Kuyunithi yepompo ye-vacuum ehlanganisa ipompo yeRoots kanye nepompo ye-rotary vane, ukukhetha isihlungi esifanele kubalulekile ekuzinzeni kwesistimu kanye nokuvikelwa ekungcoleni kwezinhlayiya. Kodwa-ke, iphutha elivamile ukwengeza amazinga okugeleza kwamaphampu womabili noma ukusebenzisa izinga lokugeleza kwephampu eyinhloko (Roots) njengesici esiyinhloko sazo zonke izihlungi. Le ndlela "efanelana nosayizi owodwa" ivame ukuholela ekusebenzeni kahle kokuhlunga okungekuhle, isivinini sokupompa esincishisiwe, ngisho nomonakalo wemishini.
I-logic efanele yokukhetha ilandela isimiso "sokucushwa okuhlukile ngephampu ngayinye, ukufanisa ngokwesidingo," kanye nesu lokuvumelana elisetshenziswa ngqo ekukhetheni isihlungi sokungena.
1. Isilinganiso Sezinga Lokugeleza: I-Rotary Vane Pump njenge-Lower Limit, i-Roots Pump Connection njenge-Dominant Factor
Ngokwethiyori, izinga lokugeleza kwesihlungi kufanele lisekelwe esivinini sokupompa sephampu ye-rotary vane. Kodwa-ke, ngenxa yokuthi isihlungi sokungena sifakwa ngqo echwebeni lokungena lephampu yeRoots, isihlungi esincane kakhulu esifanelana ncamashi nokufuduka kwephampu ye-rotary vane asinakusetshenziswa. Isizathu ukuthi ichweba lokungena lephampu yeRoots likhulu kakhulu kunechweba lokukhipha lephampu ye-rotary vane. Ukukhetha isihlungi ngokusekelwe ngokuqinile esilinganisweni esincane sokugeleza kungaholela ekuxhumekeni okuncane okungenakukwazi ukuhambisana ne-flange enkulu yobubanzi bephampu yeRoots (isb., DN100 noma DN160). Ukuphoqa uxhumano olunjalo ngezinciphisi kungadala ukumelana okukhulu kokugeleza, kunciphise kakhulu ukusebenza kahle kokungena kwephampu yeRoots noma kuvimbele ngisho nokuqala kwayo.
Ngakho-ke, isu elifanele lokuvumelana yileli: Thatha isivinini sokupompa esiqhubekayo sepompo ye-rotary vane njengomkhawulo wokugeleza ophansi, ngenkathi usebenzisa usayizi wokuxhuma wephothi lokungena lepompo yeRoots njengenqubo yokukhetha evelele. Empeleni, kufanele ukhethe isihlungi esixhuma ngqo i-flange yepompo yeRoots (edinga cha noma i-reducer emfushane kakhulu), futhi esinesilinganiso sokugeleza esilinganiselwe esiseduze ngangokunokwenzeka nesivinini sokupompa sepompo ye-rotary vane vane. Uma kuvela ingxabano, beka phambili ukuhambisana kokuxhumeka, uvumele ukugeleza okulinganiselwe kwesihlungi kube kukhulu ngokulingene kunesivinini sepompo ye-rotary vane vane. Le ndlela "yokuxhuma kuqala, yokuyekethisa ukugeleza" ivikela ipompo yeRoots ngokunemba okwanele ngaphandle kokuphazamisa ukusebenza kokupompa kweyunithi ngokudambisa ngokweqile.
2. Ukukhetha Isihlungi Sokungena: Ukulinganisela Ukunemba Nokuxhumeka
Ukunemba Kwesihlungi: Kungakhathaliseki ukuthi ukugeleza kungakanani, ukunemba kwesihlungi sesihlungi sokungena kumele kukhethwe ngokuqinile ngokwezidingo zephampu yeRoots (ngokuvamile i-1-3μm) ukuze ibambe uthuli olulingana ne-micron futhi ivikele ama-rotor ayo anembile. Ukuvuleka kwe-rotor kuphampu yeRoots kuncane kakhulu, okwenza kube nomuzwa omkhulu ezinhlayiyeni. Lesi sidingo asishintshi ngokulungiswa kwesilinganiso sokugeleza noma usayizi wokuxhuma.
Ukufaniswa Koxhumano: Usayizi woxhumano kumele ufane nembobo yokungena yepompo yeRoots. Ngokuvamile, amapompo eRoots aneziphazamiso ezinkulu ze-vacuum ezifana nezindinganiso ze-KF, ISO, noma ze-DN (isb., DN100, DN160). Lesi yisithiyo esiyinhloko enqubweni yokukhetha.
3. Ukukhetha Isihlungi Sokukhipha Umoya: Isihluthulelo Sokwelashwa Ngemva Kokwelashwa
Isihlungi sokukhipha umoya sivame ukufakwa echwebeni lokukhipha umoya lephampu ye-rotary vane. Umsebenzi waso oyinhloko ukuhlukanisa inkungu kawoyela, okuvumela ukukhishwa kwegesi okunobungani nemvelo noma ukubuyiswa kukawoyela.
Ukugeleza Nokuxhumana: Akukho ukuvumelana okudingekayo lapha. Ukukhetha kumele kulandele ngokuqinile ukugeleza kokukhipha kwephampu ye-rotary vane kanye nosayizi wokuxhuma. Imbobo yokukhipha yephampu ye-rotary vane vane ngokuvamile iwuxhumano olunezintambo ezincane (isb., G3/4″, G1″). Isihlungi sokukhipha sixhuma ngqo kulembobo.
Ukucatshangelwa Kokusebenza: Njengoba amaphampu e-rotary vane ephethe inkungu enkulu kawoyela emhubheni wawo wokukhipha ugesi, isihlungi kufanele sibe nomsebenzi wokuhlanganisa ophumelelayo (ukusebenza kahle ≥99.9%). Kunconywa futhi ukusihlomisa ngomugqa wokubuyisela uwoyela ukuze uqondise uwoyela ohlungiwe emuva ephampeni ukuze uphinde usetshenziswe, kuncishiswe izindleko zokulungisa.
Lahla umqondo olula wokuhlanganiswa kokugeleza. Thatha ipompo ye-rotary vane—ipompo ekhipha igesi ngempela—njengomkhawulo wokugeleza ophansi, ngenkathi usebenzisa uxhumano olukhulu lwepompo yeRoots njengombandela wokukhetha oyinhloko. Le ndlela ifinyelela ibhalansi efanele phakathi kokuvikelwa nokusebenza.
