INdibano yeeFasteners ze-Engine ye-Diesel Generators

1.I-cylinder head nut.Xa uqinisa i-nut ye-cylinder head nut, kufuneka iqiniswe inyathelo ngesinyathelo kwi-torque echaziweyo ngamaxesha amaninzi, kwaye uqhubeke ngokomgaqo wokuqala phakathi, emva koko kumacala amabini, kunye nokuwela i-diagonally.Xa udibanisa i-cylinder, kufuneka kwakhona ikhululwe ngokuthe ngcembe ngomyalelo omiselweyo.Ukuba i-nut ye-cylinder head nut iqiniswe ngokungafaniyo okanye ingalingani, iya kubangela ukuba i-cylinder head plane iguqulwe kwaye iguqulwe.Ukuba i-nut igxininiswe ngokugqithiseleyo, ibholithi iya kolulwa kwaye ikhubazeke, kwaye umzimba kunye neentambo ziya konakala.Ukuba i-nut ayiqiniswanga ngokwaneleyo, i-cylinder iya kuvuza umoya, amanzi kunye neoli, kwaye igesi ephezulu yokushisa kwi-cylinder iya kutshisa. isilinda gasket .

2. Flywheel nut.Ngokomzekelo, i-flywheel kunye ne-crankshaft ye-injini ye-diesel ye-S195 idityaniswe ngumgangatho odibeneyo kunye nesitshixo esisicaba.Xa ufaka, i-nut ye-flywheel kufuneka iqiniswe kwaye itshixiwe nge-thrust washer.Ukuba i-flywheel nut ayiqiniswanga ngokuqinileyo, isandi esinkqonkqozayo siya kuveliswa xa injini yedizili isebenza.Kwiimeko ezimandundu, iya konakalisa ikhowuni ye-crankshaft, isike isitshixo, ijije i-crankshaft, kwaye ibangele iingozi ezimandundu.Kwakhona qaphela ukuba iikona ze-thrust washer zinokusongwa kube kanye kuphela.

3. Iibholithi zokudibanisa intonga.Iibhotshi zokudibanisa ezenziwe ngentsimbi ephezulu zithwala impembelelo enkulu ngexesha lomsebenzi, kwaye azikwazi ukutshintshwa ngamabholiti aqhelekileyo.Xa uqiniswa, i-torque kufuneka ibe yinto efanayo, kwaye iibholiti ezimbini zokudibanisa kufuneka ziqiniswe ngokuthe ngcembe kwi-torque echaziweyo kwiinguqu ezininzi, kwaye ekugqibeleni zivaliwe ngocingo lwentsimbi.Ukuba i-torque yokudibanisa intonga yokuqinisa i-torque inkulu kakhulu, ibholithi iya kolulwa kwaye ikhubazeke okanye iphuke, ibangele ingozi ye-cylinder ramming;ukuba i-torque yokudibanisa i-bolt yokuqinisa i-torque incinci kakhulu, i-gap yokuthwala iya kwanda, isandi esinkqonkqozayo kunye nomthwalo wempembelelo kuya kwenzeka ngexesha lomsebenzi, okanye kwenzeke Ingozi ye-bushing ephukile kunye neebholithi zokudibanisa.

4. Iibholithi eziphambili.Ukuchaneka kofakelo lokuthwala okuphambili kufuneka kuqinisekiswe ngaphandle kokukhululeka.Xa uqinisa iibholithi eziphambili (kwi-four-cylinder crankshaft exhaswa ngokupheleleyo), iibheringi ezi-5 eziphambili kufuneka zibe ngolungelelwano oluphakathi, emva koko 2, 4, emva koko 1, 5, kwaye ziqinise ngokulinganayo ukuya kwinqanaba elichaziweyo kwi-2 ukuya kumaxesha ama-3.Umzuzu.Jonga ukuba i-crankshaft ijikeleza ngokuqhelekileyo emva kokuqiniswa ngakunye.Iingozi ezibangelwa i-torque eninzi okanye encinci yokuqinisa i-bolts ye-bolt bearing bolts ngokusisiseko ifana nezo zibangelwa ukugqithisa okugqithisileyo okanye okuncinci kwe-torque ye-rod rod bolts.

5. Ukulinganisela iibholithi zobunzima.Iibholiti zobunzima bokulinganisela kufuneka ziqiniswe kwi-torque echaziweyo kumanyathelo amaninzi ngokulandelelana.Ubunzima bokulinganisela kufuneka bufakwe kwindawo yokuqala, ngaphandle koko iya kulahlekelwa ngumsebenzi wayo wokulinganisela.

6. I-rocker arm seat nut.Kwi-nut ye-rocker arm, kufuneka ihlolwe rhoqo kwaye idibaniswe rhoqo kunye nokugcinwa ngexesha lokusetyenziswa.Ukuba i-nati yesihlalo sengalo ye-rocker ikhululekile, ukukhutshwa kwevalve kuya kwanda, ukuvuleka kwevalve kuya kulibaziseka, ukuvala ivalve kuya kuhambela phambili, kwaye ixesha lokuvula ivalvu liya kufinyezwa, okukhokelela ekuboneleleni komoya okungonelanga kwe-injini ye-diesel, ukukhupha okungahambi kakuhle. , ukuncitshiswa kwamandla, kunye nokunyuka kokusetyenziswa kwamafutha.

7. Isitshixo sentongo yenaliti yamafutha.Xa ufaka i-injector yamafutha, i-nut lock yayo kufuneka iqiniswe kwi-torque echaziweyo.Ngelo xesha, phinda uqinise amaxesha amaninzi, kungekhona ixesha elinye.Ukuba i-nati yokutshixa yesitofu se-fuel iqiniswe kakhulu, i-lock nut iya konakala kwaye ivalve yenaliti iya kuvaleka lula;ukuba iqiniswe ngokukhululekileyo, iya kubangela ukuba i-injector ye-fuel ivuze, uxinzelelo lwe-injection ye-fuel luya kuhla, kwaye i-atomization iya kuba mbi.Ukunyuka kokusetyenziswa kwamafutha.

8. Ivalve yokukhupha ioyile ihleli ngokuqinileyo.Xa ufaka i-valve yokuhambisa i-valve yepompo yesitofu se-fuel, kufuneka kwakhona iqhutywe ngokwetorque echaziweyo.Ukuba isihlalo sevalve ye-oyile siqiniswe kakhulu, umkhono we-plunger uya kuphazamiseka, i-plunger iya kuvinjelwa kwi-sleeve, kwaye i-asembly ye-plunger iya kuguga kwangaphambili, ukusebenza kokutywinwa kuya kuncipha, kwaye amandla aya kuba anele;Ukuba isihlalo esixineneyo sikhululekile kakhulu, siya kubangela ukuba ipompo yokutofa kwe-fuel ivuze i-oyile, uxinzelelo lwe-oyile alunakusekwa, ixesha lokubonelela ngepetroli liphelile, kunye nokunikezelwa kwamafutha kuyancipha, okuchaphazela kakhulu ukusebenza kwe-injini.

9. I-injector pressure plate nut.Xa ufaka indibano ye-injector kwintloko ye-cylinder ye-injini ye-diesel ijenereyitha yedizili , ngaphezu kokususa ukungcola okufana ne-carbon deposits kwi-injector assembly mounting seat, i-plate yoxinzelelo yendibano ye-injector akufanele ifakwe ngokuphambeneyo, kwaye ubukhulu be-gasket yensimbi kufuneka bufaneleke kwaye bungalahleki., Kwakhona nikela ingqalelo kwi-torque yokuqinisa i-nut yeplate yoxinzelelo yendibano ye-injector.Ukuba i-torque yokuqinisa i-nut yeplate yoxinzelelo inkulu kakhulu, i-valve ye-valve ye-injector iya kuphazamiseka, ibangela ukuba i-injector ibe yi-jam, kwaye injini ye-diesel ayiyi kusebenza;ukuba i-torque yokuqinisa incinci kakhulu, i-injector iya kuvuza umoya, okubangela ukungonelanga koxinzelelo lwe-cylinder kunye nobunzima bokuqalisa injini ye-diesel., I-gas ephezulu yokushisa iya kukhawuleza kwaye itshise i-injector fuel.

Ukongeza, xa ufaka i-sliding vane rotor yempompo yokuhambisa kunye noxinzelelo oluphezulu lwemibhobho yeoli edibeneyo kwi-casing yempompo yokuhambisa, i-torque efunekayo nayo iyenziwa.
