Iphampu yemishini ibizwa nangokuthi iphampu yangaphambi kwesigaba, futhi ingenye yamaphampu e-vacuum aphansi asetshenziswa kakhulu, esebenzisa uwoyela ukugcina umphumela wokuvala futhi ithembele ezindleleni zemishini ukushintsha njalo ivolumu yesikhala sokumunca ephampuni, ukuze ivolumu yegesi esitsheni esipompiwe inwetshwe njalo ukuze kutholakale i-vacuum. Kunezinhlobo eziningi zamaphampu emishini, avamile uhlobo lwe-slide valve, uhlobo lwe-piston reciprocating, uhlobo lwe-vane oluhleliwe kanye nohlobo lwe-rotary vane.
Izingxenye zamaphampu omshini
Iphampu yemishini ivame ukusetshenziselwa ukupompa umoya owomile, kodwa ayikwazi ukupompa okuqukethwe okuphezulu komoya-mpilo, amagesi aqhumayo nagqwalayo, amaphampu emishini ngokuvamile asetshenziselwa ukupompa igesi ehlala njalo, kodwa ayinawo umphumela omuhle emanzini nasegesini, ngakho ayikwazi ukupompa amanzi nasegesini. Izingxenye ezidlala indima eyinhloko kuphampu ye-rotary vane yi-stator, i-rotor, i-shrapnel, njll. I-rotor ingaphakathi kwe-stator kodwa ine-axis ehlukile ku-stator, njengezindilinga ezimbili zangaphakathi ezi-tangent, i-rotor slot ifakwe izingcezu ezimbili ze-shrapnel, phakathi kwezingcezu ezimbili ze-shrapnel ifakwe isiphethu ukuqinisekisa ukuthi i-shrapnel inamathele ngokuqinile odongeni lwangaphakathi lwe-stator.
Isimiso sokusebenza kwepompo yemishini
Ama-shrapnel ayo amabili adlala indima ezimbili ngokushintshana, ngakolunye uhlangothi, emunca igesi evela endaweni yokungena, kanti ngakolunye uhlangothi, ecindezela igesi esivele imuncwe futhi ekhipha igesi epompo. I-Rotor njalo ngomjikelezo wokujikeleza, ipompo iqeda ukumunca okubili kanye nokumunca okubili.
Uma ipompo ijikeleza njalo ngokwewashi, ipompo ye-rotary vane idonsa njalo igesi ngaphakathi kokungena bese iyikhipha echwebeni lokukhipha umoya ukuze kufezwe injongo yokupompa isitsha. Ukuze kuthuthukiswe i-vacuum yokugcina yepompo, i-pump stator izocwiliswa emafutheni ukuze izikhala nendawo eyingozi endaweni ngayinye ivame ukugcina uwoyela owanele ukugcwalisa izikhala, ngakho uwoyela udlala indima yokugcoba ngakolunye uhlangothi, kanti ngakolunye uhlangothi, udlala indima ekuvaleni nasekuvimbeni izikhala nendawo eyingozi ukuvimbela ama-molecule egesi ukuthi angaphindeli emuva ngeziteshi ezahlukahlukene aye endaweni enomfutho ophansi.
Umphumela wokuhlanzeka kwephampu yomshini uhlobene nesivinini semoto kanye nokuqina kwebhande, lapho ibhande lemoto likhululekile, ijubane lemoto lihamba kancane kakhulu, umphumela wokuhlanzeka kwephampu yomshini nawo uzoba mubi kakhulu, ngakho-ke kumele siwagcine njalo, siwahlole, umphumela wokuhlanzeka kwephampu yomshini nawo udinga ukuhlola njalo, uwoyela omncane kakhulu, awukwazi ukufinyelela umphumela wokuhlanzeka, iphampu izovuza, uwoyela omningi kakhulu, imbobo yokumunca ivaliwe, ayikwazi ukumunca umoya kanye nokukhipha umoya, ngokuvamile, ezingeni likawoyela elingu-0.5 cm ngaphansi komugqa kungaba.
Iphampu yezimpande enephampu yomshini njengephampu yesiteji sangaphambili
Iphampu yezimpande: Iyiphampu yemishini enezijikelezo ezimbili noma eziningi ezijikelezayo ngesivinini esikhulu. Njengoba isimiso sayo sokusebenza sifana nesomshini womoya iRoots, ingabizwa nangokuthi iphampu ye-Roots vacuum, enesivinini esikhulu sokupompa ebangeni lokucindezela elingu-100-1 Pa. Ilungisa ukushiyeka komthamo wokugeleza onganele wephampu yemishini kuleli banga lokucindezela. Le phampu ayikwazi ukuqala ukusebenza emoyeni, futhi ayikwazi ukukhipha umoya ngqo, indima yayo iwukwandisa umehluko wokucindezela phakathi kwe-inlet kanye ne-exhaust port, okunye kuyadingeka ukuze kuqedwe iphampu yemishini, ngakho-ke, kumele ifakwe iphampu yemishini njengephampu yangaphambi kwesigaba.
Izinyathelo zokuphepha nokugcinwa kwamaphampu omshini
Ngesikhathi sokusetshenziswa kwamaphampu omshini, izinkinga ezilandelayo kumele ziqashelwe.
1, Iphampu yomshini kufanele ifakwe endaweni ehlanzekile neyomile.
2, Iphampu kufanele igcinwe ihlanzekile futhi yomile, uwoyela osephampuni unomphumela wokuvala nokugcoba, ngakho-ke kufanele wengezwe ngokuhambisana nenani elibekiwe.
3, Ukuze ushintshe uwoyela wepompo njalo, lapho ushintsha uwoyela odoti wangaphambilini kufanele ukhishwe kuqala, umjikelezo okungenani izinyanga ezintathu kuya kweziyisithupha ukuze uwushintshe kanye.
4, Landela imiyalelo yokuxhuma ucingo.
5, Iphampu yomshini idinga ukuvala ivalvu yokungenisa umoya ngaphambi kokuyeka ukusebenza, bese icima bese ivula ivalvu yomoya, umoya ungene ephampini ngokusebenzisa i-inlet yokungenisa umoya.
6, Uma iphampu isebenza, izinga lokushisa likawoyela alikwazi ukudlula ku-75℃, ngaphandle kwalokho lizoba lincane kakhulu ngenxa ye-viscosity kawoyela futhi liholele ekuvalekeni okubi.
7, Hlola ukuqina kwebhande lephampu yomshini, isivinini semoto, isivinini semoto yephampu yeRoots, kanye nomphumela wokuvala indandatho yokuvala ngezikhathi ezithile.
–Lesi sihloko sishicilelwe yiGuangdong Zhenhua Technology, umkhiqizi wemishini yokumboza nge-vacuum.
