Maintenance common sense of household oxygen concentrator

Household oxygen concentrators, like other home appliances, sometimes break down. We need to learn more about the maintenance knowledge of the oxygen concentrator usually. When the oxygen concentrator fails, we will not be in a hurry.

To understand the maintenance knowledge of household oxygen concentrators, we must first know the working principle of the oxygen concentrator. At present, the working principle of oxygen concentrator is physical oxygen production by molecular sieve. The molecular sieve is filled in the adsorption tower, and the molecular sieve is used to increase the pressure to adsorb nitrogen. The oxygen is concentrated and filtered to be high-concentration oxygen, and the nitrogen is discharged when the pressure is decompressed. The two groups of molecular sieves work alternately to continuously produce oxygen.

Generally speaking, you can take the steps of watch, listen, and smell to make a preliminary judgment on which component is wrong. Take corresponding measures according to the specific situation, and troubleshoot.

Watch: Observe whether the indicator lights of the machine are normal, whether the flowmeter displays normal, and whether the filter cotton and the filter element are blocked or falling off.

Listen: Listen to whether the machine has a different sound than usual, whether there is an alarm sound or vibration noise.Find out the faults corresponding to different alarm sounds in combination with the instruction manual.

Smell: Smell the machine for any peculiar smell, especially the smell of burning. Through these smells, you can find out whether the circuit or pipeline of the machine is faulty.

The most common fault is power failure alarm. That's means when the machine is unexpectedly powered off, the machine will alarm. However, most elderly people think that this is a malfunction of the machine. In this case, after turning off the switch of the machine, check whether the power supply is energized. After confirming that there is power, plug in the power supply and turn it on again. The problem will be solved.

Oxygen does not come out, and the flowmeter float does not come up. This is also a common fault. Usually, This is because the oxygen pipe is bent, causing the outflow to be blocked, so that the oxygen cannot come out.

Another situation is that the oxygen outlet of the pipe in the humidification bottle has not been cleaned for a long time, causing blockage.It is necessary to check whether there are any of the above situations, and solve them in a targeted manner.

There is another situation: when the machine is turned on, the power indicator light is on, but the machine is silent and no oxygen comes out. At this time, you need to check the compressor and solenoid valve. Check whether the wires are loose or the pipelines fall off, find the cause of the fault, and then you can solve the problem.

If you lack relevant professional knowledge, please don’t open the machine case yourself, so as not to cause damage to the machine. When you can't solve the problem by yourself, it is better to find a professional manufacturer to repair it, which is more convenient and reliable.
