Tushen Zaɓin Kayananan Yashi

Yashi shine mafi yawan abin da ake amfani da shi a cikin wannan tsari, don haka sunan yashi. A cikin shekaru 50 na ƙarshe, an daidaita ƙarin kayan aiki don aiwatar da kayan tsaftacewa.

A yau, sharuɗɗan fashewar bama-bamai da tsaftar fashewar fashewar bama-bamai sun fi fayyace tsari daidai, tunda kayan fashewa na iya haɗawa da kowane adadin samfura, kamar sutsan kwal, garnet, beads ɗin gilashi, harsashi na goro, da masara.

Ana iya amfani da fashewar sinadari akan kusan kowane bangare na tarakta, idan aka ba da madaidaicin kayan watsa labarai, matsin iska, ƙara, da bututun fashewa.

Wadannan su ne wasu daga cikin abubuwan da suka dace yayin zabar abubuwan da ake bukata.

The Compressor
Na'urar damfara ta iska ita ce mafi mahimmancin bangaren aikin fashewar yashi. Yana ba da ƙarar iska da matsa lamba don matsar da kafofin watsa labarai masu ɓarna duk da cewa bututun bututun bututun bututun bututun bututun bututun bututun bututun bututun bututun bututun bututun bututun iska yana ba da ƙarar iska da matsa lamba don kawar da ma'auni, tsatsa, ko suturar tsofaffi daga saman abin da ake nufi.

Don fashewar majalisar ministoci, ƙafafu 3 zuwa 5 cubic a minti daya (cfm) na iya zama isasshe, in ji shi. Don manyan ayyuka, kewayon 25 zuwa 250 cfm na iya zama dole.

Lokacin zabar tukunyar fashewa ko majalisa, akwai nau'i biyu da za a zaɓa daga: ciyarwar tsotsa da abinci mai matsa lamba.

Tsarin Ciyarwa
Tsarukan ciyar da tsotsa suna aiki ta hanyar yin amfani da abrasives kai tsaye cikin bindigar fashewar. Wannan ya dogara da iskar kwampreta da ake ciyar da ita cikin bindigar fashewar don haifar da gurɓataccen ruwa. Lokacin da aka kunna bindigar, ana tsotse abin da aka lalatar a cikin layin abinci zuwa bindigar fashewar. Iskar da ke tserewa daga nan tana ɗaukar abin da aka lalatar zuwa saman da aka yi niyya.

Sabanin haka, tsarin ciyar da matsa lamba yana adana abubuwan da aka lalata a cikin jirgi ko tukunya. Tukunyar tana aiki a matsa lamba daidai da na bututun kayan. Bawul ɗin sarrafawa wanda aka ajiye a ƙasan tukunyar ya misa shuɗi zuwa magudanar iska mai ƙarfi. Ruwan iskar daga nan yana ɗaukar abin da ke lalata ta cikin bututun fashewa zuwa saman aikin.

Bututun fashewar shine na'urar da ake amfani da ita don haɓaka saurin tasirin yashi mai fashewa. Duk da yake akwai nau'ikan nozzles iri-iri, akwai na kowa guda huɗu.

* Madaidaicin bututun ƙarfe yana haifar da tsayayyen tsari don tsaftace tabo ko fashewar hukuma. Yawancin lokaci ana amfani dashi don tsaftace ƙananan sassa.

* Bututun ƙarfe na venturi shine mafi kyawun zaɓi don haɓakar samarwa mai girma na manyan filaye. Yana da mahimmanci a lura, duk da haka, lokacin da fashewa a babban matsi (100 psi ko fiye), abrasives na iya kaiwa gudun sama da 500 mph.

* Ana iya ɗaukar bututun bututun mai-venturi a matsayin nozzles biyu waɗanda aka sanya ƙarshen zuwa ƙarshe. Ramin shigar da iska a jikin bututun ƙarfe yana ba da damar iskar kwampreso ta gauraya da iskar yanayi. Wannan aikin venturi yana ƙara cfm kuma yana ƙara girman ƙirar fashewar. Deardorff ya lura cewa bututun ƙarfe-venturi biyu shine mafi kyawun zaɓi don tsabtace ƙarancin matsa lamba. Wannan shi ne saboda aikin tsotsa na ramukan shigar da iska yana da ikon ɗaukar nauyin nauyi mai yawa, abrasives masu yawa ta hanyar bututun abu a ƙananan matsa lamba.

* Bututun mai fan yana samar da tsarin fan wanda ake amfani da shi don fashewa da manyan filaye masu lebur. Bututun fanko yana buƙatar ƙarin ƙarar iska na cfm don aiki.

Hakanan ana samun nozzles tare da zaɓi na kayan rufi, waɗanda suka haɗa da aluminum, tungsten carbide, silicon carbide, da boron carbide. A zahiri, zaɓin ya dogara ne akan kasafin kuɗin ku da kuma wahalar aikin. Kawai ku tuna cewa yawan amfani da kafofin watsa labarai yana ƙaruwa tare da lalacewa.

Duk Game da Abrasives
Abubuwan da ke shafar aikin abrasive sun haɗa da masu zuwa.

* Tauri na ƙura, lalata, ko abin rufe fuska don cirewa.

* Haɗin saman saman da hankali.

* Ana buƙatar ingancin tsaftacewa.

* Nau'in abrasive.

* Farashin farashi da zubarwa.

* Maimaita yuwuwar.

Abrasive wani bangare ne na kowane tsarin fashewa wanda a zahiri ke yin aikin tsaftacewa. Akwai manyan rarrabuwa guda huɗu don kayan abrasive.

* Abubuwan abrasives na halitta sun haɗa da yashi silica, yashi na ma'adinai, garnet, da hematite na musamman. Ana ɗaukar waɗannan abubuwan da za a iya kashewa kuma ana amfani da su musamman don fashewar fashewar waje.

* Abubuwan goge-goge na mutum ko ƙera, kamar beads na gilashi, aluminum oxide, silicon carbide, harbin ƙarfe, da kafofin watsa labarai na filastik, ana iya sake amfani da su kuma ana iya amfani da su a cikin tsarin da ke ba da damar farfadowa da sake yin amfani da su.

* Abubuwan da aka lalatar da su - irin su kwal slag, wanda shine samfuri na masana'antar sarrafa wutar lantarki - ana ɗaukar mafi yawan amfani da abrasive bayan yashi silica.

* Abubuwan abrasives marasa ƙarfe galibi ana rarraba su azaman kayan halitta. Waɗannan sun haɗa da beads na gilashi, kafofin watsa labarai na filastik, da nau'ikan hatsi irin su masara, sitaci na alkama, bawo, bawo na kwakwa, da bawo na goro. Ana amfani da abrasives na halitta lokacin da ake buƙatar ƙarancin lalacewar ƙasa.

Siffa da Taurin
Sauran la'akari lokacin zabar abrasive shine siffar jiki da taurin.

"Siffar abrasive zai ƙayyade inganci da sauri don tsarin fashewa," in ji Deardorff. "Abrasives masu kaifi, masu kaifi, ko rashin daidaituwa-siffa za su tsaftace da sauri kuma su daidaita saman da aka yi niyya. Zagaye ko abrasives mai siffar zobe zai tsaftace sassa ba tare da cire yawan adadin kayan tushe ba."

Taurin, a halin yanzu, yana rinjayar ba kawai saurin da yake tsaftacewa ba, har ma da yawan ƙurar da aka samar da kuma raguwa, wanda kuma yana da tasiri kai tsaye akan yiwuwar sake yin amfani da shi.

Ƙimar Mohs ne ke rarraba taurin abin ƙura - mafi girman lambar daga 1 (talc) zuwa 10 (lu'u-lu'u), mafi ƙarfin samfurin.
