Vavu yofananira yamagetsi-yotchedwa valavu yofananira.Makhalidwe ake ndikuti kuchuluka kwa zotulutsa kumasintha ndi kuchuluka kwa zolowetsa.Pali ubale wina wofananira pakati pa zotulutsa ndi zolowetsa, motero amatchedwa valavu yamagetsi yamagetsi.

Valavu yofananira imapangidwa ndi chosinthira ma electro-mechanical ndi pneumatic amplifier, ndipo ndi njira yotseka-loop control system.Dongosolo limazindikira mosalekeza zotuluka (kukakamiza) kumapeto kwa zotulutsa ndikuzibwezeranso kumapeto kwa dongosolo kuti zifananize ndi zomwe zalowetsedwa (ziyenera kufunikira).Pamene mtengo weniweni wa kutulutsa (kupanikizika kwamtengo wapatali) umachoka pamtengo (mtengo woyembekezeredwa), dongosololi limakonza zotulukapo kuti zisinthe njira yomwe ili pafupi ndi zomwe zimalowetsamo, kuti zitsimikizire kuti zotulukazo zimakhala zokhazikika mkati mwa mtengo wokakamiza wofunikira. mwa kulowa.Sungani mgwirizano wolingana pakati pa zotulutsa ndi zolowetsa.

Mawonekedwe:

Mphamvu yotulutsa imasintha ndi chizindikiro cholowera, ndipo pali zofananira

mgwirizano pakati pa mphamvu yotulutsa ndi chizindikiro cholowetsa.

Ndi stepless voltage regulation mphamvu.

Ndi kuthekera kwa kuwongolera kwakutali ndi kuwongolera pulogalamu: mtengo wokwanira wa valavu yofananira umayikidwa ndi kulumikizana, kutumiza kwa chizindikiro chakutali kumakhala kokhazikika, ndipo mtunda wowongolera ukhoza kukulitsidwanso.Itha kuzindikirika ndi PC, single chip microcomputer, PLC ndi zida zina.

Zindikirani:

1. Pamaso pa valavu yamagetsi yamagetsi, fyuluta ya mpweya ndi cholekanitsa nkhungu ya mafuta ndi kulondola kwa kusefera kwa 5μm kapena kuchepera.Perekani mpweya woyera ndi wowuma woponderezedwa ku valavu yofanana kuti mukwaniritse makhalidwe osiyanasiyana a valve yamagetsi yamagetsi.

2. Musanakhazikitse, mapaipi ayenera kutsukidwa.

3. Palibe mafuta omwe amayenera kuikidwa kumapeto kwa valve yofanana.

4. Valavu yofananira imadula mphamvu yamagetsi mumkhalidwe wopanikizika, ndipo kupanikizika kumbali yotuluka kumatha kusungidwa kwakanthawi, zomwe sizikutsimikiziridwa.Ngati mukufuna kutulutsa mpweya, zimitsani mphamvuyo mukatsitsa kupanikizika, ndipo gwiritsani ntchito valavu yotsalira kuti mutulutse.

5. Mu kayendetsedwe ka kayendetsedwe ka valve yofanana, kupanikizika kumbali yotuluka kumatha kusungidwa kamodzi chifukwa cha kulephera kwa mphamvu kapena kutaya mphamvu kwina.Kuonjezera apo, pamene mbali yotulukira itsegulidwa kumlengalenga, mphamvuyo idzapitirira kutsika ku mphamvu ya mumlengalenga.

Pambuyo pa valavu yofanana ndi mphamvu, ngati mphamvu yowonjezera ikutha, valavu ya solenoid idzagwirabe ntchito, yomwe idzatulutsa phokoso ndikuchepetsa moyo wake.Choncho, magetsi ayenera kudulidwa pamene gwero la gasi likudulidwa, mwinamwake valavu yofanana idzalowa "m'tulo".

6. Ma valve ofananira asinthidwa asanachoke ku fakitale, chonde musamasule kuti musagwire ntchito bwino.

7. Pamene valavu yofananira sichigwiritsa ntchito zotsatira zowunikira (kusintha kwa kusintha), waya wowunikira (waya wakuda) sangathe kukhudzana ndi mawaya ena kuti asagwire ntchito.Kugwiritsa ntchito ma inductive load (mavavu a solenoid, ma relay, ndi zina zotero) kuyenera kukhala ndi njira zoyamwitsa kwambiri.

8. Pewani kulephera kugwira ntchito chifukwa cha phokoso lamagetsi.Chogulitsa ichi ndi mawaya ake ayenera kukhala kutali ndi injini ndi chingwe chamagetsi kuti asatengeke ndi phokoso la mfundo.

9. Pamene mbali yotulutsa imakhala ndi voliyumu yayikulu ndipo ntchito yowonjezereka ikugwiritsidwa ntchito monga cholinga, phokoso lotulutsa mpweya limakhala lalikulu panthawi ya kusefukira, ndipo doko lotulutsa mpweya liyenera kukhala ndi silencer.

10. Pamene mtengo woyembekezeredwa uli wochepera 0.1V, umatengedwa ngati 0V.Izi zikachitika, kukakamiza kotulutsa kumayikidwa ku 0 Bar poyambitsa valavu yotulutsa mpweya ndipo mpweya womwe uli m'chipinda chofananirako watha.

11. Musanadule mphamvu ya valve yofanana, chonde onetsetsani kuti mudula mphamvu yamagetsi (yosakwana 0.1V), ndiyeno mudule mphamvu ya gwero la mpweya, ndipo potsirizira pake mudule mphamvu ya valavu yofanana.

12. Zofunikira za gwero la gasi: kukakamiza kolowera kuyenera kukhala kokulirapo kuposa kutulutsa kwamphamvu kuposa 0.1MP, ndikukwaniritsa kugwiritsa ntchito mpweya wonse, ndiko kuti, kutulutsa kwake kumakhala kwakukulu kuposa kutulutsa.
