Ngamanye amaxesha, ukuqalisa injini, kufuneka ugcwalise kwangaphambili inkqubo yokunikezelwa kwamandla ngepetroli - lo msebenzi uxazululwa ngokusebenzisa impompo ye-booster manual.Funda malunga nokuba yintoni impompo ye-fuel manual, kutheni ifuneka, zeziphi iintlobo kunye nendlela esebenza ngayo, kunye nokukhetha kunye nokutshintshwa kwezi zixhobo, funda inqaku.
Yintoni impompo yamafutha eyenziwa ngesandla?
Impompo yokumpompa i-fuel manual (ipompo ye-fuel manual, impompo ye-fuel) yinto yesistim ye-fuel system (inkqubo yamandla) yeenjini zokutsha zangaphakathi, i-low-capacity pump kunye ne-manual drive yokupompa inkqubo.
Ipompo ye-fuel manual isetyenziselwa ukugcwalisa imigca kunye namacandelo enkqubo ye-fuel ngaphambi kokuba iqalise injini emva kwexesha elide lokungasebenzi, emva kokutshintsha izihluzo zepetroli okanye ukwenza ezinye izilungiso ngexesha apho i-fuel resses ikhutshwe.Ngokuqhelekileyo, izixhobo ezineenjini zedizili zixhotyiswe ngeempompo ezinjalo, aziqhelekanga kakhulu kwiinjini zepetroli (kwaye, ngokukodwa, kwiinjini ze-carburetor).
Iintlobo zeempompo zokunyusa amafutha
Iimpompo ze-fuel manual zihlulwe zibe ngamaqela amaninzi ngokomgaqo wokusebenza, uhlobo kunye noyilo lokuqhuba, kunye nendlela yokufakela.
Ngokomgaqo wokusebenza, iimpompo zokudlulisa ngesandla zizinto ezintathu eziphambili:
• I-Membrane (diaphragm) - ingaba ne-membrane enye okanye ezimbini;
• Imvubu;
• Ipiston.
Iimpompo zinokuxhotyiswa ngeentlobo ezimbini zokuqhuba:
• Incwadana;
• Idityanisiwe - umbane okanye oomatshini abavela kwi-injini kunye nencwadana.
Kuphela ziidrive zezandla ezineempompo ze-bellows kunye nobuninzi beempompo ze-diaphragm zezandla.Iimpompo zepiston zihlala zine-drive edibeneyo, okanye zidibanise iimpompo ezimbini ezihlukeneyo kwindlu enye - kunye ne-mechanical and manual drive.Ngokubanzi, iiyunithi ezine-drive edibeneyo azikho iimpompo ze-manual - ziyi-fuel (kwii-injini ze-petroli) okanye i-fuel priming (kwii-injini ze-diesel) iimpompo ezikwazi ukwenza ukupompa ngesandla.
Ngokoyilo lokuqhuba, iimpompo zediaphragm kunye nepiston zezi:
• Nge-lever drive;
• Ngokucofa-iqhosha lokuqhuba.
Ipompo yepetroli ye-diaphragm kunye nedrive edibeneyo
Kwiimpompo zohlobo lokuqala, i-lever eguqukayo isetyenzisiweyo, kwiiyunithi zodidi lwesibini - isibambo ngendlela yeqhosha elinomthombo wokubuya.Kwiimpompo ze-bellows, akukho kuqhuba njengoko kunjalo, lo msebenzi wenziwa ngumzimba wesixhobo ngokwawo.
Okokugqibela, iimpompo zezandla zinokuba nofakelo olwahlukileyo:
• Ekugqabhukeni komzila wamafutha;
• Ngqo kwisihluzo samafutha;
• Kwiindawo ezohlukeneyo ezikufutshane nezinto zesixokelelwano sesibaso (kufuphi netanki yamafutha, ecaleni kwenjini).
Iimpompo zokukhanya kunye ne-compact bellows ("iipere") zingeniswa kumgca wepetroli, azinakho ukufakela okuqinileyo kwi-injini, umzimba okanye ezinye iindawo.Iipompo ze-diaphragm ezine-push-button drive ("amasele"), ezenziwe ngendlela yeyunithi edibeneyo, zifakwe kwiifilitha zepetroli.I-piston kunye neepompo ze-diaphragm ezine-lever kunye ne-drive edibeneyo zinokufakwa kwi-injini, amalungu omzimba, njl.
Uyilo kunye nomgaqo wokusebenza kweempompo zezandla zamafutha
Ukuhanjiswa kweempompo ze-diaphragm kunye ne-bellows kubangelwa ukulula koyilo lwazo, ixabiso eliphantsi kunye nokuthembeka.Eyona nto ingalunganga kwezi yunithi kukusebenza okuphantsi, kodwa kwiimeko ezininzi kungaphezulu kokwaneleyo ukumpompa inkqubo yamafutha kwaye uqalise ngempumelelo injini.
Iimpompo zamafutha okwenziwa ngesandla zohlobo lwe-bellows ("amapere")
Iimpompo zeBellows zezona zicwangciswe ngokulula.Zisekelwe kumzimba we-elastic ngendlela yebhalbhu yerabha okanye i-cylinder yeplastiki edibeneyo, kuzo zombini iziphelo kukho i-valve - i-intake (i-suction) kunye ne-exhaust (i-discharge) enezixhobo zabo zokudibanisa.Iivalvu zivumela ulwelo ukuba ludlule kwicala elinye kuphela, kwaye i-elastic housing yimpompo yokuqhuba.Iivalvu zezona zilula zebhola.
Ipompo yesandla yohlobo lwe-Bellows isebenza ngokulula.Ukunyanzeliswa komzimba ngesandla kukhokelela ekunyukeni koxinzelelo - phantsi kwempembelelo yolu xinzelelo, i-valve yokukhupha ivula (kunye ne-valve yokungena ihlala ivaliwe), umoya okanye i-fuel ngaphakathi iqhutywe kumgca.Emva koko umzimba, ngenxa ye-elasticity yawo, ubuyela kwisimo sawo sokuqala (ukwandisa), uxinzelelo olukuyo luyehla kwaye lube ngaphantsi kwe-atmospheric, i-valve yokukhupha ivala, kwaye i-valve yokungena ivula.I-fuel ingena kwimpompo nge-valve yokungena evulekileyo, kwaye ngexesha elizayo xa umzimba ucinezelekile, umjikelezo uphinda.
Iimpompo ze-diaphragm zintsonkothe ngakumbi.Isiseko seyunithi yintsimbi yensimbi enecavithi ejikelezayo, evalwe ngesivalo.Phakathi komzimba kunye nesimbozo kukho i-diaphragm elastic (i-diaphragm), exhunywe ngentonga kwi-lever okanye iqhosha kwi-cover cover.Emacaleni ombhobho kukho i-valve yokungena kunye ne-outlet yoyilo okanye enye (kwakhona, njengomthetho, ibhola).
Ukusebenza kwempompo ye-diaphragm kufana naleyo yeeyunithi ze-bellows.Ngenxa yamandla asetyenziswe kwi-lever okanye iqhosha, i-membrane iphakama kwaye iwa, ikhula kwaye iyancipha umthamo wegumbi.Ngokunyuka komthamo, uxinzelelo lwegumbi luba ngaphantsi kune-atmospheric, obangela ukuba i-valve yokungena ivuleke - i-fuel ingena kwigumbi.Ngokuhla kwevolumu, uxinzelelo lwegumbi luyanda, i-valve yokungena ivala, kwaye i-valve yokukhupha ivula - i-fuel ingena kumgca.Emva koko inkqubo iphinda iphindwe.
Umgaqo wokuSebenza wePump yeDiaphragm
Iimpompo ze-diaphragm zintsonkothe ngakumbi.Isiseko seyunithi yintsimbi yensimbi enecavithi ejikelezayo, evalwe ngesivalo.Phakathi komzimba kunye nesimbozo kukho i-diaphragm elastic (i-diaphragm), exhunywe ngentonga kwi-lever okanye iqhosha kwi-cover cover.Emacaleni ombhobho kukho i-valve yokungena kunye ne-outlet yoyilo okanye enye (kwakhona, njengomthetho, ibhola).
Ukusebenza kwempompo ye-diaphragm kufana naleyo yeeyunithi ze-bellows.Ngenxa yamandla asetyenziswe kwi-lever okanye iqhosha, i-membrane iphakama kwaye iwa, ikhula kwaye iyancipha umthamo wegumbi.Ngokunyuka komthamo, uxinzelelo lwegumbi luba ngaphantsi kune-atmospheric, obangela ukuba i-valve yokungena ivuleke - i-fuel ingena kwigumbi.Ngokuhla kwevolumu, uxinzelelo lwegumbi luyanda, i-valve yokungena ivala, kwaye i-valve yokukhupha ivula - i-fuel ingena kumgca.Emva koko inkqubo iphinda iphindwe.
