Boleng ba oli ea pompo ea vacuum bo ipapisitse le boemo ba viscosity le vacuum degree, 'me tekanyo ea vacuum e itšetlehile ka boleng tlas'a maemo a fapaneng a mocheso.Ha mocheso o phahame, ts'ebetso e tsitsitseng ea tekanyo ea vacuum ke oli e ntle.
E khothalelitsoeng mefuta e fapaneng ea viscosity ea oli ea pompo ea vacuum
1. Piston vacuum pump (mofuta oa W) e ka sebelisa oli e tloaelehileng ea enjene, 'me ea sebelisa lihlahisoa tsa oli tse nang le limaraka tsa viscosity tsa V100 le V150.
2. Rotary vane vacuum pump (mofuta oa 2X) o sebelisa V68, V100 viscosity grade grade.
3. Pompe ea vacuum ea rotary (mofuta oa 2XZ) e kopantsoeng ka ho toba (lebelo le phahameng) e sebelisa lihlahisoa tsa oli tsa V46 le V68 viscosity grade.
4. Pompo ea vacuum ea li-slide valve (mofuta oa H) e khetha V68, V100 oli ea likhalase tsa viscosity.
5. Trochoidal vacuum pumps (YZ, YZR) sebelisa V100, V150 viscosity grade oli.
6. Bakeng sa lubrication ea gear transmission system ea Roots vacuum pump (mechanical booster pump), V32 le V46 vacuum pump oli e ka sebelisoa.
Molao-motheo oa khetho ea viscosity
Khetho ea viscosity ea oli ke e 'ngoe ea lintlha tsa bohlokoa bakeng sa ts'ebetso ea pompo ea vacuum.The viscosity ea mokelikeli ke ho hanyetsa ho phalla ha mokelikeli, kapa khohlano ea ka hare ea mokelikeli.Ha viscosity e le kholoanyane, ho hanyetsa lebelo la motsamao oa likarolo tse fapaneng,
Mocheso oa eketseha, 'me tahlehelo ea matla e kholo;viscosity e nyane haholo, 'me ts'ebetso ea tiiso ea pompo ea fokola, e baka ho lutla ha khase le ho senyeha ha vacuum.Ka hona, khetho ea viscosity ea oli bakeng sa lipompo tse fapaneng tsa vacuum e bohlokoa haholo.Molao-motheo oa khetho ea oli ea viscosity ke:
1. Ha lebelo la pompo le phahame, le theola viscosity ea oli e khethiloeng.
2. Ho phahama ha lebelo la lebelo la rotor ea pompo, ho fokotsa viscosity ea oli e khethiloeng.
3. Ho nepahala ha machining ea likarolo tsa pompo kapa ho fokotsa lekhalo pakeng tsa likarolo tse ferekaneng, ho fokotsa viscosity ea oli e khethiloeng.
4. Ha pompo ea vacuum e sebelisoa maemong a phahameng a mocheso, ho eletsoa ho khetha oli e phahameng ea viscosity.
5. Bakeng sa lipompo tsa vacuum tse nang le potoloho ea metsi a pholileng, ka kakaretso ho eletsoa ho sebelisa oli e nang le viscosity e tlaase.
7. Bakeng sa mefuta e meng ea lipompo tsa vacuum, oli e tsamaellanang e ka khethoa ho ea ka lebelo la eona, ho nepahala ha ts'ebetso, vacuum ea ho qetela, joalo-joalo.
Viscosity Index le Viscosity
Ka kakaretso, batho ba nahana hore ha "viscous" e le ngata, ho molemo.Ha e le hantle, ha ho joalo."Thin" le "sticky" ke tlhahlobo ea pono e lekanyelitsoeng le maikutlo a letsoho a DVC, DVE VG22, 32, le 46, 'me ha ho na data ea bongata.Haeba litekanyetso tsa viscosity tsa oli tse peli li tšoana le 40 ° C, ha oli e pholile ho mocheso oa kamore, oli "e tšesaane" e molemo ho feta oli "e khomarelang".Hobane oli e "tšesaane" e na le index e phahameng ea viscosity ho feta "lioli tse khomarelang".Viscosity ea oli ea viscous e fetoha haholo ka phetoho ea mocheso, ke hore, index ea viscosity e tlase, 'me index ea viscosity ke pontšo ea bohlokoa ea oli ea pompo ea vacuum.Oli ea pompo e nang le index e phahameng ea viscosity e na le phapang e fokolang ea viscosity le mocheso.Ho feta moo, pompo e batang e bonolo ho qala 'me e na le phello ea ho boloka matla a matla haholo.Haholo-holo lehlabula, ha mocheso o le teng le mocheso oa oli ka pompong o phahama, khatello ea moeli oa oli e ka boloka phello e ntle.
