Tayada saliidda bamka faakuumka waxay inta badan ku xidhan tahay viscosity iyo degree vacuum, iyo heerka faakuumku waxay ku xidhan tahay qiimaha xaaladaha heerkulka kala duwan.Heerkulka sare, ayaa si aad ah u deggan waxqabadka darajada faakuumka waa saliidda wanaagsan.
Qiyaasta viscosity ee saliidda matoorka ee lagu taliyay
1. Piston vacuum pump (nooca W) wuxuu isticmaali karaa saliidda injiinka caadiga ah, wuxuuna isticmaali karaa alaabada saliidda ee leh buundooyinka viscosity ee V100 iyo V150.
2. Rotary vane vacuum pump (nooca 2X) wuxuu isticmaalaa V68, V100 saliid heerka viscosity.
3. Bamamka faakuumka ee tooska ah ee isku xidhan (xawaaraha sare) ee rotary vane vacuum pump (nooca 2XZ) waxa uu isticmaalaa V46 iyo V68 wax soo saarka saliidda heerka viscosity
4. Bamamka faakuumka ee salida valve (nooca H) ayaa doorta V68, V100 saliid heerka viscosity.
5. Trochoidal vacuum pumps (YZ, YZR) waxay isticmaalaan V100, V150 saliidaha heerka viscosity.
6. Sifeynta nidaamka gudbinta marsho ee Roots vacuum pump (matoorka xoojisa makaanikada), V32 iyo V46 saliidda bamka vacuum ayaa loo isticmaali karaa.
Mabda'a xulashada viscosity
Xulashada viscosity saliiddu waa mid ka mid ah qodobbada muhiimka ah ee waxqabadka bamka vacuum.Viscosity dareere waa caabbinta qulqulka dareeraha, ama khilaafka gudaha ee dareeraha.Inta badan viscosity-ku, way sii weynaataa caabbinta xawaaraha dhaqdhaqaaqa qaybaha kala duwan.
Heerkulka ayaa kor u kaca, iyo khasaaraha korontadu waa weyn yahay;viscosity aad buu u yar yahay, iyo wax qabadka xidhidhiyaha bamka ayaa noqda mid liidata, taasoo keenaysa daadinta gaaska iyo faakuumka sii xumaanaya.Sidaa darteed, xulashada viscosity saliidda ee matoorada faakuumka kala duwan ayaa aad muhiim u ah.Mabda'a xulashada viscosity oil waa:
1. Xawaaraha bamka ayaa sarreeya, hoos u dhaca viscosity ee saliidda la doortay.
2. Mar kasta oo xawaaraha tooska ah ee rotor ee bamka, ayaa hoos u dhigaya viscosity ee saliidda la doortay.
3. Sida ugu fiican ee saxnaanta mashiinada qaybaha bamka ama farqiga u dhexeeya qaybaha is-jiidhka, hoos u dhaca viscosity ee saliidda la doortay.
4. Marka bamka faakuumka loo isticmaalo xaaladaha heerkulka sare, waxaa lagu talinayaa in la doorto saliid viscosity sare leh.
5. Matoorada faakuumka leh ee qaboojinta wareegga biyaha, guud ahaan waxaa lagula talinayaa in la isticmaalo saliid leh maqaar hoose.
7. Noocyada kale ee bambooyinka faakuumka, saliidda u dhiganta waxaa lagu dooran karaa iyadoo loo eegayo xawaaraha, saxnaanta farsamaynta, faakuumka kama dambaysta ah, iwm.
Tilmaamaha Viscosity iyo Viscosity
Guud ahaan, dadku waxay u maleynayaan in mar kasta oo "mujis" ah oo faaruq ah, ay ka sii wanaagsan tahay.Dhab ahaantii, arrintu sidaas maaha."Qafiif ah" iyo "dhegeysan" waa uun indho-indhayn muuqaal ah iyo dareenka gacanta ee DVC, DVE VG22, 32, iyo 46, mana jirto xog tiro badan.Haddii qiimaha viscosity ee labada saliid ay isku mid yihiin 40 ° C, marka saliidaha la qaboojiyo heerkulka qolka, saliidda "dhuuban" waxay ka fiican tahay saliidda "dhegeysan".Sababtoo ah saliidaha "dhuuban" waxay leeyihiin index of viscosity ka sarreeya saliidaha "dhegeysan".Viscosity ee saliidda viscosity si weyn ayey isu beddeshaa isbeddelka heerkulka, taas oo ah, index viscosity waa hooseeyaa, index viscosity index waa tilmaame muhiim ah oo ku saabsan saliidda bamka vacuum.Saliidaha bamka ee leh tusmada viscosity-ga sare waxay leeyihiin kala duwanaansho yar xagga mawqifka heerkulka.Waxaa intaa dheer, bamka qabowgu waa sahlan tahay in la bilaabo wuxuuna leeyahay saameynta si weyn loo badbaadiyo isticmaalka tamarta.Gaar ahaan xagaaga, sida heerkulka deegaanka iyo heerkulka saliidda ee bamka ayaa kor u kacaya, cadaadiska xaddidan ee saliidda ayaa ilaalin kara saameyn wanaagsan.
