Ngā Whakaaro Matua

• Me tango te uira i roto i te 0.1 mm mō ngā hiri o te pūnaha waipēhi nā te mea ka puta te turuturu o roto o te uira toenga, ka pakaru wawe hoki te hiri i roto i ngā ara iahiko pēhanga teitei.
• Mā te tango ā-ringa i ngā hiri, ka eke te huringa o ia hiri ki te 20-40 hēkona i runga i ngā mowhiti-O paerewa me ngā hiri horoi, ā, e 40-50 ngā wā tere atu i te kuti ā-ringa.
• Ko te whakakorenga kiripaka i te -100°C ki te -130°C e taunakitia ana mō ngā hiri silicone me te waipēhi FKM he angiangi te kanapa i raro i te 0.3 mm e ātete ana ki te pakū ā-mīhini.
• Ka tukatukahia e te mīhini whakakore parahanga XCJ-G600 ngā puranga hiri waipēhi 15 kg mō ia huringa, he nui mō te neke atu i te 3,000 mowhiti-O mō ia nekehanga i ngā rahinga whakaputa paerewa.

Ko te pono o te pūnaha waipēhi e whakawhirinaki ana ki te pumau o te hiri. Mā te hiri kotahi kāore i oti te tango i te mura ka ngaro te pēhanga, ka poke te wai, ka pakaru hoki te wāhanga. Nā tēnei ka waiho te tango i te hiri rapa hei taahiraa nui i roto i te hanga wāhanga waipēhi. Ko te whiriwhiri i te tikanga tango me te whirihoranga mīhini ka pā tika ki te mahi hiri i te mara.

Nā te mea ka taea e te hiri waipēhi me te toenga mura 0.15 mm i runga i tōna ngutu hiri te whakaiti i te roa o te mahi tae atu ki te 40% ki te whakaritea ki te hiri kua wetekina tika — he mea nui te tango mura i roto i te hanga hiri.

E whakamārama ana tēnei tuhinga he aha i rerekē ai ngā paerewa tango hiri waipēhi i ngā wāhanga rapa whānui, me pēhea te whakatutuki a ngā mīhini tango hiri ā-ringa me ā-kirikiri i ēnei whakaritenga, me pēhea hoki te whiriwhiri i te tukanga tango hiri tika mō te hanga hiri.

He aha i hiahia ai ngā hiri waipēhi ki te whakakore i te pakaru kia pai ai te mahi a te pūnaha

Ko te ngutu hiri te mata tino hira o tētahi hiri waipēhi — ki te mau tonu he toenga mura i tēnei taha, ka pakaru pea te hiri i roto i ngā huringa mahi tuatahi e 500. Ka mahi ngā hiri waipēhi mā te pupuri i te taunga pokanoa whakahaeretia i waenga i ngā wāhanga tūmau me ngā wāhanga neke. Ka whakararuraru te mura pokepoke i tēnei taunga, ka hangaia he ara turuturu pai e karo katoa ana i te hiri.

Mō ngā tono waipēhi pēhanga teitei i runga ake i te 200 pae, e tohu ana te paerewa ISO 6195 mō ngā hiri horoi me te ISO 3601 mō ngā mowhiti-O i ngā rohe o runga mō ngā hapa o te mata. Ko te toenga uira e neke ake ana i te 0.1 mm i runga i te mata hiri ka kiia he kore e tutuki i ngā tono waipēhi. He paerewa tino pakari ake tēnei i ngā hiri tūmau, i ngā wāhanga rapa kore-hiri rānei.

I roto i ā mātou wheako whakaputa i te whakamātautau i ngā puranga hiri neke atu i te 500 puta noa i ngā kaihanga taputapu waipēhi, kua kitea e mātou ko ngā hiri kua wetekina tika he whakahekenga tere turuturu tata ki te 85% ki te whakataurite ki ngā hiri kua tapahia ā-ringa i roto i ngā whakamātautau ara iahiko 200-pae. I ahu mai ēnei raraunga i ngā whakamātautau whakaae wheketere i whakahaerehia kia rite ki ngā kawa whakamātautau ISO 10766 mō ngā hiri waipēhi tauutuutu.

Nā te ISO 1629 i whakatū te whakaingoa rapa mō te tautuhi rauemi. Nā te ISO 3601-1 i tautuhi ngā ine me ngā manawanui o te mowhiti-O e pā ana ki ngā paerewa kounga tango-rapa.

Mīhini Whakakore Ā-ringa mō ngā Hiri Rapa Waipēhi

Te whakakorenga ā-mīhiniKo te tikanga tino whānuitia mō te hanga hiri waipēhi nui-rahi nā te mea ka puta he hua ōrite me te utu iti mō ia wāhanga. Ka tukatukahia e te mīhini whakakore hiri ā-ringa XCJ-G600 he 15 kg o ngā mowhiti-O me ngā hiri mō ia huringa, me ia hiri ka tapahia i roto i te 20-40 hēkona. Ka taea e te mīhini kotahi te whakakapi i te 40-50 kaimahi whakakore hiri ā-ringa e pā ana ki te putanga o ia rā.

Ka whakamahia e te mīhini te mātāpono whakakore hauātea: ka taka ngā hiri i roto i te pahu hurihuri 600 mm i te wā e mimiti ana ngā pāpāho tere-teitei i ngā rauemi mura mai i ngā mata o ngā wāhanga. Ka mau tonu te tere o te pahu i roto i ngā kawenga puranga mai i te 5 kg ki te 15 kg. Mā te tikanga whāngai me te tuku aunoa ka taea te mahi tonu me te iti o te tirotiro a te kaiwhakahaere.

Mō ngā hiri waipēhi me ngā diameter o waho i waenga i te 3 mm me te 100 mm, ka taea e te XCJ-G600 te tukatuka i te whānuitanga rahi katoa me te kore e whakarerekē i ngā taputapu. He mea tino nui tēnei mō ngā kaihanga e whakaputa ana i ngā rahi hiri whakauru mō ngā whakaritenga pūnaha waipēhi rerekē. Mā ngā tawhā whakarerekētanga o te mīhini ka taea e ngā kaiwhakahaere te arotau i te wā huringa me te kaha o te pāpāho mō ia rauemi hiri.

Te Whakakore i te Hiri Cryogenic mō ngā Wāhanga Waipēhi Tika

Ka hiahiatia te whakakorenga kiripaka ina hiahiatia te tango i te mura i raro i te 0.1 mm i runga i ngā mata hiri. Ka whakamahia e te tukanga te hauota wai i te -100°C ki te -130°C hei whakakorikori i te mura angiangi me te pupuri i te ngāwari o te tinana hiri. Kātahi ka pakaru te mura pakarukaru mā te rauemi pupuhi me te kore he ahotea miihini ki te rauemi turanga.

Nā te mea kua piki haere te whakamahinga o ngā hiri waipēhi i hangaia mai i te FKM (fluoroelastomer) me te rapa silicone mō ngā tono ātete pāmahana teitei me te ātete matū, ā, nā te mea he iti ake te kaha haehae o ēnei rauemi i te NBR, i te PU rānei, nō reira ka āwhina te tukatuka cryogenic ki te ārai i te haehae o te mata i te wā e tangohia ana te hiri. Ka puta hoki i te tikanga cryogenic he mata maeneene ake i runga i te ngutu hiri, e whakaiti ana i te waku i te wā pakaru tuatahi o te mahi rango waipēhi.

Ko te painga matua o te whakakorenga o ngā mea i roto i te cryogenic deflashing ko te utu. Ko te kai hauota wai o te 20-50 kg ia puranga ka tāpiri i te $5-15 ki ngā utu tukatuka ia huringa. Mō ngā mowhiti-O paerewa me ngā hiri piston urethane, he pai te whakakorenga ā-ringa. Mō ngā tono hiri nui e tohua ana te kore ātete ki te mura, he pai te utu tāpiri mō te whakakorenga o ngā mea i roto i te cryogenic hei whakakore i ngā para me te mahi anō.

Whakataurite: Te Whakakore i te Hiri Ā-ringa me te Whakakore i te Hiri Waipēhi

Ko ngā whakatau tata utu e ahu mai ana i ngā tawhā whakaputa paerewa mō te tango i ngā hiri waipēhi. Ka rerekē ngā utu tuturu i runga i te āhua o te hiri, te matū rauemi, me te utu hauota wai ā-rohe.

Ngā hapa mura noa o ngā hiri waipēhi me te huarahi e whakatika ai ngā mīhini whakakore i te mura

Nā ngā hapa pokepoke i roto i te hanga hiri waipēhi ka puta he maha ngā momo uira e hiahia ana kia tangohia i mua i te mahi tika o te hiri i roto i te ara iahiko waipēhi.

Te whakarōpūtanga o ngā hapa uira i runga i ngā kitenga noa i roto i te whakahāngai kōpeketanga me te werohanga o ngā hiri waipēhi.

Te Whakauru i tētahi Mīhini Whakakore Hiri Rapa ki ngā Raina Hanga Wāhanga Waipēhi

A mīhini whakakore hiri rapaka taea te whakauru ki roto i tētahi raina whakaputa hiri waipēhi o nāianei me te iti o te whirihoranga anō. Ko te mīhini whakakore hiri ā-ringa XCJ-G600 he 1750 mm (R) x 1000 mm (W) x 1000 mm (T) te rahi, ā, ko te taumaha he 650 kg, e hiahiatia ana he tata ki te 2 mita pūrua o te wāhi papa. Mā ngā tikanga whāngai me te tuku aunoa ka taea te hono tika ki ngā taputapu whakairo o runga me ngā teihana tirotiro o raro.

Mō ngā raina whakaputa e tukatuka ana i te neke atu i te 10,000 hiri ia rā, mā te whakanoho i te mīhini whakakore i muri tonu i te mīhini whakakōkī me te teihana whakamatao ka hopukina ngā hiri i te pāmahana tino pai rawa atu. Ko te mea pai, me uru ngā hiri ki te mīhini whakakore i roto i te 30 meneti o te whakakorenga, i mua i te whakarerekētanga o ō rātou rahi e te whakahekenga i muri i te whakamaroke. He mea nui rawa tēnei matapihi wā mō ngā hiri waipēhi NBR me FKM e pāngia ana e te whakamomona tuarua.

E ai ki ngā paerewa tiaki mīhini OSHA 1910.212, me whakauru te mīhini tango i ngā panera urunga honohono me ngā mana aukati ohorere. Mā ngā pūoko mata maripi me ngā pūoko roera whāngai o te mīhini ka whakaratohia he tiaki tāpiri atu ki te kaiwhakahaere i te wā e utaina ana, e tangohia ana hoki.

Me pēhea te whiriwhiri i tētahi mīhini whakakore hiri rapa mō ngā mahi waipēhi

Ko te whiriwhiri i ngā taputapu tango hiri tika mō te hanga hiri waipēhi e whakawhirinaki ana ki ngā āhuatanga e whā: te rauemi hiri, te rahinga whakaputa, ngā whakaritenga tika, me ngā herenga tahua.

Kōwhiria te whakakorenga ā-mīhiniina whakaputa hiri NBR, EPDM, PU rānei i roto i ngā rahinga neke atu i te 5,000 waeine ia nekehanga. Ko te wā huringa hiri 20-40 hēkona o te XCJ-G600 me te tukatuka puranga aunoa e pai ai mō ngā mowhiti-O paerewa, ngā hiri horoi, me ngā hiri piston me te uira neke atu i te 0.2 mm. Ko te utu iti mō ia wāhanga ($0.003-0.008) he painga mō te whakaputa hiri taonga e aro nui ana ki te utu.

Kōwhiria te whakakorenga kiri-kirii te wā e hanga ana i ngā hiri FKM, silicone, HNBR rānei me te uira i raro i te 0.3 mm. Kāore e pai te aro o ēnei rauemi ki te pakū ā-mīhini nā te mea ka piko te uira angiangi, kaua e whati, nā te ngāwari o ēnei rauemi. Ka pakaru te uira i te tukatuka cryogenic i te -100°C ki te -130°C, kia kore ai e ma te tango, me te pupuri tonu i te āhua o te tinana hiri. Ko te utu nui ake mō ia wāhanga ($0.015-0.035) e tika ana mā te whakaiti i ngā reiti whakakorenga, e penapena ana i te 10-15% o ngā utu whakaputa katoa ina neke atu i te 8% ngā reiti hapa tuatahi.

Kōwhiria te tukatuka raupapaina whakaurua ngā hiri me ngā kōtaha uira whakauru ki te whakaputanga. Ka tangohia e te ara whakakorenga miihini te uira nui, ā, ka whai ake ko te tukatuka cryogenic mō ngā mata tino tika. He mea noa tēnei huarahi i roto i ngā kete hiri rango waipēhi e whakauru ana i ngā mowhiti-O paerewa me ngā hiri tokotoko tino tika i roto i te puranga whakaputa kotahi.

Whakatau: Te Whakataurite i te Tika o te Whakakore i te Pakaru ki ngā Whakaritenga Pūnaha Waipēhi

Ko ngā paerewa tango hiri pūnaha waipēhi e hiahiatia ana he nui ake i ngā paerewa tango hiri o ngā wāhanga rapa whānui nā te mea ka pā tika ngā hapa o te mata hiri ki te pupuri i te pēhanga o te pūnaha me te roa o te wā o te wāhanga. Ko te mīhini tango hiri rapa e tango ana i te mura pokepokea ki roto i te 0.1 mm i runga i ngā mata hiri te whakaritenga iti rawa mō ngā tono waipēhi neke atu i te 100 pae.

Mā te whakakorenga ā-mīhini ka iti rawa te utu mō te hanga nui o ngā hiri waipēhi NBR me te PU paerewa. Mā te whakakorenga cryogenic ka tika te mahi a ngā hiri FKM me te silicone i roto i ngā taiao waipēhi uaua. Ka whai hua ngā kaihanga e hanga ana i ngā hiri mō ngā tono waipēhi maha mai i te aromatawai i ngā hangarau e rua ki tā rātou kohinga hiri motuhake.
