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.
Granklin water lubricated air compressor has a reasonable structure and an ideal force balance: both sides of the screw of the oil-free air compressor are equipped with a star wheel symmetrical structure, so that the oil-free air compressor not only has no unbalanced inertial force, but also The axial force and radial force on the screw cancel each other out, making it have an ideal force balance.
Energy conservation and environmental protection is always advocated by our country, and the R & D teams of manufacturing enterprises are also trying to develop energy-saving equipment. The screw air compressor, as one of the important gas equipment for production enterprises, will inevitably cause environmental pollution in the process of use.
Oil-free and water-lubricated screw air compressor is a common model in the oil-free machine family. It uses pure water for lubrication, so the compressed air has high oil-free and water-free purity. Oil-free water lubrication screw air compressor in recent years in the market sales are very hot, price
Many friends want to buy "good" gas tank, good gas tank should be how to distinguish? Here are a few comments for a few points, for your reference:
Shanghai granklin two-stage compression air compressor, our two-stage compression air compressor adopts water-lubricated air compressor head, while saving energy and electricity, we make the whole machine oil-free, gas oil-free, make the gas pure and oil-free, can be applied to medical breathing grade compressed gas. The permanent magnet frequency conversion two-stage compression is superior to the ordinary power frequency single-stage in energy saving efficiency.
The replacement cycle of air compressor oil is divided into three situations: 1. Mineral oil is replaced every 3 to 4 months; 2. Semi-synthetic oil is replaced every 6 to 8 months; 3. Fully synthetic oil is replaced every 10 to 11 months. The air compressor shall have the following conditions
The food industry should use environmentally friendly oil-free screw air compressors. The main engine of the domestic oil-free screw air compressor is manufactured by itself. Shanghai granklin is currently a high-quality choice for food, pharmaceutical factories and tap water. It also
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.
The replacement cycle of air compressor oil is divided into three situations: 1. Mineral oil is replaced every 3 to 4 months; 2. Semi-synthetic oil is replaced every 6 to 8 months; 3. Fully synthetic oil is replaced every 10 to 11 months. The air compressor has the following conditions
Air compressor safety management measures 1, air compressor must have a pressure gauge and safety valve. The pressure gauge must be calibrated regularly. The safety valve and pressure regulator must act reliably, and the operating pressure of the safety valve shall not exceed 1.1 times of the rated pressure. Use of oil
