Sealing Principple thiab Txheej Txheem Ua Haujlwm
Kev sib dhos theem: FKM O-ntiv nplhaib raug ntsia rau hauv ib qho ua ntej -machined duab plaub lossis trapezoidal zawj. Thaum kaw cov khoom, cov phab ntsa groove exert ib tug predetermined tus nqi ntawm compression ntawm lub O- nplhaib (static foob compression: 15% -30%; reciprocating dynamic foob compression: 10% -20%; teb dynamic foob compression: 5% -12%).
Sealing Formation Phase: Nyob rau hauv compression, elastic FKM matrix undergoes elastic deformation, tag nrho cov microscopic khoob ntawm qhov zawj thiab cov mating hlau los yog yas qhov chaw los thaiv cov xov xwm permeation paths. Raws li kev tshaj tawm siab nce, O-ntiv nplhaib raug yuam mus rau qhov qis- siab ntawm qhov zawj, ntxiv kev sib cuag nrog kev ntxhov siab ntawm qhov sib cuam tshuam thiab tsim kom muaj kev sib khi rau tus kheej.
Kev ua haujlwm tsis tu ncua: Nyob rau hauv cov xwm txheej ntawm qhov hloov pauv siab thiab qhov kub thiab txias, cov khoom siv FKM tswj tau qhov ruaj khov elastic modulus thiab kev sib cuag tsis tu ncua. Thaum lub kaw lus kaw thiab depressurization, cov khoom rov qab los ntawm nws qhov qub annular cross-section los ntawm nws cov elasticity; qhov tsis muaj cov yas deformation mus tas li ua kom muaj kev ruaj ntseg sealing thaum lub sij hawm reassembly.
Kev txwv tsis pub dhau: Kev sib cuag kev ntxhov siab tsis ua tiav thiab cov xov xwm xau tshwm sim thaum cov txheej txheem compression tshaj 25%, cov xov xwm o ntawm tus nqi siab tshaj 15%, los yog nto tawg los yog hardening tshwm.
