Ngā Ngongo Waipēhikei ngā wāhi katoa ngā Pūnaha, me mōhio noa koe ki hea e titiro ai. Ki te kite koe i ngā oko hanga karaka, kāti'Kei te titiro anō hoki ahau ki ngā taputapu kua whakakiia ki ngā pūnaha waipēhi. He mīhini tapahi tarutaru kore-hurihuri? Ae. He taraka para? Ae anō. Ngā pēki i runga i tō waka, te piko o tō motuka o waho, i roto i tētahi wheketere hanga....kei ngā wāhi katoa rātou.
Ka whakamahia e ngā ngongo waipēhi, ngā pūnaha rānei he wai waipēhi pēhanga hei whakaputa mahi i roto i tētahi pūnaha mīhini.'Ka tirohia e tātou ētahi kaupapa matua. Ko te wai waipēhi he wai kore e taea te pēhi, he mea hanga ki te hinu, ki te wai rānei. Nā te mea he kore e taea te pēhi, ka taea e ia te whakawhiti pūngao mai i te papu me te tuku atu ki te motuka, ki te rango rānei. Hei whakaahua i te pūnaha waipēhi, me...'Ka kōrero tātou mō te mea tino māmā: he wehewehe rākau. Ka kukume te papu i te wai mai i te puna wai mā te raina whakahoki, ā, ka pēhia. Ka tukuna te wai pēhanga mā te ngongo waea-rua, ā, ka mahi ki runga i te rango me te poro, ka pana i te rākau tae noa ki te pakaru. I te hokinga o te piston, ka panaia e te rango te wai ki muri mā te ngongo whakahoki ki roto i te puna wai hei whakamatao, hei whakarite hoki mō te huringa e whai ake nei. Ko tēnei pūnaha—puna wai, papu, rango me te ngongo—ko te pūnaha waipēhi.
Pūnaha Waipēhi
Mā te mōhio ki ētahi kōrero mō tō pūnaha ka āwhina i a koe ki te whakatau ko tēhea ngongo tika. Kāore i te tino uaua te whiriwhiri i tētahi ngongo waipēhi ina...kua tīmata te mārama ki ngā kōwhiringa maha me te take i wātea ai.
I tētahi taha, he tini ngā whakaritenga mō ngā ngongo waipēhi i hangaia e tētahi kaihanga. Āe, e 19 ngā whakaritenga mō te SAE 100R me ētahi whakaritenga mō te EN Pākehā. I tētahi atu taha, koia tēnei.He tino māmā noa iho. KoeE toru ā mātou kōwhiringa: he rapa me ngā waea whakarewa, he kirihou wera me te whakakaha kakahu, he Teflon rānei me te whiri kowiri tira. He iti noa atu ngā whakaritenga motuhake mō te tono, ā, ko mātouKa kōrerohia e au ā muri ake nei, engari, koinā tonu āu kōwhiringa e toru. Kia mōhio koe ki tāu e hiahia ana, ka whakatauhia te toenga.
I mua i tō tātou tīmatanga, me mōhio koe ki ētahi mea whānui. Tuatahi, ko ngā tau wāhanga o te ngongo waipēhi e tohu ana i te diameter o roto mā te whakamahi i te pūnaha 1/16. Hei tauira, ko te -04 he 1/4''te whānui o roto, te ID rānei (4/16=1/4), ā, ko te -12 he 1/4''(12/16=3/4) me ērā atu anō. Nō reira, ko te tau wāhanga pērā i te H28006 he rite ki te H280 me te rahi o te ngongo, 06 rānei, 3/8'' ID
Muri iho, ko te whakatauranga o te ngongo waipēhi i runga i te tauwehenga haumaru 4:1. Ko te tikanga ka pahū te ngongo 3,000-psi i te 12,000 psi, neke atu rānei. Ko ētahi o ngā mea kāore i te tino pai ko te ngongo pīka he tauwehenga haumaru 2:1, nā te mea he tono pumau, he iti hoki te ahotea. Pātai atu ki ā mātou Tohunga Ngongo mēnā kei a koee āwangawanga ana mō te āhuatanga haumaru.
Ko te hanganga whānui o te ngongo waipēhi he ngongo, he whakakaha, me te taupoki. Ko te ngongo te taha o roto o te ngongo e kawe ana i te wai waipēhi. Kātahi ka whai whakakaha; mā tēnei ka whakarato i te kaha me te pupuri i te pēhanga. Ko te mea whakamutunga ko te taupoki. Ko te taupokiKo tā te mahi he tiaki i te papa whakakaha mai i te pakaru me te waikura.
Ngā Momo Hanganga
E toru ngā momo hanganga matua mō te taha pēhanga o tētahi pūnaha waipēhi, me tētahi mō te taha whakahoki. Ko ngā ngongo mō te taha pēhanga o tō pūnaha ka hangaia i te rapa, te kirihou wera, te Teflon rānei.
rapa
Ko ngā ngongo waipēhi rapa he mea hanga i te rapa nitrile nā te meaHe hototahi ki te nuinga o ngā wai waipēhi. Ka taea e ngā ngongo rapa te whai whiri kakahu mō ngā tono pēhanga iti iho i raro i te 1,000 psi, he waea maitai kume teitei rānei mō ngā pēhanga tae atu ki te 7,000 psi me tua atu. Ko te momo waea kua whakapakarihia te mea tino noa. Kei roto i ngā hanganga mai i te paparanga kotahi ki te ono o ngā paparanga whakapakari.
Ko ngā taupoki he mea hanga i te rapa hangarau he pai ki te tu atu i ngā āhuatanga o te rangi me te pakū. Ko ētahi kaihanga e hanga ana i ngā ngongo he tino pakari ngā taupoki mō ngā mahi e hiahia ana kia tino tiakina te pakū; tera pea he paninga UHMW ēnei hei tu atu i te pakū kaha me te pānga.
Kirihou wera
Ko te tikanga, he ngongo nairona tēnei, he muka whakakaha hangai, me te uhi polyurethane. He maha ngā whakamahinga o te ngongo thermoplastic i roto i ngā pūnaha waipēhi whānui, te whakahaere rauemi, ngā forklift, me ngā pūnaha hiko tata. Ka taea e ia te whakahaere i ngā pēhanga rite ki ngā ngongo 1- me te 2-waea engari ka tāutahia ki ngā tono kāore e mahi he ngongo rapa me te whakakaha waea. He tino pai te mahi a te uhi polyurethane ina pāngia e te kutikuti o te sheave i runga i te forklift. I ngā āhuatanga e pāngia ana te hiko, pērā i roto i te hiki peere hei whakatika i ngā raina hiko, he pai rawa te ngongo thermoplastic kore-arataki.
PTFE:
I hangaia ki tePTFE whakakaha ngongo me te whiri kowiri tira, kāore e hiahiatia he taupoki nā te mea kāore te whiri kowiri tira e waikura i raro i ngā āhuatanga noa. Ka whakamahia te ngongo Teflon i ngā tono e hiahia ana ki te ātete ki te waikura, te hototahi matū, te wāhi rānei e āwangawanga ai te pāmahana teitei. He 450 tōna°Whakatauranga F.
Ētahi mea hei maumahara māu i te wā e tautuhi anaPTFE e pā ana te rahi me te whānui o te piko o te ngongo. Ko te rahi he 1/16 inihi te nuinga o te wā.he iti iho i te tohu o te tau wāhanga. Hei tauira, ko te ngongo -04 he 3/16''ā, ko te -06 he 5/16 inihiNō reira, ahakoa ka mutu tō tau wāhanga ki te 04, ehara i te mea ko te ngongo he 1/4 inihi te rahi.. He pono tēnei mō ngā rahi katoa. Mō te pūtoro piko, kia mahara ki tēnāPTFE He ngongo kirihou mārō te ngongo kua hipokina ki te whiri. Ki te pikohia e koe te ngongo kirihou mārō kia piko rawa, kaKua pakaru tō ngongo, ā, kua waiho hei ngoikore. Kia tūpato ina whakatakotoria ana ki ngā wāhi kuiti.
Whakahokia–Ngā Ngongo Waipēhi
He ngongo waipēhi te raina whakahoki e taea ai te momi, ā, e whakahoki ana i te wai waipēhi ki te tīmatanga o te pūnaha. Ko tēnei momo ngongo he ngongo rapa, he whiri kakahu hei tautoko i te pēhanga pai, me te waea porowhita hei āwhina i te momi.
Ngongo Taraka–Ngā Ngongo Waipēhi
Ko te ngongo taraka he wāhanga motuhake i roto i te whānau ngongo waipēhi. E whakamāramahia ana e te SAE 100R5 he uhi papanga, he ngongo waea-kotahi e whakamahia ana i runga i te maha o ngā pūnaha i roto i ngā waka i runga i te huarahi. Pērā i te ngongo Teflon, kāore te rahi o te ngongo taraka e whai i te huarahi paerewa 1/16 e whakamahia ana e te ngongo waipēhi paerewa. Ko te ID ngongo tuturu he 1/16''.to ⅛''iti ake i runga i te rahi. Anō, waea atu ki ngā Hose Pros i Besteflon, ā, mā mātou'Mā tēnei koe e āwhina ki te mārama ki te ngongo 100R5.
Ka hipokina e tēnei te nuinga o ngā kaupapa matua o ngā ngongo waipēhi. Mēnā ka hiahia koe ki te keri hohonu ake, me te uru atu ki ngā mahi taipitopito, waea atu ki tētahi o ā mātou Tohunga Ngongo iBesteflonā, mātouKa koa ki te āwhina.
