Oil-free air compressor is a sanitary type of air compressor, its working principle is to produce high pressure gas through air compression, without the use of oil lubrication. It is widely used in various industries, such as pharmaceutical, food, electronics, textile, etc., with high efficiency, reliable, energy saving characteristics.
In order to ensure the normal operation of oil-free air compressors, the protection function is very important. Some common protection functions are described below.
1. Overload protection: When the load of oil-free air compressor exceeds the rated working range, the overload protection system will automatically start to prevent the equipment from overheating or damage.
2. Temperature protection: The temperature protection system of oil-free air compressor can monitor the temperature change of the equipment. When the temperature exceeds the set threshold, the system will automatically shut down to prevent the device from overheating.
3. Pressure protection: The pressure protection system of oil-free air compressor can monitor the pressure change of the equipment. When the pressure exceeds the set threshold, the system automatically shuts down to prevent the pressure from getting too high.
4. Oil leakage protection: Since oil-free air compressor does not use oil lubrication, once oil leakage occurs, the system will automatically stop to avoid environmental pollution and equipment damage.
5. Filter blockage protection: The filter of oil-free air compressor is used to remove impurities and pollutants in the air. If the filter is blocked, the system automatically shuts down to avoid air quality degradation and equipment damage.
6. Electrical system protection: The electrical system protection function of oil-free air compressor can monitor current and voltage changes. Once the current or voltage is abnormal, the system will automatically shut down to prevent equipment failure and personal stability accidents.
7. Running time protection: The running time protection function of oil-free air compressor can record the running time of the equipment. Once the set running time limit is reached, the system will automatically stop to prevent the equipment from running continuously for a long time and cause damage.
8. Automatic drainage function: The automatic drainage function of oil-free air compressor can automatically remove water and pollutants in the air. This maintains air quality and prevents damage to equipment.
In summary, the protection function of oil-free air compressors is very important for the normal operation and extended service life of the equipment. These protection functions can monitor and control various parameters of the equipment, and in the event of abnormal conditions, the system will automatically shut down to protect the safety of equipment and personnel. Therefore, when selecting an oil-free air compressor, the protection function is one of the important factors to be considered.
