Hiri ngohengohe me te hiri mārō o te takirere pūrerehua

1. He aha te rerekētanga matua i waenganui itakirere pūrerehua hiri ngohengoheme te takirere pūrerehua hiri mārō?

He rerekē te rauemi o te mowhiti hiri. Ko te takirua hiri o te takirere pūrerehua hiri-ngohengohe he "nohoanga whakarewa + mowhiti hiri kore-whakarewa", ā, ko ngā rauemi e whakamahia whānuitia ana ko te rapa (EPDM/NBR), te polytetrafluoroethylene (PTFE), me ētahi atu, e whakaaturia ana i te Pikitia 01; ko te takirua hiri o te takirere pūrerehua hiri-mārō he "whakarewa ki te whakarewa", ā, ko te nohoanga takirere me te mata hiri he mea hanga i te kowiri tira, te maitai koranu, te mata carbide rānei. Ko te tuatahi ka tutuki te hiri mā te whakarerekētanga pīngore o te rauemi, ko te tuarua ka whakawhirinaki ki te miihini tika me te pēhanga reo hei whakatutuki i te hiri.

2. He aha te awhe pāmahana e tika ana mō ia mea?

Ko ngā hiri ngohengohe he mea here ki ngā rauemi kore-whakarewa: he pai te rapa EPDM mō te -40℃~120℃, ā, ka taea e te PTFE te eke ki te -40℃~200℃. Kāore he herenga pēnei mō ngā hiri mārō. He pai ngā takirere pūrerehua hiri mārō kowiri tira tuku iho mō te -40℃~425℃, ā, ka taea e ngā rauemi koranu motuhake te tu atu ki ngā pāmahana teitei i runga ake i te 600℃.

3. Ko tēhea te mahi hiri e pai ake ana?

He pai ake te hiri ngohengohe, ā, kāore e taea te turuturu (ANSI Akomanga VI). Mā te ngāwari o te rapa/PTFE ka taea te whakakī i te koretake o te mata whakarewa, ka tutuki hoki te hiri taumata-mirumiru. Nā te pā pakari o te whakarewa, ko ngā whakaritenga paerewa mō ngā hiri mārō ko te ANSI Akomanga IV~V (ka whakaaetia te turuturu iti rawa), he mea e tika ana mō ngā rauemi tukatuka he ātete ki te turuturu.

4. He aha te rerekētanga i waenga i te roanga o te ratonga me ngā utu tiaki?

He pakari ake ngā hiri mārō. He ngāwari te pakaru me te tawhito o te mowhiti rapa/PTFE hiri-ngohengohe nā te roa o te pirau me te whakawhiti pinepine. Me whakakapi te mowhiti hiri i ia 2 ki te 5 tau. I muri i te paninga o te mata whakarewa hiri mārō ki te carbide, ka ātete ki te pakaru me te pirau, ā, he roa ake te ora mahi neke atu i te 10 tau. He pai mō te whakarerekētanga auau o ngā āhuatanga mahi. Ahakoa he nui te utu tīmatanga, he iti ake te utu tiaki mō te wā roa.

5. He aha ngā rerekētanga o te urutau pāpāho?

Kāore te hiri ngohengohe e ātete ki te waikura kaha/ngā mea kei roto he matūriki. Ahakoa he pai te pumau matū o te rapa me te PTFE, ki te mea kei roto he matūriki mārō (pēnei i te paru, te paura waro), ka taea e ngā matūriki te rakuraku ngāwari i te mata hiri ngohengohe ina whakatuwheratia, ina katihia te takirere, ka puta he turuturu. He pai ngā hiri mārō mō ngā āhuatanga mahi uaua pēnei i te mamaoa pāmahana teitei, ngā hua hinu, ngā paru kei roto he matūriki, me ngā hau pēhanga teitei.

6. Whakamutunga

Ko te rerekētanga matua i waenga i te hiri ngohengohe me te hiri mārō o tetakirere pūrerehuaKei roto i te rauemi hiri: he pai te ngāwari o te hiri ngohengohe (rapa/PTFE), kāore e turuturu, ā, he pai mō ngā rauemi ma i te pāmahana rūma; ko te hiri mārō (mai i te konganuku ki te konganuku) he ātete ki te pāmahana teitei, ā, he ātete ki te kakahu, ā, he pai mō ngā āhuatanga mahi uaua pēnei i te mamaoa me ngā matūriki. He painga ō ia mea, ā, me whiriwhiri i runga i ngā āhuatanga mahi.Tianjin Tanggu Water-Seal Valve Co., Ltdhe tohunga ki te hanga ongā takirere pūrerehua, ngā takirere kuaha, takirere tirotirome ētahi atu momo takirere.
