Ichi chingakhale chinthu chofunikira, koma kukwanitsa kupopa matayala a njinga ndi luso lofunikira kwa woyendetsa njinga aliyense.
Ambiri a inu mumadziwa kale momwe mungachitire izi, koma kwa iwo omwe sadziwa, mitundu yosiyanasiyana ya ma valve, mapampu, ndipo chofunika kwambiri, kupanikizika kwa matayala kungakhale kovuta kwambiri. Tiyeni tikutsogolereni munjirayi.
Kupopera matayala ndi ntchito yachangu ndipo kungakulitse chisangalalo chanu chokwera. Kuthamanga kolakwika kwa tayala kumatha kusokoneza momwe njinga yanu imakwerera komanso kungapangitse kuti njinga yanu ikhale yovuta kwambiri kuphulika.
Ngati simunakonzepo choboolapo, mwina simunaganizirepo za momwe mungasungire mpweya mkati mwa tayala.
Njinga zambiri zimagwiritsa ntchito machubu amkati. Ichi ndi chubu chopanda mpweya chofanana ndi donut, chomwe chili mkati mwa tayala, chokhala ndi valavu yoponyeramo, yomwe mumatha kuona kuchokera kunja.
Tayalalo litakwiriridwa ndi chubu, limamatirira pansi ndikuteteza kuphulika.
Mwina munamvapo za matayala opanda machubu, omwe amasiya machubu amkati ndikugwiritsa ntchito machubu apadera ndi matayala kuti atseke mpweya wopanda machubu amkati. Izi nthawi zambiri zimafunikira chosindikizira chamkati cha tubeless, madziwa amatsekereza malo aliwonse omwe mpweya umathawira.
Matayala opanda chubu amapezeka kwambiri panjinga zamapiri, koma ukadaulo umasamukira ku njinga zamsewu.
Tubeless sealant imathanso kutsekereza ma perforations, ndipo kusakhalapo kwa chubu chamkati kumatanthauza kuti chiwopsezo cha flatten ndi chotsika kwambiri - ndiko kuti, chubu chanu chamkati chikafinyidwa ndi mkombero, zimayambitsa kubowola. Chifukwa chake, matayala opanda machubu amatha kuthamanga pamitsempha yocheperako kuposa matayala a chubu kuti apititse patsogolo chitonthozo, liwiro komanso kuyenda.
Pamapeto apamwamba kwambiri, mutha kupezanso matayala a tubular. Ili ndi tayala lokhala ndi chubu chamkati, koma sawoneka kapena kugwiritsidwa ntchito kunja kwa mpikisano wa akatswiri.
Kuthamanga matayala pakukwera kwambiri kapena kutsika kwambiri kungakhale koopsa komanso kusokoneza kagwiridwe ka njinga.
Tidzakambitsirana za chitsenderezo choyenera pambuyo pake, koma tsopano tiyeni tione mavuto omwe angakhalepo.
Ngati mutayendetsa matayala motsika kwambiri, matayala amatha kutha msanga. Kupindika kwambiri kwa khoma la m'mbali kungachititse kuti chotchinga cha matayala ching'ambe komanso kuti tayalalo liwonongeke. Izi zitha kubweretsa kuphulika.
Kuthamanga kotsika kwambiri kumawonjezeranso chidwi chanu pakubowola, ndipo kumatha kupangitsa kuti matayala anu agubuduke pamphepete mukatembenuka mwachangu (kuthamanga kwamkati ndiye chifukwa chokonzera tayala pamphepete).
Ngati tayalalo lapatuka mpaka kufika pamphepete, likhozanso kuwonongeka. Izi zingayambitse ming'alu kapena ming'alu, zomwe zingawononge magudumu anu ndikuyambitsanso zodula.
Komanso, kupanikizika kwambiri kungachititse kuti matayala anu atuluke m'mphepete mwake, zomwe zingakhale ndi zotsatira zophulika. Kupanikizika kumeneku kudzakufinyanso gudumu, chifukwa ngati kuthamanga kuli kwakukulu, kuthamanga kwa gudumu kungakhale kokwera kwambiri.
Pankhani yogwira, kutsika kwapansi kumapangitsa kuti matayala aziyenda pansi pa katundu, motero amakhudza kagwiridwe. Njinga yanu idzamva kukhala yosalamulirika, yodekha komanso yaulesi.
Kumbali inayi, kupanikizika kwakukulu kumapangitsa kuti kuchepetsa kugwidwa ndi kukwera kosakwanira, zomwe zimabweretsa kutopa, zomwe zimakhudza kugwira ntchito.
Pali zifukwa ziwiri zomwe tayala laphwanyika. Mwina mwabowoledwa, kapena tayala lanu laphwanyidwa pakapita nthawi.
Zigamba zopanda zomatira ndizabwino kukonzanso mwachangu, ndipo mukakhala ndi nthawi yochulukirapo, zida zachikhalidwe ndizosankha zambiri.
Matayala onse amataya mpweya pang'onopang'ono chifukwa chubu lamkati silimamatidwa. Mwachitsanzo, poyerekezera ndi machubu opepuka a latex, machubu a raba a butyl amatha kusunga mpweya bwino, ndipo machubu omalizira amawuka msanga. Ngakhale chipangizo chopanda chubu chidzatulutsa mpweya pang'onopang'ono.
Mapaipi akale adzatulutsa mpweya wochulukirapo kuposa mapaipi atsopano, kotero ngati mapaipi anu sanasinthidwe kwakanthawi, atha kukhala oyenera kuyang'ana. Ndizokayikitsa, koma ndizotheka (makamaka pa mapaipi akale) kuti valavu sichimasindikizanso bwino.
Njira yabwino yowonera zomwe zikuchitika ndikuyesa kupopa matayala. Ngati imasunga mpweya, ndiye kuti simungafunike kuchita zambiri. Ngati sichoncho, ndiye kuti mutha kukhala ndi puncture.
Ngati idontha pang'onopang'ono usiku wonse, mwina liwiro lanu lobowola limachedwa, kapena ndi chubu lakale lomwe likufunika kusinthidwa.
Vavu ndi chinthu chofunikira kwambiri kuti mpweya ukhale mu tayala, komanso imakulolani kuti mufufuze (kapena kuchepetsa) tayalalo.
Ma valve a Schrader amapezeka kwambiri panjinga zotsika komanso panjinga zam'mapiri zakale. Valve yomweyi imagwiritsidwanso ntchito pamatayala agalimoto.
Msonkhano wa valavu ndi chubu chopanda kanthu chokhala ndi valavu ya masika yomwe imatha kutsekedwa ndikumangirira mu thupi lakunja la valve. Pini imakwera mmwamba kuchokera ku valve, nthawi zambiri imatuluka kumapeto kwa chubu chakunja. Pini iyi ikhoza kukanikizidwa kuti itulutse mpweya.
Chophimba cha fumbi pa valve ya Schrader ndi gawo lofunika kwambiri la mapangidwe. Ngati valavu sisindikizidwa kwathunthu, ikhoza kuthandizira kusindikiza kwathunthu valve. Zimapereka chisindikizo chachiwiri "zosunga zobwezeretsera".
Mapangidwe a kasupe a valve amatha kuipitsidwa ndi fumbi kapena grit, choncho ndikofunikanso kuteteza.
Iwo anachokera ku njinga zapamsewu, kumene mavavu ocheperako (6mm vs. 8mm kwa Schrader) amatanthauza kuti pali mabowo ang'onoang'ono a valve pa mawilo opapatiza (nthawi zambiri mbali yofooka ya mkombero).
Masiku ano, amatha kuwoneka panjinga zamapiri ndi njinga zamsewu. M'malo mogwiritsa ntchito kasupe, valavu imayikidwa ndi nati kuti valavu ikhale yotsekedwa, ngakhale kuti valavuyo yokha "idzasindikiza" pamene kuthamanga mkati mwa tayala kutseka.
Kwa mavavu a Schrader, mumangofunika kukanikiza pini kuti mutulutse mpweya, koma mavavu a Presta, choyamba muyenera kumasula nati yaing'ono ya loko. Osadandaula za mtedza kugwa kumapeto kwa thupi la valve, chifukwa ulusi umagwedezeka kuti izi zisachitike.
Zikuwoneka kuti pali mawu akuti ma valve a Presta amatha kuthana ndi zovuta kwambiri-poganizira kuti ma valve a Schrader amatha kupirira mazana a psi (kupanikizika kwambiri kuposa momwe matayala anu amafunikira), izi sizingakhale zoona.
Komabe, valavu ya Presta ndiyodalirika kwambiri kuposa valve ya Schrader. Ndikosavuta kumenya valavu yamkati yamkati ndikuwerama kapena kuswa, chifukwa chake muyenera kusamala. Komabe, spool imasinthidwa mosavuta ndi zida zokhazikika.
Ma valve a Presta amatha kukhala ndi mphete yotsekera kuti ateteze thupi la valve kumphepete. Izi zitha kuwapangitsa kukhala kosavuta kufufuma. Chophimba cha fumbi sichiyenera kusindikizidwa, koma chimathandiza kuti valavu ikhale yoyera.
Mtundu umodzi wokha wa valve womwe mungakumane nawo ndi Dunlop (wotchedwanso Woods) valavu. M'mimba mwake pansi ndi ofanana ndi valavu ya Schrader, koma imatha kutenthedwa ndi zipangizo zofanana zapampu monga Presta valve.
Izi ndizodziwika kwambiri m'matauni / njinga zoyimirira ku Europe ndi madera ena padziko lapansi, koma simungathe kukumana ndi njinga zamtunduwu ku UK kapena ku US.
Valavu ya chipangizo chopanda chubu imalumikizidwa mwachindunji kumphepete, osati gawo la chubu.
Ngati muli ndi valve ya mtundu wa Schrader monga momwe tawonetsera pa chithunzi pamwambapa, ndiye chinthu choyamba chimene muyenera kuchita ndicho kuchotsa kapu ya fumbi (ngati ilipo).
Phunzirani tayala kukhala mtengo pakati pa osachepera ndi pazipita otchulidwa pa matayala sidewall, ndiyeno chotsani mpope. Mwatha!
Ngati njinga yanu ili ndi valavu ya Presta, choyamba muyenera kuchotsa chivundikiro cha valve ya pulasitiki (ngati chaikidwa).
Tsopano gwirizanitsani mutu wa mpope womwe mwasankha ku valavu yotseguka ndikulowetsani tayalalo kuti likhale ndi mphamvu pakati pa zochepa ndi zowonjezereka zomwe zatchulidwa pamphepete mwa matayala.
Ngati mukugwiritsa ntchito chipangizo chopanda machubu, kapena chubu chokhala ndi chosindikizira mkati, ndikofunikira kuchitapo kanthu kuti mupewe kutsekeka kwa mpope.
Tembenuzirani gudumu kuti valavu ikhale pansi ndikuisiya kwa mphindi zingapo kuti sealant iliyonse ikhoza kukhetsa.
Tembenuzani gudumu kuti valavu ikhale pamwamba, ndiyeno mufufuze tayala. Izi ndizoonanso popukuta matayala kuti ntchofu zisapope paliponse.
Tinganene kuti ngati mungakhale ndi mtundu umodzi wa mpope, gulani mpope wokwawa wapakhomo chifukwa ndi wothandiza, wachangu komanso wosavuta kugwiritsa ntchito.
Komabe, n’zosakayikitsa kuti kugwiritsa ntchito pampu yaing’ono yaing’ono mukakhala pamsewu n’kothandiza kwambiri—kupanda kutero mukhoza kumamatira m’mphepete mwa msewu ngati mutakhomeredwa.
Tili kale ndi kalozera wokuthandizani kusankha pampu yabwino kwambiri yanjinga pazosowa zanu, koma apa pali malingaliro omwe mungaganizire.
Palibe malire a mapampu okwawa. Onse amagwira ntchito yofanana, ndipo ena amadzimva kuti ndi apamwamba kuposa ena.
Kuchokera pa Park Tool PFP8 yotsika mtengo kwambiri ya Silca Pista Plus, mutha kupeza chinthu chomwe chikugwirizana ndi zosowa zanu.
