Common air compressor mainly has the following three kinds:
piston air compressor: This is a relatively early type of air compressor, its structure is simple, the price is relatively low, so in some of the air compressor performance requirements are not high occasions still have applications. However, due to its relatively slow speed, more wearing parts and frequent maintenance, it has been gradually replaced by other types of air compressors.
Screw air compressor: Screw air compressor is one of the most used air compressor types on the market. Its operating principle is that a pair of parallel-arranged male and female rotors (ie screws) rotate in the cylinder, so that the air between the rotor cogging continuously produces periodic volume changes, and the air is transported from the suction side to the rotor axis. The output side realizes the whole process of suction, compression and exhaust of the screw air compressor. Screw air compressor has the advantages of simple structure, high reliability, high efficiency and low noise.
Centrifugal air compressor: Centrifugal air compressor is a kind of turbo compressor. Its working principle is that the impeller drives the gas to rotate at a high speed, so that the gas generates centrifugal force. Due to the expansion flow of the gas in the impeller, the gas The flow rate and pressure after passing through the impeller are increased, and compressed air is continuously produced. Centrifugal air compressors are generally used in occasions that require large flow, and have the advantages of compact structure, light weight, small footprint, large displacement, and convenient maintenance.
In addition to the above three, there are some other types of air compressors, such as sliding vane air compressors, scroll air compressors, etc., but these types of air compressors are relatively less used. When choosing an air compressor, you need to choose the most suitable type according to the specific usage scenario and needs.
When the flow rate (exhaust volume) and pressure (exhaust pressure) of the air compressor are known, the power can be calculated by the following formula: power (kW)= 367 exhaust pressure (bar)× exhaust flow rate (m & sup3;/min) or the specific power formula (input power needs to be known
Definitions and classification of standard analytical 1. for all-oil-free air compressors 1. Definitions Full oil-free air compressor refers to the compression process does not use lubricating oil, and the compressed gas does not contain oil in the high cleanliness of the equipment. The core lies in the use of water lubrication, ceramic bearings or
Q: What is the difference between oil-injected screw and oil-free screw air compressor? A: Oil-injected screw air compressor, as the name suggests, when the air compressor head is working, the inside of the head is lubricated and cooled by lubricating oil. Therefore, the oil content in the compressed gas is relatively large, and the latter
Answer: The maintenance of the screw air compressor can be used for more than 10 years, the life of the air compressor depends on the use of the environment, maintenance and so on. "Water-lubricated oil-free snail produced by Shanghai Granklin (Group)
The exhaust pressure of most air compressors is set to 8kg (0.8MPa or 8bar), mainly because this pressure value has reached a comprehensive balance in terms of applicability, equipment compatibility, energy consumption and safety, and is the "golden pressure" in industrial applications.
Answer: The air tank is a drain valve, the amount of water vapor or more can use the dryer (freeze dryer, adsorption dryer), in the collocation of post-processing with precision filters, you can effectively remove the water in the compressed air.
Screw air compressor can work continuously without stopping, especially some specific models, such as water-lubricated oil-free screw air compressor, can run for a long time. When the pressure reaches the set value, the air compressor can automatically stop, and the permanent magnet variable frequency air compressor will run at low speed. In addition, the snail
Professional Description of Working Pressure Setting of Air Compressor The setting of working pressure of air compressor requires comprehensive evaluation of equipment performance, gas demand and operating cost. There is no absolute advantage or disadvantage, but the principle of "on-demand adaptation" should be followed. The following from the technical characteristics, economic
Fully oil-free and oil-free lubrication differ mainly in concept and field of application. Conceptually: completely oil-free means that in machinery or equipment, the original intention is to use no lubricating oil or grease at all. However, in actual operation, the surface of the part may be shaped.
Whether the air compressor is equipped with backup equipment depends on the specific application scenario and needs. The following is a detailed analysis of this issue: The importance of 1. air compressors Air compressors are indispensable key equipment in many industrial and commercial applications. It
