The main basis for the national oil-free standard for compressed air is ISO 8573-1. According to this standard, the highest grade of oil-free compressed air, Class 0, requires an oil content of less than 0.01 mg/m & sup3;. This is the main indicator to measure whether compressed air is oil-free.
At the same time, different application areas may have different requirements. For example, in the Chinese Pharmacopoeia and GMP, the oil content of compressed air is required to be less than or equal to 0.1 mg/m & sup3;. The oil content of medical compressed air must be ≤ 0.1 mg/m & sup3;, which is also a more specific application standard.
In addition, there are other relevant standards and regulations, such as diving breathing compressed air in the United States and China requires oil content <5mg/m3, the United Kingdom is <1mg/m3 and so on. These standards are based on specific application needs and conditions.
Please note that the above information is for reference only, and the specific standards may vary according to different countries, regions and application areas. In practical application, the relevant standards and regulations should be consulted according to the specific situation.
To determine the required air compressor flow, need to combine the following key factors analysis: 1. core calculation formula According to the derivation of the ideal gas state equation, the required air compressor flow rate calculation formula is: Q = tV×(P2 & minus;P1 )× 1.1 where: q: air compressor
In the compressed air system of the semiconductor factory, there is a close relationship between the cold dryer (ie, the freeze dryer) and the air compressor. The main function of the cold dryer is to reduce the temperature of the compressed air, so that the water vapor in it is condensed and discharged, thereby providing dry compression
In the automobile manufacturing industry, the difference between oil-containing and oil-free compressed air is significant, mainly reflected in the product quality, equipment life, process stability and maintenance costs of four aspects, the specific analysis is as follows: 1. product quality differences oil-containing compressed air hazards electronic components.
The plan of two parallel operation of air compressors aims to realize stable gas supply, load balancing and energy-saving operation through the cooperative work of two air compressors. Its core points are as follows: 1. the core goal of parallel operation, stable gas supply: through the operation of two air compressors with one for use and one for standby or alternately, avoid
There are many hidden dangers in the air compressor, which are not only related to the safety performance of the equipment itself, but also related to the safety and health of the operators. The following are some of the main safety hazards: 1. the safety hazards of the equipment itself Explosion risk: Lubricating oil mixing: Atomized
The maintenance of screw air compressor should follow the "three-level maintenance system" (daily, monthly and annual), and make a plan in combination with the use time, environmental parameters and sensor data. The following are detailed requirements: 1. daily maintenance (daily/per shift) oil level inspection
Whether the air compressor can run continuously for 20 hours a day depends on a number of factors, including the type of air compressor, the working environment, the load situation and maintenance. The following is a detailed analysis of this problem: Air compressor type: Different types of air compressors have
The replacement cycle of the air filter (air filter) of the screw air compressor depends on the use environment and working conditions of the equipment. The following are some general suggestions on the replacement cycle of the air filter of the screw air compressor: the running-in period of the new machine: the newly purchased screw air compressor is running for about 500
If the screw air compressor does not open and run for a long time, it may produce a series of adverse consequences, including the following: internal dust and pollution: dust, oil and other impurities may accumulate inside the screw air compressor for a long time. These pollutants will not only
