Me pēhea te whakamahi pai ake i te whitiki maitai?
He nui te āwangawanga o ngā kaiwhakamahi whitiki maitai mō te roa o te ora o ngā whitiki maitai, kua whakarāpopototia e mātou ngā kōrero e whai ake nei e pā ana ki te roa o te ora o ngā whitiki maitai, me te tumanako kaāwhinakia mārama ake koe ki ā mātou whitiki maitai.
Fi te tuatahi, ka nui rawa te taumahatanga ka pā ki te whitiki maitaikaka pā ki te roanga o te ratonga.
He aha te ahotea pai rawa atu mō te whitiki maitai? Ko te tikanga, ko te iti o te ahotea e pā ana ki te whitiki maitai, ko te roa ake o te ora, me hono atu ki ngā hiahia o ngā kaiwhakamahi ki te whakaputa hua rapa. I te nuinga o te wā, ko te tango i te tono whitiki maitai MT1650 i roto i te DLG-7Hei tauira, ko ngā taputapu 00X1400 o te wheketere mīhini rapa o Shanghai Nama 1, ko te nuinga o ngā kaiwhakamahi whakaputa ka whakarerekē i te uara o te ine waipēhi ki te 15~20Mpa. Hei tāpiri, nā te rerekētanga o ngā diameter o ngā rango waipēhi e whakamahia ana e te kaiwhakamomona pahu hei tautoko i ngā roera toronga, ka rerekē anō hoki ngā uara motuhake. Tena koa whakapā atu ki te kaihanga taputapu mō ngā uara motuhake e tohua ana e te ripanga waipēhi o te kaiwhakamomona pahu.
Tuarua, he maha ngā kaiwhakamahi e whakaaro ana ko te matotoru o te whitiki maitai, ko te roa aketōna roanga orai mua i te hoko, he hē kē tēnei. Ahakoa ka taea e te whitiki maitai matotoru te tu atu i te pānga o ngā mea pakeke i roto i te rauemi, ā, ehara i te mea ngāwari ki te whakaputa i ngā poka nui, he nui te porowhita piko o te whitiki maitai matotoru, he tairongo ake ki te kino o te ngenge i puta mai i te piko tonu, ā, he nui ake te ahotea piko, nō reira he matotoru ake te whitiki maitaikāore pea e roa ake te ora ratonga.
Hei tāpiritanga, i muri i te tāutanga o te whitiki maitai, kāore e tika ana kia whakarerekē tonu i te pēhanga ki te uara e hiahiatia ana mō te whakaputanga, ā, me whakapiki haere te pēhanga kia tae rā anō ki te mahi noa. Me whakapiki haere hoki te pāmahana o te whitiki maitai hei whakaiti i te rerekētanga o te ahotea o roto i puta mai i te whānui me te whakahekenga wera, ā, kaua e tīmata te taputapu whakamahana ina mutu te mahi a te kaiwhakawera wera.
Hei whakamutunga, mēnā ko ngā āhuatanga e whai ake neikāore e arohia anai te wā e whakamahia ana, ka ngāwari hoki te whitiki maitai ki te pakaru:
1) He kino nui ki te whitiki maitai nā te mahi hē. Mena ka taupokina te rauemi rapa, ka uru ngā mea ke atu i te mea rite ki ngā taputapu tiaki ki te whakamomona i te pahu, ka puta he rerekētanga ā-rohe o te rīpene maitai, ka waiho he tohu ki te mata o te hua.
2) He roa rawa te wā tiaki, ā, me horoi te mata o te whitiki maitai i ia wiki.
3) Te kounga iti o ngā rauemi mata kua whakamomonatia. Ko te take nui o tēnei ko te nui rawa o te ahotea ā-rohe i puta mai i ngā mea ke pakeke i roto i ngā rauemi mata.
4) Kāore te taputapu e mahi tika ana. Hei tauira, ko te he o te whitiki maitai nā ngā take maha ka arahi ki te wiri o te whitiki maitai.
5) Ka hangaia hekoikoki, e hua ai te kukū o te ahotea me ngā kapiti
6) Kāore i tino horoia te whitiki maitai,mengā mea ke e piri ana ki te mata o roto o te whitiki maitai
7) He whaiti ake te hua rapa i te whānui o te whitiki maitai, ā, ka roa te wā e kaha ana te taha o te hua rapa whakamomona ki te tūranga kotahi o te whitiki maitai.
8) He nui rawa te kaha o te rōra whakatikatika ā-ringa, he maha rānei ngā whakatikatika o te pūwero whakamomona
Ētahi tātaitanga e tika ana mō ngā kaiwhakakorikori i te pahu
1. Te whānui me te roa o te pahu
Mā te pūwero pahu e whakaoti te whakamahana, te pēhanga me te whakawero i te hua i runga i te pahu whakawero. Nō reira, ko te whānui me te roa o te pahu whakawero tētahi o ngā tawhā tino whakaatu.
