Ekukhiqizweni kwezimboni nasekukhiqizweni kwezimoto, ubuchwepheshe bokuvala bubalulekile ekuqinisekiseni ukusebenza okuthembekile kwemishini. Muva nje, uphawu oluxhumanisa kabili olunomklamo omusha kanye nokusebenza okuhle kakhulu lungene emakethe, lunikeza imboni ikhambi elisha lokuvala futhi luvuse ukunaka okubanzi. Ngesikhathi esifanayo, isithombe esinemininingwane esibonisa injini nezingxenye zayo sisabalaliswe kabanzi ku-inthanethi, okuthuthukisa ukuqonda kwabantu ngesakhiwo senjini kanye nokusetshenziswa kwezingxenye zokuvala.
1. Ukubukeka Komkhiqizo Nezakhiwo Zezinto Ezibalulekile
Isivalo esinama-double-connector siqukethe amasongo amabili erabha axhunyiwe: uhlangothi olulodwa luyindandatho yesikwele, kanti olunye uhlangothi luyindandatho enkulu e-elliptical enechashazi elincane ekugcineni. Lo mklamo awugcini nje ngokufeza ukusungula izinto ezintsha kodwa futhi ucabangela ngokugcwele izidingo zokusebenza ezimweni zokufakwa kwangempela kanye nokusetshenziswa. Wenziwe ngerabha yekhwalithi ephezulu futhi ucutshungulwa ngobuchwepheshe obuthuthukisiwe be-vulcanization. Izinto zerabha ngokwazo zinokunwebeka okuhle kakhulu, ukumelana nokuguguleka, kanye nokumelana nokugqwala. Inqubo ye-vulcanization ithuthukisa kakhulu isakhiwo sayo sama-molecule, iqinisekisa ukuthi igcina izakhiwo zomzimba ezizinzile ngaphakathi kobubanzi bokushisa obuphakathi kuka-40°C no-150°C nasezindaweni ezicindezelwe kakhulu, eziyinkimbinkimbi ngamakhemikhali, ivimbela ngempumelelo ukuguga, ukuguquguquka, nezinye izinkinga, iqinisekisa ukusebenza kokuvala okuhlala isikhathi eside.
2. Imisebenzi Eyinhloko kanye Nezinkambu Zokusebenza
(a) Ukusebenza Okumangalisayo Kokuvala
Kokubili imishini yemishini neyezimoto, ukuvuza koketshezi kuyisici esibalulekile esithinta ukusebenza okuvamile. Ngenxa yesimo sayo esiyingqayizivele kanye nezinto zerabha zekhwalithi ephezulu, uphawu lwezixhumi ezimbili lungagcwalisa izikhala ezincane phakathi kwezingxenye, lwakha isithiyo sokuvala esithembekile. Isibonelo, ezinjinini zezimoto, kudingeka i-gasket yekhanda lesilinda phakathi kwekhanda lesilinda kanye nebhulokhi yesilinda ukuvimbela ukuvuza kwe-coolant kanye namafutha enjini. Ingxenye yesikwele yesixhumi esinama-dual seal ingazivumelanisa ngokunembile nezixhumi ezifanayo, ivimbele ukuvuza kwe-oyili kanye ne-coolant nokuxubana, iqinisekise ukusebenza okuzinzile kwenjini ngaphansi kokushisa okuphezulu, ukucindezela okuphezulu, nokudlidliza, igcine ukuthambisa okuhle kanye nemiphumela yokupholisa, futhi yandise impilo yenjini. Ezinhlelweni ze-hydraulic zemishini yemishini, ingxenye yendandatho ye-elliptical ifanelana kahle nezingxenye ezixhumanisayo zamasilinda e-hydraulic namaphampu, igcina ukuvala ngaphansi komthelela we-oyili we-high-pressure ngenxa yamandla ayo amahle kakhulu okuguquguquka kwe-elastic, iqinisekisa ukusebenza kahle kwezinhlelo ze-hydraulic kanye nokuthuthukisa ukusebenza kwemishini kanye nokunemba kokusebenza.
(b) Umsebenzi Wokuxhuma Nokulungisa
Isakhiwo esinezindandatho ezimbili se-dual-connector seal sinikeza kokubili imisebenzi yokuvala kanye nokuxhuma. Ekuhlanganisweni kwezingxenye zezimoto, njengokuxhumana phakathi kwe-input manifold kanye ne-engine block, i-seal ifakwa endaweni yokuxhumana, hhayi nje kuphela ukunikeza ukuvala ukuvimbela ukuvuza kodwa futhi nokuthuthukisa ukuqina kokuxhumeka ngokuguquguquka kwe-elastic kanye nezici zesakhiwo, kunciphisa ingozi yokwehluleka okubangelwa ukukhululeka. Ezinhlelweni zamapayipi ezimboni, yenza lula inqubo yokuxhuma ipayipi, ithathe indawo yezindlela zokuxhuma zendabuko eziyinkimbinkimbi ze-bolt kanye ne-nut, ivumela ukuvalwa okusheshayo kwepayipi, inciphise izingozi zokuvuza, yehlise izindleko zokulungisa kanye nobunzima, futhi ithuthukise ukusebenza kahle kokuthutha izinto kanye nokuphepha.
3. Izinzuzo Ezibalulekile Zokusebenza
(a) Ukuzivumelanisa Nezinga Lokushisa Elibanzi
Imishini yezimboni kanye nobuchwepheshe bezimoto bavame ukubhekana nezimo zokushisa ezibucayi kakhulu. Izinto zerabha zesivalo esixhumanisayo ezimbili zakhiwe ngokukhethekile ukuze kugcinwe ukusebenza okuzinzile kanye nokusebenza kahle kokuvala ngaphakathi kwezinga lokushisa eliphakathi kuka-40°C no-150°C. Ebusika obubandayo, ingabuyisa ngokushesha ukuqina kwayo ukuqinisekisa ukugcotshwa okuvamile kwezinjini zezimoto, kuyilapho ezindaweni zokushisa okuphezulu, ayithambisi noma ayiguquguquki, ivikela njalo izingxenye zangaphakathi kanye noketshezi.
(b) Ukumelana Nokuguguleka Okukhulu Nokumelana Nokuguga
Ukunyakaza njalo kwemishini kanye nokusebenza kwemoto isikhathi eside okunezivalo ezihambisana nokungqubuzana okuqhubekayo kanye nokucindezeleka komshini. I-seal enezixhumi ezimbili isebenzisa izinto zerabha zekhwalithi ephezulu enokwelashwa okukhethekile kobuso ukunciphisa ukungqubuzana, okubangela ukuguguleka okuhamba kancane. Ngaphezu kwalokho, izithasiselo zokulwa nokuguga ezifakwe ku-seal zimelana ngempumelelo nemiphumela yemisebe ye-UV, i-ozone, nezinye izici zemvelo. Ngisho nangemva kokunyakaza okuyinkimbinkimbi komshini isikhathi eside, igcina ukuqina okuhle kanye nokusebenza kokuvala, inciphisa imvamisa yokugcinwa nokufakwa kwemishini, yehlisa izindleko zokusebenza, futhi ithuthukise ukusebenza kahle kokukhiqiza.
(c) Ukumelana Okubanzi Kwamakhemikhali
Ekukhiqizweni kwezimboni nasekusebenzeni kwezimoto, izivalo zivezwa kuma-chemical agents ahlukahlukene. Izinto zerabha zesivalo esixhumanisa kabili zenzelwe ukumelana kahle noketshezi oluvamile lwezimoto, uwoyela we-hydraulic wezimboni, amafutha okugcoba, nezinye izinto. Azishintshi kakhulu ngokomzimba noma ngamakhemikhali ngisho nangemva kokuvezwa isikhathi eside, okuvimbela ukuvuza koketshezi nokugqwala kwezingxenye zemishini, okuqinisekisa ukusebenza okuzinzile kwemishini ezindaweni eziyinkimbinkimbi zamakhemikhali.
4. Isikhundla kanye Nomsebenzi Wezimbozo Ezixhunyanisiwe Ezimbili Ezinjinini
Kusukela esithombeni, kungabonakala ukuthi uphawu lwezixhumi ezimbili lufakwe ngokuyinhloko phakathi kwe-input manifold kanye ne-engine block, kanye naphakathi kwe-cylinder block kanye ne-cylinder head. Kulezi zindawo ezibalulekile, uphawu lwezixhumi ezimbili ludlala indima ebalulekile ekuvaleni. Ingxenye yendandatho yesikwele ifanelana kahle nokuxhumana phakathi kwekhanda lesilinda kanye ne-cylinder block, ivimbela ngempumelelo ukuvuza kukawoyela wenjini kanye ne-coolant futhi iqinisekise ukuthi uketshezi olungaphakathi kwenjini lugcina imisebenzi evamile yokuthambisa nokupholisa ngaphansi kwamazinga okushisa aphezulu, ukucindezela okuphezulu, kanye nokudlidliza. Ingxenye yendandatho ye-elliptical ifakwe phakathi kwe-input manifold kanye ne-cylinder block, iqinisekisa ukuvalwa kwenqubo yokungenisa ukuze umoya noma izingxube ezivuthayo zingene ngesilinda ngasinye ngokufanayo nangokunembile, ngaleyo ndlela kuqinisekiswe ukusebenza kahle kokushisa kwenjini kanye nokukhishwa kwamandla. Lokhu kwethulwa okunembile akuvumeli nje kuphela abantu abaningi ukuthi bathole ukuqonda okujulile kophawu lwezixhumi ezimbili kodwa futhi kunikeza izinto zokubhekisela ezibalulekile kochwepheshe bemboni, okukhuthaza ukushintshana kanye nokusungula ubuchwepheshe bokuvala.
