Lamulo ndi mfundo za valavu yamagetsi yamagetsi yamagetsi yotumiza katundu kumawonjezeka chaka ndi chaka

Vavu yamagetsi imagwiritsidwa ntchito makamaka pakuwongolera kuchuluka kwa madzi ndi nthunzi tsiku lililonse la pulogalamu yamapaipi amagetsi. Mapangidwe a valve yamagetsi amatha kugawidwa m'magawo awiri, theka lapamwamba limagawidwa kukhala magetsi, theka lapansi limagawidwa mu valve.
Kugwira ntchito kwenikweni kwa magetsi oyendetsa magetsi kuti azitha kulamulira kayendedwe ka valve, kumaliza kutsegula ndi kutseka kwa valve, ndiyeno zindikirani zomwe zili mu chitoliro chosinthira mphamvu kapena kusintha. Makina oyendetsa magetsi a valve yamagetsi nthawi zambiri amakhala ndi magawo atatu asynchronous motor, transmission gear reducer, mtunda wochepetsera mtunda, mtundu wamanja ndi bungwe losintha zokha, chizindikiro chotsegulira ndi zida zamagetsi. Vavu galimoto linanena bungwe mphamvu zambiri 0.37 ~ 5.5kW.
Pofuna kuonetsetsa kuti mphamvu yodalirika yosinthira valve yamagetsi, chitetezo cha over-voltage chimayendetsedwa bwino. Njira zodzitetezera zodziwika bwino ndi mtundu wa zida zamagetsi ndi mtundu wa pedal. DL mtundu wa relay panopa amagwiritsidwa ntchito ngati overvoltage chitetezo kukonza zida zamagetsi. Kukonza ma pedal kumagwiritsa ntchito malire a giya pachitetezo chopitilira - voltage.
1. Malamulo owongolera
Lamulo la valve yamagetsi ndi: kanikizani batani lotseguka la valve, valavu imatsegulidwa, dinani batani lotseka, valavu yatsekedwa. Vavu ikatsegulidwa kapena kutsekedwa kwathunthu, bungwe lowongolera sitiroko limangotulutsa gawo lowongolera la ac contactor, ndikupeza valavuyo ndi yotseguka kapena yotseka chizindikiro chowunikira. DL mtundu waposachedwa wa relay umagwiritsidwa ntchito pokonza pomwe magetsi atsekedwa ndikulemedwa ndikutsegula kapena kutseka. Pali cholumikizira magetsi pakati lotseguka valavu ac contactor ndi pafupi valavu contactor.
Palinso njira yoyendetsedwa ndi pedal yokhala ndi kukonza ma overtorque pawiri komanso zida zowunikira ma valve.
2. Mfundo ya
Lumikizani magetsi osinthira, kuwala kwa chizindikiro kumayaka.
Gwirani makiyi a valve, ma electromagnetic contactor coil plug, ac contactor anatseka mfundo yaikulu yolumikizirana, ndipo galimoto imatembenuzidwa, valavu imatsegulidwa, panthawi imodzimodziyo ndi pulagi yoyendetsa nthawi, pulasitiki yaying'ono yotsekedwa nthawi zambiri imatsekedwa, ndi kutseka. relay yapano yomwe nthawi zambiri imatsekedwa, pewani kuthamanga kwambiri kwamagetsi kuti mutseke zolakwika zomwe zikuchitika. Nthawi yochedwa ya wowongolera nthawi ikafika, malo ochezera ochedwetsa amasweka, ndipo mphamvu yamagetsi yaying'ono imazimitsidwa. The kutseka kwenikweni anayambitsa ndi zambiri lotseguka ndipo kawirikawiri kutsekedwa kwa locking panopa relay ndi kawirikawiri chatsekedwa mfundo ya AC contactor. Vavu ikatsegulidwa kwathunthu, kanikizani chosinthira choyenda, cholumikizira cha AC chimazimitsa mphamvu, mota imatembenuka kuti iime, ndipo nthawi yomweyo valavu imatsegulidwa kwathunthu ndipo kuwala kumayaka.
Dinani batani kuti mutseke valavu, koyilo ya solenoid ya AC contactor imalumikizidwa, malo olumikizirana nawo a AC amatsekedwa, mota imatembenuka, ndipo valavu imatsekedwa. Ma relay ang'onoang'ono ndi maulendo a nthawi amagwira ntchito ndi valve yotsegulira. Vavu ikatsekedwa, kanikizani chosinthira choyenda, cholumikizira cha AC chimazimitsa mphamvu, mota imazimitsa, ndipo nthawi yomweyo valavu imatsekedwa, kuwala kowonetsera kumayatsidwa. Onani zotsatirazi mukamagwiritsa ntchito chowongolera nthawi: Kuchedwa kwa nthawi kwa wowongolera nthawi kumakhala 3 mpaka 5S. Ngati palibe chowongolera nthawi chomwe chakonzedwa, onjezani nthawi yakukanikiza batani.
Chiŵerengero cha katundu wotumizidwa kunja chimawonjezeka chaka ndi chaka
Vavu zofunika wakhala m'malo mayiko, kwa chilengedwe, kuvulaza kwake ndi kwakukulu kwambiri, munda wa valavu wa China uyenera kukhala wodekha, kupititsa patsogolo luso lawo lotumizira ndi kutumiza kunja kwa malonda okhudzana ndi malonda, makamaka zofunikira zochepa zamakono za mankhwala apakati ambiri a valve, omwe amachitira ambiri. kampani, mankhwala homogeneity ndizovuta kwambiri, kuchulukitsa, kuchepa kwa phindu, Makampani ambiri a valve akhala akuchokera pakukula kwa katundu wa kunja kuti apulumuke, kuchuluka kwa katundu wa vavu ndi kukula pang'onopang'ono.
Kuyambira Januwale mpaka June mu 2013, Wenzhou, malo ofunikira kupanga valavu ku China, adatumiza magulu 8109 a zinthu za valve, ndikukula kwa chaka ndi chaka cha 0.61%, komanso kutumiza kunja kwa madola 260 miliyoni a US, chaka ndi chaka. -chaka kuchepa kwa 2.98%, kutsika mosalekeza, ndipo mu 2012, 1-6 Wenzhou vavu katundu wogulitsa chinawonjezeka kufika 42%, deta deta kusiyana ndi lalikulu, Tingaone kuti zofunika valavu ndi zoipa kwambiri kwa chilengedwe cha chuma padziko lonse. .
Kukulitsa zogulitsa kunja si vuto linalake processing valavu makampani chitukuko vuto, komanso zovuta kupewa mavuto mwa kuyang'ana otsogola katundu deta zambiri kusonyeza pang'onopang'ono: ambiri valavu katundu kunja kwa kukulitsa lokha katundu msika gawo, ku China msika mtengo mpikisano countermeasure, njiru mtengo mpikisano. akupitiriza kuwonjezeka. Makampani ambiri ang'onoang'ono ndi apakatikati akupikisana pamitengo kuti apeze zambiri zamadongosolo apadziko lonse lapansi. Komabe, mabizinesi ang'onoang'ono ndi apakatikati pamtengo wotsika wazinthu kuti apeze maoda akunja, kuti athe kuwongolera bwino mtengo, nthawi zambiri amakhala opanda pake. Zotsatira zake, zinthu zomalizidwa sizili oyenerera ndipo kudalirika kwa ma valve aku China akuyika pachiwopsezo. ** Zowopsa ndizakuti pakapita nthawi, makampani opanga ma valve aku China atha kuvutitsidwanso ndi chitetezo pamsika wapadziko lonse lapansi.
Pakadali pano, ma valve otumiza kunja nthawi zambiri amachotsedwa mu DOLLAR, ndipo chiwopsezo cha kusinthana komwe kumachitika chifukwa cha kuyamikira kwa RENMINBI ndikuwonjezeranso mafuta pamoto. Opanga mavalavu ena alibe zinthu zolimba, zabodza komanso zopanda pake, zimawononga ndalama zamabizinesi omwewo ku China komanso chithunzi chazinthu zaku China zotulutsira valavu. Tsoka ilo, zomwe zidapangitsa kuti gawo la ma valve otumiza kunja lipitirire kuchepa.
Mu 2013, makampani Chinese vavu anakumana kukakamiza katundu kukulitsa zinthu, makampani valavu ayenera kulimbikitsa luso luso, kuchokera kuganizira chiwerengero okwana, kukula kwa sikelo bizinesi kulabadira kwambiri kufunafuna khalidwe wangwiro, phindu lachuma, ndi mwakhama kukhala. Msika wogulitsa waku China, umalimbikitsa chitukuko choyenera cha gawo la valve yaku China. Ndipo malinga ndi zofunikira zaukadaulo zamakampani ena ang'onoang'ono ndi apakatikati a valve, amatha kuganizira zamakampani atsopano agawidwe, monga kufunika kwa valavu yamadzi olekanitsa, kupititsa patsogolo ntchito zama projekiti zothandizira, kukulitsa mtengo wowonjezera wa valve.
Kubwezeretsa kwachuma padziko lonse lapansi kuyenera kukhala pang'onopang'ono, valavu yofunikira ndi chilengedwe chachuma padziko lonse lapansi ndi yayikulu, gawo la valavu la China liyenera kuyankha modekha kuti lizitha kuyankhulana ndi kuopsa kwa malonda ogulitsa kunja ndi kunja, pakukulitsa malonda pa nthawi yomweyo. , Komanso sangathe kumasula kukakamizidwa pa chitukuko cha malonda msika China. Cholinga cha kampaniyo chikhoza kupititsa patsogolo makina opanga mafakitale, kupita ku makampani apamwamba a valve kuti apite patsogolo, monga mafuta opangira mafuta, magetsi a nyukiliya ndi mafakitale ena amtundu wachitukuko, mavavu otumizidwa kunja kukula kwa msika sikungathe kunyalanyazidwa.
