Inhloso nomgomo wokusebenza kwe-thermostat yesistimu yokupholisa

Injini evuthayo yangaphakathi, ikakhulukazi yesimanje kanye nobuchwepheshe obuphezulu, iwumshini owenziwe ngokunemba okuphezulu. Wonke umsebenzi wakhe ulungiselelwe izinga elithile lokushisa kuzo zonke izingxenye. Ukuphambuka embusweni oshisayo kuholela ekuwohlokeni kwezici zenjini, ukwehla kwensiza yayo, noma ngisho nokuwohloka. Ngakho-ke, izinga lokushisa kufanele lilawulwe ngokunembile, lapho idivayisi engezwani nezinga lokushisa, i-thermostat, yethulwa ohlelweni lokupholisa.

Umklamo ojwayelekile nomgomo wokulawula

I-coolant (epholile) ohlelweni iqhutshwa ngokuqhubekayo ngepompo yamanzi - iphampu. I-antifreeze eshisayo, eye yadlula eziteshini zokupholisa ku-block kanye nekhanda lemoto, ingena ekungeneni kwayo. Kungalesi sikhathi lapho kungcono kakhulu ukubeka idivayisi ukuze kugcinwe umbuso wokushisa ojwayelekile.

Ku-thermostat yemoto evamile, kunezingxenye ezimbalwa eziqinisekisa ukusebenza kwayo:

• isilinda sokulawula esiqukethe isigcwalisi sento ekhethiwe ngenxa yezizathu zokushintsha umthamo omkhulu ngemva kokushisa;
• ama-valve alayishwe entwasahlobo avala futhi avule izifunda ezimbili eziyinhloko zokugeleza kwamanzi - ezincane nezinkulu;
• amapayipi amabili okungena lapho kugeleza i-antifreeze, ngokulandelana, kusuka kumasekethe amancane namakhulu;
• ipayipi eliphumayo elithumela uketshezi endaweni yokungena yepompo;
• izindlu zensimbi noma zepulasitiki ezinezimpawu.

Uma izinga lokushisa loketshezi linganele, isibonelo, lapho uqala futhi ufudumeza injini ebandayo, i-thermostat ivaliwe, okungukuthi, ukugeleza konke okushiya injini kubuyiselwa emuva ku-impeller futhi ukusuka lapho futhi kuya kumajakhethi okupholisa. . Kukhona ukujikeleza embuthanweni omncane, kudlula irediyetha yokupholisa. I-Antifreeze ithola ngokushesha izinga lokushisa, ngaphandle kokuvimbela injini ukuthi ingangeni kwimodi yokusebenza, kuyilapho ukushisa kwenzeka ngokulinganayo, ukuguqulwa kokushisa kwezingxenye ezinkulu kugwenywe.

Lapho umkhawulo ophansi wokusebenza ufinyelelwa, isigcwalisi ku-cylinder yesigqila se-thermostat, esigezwe yi-coolant, sinwebeka kangangokuthi ama-valve aqala ukuhamba ngesiqu. Imbobo yesifunda esikhulu ivuleka kancane, ingxenye yesipholisi iqala ukugeleza ku-radiator, lapho izinga lokushisa layo lehla khona. Ukuze i-antifreeze ingahambi ngendlela emfushane ngepayipi elincane lesifunda, i-valve yayo iqala ukuvala ngaphansi kwethonya lesici esifanayo esizwela ukushisa.

Isilinganiso phakathi kwezigaba zamasekethe amancane namakhulu okugeleza ku-thermostat kuyashintsha kuye ngokushisa koketshezi olungena endlini, yile ndlela ukulawulwa okwenziwa ngayo. Lena imodi ezenzakalelayo yokuqinisekisa ukuthi ukusebenza kahle kuyagcinwa. Ephuzwini elidlulele, ukugeleza konke kuzoqondiswa kumjikelezo omkhulu, encane ivaliwe ngokuphelele, amandla e-thermostat aphelile. Ukuhlenga okwengeziwe kwemoto ekushiseni ngokweqile kwabelwa izinhlelo eziphuthumayo.

Izinhlobo zama-thermostats

Amadivayisi alula anevalvu eyodwa awasasetshenziswa noma kuphi. Izinjini zesimanje ezinamandla zikhipha ukushisa okuningi, kuyilapho zifuna ukunemba kokugcina umbuso. Ngakho-ke, imiklamo eyinkimbinkimbi nakakhulu iyathuthukiswa futhi isetshenziswe kunomklamo ochazwe wama-valve amabili.

Ngokuvamile ungathola okushiwo i-thermostat ye-electronic. Akukho ukugxila okukhethekile okuhlakaniphile kuwo, kungenzeka nje ukushisa kukagesi kwesici esisebenzayo sengeziwe. Kunjengokungathi, kukhohlisiwe, ukusabela hhayi kuphela ku-antifreeze yokugeza, kodwa futhi namandla akhishwe ikhoyili yamanje. Kwimodi yomthwalo oyingxenye, kuzoba nenzuzo eyengeziwe ukukhulisa izinga lokushisa elipholile libe yinani eliphakeme elingama-degree angama-110, futhi, ngokuphambene nalokho, linciphise libe cishe ku-90. Lesi sinqumo senziwe uhlelo lweyunithi yokulawula injini, okunikeza amandla kagesi adingekayo entweni yokushisa. Ngale ndlela ningakwazi nobabili ukukhulisa ukusebenza kahle kwemoto, futhi uvimbele izinga lokushisa ukuthi lisuke ngokushesha lidlule umkhawulo oyingozi emithwalweni ephezulu.

Kukhona futhi ama-thermostats aphindwe kabili. Lokhu kwenziwa ukuze kulawulwe ngokwehlukana izinga lokushisa le-block kanye nekhanda le-cylinder. Lokhu kuqinisekisa ukuthuthuka ekugcwaliseni, ngakho-ke amandla, ngakolunye uhlangothi, nokufudumala okusheshayo ngokunciphisa ukulahleka kokungqubuzana, ngakolunye. Ukushisa kwebhulokhi kuphakeme ngamadigri ayishumi kunekhanda, ngakho-ke amakamelo omlilo. Phakathi kokunye, iphinde yehlise ukuthambekela kwezinjini ze-turbo kanye nezinjini ezifisa ukucindezelwa ngokwemvelo ukuthi ziqhume.

Ukuxazulula izinkinga nokulungisa

Ukwehluleka kwe-thermostat kungenzeka kunoma yisiphi isimo. Ama-valve ayo ayakwazi ukuqhwanda kokubili kumodi yokujikeleza yesifunda esincane noma esikhulu, futhi endaweni ephakathi. Lokhu kuzobonakala ngokushintsha kwezinga lokushisa elivamile noma ukuhlanekezelwa kwezinga lokukhula kwayo ngesikhathi sokufudumala. Uma injini yokonga ihlale isebenza nge-valve enkulu yendilinga evulekile, ngakho-ke akunakwenzeka ukuthi ifinyelele izinga lokushisa lokusebenza nhlobo ngaphansi kwezimo ezijwayelekile, futhi ebusika lokhu kuzoholela ekuhlulekeni kwe-heater yangaphakathi.

Ukugqagqana kancane kwamashaneli kuzokwenza injini isebenze ngendlela engalindelekile. Izoziphatha kabi ngokulinganayo ngaphansi komthwalo osindayo kanye nemodi yokufudumala. Izinguquko ezinjalo kufanele zibe isignali yokuhlola ngokushesha i-thermostat, ama-motor azwela kakhulu ngokweqile nokuntuleka kokushisa.

Ama-thermostat awakwazi ukulungiswa, ukushintshwa okungenamibandela kuphela. Inani lomsebenzi kanye nentengo yenkinga kuncike ekwakhiweni okuqondile. Kwezinye izimoto, isici esisebenzayo esinama-valve kanye nesici esizwela ukushisa siyashintshwa, kwezinye - i-thermostat enomhlangano wezindlu. Ithuluzi eliyinkimbinkimbi eliphindwe kabili noma elilawulwa ngogesi linezindleko ezibucayi kakhulu. Kodwa ukulondoloza akufanelekile lapha, ingxenye entsha kufanele ibe ngeyokuqala noma evela kubakhiqizi abadume kakhulu, ngezinye izikhathi iba yintengo ephakeme nakakhulu kuneyokuqala. Kungcono ukuthola ukuthi yimaphi amadivaysi enkampani asetshenziselwa imishini yokuthutha yale modeli, futhi uyithenge. Lokhu kuzoqeda ukukhokhwa ngokweqile komkhiqizo woqobo, kuyilapho kugcinwa ukwethembeka kwengxenye yokuqala.

Kuye kwaqashelwa ukuthi ukwehluleka kwe-thermostat kuvame ukwenzeka phakathi nokugcinwa okuvamile kwesistimu yokupholisa. Ikakhulukazi ngemva kokufaka i-antifreeze, ikakhulukazi uma ingazange ivuselelwe isikhathi eside.

Amadivayisi awakuthandi ukucindezelwa okuhambisana nokuhlala kokuqala endaweni evele ingenabungane yesipholile esigugile kanye nezithasiselo ezithuthukisiwe, ezithathelwa indawo imikhiqizo yokubola. Kanye nokuchayeka isikhathi esifushane emoyeni onothile nge-oxygen, osekuseduze nokwehluleka. Ngakho-ke, uma i-thermostat inento eshintshwayo engabizi ukuyithenga, kunengqondo ukuyishintsha ngokushesha ufake entsha. Ngakho-ke, umshayeli uzosinda ezinkingeni ezingase zibe khona kanye nokuvakasha okuphindaphindiwe esiteshini sesevisi.

Uma umnikazi enengqondo ethanda ukwazi futhi ethanda ukuhlola imininingwane ngezandla zakhe, khona-ke ukusebenza komhlangano osebenzayo we-thermostat kungabhekwa ngokubheka ukunyakaza kwama-valve ayo ngesikhathi sokubilisa esitofu endishini esobala. Kodwa lokhu akuwenzi umqondo okhethekile; amadivaysi amasha avela kumkhiqizi onedumela elihle ahlala esebenza kumgomo othi "ukusetha futhi ukhohlwe". Futhi resuscitation endala ikhishwe ngenxa yezizathu ukwethembeka imoto.
