I roto i te rerenga maitai o te ahumahi hou, he rite ngā kerēni ki ngā ringa mīhini kore e ngenge, e pikau ana i te mahi taumaha o te whakahaere rauemi. Hei "pū io" o tēnei mīhini nui, he hononga tika te mahi a ngā mowhiti paheke taura ki te whai huatanga o te mahi me te haumaru o te kerēni. I te aroaro o te whānuitanga o ngā hua mowhiti paheke kei te mākete, me pēhea te whiriwhiri i te "hoa koura" tika mō te kerēni? Mā tēnei tuhinga, ka āwhina mātou i a koe ki te whakautu i ngā pātai i roto i tō hinengaro.
Ⅰ. Whakamāramahia ngā āhuatanga mahi o ngā kerēne, ā, whakatauhia te ahunga urutau
He maha ngā mema o te whānau kerēni, ā, he "tino mahi" anō ā ngā kerēni gantry, kerēni piriti, me ngā kerēni pourewa. He rite ngā kerēni gantry ki ngā "tino maitai" i ngā wāhi mahi o ngā tauranga me ngā whare putunga nui, e haereere ana i waenga i ngā ipu me ngā utanga i ia rā. Ehara i te mea me aro noa rātou ki ngā kawenga taumaha o te rere me te taunga auau, engari me ātete hoki ki te mimiti o te rehu tote me te puehu e haria ana e te hau moana, me te "iriiri" o ngā ua ohorere; ko ngā kerēni pourewa te "Optimus Prime" i runga i te papa hanga. I te piki haere tonu o ngā papa, me mahi pinepine rātou i ngā mahi hiki, hurihuri me te whakakorikori, ā, ka haere tahi ia hurihuri me te wiri nui me te pānga. Mā ēnei āhuatanga mahi ahurei ka whakatau he rerekē rawa ngā whakaritenga mō te taumata tiaki, te kaha kawe kawenga me te pakari o te mowhiti paheke taura. Nō reira, i mua i te whiriwhiri i te mowhiti paheke, he rite te rangahau whānui me te taipitopito o te taiao mahi o te kerēni, te auau mahi, me ngā āhuatanga kawenga ki te tuhi i tētahi "mahere whakatere" tika mō ngā kōwhiringa e whai ake nei.
Ⅱ. Arotahi ki ngā tawhā hiko, kia mau tonu te haumaru o te au me te ngaohiko
(I) Ngā tawhā o nāianei
Ko te kaha kawe iahiko te tohu hiko matua o te mowhiti paheke. I te nuinga o te wā, mō ngā kereini hiko iti, ka taea e te iahiko whakatauranga o te 50-100A te whakatutuki i ngā whakaritenga mahi taketake; i te mea mō ngā kereini gantry tauranga nui, nā te nui o te mana katoa o te motuka hiki, te motuka e rere ana i te trolley, me te motuka e rere ana i te trolley, ko te iahiko whakatauranga mowhiti paheke e hiahiatia ana ko te 200-630A. Mena ka nui ake te iahiko mahi tuturu o te mowhiti paheke i te uara whakatauranga mō te wā roa, ka piki ake te wera o ngā wāhanga kawe hiko. Hei tauira, mō ngā paraihe parahi, ina neke ake te pāmahana i te 80℃, ka heke te kawe hiko, ka piki ake te ātete pa, ā, ka puta pea he mura hiko, ka tere ake te kakahu o ngā paraihe me ngā mowhiti kawe hiko.
(II) Ngā tawhā ngaohiko
Ko ngā ngaohiko hiko noa mō ngā kerēni ko 380V, 400V, 690V, me ētahi atu. I roto i te taiao whatunga hiko ahumahi, ka rerekē te ngaohiko i roto i te whānuitanga o te ±10%, nō reira me whānui te urutau o te mowhiti paheke ki te ngaohiko. Hei tauira, he nui te pokanoa o ngā kerēni e whakamahia ana i roto i te umanga whakarewa i roto i te taiao mahi. Me whiriwhiri he mowhiti paheke me te ngaohiko whakatauranga o te 690V me te mahi tiaki ngaru, ka taea te tu atu i te ru ngaohiko whakatauranga 1.2 ngā wā tere kia pai ai te tuku hiko.
(III) Te ātete ārai me te ngaohiko tu atu
Ko te ātete ārai e whakaata ana i te mahi ārai hiko o te mowhiti paheke, e hiahiatia ana kia neke atu i te 500MΩ; me tutuki te whakamātautau ngaohiko ātete ki te ngaohiko auau mana o te 1500V, ā, kaua e pakaru, e mura rānei mō te 1 meneti hei whakarite i te mahi haumaru o te mowhiti paheke i roto i te taiao hiko uaua.
Ⅲ. Te whakakotahitanga o ngā whakaritenga mō te mowhiti paheke me te taura
He rite te whanaungatanga i waenga i te mowhiti paheke o te rīra taura me te taura ki te "taputapu me te mekameka". Mā te mahi tahi tata anake ka taea te whakatutuki i te mahi whai hua. I te wā e whiriwhiri ana i te mowhiti paheke, ko te diameter o waho o te taura, te maha o ngā matua me te rauemi ngā mea matua e whakaarohia ana. Me 1-2mm te nui ake o te kōhao o te mowhiti paheke i te diameter o waho o te taura kia maeneene ai te tāutanga o te taura; ka whakatauhia te maha o ngā awa i runga i te maha o ngā matua taura, ā, ko te tikanga he 1-2 ngā awa e toe ana.
Mō ngā taura whakahaere maha-matua, mēnā ko te horahanga whakawhiti matua he 0.75-2.5mm², me whakahaere te ātete pa o te mowhiti paheke i roto i te 50mΩ kia kore ai e hē te tuku tohu. Hei tauira, he taura YC taumaha-mahi kua hipokina ki te rapa, he maha ngā wā ka whakamahia mō te hononga motuka kerēni. Ko tōna radius piko he 6-8 ngā wā o te diameter o waho o te taura. Nō reira, me taurite ki te mowhiti paheke me te paraihe tino ngāwari. Ka mau tonu te pēhanga pa o te paraihe ki te 0.15-0.25N/cm² kia iti ai te pakaru i waenga i te taura me te mowhiti paheke.
Ⅳ. Whakapakari i te taumata tiaki me te whakapai ake i te urutau ki te taiao
He maha ngā wero i roto i te taiao mahi o ngā kerēni, ā, he mea noa te pāmahana teitei, te pāmahana iti, te haumākū, te puehu, te urunga mai o te hau waikura me ētahi atu āhuatanga. Ko ēnei āhuatanga taiao kino, pērā i ngā "hoariri kāore e kitea", ka whakararu tonu i te mahi me te roa o te ora o ngā mowhiti paheke taura. Nō reira, ko te whiriwhiri i tētahi mowhiti paheke me te taumata tiaki e tika ana kia rite ki te taiao mahi tūturu he rite ki te whakakakahu i tētahi "pūeru tiaki" pakari mō te mowhiti paheke.
I ngā tauranga o waho e pupuhi ana ngā hau moana me ngā ngaru, me whiriwhiri he mowhiti paheke me te taumata tiaki IP67, ka taea te ārai katoa i te puehu kei uru, ā, ka taea te rumaki ki roto i te wai hohonu 1 mita mō te 30 meneti me te kore e uru te wai; i roto i ngā mira maitai wera me ngā whare whakarewa, ka taea e te pāmahana o te awheawhe te eke ki runga ake i te 60℃, ā, me whiriwhiri he mowhiti paheke ātete pāmahana teitei, ko te awhe pāmahana whakahaere ko -40℃-120℃, ā, ka whakamahia he rauemi hiri rapa silicone, he ātete tawhito pai rawa atu.
V. Aromatawai hōhonu o ngā āhuatanga ā-pūkaha hei whakarite kia pumau te mahi
(I) Te tere me te taipana
Ina oma te kerēni, ka rerekē te tere o te mowhiti paheke. Ko te tere o te mowhiti paheke o te kerēni piriti he 10-30 r/min; ko te tere o te mowhiti paheke e peia ana e te tikanga whiu o te kerēni pourewa ka eke ki te 50-80 r/min. I te wā e whiriwhiri ana i te mowhiti paheke, me 20% teitei ake te tere whakatauranga i te tere whakahaere tuturu kia pai ai te haumaru. I taua wā anō, me whai whakaaro ki te taipana tīmatanga. I te nuinga o te wā, me kaua e neke ake i te 1.5 ngā wā o te taipana whakatauranga te taipana tīmatanga o te mowhiti paheke kia kore ai e pakaru te hanganga o roto nā te taipana nui rawa i te wā e tīmata ana.
(II) Te roa o te ora me te ātete ki te kakahu
Ka inehia te roa o te ora o te mowhiti paheke mā te maha o ngā hurihanga, ā, ka taea e ngā hua kounga teitei te eke ki te 50 miriona ki te 100 miriona wā. Ka whakamahia e ōna peera o roto ngā peera pōro awaawa hohonu tino tika me te kawenga hihiri kua whakatauria o te 10-50kN; ko te nuinga o te rauemi paraihe he mea hanga ki te koranu waro-karāpiti, ā, ka whakahaeretia tōna pakeke ki te 40-60HA te pakeke o te takutai hei whakarite i te ātete pai ki te kakahu me te whakaiti i ngā huringa tiaki.
(III) Ngā tawhā wiri me te ru
I ngā papa hangahanga, ka taea e te tere o te wiri e puta mai ana i ngā kerēne pourewa te eke ki te 5 - 10m/s² i te wā e whakahaerehia ana, ā, ka taea e te tere o te wiri te eke ki te 50 - 100m/s². Me paahitia e ngā mowhiti paheke ngā whakamātautau wiri (auau 10 - 500Hz, kaha 0.75mm) me ngā whakamātautau wiri (ngaru haurua-sine, tere tere tihi 50g, roanga 11ms) kia mau ai te mahi i raro i ngā āhuatanga mahi uaua.
Ⅵ. Kōwhiria he kaihanga mowhiti paheke me ngā waitohu kounga teitei me ngā āheinga ratonga muri-hoko
I roto i te moana mākete o ngā mowhiti paheke taura, he rerekē te kounga o te hua. Ko te whiriwhiri i tētahi waitohu pono he rite ki te kimi i tētahi whare rama kanapa i te moana whānui. He ingoa pai tō Ingiant Technology, he nui ōna wheako me te kaha hangarau ngaio i roto i te umanga mowhiti paheke raupapa DHK038, ā, he maha ngā wā he paerewa whakaputa tino pakari me te pūnaha whakahaere kounga katoa.
