I te tau kua hipa, i pāngia tētahi pahi hiko parakore e te pakaru ohorere o te āwhina parai i tētahi wāhanga heke tonu o te Yunnan-Guizhou Plateau. I kitea i roto i te rangahau ko te pūtake o te pakaru o te kaiwhakahaere korehau kotahi i mutu ai te papu korehau, ā, kāore i te rawaka te rokiroki hiko o te tāke korehau iti, ā, tata tonu te puta he aituā nui1. I whakaatuhia e tēnei take ngā mōrearea hoahoa o ngā pūnaha āwhina korehau tuku iho, ā, i meinga hoki te umanga kia tīmata ki te tirotiro anō i te tūranga matua o ngā papu korehau DC moroiti i roto i ngā pūnaha āwhina hiko motuka.

He aha i whakawhirinaki ai ngā waka hiko ki ngā papu korehau moroiti?

I roto i ngā waka wahie tuku iho, ka puta noa te pēhanga kino mai i te pūkaha whakauru miihini, ka whakarato i tētahi puna korehau kore utu mō te pūnaha āwhina parai4. Heoi, kāore he miihini o ngā waka hiko, ā, ki te kore he pūtake korehau, ka tino taumaha te pētera parai - ko te kaha parai o te parai ā-ringa anake kāore e tutuki i ngā whakaritenga haumaru.

I tēnei wā, hepapu korehau DC moroitiko te otinga anake ko te p:

Puku hiko: whakamahia tika te pūtake hiko 12V/24V o te waka, peia te piston, te diaphragm rānei kia tere te neke mā roto i te motuka, ā, tangohia te korehau3;

Whakautu tere:Hei tauira, ka taea e HD-PC3025N te whakatū i te pēhanga kino o te -70kPa i roto i te 1 hēkona hei whakatutuki i ngā hiahia aukati ohorere3;

Te tuku pūngao motuhake:kāore e herea e ngā āhuatanga whakahaere o te miihini, ka taea te mahi ahakoa kei te tū tonu te waka

Me pēhea e taea ai e ngā papu korehau moroiti te wikitoria i ngā arai me te whakatutuki i ngā whakaritenga tino pakari o ngā motuka?

1. Ngā tohu mahi: te taurite i waenga i te korehau me te rere

Te Wero o te Papa Rakau:I te teitei o te 3,000 mita, ka heke te pēhanga hau ki te 70kPa (101kPa i te papatahi). Mena ko te korehau noa iho o te papu he -50kPa, ka heke te pēhanga kino whai hua ki te -20kPa, ka kore rawa he āwhina parai. Nō reira, me whiriwhiri he tauira he korehau ≥-70kPa (pērā i te PC3025N) kia waiho he āputa haumaru.

Te whakaiti i te rere:Mō te papu he 25L/min te rere noa, ka heke pea te rere tuturu ki te 15L/min i muri i te hono i tētahi paipa 1-mita me ngā tuke e rua. I te wā e pēhi tonu ana (pērā i te hekenga roa), ki te kore e ranea te rere, ā, kāore e taea te pupuri i te pēhanga o te tāke korehau, ka tangi te whakaoho pēhi.

 

2.Pono: Te inihua takirua o te pakari me te ārai i te rahunga

Whakamātautau manawanui 1500-hāora:Kua arotauhia a Ruhaizhibo iEVP Pro ki ngā rotor karāhe, ā, ko tōna roanga ora he nui ake i ērā o ngā kaiwhakataetae o te ao.

Hipanga 2: Whakatauritehia te korehau me te rere

Ripanga tirotiro tere (hei tauira mā te whakamahi i ngā tauira noa o Pincheng)

 

Hoahoa pūmana takirua:E rua ngā pūmana whakahaere korehau whakarara e whakamahia ana e te pūnaha hou. Mēnā ka rahua tētahi, ka taea tonu e tētahi te whakahaere i te papu kia mahi, ā, ka kore e rahua te pūmana kotahi.

Rautaki whakaiti kawenga atamai:Ina kitea he turuturu korehau (he rerekētanga pēhanga), ka huri aunoa ki te aratau mahi wā poto hei ārai i te mura o te motuka.

Te urutau ki te taiao: mai i te tino makariri ki te tino makuku

Te ātete ki te kohu wai:Tērā pea ka hongihia e te pūnaha parai te hau makuku, ā, ka waikura ngā papu noa. Heoi, mā te papu korehau PC iti ka taea te "whai kiko i te kohu wai" me te whakamahi i ngā hiri rapa fluoro i roto.

-30℃ tīmatanga makariri:Ka taea tonu e ngā papu motuka kore paraihe (pēnei i te raupapa VML) te urupare tere i ngā pāmahana iti, ka karo i te tūponotanga o te whakapakeketanga o ngā pūnaha waipēhi tuku iho

 

3. Ngā Wero Tūturu: Ngā Ārai me ngā Otinga o te Moroitihoroingā papu

Ahakoa kua pakari te hangarau, e toru tonu ngā āhuatanga nui e pāngia ana e ngā papu moroiti i te wā e whakamahia ana:

Te taupatupatu o te whakapaunga pūngao me te NVH (haruru me te wiri)

He maha ngā wā ka neke atu te mana o ngā papu rere-rahi i te 40W, ā, he nui te mana e pau ana i te mahi tonu (tata ki te 0.5% o te tawhiti o te waka hiko). I taua wā anō, ka tukuna pea te haruru o te motuka ki te kokopiti. Ngā otinga:

Mōta kore paraihe + mana whakahaere auau taurangi: Hei tauira, ka whakaitihia e te raupapa VML te whakamahinga hiko mangere mā te whakahaere tere7;

Taupoki ātete oro + whakaiti wiri ngongo: he otinga noa mā ngā OEM.

Te mōrearea o te wera nui i ngā āhuatanga papatahi me te turuturu

I ngā wāhi papatahi, i te wā rānei e pakaru ai te hiri, ka wera rawa pea te papu nā te roa o te mahi. Ka mutu atamai te papu i te pūmana hou mā te aroturuki i te pikinga pēhanga:

Mena he iti iho i te 8mbar/s te pikinga o te hekenga pēhanga i roto i te 10 hēkona o te whakahaere, ka kiia te pūnaha he noa, ā, ka mutu tonu te papu;

Mena he rerekē te pikinga (te turuturu), ka uru ki te huringa tiaki "mahi 15 hēkona + mutu 10 hēkona"4.

Te kēmu o te wāhi me te utu

Ko te taumaha o ngā papu rere nui (pērā i te PC3025N) he 1kg, ā, he wāhi kei roto i te chassis. Ahakoa ka whakapai ake te pono o te otinga pūmana rua me te tāke korehau nui, ka piki ake te utu mā te 30% pea. Ko te ia o te ahumahi he hoahoa whakauru: Ka whakauruhia e Haizhibo te pūmana ki roto i te tinana papu hei whakaiti i ngā taura waea me ngā atanga6.

 

Te ahunga whakamua: ehara i te "tūranga tārua" noa iho

I te whakahoutanga o te taraiwa atamai, kei te whānui haere ngā mahi a ngā papu korehau moroiti:

Tārua tāpiri mō te taraiwa motuhake i runga ake i te taumata L3:Ina pakaru te pēraki waipēhi hiko, ka tangohia te pūnaha whakakaha korehau hei tautoko ā-mīhini7;

Pūtāhui hau whakatārewatanga hohe:Ka whakamahia e ētahi tauira te papu korehau kotahi hei whakakaha i te puna hau, e tutuki ai te "kotahi papu mō ngā whakamahinga maha"6;

Te tohanga hauwai o te waka pūtau wahie hauwai:E whakamahia ana ngā papu moroiti ātete-waikura i roto i te pūnaha tohanga hauwai hei whakapai ake i te whakamahinga wahie3.

 

Whakatau: Ngā wāhanga matua, engari me arotau te taumata pūnaha

Ka tutuki katoa ngā papu korehau DC iti i ngā hiahia āwhina hiko o ngā waka hiko hou, engari me "tīpakohia kia rite ki ngā tohu":

Ngā waka whānau:He nui te taumata PC3025N (-70kPa, 25L/min) me te pūmana kotahi + 8L tāke korehau8;

Ngā waka arumoni/tauira whenua teitei: me whakamahi papu neke atu i te -80kPa + ngā pūmana takirua + 15L ngā tāke korehau nui, me te whirihora i te aroturukitanga pikinga pēhanga14;

Ngā waka atamai o te heke mai:Ka noho rongonui ngā papu mōtini kore paraihe (pēnei i te VML), me te whai whakaaro ki te whai huatanga, te ata noho me te whakahaere atamai67.

E ai ki te whakaaro o ngā kaihangarau: Ahakoa te kaha o te mahi a te papu kotahi, kāore i te rite te pai ki te mahi tahi a te pūnaha "papu-tāke-kaiwhakahaere-pūoko". I te wā e whiriwhiri ana, kaua e titiro noa ki ngā tawhā ingoa o te papu, engari me manatoko hoki i tōna kaha kawenga me te tikanga urupare hapa i roto i te pūnaha waka katoa - nā te mea, ko ngā mirihekona i waenga i ngā parai te whakatau i te tawhiti haumaru o te ora.

Shenzhen Pincheng Motorhe maha ngā tau o te wheako ki te R&D me te hanga ongā papu korehau moroiti, ā, kua paahitia te tiwhikete motuka IATF 16949, ka taea te whakarato i ngā otinga pai mō te hanga wāhanga motuka.
