The pressure values of air compressors vary depending on their type, design, and usage scenarios. The following is a detailed summary of the air compressor pressure values:
common pressure ranges:
in general, the use of air compressor pressure is 6-8 MPa (MPa).
According to the specific process needs, the commonly used pressure range can be extended to 4-12 MPa.
Classification by pressure level:
low pressure: working pressure of gas circuit ≤ 1.3MPa.
Medium pressure: gas circuit working pressure between 1.3 ~ 4.0MPa.
High pressure: the working pressure of the gas circuit is 4.0 ~ 40MPa and above.
Working pressure of air compressors of different power:
smaller air compressors (power less than 15kW) generally have a working pressure of 6-8bar (approximately equal to 0.6-0.8MPa, because 1bar & asymp;0.1MPa).
The working pressure of larger air compressors (power greater than 15kW) is generally 8-14bar (approximately equal to 0.8-1.4MPa).
Pressure requirements for special application areas:
the pressures commonly used in industry are 0.7 MPa and 0.8 MPa, but some applications require higher pressures.
Automobile tire pressure is generally between 0.2 MPa and 0.3 MPa.
Pressure Unit:
the pressure of the air compressor is generally in megapascals (MPa), and some areas use kilopascals (kPa), bar (bar) and other units.
In summary, the pressure value of the air compressor is different in different situations, but the common pressure range is between 4-12 MPa. In practical applications, it is necessary to select an appropriate air compressor and its pressure value according to specific process requirements and usage scenarios.
Water lubrication and dry oil-free methods have their own advantages and applicable scenarios, so it is impossible to generalize which is better. The following is a comparison between the two: Advantages of water lubrication: High purity Output: Water-lubricated air compressors use water as a lubricant, which can remove the compression process
The standards for medicinal compressed air are usually very strict to ensure that the air quality in the pharmaceutical production process meets relevant regulations and quality requirements. The following is a detailed summary of medicinal compressed air standards: 1. main standard indicators cleanliness compressed air
When the air compressor cannot be started again after the air compressor is stopped, it may be caused by various reasons. The following are some common reasons and corresponding solutions: Power problem: Check whether the power supply is normal, and confirm the air pressure
In the field of modern industry, efficient and environmentally friendly compression equipment has been paid more and more attention. The low-pressure oil-free and water-lubricated screw air compressor produced by Shanghai Granklin Group is an outstanding representative of this trend. The air compressor uses advanced water lubrication technology, Che
Screw air compressor does exist without oil pressure model, that is, oil-free screw air compressor. This type of air compressor does not need to use lubricating oil during operation, so it is also called oil-free air compressor. They operate primarily through water lubrication or other oil-free lubrication techniques, thus avoiding
In the air compressor system, the following components are usually regarded as pressure vessels: Air storage tank: Air storage tank is an important pressure vessel in the air compressor system, which is used to store compressed air. It bears the pressure of internal compressed air, so it must have sufficient strength and
The operating efficiency of an air compressor is a key indicator to measure its performance, usually expressed in terms of energy efficiency ratio or specific power. According to the "GB19153-2019 Volumetric Air Compressor Energy Efficiency Limits and Energy Efficiency Ratings" standard, combined with industry data, the operating efficiency range of air compressors is
Air compressor is a kind of important equipment widely used in various industrial production, but it is also a potentially dangerous equipment. Therefore, safe operation procedures and precautions must be observed when operating air compressor to ensure personal safety and equipment Normal operation. Lower
Definitions and classification of standard analytical 1. for all-oil-free air compressors 1. Definitions Full oil-free air compressor refers to the compression process does not use lubricating oil, and the compressed gas does not contain oil in the high cleanliness of the equipment. The core lies in the use of water lubrication, ceramic bearings or
The first maintenance (first maintenance) of the air compressor has many functions. It is of great significance to ensure the long-term stable operation of the air compressor, improve the performance of the equipment and extend the service life. The following are the main functions of the first maintenance of the air compressor: 1. Check and confirm the comprehensive inspection of the equipment status
