Compared with ordinary air compressors, oil-free air compressors are much more expensive. Most of them are used in the pharmaceutical and food industry. Only without oil in the whole process can ensure the production safety of these products. Oil-free air compressors also require regular maintenance like ordinary air compressors. We need targeted solutions when encountering different problems. Today, I will explain to you the common oil-free air compressor maintenance knowledge.
1. The air compressor cannot work normally, and the air supply is insufficient.
1.1 Insufficient voltage causes the air compressor to not work normally. Generally, when this happens, it will be accompanied by a humming sound when the air compressor starts;
1.2 The leakage of the starting capacitor causes the current to increase after the speed is slowed down, which will cause the air compressor head to heat up too fast, and the air compressor head itself has an automatic protection device. Once the temperature is too high, it will automatically stop, which will also cause The air compressor does not work normally. Generally, in this case, you can directly replace the new accessories, but it should be noted that the UF value must be the same. If it is too large or too small, it will not work normally, and forcible use will cause damage to the equipment.
2. The noise of the air compressor is too loud when running
2.1 First check whether the accessories or parts are loose, if not, check whether the current and voltage are normal during operation;
2.2 When the components, current, and voltage are all normal, we can basically determine that the problem is with the machine head. Generally, only the machine head can be replaced at this time. The accuracy of oil-free air compressors is much higher than that of ordinary air compressors, so there are higher requirements for the use environment. When installing and using, you should try to avoid places with large dust, and regularly power off for large cleaning to ensure no oil. Cleanliness inside and outside of the air compressor.
2.3 When the motor bearings and leather cups are worn out excessively, it will also cause the air compressor to run too loudly. At this time, it is necessary to replace the relevant accessories.
3. Improper setting of the air compressor causes the equipment to not operate normally
3.1 The storage battery of the air compressor must be set to 0 before starting the operation. If the air compressor head rotates too slowly and makes a humming sound, it is usually because the one-way valve is blocked by impurities and cannot work normally. , because its working purpose is to fill the gas into the gas cylinder, if the main film is stuck by a foreign body, it will cause reverse gas leakage.
3.2 After the air compressor fails to start for the first time, it still fails to start when it is started for the second time. At this time, it can be considered whether there is a foreign body stuck and the check valve cannot work normally. When this happens, we can use a wrench to open the check valve. After cleaning.
The above are some daily troubleshooting methods for oil-free air compressors. Many other faults need to be eliminated according to the actual use. Dehaha recommends that the maintenance of the air compressor be handed over to professionals for operation. Improper maintenance operations may cause air compressor damage. The machine is damaged twice.
