He iti te ātete o ngā takirere e whakaaturia ana i te pikitiangā takirere tirotiro whakatītaha me te hama taumahai hangaia e Jinbin Valve, me ngā rahi mai i te DN250 ki te DN700. He mea hanga te tinana takirere ki te maitai waro WCB, he mea whakarite ki ngā taumaha taurite me ngā rango waipēhi, ā, he mea whakatau mō ngā pēhanga mahi PN16, PN20 me te PN25.

Ko tēnei takirere ārai pūrerehua ātete-iti me te ātete-pūrerehua he hanganga whakatuwhera-kati e rua ngā wāhanga. Ina rere te papu wai, ka panaia te kōpae pūrerehua e te pēhanga reo kia tuwhera; ka hiki te taumaha ātete me te kōpae hei taurite i te taumaha-ake o te pereti pūrerehua, ka whakaiti nui i te ātete rere o te wai. I taua wā, ka rere te reo ki roto i te rango waipēhi hei pupuri i te pēhanga. I te wā e kati ana te papu, i raro i te kaha whakakotahi o te taumaha-ake, te taumaha ātete me te pēhanga rere whakamuri, ka tere te kati o te kōpae pūrerehua i te 80%~90% o te rerenga rere hei aukati i te nuinga o te rere whakamuri. Ko te toenga o te 10%~20% o te whiu ka kati mā te whakamātao i te rango waipēhi. Mā te takirere ngira ka taea te whakarite tika i te roa o te kati-pōturi, ka whakamarara i te kaha pānga o te rere whakamuri i ia taahiraa, ā, ka pehi i ngā ngaru wiri hama wai.

Ngā Painga Matua o te Taupānga

1. Whakakorehia te hama wai, ā, tiakina ngā taputapu

Ka ngoikore te hama wai pēhanga teitei e puta ana i te wā e kati ana te papu mā te katinga ā-wāhanga, ka ārai i te pakaru o te paipa me te kino o te hurihanga o te pou o te papu, ā, ka tino whakaiti i ngā utu tiaki paipa.

2. Ātete rere tino iti mō te penapena pūngao

Ka whakataurite te taumaha taurite i te taumaha o te pereti pūrerehua kia kore ai e araia te rere o te wai e tuwhera katoa ana. Neke atu i te 40% te iti iho o tōna ngaronga upoko i tērā o ngā takirere tirotiro hurihuri tuku iho, e tuku ana i te mana mō te wā roa me te penapena utu.

3. He mahi hiri pumau me te pono

He hanganga hiri kōpae pūrerehua takirua-āhua rerekē tōna mō te kati pūmau. Kua pania te tinana takirere ki te peita ārai-waikura epoxy, he mea e tika ana mō ngā momo pāpāho tae atu ki te wai ma, te wai para me te wai e rere ana.

4. Te whakarerekētanga ngāwari me te whānui o te whakamahinga

Mā te pūnaha whakamātao waipēhi motuhake ka taea te whakatikatika i te wā kati puhoi i runga i te tono. He pai ake te mahi i ngā takirere tirotiro puku puna-utaina mā te tawhiti nui mō ngā teihana papu whānui nui (DN300 me runga ake).

Ka kati tonu ngā takirere tirotiro paerewa noa, ka tere te puta o te hama wai nui. Ka whakapotohia te roa o te mahi a ngā papu wai, ngā paipa me ngā flange e te pānga pinepine. Ko ngā momo pūwero-pū e tika ana mō ngā rahi iti anake, kāore i te rawaka te kaha pana me te tautoko mō ngā diameter nui.

He mea hanga motuhake tēnei takirere mō ngā putanga papu, e toru ngā mahi e whakauru ana: te kore-hoki, te pehi hama wai me te ātete rere iti. Ka whakakapia e ia te huinga o te takirere tirotiro paerewa me te taputapu ārai, hei whakaiti i ngā hononga paipa. I roto i ngā pūnaha rere nui pēnei i te tuku wai ā-tāone, te wai e rere ana i te tipu hiko, te tuku wai matū me te rerenga wai, me ngā teihana papu paru, ka tiakina te haumaru o te mahi paipa, ka roa ake te roa o te ratonga o te huinga taputapu katoa, ā, ka tukuna he mahi utu pai ake i roto i te whakahaere me te tiaki whānui.
