Hunhu hwevacuum pombi yemafuta inonyanya kuenderana neiyo viscosity uye vacuum degree, uye iyo vacuum degree inoenderana nekukosha pasi pemamiriro ekushisa akasiyana.Iyo yakakwirira tembiricha, iyo yakanyanya kugadzikana kuita kwevacuum degree ndiyo yakanaka mafuta.
Yakakurudzirwa vacuum pombi mafuta viscosity renji
1. Piston vacuum pombi (W mhando) inogona kushandisawo mafuta einjini, uye kushandisa zvigadzirwa zvemafuta zvine viscosity mamakisi eV100 neV150.
2. Rotary vane vacuum pombi (mhando 2X) inoshandisa V68, V100 viscosity giredhi oiri.
3. Iyo yakananga-yakabatana (yakakwira-kumhanya) rotary vane vacuum pombi (rudzi 2XZ) inoshandisa V46 uye V68 viscosity giredhi zvigadzirwa zvemafuta.
4. Slide valve vacuum pump (rudzi H) inosarudza V68, V100 viscosity grade mafuta.
5. Trochoidal vacuum pumps (YZ, YZR) inoshandisa V100, V150 viscosity grade mafuta.
6. Nekuzora kwegear transmission system yeRoots vacuum pombi (mechanical booster pump), V32 uye V46 vacuum pombi mafuta anogona kushandiswa.
Nheyo yekusarudza viscosity
Kusarudzwa kwemafuta viscosity chimwe chezvinhu zvakakosha zvevacuum pombi kuita.Iyo viscosity yemvura ndiko kuramba kuyerera kwemvura, kana kukwesha kwemukati kwemvura.Iyo yakakura viscosity, iyo yakakura kuramba kumhanyisa kwekufamba kwezvikamu zvakasiyana,
Kupisa kunowedzera, uye kurasikirwa kwesimba kwakakura;iyo viscosity idiki zvakanyanya, uye yekuvharisa kuita kwepombi kunova kwakashata, zvichikonzera kubuda kwegasi uye kuparara kwevacuum.Naizvozvo, kusarudzwa kwemafuta viscosity kune akasiyana vacuum pombi kwakakosha zvakanyanya.Nheyo yekusarudzwa kwemafuta viscosity ndeiyi:
1. Iyo yakakwirira kukurumidza kwepombi, yakaderera viscosity yemafuta akasarudzwa.
2. Iyo yakakwirira yelinear velocity ye rotor yepombi, yakaderera viscosity yemafuta akasarudzwa.
3. Iyo yakanakisa machining accuracy yepombi zvikamu kana kuti madiki gap pakati pezvikamu zvekukweshana, yakaderera iyo viscosity yemafuta akasarudzwa.
4. Kana pombi yevacuum inoshandiswa mumamiriro ekupisa, zvinokurudzirwa kusarudza mafuta akakwirira eviscosity.
5. Pamapombi evacuum ane kutenderera kwemvura inotonhorera, zvinowanzokurudzirwa kushandisa mafuta ane yakaderera viscosity.
7. Kune mamwe marudzi epombi yevacuum, mafuta anoenderana anogona kusarudzwa maererano nekumhanya kwayo, kugadzirisa kunyatsoita, yekupedzisira vacuum, nezvimwewo.
Viscosity Index uye Viscosity
Kazhinji, vanhu vanofunga kuti zvakanyanya "viscous" vacuum, zviri nani.Kutaura zvazviri, izvi hazvisizvo."Mutete" uye "kunamira" ingori hukama hwekutarisa uye kunzwa kweruoko rweDVC, DVE VG22, 32, uye 46, uye hapana huwandu hwe data.Kana maitiro e-viscosity emafuta maviri akafanana pa40 ° C, kana mafuta acho akanyoroveswa kusvika kukushisa kwekamuri, mafuta "akaonda" ari nani pane "sticky" mafuta.Nekuti "matete" maoiri ane yakakwira viscosity index pane "sticky" mafuta.Iyo viscosity yemafuta e-viscous inoshanduka zvakanyanya nekuchinja kwekushisa, ndiko kuti, iyo viscosity index yakaderera, uye iyo viscosity index chiratidzo chakakosha chevacuum pombi mafuta.Mafuta epombi ane high viscosity index ane zvishoma zvakasiyana muviscosity nekushisa.Uyezve, pombi inotonhora iri nyore kutanga uye ine mhedzisiro yekuchengetedza zvakanyanya kushandiswa kwesimba.Kunyanya muzhizha, sezvo tembiricha ye ambient uye tembiricha yemafuta mupombi inokwira, iyo inogumira kudzvanywa kweoiri inogona kuchengetedza mhedzisiro yakanaka.
