Ukulungisa valve kwi Moped "Alpha". Moped "Alpha" - izithombe, izici

Kungani ukuba ulungise valve kwi Moped "Alpha"? Injini ye FMB Moped 139 ifakwe isikhathi ne camshaft ise ikhanda isilinda. I valve eliqhutshwa esebenzisa rocker izingalo. Phakathi nomsebenzi we-valve injini ahlupheke ukunwetshwa ezishisayo, ngakho-ke, inikeza igebe encane phakathi ingalo rocker futhi valve, okuyinto ivala isikhala ukunwetshwa ezishisayo. Anokususwa ikani umonakalo injini sina asanele noma ngokweqile. Umphumela ongemuhle kwezikhala okungajwayelekile kancane kancane aqoqana futhi kungabangela ezishile valve esihlalweni ekubhujisweni, kwehle kokucindezelwa okweqile kanye ukusonteka isikhathi ISIZINDA ezibalulekile. Ukulungisa valve kwi Moped "Alpha" izikhathi eziningana phakathi nenkathi okumele yenziwe. Uma kungenjalo amisiwe izikhala ezishisayo ingavela isici ongqongqozayo umsindo uma injini iyasebenza, okuyilona elisebenzayo futhi isizathu valve ukulungiswa.

Injini ye Moped "Alpha» FMB 139

Ezine-unhlangothi injini FMB 139 ingenye izinzuzo main ukuthi Moped "Alpha". Photo libonisa injini ngenhla. Lena enokwethenjelwa kakhulu futhi ukonga injini ukukhanya isisindo. umthamo wayo kungaba isukela 49 kuya 125 cm. Cc., Futhi ukushuba kungenzeka kusuka 5 kuya ku-8 hp Ukulungiswa yenjini angase abe ehlukile ivolumu uMbhalo. Ungakwazi ekhaya ufake inguqulo ucishe enamandla eqenjini isilinda. Injini ifakwe gearbox emine esiteji. Ngenhla kuba Moped carburetor "Alpha".

Engine igesi ukusatshalaliswa indlela 139 FMB

Engine Valve igiya FMB 139 ifakwe camshaft ngokufanele ekhanda isilinda. Amaphayiphu ahlelwe thwi futhi ezimise-V futhi iqhutshwa esebenzisa rocker izingalo, nakho kuqhutshwa esebenzisa Cams we camshaft. Lolu hlelo kakhulu efana isikhathi "Moskvich" 412, kuphela uMbhalo ingenye kuphela, valve - amabili.

I camshaft kuqhutshwa esebenzisa uchungechunge yokudlulisela. It, yona, eliqhutshwa pinion elisoGwini generator Rotor-eksisi okuyinto eksisi ka ukujikeleza crankshaft.

Prevention isikhathi nemiphumela yokwehluleka

Zonke izici ze-FMB 139 Engine Isikhathi Siyadinga gqwa njalo degree kwabo bafake. Welulekela isikhathi uchungechunge nezingxabano yayo isici ukuwohloka kungaholela zokugwema ukuphuka yayo, okuyinto kuzodinga ukulungisa ngempela enzima elihlobene ne isidingo ukususa Rotor generator, noma disassembly ukufaka esikhundleni lonke crankcase uwoyela futha amagiya. Ngaphezu kwalokho, isikhathi uchungechunge zokugwema ukuphuka kungadala ukusonteka of valve, okuyinto kuzodinga esikhundleni kanye amapuleti ethi awafike ku Saddles valve entsha. Ukwehluleka izakhi isikhathi umuntu kungabangela eziningi nezinye umonakalo.

Izimpawu izilungiselelo valve ayilungile

Uma izikhala ukuthungela makhulu kakhulu, lokho kungase kubangele isici ongqongqozayo noma ikhala ukuthi kwenzeka uma injini iyasebenza. kokucindezelwa ukulahlekelwa kungaba futhi umphumela ongaqondile ayilungile izilungiselelo valve. umphumela ongaqondile okungafanele ukulungiswa umphini kungenzeka ukwanda petrol kanti ekunciphiseni amandla ngenxa depressurization valve, kanye nokulahlekelwa synchronism wokusebenza, lapho ama-valve ukusebenza iqala ekuqaleni noma kamuva esuka imijikelezo piston.

I-apharathasi begodu ethi awafike valve

Valve on Moped "Alpha" zenziwa ngendlela efanayo njengoba ngoba imoto. Sinenkosi ipuleti Intonga ukuthi elongates ngenxa ukunwetshwa ezishisayo ngesikhatsi operation injini. Jwayelekile imvume kumelwe libe 0.05 mm. Lapho Ukushisa we imvume ezishisayo ubalekela cishe ngokuphelele valve. valve amapuleti sealingly uhlale sehhashi, futhi imiphetho zabo kufanele lapped ngokuphelele emaphethelweni esihlalweni. Ethi awafike valve Moped akahlukile imisebenzi afanayo ezinjinini zezimoto nasezintweni kwenziwa ngokusebenzisa nokunamathisela efanayo ngesandla noma ngomshini, usebenzisa sokuprakthiza. Ukuze ususe valve kusukela ekhanda isilinda FMB 139 isebenzisa Puller ekhethekile ijabulise.

imiphumela enqabayo ezisuka kusukela izilungiselelo valve ayilungile

A pusher ijoka kumele ucindezele valve, kodwa okwandisa igebe ezishisayo uqala ukushaya ku-valve, okubangela ukukhala isici ongqongqozayo ngesikhatsi operation injini. Lokhu kungaholela bafake yashesha yenjini izakhi ezibalulekile. I disc umphini iqala ukushaya esihlalweni, okubangela ukubukeka ukukhubazeka onqenqemeni esihlalweni futhi valve. Emazingeni aphezulu emaphethelweni kwamanzi ezindaweni deformations encane uqale ashiswe, siyeke ukulingana uvalwe komunye nomunye. yobunzima Lost, red-hot omlilo amagesi ifohle futhi ababhubhise ebusweni valve imiphetho nakakhulu. Valve okweqile kwenzeka futhi, kwezinye izimo baqale ukuqhekeka futhi isihlalo sehhashi, futhi ichopho, izingcezwana ezincane ewa ekamelweni amandla omlilo, ukuhwaya piston nodonga isilinda.

In the ukungabikho igebe ezishisayo ngokuyinhloko ukuhlupheka qeda valve. Umjikelezo wokusebenza kwalo enwetshiwe, okuholela okweqile kanye ukuncibilika imiphetho yayo. Uma valve onomfutho, kungase kuphele ngisho ukuthi kuvaliwe. Ngo ukusebenza ngokuvamile kwenzeka ukwandisa usayizi igebe ezishisayo, okuyinto isizathu isidingo ukuhlolwa njalo lokhu ubuningi.

Ukulungisa valve kwi Moped "Alpha"

Amaphayiphu ku FMB motor 139 ngokufanele nangaphezulu ikhanda isilinda. Ukuze kufinyelele kuwo, udinga uyasikrufulula isivalo. Ukulungisa valve kwi Moped akudingi ukususwa lonke ikhanda. Kodwa kubalulekile ukubeka uMbhalo iphuzu efile. Ngenxa yale njongo isivalo has a generator Rotor ukuvulwa phezulu ivaliwe, esikhundleni salokho, ikhava plastic. Unscrewing ke, ungabona umzimba ugesi, eyenza ephawulwe. Nge khahlela ukuziqalela generator kungaba ngobumnene uphendukisa Rotor kuze kuze ilebuli "T". Ukusebenza efanayo engenziwa usebenzisa isondo. I Moped kumele agqoke footrest emaphakathi, faka igiya lesine futhi ngobumnene ujike isondo kuze kubonakala ilebuli "T" emgodini emehlweni.

Ukuze ulawule ngokunembile inqubo, ungakwazi ukukhipha ikhava kusukela block isikhathi inkanyezi, esemgwaqweni ngakwesokunxele isilinda ikhanda. Kulesi lenkanyezi ilebula ngesimo iphuzu. Uma lolu phawu kuzoba isikhundla ezikwesokunxele, kuzosho iphuzu efile. ukulungiswa valve kwi Moped "okuzenzakalelayo" kungase kwenziwe ngemva kokumiswa uMbhalo iphuzu efile. Kuyadingeka ukuba athambise nut ukukhiya push induku. Khona-ke kudingeka ibenze uphenyo ka 0.05 mm phakathi pusher kanye stem valve, qinisa induku push ngesandla, kodwa ukuze kwenziwe uphenyo kungenziwa kususwe. Khona-ke, isikhundla pusher kuyadingeka ukuze uqinise nut detent.
