Generally speaking, oil-free air compressors do not contain oil at all. Truly oil-free is the all-oil-free air compressor. The air compressor lubricated with water is the real oil-free air compressor. Generally speaking, the oil content of oil-free air compressors is very small. So, what is the difference between an oil-free air compressor and an oil-free air compressor? The following Copco has sorted out the relevant content to share with you.
Oil free air compressor with oil air compressor difference:
1. Different materials: The oil-free air compressor itself does not contain oily substances, which avoids the pollution of the oil machine to the terminal equipment. The material of the oil air compressor itself contains oily substances, which will pollute the terminal equipment.
2. The service life is different: the oil-free air compressor adopts a heat-resistant piston, so that the bearing grease is no longer lost due to high temperature conduction and radiation, which greatly extends the service life of the oil-free air compressor. The oil air compressor has no heat resistance piston, and the sealing grease is easily lost, resulting in dry wear damage to the bearing and short life of the oil air compressor.
3. The working principle is different: the oil-free air compressor has no oil during operation. Whether it is an oil-free piston machine or an oil-free screw machine, a large amount of high temperature will be generated during operation. If air compressor oil is involved, the high temperature generated during the compression process of the air compressor will be taken away, thereby cooling the machinery.
4. The exhaust is different: the oil-air compressor is lubricated with resin material, and the final exhaust does not contain oil. The oil-air compressor is oil-lubricated, so the final exhaust contains oil.
The pressure range of compressed air varies with application scenarios and equipment requirements, generally between 0.2 and 1.6MPa(2 to 16bar). The following is the specific pressure analysis under different scenarios: 1. general pressure range for conventional industrial applications: about 0.7MPa(7bar) typical use: drive
空气压缩机与冷干机启动顺序技术规范在压缩空气系统中，空气压缩机与冷干机的启动顺序需严格遵循设备运行逻辑，以确保系统稳定性及设备安全性。现就两类设备的启动顺序及操作规
The air oil content standard of the micro-oil screw compressor is measured under standard conditions and generally does not exceed 5ppm. However, in practical applications, the oil content may vary due to various factors. Some data show that the discharge of micro oil screw air compressor contains
The selection standard of oil-free air compressor is a decision-making process considering various factors. First of all, it is necessary to clarify the specific needs and purposes of using oil-free air compressors, such as the required amount of gas, working pressure, and the particularity of the working environment. These factors will directly
Q: Oil-free air compressor with water lubrication can really do oil-free? Answer: Water-lubricated oil-free air compressor can do oil-free. The water-lubricated oil-free air compressor adopts single-screw technology to replace oil with water to achieve lubrication, cooling, sealing, noise reduction and other effects, providing high quality
Yes, it is theoretically possible to turn on the air compressor first and then the freeze dryer, but it is not the best operation sequence. In actual operation, although the air compressor provides the compressed air required by the freeze dryer, in order to ensure the normal operation of the equipment and the quality of the compressed air, it is more recommended.
There is no fixed standard for the oil content of compressed air oil. It usually depends on the type, design, use environment and maintenance conditions of the compressor. The micro-oil air compressor is designed to control the oil content in the compressed air as much as possible.
There may be many reasons for the slow air intake of screw air compressors. The following are some common reasons and corresponding solutions: 1. common reasons The air filter is blocked. The air filter may accumulate a large amount of dust and impurities after long-term use. Hindering the normal entry of air
Q: Do air compressors in the food industry have to be oil-free? A: Yes, oil-free air compressors must be used. Food safety is now getting more and more attention, and no one wants to have lubricating oil residues in the food they eat. So the best option is to use oil-free
Condensed water in the air pipe of the air compressor is a common problem, which is mainly formed by the condensation of water vapor in the compressed air. If not handled in time, it may cause equipment corrosion, damage to pneumatic components, product quality degradation (such as paint bubbles) or pipeline blockage. The following is systematic
