Sababtoo ah sifooyinka jireed iyo kiimikaad ee alaabta dareeraha ah way kala duwan yihiin, waxaa jira shuruudo buuxin oo kala duwan inta lagu jiro buuxinta.Qalabka dareeraha ah waxaa lagu buuxiyaa weelka baakadaha iyada oo la adeegsanayo qalabka kaydinta dareeraha ah (badanaa loo yaqaan haanta kaydinta dareeraha), hababka soo socda ayaa badanaa la isticmaalaa.
1) Buuxinta cadaadiska caadiga ah
Buuxinta cadaadiska caadiga ah waa in si toos ah loogu tiirsanaado culeyska nafteeda ee walxaha dareeraha ka buuxaan si ay ugu qulqulaan weelka baakadaha ee cadaadiska jawiga.Mashiinka buuxiya alaabada dareeraha ah weelasha baakadaha ee cadaadiska atmospheric waxaa loo yaqaan mashiinka buuxinta atmospheric.Habka buuxinta cadaadiska atmospheric waa sida soo socota:
① Dareeraha iyo qiiqa soo gelitaanka, taas oo ah, walxaha dareeraha ah ayaa galaya weelka oo hawada ku jirta weelka ayaa la sii daayaa isku mar;
② Jooji quudinta dareeraha, taas oo ah, marka walxaha dareeraha ah ee ku jira weelka ay buuxiyaan shuruudaha tirada, quudinta dareeraha ayaa si toos ah u joogsan doonta;
③ Daadi dareeraha haraaga ah, ie daadi dareeraha haraaga ah ee ku jira tuubada qiiqa, taas oo lagama maarmaan u ah dhismayaasha ku qiiqaya qolka hawada sare ee kaydka.Cadaadiska atmospheric waxaa inta badan loo isticmaalaa buuxinta viscosity hoose iyo walxaha dareeraha ah ee gaaska, sida caanaha, Baijiu, suugo soy ah, potion iyo wixii la mid ah.
2) Buuxinta isobaric
Buuxinta Isobaric waxay isticmaashaa hawada cufan ee qolka hawada sare ee haanta kaydinta dareeraha si ay u buufiso weelka baakadaha si labada cadaadis ay ugu dhawaadaan inay siman yihiin, ka dibna dareeraha ka buuxsamay wuxuu ku qulqulaa weelka miisaankiisa.Mashiinka buuxinta ee isticmaalaya habka isobaric waxaa loo yaqaan mashiinka buuxinta isobaric'
Habka farsamada ee buuxinta isobaric waa sida soo socota: ① sicir bararka isobaric;② Soo gelida dareeraha ah iyo soo celinta gaaska;③ Jooji quudinta dareeraha;④ Cadaadiska sii daa, taas oo ah, sii daaya gaaska isku-buufiska ah ee haraaga ah ee ku jira cirifka dhalooyinka jawiga si looga fogaado tiro badan oo goobooyin ah oo ay sababtay hoos u dhigista cadaadiska degdega ah ee dhalada, taas oo saameyn doonta tayada baakadaha iyo saxnaanta tirada.
Habka isobaric ayaa lagu dabaqi karaa buuxinta cabitaannada hawada laga saaray, sida biirka iyo soodhaha, si loo yareeyo khasaaraha gaaska (CO ν) ee ku jira.
3) Buuxinta faakuumka
Buuxinta faakuumka waxaa lagu fuliyaa xaalad ka hooseysa cadaadiska atmospheric.Waxay leedahay laba hab oo aasaasi ah: mid waa nooca vacuum cadaadiska kala duwan, taas oo ka dhigaysa gudaha haanta kaydinta dareeraha cadaadis caadi ah, oo kaliya daalin gudaha gudaha weelka baakadaha si ay u sameeyaan vacuum gaar ah.Walxaha dareeraha ah waxay ku qulqulaan weelka baakadaha waxayna dhammaystiraan buuxinta iyagoo ku tiirsan farqiga cadaadiska u dhexeeya labada weel;Midda kale waa nooca vacuum cufis-jiidad, kaas oo ka dhigaya taangiga kaydinta dareeraha ah iyo awoodda baakadaha Waqtigan xaadirka ah, nooca cadaadiska kala duwan ee vacuum waxaa caadi ahaan loo isticmaalaa Shiinaha, kaas oo leh qaab-dhismeed fudud iyo hawlgal lagu kalsoonaan karo.
Habka buuxinta faakuumka waa sida soo socota: ① faaruqi dhalada;② gudaha iyo qiiqa;③ joojinta dareeraha dareeraha ah;④ dareeraha soo noqnoqda, taas oo ah, dareeraha hadha ee tuubada qiiqa waxay ku soo noqotaa haanta kaydinta dareeraha iyada oo loo marayo qolka faakuumka.
Habka Vacuum wuxuu ku habboon yahay buuxinta walxaha dareeraha leh viscosity wax yar ka sarreeya (sida saliidda, sharoobada, iwm.), walxaha dareeraha ah ee ay ku jiraan fiitamiinada (sida casiirka khudradda, casiirka khudradda, iwm.) iyo walxaha dareeraha sunta ah (sida sunta cayayaanka, iwm.) ) Habkani ma hagaajin karo oo kaliya xawaaraha buuxinta, laakiin sidoo kale wuxuu yareeyaa xidhiidhka iyo ficilka u dhexeeya walxaha dareeraha ah iyo hawada hadhaaga ah ee weelka, sidaas darteed waxay ku haboon tahay in la dheereeyo nolosha kaydinta alaabta qaarkood.Intaa waxaa dheer, waxay xaddidi kartaa baxsashada gaaska sunta ah iyo dareeraha, si loo hagaajiyo xaaladaha hawlgalka.Si kastaba ha ahaatee, kuma habboona buuxinta khamriga ay ku jiraan gaasaska udgoonka, sababtoo ah waxay kordhin doontaa luminta udgoonka khamriga.
4) Buuxinta cadaadiska
Buuxinta cadaadisku waa in la xakameeyo dhaqdhaqaaqa is-beddelka ee piston-ka iyadoo la kaashanayo aaladaha hydraulic makaanikada ama pneumatic, nuug walxaha dareeraha leh viscosity sare gudaha dhululubada piston ee dhululubada kaydinta, ka dibna si qasab ah ugu riix weelka si loo buuxiyo.Habkan waxaa mararka qaarkood loo isticmaalaa buuxinta cabitaannada fudud sida cabitaannada fudud.Sababtoo ah kuma jiraan walxaha kolloidal, samaynta xumbo waa sahlan tahay in la waayo, sidaas darteed waxay si toos ah ugu shubi kartaa dhalooyin aan horay loo buuxin adoo ku tiirsan xooggeeda, sidaas darteed si weyn u kordhinaysa xawaaraha buuxinta.5) Buuxinta Siphon buuxinta siphon waa in la isticmaalo mabda'a siphon si loo sameeyo walxaha dareeraha ah ee lagu nuugo weelka laga soo bilaabo haanta kaydinta dareeraha iyada oo loo marayo tuubada siphon ilaa labada heer ee dareeraha ah ay siman yihiin.Habkani wuxuu ku habboon yahay buuxinta walxaha dareeraha leh maqaar hooseeya oo aan lahayn gaas.Waxay leedahay qaab-dhismeed fudud laakiin xawaare buuxin hooseeya.
