The main differences between oil-free air compressors and ordinary air compressors are reflected in the working principle, gas cleanliness and application scenarios, as follows:
1. Lubrication and cooling method
ordinary air compressors usually rely on lubricating oil to achieve sealing, lubrication and cooling during compression, and the oil system is its core component. The oil-free air compressor (such as granklin water lubricated screw air compressor) adopts innovative design, replaces lubricating oil with water, and completes compression through the coordinated movement of single screw and star wheel, thus avoiding oil participation from the source and completely eliminating the risk of oil pollution.
2. Cleanliness of output gas
ordinary air compressor due to the use of lubricating oil, compressed air may be residual trace oil, through additional filtering equipment to achieve clean standards. The air output by the oil-free air compressor is natural and oil-free, which can directly meet the needs of medical, pharmaceutical, food and other industries that require extremely high gas cleanliness, without subsequent degreasing treatment, simplifying the process.
3. Applicable Scenario Differences
ordinary air compressors are suitable for general scenarios that do not require high gas cleanliness, such as ordinary industrial power drives. Oil-free air compressors are designed for areas with zero tolerance for pollution, such:
4. Maintenance and operating costs
ordinary air compressor needs regular maintenance of the oil system, replacement of lubricating oil and filter, long-term use of high cost. Oil-free air compressor due to the oil-free design, reducing the wearing parts and maintenance links, more stable operation, lower long-term cost.
Granklin water-lubricated screw air compressor provides an efficient and clean gas solution for enterprises through the oil-free compression technology of single screw plus star wheel, which is the ideal choice for the pursuit of high-quality production environment.
Answer: Oil-free air compressor compresses air that does not contain oil, and oil-free compressed air is used in industrial production. In industries with high air requirements, such as textiles, metallurgy, food
When the factory chooses the air compressor for the air pressure nitrogen generator, the selection of frequency conversion and power frequency should be combined with the comprehensive evaluation of gas characteristics and operation requirements. The core difference between the two lies in the air supply adjustment mode: the variable frequency air compressor can dynamically adjust the speed according to the actual air consumption to realize on-demand air supply;
Whether the air compressor needs to be customized depends on the specific use scenario and needs. Generally speaking, the standard air compressor on the market can meet most of the common needs. These standard air compressors are usually mass-produced, cost-effective, and more maintenance and accessories.
The service life of the air compressor oil and gas barrel is affected by many factors, including the material quality, working pressure, working temperature and volume of the oil and gas barrel. Generally speaking, the service life of the air compressor oil and gas barrel is about 2 to 3 years. However, it is also possible to have a useful life of up
In general, air compressors are designed to maintain a specific pressure range to ensure that they can meet the needs of various application scenarios. Generally speaking, the pressure of the conventional air compressor is maintained at a certain level, which is
The energy efficiency of scroll compressors and screw compressors is not exactly the same. Each of them has different characteristics and application scenarios, so there are differences in energy efficiency. Scroll compressors usually have high adiabatic efficiency, which means that when compressing gas
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.
Q: oil-free air compressor and oil air compressor which is good? A: oil-free air compressor. If conditions permit, the first choice is of course the oil-free air compressor, which has higher quality of compressed gas. The "water-lubricated air compressor" produced by Shanghai Granklin air compressor
Air compressors are widely used in factories, covering almost all aspects of factory production and operation. The following is a detailed summary of the main application areas of air compressors in the factory: 1. Power supply pneumatic tools and equipment: air compressors are pneumatic drills and pneumatic screwdrivers
The core technical measures of the air compressor to ensure that there is no water. The compressed air will carry a large amount of water vapor during the compression process due to the increase in temperature, and it is easy to condense into liquid water after cooling. In order to ensure the output of dry gas, it is necessary to control the moisture through the following steps: 1. Condensate primary treatment cooling
