Chowonjezera chachikulu cha actuator ya pneumatic ndivalavu yowongoleraChoyimira. Chimagwira ntchito limodzi ndi chowongolera mpweya kuti chiwonjezere mphamvu yakulondola kwa malo a valavu, kuchepetsa mphamvu yosalinganika ya chinthucho ndi kukangana kwa tsinde, ndikuwonetsetsa kuti valavu ikuyankha chizindikiro cha wowongolera. Pezani malo oyenera.

Zinthu zotsatirazi zimafuna kugwiritsa ntchito malo opezera malo:
Ngati kuthamanga kwapakati kuli kokwera ndipo pali kusiyana kwakukulu kwa kuthamanga; 2. Ngati mphamvu ya valavu yowongolera ili yayikulu (DN> 100);
3. Valavu yowongolera kutentha kwambiri kapena kotsika;
4. Pamene kuli kofunikira kufulumizitsa ntchito ya valavu yowongolera;
5. Pamene zizindikiro zokhazikika zimagwiritsidwa ntchito kuyendetsa ma actuator okhala ndi ma spring range osazolowereka (ma spring ranges kunja kwa 20-100KPa);
6. Nthawi iliyonse pamene kulamulira kwa ma split-range kukugwiritsidwa ntchito;
7. Pamene valavu yatembenuzidwa, njira zotsekera mpweya ndi kutsegula mpweya zimakhala zosinthika;
8. Pamene kamera yoyimilira ikufunika kusinthidwa kuti isinthe mawonekedwe a valavu;
9. Ngati ntchito yofanana ikuchitika, palibe choyezera pistoni kapena njira yogwiritsira ntchito masika;
10. Ma valve positioners amagetsi ndi pneumatic ayenera kugawidwa pogwiritsa ntchito zizindikiro zamagetsi kuti azilamulira ma actuator a pneumatic.

Valavu yamagetsi: Valavu ya solenoid iyenera kuyikidwa mu dongosolo pamene pulogalamu yowongolera kapena yowongolera malo awiri ikufunika. Kugwirizana pakati pa valavu ya solenoid ndi valavu yowongolera kuyenera kuganiziridwa posankha valavu ya solenoid kuwonjezera pa gwero lamphamvu la AC ndi DC, voltage, ndi ma frequency. Ikhoza kukhala ndi magwiridwe antchito "otseguka nthawi zambiri" kapena "otsekedwa nthawi zambiri".
Ma valve awiri a solenoid angagwiritsidwe ntchito nthawi imodzi ngati pakufunika kuwonjezera mphamvu ya solenoid valve kuti muchepetse nthawi yogwira ntchito, kapena solenoid valve ingagwiritsidwe ntchito ngati valavu yoyendetsera ntchito limodzi ndi pneumatic relay yayikulu.

Kutumiza kwa mpweya (pneumatic relay): Kutumiza kwa mpweya (pneumatic relay) ndi mtundu wa amplifier yamphamvu yomwe ingapereke chizindikiro cha mpweya kupita kutali kuti ichotse kuchedwa komwe kumachitika chifukwa cha kufalikira kwa mapaipi a chizindikiro. Pakati pa chowongolera ndi valavu yowongolera mpweya (field regulatory valve), pali ntchito yowonjezera yowonjezera kapena kuchepetsa kukula kwa chizindikirocho. Chimagwiritsidwa ntchito makamaka pakati pa chotumizira mpweya (field transmitter) ndi chipangizo chowongolera chomwe chili m'chipinda chowongolera chapakati.

chosinthira:
Chosinthira chimagawidwa m'magulu awiri: chosinthira magetsi ndi gasi ndi chosinthira magetsi ndi gasi. Ntchito yake ndikukwaniritsa kusinthana kwa ubale wina pakati pa zizindikiro za gasi ndi zamagetsi. Chimagwiritsidwa ntchito makamaka kusintha chizindikiro chamagetsi cha 0 ~ 10mA kapena 4 ~ 20mA kapena chizindikiro cha mpweya cha 0 ~ 100KPa kukhala chizindikiro chamagetsi cha 0 ~ 10mA kapena 4 ~ 20mA.

chowongolera cha zosefera mpweya:

Cholumikizira cha chipangizo chomwe chimagwiritsidwa ntchito ndi zida zodzipangira zokha zamafakitale ndi valavu yochepetsera kuthamanga kwa mpweya. Ntchito yake yayikulu ndikukhazikitsa kupanikizika pamlingo womwe ukufunidwa posefa ndikuyeretsa mpweya wopanikizika wochokera ku compressor ya mpweya. Silinda ya mpweya, zida zopopera, magwero a mpweya, ndi zida zolimbitsa kuthamanga kwa mpweya za zida zazing'ono zopumira ndi zitsanzo za zida zopumira ndi mavalavu a solenoid omwe angagwiritsidwe ntchito.

Valavu yotetezera (valavu yodzitsekera yokha)

Valavu yodzitsekera yokha ndi njira yomwe imasunga valavu pamalo ake. Pamene gwero la mpweya lalephera, chipangizocho chimatha kuzimitsa chizindikiro cha gwero la mpweya kuti chisunge chizindikiro cha kuthamanga kwa chipinda cha nembanemba kapena silinda pamalo ake asanalephereke komanso malo a valavu pamalo ake asanalephereke. Kuteteza malo.

chotumizira malo cha ma valve
Pamene valavu yowongolera ili kutali ndi chipinda chowongolera, ndikofunikira kuyika chotumizira malo a valavu, chomwe chimasintha kusamuka kwa valavu kukhala chizindikiro chamagetsi ndikuchitumiza ku chipinda chowongolera motsatira lamulo lokhazikitsidwa, kuti timvetsetse bwino malo osinthira a valavu popanda kupita pamalopo. Chizindikirocho chingakhale chizindikiro chopitilira chomwe chikuyimira kutsegula kulikonse kwa valavu kapena chingawonedwe ngati ntchito yobwezera kumbuyo kwa valavu.

Kusinthana kwa kulumikizana paulendo
Chosinthira malire ndi gawo lomwe limatumiza chizindikiro chosonyeza nthawi imodzi ndikuwonetsa malo awiri ofunikira a chosinthira cha valavu. Chipinda chowongolera chikhoza kunena momwe chosinthira cha valavu chilili kutengera chizindikirochi ndikuchitapo kanthu koyenera.
