tepi yepolymer imhando yakasarudzika yetepi inoshandiswa mupombi yekusimbisa kubatanidza zvakakwana, kuve nechokwadi chekuti mapaipi haabvire.Iyi tepi inonzi zvakare poly(tetrafluoroethylene) (PTFE) tepi, nepolymer iri chiratidzo chekambani yeDuPont.
PTFE chinhu chinonakidza kwazvo.Kubva pakuona kwepombi, zvakakosha kuti uzive kuti inoshanduka-shanduka uye ine simba rakakura kwazvo.Kana tepi yepolymer inoshandiswa kuputira tambo dzepombi, tepi inoita kunge putty, ichizadza nzvimbo uye kudzivirira kubuda.Kunyange zvazvo zvichibvira kushandisa pombi putty kumabasa akadai, tepi yepolymer inokurumidza uye iri nyore, uye kazhinji yakachena zvikuru, zvakare.
Kazhinji,PTFE tepiichena, nokuti iri ndiro ruvara rwechisikigo chechinhu.Mamwe makambani anogadzira tepi yePTFE ine mavara ane mavara akasiyana ari kugadzirirwa marudzi akasiyana epombi.Iyo tepi yepolymer inoshandiswa kugadzira gasi pombi dzemvura, semuenzaniso, yakakora kudzivirira kubuda kwegasi, uye inogona kunyorwa bhuruu kana yero.Iyo tepi haina kunamatira, inonamira kunamatira nekumanikidza asi iri nyore kufamba uye kumisazve.
Iyi tepi yakagadzirirwa kushandiswa mumapombi ane tapered threads.Mapombi ane tape akanakira kugadzira chisimbiso chakasimba nekuti iyo tapered dhizaini inogadzira wedge mhedzisiro, kuvhara pombi zvakanaka kuti hapana chinobuda.Kuti ushandise tepi, kureba kunoputirwa kumativi echirume kana kuti threaded kuguma kwepombi, uye ipapo kuguma kwechikadzi kwepombi kunobatanidzwa.Zvakakosha kuve nechokwadi kuti tepi yepolymer haina kupindirana nekuguma kwepombi, sezvo izvi zvinogona kukonzera matambudziko mune ramangwana, nokuti tepi inogona kuvhara pombi.
tepi yepolymer chinhu chinobatsira kuchengetedza imba.Kunyange kana mupfuri wepombi akabvunzurudzwa kuti agadzirise dambudziko, tepi inogona kushandiswa kugadzirisa nekukurumidza kuchengetedza zvinhu kusvikira mupumba asvika.Vanhu vanofanirwa kungwarira zvakanyanya pamusoro pepombi dzegasi, sezvo kubuda kwegasi kunogona kuve nengozi, uye kunofanirwa kubatwa nenyanzvi.Kana gasi rinoputika richifungidzirwa, gasi rinofanira kudzimwa uye nyanzvi yegesi inofanira kushevedzwa pakarepo.
Iyo PTFE Inoshanda sei
Zvikasadaro inozivikanwa seshinda chisimbiso tepi, PTFE tepi inoshandiswa pamucheto wechirume wepombi (inozivikanwa seshinda) isati yabatanidzwa kune mamwe mapaipi.Iyi firimu yakagadzirwa kubva ku polytetrafluoroethylene (PTFE), yakagadzirwa zviri nani sepolymer.Nekuda kwekuti chinhu ichi hachipindike uye chinoumbika, chinoumba kuita chinhu chakafanana neputty mushure mekunge chaputirwa neshinda dzepombi uye chakapindirwa mune mamwe mapaipi.Iko kukweshana kunokonzerwa nekukochekera mapaipi pamwe chete kunomutsa tepi yeshinda, kugadzira chisimbiso chisina mhepo uye chinova nechokwadi chekuti mapaipi akabatanidzwa zvakanaka.
PTFE tepi inongoshanda patambo dzakatemerwa kupesana neshinda dzakafanana.Izvi zvinodaro nekuti tepi inoshanda kubva pane friction yakagadzirwa netambo dzakatemerwa.Thread tepi inoshanda sechisimbiso nekuti inozvinatsa pachayo sezvo ichisangana nekukweshana.Kushandisa tepi yePTFE yakawandisa kunogona kukuvadza, sezvo zvinhu zvakawandisa zvinogona kubuda kunze kwepombi, zvichiburitsa pachena makemikari anokuvadza.
Kushandisa PTFE Tape
Chinhu chakakosha chePTFE tepi kuita chokwadi chekuti unoshandisa huwandu hwakakodzera.Iyo yakakwana yakawanda inosvika kaviri kutenderedza pombi mune yakatarisana nzira yeshinda.Kana iwe ukaona kuti wakaisa zvisizvo tepi yeshinda uye kubatana kwepombi kwakakombama, unogona kuzviwana uine mamiriro akaoma.Mapombi anogona kunge akanyanya kusimba kuti asakurura.Nekudaro, iwe unogona kugadzirisa izvi nekubvisa chigadziriso chine pombi uye nekunamatira screwdriver mukubatanidza uye kuivhura.
Mhando dzePTFE Tape
PTFE tepi inouya mune akasiyana mavara, density uye ukobvu.Kune ekutanga mapurojekiti epombi, iwe unozokwanisa kushandisa mureza, chena PTFE tepi.Nekudaro, kune mitsetse yegesi uye basa rine njodzi, imwe yakasarudzika mhando yetambo tepi inogona kudikanwa.Rudzi rwe tepi harukanganisi kuita kwayo, asi rinogona kusarudzwa zvichibva pamavara epombi yako.Pane zviyero zviripo zvinotaridza kurongeka kwePTFE tepi, uchifunga nezvezvinhu zvakaita sehupamhi uye density.
