Izinga likawoyela wepompo le-vacuum lincike ikakhulukazi ku-viscosity kanye ne-vacuum degree, futhi idigri ye-vacuum incike enanini ngaphansi kwezimo ezihlukene zokushisa.Uma izinga lokushisa liphakeme, ukusebenza kwe-vacuum degree kuzinzile kakhulu amafutha amahle.
Ibanga le-viscosity likawoyela wepompo ye-vacuum elinconyiwe
1. Iphampu ye-piston vacuum (uhlobo luka-W) ingasebenzisa uwoyela wenjini evamile, futhi isebenzise imikhiqizo kawoyela enamabanga e-viscosity angu-V100 kanye ne-V150.
2. Iphampu ye-Rotary vane vacuum (uhlobo 2X) isebenzisa i-V68, i-V100 uwoyela webanga le-viscosity.
3. Iphampu yevacuum ye-rotary ehlanganisiwe ehlanganisiwe (isivinini esikhulu) (uhlobo 2XZ) isebenzisa imikhiqizo kawoyela yezinga le-V46 ne-V68.
4. Ipompo yevacuum ye-valve yesilayidi (uhlobo H) ikhetha i-V68, i-V100 yamafutha ebanga le-viscosity.
5. Amaphampu e-Trochoidal vacuum (YZ, YZR) asebenzisa i-V100, i-V150 viscosity grade amafutha.
6. Ukuze kugcotshwe isistimu yokudlulisa igiya ye-Roots vacuum pump (i-mechanical booster pump), i-V32 kanye ne-V46 vacuum futha amafutha angasetshenziswa.
Umgomo wokukhetha i-viscosity
Ukukhethwa kwe-viscosity kawoyela kungenye yezinto ezibalulekile ekusebenzeni kwepompo ye-vacuum.I-viscosity yoketshezi ukumelana nokugeleza koketshezi, noma ukungqubuzana kwangaphakathi koketshezi.I-viscosity enkulu, ukumelana okukhulu nesivinini sokunyakaza kwezingxenye ezihlukahlukene,
Izinga lokushisa liyakhula, futhi ukulahlekelwa kwamandla kukhulu;i-viscosity incane kakhulu, futhi ukusebenza kokuvala kwepompo kuba mpofu, okubangela ukuvuza kwegesi kanye nokuwohloka kwe-vacuum.Ngakho-ke, ukukhethwa kwe-viscosity kawoyela yamaphampu e-vacuum ahlukahlukene kubaluleke kakhulu.Umgomo wokukhetha i-viscosity kawoyela uthi:
1. Ijubane eliphezulu lepompo, i-viscosity ephansi yamafutha akhethiwe iyancipha.
2. Ukuphakama kwesivinini somugqa we-rotor yepompo, i-viscosity yamafutha akhethiwe iphansi.
3. Ukunciphisa ukunemba kwemishini yezingxenye zepompo noma igebe elincane phakathi kwezingxenye zokungqubuzana, i-viscosity ephansi yamafutha akhethiwe iyancipha.
4. Uma ipompo ye-vacuum isetshenziswa ezimweni zokushisa eziphakeme, kuhle ukukhetha amafutha aphezulu e-viscosity.
5. Amaphampu e-vacuum ane-circulation yamanzi okupholisa, ngokuvamile kuyalulekwa ukusebenzisa amafutha ane-viscosity ephansi.
7. Kwezinye izinhlobo zamaphampu we-vacuum, amafutha ahambisanayo angakhethwa ngokuvumelana nesivinini sawo, ukunemba kokucubungula, i-vacuum yokugcina, njll.
I-Viscosity Index kanye ne-Viscosity
Ngokuvamile, abantu bacabanga ukuthi lapho "i-viscous" eyengeziwe, i-vacuum ingcono.Eqinisweni, akunjalo.“Okuncane” nokuthi “okunamathelayo” kuwukuhlola okuhlobene okubonakalayo nomuzwa wesandla we-DVC, DVE VG22, 32, kanye 46, futhi ayikho idatha yobuningi.Uma amanani we-viscosity wamafutha amabili afana no-40 ° C, lapho amafutha epholile ekamelweni lokushisa, amafutha "amancane" angcono kunamafutha "anamathele".Ngoba amafutha "amancane" anenkomba ephezulu ye-viscosity kunamafutha "okunamathelayo".I-viscosity yamafutha e-viscous ishintsha kakhulu ngokushintsha kwezinga lokushisa, okungukuthi, inkomba ye-viscosity iphansi, futhi inkomba ye-viscosity iyinkomba ebalulekile yamafutha epompo ye-vacuum.Amafutha epompo anenkomba ye-viscosity ephezulu anokwehluka okuncane ku-viscosity nezinga lokushisa.Ngaphezu kwalokho, ipompo ebandayo kulula ukuyiqala futhi inomphumela wokonga kakhulu ukusetshenziswa kwamandla.Ikakhulukazi ehlobo, njengoba izinga lokushisa elizungezile kanye nokushisa kwamafutha epompo likhuphuka, ukucindezela komkhawulo kawoyela kungagcina umphumela omuhle.
