What are the advantages and disadvantages of self-priming pumps?
We all know that the perfect things have its advantages and disadvantages, the same applies to self-priming pumps, we all know that self-priming pumps are in the oil refining, chemical production, pharmaceutical production and other fields are With a wide range of equipment, the research on the advantages and disadvantages of self-priming pumps is of great importance as the frequency of use of such products continues to increase. Self-priming pump self-priming pump Advantages: 1, sewage capacity: a special impeller anti-blocking design to ensure efficient and non-clogging pump. 2, energy efficient: the use of excellent hydraulic model, the efficiency of the general self-priming pump 3 - 5%. 3, good self-priming performance: self-priming height than the general self-priming pump 1 meter, and the self-priming time is shorter. Disadvantages of self-priming pump: 1, ambient temperature ≤ 45 ℃, medium temperature ≤ 60 ℃. 2, medium PH value cast iron pump is 6--9, stainless steel self-priming pump is 1--14. 3, through the largest particle diameter of 60% of self-priming pump diameter, fiber length of 5 times the caliber. 4, the total weight of impurities in the media does not exceed 15% of the total weight of the media, the proportion of media does not exceed 1240 kg / cubic meter. Through the analysis of the above points, we can know very clearly that the self-priming pump is a kind of sewage-discharging capability, self-priming performance and energy-saving equipment, but at work also need to meet certain conditions, although these products are flawed , But the flaw does not cover the yu, the use of self-priming pump has still been affirmed by everyone, I believe in the future, through the efforts of all walks of life, such products will certainly have a better future.
