Isivalo sokunweba imoto singavuza uma siqiniswe kakhulu.
Ukuqinisa kakhulu isivalo sokunwebeka semoto kungabangela ukuvuza. Isizathu esiyinhloko ukuthi ukuqinisa ngokweqile kungabangela ukuthi isivalo siwohloke, sonakalise i-gasket yokuvala, noma kuthinte ukusebenza okuvamile kwevalvu yokukhulula ingcindezi.
Izizathu zokuvuza ngenxa yokuqina ngokweqile
Ukuguquka kwe-cap: I-expansion cap ivame ukwenziwa ngepulasitiki noma ngerabha. Ukuqinisa kakhulu kungabangela ukuthi ibole unomphela, kubhubhise isakhiwo sokuvala, futhi kuvumele i-coolant ukuthi ivuze.
Ukungasebenzi kahle kwevalvu yokukhulula ukucindezeleka: Isivalo sokunweba siqukethe ivalvu yokukhulula ukucindezeleka ukulawula ukucindezeleka ohlelweni lokupholisa. Ukuqinisa kakhulu kungalimaza ivalvu noma kuyivimbele ekuvulekeni kahle, okubangela ukuthi i-coolant ivuze ngezikhala lapho ukucindezeleka kungenakudedelwa.
Umonakalo we-gasket yokuvala: Ukuqinisa kakhulu kungacindezela i-gasket yokuvala, okubangela ukuthi iphazanyiswe noma iqhekeke, kulahlekelwe umsebenzi wayo wokuvala.
Indlela efanele yokuphatha
Qinisa ngokulingene: Uma ufaka isivalo sokunweba, siqinise kuphela kuze kube nokumelana okuncane. Gwema ukuqinisa ngokweqile. Ngokuvamile, uma uzwa umsindo othi "chofoza" noma uzwa ukumelana okukhulu, yeka ukuqinisa.
Hlola futhi ushintshe izingxenye ezonakele: Uma kuvela ukuvuza ngenxa yokuqina ngokweqile, qala uhlole ukuthi isivalo sikhubazekile noma i-gasket yonakele. Uma kukhona umonakalo, shintsha isivalo noma i-gasket ngesinye esisha esifanela imoto yokuqala.
Qinisekisa isimo sesistimu yokupholisa: Ngemva kokushintsha, qala injini bese ubheka ukuthi kusekhona yini ukuvuza futhi uqinisekise ukuthi izinga le-coolant lingaphakathi komugqa wesikali ukuze kutholakale amanye amaphutha.
Iziphakamiso zokunakekelwa kwansuku zonke
Ukuhlolwa okuvamile: Hlola isivalo sokunweba kanye nesistimu yokupholisa ukuze ubone ukuthi kukhona yini izimpawu zokuvuza njalo ezinyangeni ezimbalwa ukuqinisekisa ukuthi ivalvu yokukhulula ingcindezi ayivalwanga.
Sebenzisa i-coolant ejwayelekile: Gwema ukufaka amanzi empompini ukuvimbela ukugqwala kwesistimu noma ukuvaleka kwamavalvu ngokungcola.
Ukulungiswa kobungcweti: Uma ukuvuza kuqhubeka, kunconywa ukuthi uye esitolo sokulungisa ukuze wenze ukuhlolwa okuphelele kohlelo lokupholisa ukuze uvimbele ukushisa kakhulu kwenjini kanye nomonakalo.
Isimiso sokusebenza esinemininingwane se-expansion cap
Isivalo sokunweba silawula ingcindezi yesistimu yokupholisa ngaphakathi nge-valve yokukhulula ingcindezi kanye ne-vacuum valve. Sikhipha igesi eningi lapho injini ishisa futhi sigcwalise i-coolant uma iphola, sigcine ukusebenza okuzinzile kwesistimu.
Imisebenzi eyinhloko kanye nezindima
Ukulawulwa kwengcindezi: Lawula ingcindezi yesistimu yokupholisa ngaphakathi kwebanga eliphephile (ngokuvamile ibha engu-0.12–1.2) ukuvimbela ukuqhuma kwamapayipi ngenxa yengcindezi enkulu noma ukuvaleka komoya ngenxa yengcindezi enganele.
Ukuphathwa kwe-coolant: Munca izinguquko zevolumu ezibangelwa ukwanda nokuncipha kokushisa (cishe u-5%–8%), ugweme ukuvuza noma ukuntuleka kwe-coolant.
Isimiso sokusebenza ngesinyathelo ngesinyathelo
Isigaba sokushisa injini (ukwanda kwengcindezi)
Isibandisi siyakhula ngenxa yokushisa, futhi ingcindezi yesistimu idlula umkhawulo (isb., 0.12 MPa).
I-valve yokukhulula ukucindezeleka ivuleka ngokuzenzakalelayo: Ikhipha umusi kanye negesi eningi esivimbelweni sokunweba, bese ukucindezeleka kuyehla ngemva kokuvala i-valve.
Umsebenzi: Kuvimbela umonakalo wethangi lamanzi noma ipayipi, bese i-radiator iqala ukuphola.
Isigaba sokupholisa injini (ukwehla kwengcindezi)
Isibandisi siyafinyela, bese kwakheka ingcindezi engemihle ohlelweni.
I-vacuum valve ivuleka ngokuzenzakalelayo: Ivumela i-coolant esesivalweni sokunweba ukuthi igeleze ibuyele ekujikelezeni kwegazi okuyinhloko, igcwalise izinga lesistimu.
Umsebenzi: Kuvimbela ukuvaleka komoya (ukuvaleka komoya), kuqinisekisa ukugeleza komoya opholile okuqhubekayo.
Izingxenye ezibalulekile kanye nomklamo
Ivalvu yokukhulula ukucindezeleka: Isakhiwo sesiphethu noma esizwela ukucindezeleka esivuleka ukuze sikhiphe ugesi lapho sicindezelwe kakhulu (>1.2 bar).
I-vacuum valve: Umklamo we-valve ohamba ngendlela eyodwa ovula isiteshi sokubuya lapho ucindezelwa kancane.
Uhlelo lokuvala: I-gasket yerabha kanye nesivalo esinezintambo kuqinisekisa ukungabi nomoya, kunciphisa ukuminyana kwe-coolant.
