Egweri bụ usoro mmecha a na-ejikarị eme ihe maka mkpuchi elu nke valves na usoro nrụpụta. Egweri nwere ike ime ka elu valvụ ahụ na-ekpuchi elu nweta oke nha anya, ọdịdị ọdịdị geometric na ịdị nro n'elu, mana ọ nweghị ike imeziwanye ọnọdụ ọnọdụ n'etiti elu nke mkpuchi ahụ. The akụkụ ziri ezi nke ala valvụ akara elu na-abụkarị 0.001 ~ 0.003mm; ọdịdị ọdịdị geometric (dị ka enweghị isi) bụ 0.001mm; Ntugharị elu bụ 0.1 ~ 0.008.
Ụkpụrụ bụ isi nke ịchichi ihe mkpuchi elu na-agụnye akụkụ ise: usoro ịkụcha ihe, mmegharị ahụ, ngwa ngwa ngwa ngwa, nrụgide na-egweri na inye ohere.
1. Usoro egweri
A na-ejikọta ngwá ọrụ na-egweri na elu nke mgbanaka akara nke ọma, na ngwá ọrụ egweri na-eme ka ihe mgbagwoju anya na-emegharị ihe n'akụkụ elu nkwonkwo. A na-etinye abrasives n'etiti ngwá ọrụ na-akpụ akpụ na elu nke mgbanaka akara. Mgbe ngwá ọrụ ntanye na elu nke mgbanaka akara na-agagharị n'ebe ibe ha nọ, akụkụ nke mkpụrụ osisi abrasive na abrasive ga-adaba ma ọ bụ na-atụgharị n'etiti ihe mkpuchi na elu nke mgbanaka akara. oyi akwa ígwè. N'elu elu nke mgbanaka akara na-ebu ụzọ pụọ, ma jiri nwayọọ nwayọọ nweta geometry achọrọ.
Egweri abụghị naanị usoro abrasives na ọla, kamakwa ọ na-arụ ọrụ kemịkal. Agriiz na abrasive nwere ike ịmepụta ihe nkiri oxide n'elu ka a na-edozi ya, si otú a na-eme ka usoro nsị dị ngwa ngwa.
2 . ije ije
Mgbe ngwá ọrụ egweri na elu nke mgbanaka akara na-agagharị n'ebe ibe ha nọ, nchikota nke ụzọ mgbanaka nke ebe ọ bụla n'elu mgbanaka akara na ngwá ọrụ egweri kwesịrị ịbụ otu. Ọzọkwa, ntụziaka nke mmegharị nke ikwu kwesịrị ịdị na-agbanwe mgbe niile. Mgbanwe na-agbanwe agbanwe nke ntụziaka nke mmegharị ahụ mgbe niile na-egbochi ọka ọ bụla abrasive ka ọ ghara ịmegharị trajectory nke ya n'elu nke mgbanaka akara, ka ọ ghara ime ka ọ bụrụ ihe na-eyi ihe doro anya ma mee ka ọkpụkpụ dị elu nke mgbanaka akara. Tụkwasị na nke ahụ, mgbanwe mgbanwe na-aga n'ihu nke ntụziaka nke mmegharị ahụ enweghị ike ime ka abrasive na-ekesa nke ọma, nke mere na ígwè dị n'elu nke mgbanaka akara nwere ike belata nke ọma.
Ọ bụ ezie na mmegharị ahụ na-agbagwoju anya na ntụziaka nke mmegharị ahụ na-agbanwe nke ukwuu, a na-eme mmegharị ahụ mgbe niile n'akụkụ njikọ nke ihe eji eme ihe na elu nke mgbanaka akara. Ma ọ bụ iji aka egweri ma ọ bụ igwe egweri, ọdịdị geometric ziri ezi nke mgbanaka akara akara na-emetụta nke ọma n'ụdị geometric ziri ezi nke ngwa egweri na mmegharị ahụ.
3. egweri ọsọ
Na-agba ọsọ na-egweri ije, ka ịrụ ọrụ nke ọma na-egweri. The egweri ọsọ bụ ngwa ngwa, ọzọ abrasive ahụ na-agafe n'elu nke workpiece kwa nkeji oge, na ihe metal na-ebipụ.
The egweri ọsọ na-abụkarị 10 ~ 240m / min. N'ihi na workpieces chọrọ elu egweri nkenke, na-egweri ọsọ n'ozuzu adịghị gafere 30m / min. Ọsọ ọsọ nke mkpuchi mkpuchi nke valvụ ahụ na-ejikọta ihe dị n'elu mkpuchi. The egweri ọsọ nke akara elu nke ọla kọpa na nkedo ígwè bụ 10 ~ 45m / min; na akara elu nke siri ike ígwè na ike alloy bụ 25 ~ 80m / min; The sealing elu nke austenitic igwe anaghị agba nchara 10 ~ 25m / min.
4. egweri nrụgide
Ịrụ ọrụ nke igwe nri na-abawanye na mmụba nke nrụgide na-egweri, na nrụgide egweri ekwesịghị ịdị elu, n'ozuzu 0.01-0.4MPa.
Mgbe egweri elu akara nke nkedo ígwè, ọla kọpa na austenitic igwe anaghị agba nchara, na egweri nsogbu bụ 0.1 ~ 0.3MPa; The akara elu nke siri ike ígwè na ike alloy bụ 0.15 ~ 0.4MPa. Were uru ka ukwuu maka egweri siri ike yana ọnụ ahịa dị nta maka ichicha nke ọma.
5. Nkwenye egweri
Ebe ọ bụ na egweri bụ usoro ịmecha, ọnụ ọgụgụ nke ịkpụ dị ntakịrị. Ogo nke nrịba ihe egweri na-adabere na nzi ezi machining na nhụsianya elu nke usoro gara aga. N'okpuru nhazi nke ijide n'aka na mwepụ nke nhazi nhazi nke usoro gara aga na imezi njehie geometric nke mgbanaka akara ahụ, obere ihe nkwụnye ihe nkedo, ka mma.
Ebe a na-emechi ihe kwesịrị ịbụ nke ọma n'ala tupu egweri ya. Mgbe egweri nke ọma, enwere ike ịlapu elu mkpuchi ahụ ozugbo, yana obere ohere ichikota bụ: ohere nke dayameta bụ 0.008 ~ 0.020mm; Ụgwọ ụgbọ elu bụ 0.006 ~ 0.015mm. Were obere uru mgbe iji ntuziaka na-egweri ma ọ bụ ihe ike siri ike dị elu, ma were nnukwu uru mgbe igwe igwe ma ọ bụ ihe ike siri ike dị ala.
Elu akara nke valvụ ahụ adịghị mma ka ọ bụrụ ala na nhazi ya, ya mere enwere ike iji ntụgharị dị mma mee ihe. Mgbe emechara tụgharịa, akara n'elu ga-abụ ihe siri ike n'ala tupu emecha, na ụgbọ elu ohere bụ 0.012 ~ 0.050mm.
