Lokhu kungase kube into eyisisekelo, kodwa ukukwazi ukupompa amathayi ebhayisikili kuyikhono eliyisisekelo lanoma yimuphi umgibeli wamabhayisikili.
Abaningi benu sebeyazi kakade indlela yokwenza lokhu, kodwa kulabo abangazi, izinhlobo ezahlukene zama-valve, amaphampu, futhi okubaluleke nakakhulu, ingcindezi yokufaka umoya amathayi ingaba nzima kakhulu. Ake sikuqondise ohlelweni.
Ukupompa amathayi kuwumsebenzi osheshayo futhi kungathuthukisa kalula injabulo yakho yokugibela. Ukugijima isondo elingalungile kungaba nomthelela ongemuhle endleleni ibhayisikili lakho eligibela ngayo futhi kungase kwenze ibhayisikili lakho libe lula kakhulu ekubhobhozweni.
Uma ungakaze ulungise indawo yokubhoboza ngaphambili, kungenzeka ukuthi awuzange ucabange ukuthi ungawugcina kanjani umoya ngaphakathi kwesondo.
Amabhayisikili amaningi azosebenzisa amashubhu angaphakathi. Leli ishubhu elingangeni moya elisesimweni se-donut, elingaphakathi ethayini, eline-valve yokulimpompa, ongayibona ngaphandle.
Lapho isondo liphefumulelwe yi-tube, lizobambelela phansi futhi linikeze ukuvikeleka kokubhoboza.
Kungenzeka ukuthi uke wezwa ngamathayi angenashubhu, alahla amashubhu angaphakathi asebenzise amarimu akhethekile namathayi ukuze avale umoya ngaphandle kwamashubhu angaphakathi. Lezi ngokuvamile zidinga i-internal tubeless sealant, lolu ketshezi luzovimba noma iyiphi indawo lapho umoya uphuma khona.
Amathayi angenayo i-tubeless avame kakhulu emabhayisikili asezintabeni, kodwa ubuchwepheshe buthuthela emabhayisikili omgwaqo.
I-Tubeless sealant nayo ingavimba ukubhobozwa, futhi ukungabikho kweshubhu elingaphakathi kusho ukuthi ubungozi bokwenza isicaba buphansi kakhulu-okungukuthi, lapho ishubhu yakho yangaphakathi icindezelwa unqenqema, izodala ukubhobozwa. Ngakho-ke, amathayi angenawo ama-tubeless angagijima ngezingcindezi eziphansi kunamathayi we-tube ukuze athuthukise ukunethezeka, isivinini kanye nokudonsa.
Ekupheleni okuphezulu kakhulu, ungathola futhi amathayi we-tubular. Leli isondo elineshubhu elingaphakathi, kodwa awavamile ukubonakala noma asetshenziswe ngaphandle kwemincintiswano yobungcweti.
Amathayi agijimayo lapho kunezingcindezi eziphakeme kakhulu noma eziphansi kakhulu kungaba yingozi futhi kuthinte kabi ukuphathwa kwebhayisikili.
Sizoxoxa ngokuthi iyiphi ingcindezi efanele kamuva, kodwa manje ake sibheke izinkinga ezingase zibe khona.
Uma ugijima amathayi ngomfutho ophansi kakhulu, amathayi angase aguge ngaphambi kwesikhathi. Ukugoba ngokweqile kodonga oluseceleni kungabangela ukuqhekeka kwegobolondo lamasondo kanye nesondo libe brittle. Lokhu kungase kugcine kuholele ekuqhumeni.
Ukucindezela okuphansi kakhulu nakho kuzokwandisa ukuzwela kwakho kuma-puncture, futhi kungase kubangele ngisho namathayi akho ukuthi ahlehle unqenqema lapho ujika ngesivinini esikhulu (ukucindezela kwangaphakathi kuyisizathu sokulungisa isondo kurimu).
Uma isondo lichezukile lize liyofika emgqeni, lizodala nomonakalo. Lokhu kungabangela ukubola noma ukuqhekeka, okungalimaza amasondo akho futhi kubangele ukushintshwa okumba eqolo.
Ngakolunye uhlangothi, ukucindezela okwedlulele kungase kubangele ukuba amathayi akho aqhume aphume rimu, okungaba nemiphumela yokuqhuma. Lokhu kucindezela kuzophinde kumpintshe isondo, ngoba uma i-pressure iphezulu kakhulu, umfutho wesondo ungaba phezulu kakhulu.
Mayelana nokuphatha, ukucindezela okuphansi kuzobangela ukuthi amathayi agibele ngaphansi komthwalo, ngaleyo ndlela kuthinte ukuphatha. Ibhayisikili lakho lizozizwa lingalawuleki, lihamba kancane futhi livilapha.
Ngakolunye uhlangothi, ukucindezela okuphezulu kakhulu kuzoholela ekunciphiseni ukubamba nokugibela okungagculisi, okuholela ekukhathaleni, okubuye kuthinte ukuphatha.
Zimbili izimbangela zokuphantshisa kwesondo. Kungenzeka ukuthi ubhobokile, noma isondo lakho lisanda kuphephuka ngokuhamba kwesikhathi.
Amapheshana angenaglue alungele ukulungiswa ngokushesha, futhi uma unesikhathi esiningi, ikhithi yendabuko iyindlela eguquguqukayo.
Wonke amasistimu amathayi azovuza umoya kancane ngoba ishubhu elingaphakathi alivalwanga ngokuphelele. Isibonelo, uma kuqhathaniswa neshubhu le-latex elilula, ishubhu yerabha ye-butyl evamile ingabamba umoya kahle, kanti leli lakamuva livuza ngokushesha. Ngisho nomshini ongenamashubhu uzovuza umoya kancane.
Amapayipi amadala azovuza umoya omningi kunamapayipi amasha, ngakho-ke uma amapayipi akho engakashintshwa isikhathi eside, angase afaneleke ukubukeka. Akwenzeki, kodwa futhi kungenzeka (ikakhulukazi emapayipini amadala) ukuthi i-valve ingasavali kahle.
Indlela engcono kakhulu yokuhlola ukuthi kwenzekani ukuzama ukumpompa amathayi. Uma igcina umoya, ungase ungadingi ukwenza okwengeziwe. Uma kungenjalo, khona-ke ungase ube ne-puncture.
Uma ivuza kancane ngobusuku obubodwa, kungenzeka ukuthi ijubane lakho lokubhoboza lihamba kancane, noma ishubhu elidala elidinga ukushintshwa.
I-valve iyisici esibalulekile sokugcina umoya ethayini, futhi ikuvumela ukuthi uvuthele (noma unciphise) isondo.
Ama-valve e-Schrader avame kakhulu kumabhayisikili aphansi kanye namabhayisikili asezintabeni esikhathi esidlule. I-valve efanayo ibuye isetshenziswe emathayini emoto.
Ukuhlanganiswa kwe-valve iyishubhu elingenalutho eline-valve yasentwasahlobo engakwazi ukuvaleka ngokuzenzakalelayo futhi ifakwe emzimbeni we-valve wangaphandle. Iphinikhodi inyukela phezulu isuka kuvalvu, ivamise ukugudluza ekugcineni kweshubhu elingaphandle. Le phinikhodi ingacindezelwa ukukhipha umoya.
Isembozo sothuli ku-valve ye-Schrader siyingxenye ebalulekile yomklamo. Uma i-valve ingavalwanga ngokuphelele, ingasiza ukuvala ngokuphelele i-valve. Ihlinzeka ngokuyisisekelo uphawu lwesibili "lwesipele".
Idizayini yasentwasahlobo ye-valve ngandlela-thile isengozini yokungcoliswa uthuli noma i-grit, ngakho-ke kubalulekile ukuyivikela.
Asuka emabhayisikili omgwaqo, lapho amavalvu emincane (6mm vs. 8mm ye-Schrader) asho ukuthi kunezimbobo zamavalvu ezincane kumasondo omgwaqo amancane (imvamisa ingxenye ebuthaka kakhulu yerimu).
Namuhla, zingabonakala emabhayisikili ezintaba kanye emabhayisikili emgwaqeni. Esikhundleni sokusebenzisa isiphethu, i-valve ilungiswa nge-nati ukugcina i-valve ivaliwe, nakuba i-valve ngokwayo "izovala ngokuzenzakalelayo" lapho ingcindezi ngaphakathi kwesondo ivala.
Kumavalvu e-Schrader, udinga kuphela ukucindezela iphinikhodi ukuze ukhulule umoya, kodwa kumavalvu e-Presta, kufanele uqale ukhulule inadi yokukhiya encane. Ungakhathazeki ngokuthi inati eliwa ekugcineni kwe-valve yomzimba, ngoba intambo iyashaywa ukuze lokhu kungenzeki.
Kubonakala sengathi kunesisho sokuthi ama-valve e-Presta angakwazi ukusingatha izingcindezi eziphakeme kangcono-kucabangela ukuthi ama-valve e-Schrader angakwazi ukumelana namakhulu ama-psi (ukucindezela okukhulu kunesidingo sakho samathayi), lokhu kungase kungabi yiqiniso.
Kodwa-ke, i-valve ye-Presta icwengwe kakhulu kune-valve ye-Schrader. Kulula kakhulu ukushaya umzimba we-valve wangaphakathi onentambo bese uwugoba noma uwuphule, ngakho-ke udinga ukuqaphela. Kodwa-ke, i-spool ishintshwa kalula ngamathuluzi ajwayelekile.
Ama-valve e-Presta angase abe nendandatho yokukhiya ukuze avikele umzimba we-valve onqenqemeni. Lokhu kungenza kube lula ukuwafutha. Isivalo sothuli akudingekile ukusivala, kodwa kusiza ukugcina i-valve ihlanzekile.
Okuwukuphela kolunye uhlobo lwevalvu ongahlangana nalo i-valve ye-Dunlop (ebuye yaziwe ngokuthi i-Woods). Ububanzi bayo obuphansi bufana ne-valve ye-Schrader, kodwa ingagcwaliswa ngezesekeli zepompo ezifanayo njenge-valve ye-Presta.
Lawa adume kakhulu emadolobheni/emabhayisikili asukumayo e-Europe nakwezinye izingxenye zomhlaba, kodwa mancane amathuba okuba uhlangane nalolu hlobo lwebhayisikili e-UK noma e-US.
I-valve ye-tubeless device ixhunywe ngokuqondile ku-rim, kunengxenye ye-tube.
Uma une-valve yohlobo lwe-Schrader njengoba kuboniswe esithombeni esingenhla, khona-ke into yokuqala okudingeka uyenze ukukhipha isivalo sothuli (uma sikhona).
Gcoba isondo libe yinani eliphakathi kwenani eliphansi neliphezulu elicaciswe onqenqemeni lwesondo, bese ususa iphampu. Uqedile!
Uma ibhayisikili lakho linevalvu ye-Presta enjalo, kufanele uqale ususe ikhava yevalvu yepulasitiki (uma ifakiwe).
Manje xhuma ikhanda lepompo olikhethayo ku-valve evulekile bese uvuthela ithayi ekucindezelweni phakathi kobuncane nobukhulu obucaciswe odongeni oluseceleni lwesondo.
Uma usebenzisa i-tubeless device, noma idivayisi ye-tube ene-sealant ngaphakathi, kufanelekile ukuthatha izinyathelo ezengeziwe ukuze ugweme ukuvaleka kwepompo.
Vula isondo ukuze i-valve ibe ngezansi futhi uyishiye imizuzu embalwa ukuze noma iyiphi i-sealant ikwazi ukukhipha.
Vula isondo ukuze i-valve ibe phezulu, bese ufutha isondo. Lokhu kuyiqiniso futhi lapho kuncishiswa amathayi ukuvimbela amafinyila ukuthi angafuthwa yonke indawo.
Singasho ukuthi uma ungaba nohlobo olulodwa lwepompo, thenga iphampu yesiseshi yasekhaya ngoba iyasebenza, iyashesha futhi kulula ukuyisebenzisa.
Nokho, akungabazeki ukuthi ukusebenzisa iphampu encane eyengeziwe uma usendleleni kuwusizo kakhulu-kungenjalo ungase ubhajwe eceleni komgwaqo uma ubhobozwa.
Sesivele sinomhlahlandlela wokukusiza ukuthi ukhethe iphampu yebhayisikili engcono kakhulu ngezidingo zakho, kodwa nazi ezinye iziphakamiso ongazicabangela.
Ayikho imikhawulo yamaphampu esiseshi. Ngokuyisisekelo bonke benza umsebenzi ofanayo, futhi abanye bazizwa bethuthuke kakhulu kunabanye.
Kusukela ku-Park Tool PFP8 ethengekayo kuya e-Silca Pista Plus ebiza kakhulu, ungathola njalo umkhiqizo ovumelana nezidingo zakho.
