First of all, we should understand the air compressor. It is well known that an air compressor is a device that converts kinetic energy by compressing and pressurizing air. The classification of air compressors is based on the principle, capacity, and cooling methods. For example, air compressors classified by capacity can be classified into low-capacity air compressors, medium-capacity air compressors and high-capacity air compressors. According to the design and working principle, air compressors can be classified into reciprocating type. Compressors and rotary compressors can be divided into single-stage air compressors and multi-stage air compressors according to the number of stages. According to the pressure classification, they can be divided into low, medium, high and ultra-high pressure air compressors. For cooling types It can be divided into two types: pneumatic cooling and water cooling.
Next, let’s talk about which air compressor is more suitable for pneumatic tools. The maximum efficiency of an axial air compressor can reach about 90%. Behind its high efficiency, a large number of original parts and high-quality materials are required, and the cost is relatively expensive. , Generally used in medium to large gas engines and natural gas stations or some chemical plants. Reciprocating air compressors can be fixed and easy to carry. Small reciprocating air compressors ranging from 5 to 30HP are usually used for portability. In large industrial or petroleum applications, they are usually large reciprocating air compressors of more than 1000HP. The family or small-scale skills are usually 1.5HP with an additional gas storage tank type. The screw air compressor is most often used in commercial and industrial continuous operation. Its horsepower can be between 3HP and 1200HP and can also work at low or high pressure (up to 1200PSI).
In the compression ratio, the axial centrifugal air compressor is used in commercial applications with a compression ratio of no more than 3.5:1. The heat generated by compression lacks heat insulation and cooling in the multi-temperature stage, which usually leads to local condensation. The air compression ratio of screw air compressors can often exceed 9:1, which is why screw air compressors are widely used in commerce and industry. Due to the large air compression ratio, it can maintain the pressure stability by carrying a suitable air tank. According to the requirements, it is usually required that the air volume of the air compressor should be about 20% higher than that of the pneumatic tool. However, due to the limited conditions, the continuous output capacity of various types of air compressors is limited, and the screw air compressor that can maintain the output ratio is considered more suitable. Working now.
Stable pressure and air volume can keep the pneumatic tool in the working state of rated power, which can maintain the torque accuracy of the pneumatic tool, and reduce the irregular rotation caused by the speed change of the blade inside the pneumatic tool, which can also greatly reduce the loss of the blade. . The most important point is that pneumatic tools will not be overloaded due to the reduction of pressure and air volume under stable air pressure. Overload work often exceeds people’s expectations for the degree of wear on the driving parts, blows and transmission parts of pneumatic tools. Reasonable selection of air compressors and pneumatic tools will increase your work efficiency a lot, ELANG air compressor is your best choice.
