Disassembly yepiston yekubatanidza tsvimbo boka
Kana mota yako yakanyura mumvura, ndapota usamanikidza kupisa, nekuti kana mvura yakakwira kupfuura injini yemhepo, mvura inopinda zvakananga mucylinder, ichigadzira musanganiswa wemvura yakapfava, gasi rinogona kuomeswa, uye mvura. haigoni kumanikidzwa. Kana injini iri mumvura uye crankshaft inosundidzira tsvimbo yekubatanidza kuti inomesa ikananga kwepiston, mvura haigone kudzvanywa. Mushure mokunge tsvimbo yekubatanidza ichiiswa pasi pekudzivisa kwemvura, ichakanganisa uye inokotama, kana kunyange kuputsa.
1. Chengetedzo ye disassembly
① Iyo huruva yekunze inofanira kubviswa isati yasassembly, nyatso cherechedza uye rangarira nzvimbo uye chiratidzo chechikamu chimwe nechimwe chakabviswa.
② Usati waburitsa piston yekubatanidza tsvimbo, nhanho yekabhoni pachikamu chepamusoro checylinder liner inofanira kukweshwa kudzivirira kukuvadza piston nepiston mhete.
③ Kana uchitora piston yekubatanidza tsvimbo boka, tsvimbo yemapuranga inogona kusundirwa kunze. Mushure mokunge boka rekubatanidza piston rabudiswa kunze, chivharo chekubatanidza tsvimbo, tile uye yekubatanidza tsvimbo yebhaudhi inofanira kuiswa mu situ pakarepo.
④ Kana uchibvisa cylinder liner, cylinder liner puller kana tsvimbo yehuni inofanira kushandiswa. Usarove cylinder liner zvakananga nesimbi tsvimbo.
⑤ Iyo yakabviswa piston mhete inofanira kuiswa munhevedzano. Cylinder gaskets uye mapepa gaskets anofanira kuchengetwa zvakanaka.
⑥ Kana zvichidikanwa kubvisa vhiri rinobhururuka, chinodhonza flywheel chinofanira kushandiswa, uye mabhaudhi maviri eanodhonza anofanira kumonyororwa achichinjana, uye zvinorambidzwa zvachose kushandisa sando yeruoko kunyudza zvakasimba. Paunenge uchibvisa iyo flywheel, kuitira kudzivirira iyo flywheel yakasununguka kamwe kamwe kudonha kukuvara, usakurumidza kubvisa iyo flywheel nati mushure mekusunungura.
2. Kuiswa kwekuchengetedza
① Zvikamu zvinofanirwa kucheneswa usati waiswa, tarisa kubvumidzwa, uye kuita ongororo yehunyanzvi. Zvikamu zvisingaite zvinodiwa nehunyanzvi zvinofanirwa kugadziriswa kana kutsiviwa.
② Gomba rekamuri yevortex kumusoro kwepiston uye gomba remafuta ekuzora pamucheto mudiki wetsvimbo yekubatanidza inofanira kunge iri parutivi rumwe, uye inofanira kunge iri kumusoro.
③ Paunenge uchitsiva iyo silinda liner nyowani, silinda seti inofanirwa kuiswa mugomba rekuisa isati yaisa mhete yekudzivirira mvura, tarisa kureba kwemuviri unobhururuka, uye inogona kuiswa zviri pamutemo mushure mekusangana nezvinodiwa. Silinda liner yeS195 injini yedhiziri inogona kutenderedzwa 90 ° kana kupfeka kusiri kukuru. Silinda liner yeS195 injini yedhiziri haigone kushandurwa.
④ Kana uchiisa mhete yepiston, chenjerera kuti usakwenya piston uye kutyora mhete yepiston. Iyo chrome-plated mhete ichaiswa mune yekutanga ring groove. Kana mupendero wemukati wemhete yechipiri neyechitatu ine grooves, grooves inofanira kuitwa kumusoro; Kana kumucheto kwekunze kune grooves, grooves inofanira kuitwa pasi. Chamfer pamucheto wekunze werin'i yemafuta inofanira kunge iri kumusoro. Iwo maviri uye matatu gasi zvindori zvechina-mhete piston zvindori zvindori, uye divi rine "dhipatimendi" kana "┬" paringi rinofanira kunge riri kumusoro kana rakaiswa. Paunenge uchiisa mhete yemafuta yakasanganiswa, mhete yekugadzira inofanira kutanga yaiswa, uye migumo yayo miviri haifanirwe kupindirana uye kukotama, wozoisa inotevera mhete yakatsetseka, kuitira kuti inodzvanya ringin ring kuvhura, wozoisa waveform ring uye pamusoro pezvindori zviviri zvakati sandara. Paunenge uchishandisa zvindori zvepiston zvina kana zvindori zvemafuta zvakasanganiswa, mhete yemafuta inofanira kutakurwa mugororo rekutanga remafuta. Iyo piston yekubatanidza tsvimbo yekubatanidza inofanira kuputirwa nemafuta matsva pamusoro pepiston uye silinda liner isati yarodha muhumburumbira. Paunenge uchirodha, kuvhurwa kwemhete yepiston kunofanirwa kudzika 120 ° kubva kune mumwe nemumwe, uye dzivirira gomba razvino eddy uye piston pini gomba, dzivirira nzvimbo yepiston pasi pekumanikidzwa kwedivi. Zvishandiso zvakakosha (masimbi esimbi) anofanirwa kushandiswa kana mhete yepiston yaiswa mucylinder liner.
Mushure mekushandiswa, mabheji makuru ekuruboshwe nekurudyi haabvumirwi kutsiviwa, uye matanda epamusoro nepamusoro ekubatanidza tsvimbo haigoni kuiswa zvisina kururama. Iyo yekubatanidza tsvimbo tile inofanira kunge ine imwe tightness mushure mekutsikirira muchigaro chetairi, uye zvishoma kumusoro kupfuura ndege yechigaro chetairi.
6. Mutsara wepumburu ye cylinder pad inofanira kutarisana ne-cylinder head side, uye maburi anofanira kuenzaniswa nemakomba emuviri. Paunenge uchiomesa cylinder musoro nati, inofanirwa kusungirirwa zvakaenzana mu diagonal cross sections zvinoenderana neinotarwa torque. Kunyanya kusununguka kuri nyore kudonhedza nekupisa humburumbira pad; Kunyanya kusimba zviri nyore kuita kuti silinda pad irasikike, zvichikonzera kutsvedza kwebhaudhi kana screw hole. Tsiva iyo humburumbira gasket itsva, uye simbisa silinda musoro nati zvakare mushure me20h yekushanda.
