Te Pere Waro Iti
Whakataki hua：
He rite tonu te tukanga whakaputa ki te paerewa ā-motu o te pere maitai, mā te whakamahi i te hangarau granulation centrifugal, nā te mea he rino waro iti te rauemi mata, nō reira kaua e whakamahia te tukanga whakamahana pāmahana teitei, engari mā te whakamahi i te tukanga whakamahana isothermal.
Āhuatanga
KARAPONA RINO ITI
UTU PAINGA
• Neke atu i te 20% te mahi ki ngā werohanga waro-nui
• He iti ake te pakaru o ngā mīhini me ngā taputapu nā te nui ake o te mimiti o te pūngao i roto i ngā pānga o ngā wahi
• Ngā matūriki kāore he hapa i puta mai i te maimoatanga wera, ngā whatiwhatinga, ngā kapiti moroiti rānei
TE WHAKAPAPA I TE TAIAO
• Mō tōna whakaputanga, kāore e hiahiatia he maimoatanga wera i muri mai
• Te whakaiti i te paura
• Ka whakamanahia e te hanganga moroiti bainitic kāore e pakaru i te roanga o tōna oranga whai hua
ĀHUA WHĀNUI
• He rite te āhua o te pere maitai waro-iti ki te porowhita. Kāore e nui ngā matūriki roa, āhua rerekē me ngā pūwero, te para, te paru rānei.
• Kāore tēnei e pā ki te mahi a te pupuhi, ka taea te whakaū mā te ine i tōna mahi i runga i te mīhini.
PAKARIKI
• Mā te hanganga moroiti bainitic ka tino pakari. 90% o ngā matūriki kei waenga i te 40 - 50 Rockwell C.
• Mā te iti o te waro me te konupora e taurite ai te roa o te ora o ngā matūriki, ā, ka pai ake te ma o ngā wahi, nā te mea ka piki ake te pakeke o ngā wahi i roto i te mahi miihini.
• Ko te kaha o te pupuhi pupuhi ka mimitihia e ngā wāhanga, ā, ka whakaitihia te pakaru o te mīhini.
TE WHAKAKĀHĀ WARO, TE WHAKAMAHI TINO HIRANGA
• Ka taea te whakamahi i te pere maitai waro iti mō ngā mīhini he 2500 ki te 3000 RPM ā rātou tāpine me te tere o te 80 M/S.
• Mō ngā taputapu hou e whakamahi ana i ngā tāpine 3600 RPM me ngā tere o te 110 M/S, koinei ngā whakaritenga hei whakapiki i te hua.

| I te wā e pupuhi ana te maitai waro iti i roto i te porowhita, kāore te pere maitai waro iti e pakaru ki ngā matūriki iti, ā, ka mau tonu tōna āhua porowhita. | I te wā e pupuhi ana, ā, nā te pakaru o te mata, ka pakaru te pupuhi ki ngā wahi nunui me ngā pito koi i roto i te wā poto. Nā tēnei, ka nui ake ngā utu tiaki ka puta mai i ngā pupuhi waro nui, mā te whakanui ake i te pakaru o ngā mīhini pupuhi. |
