2021-08-11

E pheha ebe e fetoha e tloaelehileng feela ka mor'a ho etsa metsi a pholileng. Tlhahlobo le tlhahlobo:
(1) Ha enjene e chesa ka tšohanyetso nakong ea ho khanna, ela hloko pele boemo bo matla ba ammeter. Haeba ammeter e sa bontše ho tjhaja ha ho eketsa throttle, 'me nale ea gauge e lokolloa feela ke 3 ~ 5A Hang-hang swing khutlela ho "0" boemo bo bontša hore lebanta la fan le robehile. Haeba ammeter e bontša ho tjhaja, koala enjene ebe o ama radiator le enjene ka letsoho. Haeba mocheso oa enjene o phahame haholo 'me mocheso oa radiator o le tlaase, o bontša hore pompo ea pompo ea metsi le impeller e hlephile, e sitisa ho potoloha ha metsi a pholileng; Haeba phapang ea mocheso pakeng tsa enjene le radiator e se kholo, hlahloba hore na ho na le ho lutla ho hoholo ha metsi tsamaisong ea pholileng. Ka mor'a ho lemoha, mocheso oa enjene o phahame haholo 'me mocheso oa radiator o tlaase haholo,' me pompo ea metsi e na le mathata;

(2) Thempereichara ea metsi a pholileng e nyoloha ka potlako qalong ea ho qala, e leng ho fellang ka ho bela ha metsi a pholileng. Belofo e ka sehloohong ea thermostat e nang le mefuta e mengata ea thermostat e oa 'me e ts'oarella ka har'a phaephe e kenang ea metsi ea radiator, e sitisang phallo e kholo ea metsi a pholileng mme e eketsa ka potlako khatello tsamaisong ea pholileng. Ha khatello ea ka hare e fihla boemong bo itseng, valve e kholo e khomaretsoeng e tla susumelletseha ka tšohanyetso ho fetola mokhoa oa eona le ho hokahanya ka potlako tsela e kholo ea ho potoloha ha metsi, Ka nako ena, metsi a belang a potlakela ho tlosa sekoahelo sa radiator. Haeba metsi a pholileng a lula a bela nakong ea ho khanna, emisa enjene hang-hang ho etsa hore enjene e tsamaee ka lebelo le tlase ho fihlela mocheso oa metsi o tloaelehile, ebe o koala hore o hlahlojoe. Ha e lumelloe ho kopanya metsi ho pholisa, e le ho thibela mapetsong a likarolo tse amehang ka lebaka la khatello ea maikutlo e ka hare e bakoang ke phapang e kholo ea mocheso. Haeba gasket ea cylinder e chesoa, ka linako tse ling molomo oa tanka ea metsi o ka phalla le ho ntša li-bubble, ho bontša boemo bo belang ba metsi a pholileng. Sena se bakoa haholo ke hore cylinder gasket e chesitsoe kapa hlooho ea cylinder le cylinder liner li na le mapetsong, e leng se etsang hore khase e nang le khatello e phahameng e kene ka har'a baki ea metsi ebe e ntša lipululana tse bohale. Haeba ho phatloha ha cylinder gasket kapa cylinder head ho amana le potoloho ea oli ea lubricating, matheba a oli a tla boela a hlahe ka tanka ea metsi. Mokhoa oa ho hlahloba khase e nang le khatello e phahameng ka har'a silindara e kenang ka har'a sistimi e pholileng: tlosa lebanta la fene ebe u emisa pompo ea metsi. Ha sebatli se matha ka tlase ho lebelo le bohareng, li-bubble li tla bonoa sebakeng sa metsi sa tanka ea metsi 'me ho tla utloahala molumo oa "grunt, grunt", e leng ho lutla ha moea hanyenyane; Haeba pompo ea metsi e sa emisoe, li-bubble li ka bonoa ka ho hlaka 'me molumo oa "ho korotla, ho korotla" o ka utluoa, e leng ho tsoa ha moea ho tebileng; Sekoaelo sa tanka ea metsi se tla tsoa joalo ka pitsa e belang, e leng ho lutla ho hoholo ha moea. Haeba metsi a pholileng a kenngoa ka har'a silindara, mouoane o tla ntšoa phala ea ho ntša metsi nakong ea ho qala 'me mosi o mosoeu o tla ntšoa nakong ea ts'ebetso. Ha ho na ketsahalo e joalo ka mor'a ho fumanoa.
Sephetho sa tlhahlobo: ho na le bothata ka pompo ea metsi. ho lokisa:
Ho tlosa sekala: sebelisa karabelo ea lik'hemik'hale lipakeng tsa asiti kapa alkali le sekala ho hlahisa lintho tse ncha tse qhibilihang ka metsing ho tlosa sekala. Nakong ea ho hloekisa, ho molemo ho sebelisa mokhoa oa microcirculation: pele o hloekisa ka tharollo ea acidic, ebe o hlatsoa ka tharollo ea alkaline bakeng sa neutralization. Nakong ea ho hloekisa, moemeli oa ho theola o potoloha ka tanka ea metsi ka khatello e itseng (ka kakaretso 0.1MPa) bakeng sa 5min Ka mor'a ho hloekisa.

Tokiso ea radiator: Ho lemoha phoso ea radiator hoa lutla. Ka kakaretso ho na le mekhoa e 'meli ea ho lokisa ho lutla ha radiator; Mokhoa oa ho lokisa welding le mokhoa oa ho plugging. Lokisa koloi ka sesebelisoa sa plugging radiator (e leng mokhoa oa ho plugging). Pele o lokisa, hloekisa radiator le ho eketsa 1: 2 Enjene e tla sebetsa hoo e ka bang 80 ℃ bakeng sa 5min Ka mor'a moo, ntša metsi a alkaline, hlatsoa ka metsi a hloekileng, qala enjene, 'me u tšolle metsi ha koloi e futhumatsoa ho fihlela ho 80. ℃. Ebe u tlosa thermostat 'me u fetole moemeli oa plugging ho 1:20 Eketsa metsi ka tekanyo ea, qala enjene, phahamisa mocheso oa metsi ho 80 ~ 85 ℃' me ue boloke bakeng sa 1.0min. Boloka metsi a pholileng a nang le plugging agent ka har'a sistimi e pholileng bakeng sa lihora tse 3 ~ 4 Oh, Molimo oa ka. Radiator e lokisitsoeng e ile ea feta tekong ea ho lutla 'me ea tlisoa ntle le ho lutla.

Tlhokomelo ea pompo ea metsi: pele ho tlhokomelo ea pompo ea metsi, tlosa pompo ea metsi ho tloha enjeneng ebe u e qhaqha. Ha u tlosa pompo ea metsi, qala ka ho bulela sesebelisoa sa ho ntša metsi sa radiator le enjene, kenya se pholileng ka har'a sejana se hloekileng, tlosa liboutu tsa ho lokisa pompo ea metsi le liboutu setulong sa pulley, tlosa sekeno sa metsi le sekoti. hose, 'me u tlose fene le likopano tse ling tse amehang ebe u khanna li-pulleys. Tlosa molamu oa ho lokisa le bolt ea lebanta la koloi, ebe o tlosa pompo ea metsi le gasket ea ho tiisa. Ha o qhaqha pompo ea metsi, qala ka ho lokolla liboutu tsa sekoahelo sa pompo, tlosa sekoahelo sa pompo le ho koala gasket. Ebe u theola pulley ea fene ka se hulang; Ebe u kenya 'mele oa pompo ea metsi ka metsing kapa ka oli ebe u o futhumatsa ho 75 ~ 85 ℃, tlosa pompo ea metsi, kopano ea tiiso ea metsi le kopano ea pompo ea metsi ka pompo ea metsi e nang le disassembler ebe o tobetsa, 'me qetellong u hatelle pompo ea metsi. . Lintlha tsa tlhahlobo ea likarolo tsa pompo ea metsi li kenyelletsa haholo-holo: (1) hore na 'mele oa pompo le setulo sa pulley li tsofetse ebile li senyehile,' me li nkeloe sebaka ha ho hlokahala. Shaft end khoele e senyehile. seal le bakelite pad e feta moeli oa tšebeletso, e tla nkeloa sebaka ke likarolo tse ncha (5) Ha u hlahloba ho apara ha shaft, lekanya ho kheloha ka letšoao la ho daela. Haeba e feta 0.1mm, nkela sebaka ka e ncha. Ela hloko lintlha tse latelang ha u lokisa pompo ea metsi: (1) haeba tiiso ea metsi e tsofetse ebile e kolobisitsoe, e ka batalatsoa ka lesela la emery. Haeba e apere haholo, e lokela ho nkeloa sebaka; Haeba ho e-na le likheo tse mpe holim'a setulo sa tiiso ea metsi, se ka fokotsoa ka sefofane sa sefofane kapa ka lathe (2) Ho lokisoa ha tjheseletsa ho lumelloa ha pompo e na le tšenyo e latelang: bolelele ke 30mm Ka tlase, ha ho na lekhalo le fetelang ho lesoba la ho beleha; Flange e kopantsoeng le hlooho ea silinda e senyehile; Sekoti sa setulo sa tiiso ea oli se senyehile (3) Ho kobeha ha pompo ea pompo ha hoa lokela ho feta 0.03mm, ho seng joalo e tla nkeloa sebaka kapa e lokisoe ka ho hatella ho batang (4) Ho nkela sebaka sa lehare le senyehileng la impeller. Ho kopanya le ho kenya pompo ea metsi.

Tatelano ke ka morao ho disassembly le disassembly. Nakong ea kopano, ela hloko lintlha tsa tekheniki pakeng tsa likarolo tsa mating. Ha u kenya kopano ea pompo ea metsi holim'a enjene, ela hloko lintlha tse latelang: (1) nkela sebaka ka gasket e ncha nakong ea ho kenya (2) Hlahloba le ho lokisa ho tiea ha lebanta. Ka kakaretso, 100N e sebelisoa bohareng ba lebanta Ha khatello e nepahetseng e hatella lebanta, ho kheloha ho tla ba 8 ~ 12mm. Haeba e sa finyelle litlhoko, lokisa boima ba eona (3) Ka mor'a ho kenya pompo ea metsi, kopanya liphaephe tsa metsi tse bonolo tsa tsamaiso ea pholileng, eketsa metsi a pholileng, qala enjene, 'me u hlahlobe ts'ebetso ea pompo ea metsi le metsi a pholileng. tsamaiso e phodileng bakeng sa ho dutla.
Ka tokiso e ka holimo, mocheso o sebetsang oa enjene ea koloi o khutlela ho tloaelehileng.

Pele:Tlhahlobo ea phoso le tlhokomelo ea sistimi ea pholile ea enjine ea koloi (一)

E 'ngoe:Lienjineri tsa diesel li ka baballa mafura ho feta joang? (一)
