For 15 processing centers, it is recommended to allocate air compressors with a displacement of 6 to 8 cubic meters per minute and a power of 37 to 55 kW, depending on your processing method.
First, let's talk about how it was calculated. The gas consumption of a single processing center is generally between 0.3 and 0.5 cubic meters per minute, depending on what it mainly uses. If you only change the knife, clamping these basic actions, a single about 0.3 cubic meters per minute is enough. If compressed air is used to blow iron filings and cool the cutting point during processing, the single unit may reach 0.5 or even higher.
15 units are calculated at 0.4 cubic meters per minute, and the theoretical total demand is 6 cubic meters per minute. However, it is not 15 units that use gas at full capacity at the same time, so it is necessary to take a simultaneous use coefficient, which is generally 0.7 to 0.8, which is 4.2 to 4.8 cubic meters per minute. Add in about 15% to 20 leaks in the pipeline, and that's 5 to 5.8 cubic meters per minute. Finally, a margin of 10 to 20 percent should be left to cope with the peak and future expansion of production. The final demand is about 6 to 7 cubic meters per minute.
Therefore, the air compressor displacement of 6 to 8 cubic meters per minute is relatively safe. The corresponding power is in the range of about 37 to 55 kW. In terms of working pressure, the processing center generally needs to 0.6 to 0.7 MPa, plus pipeline loss and allowance, it is enough to choose a model with a rated exhaust pressure of 0.7 MPa, and do not choose a higher pressure. For every additional 0.1 MPa, the energy consumption increases by about 7%, wasting electricity.
It is recommended to match 3 to 5 cubic meters of air storage tank to buffer pressure fluctuation and avoid pressure drop when multiple air tanks are used at the same time.
If there is a large number of air blowing and cooling processes in your processing, the air consumption will be obviously too large. It is suggested to directly match the air volume according to 8 cubic meters per minute or even higher. It is better to match the air pressure instead of being too small, so as not to report to the police and stop the machine when working, which will affect the production.
Centrifugal air compressors are widely used in many industries. The following are its main application areas: Manufacturing: Automobile Manufacturing: Used to supply pneumatic tools and painting equipment on the automobile manufacturing line. Electronics Manufacturing: Manufacturing equipment for semiconductors and other precision
The role of oil-free air compressors is mainly reflected in the following aspects: 1. to provide pure oil-free compressed air The biggest advantage of oil-free air compressors is that they can provide 100 percent oil-free pure compressed air. The traditional oil air compressor is required in the compression process.
For screw air compressor can also be divided into oil air compressor and oil free air compressor. For the industry in the pharmaceutical, medical and other high quality requirements of compressed air, oil-free requirements of these industries to choose oil-free air compressor is not questioned. But...
In the operation of semiconductor equipment, nitrogen air compressor plays a vital role. As an inert gas, nitrogen is mainly used to provide an oxygen-free environment in semiconductor manufacturing to prevent the material from forming with oxygen or other harmful gases during processing.
Analysis of Oil Content in Atmospheric Environment and Compressed Air Oil content in atmospheric environment is usually at a very low level, and the specific value is affected by geographical location, environmental conditions and other factors. In a clean outdoor environment, the amount of oil in the air (mainly from motor vehicle exhaust, industrial
According to international standards and industry norms, the oil content of compressed air in contact with food shall be strictly controlled by grading. The specific standards are as follows: 1. direct contact with food scenes (such as ingredients, fermentation and stirring) International standard: ISO 8573-1:2010 Class 1: Oil content ≤ 0.0
Air compressor export oil content standards are usually formulated by the International Organization for Standardization (ISO) or related industry associations. For example, ISO 8573-1 is an important standard for oil content testing of air compressors, which specifies three levels of oil content: oil content ≤ 0.01 mg/m &
Medical air compressor plays a variety of important roles in the medical field. The following is a detailed summary of its role: 1. provide air source for medical and health care equipment. Medical air compressor mainly provides sufficient and clean air source for medical equipment that needs air source. These
Answer: Frequency conversion direct screw air compressor has the following advantages: 1, energy saving effect is remarkable: through the intelligent control system, according to the actual demand automatically adjust the working speed, so as to effectively reduce energy consumption, save running
The replacement cycle of air compressor oil mainly depends on the type and quality of the oil, as well as the working environment and running time. Generally speaking, the replacement cycle of air compressor oil can be divided into the following situations: 1. classified according to the type of oil mineral oil: due to its low viscosity, the capacity
