Ko te mahi me te roa o te ora o tētahi papu DC iti e whakawhirinaki ana ki te rauemi i whakamahia i roto i tōna hanganga. He rerekē i ngā papu ahumahi nui, he ngoikore ngā wāhanga iti o ngā papu iti ki te waikura, te horo matū me te kakahu. Ko te whiriwhiri i te rauemi tika ehara i te mea ko te roa anake, engari ko te whakarite kia mahi pai tonu te papu, inā koa ka mahi ki ngā wai motuhake, ki ngā taiao pāmahana teitei, ki te pehanga teitei rānei. Mena kei te whakauru koe i ngā papu puku iti ki roto i ngā taputapu hauora, ki...ngā papu pēhanga teitei itihei whakauru i ngā pūnaha ahumahi, he mea nui te mārama ki te pūtaiao rauemi.

Te Tūranga Hiranga o ngā Rauemi i roto i ngā Papu Moroiti

I roto i te papu wai iti, ka pā noa te wai ki ētahi wāhanga matua: te anga papu, te impeller/diaphragm, me ngā hiri. Me āta whiriwhiri te rauemi o ia wāhanga i runga i te wai e papuhia ana, te pāmahana whakahaere, me te pēhanga e hiahiatia ana.

Hototahitanga Matū

Koinei te mea tino nui. Mā te pupuhi i tētahi wai kaha matū (pērā i te waikawa kaha, te turanga, te whakarewa rānei) mā roto i tētahi kirihou, i tētahi elastomer rānei kāore e hototahi ka tere te pakaru, ka pupuhi, ka memeha rānei ngā wāhanga papu.

Ātete ki te pāmahana

Ko ngā whakamahinga pāmahana tiketike, pērā i te tohanga wai wera i roto i ngā papu moroiti o te whare, me whai rauemi hei pupuri i te kaha ā-pūkaha me te pumau o ngā āhuatanga. Ka taea e ngā kirihou noa te whakangawari, te whakapē rānei, ka arahi ki te turuturu me te heke o te mahi.

Ātete ki te pakū

Mena kei roto i te wai ngā matūriki whakakoi (paraoa paru, paru), me hanga ngā mata o roto o te papu, inā koa te impeller me te anga, mai i ngā rauemi mārō, ātete ki te kakahu hei pupuri i te rere me te pēhanga i roto i te wā.

Ngā Rauemi Noa me ā rātou Whakamahinga

Ko ngā papu wai moroiti he mea whakamahi i te huinga o ngā kirihou, ngā konganuku, me ngā elastomers.

Kirihou mō ngā Pouaka me ngā Impeller

Polypropylene (PP): He ātete matū tino pai ki ngā waikawa me ngā kawakore maha, ā, he iti te utu mō ngā papu iti. He kōwhiringa pai mō te kawe i te wai whānui me ngā matū ngawari. Polyphenylene sulfide (PPS): Ki te whakaritea ki te polypropylene, he ātete pāmahana me te matū tino pai. He maha ngā wā ka whakamahia i roto i ngā tono pāmahana teitei, hei kawe rānei i ngā matū waikura. Polyetheretherketone (PEEK): He kirihou mahi teitei me te kaha miihini tino pai, te ātete matū, me te pumau pāmahana. He pai mō ngā tono uaua, inā koa mō ngā huihuinga papu pēhanga teitei iti.

Ngā Elastomers mō ngā Diaphragms me ngā Seal

Ka whakamahia te elastomer mō ngā mowhiti-O, ngā gaskets me ngā diaphragms o te papu diaphragm iti. EPDM: He tino ātete ki te wai wera, te mamaoa me ngā whakarewa polar, ā, he mea whakamahi noa i roto i te umanga kai me te inu. Ko te rapa fluorine (Viton, e mōhiotia ana ko te rapa fluorine FKM): he tino ātete ki ngā wahie hinu-hinu, ngā hinu me ngā momo matū waikura, koia te rauemi nui mō te tuku papu wai kore-wai. Rapa silicone: he pai mō ngā wā e hiahia ana ki te ngāwari teitei me te ātete pāmahana tino nui, engari kāore i te pai mō ngā matū waikura.

Ngā konganuku mō ngā pou motuka me ngā whakapiri

Ahakoa ehara i te mea whakarewa ngā awa wai, ko ngā toki motuka he mea hanga ki te kowiri tira. Kowiri tira (304/316): He pai ake te ātete o te kowiri tira 316 ki te waikura i te kowiri tira 304, nō reira koia te rauemi pai mō ngā toki papu pērā i ngā papu iti DC 12V ka pāngia pea e te waikura mākū.

Kōwhiringa Rauemi mā te Taupānga

Ko te kōwhiringa o ngā rauemi ka whakawhirinaki ki te whakamahinga motuhake o te papu wai moroiti-ā-hiko.

Ngā Taputapu Whare (hei tauira, Ngā Mīhini Kawhe)

Me whakamahi i ngā rauemi e ātete ana ki te pāmahana teitei, he mea hanga mai i te kai (hei tauira, ngā hiri EPDM, ngā anga PPS) hei whakahaere i te wai wera, hei whakatutuki hoki i ngā paerewa haumaru. Me whakauru hoki he rauemi whakaiti haruru ki roto i tētahi papu wai iti e kore e whakarongo ki te reo.

Te Inenga/Te Tātari Matū

E hiahia ana kia tino hototahi ki ngā matū. Ko ngā papu e whakamahia ana i konei, pērā i te papu wai diaphragm iti, e hiahia ana ki ngā diaphragm PTFE (Teflon) me ngā hiri Viton hei whakahaere i ngā pāpāho kaha.

Ngā Pūnaha Pēhanga Teitei

Me whakamahi ngā rauemi kaha ā-ringa (pēnei i te PEEK, i ngā kirihou whakapakari rānei) hei tu atu i te ahotea tonu, me te kore e ngatata, e memeha rānei, hei papu pēhanga iti.

Ngā Pūrere Kawe

Me aro nui ki ngā kirihou mama, pakari hoki e āhei ana ki te tu atu i ngā maturuturunga me ngā pānga ki tētahi papu wai hiko moroiti 6 ngaohiko e whakamahia ana i roto i tētahi taputapu kawe.

Mōta Pincheng: Te Painga o te Whakaritenga Rauemi

Ko ngā papu iti noa e wātea ana i te mākete he mea hanga i ngā rauemi paerewa, iti te utu, ka pā pea ki te mahi me te roa o te ratonga i roto i ngā tono motuhake. Ko tō mātou kaha kei roto i tō mātou māramatanga hohonu ki te pūtaiao rauemi me tō mātou whakapau kaha ki te whakarite. Ehara i te mea ko te hoko noa i te papu wai dc iti mātou; ko tā mātou i hoahoa ai he otinga wai.

Tohungatanga Hototahi Wai

Ka mahi tahi mātou me ō mātou kiritaki ki te tātari i te hanganga matū, te pāmahana, me te pēhanga tika o tā rātou whakamahinga. Mā tēnei ka taea e mātou te whiriwhiri tika i te huinga kirihou, elastomer, me te konganuku tino pai, kia roa ai te ora me te pono mō ia papu wai iti kaha e hangaia ana e mātou.

Te Hanga Tika

Mā ā mātou tukanga hanga ka taea te hanga me te huihui i ngā rauemi mahi-teitei me ngā āheinga pakari, he mea nui tēnei hei pupuri i te whai huatanga o te papu pēhi wai moroiti.

Te Pono mō te Wā Roa

Mā te whiriwhiri i ngā rauemi tika, ka whakaitihia e mātou te mōrearea o te pakaru o te wāhanga, ka whakarite kia mau tonu te mahi a tō papu wai iti DC 12V puta noa i tōna oranga mahi, ā, he pai ake te uara i tētahi atu papu iti ake te utu, kāore i te roa te ora.

Whakamutunga

He mahi uaua engari he mahi nui te whiriwhiri i te rauemi tika mō te papu DC iti i roto i te whanaketanga hua. Me āta whakaaro ki te hototahitanga matū, te pāmahana me te ahotea miihini. Ahakoa he papu wai hiko iti 6-volt tāu e hiahia ana mō ngā taputapu kawe, he papu wai puku iti rānei mō ngā taputapu kāinga, mā te whiriwhiri rauemi koe e hanga, e pakaru rānei. I roto i te mahi tahi me Pincheng Motor, mā te ranunga tino pai o te pūtaiao rauemi me te hangarau tika ka tino pai te mahi a tō papu wai iti i roto i te taiao e hiahiatia ana. Kaua e whakaiti i te rauemi; Kōwhiria a Pincheng mō te otinga pumau.
