⑤ Sealant
Sealant bụ ụdị ihe eji emechi ihe ọhụrụ na ndozi nke injin ụgbọ ala ọgbara ọhụrụ. Ọdịdị ya na mmepe ya na-enye ọnọdụ dị mma maka imeziwanye nkà na ụzụ akara ma dozie "nyocha atọ" nke engines. E nwere ọtụtụ ụdị ihe mkpuchi, nke a pụrụ itinye n'akụkụ dị iche iche nke ụgbọ ala ahụ. Igwe ụgbọ ala na-ejikarị akara na-abụghị bonded (nke a na-akpọ gasket mmiri mmiri). Ọ bụ ihe mmiri viscous nwere ngwakọta polymer dị ka matriks. Mgbe mkpuchi gasịrị, a na-emepụta akwa akwa akwa akwa, kwụsiri ike na nke na-aga n'ihu na-ejikọta ya na nkwonkwo nke akụkụ ahụ, ma nwee ike mejupụta ịda mbà n'obi na elu nke nkwonkwo. n'ime oghere. Enwere ike iji ihe mkpuchi ahụ naanị ma ọ bụ jikọtara ya na gaskets ha na mkpuchi valvụ engine, pan mmanụ, mkpuchi valvụ, wdg, a pụkwara iji ya naanị ya n'okpuru mkpuchi mkpuchi ikpeazụ nke crankshaft, yana nkwụnye mmanụ mmanụ na oghere. mmanụ plọg. were gabazie.

2 Ọtụtụ okwu kwesịrị ịkwụ ụgwọ na mmezi nke akara engine

① The ochie sealing gasket enweghị ike ijikwa ọzọ
A na-etinye gaskets mkpuchi nke engine n'etiti akụkụ nke akụkụ abụọ ahụ. Mgbe gaskets na-abịakọrọ, ha dakọtara na microscopic unevenness nke elu nke akụkụ na-egwu a akara ọrụ. Ya mere, oge ọ bụla a na-edobe engine ahụ, a ga-edochi gasket ọhụrụ, ma ọ bụghị ya, nkwụsị ga-emerịrị.

② Njikọ nkwonkwo nke akụkụ ahụ kwesịrị ịdị larịị ma dị ọcha
Tupu ịwụnye gasket ọhụrụ, hụ na nkwonkwo nkwonkwo nke akụkụ ahụ dị ọcha na enweghị unyi, ma n'otu oge ahụ, lelee ma ọ bụrụ na akụkụ nke akụkụ ahụ na-agbagọ, ma ọ bụrụ na e nwere oghere convex na oghere njikọ njikọ, wdg. ., na ekwesịrị idozi ya ma ọ bụrụ na ọ dị mkpa. Mmetụta akara nke gasket nwere ike ịrụ ọrụ n'ụzọ zuru ezu mgbe nkwonkwo elu nke akụkụ ahụ dị larịị, dị ọcha na enweghị agha.

③ The engine gasket kwesịrị idobe nke ọma na echekwara
Tupu eji ya, ekwesịrị ịchekwa ya kpamkpam n'ime igbe mbụ, a pụghịkwa ikpokọta ya n'ụzọ akaghị aka ka ọ gbadaa na nchikota, na e kwesịghịkwado ya na nko.

④ All eriri njikọ kwesịrị ịdị ọcha na adịghị emebi emebi
A ga-ewepụ unyi dị na eriri nke bolts ma ọ bụ screw oghere site na eriri ma ọ bụ ịpị; A ga-ewepụ unyi dị na ala nke oghere ndị ahụ na mgbata na ikuku abịakọrọ; eri na aluminom alloy cylinder isi ma ọ bụ cylinder ahụ kwesịrị jupụta na sealant , iji gbochie gas ịbanye n'ime jaket mmiri.

⑤ Usoro ijikọ kwesịrị ịbụ ezi uche
Maka elu nkwonkwo jikọtara ya na ọtụtụ bolts, otu bolt ma ọ bụ nut ekwesịghị ịkụnye ya n'otu oge, ma a ga-agbatị ọtụtụ ugboro iji gbochie nrụrụ nke akụkụ ahụ na-emetụta arụmọrụ akara. Bolts na mkpụrụ dị n'elu ebe nkwonkwo dị mkpa kwesịrị ịgbatị dị ka usoro a kapịrị ọnụ si dị ma na-eme ka ike sie ike.
a. Usoro tightening nke isi cylinder kwesịrị ịbụ nke ziri ezi. Mgbe ị na-eme ka ihe mkpuchi isi cylinder sie ike, a ga-agbasarịrị ya n'ụzọ symmetrically site na etiti ruo n'akụkụ anọ, ma ọ bụ dị ka eserese usoro ihe siri ike nke onye nrụpụta nyere.
b. Ụzọ mkpirisi nke mkpuchi isi cylinder kwesịrị ịbụ nke ziri ezi. N'okpuru ọnọdụ nkịtị, bolt tightening torque value kwesịrị tightening na uru a kapịrị ọnụ n'ime oge 3, na nkesa torque nke ugboro 3 bụ 1 /4, 1/2 na ọnụ ahịa torque akọwapụtara. A ga-eme bolts isi cylinder nwere ihe pụrụ iche dị ka iwu ndị nrụpụta si dị. Dịka ọmụmaatụ, Hongqi CA 7200 sedan chọrọ uru torque nke 61N·m maka oge mbụ, 88N·m maka oge nke abụọ, yana ntụgharị 90 ° maka oge nke atọ.
c. Aluminom alloy cylinder isi, ebe ọ bụ na ọnụọgụ mgbasawanye ya dị ukwuu karịa nke bolts, a ga-ejigide bolts na ọnọdụ oyi. Ihe nkedo cylinder isi ihe nkedo kwesịrị imechi okpukpu abụọ, ya bụ, mgbe ụgbọ ala oyi na-eme ka ọ dị ike, na engine na-ekpo ọkụ wee kpoo ya otu ugboro.
d. Ekwesịrị iji igwe na-asa mmiri dị larịị, nke na-asa mmiri ekwesịghị ịdị na-akpakọrịta kpọmkwem na pan mmanụ. Mgbe ị na-eme ka ịghasa ahụ sie ike, a ga-agbatị ya nke ọma na ugboro abụọ site na etiti ruo na nsọtụ abụọ, na ike ịgbatị ahụ na-abụkarị 2ON·m-3ON·m. Oke oke ike ga-emebi ite mmanụ ma mebie arụmọrụ akara.

⑥ Ojiji sealant ziri ezi
a. Ihe mmetụta nrụgide mmanụ plọg mmanụ niile na ihe mmetụta ihe mmetụta mmanụ mmanụ kwesịrị iji mkpuchi mkpuchi kpuchie ya mgbe ị na-etinye ya.
b. Cork osisi gaskets ekwesịghị ịbụ ntekwasa na sealant, ma ọ bụghị adụ osisi gaskets ga-adị mfe mebiri emebi; E kwesịghị ikpuchi ihe mkpuchi na cylinder gaskets, oriri na iyuzucha ọtụtụ gaskets, spark plọg gaskets, carburetor gaskets, wdg.
c. Mgbe ị na-etinye sealant, a ga-etinye ya n'otu n'otu n'otu akụkụ, na enweghị nkwụsị nke gluu n'etiti, ma ọ bụghị ya, a ga-enwe nkwụsị na gluu gbajiri agbaji.
d. Mgbe ị na-ekpuchi elu nke akụkụ abụọ ahụ na mkpuchi naanị, oke kachasị n'etiti oghere abụọ ahụ kwesịrị ịbụ ihe na-erughị ma ọ bụ hà nhata 0.1mm, ma ọ bụghị ya, a ga-agbakwunye gasket.

⑦ Mgbe etinyere akụkụ niile ma jikọta ya dị ka achọrọ, ma ọ bụrụ na a ka nwere ihe ngosi "mpụpụ atọ", nsogbu ahụ na-adaberekarị na àgwà nke gasket n'onwe ya.
N'oge a, a ga-enyochaghachi gasket ma jiri nke ọhụrụ dochie ya.

Ọ bụrụhaala na ahọpụtara ihe mkpuchi ahụ n'ụzọ ezi uche dị na ya na a na-eleba anya na ọtụtụ nsogbu nke nrụzi mkpuchi, enwere ike ịchịkwa ihe omume "mpụpụ atọ" nke injin ụgbọ ala nke ọma.
