Q: What should I do if there is water in the gas of the air compressor?
Answer: Oil free air compressors are usually lubricated with water, and the compressed gas contains abundant water vapor. A better way is to remove water vapor from compressed gas through a post-treatment cold dryer or suction dryer, which can be effectively removed through a precision filter.
Q: What are the vulnerable and consumable parts of oil-free air compressors?
Answer: Oil free air compressors usually use screw compressors of the water lubricated series, and the consumables for water lubricated air compressors are air and water filter elements.
The wear and tear parts of water lubricated oil-free air compressors are relatively few, and maintenance of the compressor head is only necessary after running for a sufficient period of time. Regular maintenance only involves the air filter element and water filter element.
Q: Can the pharmaceutical industry use micro oil air compressors?
Answer: No way.
Micro oil air compressor is a special type of air compressor that uses a small amount of lubricating oil and has the characteristics of no leakage, no friction, and no pollution. However, this type of air compressor is not suitable for industries such as pharmaceuticals, food, and chemicals. Because the compressed air still contains a small amount of lubricating oil, the pharmaceutical industry needs to use oil-free air compressors.
The water lubricated oil-free air compressor produced by Shanghai Granklin Group is oil-free and widely used in pharmaceutical, electronic, chemical, semiconductor, food and other enterprises.
Q: Do air compressors in the food industry have to be oil-free?
Answer: Yes, an oil-free air compressor must be used.
Food safety is increasingly valued nowadays, and no one wants lubricating oil residue in the food they eat. So the best choice is to use oil-free air compressors. Currently, the water lubricated oil-free air compressors produced by Shanghai Granklin Group are widely used in industries such as food and healthcare, compressing oil-free air into production lines.
Wrong answer: Air compressors in the food industry do not necessarily need to be oil-free. Although the food industry has high requirements for air compressors, it is not necessary to use oil-free air compressors. The combination of an oil compressor and oil removal equipment can also meet the requirements, and it is more cost-effective, energy-saving, and can ensure that the compressed air is cleaner.
Summary: Oil-free air compressors are the ultimate choice in the food industry, and the importance of food safety is highly valued by both the government and individuals, making oil-free food.
Q: Is there a difference between oil-free air compressors and regular air compressors?
Answer: There are differences.
The oil content of the compressed gas from an oil-free air compressor is non oil. For example, the water lubricated oil-free air compressor produced by Shanghai Granklin Group uses water as the lubricant at the head of the air compressor, without the involvement of lubricating oil during operation.
Ordinary air compressors require lubricating oil at the head of the compressor, so the oil content of the compressed gas is relatively high. It cannot be applied in fields such as medicine, chemicals, and food.
Q: How do air compressors distinguish between frequency conversion and power frequency?
Answer: The air compressor manufacturer will indicate on the nameplate of the air compressor whether it is a power frequency air compressor or a variable frequency air compressor.
If the air compressor manufacturer does not indicate it on the nameplate, you can refer to the motor nameplate and controller label. On the working panel of the air compressor, you can also check if there is a prompt for variable frequency or power frequency.
Q: What is the difference between variable frequency air compressors and power frequency air compressors?
Answer: Compared to power frequency air compressors, variable frequency air compressors have more stable air pressure and smoother current.
The most energy-efficient variable frequency air compressor is a permanent magnet variable frequency air compressor using a permanent magnet motor, which significantly reduces energy consumption.
When the power frequency air compressor starts, the impact on the power grid is greater than that of the variable frequency air compressor.
The frequency conversion air compressor also significantly reduces noise, and it is recommended to choose a permanent magnet frequency conversion air compressor when purchasing air compressors.
Question: 1m ³ How much mpa does the air compressor produce?
Answer: The pressure of the air compressor is customized according to user needs, and the amount of exhaust does not determine the pressure.
Q: How to determine the quality of an oil-free air compressor?
Answer: The quality of an oil-free air compressor depends on the cleanliness of the compressed gas and whether the oil content in the air meets the standard. This is the most basic, and then look at the overall appearance and working sound of the oil-free air compressor to see if there are any scratches or abnormal noise.
The quality of compressed gas is the most important factor in determining whether the spare parts of the entire air compressor are qualified or not, and the quality of a non oil free air compressor. No matter how well the compressed gas does not meet the standard, it is useless to promote it.
Q: Is 100% oil-free compressed air present?
Answer: 100% oil-free compressed air means that the oil content in the compressed gas must be lower than a certain value.
Because there is also oil and gas in the atmosphere, the gas that comes out after passing through an oil-free air compressor, air storage tank, cold dryer, and precision filter can meet the usage standards.
The water lubricated oil-free air compressor produced by Shanghai Granklin Group can be referred to as oil-free air after being treated in the above way.
