operation, low noise. Weighing and sample delivery speed, shorten the overall experiment time.

6. Fast test speed: the test can be carried out after starting up. It adopts multi-furnace double balance structure, fast and stable balance structure, and has a constant temperature drying device.

7, water ash equipment air supply components: the use of internal air circulation device without oxygen or compressed air.

8. Control mode: upper and lower computer control. Using 32-bit CPU high integration technology and efficient control. Fault alarm self-protection. Using high-precision infrared indexing coding disc positioning, the ultimate precise position control.

9. The water ash equipment adopts the electric push rod mode to automatically open and close the furnace door to avoid the damage to the furnace body caused by the sudden cooling and heat.

10. The volatile matter equipment adopts double guide rail translation technology to ensure the docking between each two samples and the furnace. Standard crucible is used without manual participation or nitrogen flow.

11. Stepper motor positioning method: precision stepper motor positioning method is adopted, which does not need to be coaxial and is not affected by dust. The positioning accuracy is high, and the stability and precision are much higher than the traditional photoelectric positioning. The perfect solution to the problem of high failure rate of photoelectric positioning.

12, analysis and testing system: can be connected to the company's most coal quality analysis equipment. Can automatically upload data, production reports. (Users can design reports according to their own needs).

Accurate and reliable data

1, the use of automatic thermal weight analysis, the balance records the original data for calculation.

2. The unique structure design is adopted, the high and low temperature partition is adopted, and the temperature rise of the control part does not exceed 35 degrees during the experiment.

3. Classic slow ash can be used for each ash test, which fully meets the national standard requirement that the furnace temperature rises to 500 ℃ within not less than 30Min, thus ensuring the accuracy of ash test.

4. The furnace adopts corrosion-resistant design and is not afraid of corrosive samples.

5. The structure is simple and reasonable, there is no "manipulator" and other slide rail sample feeding devices, there is no need to frequently move the crucible from the sample weighing plate to the combustion plate, and there will be no mechanical failures such as dropping the crucible during the transfer process.
