In the compressed air system, a system composed of equipment that generates, processes, and stores compressed air is called the gas source system. The screw -type air compressor compression is first obtained by compressing the air by air compressor. In the air source system, the air directly discharged from the air compressor contains a lot of impurities. It is treated and used directly. The impurities in the air will cause great damage to the components in the system, which will increase the protection cost of the equipment, shorten the life span, and severely pollute the commodity scrap. The compressed air contains a relative humidity water. Following the cooling of its pipeline, its water is split. In the compressed air system, if there is water, it will bring a lot of disadvantages to the user:
First of all, it is necessary to increase the cost of work and repair, that is, the repair cost of the surface, the solenoid valve, the cylinder and other components will increase; the operational efficiency of the equipment is low, and there may be an interruption of production. Adding condensate, separation, sewage and other equipment; skill quality, especially about the industries such as paint paint, sandblasting, pneumatic control system, food, pharmaceutical and other industries. Due to the high moisture content of compressed air, it will directly affect the quality of the product. Therefore, it is necessary to deal with gas sources. The purification treatment equipment of the air is mainly based on the rear cooler, fine filter (including gas separator), dryer (adsorption or frozen), and active drainage and sewage valve to form a good system based on different skills. In industrial production, the dullness of compressed air is usually represented by the dew point temperature. The dew point refers to the temperature when the water steam is cooled from the beginning of cooling, and the temperature changes from the steam to liquid. The air condition of the air when the temperature is 20 ° C and the relative temperature is 65%. The air density is 1.2kg/m3 (air compressor exhaust, boring machine, filter and other post -processing equipment under the standard state. The amount is marked by the flow of air specifications.
