Isembozo se-valve kanye ne-cylinder head sealant

i-valve cover sealant isebenza emazingeni okushisa aphezulu, kanye nokuthintana nowoyela. Ngakho-ke, ukukhethwa kwendlela eyodwa noma enye kufanele kusekelwe eqinisweni lokuthi i-sealant akufanele ilahlekelwe izakhiwo zayo zokusebenza ezimweni ezinzima.

Kunezinhlobo ezine eziyisisekelo zama-sealants - i-aerobic, ukuqina, ethambile futhi ekhethekile. Uhlobo lwakamuva lufaneleka kakhulu njenge-valve cover sealant. Ngokuqondene nombala, ezimweni eziningi lokhu kumane kuyisu lokumaketha, njengoba abakhiqizi abahlukene bemikhiqizo enezici ezifanayo bangase babe nemibala efanayo, kuyilapho behluka ekusebenzeni.

izidingo ze-sealant.

Lapho ukhetha ithuluzi elilodwa noma elinye, okokuqala, udinga ukunaka izici zayo zokusebenza. Njengoba kushiwo ngenhla, okokuqala, udinga ukukhetha i-sealant, ekwazi ukusebenza emazingeni okushisa aphezulu. Ngakho-ke, lapho izinga lokushisa liphakeme elikwazi ukumelana nalo, lingcono. Lesi yisimo esibaluleke kakhulu!

Isici sesibili esibalulekile ukumelana nama-chemical compounds ahlukahlukene anolaka (amafutha enjini namafutha okudlulisela, izinyibilikisi, uketshezi lwamabhuleki, i-antifreeze kanye nolunye uketshezi lwenqubo).

Isici sesithathu sithi ukumelana nokucindezeleka kwemishini nokudlidliza. Uma lesi sidingo singahlangatshezwana nayo, i-sealant izomane idilike ngokuhamba kwesikhathi futhi ichitheke endaweni lapho yayibekwe khona ekuqaleni.

Isici sesine yilesi lula ukusetshenziswa. Okokuqala, iphathelene nokupakisha. Kufanele kube lula kumnikazi wemoto ukusebenzisa umkhiqizo endaweni yokusebenza. Okusho ukuthi, kufanelekile ukuthenga amashubhu amancane noma izifutho. Inketho yokugcina ilula kakhulu, futhi ngokuvamile ibhekwa njengochwepheshe, njengoba isetshenziswa abasebenzi besiteshi sesevisi.

Ungakhohlwa ukuthi i-sealant inomkhawulo wokuphila.

Uma ungahle uhlele ukuyisebenzisa kwenye indawo ngaphandle kwesembozo se-valve, akufanele uthenge iphakheji yevolumu enkulu (ama-sealants amaningi aneshalofu yokuphila kwezinyanga ezingu-24, futhi izinga lokushisa lokugcina lika-+5 ° C kuya ku-+25 ° C, nakuba lolu lwazi ludinga ukucaciswa emiyalweni ethile yethuluzi).

Uma usebenzisa amathuluzi anjalo, udinga ukukhumbula mayelana nobuchwepheshe bomhlangano. Iqiniso liwukuthi abakhiqizi bezimoto abaningi babeka ama-agent anjalo okuvalwa kanye ne-gasket yekhava. Kodwa-ke, lapho uqaqa injini evuthayo yangaphakathi (isibonelo, ukulungiswa kabusha kwayo), umthandi wemoto noma izingcweti esiteshini sesevisi ngeke baphinde bafake isivalo, okuzoholela ekuvuzeni kukawoyela. Esinye isizathu okungenzeka salokhu ukungqubuzana kwetorque eqinisayo yamabhawodi afakwayo.

Uhlolojikelele lwama-sealants adumile

Ukubuyekezwa kwama-valve cover sealants kuzosiza abanikazi bezimoto ukuthi banqume ngokukhetha uhlobo oluthile, ngoba okwamanje kunemikhiqizo eminingi enjalo ezitolo nasezimakethe zezimoto. Futhi ukubuyekezwa kuphela ngemva kokusetshenziswa kwangempela kungaphendula ngokugcwele ukuthi iyiphi i-sealant engcono. Ukunakekela ngokweqile lapho ukhetha kuzosiza ukuzivikela ekuthengeni izimpahla zomgunyathi.

Ukumelana Nokushisa Okumnyama KwenziweDeal

Ama-nuances okusebenzisa i-sealant yezembozo ze-valve

noma yimaphi ama-sealants asohlwini anezici zawo. Ngakho-ke, uzothola ulwazi olunembile ngokusetshenziswa kwabo kuphela emiyalweni enamathiselwe ethuluzini. Nokho, ezimweni eziningi kunenani lemithetho evamile kanye namathiphu nje awusizo okufanele alandelwe. okungukuthi:

Uhlolojikelele lwe-Popular Machine High Temperature Sealants

• I-sealant iba vulcanized ngokuphelele ngemva kwamahora ambalwa kuphela.. Uzothola ulwazi oluqondile emiyalweni noma emaphaketheni. Ngakho-ke, ngemva kokuyisebenzisa, imoto ayikwazi ukusetshenziswa, futhi ngisho nokuqala injini yomlilo yangaphakathi ngokungenzi lutho kuze kube yilapho ukwakheka komile ngokuphelele. Uma kungenjalo, i-sealant ngeke yenze imisebenzi eyabelwe yona.
• Indawo yokusebenza ngaphambi kokufaka isicelo akudingekile kuphela ukwehlisa, kodwa futhi ukuhlanza kusuka ekungcoleni nakwezinye izakhi ezincane. Izinyibilikisi ezihlukahlukene (hhayi umoya omhlophe) zingasetshenziselwa ukwehlisa amafutha. Futhi kungcono ukuyihlanza ngebhulashi lensimbi noma i-sandpaper (kuye ngokuthi izinga lokungcola kanye nezakhi ezizohlanzwa). Into esemqoka ukuthi ungayidluli.
• Ukuze kuhlanganiswe kabusha, amabhawodi kuhle ukuqinisa nge-torque wrench, ubheka ukulandelana okuthilekuhlinzekwe ngumkhiqizi. Ngaphezu kwalokho, le nqubo yenziwa ngezigaba ezimbili - ukuqiniswa kokuqala, bese kuba okuphelele.
• Inani le-sealant kufanele libe phakathi. Uma kuningi, khona-ke lapho iqinisiwe, ingangena enjini yangaphakathi yomlilo, uma incane, khona-ke ukusebenza kahle kokusetshenziswa kwayo kunciphisa ku-zero. futhi ungambozi yonke indawo ye-gasket isilonda!
• I-Sealant kufanele ibekwe emgodini wekhava bese ulinda cishe imizuzu eyi-10, futhi ngemva kwalokho ungakwazi ukufaka i-gasket. Le nqubo inikeza ukunethezeka okukhulu nokusebenza ngempumelelo kokuvikela.
• Uma usebenzisa i-gasket engeyona eyangempela, ngakho-ke kuhle kakhulu ukusebenzisa i-sealant (nakuba kungenjalo), njengoba ubukhulu bayo bejiyomethri nokuma kungase kuhluke. Futhi ngisho nokuphambuka okuncane kuzoholela ekucindezelekeni kwesistimu.

Zenzele ezakho iziphetho..

Kukunoma yimuphi umshayeli ukukhetha ukuthi uzoyisebenzisa noma cha. Nokho uma usebenzisa i-gasket engeyona eyangempela, noma ukuvuza kuvele ngaphansi kwayo - ungasebenzisa i-sealant.
