Ko te pupuhi i te rua kohatu nui me whai wāhi ōrite, me te keri tonu i ngā kōhao.Wiri toka S250Mā te keri ōrite ka tutuki tēnei mā te weronga pumau me te whakahaere whakahaere. Ka pai ake ngā hua pahūtanga i te keri ōrite, ka whakaiti i te rahi o te toka, ā, ka whakaiti i ngā utu pakaru tuarua.
Hei kaihanga ngaio e tohunga ana kikeri tokamīhini, ka rangahau motuhake a Shenli Pneumatic Machinery Co., Ltd., ka whakawhanake, ka whakaputa hoki i te wiri toka mata S250, he taputapu keri hau mahi teitei kua hangaia mō te pupuhi i te rua kohatu nui. Ko teS250He māmā te whakahaere: honoa ki tētahi pūwero hau e ōrite ana hei whakarato i te mana pumau, whakarerekētia te hohonutanga me te tere o te keri kia rite ki te pakeke o te toka, ā, mā tōna hoahoa ergonomic ka taea e te kaiwhakahaere kotahi te whakaoti i te mahi keri kia maeneene me te kore he whakangungu uaua. He rerekē ki ngā keri toka waewae-hau tuku iho, ka whakauruhia te pumau me te whai huatanga, ka kore e hiahiatia he whakarerekētanga ā-ringa auau i te wā e whakahaerehia ana.

Te rerekētanga i waenga i te whakamahi i te S250 me te mea noawiri toka waewae hauHe mea whakamiharo te mahi i roto i ngā maina. I mua i te whakamahinga o te S250, he iti te pai o te keri o ngā keri toka waewae-hau noa, 2-3 mita noa iho ia hāora, me te koretake o te tawhiti o ngā kōhao me te ngāwari o te peka, ka hua ake he pupuhi koretake, he nui ake ngā kōhao, me te nui o ngā utu pakaru tuarua. I muri i te huri ki te S250, ka piki ake te pai o te keri mā te 65%, ka tae ki te 5-6 mita ia hāora. Mā tana mahi tika ka whakarite kia ōrite te tawhiti o ngā kōhao me te hohonu, e kore e arotau noa i te pānga pupuhi me te whakaiti i ngā kōhao nui mā te 40%, engari ka tapahia hoki ngā utu pakaru tuarua mā te 35%. Hei tāpiri, he haruru, he nui hoki te mahi a ngā keri toka waewae-hau noa, ko te S250 ia e whakamahi ana i te hangarau whakaiti haruru matatau, e whakaiti ana i te haruru mā te 50% me te whakaiti nui i te ngenge o te kaiwhakahaere.

Ko te whiriwhiri i te Shenli Pneumatic Machinery Co., Ltd. ko te tikanga he whiriwhiri i te pono me te whai hua. E 15 tau ō mātou wheako ki te hanga mīhini keri toka, me te raina whakaputa katoa me te pūnaha whakahaere kounga tino pakari, me te whakarite kia tutuki i ia S250 ngā paerewa ahumahi. Ka whakaratohia e mātou ngā otinga ritenga kia rite ki ngā hiahia o ngā rua kohatu rerekē, me te ratonga muri-hoko 24-hāora hei whakaoti rapanga mahi i te wā tika. Ehara i te mea ka whakapai ake te S250 i te whai huatanga o te keri me te whakaiti i ngā utu, engari he pakari hoki, me te roa o te ora ratonga e 2 ngā wā i ngā keri toka noa, ka whakaiti i ngā utu whakakapinga taputapu. Mō ngā rua kohatu e whai ana i te whai huatanga teitei me te utu iti, ko te S250 te kōwhiringa tino whai hua.
