Sidee loo doortaa saliidda matoorka saxda ah?

Tayada saliidda bamka faakuumka waxay kuxirantahay viscosity iyo vacuum degree, iyo heerka faakuumku waxay kuxirantahay qiimaha heerkul kala duwan.Markasta oo heerkulku sarreeyo, heerka vacuumku waa uu xasiloon yahay. Aan wax badan ka barano waxyaabaha soo socda:
I.Nuxurka viscosity saliid ee lagu taliyay ee bamka faakuumka:
i.Bamka faakuumka ee piston (nooca W) wuxuu isticmaalaa saliidda injiinka guud, oo leh V100 iyo V150 saliid heerka viscosity.
ii.Bamamka faakuumka ee Rotary vane (nooca 2x) wuxuu isticmaalaa v68 iyo V100 saliid heerka viscosity.

iii.Bamamka faakuumka ee rotary vane vacuum (nooca 2XZ) ee si toos ah ugu xidhan (xawaaraha sare) wuxuu isticmaalaa saliid heerka viscosity V46 iyo V68.
iv.Bamamka faakuumka ee salida waalka (nooca H) waxay isticmaalaan v68 iyo V100 saliid heerka viscosity.
v. V32 iyo v46 saliid faaruq ah waxaa loo isticmaali karaa sifaynta ee Roots vacuum pump (matoorka xoojisa makaaniga) nidaamka gudbinta marsho.

II.Mabda'a xulashada viscosity
Xulashada viscosity saliidda waa mid ka mid ah qodobbada muhiimka ah ee waxqabadka bamka vacuum.The viscosity ee dareeraha ah waa caabbinta dareeraha si ay u qulqulaan, ama khilaafka gudaha ee dareeraha. xawaaraha socodka ee qaybaha kala duwan, kor u kaca heerkulka sare iyo weyn ee khasaaraha korontada; Haddii viscosity waa mid aad u yar, waxqabadka shaabadeynta ee bamka ayaa noqda mid liidata, taasoo keentay in daadinta gaaska iyo faakuum liita.Sidaas darteed, bambooyin vacuum kala duwan ayaa aad u badan. muhiim u ah doorashada of viscosity saliid.Mabaadi'da xulashada viscosity saliid waa sida soo socota:
i.Xawaaraha bamka ayaa sarreeya, hoos u dhaca viscosity ee saliidda la doortay.
ii.Xawaaraha tooska ah ee dhaqdhaqaaqa rotor bamka weyn, ayaa hoos u dhigaya viscosity ee saliidda la doortay.
iii.Sida saxda ah ee saxnaanta mishiinada qaybaha matoorka ama yaraynta nadiifinta u dhaxaysa qaybaha isjiidka, ayaa hoos u dhigaya viscosity ee saliidda la doortay.
iv.Marka bamka faakuumka loo isticmaalo xaaladaha heerkulka sare, waxay ku habboon tahay in la doorto saliidda leh maqaar sare.
v. Bamka faakuumka leh ee qaboojinta wareegga biyaha, saliidda mawqifkoodu hooseeyo waa in guud ahaan la doortaa.
Noocyada kale ee matoorada vacuum, alaabta saliidda ee u dhiganta waxaa lagu dooran karaa iyadoo loo eegayo xawaaraha wareega, saxnaanta farsamaynta, faakuumka xad dhaafka ah, iwm.

Haddii bamka faakuumka aan si joogto ah loo beddelin oo aan gacanta lagu hayn inta lagu jiro muddada dheer, saliidda bamka-fududku waa la emulsified ama kaarboonaysmayn doonaa, taasoo ka dhalanaysa dhibaatooyin taxane ah sida xidhashada dhululubada bamka faakuumka, xannibaadda dhuumaha saliidda iyo filtarrada saliidda. Haddii kala-duwayaasha ceeryaamaha saliidda la xannibo, gaasta lagu shubo bamka si fudud uma dami doono.Waqtigaan, cadaadiska gudaha ee jirka bamka ayaa aad u sarreeya, xawaaraha bamka ayaa hoos u dhacaya, taasoo keentay hoos u dhaca heerka vacuum.Sidaas darteed, beddel saliidda bamka vacuum waqtigeeda.
