1. How to choose the right model?
It is suggested to purchase compressors according to the actual gas consumption requirements. When purchasing power frequency air compressors, it is suggested that 1.1-1.2 times of the peak gas consumption value is the most appropriate. If the model is too large, the unloading (idling) time will be too long and electricity charges will be wasted. If conditions permit, please give priority to permanent magnet frequency conversion air compressors. The air supply range of frequency conversion air compressors is 10-100, and constant pressure air supply will not waste electricity charges due to unloading (idling), when purchasing a permanent magnet variable frequency air compressor, it is generally recommended that more than 1.3 times the peak value of gas consumption is the most appropriate.
The performance of the air compressor is still stable.
The key component of the air compressor is the screw head. For the air compressor, the head is just like the CPU of a mobile phone and a computer, which is directly related to the service life of the air compressor. At present, the better heads on the market include Atlas Copco and gran klin, followed by Shouli, Ingersoll Rand, Hanzhong AA/AB heads, and Hanzhong AC or Tongrun heads. The most common head is Bowes, which is not necessarily bad. But as long as the brand head quality is generally not bad. If the company stops production due to poor air compressor quality, the loss must be much higher than the cost of ordering an air compressor.
3. Energy efficiency & specific power
when purchasing an air compressor, don't just look at the surface price. As an industrial product, the air compressor is still very particular about the price and the goods. The priority should be the specific power of the machine. The purchase cost of the air compressor often only accounts for 5% of the total service life of 10 years, the rest of the maintenance cost accounts for 5%, and the maximum consumption cost is about 90% of the electricity cost. Therefore, it is important to buy an inappropriate air compressor, the loss is not just the tens of thousands of dollars when buying air compressors, and the huge electricity bills generated by low energy efficiency. It will certainly greatly increase the cost of production and operation.
4. Imported machine
at present, 98% of the products in the domestic air compressor market are assembled in China. Oil-injected screw machines must not blindly follow such oral agreements as believing that overseas production is pure import. Unless it is an oil-free model, if you have to buy pure import, please be sure to provide the customs declaration certificate of the corresponding production batch of the equipment.
With the rapid development of Internet technology, it is becoming more and more convenient to purchase oil-free screw air compressors. Just search the Internet "air compressor" a lot of information related to it will be displayed in front of everyone, so how to in this a lot of letters
Water-lubricated air compressor, since it is the use of water as a lubricant will certainly be rich in water vapor, then we need post-processing equipment to deal with the gas discharged from the water-lubricated air compressor. Refrigerated dryers, adsorption dryers and other dryer equipment, as well as filters, gas tanks, etc. can effectively eliminate water molecules in water vapor.
View detailsThe main function of compressor lubricating oil is to lubricate and seal the male and female rotors and bearings. In addition to lubricating, cooling and sealing the mechanical parts, it also plays a role in cooling the compressed gas. But in the actual production work, if the lubricating oil coking will seriously affect
The trend of the air compressor market is also filtered to the permanent magnet frequency conversion and two-stage compression. Permanent magnet frequency conversion, the biggest feature is energy saving. As long as the user's gas consumption and gas consumption status is not always in a full load state, permanent magnet frequency conversion products can achieve the actual energy saving effect.
China-made oil-free air compressor manufacturers, Shanghai Granklin Group, water-lubricated air compressor head is fully localized, compressed gas is 100% oil-free. Suitable for high-end industries, can match the pharmaceutical, chemical, food and other high-end manufacturing and processing industries in China. For food, medicine, textile, chemical and other industries with high gas requirements, oil-free air compressors are gradually recognized by enterprises and are widely used by more and more companies,
View detailsWhen the air compressor needs oil-free air, it is usually selected from the micro-oil air compressor, dry air compressor and water lubricated air compressor. The temperature of the micro-oil is low, the gap between the yin and yang rotors is small, and the loss of gas is small. The dry-type oil-free yin-yang rotor has a large gap and large gas consumption. Because there is no oil, the airtight effect is not good. One of the functions of the oil in the micro-oil air compressor is the oil film, which plays a sealing role. Efficiency is better.
View detailsIntake valve loading principle steps: 1, start, the motor is turned on, the host starts to run, the intake valve hole suction, the check valve is opened, the compressed oil and gas enter the oil and gas tank, and the lubricating oil in the oil and gas tank is sprayed into the host head (After the temperature control valve). The pressure rises and part of the pressure passes
The textile industry's requirements for compressed air are not only the oil content in the air, but also water and impurities. However, in these three items, the oil is more difficult to completely filter, so the quality of the gas used can be said to determine the grade of a textile enterprise. So how do you want to buy oil-free air compressors in the textile industry?
View detailsOil-free air compressors can be divided into two categories from the perspective of lubrication: self-lubricating oil-free air compressors and water-lubricated oil-free air compressors. These two air compressors have both advantages and disadvantages, and there is no conclusion as to who is good or bad. Oil-free water lubrication air compressors are generally screw air compressors, the main
The oil-free air compressor of the domestic brand has been officially produced in China for many years, and the products are also improving year by year. Companies that can do it in the industrial application scenario are also enriching cases. "Shanghai granklin group" water lubricated air compressor factory is one of the oil-free air compressor production factories. the production base is in Baoshan district of Shanghai. if you have any questions about the domestic oil-free air compressor, you can visit our factory at any time.
