Indima Enkulu Esikhaleni Esincane: Umsebenzi kanye Nokuphathwa Kwephutha Kwesivalo Sikawoyela Se-Engine Valve
Ohlelweni olunembile lwenjini yemoto, uphawu lukawoyela lwe-valve luyinto evame ukunganakwa kodwa ebaluleke kakhulu. Lufana "nomlindi wesango" wenjini, edlala indima engenakuphindwa ekuqinisekiseni ukusebenza kahle nokuzinzile kwenjini.
Umsebenzi Oyinhloko Wesivalo Samafutha
I-valve oil seal ifakwa kakhulu ngaphezu komhlahlandlela we-valve, iyingxenye ebalulekile yokuvala isitimela se-valve yenjini. Umsebenzi wayo oyinhloko ubonakala ngezici ezintathu. Okokuqala, ingavimbela ngempumelelo uwoyela wenjini ukuthi ungene emapayipini okungenisa kanye nawokukhipha kanye negumbi lokushisa. Lapho injini isebenza, uwoyela wenjini usesimweni sokuhamba okuqhubekayo. Ngaphandle kokuvinjelwa kwe-valve oil seal, uwoyela wenjini uzogeleza eduze kwesiqu se-valve uye emapayipini okungenisa kanye nawokukhipha kanye negumbi lokushisa, hhayi nje kuphela okubangela ukulahlekelwa okungadingekile uwoyela wenjini kodwa futhi okuholela ekushiseni okungaphelele, ukusetshenziswa kukaphethiloli okwandisiwe, kanye nokuguguleka okukhulu kwezingxenye zenjini. Okwesibili, i-valve oil seal ingavimbela ingxube kaphethiloli nomoya kanye negesi yokukhipha ekuvuzeni. Ukuvuza kwengxube kanye negesi yokukhipha kuzophazamisa indawo yokuvala yenjini, okuholela ekunciphiseni ukusebenza kahle kokushisa, ukuphazamiseka kokusebenza kwamandla, kanye nokwanda kokukhishwa komoya, okubangela ukungcola emvelweni. Ngaphezu kwalokho, i-valve oil seal ingaqinisekisa ukugeleza okufanele kukawoyela wenjini, inikeze ukuthambisa okuhle kanye nokuvikelwa kwezingxenye ezahlukene zenjini, ivimbele amadiphozithi ekhabhoni ngenxa yokugeleza okungalungile kukawoyela wenjini, futhi yandise impilo yenkonzo yenjini.
Isivalo sikawoyela se-valve ngokuvamile senziwa ngokuhlanganisa uhlaka lwangaphandle kanye ne-fluororubber ndawonye. Ingxenye ye-radial ifakwe intwasahlobo eziqinisayo noma ucingo lwensimbi. Lesi sakhiwo siyenza ikwazi ukunamathela eduze kumhlahlandlela we-valve endaweni enokushisa okuphezulu kanye nokucindezela okuphezulu, igcina ukusebenza okuhle kokuvala ngisho nangaphansi kwezimo ezinjalo. Ngenxa yokuxhumana isikhathi eside nophethiloli namafutha enjini kanye nokusebenza emazingeni okushisa aphezulu, isivalo sikawoyela se-valve ngokuvamile senziwe ngezinto ze-fluororubber ezinokumelana okuhle kokushisa kanye nokumelana namafutha.
Izimpawu Ezijwayelekile Zamaphutha Okuvala Amafutha E-Valve
Njengoba imoto isetshenziswa ngokuhamba kwesikhathi, uphawu lwamafutha e-valve luzokhula kancane kancane futhi luguge, ngaleyo ndlela lubangele uchungechunge lwamaphutha. Izimpawu ezivamile eziyinhloko zifaka: 1. Ukusetshenziswa kakhulu kukawoyela kanye nokukhishwa komoya okungavamile. Lesi yisibonakaliso esisobala kakhulu somonakalo wophawu lwamafutha e-valve. Uwoyela wenjini uzogeleza eduze kwesiqu se-valve ungene ekamelweni lokushisa ukuze ushiswe, okubangela intuthu eluhlaza okwesibhakabhaka epayipini lokukhipha umoya ngesikhathi sokuqala okubandayo, kanye nentuthu eluhlaza okwesibhakabhaka esobala kakhulu ngesikhathi sokusheshisa okusheshayo. Ipayipi lokukhipha umoya lingase linamathele noma libe namabala kawoyela, futhi kungatholakala iphunga likawoyela wenjini elishisiwe. 2. Ukwanda okungavamile kokusetshenziswa kukawoyela wenjini. Ngokuvamile, ukusetshenziswa kukawoyela wenjini kuhamba kancane, kudinga inani elincane kuphela lokugcwaliswa kabusha njalo ngamakhilomitha ayizinkulungwane ezimbalwa. Kodwa-ke, lapho uphawu lwamafutha e-valve lonakele, ukusetshenziswa kukawoyela wenjini kuzokhula ngokuzumayo. Ukukhanya kukawoyela kungakhanya ngemva kokuhamba amakhilomitha ayizinkulungwane ezimbalwa kuphela uma kungalungiswanga ngokushesha, futhi injini ingase ibe nomonakalo omkhulu ngenxa yokunganeli kukawoyela wenjini. 3. Ukwehla kwamandla enjini. Uwoyela wenjini ongena ekamelweni lokushisa uzonciphisa ingxube, okuthinta ukusebenza kahle kokushisa. Ngesikhathi esifanayo, ukuthambekela kwevalvu kuzobangela ukuvalwa kwesilinda okungekuhle, okuholela ekunciphiseni kwengcindezi yesilinda futhi kwenze injini isheshise kancane noma ingabi namandla anele lapho ikhuphuka noma idlula. 4. Inkinga yokwanda kwediphozithi yekhabhoni. Uwoyela wenjini ongena kwisilinda awushiswa ngokuphelele, okuholela enanini elikhulu lediphozithi yekhabhoni enamathela kuvalvu, i-piston, kanye ne-spark plug, okubangela ukuthi ivalvu ivaleke ngendlela engafanele kanye ne-spark plug ivuthe kabi, okwenza inkinga yokulahlekelwa amandla kanye nokusetshenziswa kukaphethiloli okwandisiwe ibe nkulu kakhulu.
Ukuphatha Nokuvimbela Amaphutha Okuvala Amafutha E-Valve
Uma kutholakala iphutha le-valve oil seal, kufanele lilungiswe ngokushesha noma lishintshwe. Ngesikhathi senqubo yokulungisa, khetha imikhiqizo ye-valve oil seal ethembekile enezinto nezinqubo ezihlangabezana nezidingo. Ngesikhathi sokufaka, landela ngokuqinile izinqubo zokusebenza ukuqinisekisa ukuthi udebe lwe-valve oil seal luqondile esiqwini se-valve, ugweme ukwehluleka kokuvala ngenxa yokufakwa okungafanele.
Ekushayeleni kwansuku zonke, ukuhlolwa nokugcinwa njalo kuyisihluthulelo sokuvimbela amaphutha esivikelo sikawoyela we-valve. Abashayeli kufanele bahlakulele umkhuba wokuhlola njalo i-dipstick kawoyela nokunaka ukusetshenziswa kukawoyela. Uma ukusetshenziswa kukawoyela kushesha kakhulu, phenyisisa imbangela ngokushesha. Ngesikhathi esifanayo, ngokuhambisana nezidingo zencwadi yokulungisa imoto, kuyadingeka ukushintsha uwoyela wenjini kanye nesihlungi sikawoyela njalo ukuze kugcinwe uwoyela uhlanzekile futhi kugwenywe ukuvala imigodi yokubuyela kukawoyela ekhanda lesilinda ngenxa kawoyela ongcolile, okungaholela ekungasebenzi kahle kwesivikelo sikawoyela we-valve.
Ekuphetheni, yize uphawu lukawoyela lwe-valve luncane, luhlobene kakhulu nokusebenza kahle kanye nesikhathi sokuphila kwenjini. Ukuqonda umsebenzi wophawu lukawoyela lwe-valve, ukuqonda izimpawu zalo zamaphutha kanye nezindlela zokuxazulula izinkinga kubalulekile ukuqinisekisa ukusebenza okuvamile kwemoto. Abanikazi bezimoto kufanele banake kakhulu ngesikhathi sokushayela nsuku zonke, bathole futhi balungise izinkinga kusenesikhathi, futhi benze le ngxenye encane idlale indima ebalulekile.
