With the wide application of screw air compressor and the increasing demand of the market, oil-free screw air compressor has become more and more popular in the market in recent years. There are also many customers who will ask questions about oil-free screw air compressors. Today, the editor will briefly talk to everyone about the oil-free screw air compressor can be roughly divided into several categories: water lubrication type, dry grinding type, and reciprocating type.
1. water lubricated
since the oil-free air compressor uses stainless steel and ceramic composite rotors, its dynamic bearing system is completely oil-free. And because the water spray can reduce the speed of the equipment, the volumetric efficiency of water lubrication oil-free air pressure is higher.
2. dry grinding type
when the dry grinding oil-free air compressor is in operation, its screw rotor generates gas compression through high-speed expansion, and the screw of the dry grinding oil-free air compressor is sprayed with resin objects to protect the screw from high-speed friction. Damage.
3. reciprocating
miniature reciprocating oil-free air compressor motor single-axis drive, symmetrical distribution crank rocker mechanical structure. The arrangement of the single-shaft double-cylinder structure of the reciprocating oil-free air compressor can make the air flow of the equipment double the speed of the single-cylinder in the rated range, so as to solve the vibration and noise generated by the single-cylinder compressor well.
Of course, different industries have different requirements for oil-free air compressors, and users can choose according to their own production conditions.
Can't find a good brand for purchasing air compressor, and the air compressor sold nearby is not satisfied? The demand is real. The problem that you can't find a good business if you want to purchase a screw air compressor suitable for your own use appears in many factory projects. Contact me.
Whether the air compressor needs cooling water depends mainly on its cooling method. There are two main cooling methods for air compressors: air cooling and water cooling. Air-cooled air compressor: This compressor does not require cooling water. They dissipate heat through built-in fans and radiators,

The calculation of the air consumption at the end of the air compressor is a process involving multiple factors, which usually needs to be determined according to actual needs and usage scenarios. The following are some commonly used calculation methods and considerations: 1. basic formula Air compressor end gas consumption can be through the following public
As an important industrial equipment, air compressor has a wide range of docking industries, covering almost all fields that require power sources or compressed air. The following are some of the main industries of air compressor docking: mechanical processing industry and manufacturing: air compressor in mechanical processing
The air compressor itself is not directly regarded as special equipment. However, when the parameters of pressure vessels such as gas storage tanks exceed a certain range, these vessels will be regarded as special equipment. In China, according to the Special Equipment Safety Law and related regulations, special
Belt screw air compressor is a common type of air compressor. It uses a belt to connect a motor and a compressor to compress gas through the rotation of the screw. This air compressor has its unique advantages and disadvantages, the following is a comprehensive evaluation of the belt screw air compressor:
The price of the 20 cubic air compressor varies depending on the brand, model, function and purchase time. According to publicly released information, the price range of 20 cubic air compressors is relatively large, ranging from several thousand yuan to several hundred thousand yuan. in economy and middle-end cities
The pressure of the plant's gas source is lower at night than during the day, which may be caused by various reasons such as environmental temperature change, equipment operation status, pipeline system problems, user demand change or external factors interference. The following is a specific analysis: 1. the influence of environmental temperature change The temperature difference between day and night
