Uma usebenza ne-iphampu encane ye-vacuum, aiphampu yokuhlanza i-diaphragm, noma iphampu encane ye-vacuum engu-12 volt, lo ngumbuzo oyisisekelo okufanele uwuqonde: ingabe iyandisa noma yehlisa ingcindezi? Impendulo emfushane ithi: Iphampu ye-vacuum yehlisa ingcindezi. Isusa ngenkuthalo ama-molecule egesi (njengomoya) kuvolumu evaliwe ukuze idale indawo enomfutho ophansi, noma i-vacuum.

Lesi sihloko sizochaza isayensi engemuva kokusebenza kwala maphampu, indima yokucindezela, nokuthi kungani lesi simiso sibalulekile ekusetshenzisweni kwakho.

Ukuqonda Ingcindezi: Izisekelo

Ezingeni lolwandle, siphila ngaphansi kongqimba lomoya olunengcindezi—cishe amakhilogremu angu-14.7 nge-intshi yesikwele (PSI) noma amakhilopascal angu-101.3 (kPa). Lokhu kuyingcindezi yomoya. Umsebenzi wephampu ye-vacuum ukwehlisa ingcindezi ngaphakathi kwegumbi elivaliwe ngaphansi kwaleli zinga lomoya.

• Ukunciphisa Ukucindezela (Ukudala I-Vacuum): Ukususa ama-molecule esikhaleni kusho ukushayisana okuncane nezindonga zesitsha. Leli nani eliphansi lokushayisana liholela ekucindezelekeni okuphansi.

• Ukwandisa Ukucindezela (Ukucindezela): Ukwengeza ama-molecule engeziwe noma ukuwacindezela endaweni encane kwandisa inani lokushayisana ngaleyo ndlela kwandisa ukucindezela. Lona umsebenzi we-compressor noma iphampu yomoya.

Indlela Iphampu Yokupompa I-Diaphragm Enciphisa Ngayo Ukucindezela

Iphampu ye-vacuum ye-diaphragm iyisibonelo esiphelele sokubonisa lokhu. Luhlobo lwephampu yokufuduka enhle. Nansi indlela esebenza ngayoukwehlaingcindezi:

1. I-Intake Stroke: Injini ishukumisa i-diaphragm ukuze yandise ivolumu yegumbi lephampu. Lokhu kwanda kudala indawo enomfutho ophansi ngaphakathi kwegumbi.

2. Ukumunca: Umfutho womoya ophezulu wangaphandle uphoqa umoya ohlelweni lwakho oluxhunyiwe (isb., isikhwama esivaliwe noma ikamelo) ungene ekamelweni lepompo elinomfutho ophansi ngevalvu yokungena. Lena yipompoukumuncaphuma umoya.

3. Ukushaya Komoya Ophumayo: I-diaphragm ibuyela emuva, yehlisa ivolumu yegumbi futhi icindezela umoya ovalelekile.

4. Ukuxoshwa: Ingcindezi ephezulu manje ngaphakathi kwegumbi iphoqa ivalvu yokuphuma ukuthi ivuleke, bese umoya uphushelwa ngaphandle emoyeni.

Lo mjikelezo uphinda izikhathi eziningi ngomzuzwana, ngokuqhubekayoukususaama-molecule omoya avela ohlelweni lwakho ngaleyo ndlela ehlisa ingcindezi yangaphakathi.

Indima Yephampu Yokusula I-Vacuum Engama-volt angu-12

Iphampu ye-vacuum engu-12 volt, ngokuvamile i-iphampu encane ye-diaphragm, isebenza ngale ndlela efanayo. Ubukhulu bayo obuncane kanye nekhono lokusebenza emthonjeni wamandla we-DC ojwayelekile (njengebhethri yemoto noma ugesi) kwenza kube kuhle kakhulu ezinhlelweni zokusebenza eziphathwayo noma ezifakiwe laphoukucindezela okunciphisayokuyadingeka, njengokuthi:

• Amadivayisi Ezokwelapha: Ukususa umoya ukuze kudalwe ukumunca kwamanzi noma amathuluzi okuhlinzwa.

• Ukupakishwa Kokudla: Ukukhipha umoya ezikhwameni ukuze kulondolozwe ubusha (ukuvalwa kwe-vacuum).

• Izimoto: Ukusiza ama-brake booster noma ukulawula izinhlelo zokukhishwa komoya.

• Ukukhiqiza Izinto Zogesi: Ukubamba izingxenye endaweni yazo ngezinkomishi zokumunca i-vacuum.

Imininingwane Eyinhloko: Ukulinganisa Ukuncipha Kokucindezela

Uma ukhetha iphampu encane ye-vacuum, uzobona imininingwane echaza ikhono layo lokwenza kanjalo.yehlisa ingcindezi:

• I-Ultimate Vacuum: Ingcindezi ephansi kakhulu ipompo engayithola, elinganiswa ngamasentimitha e-Mercury (inHg), kPa, noma i-Torr. Inani eliphezulu le-inHg lisho i-vacuum enamandla (isb., i-20 inHg iwukwehla kwengcindezi okukhulu kune-15 inHg).

• Izinga Lokugeleza (i-CFM noma i-LPM): Ukuthi iphampu ingawususa ngokushesha kangakanani umoya. Izinga lokugeleza eliphezulu lizokwenzayehlisa ingcindezingokushesha ngevolumu enkulu.

Isiphetho: Konke Kumayelana Nokususwa

Ukuze kucace ngokuphelele: umsebenzi wephampu yokufutha i-vacuum ukunciphisa ingcindezi ngokususa ama-molecule egesi ohlelweni oluvaliwe. Kungakhathaliseki ukuthi iyiyunithi enamandla yezimboni noma iphampu yokufutha i-vacuum encane engu-12 volt yephrojekthi ye-DIY, isimiso sesayensi esiyinhloko sihlala sifana. Ukuqonda lokhu kukusiza ukuthi ukhethe iphampu efanele—njengephampu yokufutha i-diaphragm esebenza kahle—ngokusekelwe ekutheni udinga kangakanani ingcindezi yehliswe nokuthi uyidinga ngokushesha kangakanani isicelo sakho esithile.
