Analysis of Damage Causes and Maintenance Points of Dynamic Seals for Pumps


1. Analysis of the actual situation: K-type dynamic seal is a commonly used shaft seal for anti-corrosion slurry pumps. Its advantages are: first, simple structure, low maintenance technical requirements, easy to use; second, good versatility, both suitable for clear liquid, It is also suitable for the transportation of slurry; third, it has good anti-corrosion performance, and can be used in almost all kinds of corrosive media. But there is also a big disadvantage: easy to leak. Judging from the leakage situation, the first leakage time is 15~50 days, mainly distributed in the positions that pressurize and convey the slurry, such as the feed pump of the filter press; the first leakage time is 5~6 months. The result of statistical analysis is that the positions are distributed in the circulation of conveying materials at atmospheric pressure, and most of them belong to this situation (generally, the actual working pressure is below 80% of the design pressure of the pump, for example, the rated design pressure of the pump is 0.5MPa, and the actual working pressure is 0.4 MPa. Posts below MPa); there are also posts where the first seal leakage occurs in about a year. Most of the conclusions drawn through research and analysis are distributed in posts where clear liquid is transported and the operating pressure is lower than the design pressure, such as sulfuric acid engineering purification. Dilute acid circulation pump in the system. According to the comprehensive analysis of the above situation, we found that the life of K-type dynamic seal is mostly related to the operating pressure.
