4 Lintlha tsa bohlokoa bakeng sa khetho
I. Boikemisetso ba mofuta oa pompo ea ring ea vacuum ea metsi
Mofuta oa pompo ea "vacuum vacuum" ea mofuta oa metsi e khethoa haholo ke sebaka se pompetsoeng, bophahamo ba khase e hlokahalang, tekanyo ea vacuum kapa khatello ea ho tsoa.
II. Ea bobeli, pompo ea ring vacuum ea metsi e hloka ho ela hloko lintlha tse peli ka mor'a ts'ebetso e tloaelehileng.
1, Kahohle kamoo ho ka khonehang, boemo ba vacuum ba pompo e khethiloeng ea vacuum bo hlokeha ho ba ka har'a sebaka se phahameng sa ts'ebetso, ke hore, ho sebetsa sebakeng sa boemo ba bohlokoa bo hlokahalang ba vacuum kapa khatello e hlokahalang ea ho qeta, e le ho etsa bonnete ba hore hore pompo ea vacuum e ka sebetsa ka tloaelo ho latela maemo le litlhoko tse hlokahalang.Ts'ebetso e haufi le boemo bo phahameng ba vacuum kapa mofuta o phahameng oa khatello ea ho tsoa ha pompo ea vacuum e lokela ho qojoa.
Ho sebetsa sebakeng sena ha se hantle feela ho sa sebetseng hantle, empa hape ho tsitsitse haholo ebile ho tloaetse ho thothomela le lerata.Bakeng sa lipompo tsa vacuum tse nang le boemo bo phahameng ba ho hloekisa, bo sebetsang ka har'a sebaka sena, hangata cavitation e boetse e etsahala, e bonahalang ka lerata le ho thothomela ka har'a pompo ea ho hloekisa.Cavitation e feteletseng e ka lebisa tšenyo ho 'mele oa pompo, impeller le likarolo tse ling, e le hore pompo ea vacuum e se ke ea sebetsa hantle.
Ho ka bonoa hore ha khatello ea khase kapa khase e hlokoang ke pompo ea vacuum e se holimo, ho ka fanoa ka pele ho pompo ea mothati o le mong.Haeba tlhokahalo ea tekanyo ea vacuum kapa khatello ea khase e phahame, pompo ea mohato o le mong hangata ha e khone ho kopana le eona, kapa, tlhokahalo ea pompo e ntse e na le molumo o moholo oa khase tabeng ea tekanyo e phahameng ea vacuum, ke hore, tlhokahalo ea curve ea tshebetso. e boreleli ka tekanyo e phahameng ea vacuum, ho ka khethoa pompo ea mekhahlelo e 'meli.Haeba tlhokahalo ea vacuum e ka holimo ho -710mmHg, setsi sa vacuum sa metsi sa Roots se ka sebelisoa e le sesebelisoa sa ho pompa metsi.
2, Khetha ka nepo pompo ea vacuum ho latela matla a ho pompa a sistimi
Haeba mofuta oa pompo ea vacuum kapa yuniti ea vacuum e khethiloe, mohlala o nepahetseng o lokela ho khethoa ho latela matla a pompo a hlokahalang a sistimi.
Litšobotsi tsa mefuta e fapaneng ea lipompo tsa ring vacuum tsa metsi ke tse latelang.
