La description
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.
