Uma uhlanganisa i-iphampu encane ye-vacuumUma isetshenziswa kudivayisi yezokwelapha, ithuluzi lelebhu, noma ukusetshenziswa kwezimboni, omunye wemibuzo ebaluleke kakhulu uthi: "Ingadonsa i-vacuum enamandla kangakanani ngempela?" Ngokukhethekile, nge-iphampu yokuhlanza i-diaphragm, impendulo ichazwa yingcindezi yayo yokugcina, incazelo eyisihluthulelo enquma ukufaneleka kwayo kuphrojekthi yakho.

Lesi sihloko sichaza izici ezithinta izinga le-vacuum lala maphampu nokuthi yini ongayilindela ngempela.

Iyini i-Diaphragm Vacuum Pump?

Aiphampu yokuhlanza i-diaphragmuhlobo lwephampu yokuhambisa umoya enhle esebenzisa i-diaphragm e-elastomeric eguquguqukayo, ama-valve okuhlola, kanye negumbi ukudala i-vacuum. Ukusebenza kwazo okungenawo uwoyela nokomile kuzenza zilungele ukusetshenziswa lapho ukuhlanzeka nokuphatheka kalula kubaluleke kakhulu.

Ububanzi Obujwayelekile Be-Vacuum Yamaphampu Amancane E-Diaphragm

Nakuba amakhono ehluka ngokwemodeli kanye nekhwalithi, amayunithi amaningi amancane ephampu ye-vacuum yohlobo lwe-diaphragm afinyelela i-vacuum ephezulu (ingcindezi ephansi kakhulu angafinyelela kuyo) kulolu hlu olulandelayo:

Amasentimitha angu-15 kuya kwangu-29.9 e-Mercury (inHg) noma i-Torr engu-50 kuya ku-760 noma i-gauge engu--7 kuya ku-100 kPa.

• I-Lower End (Inhloso Ejwayelekile): ~15-20 inHg (-50 kuya ku-67 kPa). Ivame kakhulu kumaphampu ashibhile ezicelo ezifana nokuhlola umoya, ukumunca okulula, noma ukubamba.

• Isigaba Esiphezulu (Ibanga Lezokwelapha Nelebhu): ~22-29.9 inHg (-75 kuya ku-100 kPa). Lawa amaphampu asebenza kahle kakhulu asetshenziswa ezindleleni ezidinga kakhulu njengokuhlaziywa kwegazi, ukuhlunga, kanye nemishini yokuxilonga ezenzakalelayo.

Ngomongo:

• Ukucindezela Komoya: 0 inHg (igeyiji) noma 101.3 kPa (ngokuphelele)

• I-Vacuum Ephelele: 29.92 inHg (igeyiji) noma -101.3 kPa (igeyiji)

Lokhu kusho ikhwalithi ephezuluiphampu yokuhlanza i-diaphragmingasusa cishe u-95-99% womoya kuvolumu evaliwe.

Izici Eziyinhloko Ezinciphisa Ukuthi Iphampu Ye-Diaphragm Ingahamba Kanjani Ngaphansi

Izici eziningana zokuklama ezingokwemvelo zivimbela iphampu ye-diaphragm ukuthi ingafinyeleli ku-vacuum ephelele:

1. Ukusebenza Kahle Komthamo kanye "Nomthamo Ofile": Ayikho iphampu engasusa ngokuphelele wonke umoya egumbini lokucindezela. Inani elincane legesi elisele, elaziwa ngokuthi "umthamo ofile," lihlala livalelekile ngemva kokushaya ngakunye futhi liyanwetshwa kabusha, okunciphisa ingcindezi ephansi kakhulu engafinyeleleka.

2. Ukuvuza Kwesivalo Nokuvuza Kwevalvu: Ukuvuza kwe-microscopic okudlule isivalo se-diaphragm noma amavalvu okuhlola kungavumela umoya ukuthi ungene emuva ohlangothini lwe-vacuum. Amaphampu ekhwalithi ephezulu asebenzisa izingxenye ezisebenza ngomshini onembile kanye nezinto ezisezingeni eliphezulu ukunciphisa lokhu.

3. Ukukhipha Igesi Ezintweni Ezithile: Ngaphansi kwe-vacuum, izinto ezithile (njengezinye ipulasitiki noma irabha) zingakhipha amagesi noma umusi ovalelekile ngaphakathi kwesakhiwo sazo. Lesi simo, esibizwa ngokuthi i-outgassing, sinegalelo ekucindezelekeni ngaphakathi kwesistimu futhi sakha phansi iphampu engenakukunqoba.

4. Ukuguquguquka kwe-diaphragm kanye nokuvala: Ukuguquguquka kwe-diaphragm ngokwayo kunciphisa isilinganiso sokucindezela. I-diaphragm eqinile ingadala i-vacuum enamandla kodwa ingadinga injini enamandla kakhulu futhi inezindlela ezahlukene zokushintshana isikhathi eside.

Izicelo ze-Vacuum Strength

• I-Vacuum Ephansi (15-20 inHg / -50 kuya ku-67 kPa): Izinkomishi zokumunca zokubamba, ukusebenza okulula komoya, izikhwama zokuthatha amasampula omoya, amadivayisi okumunca ayisisekelo.

• I-Vacuum Ephakathi (20-25 inHg / -67 kuya ku-85 kPa): Ukumunca kwezokwelapha, ukuqapha umfutho wegazi, amaphampu amabele, ukuphathwa koketshezi okuzenzakalelayo, imishini yokupakisha.

• I-Vacuum Ephakeme/Ejulile (25-29.9 inHg / -85 kuya ku-100 kPa): Ukuhlunga kwelabhorethri, ukukhipha igesi nge-vacuum, ukuphathwa kwe-semiconductor, amathuluzi okuxilonga athuthukisiwe.

Indlela Yokukhetha Iphampu Efanele Izidingo Zakho Zokuhlanza I-Vacuum

1. Hlola Ishidi Lokucaciswa: Njalo funa isilinganiso se-"Ultimate Vacuum" noma se-"Final Vacuum", esilinganiswa nge-inHg, kPa, noma i-Torr. Lena ingcindezi ephansi kakhulu yephampu.

2. Cabanga Ngezinga Lokugeleza: Iphampu ingase ithole i-vacuum ejulile, kodwa uma inezinga eliphansi lokugeleza (i-CFM noma i-LPM), kuzothatha isikhathi eside kakhulu ukufika lapho. Ngokuvamile udinga ukulinganisela i-vacuum yokugcina nesivinini.

3. Qonda Izidingo Zesistimu Yakho: Iphampu kumele ibe namandla ngokwanele ukunqoba noma yikuphi ukuvuza ohlelweni lwakho futhi ikwazi ukufeza ingcindezi yokusebenza edingekayo yesicelo sakho.

4. Beka Ikhwalithi Ebalulekile: Ngezicelo ezibalulekile, tshala imali kuphampu evela kumkhiqizi odumile osebenzisa ama-valve nezivalo zekhwalithi ephezulu ukuqinisekisa ukuthi ihlangabezana njalo nokusebenza kwayo okulinganiselwe kwe-vacuum.

Isiphetho

Ngakho-ke, i-a ingaba ngaphansi kangakananiiphampu encane ye-diaphragm cleanerhamba? Nakuba ingenakukwazi ukufeza i-vacuum ephezulu yamaphampu amakhulu e-rotary vane avaliwe ngowoyela, iphampu ye-vacuum ye-diaphragm esezingeni eliphezulu inamandla kakhulu, ifinyelela amazinga e-vacuum aphansi njengo-29 inHg (-98 kPa). Lokhu kuyenza ibe yisisombululo esinamandla, esihlanzekile, nesithembekile sezinhlelo eziningi zezokwelapha, zezimboni, nezelebhu. Uma ukhetha iphampu, qondanisa ngokucophelela imininingwane yayo yokugcina ye-vacuum kanye nezinga lokugeleza nezidingo zesistimu yakho ukuqinisekisa ukusebenza kahle.
