Description
Technical field
The present invention relates to a kind of reciprocating pump fillers, more particularly, to a kind of reciprocating pump suitable for high-temperature medium
Packing seal structure.
Background technology
Reciprocating pump needs to prevent the dielectric leakage of conveying from coming out, common closed type come sealing medium by filler
Formula has reinforced seal, jam type packing sealing, and band spring-loaded packing seals, and pre-tightens V-type packing seal certainly.It is general reciprocal
For plunger pump when conveying high-temperature medium, common seal style reinforced seal can be by the temperature shadow of media particle and medium
It rings, and the service life is greatly reduced, and once leakage is only replaced, the service life 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 from the excessive reduction leakage rate of having no idea of V-type packing seal leakage is pre-tightened later, can only replace, in this way meeting
According at replacing frequently, the replacement of user scene is fairly cumbersome, and operating cost is high and less efficient.
Because the operating mode type 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, soft seal can be used, 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 performance, but use is in high-temperature medium, it will be due to thermally expanding, and cause largely to leak, preceding two can only be compressed by usually pre-tightening
The sealing of ring, can not homogeneous compaction, cause airtight and watertight padding to damage again quickly.
Invention content
It is situated between it is an object of the present invention to overcome the above-mentioned drawbacks of the prior art and provide one kind being suitable for high temperature
The reciprocating pump packing seal structure of matter, the present invention use the sealing of special filler compacting part and special shape
Part, it is comprehensively uniform to adjust filler crush according to the temperature of medium so that seal member even wearing, mean forced increase
Its service life improves operability, improves the safety and reliability of operation.
