Te Whakapānuitanga Hangarau: He aha i "Whakakapi" ai ngā Mita Wai Ultrasonic i ngā Mita Ā-ringa Tuku Iho? 3 Ngā Painga Matua kua Whakamāramahia

Ko tētahi o ngā ngoikoretanga tino nui o ngā mita wai miihini ko tōna ngāwari ki te heke te tika, inā koa i ngā āhuatanga iti te rere. Ka whakawhirinaki ngā mita miihini ki te hurihanga o ngā wāhanga o roto hei whakahaere i te tikanga tatau; i roto i te wā, ka taea e te waku mai i ngā wāhanga neke, te puranga paru, te pakaru rānei te whakaroa i te hurihanga o ngā wāhanga, ka arahi ki te iti o te tatau. Hei tauira, ko te taputapu e turuturu ana, ko te wharepaku puhoi rānei e turuturu ana - e 10% te nui o ngā para wai o te whare i ia tau, e ai ki te Kaunihera Wai o te Ao - kāore pea e whakaputa i te kaha e ranea ana hei huri i te impeller miihini, ka hua ake te whakamahinga wai kāore i tuhia.

Ka whakakorea rawatia tēnei raruraru e ngā mita wai ultrasonic. Ka mahi rātou i runga i te kaupapa o te "rerekētanga wā-haere": e rua ngā transducers ultrasonic ka tukuna, ka whiwhi hoki i ngā ngaru oro mā roto i te wai. Ina rere te wai, ka tere ake te ngaru oro e haere ana i te ahunga o te rere, ko te mea e haere ana i te ahunga o te rere ka puhoi ake. Ka tatau te mita i te tere rere mā te ine i te rerekētanga wā iti i waenga i ngā ngaru oro e rua - he tukanga kāore e hiahiatia he wāhanga neke. Mā tēnei hoahoa ka whakarite i te tika tonu ahakoa i ngā tere rere tino iti (tae atu ki te 0.01 m³/h) me ngā tere rere teitei, me te tawhā hapa o te ±1% anake, ki te whakaritea ki te ±2-5% mō ngā mita miihini. Mō ngā whare, ko te tikanga kāore he pire wai "huna"; mō ngā ratonga wai, ka whakaitihia te ngaronga moni whiwhi mai i te wai kāore i inehia.

He ngāwari noa iho ngā mita wai miihini ki te pakaru ā-mīhini nā te mea e neke ana ō rātou wāhanga. Ka mau pea te paru i roto i te wai puna (pēnei i te waikura, i te onepu rānei) ki roto i te impeller, ka aukati i te mīhini; ka pakaru hoki ngā taputapu me ngā peera ina huri tonu, ka puta he pakaru pinepine. Me whakakapi ngā mita miihini e ngā kamupene wai i ia 6-8 tau, ā, ko te tukanga tango, tirotiro, me te tāuta anō i ngā mita ka puta he utu mahi me ngā rauemi. I ngā tāone nui he nui te taupori, ka taea e tēnei mahi tiaki te whakararuraru i te tuku wai mō te wā poto, ka whakararuraru i ngā kaiwhakamahi.

He rerekē, ko ngā mita wai ultrasonic he hanganga "kāore e nekehia" e whakaroa ana i tō rātou roa, ā, e whakaiti ana i ngā hiahia tiaki. Ki te kore he impeller, he taputapu, he peera rānei e pakaru, ka taea e rātou te mahi pumau mō ngā tau 10-15 - tata ki te rua te roa atu i ngā mita miihini. Heoi anō, ko te hoahoa paipa o roto maeneene e ārai ana i te kohikohinga paru, ā, he ātete ki te waikura (ko te nuinga o ngā tauira e whakamahi ana i te maitai kore waikura, i ngā anga kirihou hangarau rānei). I kitea i roto i tētahi rangahau i te tau 2023 e te International Water Association, ko ngā ratonga wai e whakamahi ana i ngā mita ultrasonic i whakaiti i ngā utu tiaki mā te 40% ia tau, nā te mea he iti ake ngā whakakapinga me ngā whakatikatika e hiahiatia ana. Mō ngā ahumahi he nui te whakamahinga wai (pēnei i te hanga, i te ahuwhenua rānei), ko te tikanga hoki he iti ake te wā kore mahi mō te tiaki mita, e whakarite ana i te whakaputanga kore haukoti.

I tēnei wā o ngā tāone atamai, kua kore haere ngā mita wai miihini e rite ki ngā hiahia whakahaere wai o ēnei rā. Me pānui ā-ringa ngā mita miihini—he tukanga uaua, ehara i te mea he nui te wā e pau ana (ina koa mō ngā whare noho nui) engari he ngāwari hoki ki te hapa tangata (pērā i te tuhi hē i ngā tau). Kāore hoki i a rātou te kaha ki te tuku raraunga wā-tūturu, ā, he uaua ki ngā kamupene wai te aroturuki i ngā turuturu paipa, te kite i te whakamahinga rerekē, te whakatinana rānei i ngā utu wai hihiri.

He mea hanga ngā mita wai ultrasonic mō te whakaurunga atamai. He maha ngā tauira he kōwae whakawhitiwhiti kōrero kua hangaia ki roto (pēnei i a LoRa, NB-IoT, RS485 rānei) ka taea te tuku raraunga rere wā-tūturu ki tētahi tūāpapa kapua matua. Ka taea e ngā ratonga wai te aroturuki mamao i ngā tauira whakamahinga wai, te tautuhi i ngā turuturu i te wā-tūturu (mā te kite i ngā pikinga ohorere, ngā hekenga rānei o te tere rere), ā, ka tukuna atu he whakatūpato aunoa ki ngā kaiwhakamahi mō te whakamahinga rerekē. Hei tauira, ki te pakaru tētahi paipa i tētahi wāhi noho, ka taea e te mita ultrasonic te tuku tonu i tētahi tohu turuturu ki te ratonga, ka taea ai e ngā tīma whakatika te urupare i roto i ngā hāora - te whakaiti i te ngaronga wai. Hei tāpiri, mā ngā raraunga e kohia ana e ngā mita ultrasonic ka taea e ngā ratonga te whakatinana i te whakahaere taha-tono, pērā i te utu wai i te wā pīki, hei whakatenatena i te tiaki wai. Mō ngā whare, ka tukuna hoki e ngā mita ultrasonic atamai he whai wāhitanga: ka taea e ngā kaiwhakamahi te tirotiro i tā rātou whakamahinga wai wā-tūturu mā tētahi taupānga pūkoro, hei āwhina i a rātou ki te whakarerekē i ngā tikanga whakamahinga me te whakaiti i ngā pire.

Ehara ngā mita wai orooro i te "whakakapinga" noa iho mō ngā mita miihini tuku iho—e tohu ana i te nekehanga ki te ine wai atamai ake, pumau ake. Mā te tino tika ka whakakorea ngā para huna, ka whakaitihia ngā utu tiaki e te roa o te ora, ā, mā te hototahi atamai ka whakamanahia te whakahaere wai e ahu mai ana i ngā raraunga. I te mea ka piki haere te korenga o te wai o te ao, ā, ka haere tonu te horapa o ngā tāone atamai, ka whai wāhi nui ngā mita wai orooro ki te whakapai ake i te whakamahinga rauemi wai. Mō ngā ratonga wai me ngā whare noho, ehara i te mea he kōwhiringa pai noa iho te awhi i tēnei hangarau—he taahiraa ki te tiaki wai kawenga.
