炼油厂的离心泵是为数最多的转动设备。以我厂七套炼油生产装置为例,离心泵占整个生产用泵的84.4%。因此离心泵能否正常运转,决定着生产装置能否安全、平稳地生产,决定着环境污染及能耗。离心泵工作的好坏,很大程度上又取决于轴封的工作状况。根据七套装置离心泵轴封的统计,机械密封占90.4%,填料密封占9.6%。机械密封的维修工作量最大。曾对六
The refinery centrifugal pump is the largest number of rotating equipment. Take our factory seven sets of oil refining production plant as an example, centrifugal pumps accounted for 84.4% of the entire production pump. Therefore, the normal operation of the centrifugal pump determines the safe and stable production of the plant, which determines the environmental pollution and energy consumption. Centrifugal pump work is good or bad, largely depends on the working conditions of the shaft seal. According to the seven sets of centrifugal pump shaft seal statistics, mechanical seal accounted for 90.4%, packing seal accounted for 9.6%. Mechanical seal maintenance workload of the largest.
