Mhete yepistoni.
Mhete yepiston inoshandiswa kuisa gomba repiston mukati memhete yesimbi, mhete yepiston yakakamurwa kuita mhando mbiri: mhete yekumanikidza uye mhete yemafuta. Mhete yekumanikidza inogona kushandiswa kuvhara gasi rinobvira mukamuri rinopisa; Mhete yemafuta inoshandiswa kukwenya mafuta akawandisa kubva mucylinder. Mhete yepiston imhando yemhete yesimbi ine deformation yakakura yekunze, iyo inounganidzwa muprofile uye gomba rayo reannular rinoenderana. Mhete dzepiston dzinodzokororwa uye dzinotenderera dzinoshandisa musiyano wekumanikidzwa kwegasi kana mvura kuti dzigadzire chisimbiso pakati pedenderedzwa rekunze remhete necylinder uye rimwe divi remhete negomba remhete.
Mashandisirwo ekushandisa
Mhete dzepiston dzinoshandiswa zvakanyanya mumichina yakasiyana-siyana yemagetsi, senge mainjini esteam, mainjini edhiziri, mainjini epeturu, macompressor, ma hydraulic presses, nezvimwewo, zvinoshandiswa zvakanyanya mumotokari, zvitima, ngarava, mayacht nezvimwewo. Kazhinji, mhete yepiston inoiswa mu ring groove yepiston, uye iyo nepiston, silinda liner, silinda musoro nezvimwe zvikamu zvekamuri kuti zviite basa.
Mhete yepiston ndiyo chinhu chikuru chiri mukati meinjini yemafuta, iyo necylinder, piston, rusvingo rwesilinda pamwe chete kuti vapedzise chisimbiso chegasi remafuta. Injini dzemotokari dzinoshandiswa kazhinji dzine mhando mbiri dzeinjini dzedhiziri nepeturu, nekuda kwekushanda kwadzo kwakasiyana kwemafuta, kushandiswa kwemhete dzepiston hakuna kufanana, mhete dzepiston dzepakutanga dzinoumbwa nekukanda, asi nekufambira mberi kwetekinoroji, mhete dzepiston dzesimbi dzakagadzirwa nesimba guru, uye nekushanda kweinjini, zvinodiwa zvakatipoteredza zvinoramba zvichivandudzika, mhando dzakasiyana dzekushandiswa kwepamusoro kwekurapa pamusoro, dzakadai sekupfapfaidza kwemafuta, electroplating, chrome plating, nezvimwewo. Kuisa gasi mu nitriding, physical deposition, surface coating, zinc manganese phosphating treatment, nezvimwewo, zvinovandudza zvikuru mashandiro emhete yepiston.
Basa remhete yepiston rinosanganisira kuvhara, kudzora mafuta (kudzora mafuta), kupinza kupisa (kutamisa kupisa), kutungamira (kutsigira) mabasa mana. Kuvhara: zvinoreva kuvhara gasi, usarega gasi remukamuri rekupisa richibuda kuenda kucrankcase, kubuda kwegasi kunodzorwa zvishoma, kuvandudza kushanda zvakanaka kwekupisa. Kubuda kwemhepo hakungoderedzi simba reinjini chete, asiwo kunoita kuti mafuta aderere, iro riri basa guru remhete yegasi; Gadzirisa mafuta (kudzora mafuta): mafuta akawandisa anozora pamadziro esilinda anokweshwa, uye madziro esilinda akafukidzwa nefirimu remafuta rakatetepa kuti ive nechokwadi chekuti silinda nepiston neringi zvinozora zvakanaka, iro riri basa guru remhete yemafuta. Muinjini dzemazuva ano dzinomhanya zvakanyanya, kutarisisa kwakakosha kunopihwa pabasa refirimu remafuta repiston; Kufambisa kupisa: kupisa kwepiston kunopfuudzwa kucylinder liner kuburikidza nemhete yepiston, ndiko kuti, mhedzisiro yekutonhora. Zvichienderana neruzivo rwakavimbika, 70 ~ 80% yekupisa kunogamuchirwa nepamusoro pepiston yepiston isina kutonhora kunoparadzirwa nepamhete yepiston kuenda kumadziro esirinda, uye 30 ~ 40% yepiston inotonhorera inoparadzirwa nepamhete yepiston kuenda kumadziro esirinda; Rutsigiro: Mhete yepiston inochengetedza piston musisirinda, inodzivirira kusangana zvakananga pakati pepiston nemadziro esirinda, inoita kuti piston ifambe zvakanaka, inoderedza kuramba kwekukweshana, uye inodzivirira piston kuti isadonhedze sirinda. Kazhinji, piston yeinjini yepeturu inoshandisa mhete mbiri dzegasi nemhete imwe yemafuta, nepo injini yedhiziri inowanzo shandisa mhete mbiri dzeoiri nemhete imwe yegasi.
Kuzivikanwa kwakanaka nekwakaipa
Nzvimbo yekushanda yeringi yepiston haifanirwe kunge iine mavanga, mavanga, kukwenya, sirinda yekunze uye nzvimbo dzekumusoro nedzepasi dzinofanira kunge dzakagadziriswa, kutsauka kwe curvature hakufanirwe kupfuura 0.02-0.04 mm, kudzika kweringi iri mu groove hakufanirwe kudarika 0.15-0.25 mm, uye kusimba uye kuchena kweringi yepiston zvinosangana nezvinodiwa. Pamusoro pezvo, tinofanirawo kutarisa kuyerera kwechiedza cheringi yepiston, kureva kuti, rin'i yepiston yakati sandara mu sirinda, isa rambi diki pasi peringi yepiston, isa chidzitiro chechiedza pamusoro, uye wobva waona mukana wekubuda kwechiedza pakati peringi yepiston nemadziro e sirinda, izvo zvinoratidza kana kubatana pakati peringi yepiston nemadziro e sirinda kwakanaka. Mumamiriro ezvinhu akajairwa, musono wekubuda kwechiedza weringi yepiston wakayerwa negeji yeukobvu haufanirwe kudarika 0.03 mm. Kureba kwemusono wekubuda kwechiedza chinoenderera mberi hakufanirwe kupfuura 1/3 yedhayamita yesirindiro, kureba kwenzvimbo dzakawanda dzekubuda kwechiedza hakufanirwe kupfuura 1/3 yedhayamita yesirindiro, uye kureba kwese kwenzvimbo dzakawanda dzekubuda kwechiedza hakufanirwe kudarika 1/2 yedhayamita yesirindiro, zvikasadaro, inofanira kutsiviwa. Piston ring marking GB/T 1149.1-94 inotaura kuti mapiston ring ese anodiwa kuti ave negwara rekukwirisa anofanira kunge akaiswa chiratidzo kudivi repamusoro, kureva kuti, kudivi riri pedyo nekamuri rekupisa. Mapiston akaiswa chiratidzo kudivi repamusoro anosanganisira: cone ring, inner chamfer, outer cutting table ring, nose ring, wedge ring uye oil ring inoda gwara rekuisirwa, uye divi repamusoro rerindi rakaiswa chiratidzo.
