The role of chemical fertilizers in agricultural production is obvious to all. It accounts for 40% to 60% of the increase in crop yields. People often say that there is no food, no food, no more grain, and less fertilizer, but this is not exactly the case. . Some peasant fertilizers are not used less but the output is not high or the yield is high and the income has not increased much. This is because crops need different nutrients. Different types of soil have different amounts of fertilizer. Fertilizer is not applied as much as possible. Blindly applying too much wastes fertilizers, increases production costs, decreases production, and reduces returns. The application of a soil tester has provided great help for fertilization.
For these problems, people are proposing a soil testing instrument for soil testing and fertilizer application. Practice has proved that the promotion of soil testing and formula fertilization technology can increase the utilization rate of chemical fertilizers by 5%. The rate of increase in O% is generally 10% to 15%. The high rate of up to 20% can save the cost by 10 to 20 yuan. The implementation of soil testing and formula fertilization can not only increase the utilization rate of chemical fertilizers to achieve cost-effectiveness and efficiency, but also ensure stable yields and high yields. It can also improve the quality of agricultural products, and realize the balance between cultivating cultivated land and fertilizing the soil. This is a technical measure to increase production, save fertilizer and reduce expenditures. .
It is well-known that the application of chemical fertilizers once brought about an agricultural revolution, and the implementation of soil testing and formula fertilization undoubtedly brought about another agricultural revolution. However, the use of soil testing instrument for soil testing and formula fertilization technology has been used in China for many years since its introduction in the 1980s. However, this revolution has yet to form a prairie fire. The coverage rate in the country is only about 30%.
The oil-gas Separation Filter is a device that separates the micro oil droplet to ensure that the lubrication system can work well and almost no micro oil droplet goes out of the air flow of the compressor . Applications: Solid-liquid, gas-solid, gas-liquid separation and purification in the fields of petroleum, chemical, metallurgy, aviation, electronics, power, pharmaceutical, environmental protection, atomic energy, nuclear industry, natural gas, refractory materials, fire-fighting equipment, etc.
The air from the compressor mains is filled with oil droplets of different sizes. Large oil droplets are easily separated by the oil-gas separation tank, while small oil droplets (suspended) must be filtered by the oil-gas separation filter. The correct choice of glass fiber diameter and thickness is an important factor to ensure the filtration effect. After the element filtered, the small oil droplets are quickly polymerized into large oil droplets, which go to the bottom of the Filter Element. These oils are returned to the lubrication system through the inlet of the return line at the bottom of the filter element, allowing the compressor to discharge relatively pure, high-quality compressed air.
