EF 25-120 Taxanaha Shaandhaynta Neefta
Nadiifiyaha heerkulka hawo -biyoodka ee ay soo saartay shirkadeena ayaa ah nooc cusub oo ah qalabka korontada, kuwaas oo leh sideed tilmaamood. Qaab -dhismeedka badeecadani wuxuu ka kooban yahay laba qaybood: hawadu aad bay u kulushahay saliiduna aad bay u kulushahay. Kaliya kama hortegi karto walxaha in lagu qaso habka shidaalka, sidaas darteedna loo fududeeyo qaab -dhismeedka haanta saliidda, laakiin sidoo kale waxay faa'iido u leedahay nadiifinta saliidda.
Marka la barbardhigo kuleyliyaha aan birta ahayn, badeecaddu waxay qaadataa budada naxaas-ka-samaysan ee macdanta leh ee kuleylka leh, taas oo leh astaamaha saxnaanta heer-ka-sarreeya, xoog xoog leh, baaxad xoog leh, kala-goynta habboon iyo dhaqidda, waxayna u adkeysan kartaa walaaca kuleylka iyo saameynta iyo shaqada sida caadiga ah heerkulka, iwm Sanadihii la soo dhaafay waxaa loo isticmaali jiray saliid badan oo nidaamka hidde -side ah oo waxoogaa is -le'eg.
Taxanaha noocan ah wuxuu leeyahay 8 moodeel. Waxaa ka mid ah shaandhaynta saliidda iyo shaandhaynta hawada. Shaandhaynta taxanaha EF oo lagu daray buuxinta saliidda ayaa si weyn loogu adeegsadaa haanta nidaamka haydarooliga. Shayga shaandhaynta wuxuu ka samaysan yahay budada naxaasta ah ee sintered ah, taas oo ku xoog badan khalkhalka, dhexgalka xasilloon oo u adkaysta heerkulka sare. Heerka saliidda ayaa kor u kici doonta ama hoos u dhici doonta inta lagu jiro hawlgalka nidaamka aalic hydr. Marka heerka saliidda uu kor u kaco, hawada ayaa laga saarayaa gudaha. Marka heerka saliidda uu hoos u dhaco, hawada ayaa dibedda looga soo dhici doonaa. Shaandhada neefsashada ayaa si toos ah loogu rakibi karaa daboolka haanta si loo shaandheeyo hawada neefsanaysa. Waxay kaloo noqon kartaa shaandho saliid. Marka saliidda lagu shubo taangiga iyada oo la marinayo shaandhaynta neefta, faddarada ayaa la sifeyn doonaa. Shaandhaynta neefsigu waxay ka dhigi kartaa taangiga mid nadiif ah oo waliba dheellitiri kara cadaadiska haanta. Waxay dheeraynaysaa nolosha adeegga qaybaha.
Marka nidaamka shidaalka uu shaqeeyo, dusha saliidda ayaa mararka qaarkood kor u kacda ama dhacda, waxayna ka soo baxdaa gudaha ilaa bannaanka.
Hawada saar, adiga oo hawo ka qaadaya bannaanka marka aad soo degayso. Si loo nadiifiyo saliidda ku jirta haanta, saliidda xoogaa waa la daboolaa
Dhibicda hawada ee toosan ayaa lagu rakibay sabuuradda, sidaas awgeed hawada la nuugo ayaa aad loo kululayn karaa. Isla mar ahaantaana, nadiifiyuhu hawo -mareenku waa afka saliidda lagu muday, oo saliidda cusub ee shaqaysa ee la muday waa in la sifeeyaa oo markaas la geliyaa haanta, si ay u daadiso walxaha wasakhaysan ee saliidda ku jira.
Nidaamka hiddaha, nadiifinta saliidda shaqaysa waa xiriir aad u muhiim ah. Nadiifiyaha baxsiga hawada ayaa saliidda ku jirta haanta saliidda nadiif noqon karta, kaliya ma ka hortagi karto in wasakhda wasakhdu ay gasho taangiga saliidda dibadda, laakiin sidoo kale waxay dheerayn kartaa wareegga shaqada iyo nolosha adeegga saliidda iyo qaybaha, si loo hubiyo hawlgalka caadiga ah ee nidaamka haydarooliga. Intaas waxaa sii dheer, marka nidaamka hawo -mareenku shaqeynayo, qulqulka hawada ayaa ilaalin kara dheelitirka u dhexeeya cadaadiska ku jira xoogaa saliid ah iyo cadaadiska jawiga, si looga fogaado suurtagalnimada in daloolka bamka.

Haddii dheecaanku yahay biyo-glycol, tusaalaha shaandhaynta neefsashadu waa EF3-40. BH
Fiiro gaar ah:
1. Heerka socodka hawada ee ku qoran shaxda waa qiimaha heerka socodka hawada 15m/s.
2. Tusaale ahaan, EF1-25, 1 waxaa loola jeedaa tusaalaha wakiilka, 25na waxaa loola jeedaa heerkulka hawada ee kululaaday iyo qiyaasta shidaalka ee 25mm.
3. Xaashida kulaylka badan waxay qaadataa macdanta budada ee ku salaysan naxaasta.
Muddo sanado ah shirkadayda oo leh unugyo cilmi -baaris cilmiyeed oo khuseeya iyo soo -saareyaasha heerkulka hawo -biyoodka wax -qabad farsamo oo cad ayaa la tijaabiyay, gunaanadku wuxuu yahay: heerkulka hawo -biyoodka qing alaabtu waxay shaqaysaa heerka socodka hawada, inta aan sii kordhineyno, iska caabbinta kuleylka ee wasakhaysan ayaa ka fiican, sidaa darteed, marka aad dooranayso cadaadiska dareeraha cadaadiska dareeraha alaabta qing waa inay lahaataa xuduud gaar ah, xaddiga socodka hawada ee bamka ayaa guud ahaan la doortay safka qiyaastii 1.5 ®.
