Te pikau: hanganga, momo, tono.

Te pikau repe Ko te hiri noa, Kei te whakamahia nei mō te taatiraa ngā pūrere. tutuki ki te awhina o tona tightness te i roto i te hononga o ngā wāhanga: te parau tumu whakahaere o whakapanga ohie. E whakamahia kekeno kore anake i roto i ngā pūhanga o kōpuku pūkoro, engari mahi noatia e pateko taatiraa ki adhesions (hei tauira, i roto i putorino).

He aha te mea i roto i

Repe te pikau mumu o miro i te puka o te string o wāhanga tapawhā tapawha ranei. Tei runga i te tikanga o te tono (te pēhanga, kawenga hihiri, te pāmahana) gasket hanga i muka waro TRH, ake whakaū turanga o nga papanga o nga mea katoa o taura polytetrafluoroethylene (PTFE) ranei.

te wahi e whakamahia

Te pikau hoki repe whakamahia rite whakahuatia i runga ake, no te taatiraa:

• taiepa mamau pūmau, me te turanga;
• autoclaves;
• papua;
• compressors;
• mapuni;
• mihini me ētahi atu wae.

Ano i roto i nga mara o te ahumahi:

• production hau;
• hinu;
• tukatuka;
• kai;
• karihi.

taiao Whakahaere:

• hinu;
• korohū superheated;
• wai;
• hau (tae atu liquified);
• matū matū pukuriri;
• hua hinu.

āhuatanga

He nga āhuatanga faufaa e whai ake nei hiri repe:

• ātete matū (inertness) ki rerekē ngā āhuatanga pukuriri;
• mehua iti o te waku (whakaiti sino i roto i te hekenga uara o ngā wāhanga turanga o ngā tipu);
• radiation resistance;
• kaha;
• tapatahi;
• wera resistance;
• haumarutanga kaiao;
• whakakonekone ki hoholo (kore holomui i roto i te tiaki me te mahi);
• elasticity (whakahou o te whakamahi taputapu).

He aha ngā āhuatanga Me riro te pikau repe

Ko te ture tangohia whakaritenga motuhake i runga i te waea. Whakarārangitia i konei ko te nui tino.

1. kia matū hohekore te gasket. I te iti rawa, e kore e te rauemi raw ariu ki runga ki te whakapā ki te wetekina reo whakarerekē tona kounga taketake ranei. Hei tauira, ki te te whakamahia te tarapēke repe mō te taatiraa tāutanga (tīwae scrubber) i roto i nei he haurehu ha'iriiri, me te waikawa alkali ranei, ki te turanga hinu hiri e acid- me alkali-ātete. Ko te taua pā ki uglevodorozham (penehīni, hinu, greases). tino taea Tuhinga repe arahi ki te kore hiri, ati, mate o tauhohenga me na runga i.
2. Me te tu i te tapo'i repe pikau pāmahana teitei, me te pēhanga teitei. I roto i ngā nga pou Māturu o te hinu Māturu kawea i roto i te pāmahana teitei. Leakage taea arahi ki ino o te hanganga o nga hua Māturu, mumura, tuku o kohu ki te waho, me te noa pahūtanga.
3. Ki te whakamahia te hiri gasket ki ārahi i te ranunga, kia waiho ratou ātete ki te huri kawenga. Hei tauira, mō te taatiraa te papu neke wahi kia whai ātete ki frictions pouaka hau. I tua atu, me kia ātete ki te abrasion te gasket. Hoki tenei whakaaro, e tāpiri ratou e matū rerekē, pērā i Teflon.

E kore e tatou whakarerea e te ture

He ona ake paerewa production motuhake ia, te ara pai, ko te ki te whakamahi i me te tāuta i te hiri gasket. tūemi katoa ngā whakaritenga pērā i te take nui rite haumaru. Kore ki te ū ki te tikanga tāutanga (tūnga, te tightness o hononga, maha o mowhiti gaskets) me te mahi e taea hua i roto i te mau hopearaa tino kino. A pera kia whakaaro nga ngā katoa:

• ture mo te tono;
• kōwhiringa o te rauemi;
• hōtaka kekeno huringa tarapēke;
• Tāuta kōrero me ngā pūrere sealable.

Types packings

Mai te whakapanga iho, i roto i te meka, ko te aho i hanga o ngā papanga, te rerekētanga ka ngā reira anake i roto i te ripeka-wāhanga, te hanganga, me te hanganga o te raranga. Ko te pai mohiotia tito taua packings:

• graphite;
• papa kiripaka;
• ptfe;
• whakapanga o muka waihanga;
• papa kiripaka-free.

tarapēke graphite

Hanga o te konumohe whakapakaritia. Painga o enei gaskets ko e whai ratou iti kawe ia waiariki me te whakarea o te waku. Huakore - e kore e whakaaetia e ratou ki te whakamahi i roto i ngā taiao ki nohanga tiketike o te hauota, pūhaumāota me te chromium pūhui.

momo papa kiripaka

Tenei kekeno tarapēke whakamahia i roto i te taiao ha'iriiri, rite pakari reira ki te pāmahana tiketike me tenge. Ona tohu: AC, AP, AIR, AGP. Enei gaskets mahi i roto i te hinu, konganuku me te ahumahi hau, me te rite i roto i te ahumahi automotive.

ptfe

Ngāwari me te ātete ki ngā āhuatanga pukuriri. Ko te pau o enei mōkihi ko e kore ai te whakamahi ratou i roto i ngā taiao te wahi i reira he māota. E whakamahia ratou i roto i te ho'oraa, hinu, me te matū ahumahi.

Gaskets o kakawaea

He ātete ki te abrasion taua kekeno. E nana ratou i roto i te penupenu me te pepa, matū me te ahumahi hinu.

papa kiripaka-free

He kia kia ngā momo: etahi o ratou e whakapakaritia ki te waea parahi, a ka moe te tahi mau tāpiritanga i te ngako. Tei runga i te hōkai o te whakamahi o te tetahi momo tīpakohia te.

E ai ki te hanganga o te matua gasket rerekē ripeka-tapahi, maha-apa, me te kotahi-apa mumu. Papu tarapēke repe kia he wāhanga o 3 ki te 50 mm, i runga i tona whakaaro rānei.
