He maha ngā momo taputapu e hiahia ana kia hiritia te pou hurihuri e haere ana i roto i te whare tūmau. Ko ngā tauira e rua e kitea whānuitia ana ko ngā papu me ngā mīhini whakaranu (ngā mīhini whakaoho rānei). Ahakoa ko te mea taketake
He rite tonu ngā mātāpono o te hiri i ngā taputapu rerekē, engari he rerekētanga e hiahia ana ki ngā otinga rerekē. Nā tēnei hē o te māramatanga kua ara ake ngā pakanga pērā i te karanga i te American Petroleum Institute
(API) 682 (he paerewa hiri miihini papu) ina tohua ana ngā hiri mo ngā mīhini whakaranu. Ina whakaarohia ana ngā hiri miihini mo ngā papu me ngā mīhini whakaranu, he iti noa ngā rerekētanga kitea i waenga i ngā kāwai e rua. Hei tauira, he poto ake ngā tawhiti o ngā papu whakairi (i te nuinga o te wā ka inehia i roto i te inihi) mai i te impeller ki te peera radial ina whakaritea ki te mīhini whakauru o runga noa (i te nuinga o te wā ka inehia i roto i te putu).
Nā tēnei tawhiti roa kāore i te tautokona, ka iti ake te pumau o te tūāpapa me te nui ake o te rere radial, te koretake o te tūnga poutū me te rerekētanga i ngā papu. Ko te nui ake o te rere taputapu he wero hoahoa mō ngā hiri miihini. Me pēhea mēnā he radial anake te piko o te toki? Ka taea te hanga hiri mō tēnei āhuatanga mā te whakanui ake i ngā āputa i waenga i ngā wāhanga hurihuri me ngā wāhanga tūmau me te whānui ake o ngā mata o te mata hiri. E ai ki te whakapae, ehara i te mea ngāwari ngā take. Ko te uta taha ki runga i te(ngā) impeller, ahakoa kei hea rātou i runga i te toki whakaranu, ka tukuna he piko e whakawhiti ana i roto i te hiri ki te pūwāhi tuatahi o te tautoko toki—te whīra radial o te pouaka miihini. Nā te piko o te toki me te nekehanga pendulum, ehara te piko i te mahi raina.
Ka whai wāhanga porowhita me te koki tēnei e hanga ana i te he o te hiri poutū ka raru pea te hiri miihini. Ka taea te tatau i te piko mena e mōhiotia ana ngā āhuatanga matua o te rakau me te uta o te rakau. Hei tauira, e kī ana te API 682 me rite te piko porowhita o te rakau i ngā mata hiri o te papu ki te 0.002 inihi te katoa o te pānui tohu (TIR) i ngā āhuatanga tino kino. Ko ngā awhe noa i runga i te mīhini whakaranu whakauru o runga kei waenga i te 0.03 ki te 0.150 inihi TIR. Ko ngā raruraru i roto i te hiri miihini ka puta mai i te piko nui o te rakau ko te nui haere o te kakahu ki ngā wāhanga hiri, te hurihuri o ngā wāhanga e pā ana ki ngā wāhanga tūmau e kino ana, te hurihuri me te kōpeke o te mowhiti-O hihiri (ka pakaru te mowhiti-O i te porowhita, te iri rānei o te mata). Ka taea e ēnei katoa te arahi ki te whakaiti i te roa o te hiri. Nā te nui o te nekehanga i roto i ngā mīhini whakaranu, ka nui ake te turuturu o ngā hiri miihini ki te whakataurite ki ngā mea rite.ngā hiri papu, ka taea e tēnei te arahi ki te toia koretake o te hiri, me/ranei te pakaru wawe ki te kore e aro turukihia.
Tērā ētahi wā, ina mahi tahi ana me ngā kaihanga taputapu, me te mārama ki te hoahoa o ngā taputapu, ka taea te whakauru i tētahi peera huānga hurihuri ki roto i ngā kātere hiri hei whakawhāiti i te koki i ngā mata hiri, hei whakaiti hoki i ēnei raruraru. Me āta whakamahi i te momo peera tika, me te mārama katoa ki ngā kawenga peera pea, ki te kore ka kino haere te raruraru, ka puta rānei he raruraru hou, mā te tāpiri i tētahi peera. Me mahi tahi ngā kaihoko hiri me te OEM me ngā kaihanga peera kia tika ai te hoahoa.
He iti te tere o ngā whakamahinga hiri whakaranu (5 ki te 300 hurihanga ia meneti [rpm]) ā, kāore e taea te whakamahi i ētahi tikanga tuku iho hei pupuri i te matao o ngā wai ārai. Hei tauira, i roto i te Mahere 53A mō ngā hiri takirua, ka whakaratohia te rere o te wai ārai e tētahi āhuatanga papu ā-roto pērā i te tīwiri papu tuaka. Ko te wero ko te āhuatanga papu e whakawhirinaki ana ki te tere o ngā taputapu hei whakaputa rere, ā, kāore i te nui ngā tere whakaranu noa hei whakaputa tere rere whai hua. Ko te rongo pai ko te wera i puta mai i te mata o te hiri ehara i te mea e piki ake ai te pāmahana o te wai ārai i roto i tehiri whakaranu. Ko te mimiti wera mai i te tukanga ka piki ake te pāmahana o te wai ārai, ā, ka ngoikore hoki ngā wāhanga hiri o raro, ngā mata me ngā elastomer, hei tauira, ki ngā pāmahana teitei. Ko ngā wāhanga hiri o raro, pērā i ngā mata hiri me ngā mowhiti-O, ka ngoikore ake nā te mea e tata ana ki te tukanga. Ehara i te wera te mea e kino tika ana ki ngā mata hiri, engari ko te iti o te matotoru, nō reira, te hinu o te wai ārai i ngā mata hiri o raro. Ko te hinu ngoikore ka kino te mata nā te pa atu. Ka taea te whakauru i ētahi atu āhuatanga hoahoa ki roto i te kātere hiri hei pupuri i te pāmahana ārai kia iti, hei tiaki hoki i ngā wāhanga hiri.
Ka taea te hoahoa i ngā hiri mīhini mō ngā mīhini whakaranu me ngā koiri whakamatao ā-roto, ngā koti rānei e pā tika ana ki te wai ārai. Ko ēnei āhuatanga he pūnaha porowhita kati, pēhanga iti, rere iti, e rere ana te wai whakamatao mā roto i a rātou hei whakawhiti wera whakauru. Ko tētahi atu tikanga ko te whakamahi i te pōkai whakamatao i roto i te kātere hiri i waenganui i ngā wāhanga hiri o raro me te mata whakairi taputapu. Ko te pōkai whakamatao he kōhao ka taea e te wai whakamatao pēhanga iti te rere mā roto hei hanga i tētahi ārai ārai i waenganui i te hiri me te oko hei whakaiti i te mimiti wera. Ka taea e te pōkai whakamatao kua hoahoatia tika te ārai i ngā pāmahana nui rawa ka hua ake he kino ongā mata hirime ngā elastomers. Engari, ka piki ake te pāmahana o te wai ārai nā te mimiti wera mai i te tukanga.
Ka taea te whakamahi ngātahi i ēnei āhuatanga hoahoa e rua, ka taea rānei te whakamahi takitahi hei āwhina i te whakahaere i ngā pāmahana i te hiri mīhini. He maha ngā wā, ka tohua ngā hiri mīhini mō ngā mīhini whakaranu kia tutuki i te API 682, Putanga Tuawhā Kāwai 1, ahakoa kāore ēnei mīhini e tutuki i ngā whakaritenga hoahoa i roto i te API 610/682 i runga i te mahi, te rahi me/te mīhini rānei. Tērā pea nā te mea kua mōhio ngā kaiwhakamahi mutunga ki te API 682 hei whakatakotoranga hiri, ā, kāore i te mōhio ki ētahi o ngā whakatakotoranga ahumahi e tika ana mō ēnei mīhini/hiri. Ko ngā Mahi Ahumahi Tukanga (PIP) me te Deutsches Institut fur Normung (DIN) ngā paerewa ahumahi e rua e tika ana mō ēnei momo hiri—kua roa te wā e tohua ana ngā paerewa DIN 28138/28154 mō ngā OEM mīhini whakaranu i Ūropi, ā, kua whakamahia te PIP RESM003 hei whakaritenga whakatakotoranga mō ngā hiri mīhini i runga i ngā taputapu whakaranu. I tua atu i ēnei whakaritenga, kāore he paerewa ahumahi e whakamahia whānuitia ana, e hua ake ai he whānuitanga o ngā rahi o te rūma hiri, ngā ātete miihini, te piko o te rakau, ngā hoahoa pouaka miihini, ngā whakaritenga peera, me ētahi atu, e rerekē ana i ia OEM ki ia OEM.
Ko te wāhi noho me te ahumahi o te kaiwhakamahi te mea nui hei whakatau ko tēhea o ēnei whakaritenga e tino tika ana mō tā rātou pae.hiri miihini whakaranuKo te tohu i te API 682 mō te hiri whakaranu he utu tāpiri koretake, he uauatanga hoki. Ahakoa e taea ana te whakauru i tētahi hiri taketake whai tohu API 682 ki roto i tētahi whirihoranga whakaranu, he maha ngā wā ka puta he raruraru i tēnei huarahi i runga i te tutuki i ngā whakaritenga ki te API 682 me te pai o te hoahoa mō ngā tono whakaranu. E whakaatu ana te Whakaahua 3 i tētahi rārangi rerekētanga i waenga i tētahi hiri Kāwai 1 API 682 me tētahi hiri mīhini whakaranu noa.
