Technical field
A kind of reciprocating pump filler is the utility model is related to, more particularly, to a kind of past biprism suitable for high-temperature medium
Fill in pump packing seal structure.
Background technology
Reciprocating pump is needed by filler come sealing medium, and the dielectric leakage for preventing from conveying comes out, conventional closed type
Formula has reinforced seal, jam type packing sealing, and band spring-loaded packing seals, and from pretension V-type packing seal.It is general reciprocal
For plunger pump when high-temperature medium is conveyed, conventional seal style reinforced seal can be by media particle and the temperature shadow of medium
Ring, and the life-span is greatly reduced, and once leakage is only changed, the life-span is very short；Jam type packing sealing can be by high temperature and pressure
It is excessive that power influences short time internal leakage, pre- next excessive, band spring loads that would generally occur leakage rate again in a short time
Packing seal, and have no idea to reduce leakage rate later from pretension V-type packing seal leakage is excessive, it can only change, so meeting
According into changing frequently, the replacing of user scene is fairly cumbersome, and operating cost is high and less efficient.
Because the operating mode species that reciprocating pump is conveyed is relatively more, containing miscellaneous especially in high-temperature field, pumped (conveying) medium
Matter contains particle and molten condition itself, all determines in packing seal, can use soft seal, without using hard sealing.
Common soft sealed packing such as graphite packing, aramid fiber packing, compression performance is high, has well for the medium of non high temperature environment
Sealing property, but use is in high-temperature medium, will be due to thermal expansion, and cause largely to leak, usual pretension can only compress preceding two
The sealing of ring, can not homogeneous compaction, cause airtight and watertight padding to damage again quickly.
