A cikin aiwatar da ƙira ko tantance gaskets kumfa, zaɓin kayan yawanci yana ɗaukar matakin tsakiya. Duk da haka, kaurin kumfa yana da mahimmanci daidai. Wannan saboda kaurin gasket ɗin kumfa yana yin tasiri kai tsaye akan aikin matsawa, halayen karkatar da shi, tasirin rufewa, da dogaro na dogon lokaci. Don haka, ta yaya daidai kumfa kauri siffar gasket yi? Kuma waɗanne mahimman abubuwa ne ya kamata injiniyoyi su tantance lokacin da suke tantance kauri da ya dace don takamaiman aikace-aikacen su?
Kafin bincika takamaiman tasirin kauri, yana da mahimmanci a fara fahimtar ainihin manufar aikin kumfa gasket. A mafi mahimmanci matakinsa, gasket dole ne ya cika mahimman ayyuka masu zuwa:
●Kafa hatimin abin dogaro don kiyaye kura, damshi, iska, ko ruwaye
●Isar da matsawa mai sarrafawa lokacin da ake ɗauka
● Daidaita ga rashin daidaituwa da rashin daidaituwa na girma
●Yin tsayayya da al'amurra kamar masu rarrafe, saitin matsawa, da lalacewa ta hanyar abubuwan muhalli
Ana yawan yin gaskets kumfa daga rufaffiyar tantanin halitta ko buɗaɗɗen tantanin halitta. Misalai sun haɗa da polyethylene (PE), polyethylene mai haɗin giciye (XLPE), polyurethane (PU), EPDM, neoprene, da vinyl nitrile (VN) — don suna kawai. Kowane ɗayan waɗannan kayan yana ƙunshe da kaddarorin inji da sinadarai na musamman. Duk da haka, ba tare da la'akari da nau'in kumfa da aka yi amfani da shi ba, kauri ya kasance ma'anar ma'anar abin da ke tsara aikin gasket gaba ɗaya.
Kaurin kumfa yana taka muhimmiyar rawa wajen tantance nawa gasket zai iya dannewa kafin ko dai ya buga ma'anarsa ta 'ƙasa' ko kuma rasa kayan sa na roba na dogon lokaci. Daga madaidaicin matsayi, gasket yakamata yayi aiki a cikin kewayon matsawa na 25% zuwa 50% dangane da kauri na farko. Idan matsawa ya wuce 60%, zai iya haifar da kayan ya lalace kuma ya haifar da saitin matsawa - al'amari inda kumfa ya kasa yin billa gaba ɗaya da zarar an cire nauyin da aka yi amfani da shi.
Ƙananan zanen kumfa sau da yawa suna kaiwa ga matsewar matsuguninsu da sauri da sauri kuma suna iya yin ƙasa idan aka yi musu matsakaicin nauyi. Sabanin haka, kumfa mai kauri yana ba da mafi kyawun yanki mai karimci, yana ba da damar jujjuyawa mafi girma kafin a kai iyakar matsi.
Kaurin kumfa kuma yana tasiri yadda ake rarraba ƙarfi da ƙarfi da kuma yadda yadda gasket ɗin zai iya daidaitawa ga rashin daidaituwa akan abubuwan da suka dace. Lokacin yin hatimi a kan m, mara daidaituwa, ko maras lebur, gaskets masu kauri sun fi dacewa don cike giɓi da tabbatar da matsa lamba a duk yankin lamba.
Don kwatanta:
●A 1/16-inch gasket yawanci isar da isasshen sealing yi tsakanin biyu machined karfe saman, inda lamba jirgin ya kasance uniform.
●A 1/4-inch gasket, duk da haka, na iya zama dole don amfani da simintin gyaran kafa ko textured gidaje, inda surface flatness bambanta fiye da muhimmanci.
●Rage ƙunci na farko (wannan dukiya kuma ta dogara ne akan yawan kumfa da ma'auni na asali)
●Ingantacciyar ƙarfin ɗaukar makamashi gaba ɗaya
●Mafi girman kewayon ƙaura kafin fara nakasar dindindin
CFD daidaitaccen ma'auni ne wanda ke nuna adadin ƙarfin da ake buƙata don matsa kumfa zuwa takamaiman kashi, yawanci 25%. Yayin da kauri na gasket ke ƙaruwa, CFD yana ƙoƙarin raguwa-ma'ana kumfa yana buƙatar ƙarancin ƙarfi don damfara. Wannan na iya zama da fa'ida a cikin majalisai marasa nauyi ko gidajen robobi inda masu ɗaure ba za su iya yin amfani da karfin juyi ba.
Wannan ya ce, idan kumfa yana da sauƙin matsawa, matsa lamba a wurin dubawa na iya saukewa, musamman lokacin da aka fallasa ga girgiza ko canje-canjen zafin jiki. Don ingantaccen aiki na dogon lokaci, dole ne a daidaita kauri tare da madaidaicin yawa da ƙarfi.
Gasket ɗin kumfa masu kauri sun fi saurin ratsawa, ko nakasar sannu a hankali ƙarƙashin kaya akai-akai, musamman ma a cikin yanayi mai zafi. Don rage wannan haɗarin, injiniyoyi yakamata su zaɓi kayan da ƙananan saiti masu ƙima. Wannan yana da mahimmanci musamman a cikin buƙatar aikace-aikacen kamar:
● Ƙarƙashin ƙaƙƙarfan kayan aikin mota
●HVAC hanyoyin shiga
● Wuraren lantarki na waje
TOPSUN Foam yana ba da kayan da aka ƙera don saduwa da ƙayyadaddun ƙa'idodin aiki - gami da UL 50 / UL 50E, UL 94, FMVSS 302, da ASTM D1056 - suna taimakawa tabbatar da hatimi mai dorewa a cikin kewayon kumfa mai yawa.
●Mating saman ba daidai ba ne, karkatacce, ko sassauƙa
●Dole ne a cike manyan gibi ko juriya
● Ana kuma buƙatar keɓewar girgiza ko ɗaukar tasiri
●Gaske dole ne ya yi lissafin haɓakar thermal ko motsi
● Ƙarƙashin ƙarfin matsawa kawai yana samuwa (misali, majalissar filastik-zuwa-roba)
● Filayen mating suna lebur, santsi, kuma daidai
● Ana buƙatar matsa lamba mafi girma da riƙewar ƙarfi
●Space yana iyakance a cikin ambulaf ɗin ƙira
●Maɗaukakin zafi ko lantarki dole ne ya kasance daidai
● Ana samun ƙarfin matsawa (misali, shingen ƙarfe-zuwa ƙarfe)
Kaurin kumfa ɗaya ce kawai na ƙirar gasket. Zabi kuma yakamata ya lissafta:
● Akwai ƙarfin matsawa yayin taro
● Haƙuri tari a tsakanin sassan
●Bambance-bambance a cikin tazarar hatimi
● Bayyanar muhalli (zazzabi, zafi, UV, sunadarai)
● Saitin matsawa na dogon lokaci da aikin sake dawowa
Halin kumfa ba na layi ba - ninka kauri ba yana nufin iya matsawa ninki biyu ba. Don sakamako mafi kyau, kauri, yawa, da tsari ya kamata a daidaita su tare da taimakon ƙwararren kayan aiki.
Kaurin kumfa yana da mahimmanci ga amincin gasket, musamman a aikace-aikacen da ke buƙatar ɗaukar dogon lokaci, sarrafa rawar jiki, ko shan kuzari. Gasket ɗin da ya yi ƙanƙara yana iya lalata hatimin, yayin da wanda ya yi kauri zai iya datsewa ba daidai ba ko kuma ya lalace cikin lokaci.
A TOPSUN Foam, muna taimaka wa injiniyoyi, OEMs, da masu zanen kaya masu kyau-tunani na gasket a kusa da ainihin ƙarfi, muhalli, da yanayin amfani. Daga babban adadin madaidaicin yanke-yanke zuwa samfuran al'ada a cikin kauri na musamman, muna ba da mafita na kumfa da aka ƙera don aiki mai ɗorewa.
