Makina oyendetsera mpweya a pneumaticChowonjezera chachikulu ndi chowongolera valavu. Chimagwira ntchito limodzi ndi chowongolera mpweya kuti chiwonjezere kulondola kwa malo a valavu, kuchepetsa mphamvu yosalinganika ya chinthucho ndi kukangana kwa tsinde, ndikuwonetsetsa kuti valavuyo ikuyankha chizindikiro cha chowongolera.

Zinthu zotsatirazi zimafuna kugwiritsa ntchito malo opezera malo:

1. Pakakhala kusiyana kwakukulu kwa kuthamanga kwa magazi ndi kuthamanga kwa magazi kwapakati;

2. Pamene kukula kwa valavu yowongolera kuli kwakukulu (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 pakufunika kuchitapo kanthu molingana, sipafunika choyezera masika kapena pistoni;

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 pneumatic:
Cholumikizira cha pneumatic ndi mtundu wa amplifier yamphamvu yomwe imatha kutumiza chizindikiro cha mpweya kutali kuti ichepetse nthawi yochedwa yomwe imabwera chifukwa cha kutambasula mapaipi a chizindikiro. Pakati pa chowongolera ndi valavu yowongolera malo, pali ntchito yowonjezera yowonjezera kapena kuchepetsa kukula kwa chizindikiro. Chimagwiritsidwa ntchito makamaka pakati pa chotumizira malo ndi chipangizo chowongolera m'chipinda chowongolera chapakati.

chosinthira:
Pali mitundu iwiri ya ma converter: chosinthira magetsi ndi gasi ndi magetsi. Kuzindikira kusintha kofanana kwa ubale weniweni pakati pa ma signali a gasi ndi magetsi ndi komwe kumagwira ntchito. Chimagwiritsidwa ntchito kwambiri posintha ma signali a gasi a 0 100KPa kukhala ma signali amagetsi a 0 10 mA kapena 0 4 mA, kapena ma signali amagetsi a 0 10 mA kapena 4 mA kukhala ma signali amagetsi a 0 10 mA kapena 4 mA.

Chowongolera fyuluta ya 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.

Vavu yodzitsekera yokha (valavu yotetezera):
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.

chopatsira malo a valavu
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 maulendo (kolumikizirana)
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.
