Imoto nganye inenkqubo yokufudumeza ye-cabin ehambelana nenkqubo yokupholisa injini.Iimpompo zokufudumala zombane zisetyenziswa ngokubanzi ukulawula isitofu namhlanje - funda ngezi zixhobo, iintlobo zazo, ukuyila, umgaqo wokusebenza, kunye nokukhethwa kwazo kunye nokutshintshwa kweli nqaku.
Yintoni impompo yesifudumezi sombane?
I-valve yokufudumala yombane (i-valve yokulawula i-heater yombane, i-valve yokufudumala) - icandelo lenkqubo yokufudumala ye-compartment yabagibeli / i-cabin yezithuthi;Ivalve okanye ivalve yokulawula unikezelo lwesipholisi ukusuka kwisixokelelwano sokupholisa se-injini ukuya kwiradiyetha (isifudumezi sobushushu) sesifudumezi.
I-crane elawulwa ngombane ifana ne-crane yomatshini, kodwa iqhutywa yimoto yombane eyakhelwe ngaphakathi okanye i-solenoid.Esi sisombululo senza ukuba sikwazi ukushiya i-cable drive kunye nokuphumeza ulawulo lwe-heater usebenzisa iqhosha.Iikrane zombane zenza ukuba kube lula ukuphumeza izicwangciso ezahlukeneyo zokufudumeza i-cabin kunye nokusebenza kwenkqubo yokupholisa injini, ngelixa zilula ukuyisebenzisa, zithembeke ekusebenzeni kwaye zinoyilo olulula.
Iindidi, uyilo kunye nomgaqo wokusebenza kwevalve yokufudumala yombane
Iivalve zanamhlanje ezilawulwa ngombane zihlulwe ngokwamaqela ngokohlobo lwento yokuvala kunye nokuqhuba kwayo, kunye nenani leesekethe (kwaye, ngokufanelekileyo, imibhobho).
Ngokwenani leesekethe kunye nemibhobho, iivalve zesifudumezi zezi:
• Isetyhula enye/2-nozzle - iivalve/iivalvu eziqhelekileyo;
• I-Double-circuit / 3-nozzle - i-valve yeendlela ezintathu.
Iivalvu zesebe eliphindwe kabini zizivalo ezinokuvula nokuvala kuphela ukuhamba kolwelo.Kwivalve enjalo, umbhobho omnye ngumbhobho wokungena, okwesibini ngumbhobho wokukhupha, kwaye into yokuvala iphakathi kwabo.Ivalve yesifudumezi enemilomo emibini isetyenziswa kwiinkqubo zesiqhelo zangaphakathi zokufudumeza, ibekwe phakathi kombhobho wokuphuma wenkqubo yokupholisa ye-injini kunye nombhobho wokungena weradiyetha yesitovu, ibonelela ngolawulo lokuhamba kwesipholisi esishushu.
Iskimu esiqhelekileyo sokupholisa injini kunye neenkqubo zokufudumeza zangaphakathi
Iivalvu zendlela-ntathu ziivalvu ezindlela-ntathu ezinokuthi zilawule ukuhamba kolwelo kwimibhobho emibini eyahlukeneyo.Le valve inombhobho wokungena omnye kunye nemibhobho emibini yokukhupha, kwaye into evaliweyo yenzelwe ngendlela enokuthi iqondise ulwelo olusuka kumbhobho wokungena komnye wemibhobho yokukhupha, ngelixa ivalela okwesibini.I-valve yokufudumala enemibhobho emithathu ingasetyenziselwa kwiinkqubo ezahlukeneyo zokufudumeza kwangaphakathi: kunye ne-bypass, kunye ne-heater eyongezelelweyo, njl.
Ngokohlobo lwento yokuvala kunye nokuqhuba kwayo, iivalve zezi:
• Amasango ezilayidi aqhutywa yinjini yombane;
• Ukuvalwa okuqhutywa yi-Solenoid.
Uyilo lweekhreyini zesilayidi lulula.Zisekelwe kumzimba owenziwe ngeplastiki kunye nemibhobho, ngaphakathi apho kukho ipleyiti ejikelezayo ngendlela yecandelo eliqinileyo okanye icandelo elinemingxuma ngokobukhulu bemibhobho.I-motor compact yombane ene-gear reducer elula ifakwe emzimbeni, ngoncedo apho iplate ijikeleziswa.Kwiivalve ezinemibhobho emibini (i-double-circuit), zombini iipayipi zijongene nomnye, phakathi kwazo kukho ipleyiti.Kwiivalvu ezinemibhobho emithathu, kukho umbhobho wokungena kwelinye icala, kunye neepayipi ezimbini zokukhupha kwelinye icala.
Ivalve yesifudumezi enenjini yombane isebenza ngolu hlobo lulandelayo.Xa isitofu sivaliwe, i-tap plate ibekwe phakathi kwemibhobho, ivimbela ukuhamba kwamanzi - kulo mzekelo, i-liquid eshushu ayifaki i-radiator yokufudumala, inkqubo yokufudumala yangaphakathi ayisebenzi.Ukuba kuyimfuneko ukuvula isitovu, umqhubi ucofa iqhosha kwideshibhodi, okwangoku unikezelwa kwi-motor yombane ye-crane, ijika iplate kwaye ivule indlela yokupholisa - i-radiator yokufudumala iyatshisa, ngaphakathi. inkqubo yokufudumeza iqala ukusebenza.Ukucima isitofu, umqhubi ucofa iqhosha kwakhona, zonke iinkqubo zenzeke ngokulandelelana, kwaye isitofu siyacima.
Ivalve yesifudumezi enemilomo emithathu phambi kwe-bypass kwindlela yokufudumala isebenza ngokulula.Xa isitovu sicinyiwe, ipleyiti ejikelezayo ikwindawo yokuba isixhobo sokupholisa sidlule kwivalve size singene kwindawo yokupholisa ye-injini (impompo) ngombhobho wokukhupha umoya.Xa isitovu sivuliwe, ipleyiti iyajika, ivale i-outlet enye kwaye ivule eyesibini - ngoku ukuhamba kolwelo kudlula ngokukhululekileyo kwirediyetha yesifudumezi, kwaye ukusuka kuyo kungena kumbhobho wokukhupha kunye nokungena kwenkqubo yokupholisa injini.Xa isitovu sicinyiwe, zonke iinkqubo zenzeka ngokulandelelana.
Uyilo lweevalvu ze-solenoid ezivaliweyo zihlukile.Zisekelwe kwicala leplastiki, ngaphakathi apho kukho isango eliphakamisayo ngendlela ye-cone enqanyuliweyo.Kwindawo evaliweyo, i-shutter ihlala kwisali yayo, iqinisekisa ukuba ukuhamba kwamanzi kuvaliwe.Isango lixhunywe ngendlela yentonga kwi-armature ye-solenoid, efakwe kumzimba we-crane.Iivalve ezijikeleza kabini zinokuba yinye kunye ne-double-solenoid.Kwimeko yokuqala, zombini izinto zokukhiya zibekwe kwintonga ye-solenoid, okwesibini, into nganye yokutshixa ilawulwa yi-solenoid yayo.
Umbhobho wokufudumala nge-solenoid
Ukusebenza kwevalve ye-solenoid yesifudumezi kulula.Iivalve ngokuqhelekileyo zivulekile - ngaphandle kwe-voltage kwi-solenoid, i-shutter iphakanyiswe ngumthombo, umjelo uvulekile.Xa injini iqala, i-voltage isetyenziswa kwi-solenoid kwaye ivalve iyavala.Xa isitovu sivuliwe, i-solenoid i-de-energized, impompo ivula kwaye inikeze ulwelo olushushu kwi-radiator yokufudumeza.Xa isitofu sicinyiwe, i-voltage iphinda isetyenziswe kwi-solenoid kwaye itephu iyavala.Ivalve ye-double-circuit valve isebenza ngokufanayo, kodwa enye yeesekethe zayo ihlala ivala xa i-ignition ivuliwe - oku kuthintela ukunikezelwa kwesipholisi kwi-radiator yokufudumala, ulwelo luhamba kunye ne-bypass.Xa isitofu sivuliwe, iisekethe zitshintshwa, i-coolant ingena kwi-radiator yokufudumala, xa isitofu sivaliwe, ipompo ibuyela kwindawo yayo yangaphambili.Zombini i-solenoids yevalve ephindwe kabini ayize ivule okanye ivale ngaxeshanye (ngaphandle kokucima amandla xa omabini amasango evuliwe).
Imilomo yeevalvu zazo zonke iindidi i-serrated, le milo iqinisekisa ukuhambelana okuqinileyo kwemibhobho yerabha.Ukufakwa kwemibhobho kwimibhobho kuqhutyelwa ngokusebenzisa i-clamps yensimbi, i-crane ngokwayo idla ngokuxhoma ngokukhululekile kwimibhobho (ekubeni inobunzima obuphantsi).I-crane iqhagamshelwe kwisixokelelwano sombane usebenzisa isiqhagamshelo sombane esiqhelekileyo.
Namhlanje, iivalve zesifudumezi sombane zisetyenziswa kakhulu kwiimoto zasekhaya nezangaphandle, ziye zatshintsha ii-analogues zoomatshini kwaye zenza ukuba ulawulo lwesitovu sangaphakathi lube lula ngakumbi.
Imiba yokukhetha kunye nokutshintshwa kwevalve yesifudumezi
I-valve yokufudumala ibaluleke kakhulu ekusebenzeni kwenkqubo yokufudumala yangaphakathi / i-cabin, kodwa ukukhethwa kunye nokutshintshwa kwale nxalenye kwiimeko ezininzi akubangeli naziphi na iingxaki.Ukukhetha i-crane efanelekileyo, kufuneka ulandele iingcebiso ezimbalwa:
• Amandla ombane ombane we-crane motor kufuneka ahambelane nombane wombane womnatha wombane okwibhodi yesithuthi - 12 okanye 24 V;
• Uhlobo lwe-crane - i-2 okanye i-3 imibhobho - kufuneka ihambelane neskimu senkqubo yokufudumala yangaphakathi.Kwiinkqubo eziqhelekileyo, i-crane enemibhobho emibini iyadingeka, kwiinkqubo ezine-bypass, i-valve enemibhobho emithathu iyadingeka.Kwakhona, i-faucet enemibhobho emithathu ingasetyenziselwa ukudala inkqubo yokufudumala kunye ne-heater eyongezelelweyo;
• Ububanzi beemibhobho kufuneka buhambelane nobubanzi beepayipi zenkqubo yokufudumala, kodwa ukuba kuyimfuneko, i-adapters ingasetyenziswa;
• Kufuneka kubekho uhlobo olunye lwesinxibelelanisi sombane kwikhreyini nakwimoto.Ukuba kuyimfuneko, kuyimfuneko ukutshintsha uhlobo lokudibanisa kwimoto;
• Ikhreyini kufuneka ibe nemilinganiselo efanelekileyo yokufakela kwayo.
Ukutshintshwa kwevalve yesifudumezi kufuneka kwenziwe emva kokukhupha amanzi okupholisa, izibophelelo zentsimbi kufuneka zisetyenziselwe ukufakela.Kuyimfuneko ukubeka esweni ukufakwa okuchanekileyo kwevalve - beka iipayipi zayo zokungena kunye nokuphuma ngokuhambelana nolwalathiso lwe-liquid.Ukuze kube lula, iintolo zisetyenziswa kwimilomo ebonisa icala lokuhamba kolwelo.Ukuba i-valve ye-2-nozzle eqhelekileyo ifakwe ngokungalunganga, inkqubo iya kusebenza, kodwa ukufakwa okungafanelekanga kwe-valve ye-3-nozzle kuya kwenza inkqubo ingasebenzi ngokupheleleyo.Ngokufakela okuchanekileyo nokuthembekileyo kwe-crane, isitofu siya kuqalisa ukusebenza ngokukhawuleza, ukubonelela ngokufudumala kunye nokuthuthuzela emotweni.
