Ko te whakarite i ngā papa keri raro whenua e whakawhirinaki nui ana ki te keri toka tere, tika, me te auau. Ko te keri poka puhoi, hē rānei ka whakaroa tika i te whanaketanga o te kauhanga, te hanganga o ngā papa me ngā wā whakaputa konganuku. Mō ngā tīma keri hou e hiahia ana ki te whakahaere i ngā rerenga mahi o te papa, ko teYT29Ahaute wiri toka waewae-hauKa tukuna he mahi keri tere-tiketike pono e whakapoto ana i ngā huringa whakarite mō ngā tūnga keri, ā, ka whakapai ake i te whai huatanga o te whakaritenga maina whānui.
Neke atu i te rua tekau tau o te wheako ngaio e arotahi ana kikeri tokaI roto i te hanga mīhini, kua arotauhia e tā mātou wheketere te keri toka waewae-hau YT29A hei whakaoti i ngā uauatanga roa o ngā mahi keri whenua. Kua hangaia tēnei taputapu keri kua whakapaitia kia tū atu ki ngā āhuatanga mahi whenua uaua, e tuku ana i te pumau kaha ake, te tere keri tere ake me te iti ake o ngā reiti rahunga ki te whakataurite ki te tikanga.ngā mahi keri maina.
He taputapu taumaha te YT29Awiri toka hauI hangaia mō ngā hanganga toka waenga-mārō ki te mārō, e kapi ana i te mārō o te toka mai i te f=8 ki te f=18. He whānuitia te whakamahinga mō ngā kōhao pūmau whakapae, piko me te piki, me ngā kōhao pahū i roto i ngā kauhanga keri whenua. Mā te mahi i raro i te pēhanga hau paerewa o te 0.63MPa, ka puta te pūngao pānga pumau i runga ake i te 70J me te auau pānga neke atu i te 37Hz, e tuku ana i te kaha pakaru toka kaha me te haere tonu i te papaanga.
Me hono noa ngā ngongo hau paerewa 25mm te whānui o roto me ngā ngongo wai 13mm hei tīmata i te hanga. He kakau ergonomic me ngā takirere whakahaere tairongo te mea e hiahiatia ana e ngā kaimahi, ā, ka taea e te YT29A te whakarerekē ngāwari i te tere keri me te pana kia rite ki ngā āhuatanga toka tūturu. Ka whakaratohia e te miihini hinu raina FY250 kua hangaia he hinu whakahinuhinu aunoa tonu mō ngā wāhanga matua o roto puta noa i te huringa mahi, ka whakakore i ngā aukati tiaki ā-ringa maha. Nā tōna hanganga ngāwari ki te whakamahi, ka taea e ngā kaiwhakahaere hou te tere whakahaere i te tukanga keri katoa me te whakatutuki i te kounga keri pumau i muri i te whakangungu poto i te papaanga.
E kitea nuitia ana te pai ake o te mahi a te YT29A i ngā keri toka waewae-hau tuku iho i roto i ngā raraunga mahi maina tūturu. Ko te nuinga o ngā keri keri tuku iho ka eke ki te auau pānga 30Hz ki te 32Hz me te kaha pānga i raro i te 55J, ka hua ake he puhoi te tere pakaru o te toka me te iti o te pai o te hanga. I raro i te whakatakotoranga keri me ngā āhuatanga toka kotahi, ka roa ake te wā e pau ana i ngā taputapu tuku iho ki te whakaoti i ngā mahi keri pou.
I ngā wā o mua, i pau i ngā tīma keri keri e whakamahi ana i ngā keri toka paerewa te 18 ki te 24 hāora te toharite ki te whakaoti i te huringa whakarite katoa o ngā papa. Ka puta mai hoki i ngā taputapu tawhito te wiri kaha, te ngenge nui o te kaiwhakahaere me te maha o ngā pakaru o ngā wāhanga, ka puta ai te wā kore e taea te matapae. Whai muri i te whakapai ake ki teWiri toka YT29A, ka taea te whakaoti i te mahi keri pou taua i roto i ngā haora 10 ki te 12, ka whakaiti i te wā whakarite pou mā te tata ki te 50%.
Ko te hanganga pai o te whiu piston me te tohatoha hau o te YT29A ka tino whakaiti i te tuku wiri, ka whakaiti i te ngenge wiri o te kaiwhakahaere mā te 40%. Ka whakahaeretia te taumata haruru o te mīhini i raro i te 95dB, ka hangaia he taiao mahi haumaru ake, he whakamarie ake hoki i raro i te whenua. Mō te pumau me ngā huringa tiaki, me tirotirohia me te tiaki ngā keri tuku iho i ia 15 ki te 20 hāora mahi, ko te YT29A ia ka taea te whakahaere pumau mō te neke atu i te 60 hāora me te tiaki auau, ka tino whakaiti i te wā kore mahi me ngā utu tiaki mō ngā umanga keri.
I ahu mai te kounga hua pumau i te hanga wheketere paerewa. Ko te rahi o tā mātou turanga whakaputa he 24,000 mita pūrua, he nui atu i te 60 ngā taputapu tukatuka tika, ā, e tautokona ana e tētahi rōpū ngaio o te 105 ngā kaimahi tae atu ki te 16 ngā tohunga hangarau matua. Ko ia wāhanga matua o te YT29A ka tirotirohia rawatia, ka miihini tika, ka whakamahanahia hoki e te ngaio, kia pakari ai te mau o te taputapu ki te puehu, te makuku me te wiri nui i roto i ngā taiao o raro whenua.
Ka whakatinanahia e mātou te mana whakahaere kounga tino pakari, tae atu ki te whakamātautau tonu i ngā āhuatanga tino kino mō ngā haora 72 me te tirotiro 100% o ngā hua kua oti i mua i te tukunga. Ka hangaia motuhaketia, ka tukatukahia hoki ngā wāhanga matua katoa i roto i te whare, kia taea ai e mātou te whakahaere tino pakari i te kounga o te hua, te pumau o te tukunga me te ōritetanga i muri i te hoko. Ka taea e ngā kiritaki te tiki i ngā wāhanga e tika ana me te tautoko hangarau ngaio i te wā tika mō te mahi pumau mō te wā roa.
Haunga ngā whakapainga mahi, he nui ngā painga ōhanga ka kawea mai e te YT29A ki ngā kaupapa keri. Mā te tere o te whakarite i ngā tūāpapa ka whakapoto tika i te huringa kaupapa whānui, ka taea ai e ngā maina te uru ki te whakaputanga konganuku ōkawa 2 ki te 3 wiki i mua atu i ngā wātaka tuku iho. Ka whakaitihia e te pūnaha hau kua arotauhia te whakamahinga hau ki te ≤65L/s, he iti iho i te whakamahinga hau 85L/s ki te 95L/s o ngā keri toka noa, ka tapahia ngā utu pūngao whānui mā te 25%.
Mā te whakapakari hanganga kua whakapaitia me ngā taputapu matua kua whakapaitia, ka roa ake te ora o ngā wāhanga e te YT29A, ā, ka whakaitihia ngā utu whakakapinga wāhanga ā-tau mā te neke atu i te 40%. E whakaatu ana ngā manatoko maha o te mara maina he 15% ki te 20% teitei ake te whai huatanga whānui o ngā huringa whakarite tūnga mō ngā kaiwhakamahi YT29A. I taua wā anō, ka pehia e te pūnaha horoi wai whai hua te puehu o raro whenua, ka whakapai ake i te haumaru o te papaanga, ka whakaitihia hoki te kaha o te mahi a te kaiwhakahaere.
I tēnei wā, kua whānuitia te whakamahinga o te keri toka hau-waewae YT29A i roto i te keri whenua, te keri kauhanga me ngā kaupapa keri rua puta noa i te neke atu i te 20 whenua. Kei te arotau tonu mātou i ngā taipitopito hua e ai ki ngā urupare ā-ao, kia ngāwari ake ai te urutau o te YT29A ki ngā āhuatanga whenua uaua me ngā whakaritenga hanga kanorau. Hei otinga keri keri pakari me te utu-whai hua, kei te āwhina tonu te YT29A i ngā umanga keri o te ao ki te whakapai ake i te pai o te keri, te whakaiti i ngā utu whakahaere me te whakaū i te kounga hanga i runga i te papaanga.
