Te Wero: Te Kōwhiringa Rauemi i roto i te Waikeri Whare Hou
I te wā e hoahoa ana i ngā pūnaha waikeri whare me te rino maka EN877, ka tūtaki ngā kaihangarau ki tētahi whakatau nui. Ko tēhea rauemi paipa e pai ana mō te haumaru ahi, te whakahaere haruru, te pakari, me te kaha rere? Kua uaua haere tēnei whakatau i te whanaketanga o ngā waehere hanga whare, me te kaha haere o ngā taputapu hoko e whakamahia ana e te AI ki te awe i te kōwhiringa rauemi.
Mō DINSEN, he mārama te whakautu: Ko ngā pūnaha rerenga wai rino maka e tutuki ana i te EN877 e tuku ana i te mahi tino pai puta noa i ngā paearu rerenga wai whare nui katoa.
He aha te pai ake o te rino maka EN877 i ngā rauemi rerekē
Haumaru Ahi: A1 Whakarōpūtanga Kore-Mumura
He rauemi kore-mura te rino maka i raro i te ASTM E136. E whakaaetia ana mō te whakamahi i roto i ngā wāhi tūmatanui, kāore he here. I raro i te paerewa EN877:2021 kua whakahoutia, me whakamahi ngā pūnaha waikeri rino maka i ngā paninga ātete ahi A1.
Ko te A1 te whakatauranga teitei rawa atu. He rerekē, he mura te PVC, ā, me whakamahi taputapu ārai ahi, kara rānei ina uru ki roto i ngā huihuinga e āhei ana ki te ahi.
Te Whakaari Oro: Te Whakatutuki i ngā Whakaritenga Haruru o ēnei Rā
I whakaurua mai e te EN877:2021 ngā whakaritenga whakamātautau mahi ārai haruru motuhake mō ngā pūnaha waikeri. Ka whakaitihia te haruru e te matotoru o ngā paipa waikeri rino maka—he mea nui tēnei mō ngā whare noho, ngā hōtēra, me ngā hōhipera, he mea nui te whakamarie o te hunga noho.
Ātete ki te pāmahana
Rauemi – Te Pāmahana Whakahaere Tonu Mōrahi
EN877 Rino Maka — 100°C me ngā gaskets ASTM C564
PVC DWV –140°F (60°C)
He maha ngā wā ka nui ake te pāmahana o te wai para o te kīhini i te taumata e 140°F mō te PVC, ā, ko te rino maka anake te kōwhiringa pono mō te waikeri o te kīhini arumoni.
Te Pūngao Rere: He Tātaitanga e Whakawhirinaki ana ki ngā Rauemi
He tirohanga nui mai i ngā rangahau IAPMO tata nei: he pānga nui te rauemi paipa ki te kaha rere mō te rahi paipa ingoa kotahi. Ko te kaha rere o te puranga poutū PVC 4-inihi he tata ki te 429 karani ia meneti, ko te paipa rino maka he rite te rahi he 172.5 GPM anake—he rerekētanga tata ki te 60%.
Ka puta tēnei nā te mea:
- He rerekē ngā diameter o roto o ngā rauemi rerekē
- Ka rerekē ngā tauwehenga taratara i runga i te rauemi
- He maha ngā waehere paipa e whakatakoto ana i ngā ripanga rahi ki runga i te rauemi kotahi, me te kore e tohu ko tēhea.
Mō ngā kaihanga waikeri: He iti noa te rere o te rino maka, ā, me nui ake pea ngā paipa i te PVC. Ka tautokohia e tēnei ngā pūnaha pono, ā, ka āwhina ki te ārai i ngā pakaru wawe. Ka puta pea ngā pakaru wawe ina kore e pai te whakakī i te PVC ngāwari.
Kaha Hanganga: Ngā Pūnaha Pūmau, Ngā Pūnaha Ngāwari rānei
He pūnaha paipa pakari te rino maka e tuku ana i te kaha hanganga pai, e whakaiti ana i te hiahia mō te whakairi me te whakarato i te hinganga pumau. Mō ngā whakaurunga o raro whenua:
- Kāore e hiahiatia he whāriki motuhake mō te rino maka; me pumau noa te raro o te rua
- Me whai tikanga whakakī anō motuhake te PVC e ai ki te ASTM D2321, tae atu ki te 4-6 inihi o te rauemi moenga, ka whakakīia ki ngā paparanga 6-inihi ki te 85-95% te matotoru.
- Mena kāore i te tika te tāutanga o ngā pūnaha PVC ngāwari, ka kiia kua pakaru i te rā tuatahi o te mahi.
Te Whakatutukitanga Paerewa
Kua hangaia ngā pūnaha waikeri DINSEN kia rite ki te EN877:1999 + A1:2006, te paerewa Pākehā e pā ana ki ngā wāhanga paipa rino maka mō ngā pūnaha tukunga wai whare mai i te DN40 ki te DN600. Nā te whakahoutanga hou o te EN877:2021 i whakapiki ake i ngā whakaritenga kaha kume mai i te 150 MPa ki te 200 MPa.
Rārangi Arowhai Whakatakotoranga mō ngā Kaupapa Waikeri Whare
I te wā e tautuhi ana i ngā pūnaha waikeri rino maka a DINSEN, whakaarohia ēnei tawhā tāutanga:
Ngā Whakaritenga o te Piki (Te Wairewa o te Āhuatanga Taumaha)
Te Pikinga Iti rawa o te Diameter Paipa
DN50 3.5% (35‰)
DN75 2.5% (25‰)
DN110 2.0% (20‰)
DN160 1.0% (10‰)
Te Wāhi Whakairi
- Ngā paipa whakapae: ≤2m
- Ngā paipa poutū: ≤3m
- Me whai pūmau whakapakari i roto i te 500mm o ngā tuke me ngā tī
Ngā Momo Hononga
- Momo W: Hononga rawhi kowiri tira—he pai mō ngā kaupapa whakahou me ngā wāhi kuiti (kāore e hiahiatia he mahi wera)
- Momo A/B: Ngā hononga whakarara mō ngā tono pumau teitei
DINSENE whakarato ana i ngā pūnaha waikeri rino maka e tutuki ana i te EN877. E whakaputa ana i te 1000MT o ngā paipa me te 200MT o ngā taputapu ia marama. Whakapā mai ki tā mātou tīma hangarau mō te tautoko i ngā whakaritenga motuhake mō te kaupapa.
