8 common faults and solutions of N95 mask machine

In the process of using, if there are some faults in the N95 mask machine, how should we do some emergency treatment? The premise is that we must understand clearly what kind of failures generally occur in the N95 mask machine. If these faults are within our control, we The following measures can be taken, and everyone can check in according to the situation they usually encounter.

1. Turn on the power switch of the N95 mask machine, the ultrasonic power indicator of the mask machine does not light up, and there is no action

cause of issue:

1. Poor contact between the power cord of the mask machine and the power socket;

2. The power fuse of the mask machine burned.

2. Turn on the power switch of the N95 mask machine, the power indicator light is on, but there is no action. Press the mask machine ultrasonic test button to have ultrasonic output

cause of issue:

1. The five-core wire connecting the base of the mask machine and the frame is open;

2. The circuit board of the machine program is defective.

3. Turn on the power switch of the N95 mask machine. The power indicator of the mask machine is on, but there is no action. Press the ultrasonic test button of the mask machine and there is no ultrasonic output.

cause of issue:

1. Check if the emergency stop switch of the mask machine is pressed;

2. The 110V or 24V power supply of the ultrasonic power transformer of the mask machine is abnormal;

3. The circuit board of the machine program is defective.

4. The N95 mask machine works, but there is no ultrasound output when the ultrasound test button and the operation button of the mask machine are pressed.

cause of issue:

1. The 110V power supply of the ultrasonic power transformer of the mask machine is abnormal;

2. The 110V power cord of the main board of the ultrasonic circuit of the mask machine dropped.

5. Press the test button N95 mask function to work normally, but press the mask machine operation button but the machine does not work

cause of issue:

1. The operation switch of the mask machine is damaged;

2. The five-core wire connecting the base of the mask machine to the frame is open.

6. When pressing the N95 mask machine ultrasonic test button, the indicated value of the power load meter is greater than 20% and cannot be adjusted down through the tuner

cause of issue:
