当前在炼化行业中机械密封已经被广泛应用于各种泵类产品之中,包括催化裂化油浆泵、常压塔底泵、回炼油泵、以及初馏塔底泵、延迟焦化的辐射进料泵、减压塔底泵等多种。因此,泵用机械的密封方式是否有效合理的选择直接关系到设备本身的寿命。本文针对炼化行业的泵用机械密封主要特点进行分析,指出可能导致密封效果失效的几种常见因素,并以此为主要问题进行了分析探索,并提出相关的解决建议。 Current mechanical seals in the refinery industry have been widely used in a variety of pump products, including catalytic cracking slurry pumps, atmospheric tower pumps, reboiler pumps, and head pump, delayed coking radiation Material pump, vacuum pump at the end of a variety of other. Therefore, the pump mechanical seal is effective and reasonable choice is directly related to the life of the device itself. This paper analyzes the main characteristics of pump mechanical seals in the refining industry, points out several common factors that may lead to the failure of the sealing effect, and analyzes and explores the main problems, and puts forward some solutions to the problems.
