A cikin 'yan shekarun nan, kiyaye kuzari da raguwar gurɓataccen iska sun zama yanayin lokutan, kuma ƙananan motoci ma shine yanayin gabaɗaya. A ƙarƙashin waɗannan manyan tushe guda biyu, yin amfani da kayan gami na aluminium a cikin motoci ya yi yawa, kuma ana samun ƙarin sassan motoci ta mutu-simintin. A matsayin abubuwan da aka ƙera na motoci, yawancin tubalan injin silinda an yi su ne da aluminium da baƙin ƙarfe. Daga cikin su, tubalan aluminium da aka yi da ƙarfe sun sami ƙarin yabo. Kamfanonin kera motoci na Japan, Koriya, Turai da Amurka galibi suna amfani da tubalan aluminium na ƙarfe.

A fagen samar da shinge na silinda, yashi na siminti na baƙin ƙarfe yana da fa'ida na tsari mai sauƙi, farashi mai sauƙi, rigidity mai kyau da juriya mai zafi, amma kuma akwai gazawa, wato, nauyi ya yi yawa.

 Idan kuka raba ƙwanƙwasa ƙasa da ƙasan silinda da layin silinda sama da shingen silinda a cikin biyu, yi amfani da allurar aluminium a ƙasa kuma ku jefa baƙin ƙarfe a saman, zaku iya yin abubuwa biyu da dutse ɗaya, wanda ba kawai yana rage ingancin shingen silinda ba. , amma kuma yana kula da fa'idar katangar simintin ƙarfe.

 Silinda na ƙasa yana nufin ƙananan ɓangaren murfin injin bayan irin wannan rarrabuwa zuwa biyu. Saboda jikin silinda na ƙasa sashi ne mai kauri mai kauri, kuma kaurin bangon ya bambanta ƙwarai, yana da wahalar yin gyare-gyare. Mun koya daga ƙwarewar cikin gida da ta waje da ta dace, wanda aka ƙera da haɓaka saitin fasahar jujjuyawar ƙananan silinda don injin 1.5T, kuma gwajin ya yi nasara sosai.

1. Difficulties a mutu simintin na aluminum gami m silinda block

Aluminum gami ƙananan silinda simintin taro shine 8.4kg, girman shaci shine 382mm × 258mm × 67mm, nauyin siminti na mutu shine 11.1kg, kayan shine A380, kuma matsakaicin kaurin bango shine 7.2mm. Tunda an haɗa katangar silinda ta ƙasa da ƙwanƙolin ruwa, ana buƙatar saka baƙin ƙarfe.

Tsarin mutuƙar simintin simintin gyare-gyare na ƙananan silinda yana da rikitarwa, kuma manyan matsalolin sune kamar haka:

• Na farko, ana buƙatar sanya simintin gyare -gyare a cikin guda 5 na abubuwan da aka saka na baƙin ƙarfe, kuma abubuwan da aka saka na baƙin ƙarfe dole ne a saka su daidai a kan siminti na aluminium ba tare da rabuwa ba.
• Na biyu, kaurin ƙananan simintin gyaran jiki yana da kauri kamar 2mm a sashin mafi ƙanƙanta da 24mm a ɓangaren mafi kauri, kuma rarrabawar ba ta daidaita sosai.
• Na uku, saboda babban banbanci a kauri tsakanin bangon bango biyu na sakawa, yana kawo babban wahala ga cikawar kwararar ruwan gami na aluminium, kuma yana gwada ikon ciyarwa.
• Na huɗu, simintin ƙarfe na aluminium yana da sauƙin lahani kamar ramuka, ramuka masu raguwa, fasa, da raguwar porosity, kuma sarrafa inganci yana da wahala.

2. Key maki na mutu simintin fasaha na aluminum gami m Silinda block

Dangane da gwajin gwajin, mun yi imani cewa manyan mahimman abubuwan fasaha na samar da mutuƙar simintin ƙasan silinda sune kamar haka:

• Na farko, a kimiyance ya tsara tsarin ƙulli na simintin toshe mutu simintin. Matsayin sakawa a tsakiyar katangar silinda yana da bango mai kauri, kuma babba da ƙananan sassa masu kauri ne da manyan sassa. Sabili da haka, muna zaɓar zubin gefe ɗaya, don a iya ciyar da narkakken aluminium daga ƙasa. , Tafasa ta tsakiyar sakawa sannan ta kai saman.
• Na biyu, muna amfani da sifar haƙora mai kamannin haƙora mai ɓarna ɓarna. Haɗuwa da katanga mai cike da haƙora mai sanyaya haƙora da injin injin zai iya inganta matsalar rashin isasshen ruwan da ganuwar gefen bakin ciki ke haifarwa da tabbatar da ingancin simintin gyare-gyare.
• Na uku, don inganta ɗimbin ruwan allurar aluminium da shigar baƙin ƙarfe, muna sanya abubuwan da ake sakawa, waɗanda ba kawai ke tabbatar da cewa baƙin ƙarfe da baƙin ƙarfe ba su rarrabu bayan kafawa, amma kuma yana inganta ingantaccen ruwa mai narkar da aluminium. . Bayan gwaji, tsarin ciki na ƙananan silinda jikin da muka samu yana da yawa kuma bayyanar tana da kyau.

A cikin aiwatar da mutuwar simintin ƙananan silinda, sigogi na kimiya da ƙima sune garantin samun babban silinda mai inganci. Mun yi imanin cewa sigogin aiwatarwa masu zuwa sune mahimman abubuwan da ke haifar da gyare -gyare:

• Da farko, mutu simintin zafin jiki.Da tsarin mutuƙar simintin, ya kamata a sarrafa zafin jiki na narkakken aluminium, saboda yawan zafin jiki ya yi yawa ko ya yi ƙasa sosai don cimma sakamako mai kyau na simintin gyare-gyare, maɗaukaki zai sauƙaƙa haifar da raguwa da raguwa, da yayi ƙasa sosai zai iya haifar da ƙarancin cikawa. Gabaɗaya magana, daidaitaccen zafin jiki na narkakken aluminium yakamata ya kasance tsakanin 650-665 ℃, kuma zafin jiki bayan feshin ƙirar yakamata ya kasance tsakanin 150-200 ℃.
• Na biyu, yawan zafin jiki na sakawa. Lokacin da abin da aka saka ya kai 120-140 ℃, narkakken aluminium ya mamaye gefe ɗaya na tankin, wanda zai iya inganta ingancin ciki.
• Na uku, mutu mutu da sauri da jinkirin allurar allura da matsin lamba.Ya kamata a sarrafa saurin allurar sauri da jinkirin allura a kusan 4m/s da 0.22m/s bi da bi, kuma yakamata a sarrafa matsa lamba a kusan 70MPa.
• Na huɗu, ingancin zubin aluminium.A matsayin ainihin kayan simintin gyare -gyaren, ingancin narkakken aluminium yana ƙayyade ingancin simintin gyare -gyare. Don haka, don tabbatar da ingancin narkar da aluminium, kowane fakiti na narkakken aluminium dole ne a tsaftace shi kuma a gurɓata don gujewa gurɓatawa.

3. Lahani a mutu simintin aluminum gami ƙananan silinda da matakan kariya

Bayan da aka ƙera simintin, mun yi binciken X-ray akan simintin gyare-gyare kuma mun gano cewa simintin yana da wasu lahani na ciki, kamar ramukan ramuka, ramuka, da ƙanƙantar da porosity.

 Don haɓaka lahani da haɓaka inganci, mun ba da shawarar matakan daidaitawa, manyan jagororin su sune kamar haka:

• Na farko, inganta tsarin tankin da ya cika. Ramin da ke kwarara yana da ayyukan fitar da iskar gas a cikin rami, adana gas mai gauraye, da canja wurin raguwa/raguwa. Bayan gwaje -gwaje da bincike akai -akai, mun gano cewa zamu iya amfani da hanyoyi kamar faɗaɗawa da ƙara ramuka masu yawa don inganta raguwa, ramuka da sauran lahani. Tunda akwai ƙarin raguwa da porosity a tsakiyar simintin gyare -gyare, matsi na cikawa zai shafi idan an saita tashar jirgin ruwa a kan babban jirgi, don haka galibi ana zaɓar tashar ruwa mai kwarara.
• Na biyu, inganta tsarin sanyaya injin. Ramin raguwa a cikin simintin gyare -gyare gabaɗaya yana bayyana a wuraren da zafin jiki na gida yayi yawa ko kaurin bangon yayi yawa. Ta hanyar bincike, mun gano cewa mafi girman zafin jiki a bangon gefen kauri na iya haifar da ramukan ƙanƙara. Tun da ƙaramin diamita na bututu mai sanyaya tabo da farko an zaɓa shine 12mm, wanda ba zai iya sanyaya wuraren da aka ambata a sama yadda yakamata ba, mun inganta tsarin bututu na ruwa mai sanyaya, ta amfani da kayan aikin sanyaya matsin lamba da bututu mai sanyaya bakin karfe. diamita na ciki na 4mm. Mun sanyaya kwandon kwandon a ɓangarorin biyu na simintin zuwa kusan 180 ° C, wanda ya rage yanayin ƙuntatawa sosai kuma ya inganta ingancin simintin.
• Na uku, inganta rabuwa da sakawa. Dangane da abin da ke rarrabewa tsakanin abubuwan sakawa da simintin gyaran ƙarfe na aluminium, mun ɗauki matakan da ke gaba: na farko, yi amfani da sirara don tsabtace abin da aka saka don inganta danshi; na biyu, yi duba rami na sakawa da duba bayyanar a kan abin da aka saka, ta amfani da waya karfe An cire wani ɓangare na tsattsagewar tsatsa. na uku, an yi gwajin preheating akan abubuwan da aka saka. Binciken ya gano cewa lokacin da zazzabi ya kai 120 ℃ ko sama da haka, ana iya magance matsalar rabuwa da sakawa yadda yakamata.

4. Kammalawa

 A cikin 'yan shekarun nan, tare da ci gaba da manufofin rage kuzarin makamashi na ƙasata da ƙaƙƙarfan ƙazamar ƙa'idar mota, ana amfani da kayan gami na aluminium da yawa a cikin motoci, kuma ana samun ƙarin sassan mota ta mutu-simintin, ciki har da Babban abubuwan da ke cikin motoci - injin. A halin yanzu, yin amfani da simintin ƙarfe na aluminium ya zama juzu'i, wanda zai iya rage nauyin silinda kuma samun ingantaccen silinda. Koyaya, saboda hadaddun tsarin jikin silinda na ƙasa da babban banbanci a cikin kaurin bango, mutuƙar siminti na ƙasan silinda na aluminium ya fi wahala.

Ta hanyar binciken gwaji, wannan takarda tana nazarin matsaloli a cikin fasahar simintin mutuƙar aluminium na ƙananan silinda, kuma tana ba da shawarar tsarin ƙirar silinda ta mutu a kimiyyance, ta amfani da ƙirar haƙora mai ƙyalƙyali mai ƙyalƙyali mai ƙyalƙyali mai ƙyalƙyali mai ƙyalƙyali mai ƙyalƙyali da ƙyallen fasaha don preheat abubuwan da aka saka da sauran alumomin aluminium. Key maki na mutu-simintin fasaha na ƙananan Silinda block. Bugu da ƙari, yana kuma taƙaita lalatattun abubuwan da ke haifar da raunin allurar ƙaramin silinda na aluminium, kamar ramukan ƙanƙara, pores, ƙanƙarar porosity da sauransu, kuma yana ba da shawarar matakan da suka dace, waɗanda ke ba da bayanin ka'ida don mutuƙar simintin injin injin mota na aluminium ƙasan ƙarami. silinda.
