Chemical fertilizer industry has a decisive effect on China's agricultural development, especially the production of phosphate fertilizer is an industry supported by the key points in the micro regulation and control of national economy in China. Therefore, large and super large water ring vacuum pumps have also been used here. For example, a phosphate fertilizer enterprise in Yunnan Province added three extra large water ring pumps with pumping capacity of 300m3 / min after one transformation.
In addition, there are many phosphate fertilizer enterprises that still need to have greater ability to pump air when the absolute pressure is 80 ~ 100hPa. However, the vacuum degree of a single water ring vacuum pump is 3300 PA, which can not meet the process requirements. However, if an atmospheric injector is added in front of the water ring pump, the vacuum degree will get certain progress and have common advantages.
It was found in the telephone consultation of many chemical fertilizer enterprises that the reciprocating vacuum pump they used before was gradually screened out because of the large number of vulnerable parts and high noise. The double-stage water ring vacuum pump was replaced by the double-stage water ring vacuum pump, which has achieved good results. According to the practical experience, the double-stage water ring vacuum pump will be used more and more widely in this profession.
