In the application of silent oil-free air compressor, you must first understand what is silent oil-free air compressor? What are its advantages? What industries can it be applied to? In combination with their own environment, we should consider how to select specific models.

Selection of silent oil-free air compressor

1,、 What is silent oil-free air compressor?

The oil free cup sleeve piston is used for air compression. To put it bluntly, it is used to provide power for instruments and equipment requiring pressurization and for working conditions such as purging and cleaning.

2,、 What are the advantages of silent oil-free air compressor?

No need to add lubricating oil, the air is cleaner, and the output gas quality is higher.

New PLC control system, intelligent and digital control, with automatic start and stop protection, current and voltage

3. Overload protection, high temperature thermal protection and other functions are safe and reliable. More stable performance. Effectively improve the service life of the compressor.

4. Excellent noise control technology and high elastic shock absorption and noise reduction design, noise value ≤ 50db (A), suitable for all indoor environments.

5. The output gas pressure is stable without fluctuation and has high accuracy.

6. All copper coils, precision components and reasonable design make the product quality excellent.

Silent oil-free air compressor is widely used in all walks of life due to the above advantages.

Selection of silent oil-free air compressor

3,、 What industries can mute oil-free air compressors be used in?

1. Application field of laboratory equipment: The laboratory generally needs to use a silent oil-free air compressor to provide high-quality compressed air for the experiment. The laboratory often uses air supply equipment to assist the experiment. Once the compressed air is not pure enough, it is easy to react with chemical substances, leading to actual failure, and even serious accidents.

2. Medical industry: In the medical industry, people use air compressors to make medicine, provide oxygen for hospitals, and clean supply rooms.

3. General machinery field: compressed air is the second largest power energy after electricity, and it is also a process gas source with multiple uses. It also plays a very important role in heavy manufacturing industries such as electricity, petrochemical, metallurgy, machinery, automobile manufacturing, etc.

4. Food industry: In the food industry, air compressors are also needed in many places, such as bottle washing machines, blenders, food packaging, food processing, etc. in beverage factories.

5. Spraying industry: oil-free air compressor is used in the spraying industry to improve product quality and ensure its process and production safety. For example, compressed air delivers paint materials evenly in automobile spraying operation, providing safe and efficient driving force for spraying and polishing, atomizing paint materials, so as to achieve smooth, smooth and good decorative appearance.

6. Electronics industry: The requirements for making parts and components in the electronics industry are very precise, and every detail can not be lost. Compressed air is used in the electronics manufacturing industry, which is an environment-friendly and stable power source to achieve production automation. The command of the controller can be executed by controlling some pneumatic components.

7. Textile industry: In the textile industry, air jet looms need dry and oil-free compressed air, so the pure compressed air provided by oil-free compressors can ensure the quality of finished fabrics.

8. Air separation industry: As a major equipment, air compressors are indispensable in air separation units, and they are also "big energy consumers" of the units. During the operation of the air separation unit, once the air compressor has problems, it will seriously affect the normal operation of the air separation unit. The equipment uses include: nitrogen generator, oxygen generator, etc.

Selection of silent oil-free air compressor

4,、 What are the reference methods for selection of silent oil-free air compressor?

1. Selection of working pressure (exhaust pressure):

When the user is ready to purchase an air compressor, first determine the working pressure required at the air end, add 1-2 bar allowance, and then select the pressure of the air compressor (the allowance is to consider the pressure loss from the installation site of the air compressor to the actual gas end pipeline distance, and appropriately consider the pressure allowance between 1-2 bar according to the length of the distance). Of course, the size of the pipe diameter and the number of turning points are also factors that affect the pressure loss. The larger the pipe diameter and the fewer turning points, the smaller the pressure loss; On the contrary, the pressure loss is greater.

Therefore, when the distance between the air compressor and each gas end pipe is too far, the diameter of the main pipe should be appropriately enlarged. If the environmental conditions meet the installation requirements of the air compressor and the working conditions permit, it can be installed nearby at the gas end.

2. Selection of volume flow:

① When selecting the volume flow of the air compressor, first understand the volume flow of all air consuming equipment, and multiply the total flow by 1.2 (that is, increase the margin by 20%);

② The new project can be selected according to the flow value provided by the design institute;

③ Ask the gas equipment supplier about the volume flow parameters of the gas equipment for selection;

④ For the reconstruction of air compressor station, the original parameter value can be referred to and the actual gas consumption can be combined for selection;

Proper type selection is beneficial to users and air compressor equipment. Too much waste in type selection and too little type selection may cause the air compressor to be in the loading state for a long time, or the air consumption is insufficient or the pressure cannot be increased.

3. Relationship between power, working pressure and volume flow

Under the condition of constant power, when the speed changes, the volume flow and working pressure also change accordingly; For example, for a 22KW air compressor, the working pressure is determined to be 7bar during manufacturing, and the speed is calculated according to the technical curve of the compressor host, and the displacement is 3.8 m3/min; When the working pressure is determined to be 8bar, the speed must be reduced (otherwise the drive motor will be overloaded). At this time, the air displacement is 3.6 m3/min; Because the speed is reduced, the exhaust gas is reduced accordingly.

The above describes the knowledge of mute oil-free air compressor from four aspects: definition, advantages, application industry and model selection. If you still don't understand the details, you can communicate by private letter.
