Tester Operation Process Introduction

1, the sulfur analyzer power is turned on, the instrument automatically warms up, when the temperature rises to 1050 °C, the electrolytic cell pump is stirred open, then the electrolyte is sucked into the electrolytic cell, the flow rate is controlled to 0.8 to 1.2 ml after adjusting the stirring speed, After ensuring that the airway is closed, it can be dismantled. About 50 milligrams of coal is covered with tungsten trioxide (analytically pure) in a porcelain boat and placed in a quartz boat at the mouth of the furnace. Select the sample weight and input the weight value. Press the start button to send the sample. The instrument will send the sample slowly. Furnace body, so that continuously made two or three waste samples, when the sulfur content is counted, the printer automatically prints the results, and the instrument can be used as a formal coal sample.

2. Use a porcelain boat to weigh 50±0.5 milligrams of coal into a quartz boat in the mouth of the furnace. Press the start button to send samples after the sample weight is input. The instrument will send the sample to the furnace slowly. The sulfur content is automatically counted and the experiment is completed. The instrument automatically prints the results.

3. Calibrate the sulfur analyzer Before selecting the coal sample, select the calibration system and input the standard value. At this time, weigh 50±0.5 mg of standard coal, cover the tungsten trioxide and put it into the furnace body. Press the start key after inputting the sample weight. The instrument slowly sends the sample to the furnace and the sulphur content is automatically counted. After the experiment is completed, the instrument automatically prints the result. If the result is not within the range of the standard value error, select the calibration system to enter the selected calibration, press the middle button to display the data has been stored, exit the system calibration, calibration test instrument calibration experiment is over.

Sulfur meter common troubleshooting:

1. After the power is turned on, the sulfur detector alarm will not stop.

Troubleshooting: Open the cover and observe whether the sample is in the original position. If it is not in the original position, it will block the cause of sending the sample block and then turn it on again. After the sample is returned to the original position, the trouble will be eliminated.

If the sample block is in the original position, check whether the original switch is damaged and disconnected from the line.

2. After the power is turned on, does the furnace of the sulfur analyzer heat up?

Troubleshooting: First check whether the controller's major insurance is damaged, replace the insurance after finding out the cause, and then check whether the controller and the furnace body are disconnected, whether the silicon carbon tube is aged and broken, and whether the thermocouple wire is disconnected. Then check if the solid state relay is damaged.

3. When the sample is made, the result is flat and the sample is not baked.

Troubleshooting: check the gas path is normal, the furnace gas outlet stuck, observe whether the flow meter float can be reduced to zero, if not reduced to zero, then check the pipe connection is broken, the piston is loose, the pipeline Whether the glass melting plate in the electrolytic cell is blocked or not, whether the electrolyte should be replaced, and whether the heterogeneous pipe in the furnace body is broken. (If the results are particularly unstable, first make a standard sample. If the standard sample results are normal, then it proves that the coal sample is a special type of coal or the sample preparation is problematic, the sample size of the coal sample does not meet the requirements, or expired coal sample or pollution, etc. Wait).
