I roto i ngā kaiwhakamahi e whakamahi ana i ngā takirere porowhita whānui i ia rā, he maha ā rātou pūrongo mō te raruraru, arā, he uaua ki te kati i ngā takirere porowhita whānui ina whakamahia ki ngā pāpāho he nui te rerekētanga pēhanga, pērā i te mamaoa, te wai pēhanga teitei, me ētahi atu. Ina katihia me te kaha, ka kitea tonu he turuturu, ā, he uaua ki te kati pūmau. Ko te take o tēnei raruraru ko te hoahoa hanganga o te takirere me te kore e ranea o te taipana putanga o te taumata rohe tangata.

Te Tātari i te Uauatanga o te Whakawhiti i ngā Takirere Diameter Nui

Ko te kaha whakaputa pae whakapae toharite o te pakeke he 60-90kg, i runga i te āhua o te tinana.

Ko te tikanga, ko te ahunga rere o te takirere porowhita he mea hanga kia iti ki roto, kia teitei ki waho. Ina kati te takirere e te tangata, ka panaia e te tinana tangata te wira ringaringa kia huri whakapae, kia neke ai te taupoki takirere ki raro kia tutuki ai te kati. I tēnei wā, me wikitoria te huinga o ngā kaha e toru, arā:

(1) Te kaha pana tuaka Fa;

(2) Te kaha waku Fb i waenganui i te takai me te kakau takirere;

(3) Te kaha waku whakapā Fc i waenganui i te kakau takirere me te matua kōpae takirere

Ko te tapeke o ngā wā ko ∑M=(Fa+Fb+Fc)R

Ka kitea ko te nui ake o te diameter, ko te nui ake o te kaha pana tuaka. Ina tata ki te āhua kati, ka tata te kaha pana tuaka ki te pēhanga tuturu o te whatunga paipa (nā te P1-P2≈P1, P2=0)

Hei tauira, ka whakamahia he takirere porowhita DN200 ki runga i te paipa mamaoa 10-paera, ko te pana tuatahi anake o te kati ko te Fa=10×πr2=3140kg, ā, ko te kaha porowhita whakapae e hiahiatia ana mō te kati e tata ana ki te kaha porowhita whakapae ka taea e ngā tinana tangata noa te whakaputa. nō reira he tino uaua ki te tangata kotahi te kati katoa i te takirere i raro i tēnei āhuatanga.

Ae, e taunaki ana ētahi wheketere kia tāutahia aua takirere ki te taha whakamuri, ka ea ai te raruraru o te uaua ki te kati, engari kei reira anō te raruraru he uaua ki te whakatuwhera i muri i te katinga.

Te Tātari i ngā Take o te Tūtaki ā-roto o ngā Takirere Porowhita Diameter Nui

Ko ngā takirere porowhita whānui te whānui e whakamahia whānuitia ana i roto i ngā putanga o te poiha, i ngā rango matua, i ngā pūtake mamaoa me ētahi atu wāhi. Ko ēnei wāhi he raruraru e whai ake nei:
(1) I te nuinga o te wā, he nui te rerekētanga o te pēhanga i te putanga o te poiha, nō reira he nui ake te tere rere o te mamaoa, ā, he nui ake hoki te kino o te horo ki te mata hiri. Hei tāpiri, kāore e taea e te pai o te mura o te poiha te 100%, ka nui te wai o te mamaoa i te putanga o te poiha, ka ngāwari te pakaru me te pakaru o te mata hiri o te takirere.

(2) Mō te takirere aukati e tata ana ki te putanga o te pōro me te puoto-iti, nā te mea he āhua wera nui te mamaoa kua puta mai i te pōro, i roto i te tukanga o tōna whakakī, ki te kore e tino pai te maimoatanga whakangawari o te wai pōro, ka puta he wāhanga o te wai. Ka puta te waikura me te pirau i te mata hiri nā ngā matū waikawa me te kawakore; ka piri pea ētahi matū tioata ki te mata hiri o te takirere ka tioata, ka kore e taea e te takirere te hiri pūmau.

(3) Mō ngā takirere tomo me te putanga o ngā puoto iti, he nui te mamaoa e pau ana i muri i te takirere, ā, he iti i ētahi wā nā runga i ngā whakaritenga whakaputa me ētahi atu take. Ka pā te mimiti, te pakaru me ētahi atu kino ki te mata hiri o te takirere.

(4) I te nuinga o te wā, ina whakatuwheratia he paipa whānui, me whakamahana te paipa, ā, ko te tikanga, me rere te mamaoa i roto i te tukanga whakamahana, kia taea ai te whakamahana āta me te ōrite o te paipa ki tētahi taumata i mua i te whakatuwheratanga katoa o te takirere aukati kia kore ai e pakaru te paipa. Ka nui te whānui o te wera i te wera tere, ka pakaru ētahi wāhanga hononga. Heoi, i roto i tēnei tukanga, he iti rawa te whakatuwheratanga o te takirere, ka nui ake te tere o te pirau i te whakamahinga noa, ā, ka tino whakaiti i te roa o te mahi o te mata hiri takirere.

Ngā otinga mō ngā uauatanga ki te whakawhiti i ngā takirere porowhita whānui

(1) Tuatahi, he mea pai kia whiriwhiria he takirere porowhita kua hiritia ki te pupuhi, hei karo i te awe o te ātete waku o te takirere plunger me te takirere tākai, ā, hei whakangāwari ake i te pana.

(2) Me hanga te matua o te takirere me te nohoanga takirere ki ngā rauemi e ātete ana ki te horo me te kaha ki te mau, pērā i te Stellite carbide;

(3) E taunakihia ana kia whakamahia he hanganga kōpae takirere takirua, e kore ai e nui te pakaru nā te iti o te whakatuwheratanga, ka pā ki te roa o te ratonga me te pānga hiri.
