Ngā Pūrongo - Te Rawhi Ngongo Tauhou Tiamana vs Ngā Rawhi Noke Paerewa: He aha i Pai ake ai te Hiri o ngā Rawhi DIN3017

Kua tae kē koe ki reira. Ka whakamātau koe i tētahi mea noatopenga ngongo puku noke, ka rongo i te ngau, kātahi ka kite i te rapa e pupuhi ana i te taha o te whare. Tērā pea he kino ake, ka puta he pata wai whakamatao i raro i te motuka i te wiki i muri mai. He onge noa iho tēnei hei raruraru ngongo. He raruraru āhua kōpiri.

Ko te nuinga o ngā rawhi noke whānui e whakamahi ana i tētahi whitiki ōrite me tētahi whare roa. Ina hurihia te tīwiri, ka piko paku te whare, ka kumea te whitiki ki tētahi taha. Ka hangaia he mowhiti pēhanga kāore i te ōrite ka taea te kōpeke i ngā ngongo ngohengohe, te tapahi i te silicone, me te waiho i ngā ara turuturu iti. Ka kino ake te wiri o te miihini i te roanga o te wā.

Koinei tonu te mea i hangaia ai te rawhi ngongo rerekē momo Tiamana (DIN3017) hei whakatika.

He aha te tikanga o te "Eccentric" i runga i te rawhi

Ko te kupu "rerekē" i konei ehara i te mea rerekē. E pā ana ki tētahi ringaringa hononga kore taurite. He poto ake te whare, ā, ka whiti te whitiki i roto i taua whitiki i tētahi koki iti. I te whakakotahitanga me te āhua pewa pūkohu, ka kukumea te whitiki kia ōrite ki te ngongo katoa — kāore he piko, kāore he wāhi wera. Kia pēhia ki raro, ka noho papatahi te mowhiti mau. Ka huri te rawhi hei porowhita tūturu, ehara i te porowhita e pēhi kaha ana i ngā taha e rua.

Mō tētahirawhi ngongo whakamahana, he nui rawa tēnā. Kāore e taea e ngā kaki kirihou o te radiator me ngā ngongo rapa tawhito te tu atu i te pēhanga ngau kore taurite. Ka horahia e te Tiamana eccentric te kawenga me te hiri me te kore e kuru.

He mea nui te maitai – 304, 430 rānei te kowiri tira?

He nuingā rawhi ngongoWhakamahia ngā tīwiri whakakikoruatia ki te konutea me ngā whitiki kowiri tira 430 hei whakatutuki i te utu tika. He pai tēnā mō ngā paipa o roto. I raro i te taupoki, me hiahia koe ki tētahi rawhi ngongo kowiri tira e kore e waikura, e ngaro rānei te taipana i muri i ētahi huringa wera. E rua ngā momo e puta pinepine ana:

SS304– He pai ake te ātete ki te waikura. Kōwhiria tēnei mō ngā raina whakamatao, mō te whakamahinga moana, mō ngā hononga waipēhi o waho rānei.

SS430– He kaha ake te kume, he aukume, ā, he iti ake te ātete ki te tote. He kōwhiringa pai tēnei mō ngā paipa whakauru hau me ngā here mīhini maroke ina he mea nui te tahua.

He maha ngā kaihanga e whakamahi ana i tētahi whakatakotoranga whakauru: he whitiki 304 me te whare me te tīwiri konutea mō ngā āhuatanga taurite, he 304 katoa rānei mō ngā taiao haumākū teitei. Ko te mea nui ko te mōhio ki ngā mea kei roto i te rawhi, kaua e whakawhirinaki noa ki te mata kanapa.

Te Wāhi e Kitea ai te Rerekētanga o ngā Kutukutu Tiamana

He paerewarawhi nokeHe pai te mahi i runga i te ngongo māra, i te aho whakahoki pēhanga iti rānei. Ka mau tonu te hoahoa Tiamana ina piri, ina wera hoki ngā mea:

Ngā ngongo whakamatao me te radiator– Ahakoa te pēhanga o ngā paipa kirihou ka whakaiti i te tūponotanga o te ngatata, te turuturu makariri rānei i muri i te pāka hotoke.

Ngā paipa turbo me te utu– Ka ngana ngā ngongo silicone whakarei ki te pana atu. Ka kaha ake te pupuri a te DIN3017 i te taipana whakangaro me te mowhiti piri papatahi me te kore e tapahia.

Ngā wāhi kuiti– Ka paheke te ringaringa poto o te whare me te whānui o te whitiki 9mm ki ngā wāhi e kore e matara te whare tīwiri matotoru.

Ngā mīhini kawe waka– Ko te wiri tonu me te piupiu wera e hiahiatia ana he topenga ngongo kowiri tira e mau tonu ana, kaua e whakamuri i te hauwhā hurihanga i ia wā ratonga.

Me pēhea te whakatau i te rahi o te rawhi me te kore e whakaaro noa

Kaua e aro ki te tikanga "kotahi te rawhi e pai ana mō te nuinga". Inehia te diameter o waho o te ngongo me te ngongo kua tāuta ki te hononga. Kātahi ka whiriwhiria he rawhi kei waenganui i te awhe tō ine. Hei tauira, ki te 35mm te OD o tō ngongo, ka taea te whakamahi i te rawhi 25–40mm, engari mā te 32–50mm ka nui ake te wāhi whakatikatika me te hiri pai ake i te pito hiku o te whitiki. Kei te tūtohi rahi mō ngā rawhi ngongo DIN3017 e whakarārangi mārama ana i ngā awhe, kia kore ai koe e waiho hei whakatau tata.

He mea nui anō hoki te whānui o te whitiki. He pai ngā whitiki 9mm mō ngā hononga werowero me ngā paipa poto. Mā ngā whitiki 12mm ka whānui ake te wāhi nohoanga mō ngā ngongo silicone ngawari ake, ngā ngongo whakamatao nui ake rānei. E wātea ana ngā mea e rua heingā topenga ngongo kowiri tirai roto i ngā huinga rauemi maha.

Ngā Āhuatanga Tāutanga e Ārai ana i ngā Hokinga Mai

Ahakoa te topenga pai rawa atu, e kore e taea te whakaora i tētahi tāutanga kino. E whai hua ana kia whakamahia ēnei tikanga:

Whakanohoia te whare ki runga i te wāhanga tika o te ngongo, kaua ki te piko, kaua rānei ki runga tonu i te ngutu taratara.

Whakamahia he taraiwa whakawhāiti taipana mēnā kei te mahi koe me ngā putanga kirihou o te radiator. He nui te 3–4 Nm i te nuinga o te wā.

I muri i ngā huringa wera tuatahi e rua, tirohia te rawhi. Ka pēhia te silicone; mā te hurihanga iti ka ārai i te pakaru.

Ki te mea he kirikiri te tīwiri i te wā e whakamārō ana, whakahokia te tīwiri, tirohia mēnā he miro e pāngia ana — ka taea e ngā tīwiri kowiri tira te pāngia. Mā te paninga iti o te ārai-hopu ki ngā miro ka whakakorea.

Te Raina Taketake

Kāore tēnei e kī ana he koretake te topenga noke noa. Arā, ina he mea nui te hononga — he whakamahana he uaua ki te toia, he paipa turbo kāore koe e hiahia kia pupuhihia, he ngongo ahumahi uaua ki te toro atu — he mahi mohio te hoahoa DIN3017 rerekē Tiamana. He nui ake te utu i mua, ā, ka utua koe mā te kore e turuturu, e kore e wetekina, e kore hoki e kai i te ngongo i roto i te wā.

Ki te whakakīia tō toa ki ngā rawhi ngongo whakamahana me ngā rawhi ngongo kowiri tira e hiri porowhita ana, ka iti ake te wā e pau ki te whai i ngā maturuturunga iti, ā, ka nui ake te wā e pau ki te whakaoti i te mahi.
