Precautions for the selection of air compressor tank

Brief introduction of air compressor tank:

　　 Air storage tank is a kind of industrial equipment commonly used in industry to purify and compress air, and it is also one of the special safety equipment strictly regulated by the country. The gas storage tank is a pressure vessel, which is produced by a designated factory for the pressure vessel, each with a vessel inspection certificate, safety valve, drain valve, pressure gauge and other accessories.

The function of air compressor tank:

The gas storage tank can be used in combination or a single unit; it can reduce the pulsation of the air flow discharged by the piston air compressor; improve the continuity and pressure stability of the output air flow; further precipitate and separate the water and oil in the compressed air ; Ensure continuous supply of sufficient air volume. It can be used in combination or single.

　　 Principle of air compressor tank:

Moisture-the relative humidity in the atmosphere is generally as high as 65% or more. After being compressed and condensed, it becomes wet and saturated air and entrains a large number of liquid water droplets. They are the root cause of corrosion of equipment, pipes and valves. In winter, freezing will also block Small hole passage in pneumatic system. It is worth noting that even if it is separated and clean pure saturated air, as the temperature decreases, there will still be condensation water. About every 10 ℃ decrease, its saturated water content will drop by 50%, that is, half of the water vapor conversion It is a liquid drop. Therefore, it is necessary to use a multi-stage separation filter device in the compressed air system or to pre-process the compressed air into dry air with a certain relative humidity.

　　 Suggestions for correct selection of air compressor tank:

Nowadays, there are many brands of gas storage tanks on the market. Due to the high safety factor requirements for such products, in order to ensure safe and reliable use, it plays a vital role in the selection of gas storage tanks. What will happen now? Select and purchase a safe and secure gas storage tank for the following brief instructions:

　　 First, choose the products of large enterprises and well-known brands. The products of these companies not only strictly implement the GB150-98 "Steel Pressure Vessel" standard, but also form their own corporate standards. At the same time, these companies have advanced production equipment, strict production process management, and good quality raw materials. Although the prices of the products of these companies may be relatively expensive, they can guarantee the products when they are used, and use them with confidence. In addition, products produced by companies that have passed multiple quality system certifications are also preferred.

　　 The second is to look at the appearance. The appearance of the product reflects its grade and value. Only formal and powerful manufacturers have advanced equipment guarantees and a good quality assurance system to ensure the grade of the appearance of the product. The trademark of a high-quality gas storage tank is very obvious, and the brand of the gas storage tank can be clearly known 50 meters away from the gas storage tank. Approaching the gas storage tank, the tank itself has bright color, uniform surface treatment, flat welds and clear lines, so it is best to buy new products.

　　 The third is to look at the product nameplate. The nameplate should indicate the name and production date of the manufacturer and supervisory inspection unit, and whether there is a seal of the supervisory inspection unit in the upper right corner of the nameplate, and the product number, weight, volume, and load must be indicated on the nameplate. The highest pressure, working pressure, and the pressure of the water pressure test, the medium of the gas storage tank must also be marked. The steel stamp number of the product must be directly under the nameplate of the entire tank, and the stamp number must be consistent with the number on the nameplate. Found that the two numbers are inconsistent, it is best not to buy.

　　Fourth is to read the quality assurance certificate. According to relevant national regulations, each gas storage tank must be accompanied by a quality assurance certificate when leaving the factory. The quality assurance certificate is an important document to prove that the gas storage tank is qualified. If there is no quality assurance certificate, even if the price It is safe to use, please do not buy it.

　　 The fifth is to look at the qualifications of the manufacturing company. A strong brand-name enterprise, the qualifications and honors it possesses are not comparable to ordinary enterprises. Although some small companies have manufacturing licenses for pressure vessels, the overall equipment is outdated and the management is not very standardized. The gas storage tanks produced are prone to safety hazards. Therefore, if ordinary users want to purchase, it is best to have a more comprehensive understanding of the All aspects of the company’s qualifications to avoid unnecessary trouble.
