Valve akara n'elu egweri
Nke mbụ, na-egweri ụkpụrụ na ngwá ọrụ ndị bụ isi
(I) Ụkpụrụ ndị bụ isi:
Bụ usoro nhazi agwụcha, nwere ike ime ka akụkụ ahụ nweta izi ezi nke akụkụ dị elu, nkenke geometric na imecha elu, mana enweghị ike imeziwanye ọnọdụ n'etiti oke elu.
Egweri, ngwá ọrụ na elu workpiece dabara ọnụ, n'etiti na-ejuputa abrasives, mgbe ngwá ọrụ n'akụkụ nkwonkwo elu, mgbagwoju mgbatị n'etiti akụkụ abụọ nke abrasive grits elu slide ma ọ bụ Rolling, akụkụ nke abrasive na-agbakwunyere ma ọ bụ sessile na ngwá ọrụ elu, na ebipụ site workpiece elu bụ nnọọ mkpa oyi akwa nke metal, na convex elu na workpiece bụ mbụ egweri, nke nta nke nta nweta ezigbo elu chọrọ.
Iji mee ka elu egweri edo, ikwu ngagharị ụzọ nke ọ bụla n'ókè na workpiece ka egweri ngwá ọrụ kwesịrị ịbụ otu ihe dị ka o kwere mee, otú ntụziaka nke ikwu ngagharị kwesịrị ịgbanwe mgbe niile.
Na ngwa ngwa na-egweri ije, na elu arụmọrụ, ma ọ bụrụ na ọ dị oke elu, ọ ga-eme ka workpiece na-ekpo ọkụ na-emetụta geometric ziri ezi. N'otu oge ahụ, anyị kwesịrị ịṅa ntị ka ị ghara itinye nrụgide dị ukwuu n'elu, ma ọ bụghị ya, ọ ga-emekwa ka okpomọkụ.
N'ihi na egweri bụ ezigbo nhazi, na ọnwụ ego bụ nnọọ obere, otú na nwere ike hụ na-ewepụ nhazi trace nke ikpeazụ usoro, premise nke na-agbazi workpiece geometry njehie, nta na-egweri ohere, mma.
(2) Ngwa egweri
Ihe eji eme ihe na-egweri kwesịrị izute abụọ ndị a: ① dị mfe iji tinye irighiri ihe abrasive ② nwere ike ịnọgide na-enwe nhazi geometric nke ngwa egweri ruo ogologo oge. Ya mere, n'ozuzu ojiji nke nro ihe karịa workpiece na-eme nnyocha ngwaọrụ, na-ejikarị isi awọ nkedo ígwè.
Abrasive bụ ngwakọta nke ihe na mmiri na-ekpo ọkụ. Ihe ndị a na-ejikarị eme ihe bụ corundum (alumina), silicon carbide, boron carbide, chromium oxide, iron oxide na diamond ntụ ntụ, akwa abrasive na-adịghị ahụkebe mgbe ejiri ya.
A na-eji mmiri na-egweri emezi ihe na-ekpo ọkụ, ma na-arụ ọrụ nke mmanye, oyi na oxidation.
Abụọ, valvụ akara n'elu egweri
(a) iji aka egweri
Iji ntuziaka na-egweri dị mfe, ma obere arụmọrụ, adịghị mma, adabara obere ụlọ ọrụ na nrụzi.
1. Ntuziaka ntuziaka nke akara akara nke valvụ ahụ
A na-etinye iji oghere oghere nke ogige diski ekara egweri n'elu akara akara nke oghere valvụ ahụ, mgbe ahụ, a na-eji ogologo aka nwere isi square na-ebugharị efere egweri maka mmegharị ahụ. Enwere onye isi kọlụm ubi ma ọ bụ mee ka efere na-eduzi okpomọkụ na efere egweri iji gbochie ngwá ọrụ egweri imeghe elu akara.
Tupu egweri, a ga-ehichapụ ngwá ọrụ egweri, kpuchie ya na oyi akwa nke abrasive, na ngwá ọrụ egweri kwesịrị ịkwado n'elu akara akara, buru ụzọ tụgharịa elekere 180 ° wee na-atụgharị 90 Celsius, ya mere ugboro ugboro, ṅaa ntị na uwe na ike kwesịrị ekwesị. mgbe ị na-egweri, ma na-agbakwunye abrasive mgbe niile.
2, valvụ efere, valvụ diski na akụkụ ndị ọzọ akara n'elu egweri
Iji na-egweri efere maka ntuziaka egweri, mbụ na efere evenly ntekwasa na a oyi akwa nke egweri gị n'ụlọnga, na workpiece na-mmasị efere, n'ihi na otu akụkụ ime adiana na-eme linear ije ma ọ bụ ọgụgụ 8 ije.
