炼油厂白土精制装置的白土泵密封属颗粒密封,而颗粒密封是密封方面的一个薄弱环节。尤其对于高温下的悬浮颗粒密封:一方面要消除高温下密封失效的因素;另一方面又要防止悬浮颗粒对密封的危害。
Clay clay refinery white clay pump seal is a particle seal, and particle sealing is a weak area of the seal. Especially for high temperature suspended particles sealing: on the one hand to eliminate the factors of high temperature seal failure; the other hand, to prevent the suspended particles on the seal of the harm.
