Packing seal by packing installed in the stuffing box inside, through the packing gland will packing gland in the surface of the shaft tight. Because there are always some rough surface shaft, and with the packing can only be one part joint, and some of the form is not contact, countless maze. When take pressure media through the shaft surface, medium to be DuoCi throttling and with this "maze effect" and to seal. Packing and axis of joint, friction surface, also similar sliding bearing, solid should have enough liquid for lubrication, to guarantee seal have a certain life, the so-called "bearing effect". This shows good packing seal, which is a labyrinth effect and bearing the comprehensive effect. Packing in shaft of compaction force through the tight gland bolts generated. Due to packing is elastic and plastic body, when receiving the axial pressure and caused the friction cause compaction force along the axial gradually reduce and, at the same time, the pressure generated radial force to close on a shaft surface and packing stop medium outside leakage. Radial compaction force distribution from the end (gland) to the sharp decline in, first is gentle, after media pressure from within the distribution of the outside gradually to the descending, when the medium pressure, the zero leakage rarely, is zero while leakage. With the new material appear constantly, packing structure type also have very big change, no doubt will prompt the packing seal more widely used for packing, the material should be has following features: there are certain elastic-plastic. When packing by axial pressure can produce larger when radial compaction force to get seal; When the machine and shaft vibration or shaft have to beat a and eccentric, can have certain compensation ability (follow sex); The chemical stability. Neither is medium corrosion, dissolve rise, nor pollution medium; Don't permeability. Medium for most fibers are some penetration, the requirements for compact structure, packing in making packing, often need dipping, filling various lubricant and filling agent; Since the lubrication and good small friction coefficient and wear-resisting; Resistant. When friction fever can bear a certain temperature after; Remove the convenient; Making simple, low price.
