Dry Pump Fertilizer Industry

Imported vacuum pumps are also widely used in chemical fertilizer industry, especially in the production of phosphate fertilizer, which is also a key support industry in China's macro-economic regulation and control. Large and super-large water-ring vacuum pumps are also used here, because the technological transformation of new projects and old enterprises are all above the level and scale. For example, a phosphate fertilizer enterprise in Yunnan has increased its pumping capacity by 3. Three super large water ring vacuum pumps of 00m3/min.


In addition, there are many phosphate fertilizer enterprises that require large pumping capacity when the pressure is 80-100 hPa. Therefore, two-stage water-ring vacuum pump and two-stage water-ring vacuum pump with atmospheric ejector have unique advantages when used in this condition. Many fertilizer enterprises have eliminated the reciprocating vacuum pump with high vibration noise and high vacuum, and used two-stage water-ring vacuum pump. It can be said that the two-stage water ring vacuum pump will be more and more widely used in this industry.


At present, domestic vacuum pump acquisition equipment is still dominated by traditional vacuum pumps, mainly rotary vane vacuum pumps, water ring vacuum pumps, sliding valve vacuum pumps, Roots vacuum pumps, and all of them are used in traditional industries. Vacuum pumps produced in China are more and more widely used in electronic information industry, narrowing the gap with Japan, Europe and the United States and other countries.


Most of the dry pumps produced by EVP vacuum pump manufacturers are used in laboratory, chemical, pharmaceutical and other fields, and also in semiconductor industry. The rapid development of electronic information industry in China has a useful impact on the development of domestic dry vacuum pumps.


After all testing of the vacuum pump, on the basis of increasing its progressive operational specifications, it is necessary to show the useful promotion of the product's ability to complete its application, to strengthen the continuous improvement of the quality of the vacuum pump, to have a strong production advantage, to carry out the application of all the stock products, to expand the different levels of application, and to increase the overall promotion of the product with rapid and stable operation. Usefulness, further implementation of the full performance of all functions, corresponding to the different needs of the company, reasonable skill development of products.


The practice of imported vacuum pumps has its advantages in order to speed up its function promotion and enhance its productivity. Only with excellent skills can we improve the development of the overall application, promote the strict management of various processes, and increase the demonstration of the practical role of product application, can we fully prove its ability to carry out, and will continue to share its advantages in the development process. Expanding the performance of its total use value, and increasing the useful assistant to the production operation with the full production capacity.


From different industries, it can show the advantages of imported vacuum pumps. Through high standard product quality, it can effectively promote its continuous development ability. With the advantages of rapid and stable development, it can share the promotion of all its use ability, and increase the further expansion of quality.
