Iphampu yevacuum - isebenza kanjani iphampu yevacuum ezinjinini zikadizili?

Ngokuvamile amaphampu e-vacuum ahlotshaniswa nezinjini ze-diesel, kodwa kwezinye izimo atholakala nasezinjini zikaphethiloli. Iyini ipompo ye-vacuum? Ngamanye amazwi, iyiphampu ye-vacuum umsebenzi wayo ukudala ingcindezi engalungile. Ukuze usebenze kahle, kubaluleke kakhulu:

• injini;
• uhlelo lwamabhuleki;
• ama-turbocharger;
• UPHONDO.

Bheka izimpawu zezinkinga zephampu futhi ufunde ukuthi ungazilungisa kanjani!

Vacuum - iyini le futha futhi idingeka kuphi?

Kubaluleke kakhulu ukuqonda isimiso sokusebenza kwenjini evuthayo yangaphakathi ngokungenzi lutho. Emayunithi anenjini kaphethiloli, ngokuvamile ayikho i-vacuum, ngoba i-vacuum ku-multiple intake iyakwazi ukukhiqiza amanani adingekayo ukuze kugcinwe i-rpm. Lokhu akusebenzi ezinjinini zedizili ezingenawo amandla. Lapho, ukuthungela ngokungenzi lutho kanye nokusebenza, ngokwesibonelo, uhlelo lwebhuleki kungenzeka ngenxa yepompo ye-vacuum. 

Kungani iphampu ye-vacuum iyingxenye ebalulekile yesistimu?

Isetshenziselwani iphampu yevacuum? Inikeza amanani okuqala we-vacuum ukugcina izingxenye ngazinye zisebenza. Ngaphezu kwalokho, ezinjinini ezinamayunithi ama-injection, i-vacuum nayo inesibopho sokwandisa umfutho kaphethiloli. Ngakho-ke, kulezi zinjini, ukucindezelwa kwepompo ye-vacuum kubonakala kakhulu lapho isiko lomsebenzi liwohloka.

Iphampu ye-vacuum - yenzani?

Ngaphezu kokugcina i-vacuum efanele enjinini ye-vacuum, iphinde ibe nesibopho sokusebenza kwesistimu yamabhuleki ngenkathi ushayela. Ezinjinini zikaphethiloli, ukuqondisa kwamandla kungasebenza kahle ngenxa ye-vacuum edalwe uhlelo lokuthatha. Kudizili, lokhu akwanele. Ngakho-ke, ngenxa yepompo ye-vacuum, kungenzeka ukucindezela i-pedal ye-brake ngaphandle komzamo omkhulu, okuthi, ngaphansi kwethonya le-vacuum, kwandisa ingcindezi izikhathi eziningi. Uma kungenjalo, ungabheka ukuthi yiziphi izimpawu zepompo ye-vacuum engalungile.

Iphampu ye-vacuum - izimpawu zokusebenza kwayo

Uphawu oluvame kakhulu lomonakalo we-vacuum ukuncipha kwamandla okubhuleka. I-turbocharger boost indicator nayo ingahlanya uma ifakwe emotweni. Ekugcineni, ukuwohloka kungabonakala ngokuvuza kwendlu yepompo ngokwayo. Kunjalo, udinga ukwazi ukuthi ubheke kuphi uma kuvuza. Nokho, kaningi, izinkinga zokulawula amabhuleki kanye ne-clutch pedal okwenza kucace ukuthi ivacuum ilindele ukushintshwa noma ukuvuselelwa. Yini okufanele ukhethe ke?

Vacuum futhi ulungise ingcindezi engemihle

Umonakalo ungaqinisekiswa ngokusobala ngokuhlola inani le-vacuum edaliwe. Hlobo luni lwevacuum oludalwa yiphampu yevacuum? Kumamodeli ezimoto ajwayelekile, kufanele asebenze ebangeni ukusuka ku-0,7 kuye ku-0,9 bar. Indlela elula ukuyihlola nge-gauge yokucindezela futhi ekugcineni uqinisekise ukuthi idivayisi iyasebenza. Isizathu esivame kakhulu salesi simo ukuguga noma ukuvuza kwepompo ye-vacuum.

Ukuvuselelwa kwephampu ye-vacuum - kuyafaneleka?

Okuningi kuncike ohlotsheni lomonakalo. Uma uqinisekile ukuthi ipompo ye-vacuum iyavuza, vele uyivale. Kulokhu, kusetshenziswa amakhithi okukhanda akhethekile, angathengwa ezitolo ze-inthanethi nasezitolo zokubhala. Ngokuvamile uzokhokha amashumi ambalwa ama-zloty futhi ukwazi ukuwenza umsebenzi ngokwakho. Kunzima kakhulu lapho isicoci se-vacuum singakuniki isivacu oyifunayo futhi ubona izimpawu ezisobala zomonakalo. Ngemuva kwalokho izodinga ukubuyiselwa endaweni yokugaywa kabusha.

Inketho yokugcina (ebiza kakhulu) ukuthenga into entsha. Kodwa-ke, izintengo zezingxenye ezinjalo ngokuvamile ziphakeme ngokuphindwe ka-3 kunalezo ezigaywe kabusha.

I-Vacuum - yini ethinta impilo yesevisi yepompo yenjini?

Ngokwenza i-vacuum, ipompo ye-vacuum ikhiqiza ukushisa, ngakho-ke kufanele ipholiswe ngamafutha enjini. Lesi yisona sizathu esikhulu sokwehluleka kwakhe. Ukungcola okuntanta emafutheni kanye nezinga lawo eliphansi kungabangela ukuba iphampu ibambe. Kungakho kufanelekile ukugxila emafutheni ekhwalithi enhle kakhulu futhi unakekele ukushintshwa okuvamile ngemvamisa enconyelwe injini. Isimo se-solenoid diaphragms ku-EGR siphinde sithinte isimo se-vacuum, ngoba siqondisa i-vacuum kule element futhi. Izinto ezingcolisayo zingena empompini yevacuum futhi zingayicekela phansi.

Kudingeka iphampu yevacuum ezinjinini zikadizili. Uzoyizwa ilimele ngemva kokusebenzisa iyunithi, ukubhuleka kabi, noma ukuvuza kukawoyela namafutha. Uphawu ngokuvamile luyisixazululo, kodwa uma izakhi zephampu zibambekile, iphampu ingase idinge ukushintshwa. Futhi lezi zindleko zingaphezu kwama-euro ayi-100, ngakho-ke kungcono ukunakekela iyunithi. Lapho ushintsha uwoyela, qondiswa izinga lomkhiqizo. Ngale ndlela, uzophinde unakekele isimo sepompo ye-vacuum, egcotshwe ngala mafutha. Kuyafaneleka futhi ukuthi kubhekwe ukuthi kukhona yini okungaba yinkungu futhi ubone ukuthi akukho yini ukuvuza emshinini.
