Te āhua o te hangarau whakakikorua laser e hanga hou ana i ngā impeller

I roto i te umanga mīhini, he rite ngā impeller ki ngā ngākau kore e ngenge, e akiaki ana i ngā pūnaha uaua mai i ngā miihini rererangi ki ngā papu wai nui. Heoi, ko te pakaru, te waikura, me te ngenge, pērā i te kaiwhakairo o te wā, ka waiho he tohu kore e taea te muru ki runga i ēnei wāhanga hurihuri tere-rahi. Ina tae ngā tikanga whakatika tuku iho ki ō rātou rohe, ka hoatu e te hangarau whakahou matatau e kiia nei ko te "laser cladding" he "ora tuarua" ki ēnei wāhanga matua me tōna tika me te makutu o te pokanga.

I. Te Whakakikoruatanga Taiaho: Te Makutu Whakarewa i te Tauine Iti

Ko te kaupapa matua o te hangarau whakakikorua laser he mahi makutu whakarewa hou e tika ana, e taea ana te whakahaere, e puta ana i roto i ngā wā tauine mirimita. Ka whakamahia he hihi laser kiato-pūngao teitei (te tikanga 10^4~10^6 W/cm²) hei pūtake wera hei hanga tonu i tētahi puna rewa iti ki runga i te mata o te papa impeller kua pakaru. I te wā kotahi, ka werohia ngā paura koranu kua tukuna i mua, i tukuna tahitia rānei o ngā hanganga motuhake (pērā i ngā mea hanga-nikara,-kobalta,-tungsten carbide rānei) ki roto i te puna rewa, ka tutuki ai te hononga whakarewa tere ki te rauemi papa moroiti-rewa. Ko te tukanga katoa, tae atu ki te rewa, te whakaranu, te horapa, me te whakapakeke tere, ka oti i roto i ngā hēkona, i ngā mirimita rānei, ka hanga he paninga matotoru, mahi me te hononga whakarewa kaha ki te papa me te hanganga me ngā āhuatanga tino taea te whakahaere. He rite tēnei ki te "hanga ritenga" me te "whakapiripiri maeneene" i tētahi pukupuku tino kaha ki runga i ngā wāhanga nui o te impeller.

II. Ngā Painga Hangarau: Te Tika, te Pakari, te Ōhanga, me te Atawhai ki te Taiao

Ki te whakatauritea ki ngā tikanga whakatika tuku iho pērā i te whakarewa me te rehu wera, he maha ngā painga o te whakakikorua taiaho i roto i te mara o te hanga anō i te impeller:

1. Tino iti te urunga wera me te whakarerekētanga: He tino kukū te kaha o te taiaho, ā, he tino iti te rohe e pāngia ana e te wera (ko te tikanga he 0.1-1mm), ka taea te pehi i te rerekētanga wera me te ahotea toenga o ngā wāhanga angiangi, ngā wāhanga tika rānei pērā i ngā impeller ki te whānuitanga nui rawa atu, me te whakarite i tō rātou tika āhuahanga.

2. Te kaha o te hononga kāore e taea te whakataurite: He nui ake te kaha o te hononga ā-mata o te hononga whakarewa i tērā o ngā paninga rehu wera, e herea ana mā te miihini, e eke ana ki te 70%-90% o te rauemi turanga, kia mārō ai te paninga, ā, kia kore ai e taka i raro i ngā āhuatanga mahi uaua o te tere teitei me te pēhanga teitei.

3. Te mahi paninga "Ka taea te whakarite": Mā te hoahoa ngāwari i te pūnaha paura koranu, ka taea te whakawhiwhi i ngā āhuatanga ātete-kakahu, ātete-waikura, ātete-haukini pāmahana teitei, ngā āhuatanga hiato rānei ki ngā wāhi motuhake o te impeller, kia tutuki ai te "whakamahi i ngā mea e hiahiatia ana me te hoatu i ngā āhuatanga e hiahiatia ana".

4. Te tino tika o te tukatuka me te kounga o te mata: Ka taea te whakahaere tika i te matotoru o te paninga i waenga i te 0.2-3mm, ā, he papatahi te mata me te iti o te wā tukatuka i muri mai, ā, ka taea te whakatutuki i te āhua tata-kupenga.

5. Ngā painga ōhanga matomato nui: Ko ngā utu whakatika he 30%-50% noa iho o te hanga wāhanga hou, he nui ake te penapena pūngao me ngā rauemi i te 60%, ā, he roa ake te roa o te oranga o te impeller, he tauira ora mō te ōhanga porowhita me ngā ariā whanaketanga tauwhiro.

III. Tukanga Whakatakoto: Mai i te Matawai 3D ki te Whakaotinga Pai

He tukanga hangarau pūnaha, tika hoki te hanga anō i te whakakikorua taiaho impeller:

1. Aromatawai kino me te mamati 3D: Tuatahi, ka whakahaerehia he whakamātautau kore-whakangaro i runga i te impeller tawhito, ā, ka whiwhihia he tauira āhuahanga tika o te wāhi pakaru mā te whakamahi i te matawai 3D.

2. Te Whakamahere Ara me te Hoahoa Tukanga: I runga i te tauira, ka whakamaheretia te ara matawai tino pai o te pane taiaho, ā, ka whakatauhia ngā tawhā tukanga matua pēnei i te mana taiaho ōrite, te tere matawai, me te tere whāngai paura.

3. Te Maimoatanga o mua i te Papa: Ka horoia rawatia te wāhi whakatikatika, ka tangohia ngā poke, ka whakatikatikahia hoki. I ētahi wā ka hiahiatia te whakamahana i mua hei whakaiti i te ahotea wera.

4. Te Whakatakotoranga Atamai me te Aroturuki Tukanga: I raro i te whakahaeretanga o tētahi pūnaha CNC, o tētahi karetao rānei, ka neke te pane taiaho i te ara kua whakaritea, ka whāngai tahi me te tika i te paura, ā, ka aro turukihia te āhua o te puna rewa i te wā tūturu hei whakarite i te kounga pumau.

5. Te Tukatuka-muri me te Aromatawai Mahi: I muri i te whakakikorua, ka taea te mahi whakamahana i te ahotea, me te tāpiri atu ki te miihini e tika ana hei whakahoki mai i te tika o te kōtaha o te mata. Hei whakamutunga, ka whakahaerehia he tirotiro pakari mō ngā āhuatanga, te kore-whakangaro, me te mahi.

IV. Whānautanga Anō: Te Whakapai Ake i te Mahi me te Kimi Anō i te Uara

Ko ngā impeller kua oti te hanga anō i te whakakikorua laser ka eke ki te taumata teitei o te mahi whānui, tae atu ki te eke ki runga ake i ngā hua hou:

Mō te mahi: Ka taea te whakanui ake i te pakeketanga o ngā wāhanga matua (pērā i te taha o te hau e tomo ana me te pito o te mata) ki te 2-3 ngā wā i tērā o te rauemi turanga, ā, ka roa ake te roa o te ātete kakahu mā te 3-10 ngā wā; ka eke te ātete waikura me te ātete cavitation ki tētahi pikinga kounga. Hei tauira, i muri i te whakakikoruatia o te impeller o te papu wai o te teihana hiko ki tētahi koranu e ahu mai ana i te cobalt, ka piki ake tōna roanga ātete cavitation mā te neke atu i te 5 ngā wā.

Taumata āhuahanga: Ka whakaora tika, ka arotau rānei i te hoahoa taketake, kia pai ai te whai huatanga o te waipēhi me te mahi aerodynamic.

Taumata ōhanga: Ka tino whakaiti i ngā utu tiaki taputapu me te hoko wāhanga e manawapa ana, ka whakaiti i ngā ngaronga wā kore mahi i whakamaheretia.

Taumata rautaki: He mea nui rawa atu tēnei hangarau hei whakarite i te whakahaere haumaru mō te wā roa o ngā taputapu matua i roto i ngā rāngai matua pēnei i te hiko, te matū hinu, te hanga kaipuke, me te rererangi, me te whakaiti i te whakawhirinaki ki ngā wāhanga e manawapa ana kawemai.

Whakamutunga

Mai i ngā pūwāhi hononga whakarewa uaua ki te hanga anō i ngā impeller, he tino whakaata te hangarau whakakikorua laser i te kotahitanga o te "tika" me te "kaha" i roto i te hanga hou. Ehara i te mea he tikanga whakatika noa iho, engari he huarahi whakarerekētanga mō te whakarei ake i te mahi me te tauira hanga matomato. Mā te whakaurunga hohonu o ngā hangarau atamai me te mamati me te tukatuka laser, ka tino tuhia e te whakakikorua laser ētahi atu pakiwaitara ahumahi i roto i te mara whānui o te hanga anō i ngā taputapu teitei.
