[1] the gas tightness of the gas path decreases:

the indication of the flowmeter should be between 0.8~1.2. If the air tightness decreases, the following components should be checked: air pump, flowmeter, glass tube, rubber tube and air circuit connection

[2] electrolytic cell

1. The air leakage of the electrolytic cell leads to the decrease of the air tightness of the gas path

2. Dirt on the four pole pieces in the electrolytic cell should be cleaned

3. The four pole pieces in the electrolytic cell should be reliably connected with the controller

[3] agitator:

the disappearance of the magnetic force of the mixing rod is a common cause of mixing out of step, which should be replaced

[4] temperature control part

1. A. the temperature always displays 1999 ℃, indicating that the thermocouple circuit is not connected or its internal circuit is open

specific to the medical device industry B. if the temperature has not increased, but there is heating current, it means that the thermocouple is connected reversely

c margin is very small. If the temperature always shows room temperature, it means that the thermocouple wiring is short circuited

2. If the temperature value is less than the set furnace temperature, there should be heating furnace flow. If the furnace flow shows 0.0A, it means that the fuse tube is broken, and the internal circuit of the silicon carbon tube itself is open or the connection is not connected

3. The constant temperature fluctuation is too large, which is generally the reason for the silicon carbon tube. The resistance value should be 73D. The printed object has a smooth and high-quality surface of ~~8 Ω. It is recommended to choose the original accessories of our company

[5] sample sending mechanism

in order to cooperate with the fault diagnosis of the sample sending machine, four indicator lights are provided on the main board of the instrument, and the specific fault can be judged according to the condition of the indicator light

1 23 get rid of the short board of bondage development 4

1: when the motor is moving forward, the indicator light should be on

2: when the motor retreats, the indicator light should be on

3: the indicator light should be on when the sample sending mechanism stays at 500 ℃ or 1050 ℃

4: when the sample sending mechanism is in the original position, the indicator light should be on
