hiri papuKo te pakaru me te turuturu tetahi o ngā tino take e roa ai te wā e kore ai e mahi te papu, ā, he maha ngā āhuatanga ka puta mai. Hei karo i te pakaru me te turuturu o te hiri papu, he mea nui kia mārama ki te raruraru, kia tautuhia te hapa, kia kore ai hoki ngā hiri o muri mai e pā kino atu ki te papu me ngā utu tiaki. I konei, ka tirohia ngā tino take e pakaru ai ngā hiri papu me ngā mea ka taea e koe te mahi hei karo i aua mea.
Ngā hiri mīhini papukoinei te wāhanga tino nui o ngā papu. Mā ngā hiri ka ārai i te turuturu o te wai i papua, ā, ka ārai hoki i ngā poke pea.
E whakamahia ana ēnei hei neke i ngā momo wai i roto i ngā ahumahi pēnei i te hinu me te hau, te whakaputa hiko, te wai me te wai para, te kai me te inu, me ētahi atu. Nā te whānui o te whakamahinga, he mea nui kia tautuhia te turuturu, kia āraihia ai te haere tonu.
Me whakaae ka turuturu ngā hiri papu katoa; me pēnā tonu, kia mau tonu ai te kiriata wai ki runga i te mata o te hiri. Ko te kaupapa o te hiri he whakahaere i te turuturu. Heoi, ko ngā turuturu kāore i te whakahaeretia, me te nui rawa hoki, ka pā kino ki te papu mena kāore e tere te whakatika.
Ahakoa he hapa tāutanga, he hapa hoahoa, he kakahu, he poke, he hapa wāhanga, he hapa kāore e pā ana ki te kēne te take i pakaru ai te hiri, he mea nui kia tātaritangahia te take i te wā tika, kia mōhio ai mēnā me whakatika hou, me tāuta hou rānei.
Mā te mārama ki ngā take o te pakaru o te hiri papu, me ētahi tohutohu, aratohu me te whakamahere ngāwari, ka māmā ake te karo i ngā turuturu a meake nei. Anei te rārangi o ngā take tino noa mō te pakaru o te hiri papu:
Hapa tāutanga
I te wā e tātaritanga ana i te rahunga o te hiri papu, me tirotiro tuatahi te tukanga tīmatanga me te tāutanga o te hiri. Koinei te tino take o te rahunga o te hiri. Ki te kore e whakamahia ngā taputapu tika, kei te pakaru kē te hiri, kāore rānei te hiri i tāutahia ki te huarahi tika, ka tere te pakaru o te papu.
Mā te tāuta hē i te hiri papu ka maha ngā hapa ka pā mai, pērā i te kino o te elastomer. Nā te mata tairongo, papatahi o te hiri papu, ahakoa he iti noa te paru, te hinu, ngā tohu tapumati rānei, ka taea te arahi ki te kore e tika te tūnga o ngā mata. Ki te kore e tika te tūnga o ngā mata, ka uru te turuturu nui ki roto i te hiri papu. Ki te kore hoki e tirohia ngā wāhanga nui ake o te hiri – pērā i ngā pūtu, te whakahinuhinu, me te whirihoranga pūnaha tautoko – kāore pea te hiri e mahi tika mai i te tāutanga.
Ko ngā take tino noa mō te tāutanga hē o te hiri ko:
• Te wareware ki te whakau i ngā tīwiri kua whakatakotoria
• Te kino i ngā mata o te hiri
• Te whakamahi hē i ngā hononga paipa
• Kāore i te whakakīkī ōrite i ngā pūtu repe
Ki te kore e kitea i mua i te tīmatanga o te papu, ka hua pea he hapa tāutanga ka pakaru te motuka me te takahuri o te toki, ka puta ai te nekehanga porowhita me te pa o ngā wāhanga o roto. Ka hua ake tēnei i te pakaru o te hiri me te roa o te ora o te peera.
Te whiriwhiri i te hiri hē
Ko te kore mōhiotanga i te wā e hoahoa ana, e tāuta ana hoki i te hiri tētahi atu take noa mō te pakaru o te hiri, nō reira he mea nui te whiriwhiri i te hiri tika. He maha ngā āhuatanga hei whakaaroaro māu i te wā e whiriwhiri ana i te hiri tika mō te papu, pēnei i:
• Ngā āhuatanga whakahaere
• Ngā mahi kore-tukatuka
• Te horoi
• Te korohū
• Waikawa
• Ngā waikura werawera
• Te āheinga mō ngā haerenga rerekē
Me hototahi te rauemi o te hiri ki te wai i roto i te papu, ki te kore ka pakaru te hiri, ā, ka nui ake te kino i tua atu i te turuturu o te wai. Hei tauira, ko te whiriwhiri i tētahi hiri mō te wai wera; kāore e taea e te wai i runga ake i te 87°C te whakahinuhinu me te whakamatao i ngā mata hiri, nō reira he mea nui kia whiriwhiria he hiri me ngā rauemi elastomer me ngā tawhā whakahaere tika. Mena ka whakamahia te hiri hē, ā, ka ngoikore te hiri papu, ka tino pakaru te hiri i te waku nui i waenga i ngā mata hiri e rua.
He maha ngā wā ka warewarehia te kore hototahi matū o te hiri i te wā e whiriwhiri ana i ngā hiri papu. Mēnā he kore hototahi te wai ki te hiri, ka pakaru, ka pupuhi, ka kōpiri, ka pirau rānei ngā hiri rapa, ngā gasket, ngā impeller, ngā anga papu me ngā diffuser. He maha ngā wā me whakawhiti ngā hiri i te wā e whakawhiti ana i te wai waipēhi i roto i te papu. I runga i te wai o te papu, me hiahia pea he hiri i hangaia ki te rauemi hou, motuhake hei karo i te pakaru. He whakaritenga anō tō ia wai me ia hoahoa papu. Mā te whiriwhiri i te hiri hē ka whakarite i ngā wero me ngā kino motuhake mō te tono.
Rere maroke
Ka puta te rere maroke ina mahi te papu me te kore he wai. Mena ka nui ake te waku o ngā wāhanga o roto o te papu, e whakawhirinaki ana ki te wai i papuhia mō te whakamatao me te whakahinuhinu, me te kore e ranea te whakahinuhinu, ka arahi te wera hua ki te pakaru o te hiri. Ko te nuinga o ngā pakaru o te rere maroke ka puta mā te tīmata anō i te papu i muri i te tiaki me te kore e tirotiro kua kī katoa te papu i te wai.
Ki te maroke te papu, ā, ka piki ake te wera ki tua atu i te kaha o te hiri, tera pea ka pāngia te hiri papu e te kino kino. Tērā pea ka wera, ka rewa rānei te hiri, ka turuturu te wai. Mēnā he torutoru hēkona noa iho o te rere maroke, ka pakaru te hiri i te wera, ka pupuhi rānei, ka turuturu te hiri o te pou o te papu.
I ngā wā tino kino, ina pāngia te hiri e te ru wera, ka pakaru pea i roto i te 30 hēkona, iti iho rānei. Hei ārai i tēnei momo kino, tirohia te hiri papu; ki te mea kua maroke te hiri, ka mā te mata o te hiri.
Ngā wiri
Ka neke, ka wiri hoki ngā papu. Heoi, ki te kore te papu e taurite tika, ka piki ake ngā wiri o te mīhini tae noa ki te wāhi e pakaru ai. Ka taea hoki te wiri o te papu i te kore tika o te whakarite me te whakahaere i te papu kia tawhiti rawa ki te taha maui, ki te taha matau rānei o te Pūwāhi Pai Rawa (BEP) o te papu. Mā te nui rawa o te wiri ka nui te takaro axial me te radial o te rakau, ka hē te whakarite, ā, ka nui ake te wai e turuturu ana i roto i te hiri.
Ka taea hoki te puta o ngā wiri i te nui rawa o te hinu whakahinuhinu; ka whakawhirinaki te hiri miihini ki tētahi kiriata angiangi o te hinu whakahinuhinu i waenganui i ngā mata hiri, ā, ka ārai te wiri nui rawa i te hanganga o tēnei paparanga hinu whakahinuhinu. Mena me mahi te papu i roto i ngā āhuatanga taumaha, pērā i ngā papu keri, me kaha te hiri e whakamahia ana ki te whakahaere i te purei axial me te radial i runga ake i te toharite. He mea nui hoki kia tautuhia te BEP o te papu, me te whakarite kia kaua te papu e nui ake, e iti iho rānei i tōna BEP. Ka pā mai pea tēnei i ngā momo kino maha atu i te turuturu o te hiri.
Te kakahu o te peera
I te hurihuri o te rakau o te papu, ka pakaru ngā peera nā te waku. Ka piupiu te rakau i ngā peera kua pakaru, ā, ka puta he wiri kino, kua kōrerohia e tātou ngā hua o taua mea.
Tērā pea ka puta noa te pakaru i te roanga o te oranga o te hiri. Ka pakaru noa ngā hiri i te roanga o te wā, ahakoa he maha ngā wā ka tere ake te pakaru o te poke, ka whakaiti hoki i te roa o te ora. Tērā pea ka puta tēnei paru i roto i te pūnaha tautoko hiri, i roto rānei i te papu. He pai ake ētahi wai ki te pupuri i ngā poke mai i te hiri papu. Mena kāore he take kē atu mō te pakaru o te hiri, whakaarohia te whakawhiti wai hei whakapai ake i te roanga o te oranga o te hiri. Waihoki, ko ngā peera kounga teitei ake he iti ake te tūponotanga ka hē te āhua i te pēhanga kawenga, nō reira he mea nui kia whakaitihia te momo pa o te konganuku ki te konganuku ka puta ai te paru.
