There are some obvious differences between micro-oil screw air compressor and oil-free screw air compressor in design and operation principle. Here are the main differences between the two:
lubrication method:
micro-oil screw air compressor: This type of air compressor uses a small amount of lubricating oil to lubricate the screw and bearings. Lubricating oil not only helps reduce wear, but also improves compression efficiency. However, this also means that the compressed air may contain traces of oil.
Oil-free screw air compressor: As the name suggests, this type of air compressor can work normally without additional lubricating oil during operation. They usually use special designs and materials to reduce the friction between the screw and the bearing. Therefore, the compressed air produced by the oil-free screw air compressor is almost completely oil-free.
Compressed air purity:
micro-oil screw air compressor: Due to the use of lubricating oil, the compressed air may contain trace amounts of oil, which may affect the air quality. In some applications that do not require high air quality, micro-oil screw air compressor is a feasible choice.
Oil-free screw air compressor: Because it does not rely on additional lubricating oil, the compressed air produced is relatively pure, which is suitable for applications with very high air quality requirements, such as medical, food and pharmaceutical industries.
Maintenance and use costs:
micro-oil screw air compressor: Due to the use of lubricating oil, the lubricating oil and oil filter need to be replaced regularly, which may increase maintenance costs. In addition, if the lubricating oil leaks or is not handled properly, it may cause pollution to the environment.
Oil-free screw air compressor: Although there is no need to add additional lubricating oil, in order to maintain its normal operation and extend its service life, it is still necessary to replace the lubricating oil regularly. Its design and manufacturing process is more complex, so the initial investment is usually higher.
Application areas:
micro-oil screw air compressor: It is suitable for some application scenarios that do not require high air quality or can accept trace oil, such as industrial manufacturing, automobile maintenance, etc.
Oil-free screw air compressor: It is more suitable for application scenarios with strict requirements on air quality, such as precision manufacturing, food processing, medical equipment, etc. In these areas, any oil fraction may have a negative impact on product quality or equipment performance.
In summary, there are significant differences between micro-oil screw air compressors and oil-free screw air compressors in terms of lubrication methods, compressed air purity, maintenance costs and use costs, and application areas. The choice of compressor type depends on the specific application requirements and budget considerations.
As a special type of air compressor, the core advantage of oil-free air compressor is that it does not require lubricating oil during its operation, which greatly reduces the risk of oil pollution and improves the purity of the air. However, even oil-free air compressor, in the use of the process still need to pay attention to its
Medical air compressor is a special equipment for the hospital to produce clean compressed air, and water lubricated air compressor because of water instead of oil, so that the production of air is more pure, especially suitable for use in hospitals such a place with high air quality requirements, silently guarding the safety of patients.
The oil content standard of industrial compressed air varies according to the industry and application scenarios. The national standard for ordinary air compressors stipulates that the liquid oil content shall not exceed 5 mg/m & sup3;, the oil vapor content shall not exceed 0.5 mg/m & sup3;; However, industries with high requirements such as medicine, food and electronics usually need
Air compressor maintenance cycle due to different manufacturers, models and conditions of use vary. For the water-lubricated oil-free variable frequency screw air compressor of Shanghai Granklin Group, the maintenance period is usually recommended to be determined according to the following factors: manufacturer's recommendations
The main reasons that affect the electricity bill of the air compressor are as follows: The rated power of the air compressor: The rated power of the air compressor is one of the important factors that affect the electricity bill. The greater the rated power, the higher the power consumption per unit time, resulting in an increase in electricity charges. Because
The air consumption of the punch is to calculate the volume of each air cylinder, multiply it by the number of actions per minute, add it all together, and add a margin of 20% to 30 to obtain the required air compressor size. The water lubricated air compressor because the output of the air does not contain oil, can keep the air system of the punch clean, reduce the failure, is a very good choice for the punch air supply.
The automatic drainage device of the air compressor is an important part of the air compressor system. Its main function is to automatically discharge the condensed water in the pipeline, the gas storage tank, the oil-water separator and the filter. The following is a detailed description of the air compressor automatic drainage device:
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.
The pressure of the air compressor usually varies according to its type, specification and usage scenario. The following are some common pressure ranges of air compressors: 1. low-pressure air compressors are classified according to pressure levels: the working pressure is usually 0.7 to 1.2 MPa (trillion
Q: Oil-free air compressor is really oil-free? Answer: Water-lubricated air compressor is really oil-free. Use pure water to lubricate the compressed air to prevent oil from mixing into the compressed air, thereby avoiding pollution to the post-processing equipment. Using Shanghai Granklin Group
