When using a silent oil-free air compressor, you must first understand what is a silent oil-free air compressor? What advantages does it have? What industries can it be applied in? Then consider how to choose a specific model in combination with your own environment.
1. What is a silent oil-free air compressor?
The oil-free leather cup sleeve piston method is used for air compression. To put it bluntly, it is to provide power for instruments and equipment that need to be pressurized and to be used for purging, cleaning and other working conditions.
2. What are the advantages of silent oil-free air compressors?
There is no need to add lubricating oil, the air is cleaner, and the output gas quality is higher.
New PLC control system, intelligent, digital control, with automatic start and stop protection, current, voltage
3. Overload protection, high temperature thermal protection and other functions, safe and reliable. The performance is more stable. 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 precision.
6. All copper coils, precision parts and reasonable design, the product quality is excellent.
Silent oil-free air compressors are widely used in various equipments in all walks of life because of the above advantages.
3. In which industries can the silent oil-free air compressor be applied?
1. Application fields of laboratory equipment: laboratories generally need to use silent oil-free air compressors to provide high-quality compressed air for experiments. Laboratories often use air supply equipment to assist experiments. Once the compressed air is not pure enough, it is easy to It reacts with chemical substances, leading to the failure of real danger, and in severe cases, it will cause safety accidents.
2. Medical industry field: In the medical industry, people use air compressors to make medicine, provide oxygen for hospitals, supply room cleaning, etc.
3. General machinery field: Compressed air is the second largest power source next to electricity, and it is also a process gas source with multiple uses. It also plays an important role in heavy manufacturing industries such as electric power, petrochemical industry, metallurgy, machinery, and automobile manufacturing. very important role.
4. Food industry: In the food industry, air compressors are also used in many places, such as bottle washing machines in beverage factories, mixers, food packaging, and food processing.
5. Spraying industry: Oil-free air compressors are used in the spraying industry to improve product quality and ensure process and production safety. For example: compressed air evenly transports paint materials in automobile spraying operations, provides safe and efficient driving force for spraying and polishing, and atomizes paint materials to achieve smoothness and good decorative appearance.
6. Electronics industry: The electronics industry has very fine requirements for making parts, and every detail cannot be missed. Compressed air is used in the electronics manufacturing industry, and it is an environmentally friendly and stable power source to realize production automation. It can be controlled by some Pneumatic components to carry out the commands of the controller.
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 cloth.
8. Air separation industry: As the main equipment, the air compressor is indispensable in the air separation plant, and it is the "big energy consumer" of the plant. In the process of air separation operation, once there is a problem with the air compressor, it will seriously affect the normal operation of the air separation plant. The equipment uses are: nitrogen generator, oxygen generator, etc.
4. What are the reference methods for silent oil-free air compressor selection?
1. Selection of working pressure (exhaust pressure):
When users are going to purchase an air compressor, they must first determine the working pressure required by the gas end, add a margin of 1-2 bar, and then select the pressure of the air compressor, (the margin is considered from the air compressor The pressure loss of the distance from the installation site to the actual gas end pipeline, according to the length of the distance, the pressure margin should be properly considered between 1-2 bar). Of course, the size of the pipeline diameter and the number of turning points are also factors that affect the pressure loss. The larger the pipeline diameter and the fewer the turning points, the smaller the pressure loss; otherwise, the greater the pressure loss.
Therefore, when the distance between the air compressor and each gas end pipeline is too far, the diameter of the main pipeline 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 near the gas end.
2. Selection of volume flow:
① When selecting the volume flow rate of the air compressor, you should first understand the volume flow rate of all gas-consuming equipment, and multiply the total flow rate by 1.2 (that is, enlarge the margin by 20%);
② New projects can be selected according to the flow value provided by the design institute;
③ Learn about the volume flow parameters of the gas equipment suppliers from the gas equipment supplier for model selection;
④ Air compressor station reconstruction can refer to the original parameter value combined with the actual gas consumption for selection;
Appropriate selection is beneficial to both the user and the air compressor equipment. Too large selection is wasteful, and too small selection may cause the air compressor to be in a loaded state for a long time, or the air consumption is insufficient or the pressure cannot be pumped up.
3. The relationship between power, working pressure and volume flow
In the case of constant power, when the speed changes, the volumetric flow rate and working pressure will also change accordingly; for example: for a 22KW air compressor, the working pressure is determined to be 7bar at the time of manufacture, calculated according to the technical curve of the compressor host Rotating speed, displacement is 3.8 m3/min; when the working pressure is determined to be 8bar, the rotating speed must be reduced (otherwise the drive motor will be overloaded), at this time, the displacement is 3.6 m3/min; because the rotating speed is reduced, the exhaust The gas is also reduced accordingly.
