Oil-free air compressor is a kind of high performance and high reliability equipment, which is widely used in pharmaceutical, food processing, electronics, chemical and other industries. However, as a mechanical and electrical equipment, oil-free air compressor will inevitably appear in the use of some common problems, such as excessive noise, pressure instability, gas flow decline and so on. For these problems, some can be solved through daily maintenance and adjustment, and some need more specific maintenance treatment. This article is to introduce the common problems and maintenance methods of oil-free air compressors in detail, so that you can solve the problem easily and effectively.
1. Excessive noise
When the oil-free air compressor is working, the work of the cylinder and exhaust valve will produce a certain noise, which is a normal phenomenon, but if the noise is too large, it is necessary to check whether the following possible reasons exist:
1. The belt of the air compressor is slack or worn, and the solution is to adjust or replace the belt.
2. The air valve or transmission parts in the compressor are seriously worn, and it is necessary to re-run or replace the air valve and transmission parts.
3. The oil cooler has serious dust accumulation and poor oil cooling, so it is necessary to clean the oil cooler.
4. The air filter element is seriously polluted, and it is necessary to replace the air filter element.
Second, the pressure is unstable

Pressure instability can be caused by several problems:
1. The air filter element is seriously polluted, resulting in unstable gas flow, and it is necessary to clean or replace the air filter element.
2. Exhaust valve wear or poor lubrication, resulting in reduced exhaust volume, then need to adjust the lubrication or replace the exhaust valve.
3. If the exhaust pipe leaks, reseal or replace the exhaust pipe.
4. The piston or cylinder is seriously worn, and the badly worn parts need to be replaced.
Third, the gas flow decreased
The gas flow rate will also be affected by some factors that will lead to a decrease in the gas flow rate:
1. The air filter element is seriously polluted, and it is necessary to clean or replace the air filter element.
2. Exhaust valve wear or poor lubrication, resulting in reduced exhaust volume, then need to adjust the lubrication or replace the exhaust valve.
3. The piston or cylinder is seriously worn, and the badly worn parts need to be replaced.
4. The operation time of the air compressor is too long, then it is necessary to check the balance performance and carry out the necessary maintenance.
Four, the motor can not start
If the motor does not start, it may be caused by the following problems:
1. If the power supply is faulty, check the circuit and repair the power supply.
2. The overload protection switch automatically trips, and it is necessary to adjust or correct the overload protection switch.
3. If the capacitor is faulty, replace the capacitor or repair the capacitor.
4. The trigger is faulty. Replace the trigger or repair the electrical parts.
5, insufficient oil or quality deterioration
The use of oil-free air compressor needs to be equipped with lubricating oil, if the oil is insufficient or the quality is deteriorated, it will lead to faster wear of mechanical parts, affecting the overall performance of the equipment. Therefore, it is necessary to check and replace or fill the lubricating oil regularly.
6. Other common problems
In the process of using oil-free air compressors, there are other common problems to pay attention to:
1. The vibration of the equipment is too large, which may be due to the loosening of the foundation or the installation of the equipment is not firm, and it is necessary to reinstall the equipment and strengthen the fixing of the foundation.
2. The pressure gauge is not accurate, which may be due to the quality of the pointer of the pressure gauge or the connection of the pressure gauge. At this time, the pressure gauge needs to be replaced or reconnected.
3. The oil level gauge is not accurate, then it is necessary to adjust or replace the oil level gauge.
In SUMMARY:
The above are some common faults that may occur in oil-free air compressors and their maintenance methods and solutions. We can take appropriate maintenance measures to solve the problem according to the characteristics of the fault and ensure the long-term stable operation of the equipment. Of course, the usual daily maintenance is also very important, maintenance, we need to strictly in accordance with the equipment manual maintenance provisions for cleaning and replacement of lubricating oil and other work. These measures can ensure the healthy operation of our equipment, improve production efficiency and the service life of the equipment.
