Mhosva yekuongorora uye kuchengetedza kwemotokari injini kutonhora system (二)
2021-08-11
Inovira uye inoshanduka kuita yakajairika chete mushure mekugadzira mvura inotonhorera. Analysis uye kuongororwa:
(1) Injini painopisa kamwe kamwe panguva yekutyaira, tanga watarisa kusimba kweiyo ammeter. Kana iyo ammeter isingaratidzi kuchaja kana ichiwedzera throttle, uye geji tsono inongoburitswa ne 3 ~ 5A Nenguva isipi ichidzokera ku "0" chinzvimbo chinoratidza kuti bhandi re fan rakatyoka. Kana ammeter ichiratidza kuchaja, vhara injini uye bata radiator uye injini nemaoko. Kana tembiricha yejinjini yakanyanyisa uye tembiricha yeradiator yakaderera, inoratidza kuti pombi yemvura shaft uye impeller yakasununguka, ichikanganisa kutenderera kwemvura inotonhorera; Kana mutsauko wetembiricha pakati peinjini neredhiyeta usina kukura, tarisa kana paine yakakomba yekudonha kwemvura muinotonhora system. Mushure mekuona, kutonhora kwejini kwakanyanyisa uye kupisa kwe radiator kwakaderera, uye pombi yemvura ine matambudziko;
(2) Tembiricha yemvura inotonhorera inokwira nekukurumidza pakutanga kwekutanga, zvichikonzera kufashaira kwemvura inotonhorera. Iyo huru vharuvhu ye-multi-system thermostat inodonha uye inonamirwa mukati mepombi yekupinza mvura yeradiator, iyo inotadzisa kutenderera kukuru kwemvura inotonhorera uye nekukurumidza kuwedzera kudzvanywa muhurongwa hwekutonhora. Kana kumanikidzwa kwemukati kunosvika kune imwe nhanho, iyo yakanamatira huru vharafu inongoerekana yakurudzira kushandura iyo yakatarisa uye nekukurumidza inobatanidza nzira huru yemvura inotenderera, Panguva ino, mvura inofashaira inokurumidza kubvisa chivharo che radiator. Kana mvura inotonhodza ichigara ichifashaira paunenge uchityaira, misa injini nekukasira kuti injini imhanye nekumhanya kwakaderera kusvika tembiricha yemvura yakajairika, wobva wavhara kuti iongororwe. Hazvibvumirwi kusanganisa mvura kuti itonhorere pasi, kuitira kudzivirira kutsemuka kwezvikamu zvakakosha nekuda kwekushushikana kwemukati kunokonzerwa nekusiyana kwakanyanya kwekushisa. Kana iyo cylinder gasket yakapiswa kunze, dzimwe nguva tangi yemvura muromo inogona kupfachukira uye inoburitsa mabhubhu, ichiratidza kufashaira kwemvura inotonhorera. Izvi zvinonyanya kuitika nokuti cylinder gasket inopiswa kunze kana kuti cylinder head uye cylinder liner zvine makatsemuka, izvo zvinoita kuti gasi repamusoro-soro ripinde mubhachi remvura uye rinobudisa mabhubhu anotyisa. Kana kutsemuka kwe cylinder gasket kana cylinder head kwakabatana nerubricating oil circuit, mafuta mavara achaonekwawo mutangi remvura. Nzira yekuongorora ye-high-pressure gasi mucylinder channeling mugadziriro yekutonhora: bvisa bhandi re fan uye misa pombi yemvura. Kana iyo yekutanga ichimhanya pasi pepakati kumhanya, mabhubhu achaonekwa painopinza yemvura yetangi remvura uye "grunt, grunt" ruzha ruchanzwika, inova kushoma kwemhepo kubuda; Kana pombi yemvura isina kumira, mabhubhu anogona kuoneka zvakajeka uye kurira kwe "grunt, grunt" inogona kunzwika, iyo inove yakakomba mhepo inodonha; Chifukidziro chetangi remvura chinoputika sepoto iri kufashaira, inova inodenha mhepo. Kana mvura inotonhodza ikasvetwa mucylinder, chiutsi chinoburitswa kubva papombi yekupopota panguva yekutanga uye utsi huchena huchaburitswa panguva yekushanda. Iko hakuna chiitiko chakadaro mushure mekuonekwa.

Muedzo mhedzisiro: pane dambudziko nepombi yemvura. kugadzirisa:
Kubvisa Scale: shandisa kemikari inoitwa pakati peasidhi kana alkali zvinhu uye chikero kugadzira zvinhu zvitsva zvinonyungudika nemvura kubvisa chikero. Panguva yekuchenesa, zviri nani kutora micro circulation nzira: tanga wachenesa ne acidic solution, wozosuka nealkaline solution yekusagadzikana. Panguva yekuchenesa, mumiriri wekudzikisa anotenderera mutangi remvura pane imwe dzvinyiriro (kazhinji 0.1MPa) ye5min Mushure mekuchenesa.
Radiator kugadzirisa: redhiyeta kutadza kuona kuri kubuda. Pane kazhinji nzira mbiri dzekugadzirisa radiator kuvuza; Welding kugadzirisa nzira uye plugging nzira. Gadzirisa mota neradiyeta plugging agent (i.e. plugging nzira). Usati wagadziriswa, chenesa radiator uye wedzera 1: 2 Injini ichashandiswa pa80 ℃ ye5min Mushure, dhonza mvura yealkaline, sukurudza nemvura yakachena, tanga injini, uye dhonza mvura kana mota ichidziya kusvika makumi masere. ℃. Wobva wabvisa iyo thermostat uye gadzirisa iyo plugging agent ku1:20 Wedzera mvura muchikamu che, tanga injini, simudza tembiricha yemvura kusvika 80 ~ 85 ℃ uye chengeta iyo 1.0min. Chengetedza mvura inotonhorera ine plugging agent mune inotonhorera system kwe3 ~ 4 maawa Oh, Mwari wangu. Iyo radiator yakagadziridzwa yakapfuura bvunzo yekuvuza uye yakaunzwa isina kuvuza.
Kugadziriswa kwepombi yemvura: usati wagadzirisa pombi yemvura, bvisa pombi yemvura kubva mujini uye uiparadzanise. Paunenge uchibvisa pombi yemvura, tanga wabatidza switch yemvura yeradiator neinjini, isa chinotonhodza mumudziyo wakachena, bvisa mabhaudhi epombi yemvura nemabhaudhi pachigaro chepulley, bvisa pombi yemvura nekubuda nayo. hose, uye bvisa fan uye mamwe magungano akakodzera uye kutyaira pulleys. Bvisa tsvimbo yekugadzirisa uye bhaudhi yebhandi rekutyaira, uye wozobvisa pombi yemvura uye kuvhara gasket. Paunenge uchibvisa pombi yemvura, tanga wasunungura mabhaudhi epombi, bvisa chivharo chepombi uye kuvhara gasket. Zvadaro dhonza pasi feni pulley nemudhonza; Wobva waisa muviri wepombi yemvura mumvura kana mafuta uye woipisa kusvika 75 ~ 85 ℃, bvisa pombi yemvura inotakura, seal seal yemvura uye musangano wepombi yemvura ine pombi inotakura disassembler uye wozodzvanya, wozopedzisira waburitsa pombi yemvura. . Zvinhu zvekuongorora zvezvikamu zvepombi yemvura zvinonyanya zvinosanganisira: (1) kana pombi yepombi nechigaro chepulley zvakasakara uye kukuvara, uye kuzvitsiva kana zvichidikanwa (2) Kana shaft yepombi yakagonya, kana magazini yakasakara, uye kuti shaft end shinda yakuvadzwa (3) Kana blade iri pane impeller yakatyoka uye kana gomba reshaft rakapfekwa zvakanyanya (4) Kana dhigirii remvura richipera. chisimbiso uye bakelite pad inodarika muganho webasa, ichatsiviwa nezvikamu zvitsva (5) Paunenge uchitarisa kupfeka kweshaft, kuyera kutsauka nechiratidzo chedhiya. Kana ichipfuura 0.1mm, tsiva fani yacho neitsva. Chenjerera kune zvinotevera pakugadzirisa pombi yemvura: (1) kana chisimbiso chemvura chakasakara uye chakagerwa, chinogona kupepetwa nemucheka we emery. Kana yakapfekwa zvakanyanya, inofanira kutsiviwa; Kana pane zvigwere zvakakasharara pachisimbiso chemvura chigaro, chinogona kuchekwa nendege reamer kana palathe (2) Welding kugadzirisa inobvumidzwa kana pombi ine kukuvara kunotevera: kureba kuri 30mm Pazasi, hapana kutsemuka kunosvika kusvika. gomba rekubereka; Iyo flange yakasanganiswa ne cylinder musoro yakakuvadzwa; Gomba rechigaro chechisimbiso chemafuta rakakuvadzwa (3) Kukotama kwepombi shaft hakufaniri kudarika 0.03mm, zvikasadaro ichatsiviwa kana kugadziridzwa nekutsikirira kunotonhora (4) Tsiva iyo yakakuvadzwa impeller blade. Kusangana uye kuiswa kwepombi yemvura.
Kutevedzana ndiko kudzosera kumashure kwe disassembly uye disassembly. Panguva yegungano, teerera kune zvigadzirwa zvehunyanzvi pakati pezvikamu zvekusangana. Paunenge uchiisa musangano wepombi yemvura pane injini, teerera kune zvinotevera: (1) shandura negasket itsva panguva yekuisa (2) Tarisa uye gadzirisa kusimba kwebhanhire. Kazhinji, 100N inoshandiswa pakati pebhanhire Kana kudzvinyirirwa kwekodzero kunotsikirira pasi bhanhire, kukanganisa kuchava 8 ~ 12mm. Kana iyo isingaite zvinodiwa, gadzirisa kusimba kwayo (3) Mushure mekugadzwa kwepombi yemvura, batanidza mapaipi emvura akapfava eiyo inotonhorera, wedzera mvura inotonhorera, tanga injini, uye tarisa kushanda kwepombi yemvura uye inotonhorera system yekudonha.
Kuburikidza nekugadzirisa kuri pamusoro, tembiricha yekushandisa yeinjini yemotokari inodzokera kune yakajairika.
