Mena kei te whakauru koe i tētahipapu korehau itiki roto i tētahi taputapu hauora, taputapu taiwhanga, tono ahumahi rānei, ko tētahi o ngā pātai tino nui ko: "E hia te kaha o te korehau ka taea e ia te kukume?" Ina koa, mō tētahipapu korehau diaphragm, ko te whakautu ka tautuhia e tōna pēhanga mutunga, he whakatakotoranga matua e whakatau ana i tōna whaitake mō tō kaupapa.

Ka whakamāramahia e tēnei tuhinga ngā āhuatanga e pā ana ki te taumata korehau o ēnei papu me ngā mea ka taea e koe te tumanako.

He aha te papu korehau Diaphragm?

Hepapu korehau diaphragmhe momo papu nekehanga pai e whakamahi ana i te diaphragm elastomeric wiri, ngā takirere tirotiro, me te rūma hei hanga i te korehau. Nā te whakamahinga maroke, kore hinu, he mea tino pai mō ngā mahi e tino hiahiatia ana te ma me te kawe.

Te Awhe Korehau Noa mō ngā Papu Diaphragm Iti

Ahakoa he rerekē ngā āheinga i runga i te tauira me te kounga, ko te nuinga o ngā waeine papu korehau iti o te momo diaphragm ka tutuki i te korehau mutunga (te pēhanga iti rawa ka taea e rātou te eke) i roto i te awhe e whai ake nei:

15 ki te 29.9 inihi o te Mercury (inHg) 50 ki te 760 Torr rānei -7 ki te -100 kPa (ine).

• Pito o Raro (Whakamahinga Whānui): ~15-20 inHg (-50 ki te -67 kPa). He mea noa i roto i ngā papu utu iti mō ngā mahi pēnei i te tango tauira hau, te momi ngāwari, te pupuri rānei.

• Teitei (Te Tohu Hauora me te Taiwhanga): ~22-29.9 inHg (-75 ki te -100 kPa). He papu mahi teitei ēnei e whakamahia ana i roto i ngā tono uaua pēnei i te tātari toto, te tātari, me ngā taputapu tātaritanga aunoa.

Mō te horopaki:

• Pēhanga Āhuarangi: 0 inHg (ira) 101.3 kPa rānei (tino)

• Te korehau tino pai: 29.92 inHg (ine) -101.3 kPa rānei (ine)

Ko te tikanga tēnei he kounga teiteipapu korehau diaphragmka taea te tango i te 95-99% o te hau i roto i te rōrahi hiri.

Ngā Take Matua e Whakawhāiti ana i te iti o te papu diaphragm

He maha ngā āhuatanga hoahoa ā-roto e kore ai e taea e te papu diaphragm te whakatutuki i te korehau tino pai:

1. Te Whai Hua o te Rōrahi me te "Rōrahi Mate": Kāore he papu e taea te tango katoa i te hau mai i te rūma pēhanga. He iti noa te hau e toe ana, e mōhiotia ana ko te "rōrahi mate," ka mau tonu i muri i ia whiunga, ā, ka whakawhanuitia anō, ka whakawhāiti i te pēhanga iti rawa e taea ana.

2. Te turuturu o te hiri me te takirere: Mā ngā turuturu moroiti i tua atu i te hiri o te diaphragm, i ngā takirere tirotiro rānei, ka taea e te hau te turuturu anō ki roto i te taha korehau. Ka whakamahia e ngā papu kounga teitei ngā wāhanga kua oti te hanga kia tika te mīhini me ngā rauemi pai hei whakaiti i tēnei.

3. Te Whakaputa Hau o ngā Rauemi: I raro i te korehau, ka taea e ētahi rauemi (pēnei i ētahi kirihou, rapa rānei) te tuku i ngā hau, i ngā kohu rānei kua mau i roto i ō rātou hanganga. Ka whai wāhi tēnei āhuatanga, e kiia nei ko te whakaputa hau, ki te pēhanga i roto i te pūnaha, ā, ka hanga he papa e kore e taea e te papu te wikitoria.

4. Ngāwari me te Hiri o te Diaphragm: Ko te ngāwari o te diaphragm tonu ka whakawhāiti i te ōwehenga kōpeketanga. Ka taea e te diaphragm pakari ake te hanga i te korehau kaha ake engari me whai motuka kaha ake, ā, he rerekē ngā taupatupatu roa.

Ngā tono mā te kaha korehau

• Korehau iti (15-20 inHg / -50 ki te -67 kPa): Ngā kapu momi hei pupuri, te whakaoho hau māmā, ngā putea tauira hau, ngā taputapu momi taketake.

• Pūwero Waenga (20-25 inHg / -67 ki te -85 kPa): Momi hauora, aroturuki toto, papu ū, whakahaere wai aunoa, mīhini tākai.

• Te Korehau Teitei/Hohonu (25-29.9 inHg / -85 ki te -100 kPa): Te tātari taiwhanga, te tango hau korehau, te whakahaere haurua-ira, ngā taputapu tātaritanga matatau.

Me pēhea te whiriwhiri i te papu tika mō ō hiahia horoi korehau

1. Tirohia te Pepa Whakatakotoranga: Rapua tonu te whakatauranga "Ultimate Vacuum" "Final Vacuum" rānei, e inehia ana i roto i te inHg, kPa, Torr rānei. Koinei te pēhanga iti rawa o te papu.

2. Whakaarohia te Tere Rere: Tērā pea ka tutuki i te papu te korehau hohonu, engari ki te iti te tere rere (CFM, LPM rānei), ka roa te wā e tae atu ai ki reira. He maha ngā wā me whakataurite te korehau mutunga me te tere.

3. Kia Mārama ki ngā Hiahia o tō Pūnaha: Me kaha te papu kia taea ai te whakakore i ngā turuturu i roto i tō pūnaha, me te whakatutuki tonu i te pēhanga mahi e hiahiatia ana mō tō tono.

4. Whakatairangahia te Kounga: Mō ngā tono nui, haumi ki tētahi papu mai i tētahi kaihanga rongonui e whakamahi ana i ngā takirere me ngā hiri kounga teitei hei whakarite kia tutuki tonu i tana mahi korehau kua whakatauhia.

Whakamutunga

Nō reira, e hia te iti o tepapu korehau iti o te diaphragmhaere? Ahakoa kāore e taea te whakatutuki i te korehau tino nui o ngā papu hurihuri nui, hiri-hinu, he tino kaha te papu korehau diaphragm kounga teitei, ka eke ki ngā taumata korehau tae noa ki te 29 inHg (-98 kPa). Nā tēnei ka waiho hei otinga kaha, ma, me te pono mō te whānuitanga o ngā tono hauora, ahumahi, me te taiwhanga. I te wā e whiriwhiri ana i tētahi papu, me āta whakataurite i ōna whakaritenga korehau me te tere rere ki ngā whakaritenga o tō pūnaha kia pai ai te mahi.
