Kutsatira Malamulo ndi Miyezo: "Njira zotsatirazi zowongolera mapampu osinthika a DC apangidwa mogwirizana ndi miyezo yapadziko lonse yachitetezo ndi magwiridwe antchito, kuphatikiza IEC 60335-2-41 (Chitetezo cha Mapampu) ndi CE Low Voltage Directive (2014/35/EU). Miyezo iyi ikutsimikizira kuti njira yathu yaukadaulo ikukwaniritsa zofunikira zolimba za machitidwe oyang'anira madzi m'mafakitale ndi m'nyumba."

Pofuna kuonetsetsa kuti zinthu zomwe zimakhudzidwa ndi kutentha ndi chinyezi zikugwiritsidwa ntchito moyenera pokonza zinthu, komanso kuti zinthu zomwe zimakhudzidwa ndi kutentha ndi chinyezi zisamakhudzidwe ndi chinyezi m'chilengedwe, zinthu zomangira zinthu zosagwirizana ndi kutentha zimagwiritsidwa ntchito. Mfundo zotsatirazi zitha kusamalidwa bwino komanso kulamulidwa kuti zipewe kukhudzidwa ndi zinthu chifukwa cha kasamalidwe kosayenera komanso khalidwe lolamulira.

Malamulo Okhudza Zachilengedwe

Kutentha kwa malo ogwirira ntchito komwe zinthu zomwe zimakhudzidwa ndi kutentha ndi chinyezi zimagwiritsidwa ntchito ndi 18~28℃, ndipo chinyezi chimakhala pakati pa 40%~60%; Posunga, chinyezi cha bokosi losakhudzidwa ndi chinyezi chimakhala chochepera 10%, ndipo kutentha kumakhala pakati pa 18~28℃； Ogwira ntchito yosungiramo zinthu amawunika kutentha ndi chinyezi cha bokosi losakhudzidwa ndi chinyezi maola 4 aliwonse, ndikulembetsa kutentha ndi chinyezi chake patebulo lowongolera kutentha ndi chinyezi; ngati kutentha ndi chinyezi zipitirira malire omwe atchulidwa, nthawi yomweyo dziwitsani ogwira ntchito oyenerera kuti akonze, ndikuchita njira zoyenera zothanirana ndi vutoli, monga chowumitsira, kusintha kutentha kwa mkati, kapena kuchotsa zinthuzo m'bokosi losakhudzidwa ndi chinyezi ndikuziyika m'bokosi loyenerera losakhudzidwa ndi chinyezi. Nthawi yotsegulira kapena nthawi yotsegulira malo otetezedwa ndi kutentha ndi chinyezi m'dera lililonse lotsekedwa siyenera kupitirira mphindi 5 kuti muwonetsetse kuti kutentha ndi chinyezi zikupitirirabe mkati mwa malire olamulidwa.

Kuwongolera njira

a. Mukachotsa phukusi la vacuum la zigawo zomwe zimakhudzidwa ndi chinyezi mu inverterpompu yamadziNgati mukufuna kupanga chigamba cha bolodi lolamulira, muyenera kuvala lamba wamanja wa electrostatic ndi magolovesi a electrostatic, ndikutsegula phukusi la vacuum patebulo lomwe lili ndi chitetezo chabwino cha electrostatic. Mukachotsa, onetsetsani ngati kusintha kwa khadi la chinyezi kukukwaniritsa zofunikira (malinga ndi zofunikira pa chizindikiro pa thumba lolongedza). Pa ma circuits ophatikizidwa a SMD omwe akukwaniritsa zofunikira, chizindikiro chowongolera cha zigawo zomwe zimakhudzidwa ndi chinyezi chiyenera kumangiriridwa pa phukusi.

b. Pamene mzere wopanga umalandira zinthu zomwe zimakhudzidwa ndi chinyezi chochuluka, ndikofunikira kutsimikizira ngati zinthuzo zili zoyenerera malinga ndi chizindikiro cholamulira zinthu zomwe zimakhudzidwa ndi chinyezi, ndipo zinthu zomwe zimayenerera ziyenera kugwiritsidwa ntchito moyenera.

c. Pambuyo poti chinthu chokhudzidwa ndi chinyezi chatulutsidwa, nthawi yomwe chiyenera kuyikidwa mumlengalenga musanatulutsenso madzi siyenera kupitirira mulingo ndi moyo wa chinthu chokhudzidwa ndi chinyezi.

d. Pa ma circuits ophatikizidwa omwe amafunika kuphikidwa ndi osayenerera, adzaperekedwa kwa ogwira ntchito yoyang'anira khalidwe kuti akane ndikubwezedwa ku nyumba yosungiramo katundu.

njira yowongolera

Mu mayeso athu apadera a kafukufuku ndi chitukuko cha labu, tinayang'ana makamaka kusakhazikika kwa magetsi. Deta yathu ikuwonetsa kutipamene magetsi olowera akusintha ndi kupitirira ± 15%, dongosolo lowongolera limayambitsa njira yosinthira ndalama, kusinthaNthawi yoyankhira ya PID algorithm mkati mwa 100ms - 150msKusintha kumeneku kwa millisecond kumaletsa bwino kugwedezeka kwa torque, kuonetsetsa kuti pampu yolowa m'madzi imasunga mphamvu yotulutsa mphamvu nthawi zonse ngakhale mphamvu ikapanda kukhazikika.

a. Kuyang'ana zinthu zomwe zikubwera—thumba la desiccant ndi khadi losonyeza chinyezi ziyenera kumangiriridwa ku thumba losanyowa, ndipo zizindikiro zoyenera ziyenera kumangiriridwa kunja kwa thumba losanyowa. Ngati phukusi silili bwino, liyenera kutsimikiziridwa ndi ogwira ntchito oyenerera.

b. Kusunga zinthu—zinthu zosatsegulidwa ziyenera kusungidwa motsatira malangizo; ngati zinthu zosatsegulidwa ziyenera kubwezeretsedwa ku nyumba yosungiramo zinthu kuti zisungidwe, ziyenera kutsekedwa mu thumba losanyowa mutaphika; ngati zinthu zosatsegulidwa sizigwiritsidwa ntchito nthawi yomweyo, ziyenera kusungidwa kwakanthawi mu uvuni wotentha pang'ono.

c. Kugwiritsa ntchito pa intaneti - tsegulani zinthuzo mukazigwiritsa ntchito, ndipo yang'anani ndikudzaza khadi lowonetsa chinyezi nthawi yomweyo; lembani khadi lowongolera mafuta ndikuwonetsa chizindikiro cha zinthu zomwe zimakhudzidwa ndi kutentha ndi chinyezi mukasintha zinthu; bwezerani zinthuzo motsatira malamulo osungiramo zinthu kenako muzizinyamula ndikuzisunga motsatira zofunikira zomwe zikugwirizana nazo mutachotsa zinthuzo.

D. Kuchotsa chinyezi m'nthaka - sankhani nthawi yophikira ndi momwe zinthuzo zimagwiritsidwira ntchito malinga ndi kuchuluka kwa chinyezi cha zigawo za SMD, momwe zinthu zilili, komanso nthawi yotsegulira.

Zomwe zili pamwambapa ndi njira yoyendetsera pampu yonyowa ya DC variable frequency submersible. Ngati mukufuna kudziwa zambiri za pampu yamadzi yaying'ono, chonde titumizireni uthenga.

Kudzipereka Kudalirika:"Ku Pinmotor, mfundo zathu zowongolera ma frequency osiyanasiyana a DC sizimangokonzedwa kuti zigwire bwino ntchito komanso zimayesedwa mwamphamvu kuti zigwirizane ndi zomwe zanenedwa."IEC 60034(Makina Amagetsi Ozungulira) ndiMalangizo a EMC 2014/30/EU. Mwa kutsatira miyezo yapadziko lonse lapansi iyi, tikutsimikizira kuti makina athu owongolera mapampu amapereka kukhazikika kwa nthawi yayitali komanso kugwirizana kwa ma elekitiromagineti m'malo osiyanasiyana ogwirira ntchito.
