Packings: āhuatanga momo me te tono

Packings - he hua e ngā nga pūtau repe. Ko te rauemi ko te aho rapa e kua he wāhanga tapawha porohita ranei. hanga te hua kei te o te papa kiripaka miro, me te tahi atu rauemi mata. Ka taea e Nā rauemi homai whakarato tightness pokarekarenga me pahoho pūhui tikanga. E pai te nohotahi aho mana o te taiao kaitaua, me te ātete ki huringa pāmahana. E ai ki te ahumahi o te rauemi hua e taea te whakarōpūtia ki kiripaka me te papa kiripaka.

kia Packings kia pai hiri wae i roto i tetahi wae engineering. Ka taea te wehea ratou ki maha momo me ngā akomanga. Ia o ratou kua he tetahi taumata, me te roa. Hei tauira, kia whakamahia ngā hua papa kiripaka i roto i ngā taputapu e tukanga hinu, me fetu'utaki hoki ki matū. whakamana tukanga tā Arā e te tikanga o poka motuhake.

kia ētahi hua Kei kanohi i roto i te hanganga o te muka graphite e kua moe ki te PTFE me whakapūmautia e te tikanga o te miro miro. E whakamahia taua packings ki hiritia te plunger me papua turai. E pai te ārai ratou leakage wai. Na e taea ki te whakahaere i te papua wera, me te whakaiti ratou kohi pūngao hua ano tuku. Ko te meka e whai ratou he iti whakarea o te waku. He painga o tuhinga graphite ko e he ratou rawa ātete ki tiketike pāmahana (e pā ana ki 550 nekehanga ), Chemical whakaeke. Heoi, e kore e taea ki te raro i te rauemi ki te haumākū mai taea whai wāhi i te reira ki te te waikura o whakarewa i roto i te tikanga.

He whaiaro-lubricated packings graphite. Whakamahia enei hua kia ki hiritia nga wahi e haere koe ki raro nga tikanga katoa pokarekarenga. Kei te maha tukanga tā e hiahiatia ana taputapu i roto i naianei o paipa wai pūnaha whakawera ranei. Ngā mihi ki kairīwhi taea e kore anake ki te aukati i te turuturu, engari ārai hoki tona takanga atu.

Ki te whakamahi koe i te pouaka hau pikau mo papua turai, he reira pai ki te whiriwhiri i te taura miro. kia haurangi mua-hua i roto i te hinu puoto, i roto i nei i reira e waiho he nui iti o te ware pi. Ko te painga o tenei rauemi, ko te e taea te tu i te reira tenge ake ki te 20 MPa me te pai mahi ona mahi i runga i te whānuitanga pāmahana whānui (i -40 ki te +100 nekehanga). Heoi, kei te hohoro whakangaromia nga hua i raro i te mana o kawakore me waikawa.

He whakatinanatanga ngā he hiri repe waerau, e hanga nei e hāngai ana i runga i fluoropolymer. Ka taea te hanga ratou i roto i te puka o mowhiti, tītipi Holy ranei. Ko tēnei rauemi he elasticity iti, kia i roto i te tua ki te whakamahi i hiri rapa. whakaratohia hoki rerekētanga o packings, i reira e te hunga i roto i i whakamahia hoki waea parahi.
