In other countries, the medical industry uses oil-free air compressor has been fully implemented to use. Oil-free air compressor for its oil-free, odorless, clean clean features favored. In China, has also been the popularization and development. Oil-free air compressor, ideal for the medical industry to use oil-free compressor Xianyang compressor, its output when the operation is very clean and clean compressed air, used in the medical industry in and will not cause injury to medical staff and patients . Contrary compressor air compressor oil, regardless of the patient's health, sanitation and environmental protection, and for all negative. Oil-free air compressor, very easy to use while maintaining maintenance, oil-free air compressor air compressor oil is relatively more convenient, oil-free compressors in use, maintenance and other aspects than the compressor oil much simple, belong to basic maintenance products. There are oil-free compressors must refuel before use, but also need to price according to the temperature level of the air compressor, frequently change the oil, if forgotten, will result in seizures scrapped the entire machine. Machines in use to a certain period of time there will always be some problems compressor repair, such as screw air compressor head wear this failure is very common, head wear, and the main reason for the abnormal sound with the following points: 1 , Cottle screw compressor work place environment and environmental reasons. When our machines run in harsh environments, such as mining, cement, ceramics and other dirt, sand, long working in this environment, it will cause the nose to wear. 2, the use of low-grade oil or lubricating oil for a long time without replacement. Lubricants equivalent of our human blood, while the machine is running can play a lubricating effect, reducing the friction between the parts and components. Also play a role in cleaning, sealing and cooling. When the purchase of oil, we'd buy genuine original oil use to a certain time for a replacement. 3, mainly the filtering accuracy. Screw air compressor filter aging or because dust blockage occurs. We should promptly clean up and replace the filter, filtering accuracy guarantee. 4, the lack of maintenance of the machine for a long time. Takes a certain amount of maintenance costs, maintenance costs, many companies are considered too expensive to carry out maintenance work without timing it so that some parts work no less frequently, resulting in damage to the host. 5. In order to protect the safety of the plant when the pressure switch is set to make an error or when the air compressor failure, oil barrel higher than the rated pressure relief valve will open when the pressure 0.1Mpa. Oil separator above the minimum pressure at the outlet 6. oil barrel valve opening pressure set about 0.45Mpa. 7. After the cooler has two ways to go cold are: air-cooled and water-cooled, cooled after cooler to reduce the temperature of the compressed air vents to ensure the safe use of compressed air after parameter index meets air handling equipment . 8. After the compressor shut down, the pressure relief valve opens the discharge of oil and gas within the barrel, making the air pressure when the next run empty load operation under no-load conditions and longer start. Screw compressor host equivalent of our heart area, the entire machine is the most important, only to ensure the normal operation of the host, our machine to work properly, bring benefits from our business was. Screw air compressor, air compressor Qin Wei, the technology leader in Europe and America (certified), the compressor is provided by Compressor Co., Ltd., Xianyang Qin Wei. Xianyang Qin Wei Compressor Co. (www.xykyj.cn/) is Xianyang, compression, separation equipment leader, over the years, the company implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs.
