Kusankhidwa Kwa Viscosity Range Ndi Mfundo Ya Mafuta A Pampu Ya Vacuum

Ubwino wa vacuum pump mafuta makamaka zimatengera mamasukidwe akayendedwe ndi vacuum digiri, ndi vacuum digiri zimadalira mtengo pansi pa kutentha zosiyanasiyana.Kutentha kwapamwamba, kukhazikika kwa digiri ya vacuum ndi mafuta abwino.

Analimbikitsa vacuum mpope mafuta mamasukidwe akayendedwe osiyanasiyana
1. Piston vacuum pump (mtundu wa W) amatha kugwiritsa ntchito mafuta a injini wamba, ndikugwiritsa ntchito mafuta omwe ali ndi ma viscosity giredi a V100 ndi V150.
2. Rotary vane vacuum pump (mtundu wa 2X) amagwiritsa ntchito V68, V100 viscosity grade grade mafuta.
3. Pampu ya rotary vane vacuum yolumikizana mwachindunji (yothamanga kwambiri) (mtundu wa 2XZ) imagwiritsa ntchito mafuta a V46 ndi V68 viscosity grade
4. Pampu ya slide vacuum vacuum (mtundu H) imasankha V68, V100 viscosity grade grade mafuta.
5. Mapampu a Trochoidal vacuum (YZ, YZR) amagwiritsa ntchito mafuta a V100, V150 viscosity grade.
6. Pakupaka mafuta amtundu wamagetsi a Roots vacuum pump (mechanical booster pump), V32 ndi V46 vacuum pump mafuta angagwiritsidwe ntchito.

Mfundo yosankha mamasukidwe akayendedwe
Kusankhidwa kwa viscosity yamafuta ndichimodzi mwazinthu zofunika pakugwirira ntchito kwapampu ya vacuum.Kukhuthala kwamadzimadzi ndiko kukana kuyenda kwamadzimadzi, kapena kukangana kwamkati kwamadzimadzi.Kuchuluka kwa viscosity, kumapangitsanso kukana kuthamanga kwa magawo osiyanasiyana,
Kutentha kumawonjezeka, ndipo kutaya mphamvu kumakhala kwakukulu;kukhuthala kwake ndi kochepa kwambiri, ndipo ntchito yosindikiza ya mpope imakhala yosauka, zomwe zimayambitsa kutuluka kwa mpweya ndi kuwonongeka kwa vacuum.Chifukwa chake, kusankha makulidwe amafuta pamapampu osiyanasiyana a vacuum ndikofunikira kwambiri.Mfundo ya kusankha mafuta mamasukidwe akayendedwe ndi:
1. Kuthamanga kwapamwamba kwa mpope, kumachepetsa kukhuthala kwa mafuta osankhidwa.
2. Kukwera kwa liwiro la mzere wa rotor wa mpope, kumachepetsa kukhuthala kwa mafuta osankhidwa.
3. Kuwongolera kulondola kwa makina a pampu kapena kucheperachepera kusiyana pakati pa zigawo zotsutsana, kumachepetsa kukhuthala kwa mafuta osankhidwa.
4. Pamene pampu ya vacuum ikugwiritsidwa ntchito pa kutentha kwakukulu, ndi bwino kusankha mafuta apamwamba kwambiri a viscosity.
5. Pamapampu a vacuum okhala ndi madzi ozizira, ndibwino kugwiritsa ntchito mafuta omwe ali ndi kukhuthala kochepa.
7. Kwa mitundu ina ya mapampu a vacuum, mafuta ofananira amatha kusankhidwa molingana ndi liwiro lake, kulondola kwa processing, vacuum yotsiriza, ndi zina zotero.

Viscosity Index ndi Viscosity
Kawirikawiri, anthu amaganiza kuti pamene "viscous" zambiri zimakhala bwino, zimakhala bwino.Ndipotu izi sizili choncho."Woonda" ndi "yomata" amangoyang'ana pang'onopang'ono komanso kumva m'manja kwa DVC, DVE VG22, 32, ndi 46, ndipo palibe zambiri.Ngati ma viscosity amafuta awiriwa ndi ofanana pa 40 ° C, mafuta akazizira kutentha, mafuta "oonda" ndi abwino kuposa mafuta "okhazikika".Chifukwa mafuta "oonda" ali ndi index yayikulu ya viscosity kuposa mafuta "yomata".Kukhuthala kwa mafuta a viscous kumasintha kwambiri ndi kusintha kwa kutentha, ndiko kuti, index ya mamasukidwe amachepa, ndipo index mamasukidwe akayendedwe ndi chizindikiro chofunika vacuum mpope mafuta.Mafuta a pompo omwe ali ndi index yayikulu ya viscosity amakhala ndi kusiyanasiyana kocheperako ndi kutentha.Komanso, pampu yozizira ndiyosavuta kuyamba ndipo imakhala ndi zotsatira zopulumutsa mphamvu kwambiri.Makamaka m'chilimwe, pamene kutentha kozungulira ndi kutentha kwa mafuta mu mpope kumawuka, kuchepetsa kupanikizika kwa mafuta kumatha kukhalabe ndi zotsatira zabwino.
