Ngā Motuka Paraihe
Koinei ngā momo motuka DC tuku iho e whakamahia ana mō ngā tono taketake kei reira he pūnaha whakahaere tino māmā. Ka whakamahia ēnei i roto i ngā tono kaihoko me ngā tono ahumahi taketake. E whā ngā momo e wehea ana:
1. Whara Raupapa
2. Whara o te Hurihanga
3. Whara Whakakotahi
4. Aukume Tuturu
I roto i ngā motuka DC takai raupapa, ka honoa te takai rotor ki te takai mara. Mā te whakarerekē i te ngaohiko tuku ka āwhina i te whakahaere i te tere. Ka whakamahia ēnei i roto i ngā ararewa, ngā kerēne, me ngā hiki, me ētahi atu.
I roto i ngā motuka DC takai shunt, ka honoa te takai rotor ki te takai mara. Ka taea e ia te tuku taipana teitei ake me te kore e whakaiti i te tere, ā, ka whakanui ake i te ia o te motuka. Nā te taumata waenga o te taipana tīmatanga me te tere pumau, ka whakamahia i roto i ngā kaikawe, ngā huri, ngā horoi korehau, me ētahi atu.
I roto i ngā motuka DC pūhui, ka tāpirihia te polarity o te takai shunt ki tērā o ngā mara raupapa. He teitei te taipana tīmatanga, ā, ka oma pai ahakoa he pai te rerekētanga o te kawenga. Ka whakamahia tēnei i roto i ngā ararewa, i ngā kani porowhita, i ngā papu centrifugal, me ētahi atu.
E ai ki te ingoa, ka whakamahia te aukume tuturu mō te whakahaere tika me te whakaiti i te taipana pērā i te karetao.
Ngā Mōta Kore Paraihe
He māmā ake te hoahoa o ēnei mōta, ā, he roa ake te ora ina whakamahia ki ngā tono teitei ake. He iti noa te tiaki, ā, he tino whai hua. Ka whakamahia ēnei momo mōta i roto i ngā taputapu e whakamahi ana i te whakahaere tere me te tūranga pēnei i ngā pā, ngā pūwero, me ngā papu.
Ngā āhuatanga o te motuka whakaitiiti iti:
1. Kāore e taea te whakamahi i ngā pākahiko i ngā wāhi kāore he hauhautanga.
2. He whakaiti māmā, ka taea te whakarerekē i te ōwehenga whakaroa, ka taea te whakamahi mō te whakaroa.
3. He nui te awhe tere, he nui te taipana.
4. Ka taea te whakarite i te maha o ngā takahuri, ki te hiahiatia, kia rite ki ngā hiahia tūturu.
Ka taea hoki te hoahoa i te motuka whakaheke tere iti kia rite ki ngā whakaritenga motuhake a ngā kiritaki, he rerekē te pou, he tere te ōwehenga o te motuka, ehara i te mea ka taea e ngā kiritaki te whakapai ake i te whai huatanga o te mahi, engari ka penapena hoki i te maha o ngā utu.
Ko te motuka whakaiti iti, te motuka iti DC, te motuka whakaiti taputapu ehara i te mea he iti noa te rahi, he mama, he ngawari te tāutanga, he ngawari te tiaki, he hanganga kiato, he tino iti te oro, he maeneene te mahi, he whānui te whiringa tere putanga, he kaha te whakamahi, he pai te mahi tae atu ki te 95%. Ka roa ake te ora o te mahi, engari ka ārai hoki i te puehu rere me te rere o te wai me te hau o waho ki roto i te motuka.
He māmā noa te tiaki i te mōtini whakaiti iti, te mōtini whakaiti taputapu, he pai te mahi, he pono, he iti te tere pakaru, ā, he pai te whakamahi i ngā rauemi taiao, nā te pūrongo ROHS anō hoki. Kia haumaru ai, kia tau ai te whakamahi a ngā kiritaki. He nui te penapena i ngā utu a ngā kiritaki, ā, ka piki ake te pai o te mahi.
1. He aha te momo paraihe e whakamahia ana i roto i te mōta?
E rua ngā momo paraihe e whakamahia ana e mātou i roto i te motuka: te paraihe whakarewa me te paraihe waro. Ka whiriwhiria e mātou i runga i te Tere, te Iahiko, me ngā whakaritenga mō te roanga o te ora. Mō ngā motuka iti rawa, he paraihe whakarewa anake ā mātou, mō ngā mea nunui, he paraihe waro anake ā mātou. Ki te whakaritea ki ngā paraihe whakarewa, he roa ake te roanga o te ora o ngā paraihe waro nā te mea ka whakaitihia te kakahu o te commutator.
2. He aha ngā taumata haruru o ō koutou motuka, ā, he tino marino ō koutou?
I te nuinga o te wā ka tautuhia e mātou te taumata haruru (dB) i runga i te haruru o te whenua o muri, ā, ka ine i te tawhiti. E rua ngā momo haruru: te haruru mīhini me te haruru hiko. Mō te tuatahi, e pā ana ki te Tere me ngā wāhanga o te motuka. Mō te tuarua, e pā ana ki ngā mura i puta mai i te waku i waenga i ngā paraihe me te commutator. Kāore he motuka marino (kāore he haruru) ā, ko te rerekētanga anake ko te uara dB.
3. Ka taea e koe te tuku rārangi utu?
Mō ā mātou motuka katoa, ka whakaritea kia rite ki ngā whakaritenga rerekē pēnei i te roanga o te ora, te haruru, te hiko, me te pou. Ka rerekē hoki te utu i runga i te rahinga ā-tau. Nō reira, he tino uaua ki a mātou te whakarato i tētahi rārangi utu. Mena ka taea e koe te whakapuaki mai i ō whakaritenga taipitopito me te rahinga ā-tau, ka tirohia e mātou he aha te tuku ka taea e mātou te whakarato.
4. E pai ana koe ki te tuku mai i te whakatau utu mō tēnei motuka?
Mō ā mātou motuka katoa, ka whakaritea kia rite ki ngā whakaritenga rerekē. Ka tukuna atu e mātou te utu i muri tata mai i tō tukunga mai i ō tono me te rahinga ā-tau.
5. He aha te wā ārahi mō ngā tauira, te whakaputa papatipu rānei?
I te nuinga o te wā, e 15-25 ngā rā e hiahiatia ana hei whakaputa tauira; mō te whakaputa papatipu, e 35-40 ngā rā e hiahiatia ana mō te hanga motuka DC, ā, e 45-60 ngā rā mō te hanga motuka taputapu.
6. E hia te utu mō ngā tauira?
Mō ngā tauira iti te utu, kāore e neke atu i te 5 ngā tauira, ka taea e mātou te tuku kore utu, me te utu uta e te kaihoko (mēnā ka taea e ngā kiritaki te tuku mai i tā rātou pūkete kaikawe, te whakarite rānei i te kaikawe hei tiki mai i tā mātou kamupene, kāore he aha ki a mātou). Ā, mō ētahi atu, ka utua e mātou te utu tauira me te utu uta. Ehara i te mea ko tā mātou whāinga he whiwhi moni mā te utu tauira. Mēnā he mea nui, ka taea e mātou te whakahoki moni ina tae mai te ota tuatahi.
7. Ka taea te toro atu ki tā mātou wheketere?
Ae. Engari tēnā koa whakamōhio mai ki a mātou i mua i ētahi rā. Me tirotiro e mātou tā mātou rārangi mahi kia kite ai mēnā kei te wātea mātou i taua wā.
8. He roanga ora tuturu tō te mōtini?
Kāore. He rerekē te roa o te ora mō ngā tauira, ngā rauemi, me ngā āhuatanga whakahaere rerekē pēnei i te pāmahana, te haumākū, te huringa mahi, te mana whakauru, me te hononga o te motuka, te motuka taputapu rānei ki te kawenga, me ētahi atu. Ā, ko te roa o te ora e whakahuatia ana e mātou ko te wā e hurihuri ana te motuka me te kore e mutu, ā, ko te huringa o te Iahiko, te Tere, me te Taipana kei roto i te +/-30% o te uara tīmatanga. Mena ka taea e koe te tohu i ngā whakaritenga taipitopito me ngā āhuatanga mahi, ka arotakehia e mātou kia kitea ko tēhea te mea e tika ana mō ō hiahia.
9. He apiti, he kaihoko rānei tōu i konei?
Kāore ā mātou apiti i tāwāhi, engari ka whakaarohia e mātou tēnā ā muri ake nei. Kei te hiahia tonu mātou ki te mahi tahi me tētahi kamupene, tangata rānei o te ao e hiahia ana ki te noho hei kaihoko ā-rohe hei mahi tahi me ā mātou kiritaki.
10. He aha te momo mōhiohio tawhā e tika ana kia whakaratohia hei aromatawai i tētahi motuka DC?
E mōhio ana tātou, ko ngā āhua rerekē te whakatau i te rahi o te wāhi, ko te tikanga ka taea e ngā rahi rerekē te whakatutuki i te mahi pēnei i ngā uara taipana rerekē. Ko te whakaritenga mahi ko te Ngaohiko mahi, te kawenga whakatauranga, me te Tere whakatauranga, ko te whakaritenga āhua ko te rahi mōrahi o te Tāutanga, te rahi o te pou i waho, me te ahunga o te pito.
Mena he whakaritenga taipitopito anō tā te kiritaki, pērā i te rohenga o nāianei, te taiao mahi, ngā whakaritenga mō te roa o te ora, ngā whakaritenga EMC, me ētahi atu, ka taea hoki e mātou te whakarato i tētahi aromatawai taipitopito me te tika.
He maha ngā painga nui o te hoahoa ahurei o ngā motuka paraihe kore-pōka me ngā motuka paraihe kore-pōka:
1. Te pai o te mahi a te motuka
2. Te kaha ki te tu atu i ngā taiao uaua
3. Te roa o te ora o te motuka
4. Te whakaterenga teitei
5. Te ōwehenga mana/taumaha teitei
6. Te whakahoromata i te pāmahana teitei (e whakaratohia ana e te hoahoa tāke)
7. He tino pai ēnei motuka DC kore paraihe mō te whakamahi i ngā taiao e hiahia ana ki te tika me te roa.
Ngā āhuatanga o te mōtini kapu/kore matua.
