He aha te takirere porowhita whakatītaha?
Ko ngā takirere porowhita he takirere kati-whakararangi e whakamahia ana hei tīmata, hei whakamutu, hei whakahaere rānei i te rere mā te whakamahi i tētahi wāhanga kati e kiia nei ko te kōpae. Kei waenganui, kei te whakarara hoki te nohoanga o te takirere porowhita ki te paipa, ā, ka katihia te whakatuwheratanga o te nohoanga ki tētahi kōpae, ki tētahi mono rānei. Ka taea e te kōpae takirere porowhita te kati katoa i te ara rere, ka taea rānei te tango katoa. Ka rerekē te whakatuwheratanga o te nohoanga i runga i te nekehanga o te kōpae, he mea tino pai mō ngā mahi e pā ana ki te whakahaere rere. Ko ngā takirere porowhita te mea tino pai, ā, he whānuitia te whakamahinga hei whakahaere, hei aukati rānei i te rere o te wai, o te hau rānei i roto i tētahi paipa hei whakawhāiti me te whakahaere i te rere o te wai, ā, e whakamahia whānuitia ana i roto i ngā paipa iti.
Takirere porowhita whakawhāiti Ko tētahi o ngā hoahoa rongonui o ngā takirere porowhita, mō te pūnaha US me te API. Ko te diameter o roto, ngā rauemi, te mata ki te mata, te matotoru o te pakitara, te pāmahana pēhanga, kua tautuhia e te ASME B16.34.
Hei tāpiritanga, i runga i te hoahoa o te nohoanga me te kōpae, ko te kawenga nohoanga oTakirere porowhita whakawhāitika taea te whakahaere pai mā te kakau wiri. Ko te kaha hiri o teTakirere porowhita whakawhāitihe tino teitei. Ka taea te whakamahi mō ngā mahi whakatā, whakatā hoki. Nā te poto o te tawhiti haere o te kōpae i waenga i ngā tūranga tuwhera me ngā tūranga kati,Takirere porowhita whakawhāitiHe tino pai ēnei mēnā me whakatuwhera, me kati pinepine te takirere. Nō reira, ka taea te whakamahi i ngā takirere porowhita mō ngā mahi maha.
teTakirere porowhita whakawhāitika taea hoki te whakamahi mō ngā mahi whakatere. He maha ngā tinana takirere kotahi-nohoanga e whakamahi ana i te hanganga kākahu, i te momo pupuri rānei hei pupuri i te mowhiti nohoanga, hei ārahi i te mono takirere, hei whakarato hoki i tētahi huarahi hei whakatū i ngā āhuatanga rere takirere motuhake. Ka taea hoki te whakarerekē ngāwari mā te whakawhiti i ngā wāhanga whakapaipai hei whakarerekē i te āhuatanga rere, hei whakarato rānei i te kaha iti.te rere, te whakaiti i te haruru, te whakaiti, te whakakore rānei i te pokanga.
Āhuatanga matua o te takirere porowhita Throttling
- 1). Ngā āheinga hiri pai
- 2). He poto te tawhiti haere o te kōpae (whiu) i waenga i ngā tūranga tuwhera me ngā tūranga kati,Ngā takirere porowhita ASMEhe mea tino pai mēnā me whakatuwhera, me kati pinepine te takirere;
- 3).Ka taea te whakamahi i te takirere porowhita ASME hei takirere aukati-tātari mā te whakarerekē paku i te hoahoa.
- 4).TAnei te whānuitanga o ngā āheinga e wātea ana i roto i ngā momo tinana tee, Wye, me te koki.
- 5).He māmā te mahi mīhini me te whakahou i te mata o ngā nohoanga, mō ngā momo kaupapa.
