Zida zamagetsi zowongolera pneumatic

Locator

The zigawo zikuluzikulu za actuator pneumatic ayenera chikufanana ndi actuator pamene ntchito. Ikhoza kukonza kulondola kwa valavu ndikuchepetsa mphamvu yakuthyola kwa tsinde la valavu ndi mphamvu yosasunthika ya sing'anga, kuti zitsimikizire kuyika kolondola kwa valavu molingana ndi chizindikiro choperekedwa ndi woyang'anira. Pansi pazifukwa ziti muyenera kukhazikitsa malo okhala ndi pneumatic valve control valve:

1. Pamene kupanikizika kwapakati kumakhala kwakukulu ndipo kusiyana kwapanikizika kumakhala kwakukulu;

2. Pamene mawonekedwe a valavu yoyang'anira amakhala akulu kwambiri (DN> 100);

3. Kutentha kwakukulu kapena valavu yotsika kutentha;

4. Ndikofunika kuonjezera liwiro logwirira ntchito la valavu yoyang'anira;

5. Pakakhala kuwongolera koyenera;

6. Pakakhala chizolowezi chazizindikiro kuti mugwiritse ntchito chopanga chosakhazikika cha kasupe (kasupeyu amakhala kunja kwa 20 ～ 100KPa);

7. Pozindikira kusinthanso kwa valavu (mtundu wotsekera mpweya ndi mtundu wotseguka umasinthasintha);

8. Makhalidwe oyendera a valavu akuyenera kusinthidwa (choikapo cam chingasinthidwe);

9. Pakakhala kuti palibe kasupe woyendetsa kapena pisitoni woyendetsa, ndikofunikira kukwaniritsa zochita zake;

10. Mukamagwiritsa ntchito zikwangwani zamagetsi kugwiritsa ntchito zida zampweya, mphamvu iyenera kugawidwa kwa wopumira pneumatic valve.

Valavu yamagetsi yamagetsi
Pamene dongosololi liyenera kukwaniritsa kuwongolera pulogalamu kapena kuwongolera magawo awiri, liyenera kukhala ndi valavu yamagetsi. Mukamasankha valavu ya solenoid, kuphatikiza pamaganizidwe amagetsi a AC ndi DC, magetsi ndi pafupipafupi, chidwi chiyenera kulipidwa ku ubale wapakati pa valavu ya solenoid ndi valavu yoyang'anira. Nthawi zambiri kutseguka kapena kutsekedwa nthawi zambiri kumatha kugwiritsidwa ntchito.

Ngati mukufuna kuwonjezera mphamvu yamagetsi yamagetsi kuti mufupikitse nthawi yochitapo kanthu, mutha kugwiritsa ntchito mavavu awiri amtundu umodzi mofananira kapena kugwiritsa ntchito valavu ya solenoid ngati valavu yoyendetsa mothandizana ndi kulandirana kwakukulu kwa pneumatic.

Pneumatic kulandirana
Pneumatic kulandirana ndi mtundu wa mphamvu mkuzamawu, amene angatumize mpweya kuthamanga mbendera malo akutali, kuchotsa kwanthawi chifukwa cha kutalika kwa payipi mbendera. Amagwiritsidwa ntchito makamaka pakati pa chopatsilira chakumunda ndi chida chowongolera m'chipinda chowongolera chapakati, kapena pakati pa wolamulira ndi valavu yoyang'anira munda. Ntchito ina ndikulitsa kapena kuchepetsa chizindikirocho.

wotembenuza
Wosinthira wagawika mu chosinthira chamagesi-chamagetsi ndi chosinthira magetsi-gasi, ndipo ntchito yake ndikuzindikira kutembenuka kwa ubale wina pakati pamagetsi amagetsi ndi magetsi. Mukamagwiritsa ntchito zizindikiritso zamagetsi kuti mugwiritse ntchito ma pneumatic actuator, wotembenuza amatha kusintha ma siginecha amagetsi kukhala ma siginolo osiyana siyana.

Kutsekemera kwa mpweya kumachepetsa valavu
Mpweya wothira mpweya wochepetsera valavu ndizowonjezera pazida zamagetsi. Ntchito yake yayikulu ndikusefa ndikuyeretsa mpweya wopanikizika kuchokera ku kompresa wa mpweya ndikukhazikika pamavuto pamtengo wofunikira. Itha kugwiritsidwa ntchito pazida zosiyanasiyana zampweya ndi ma valve amagetsi. , Chida cha mpweya ndi zida zokhazikika zamagetsi zamagetsi, zida zopopera ndi zida zazing'ono za pneumatic.

Vuto lokhazikika (valavu yamalo)
Valavu yodziletsa yokha ndi chida chomwe chimasunga mawonekedwe a valavu. Pomwe mpweya umalephera, chipangizocho chimatha kudula chizindikiritso cha mpweya kuti chikwangwani cha chipinda kapena silinda chikhale chosavomerezeka m'boma nthawi yomweyo asanalephereke, chifukwa chake mawonekedwe a valavu amasamaliridwanso asanalephereke.

Vavu malo chopatsilira
Valavu yoyendetsera ikakhala kutali ndi chipinda chowongolera, kuti mumvetsetse bwino kusinthana kwa valavu popanda pamalopo, ndikofunikira kukonzekeretsa malo opumira. Chizindikirocho chimatha kukhala chizindikiritso chosalekeza chowonetsa kutseguka kulikonse kwa valavu, kapena chitha kuwonedwa ngati chosinthika cha choikapo valavu.

Kusintha kwaulendo (woyankha)
Kusinthana kwaulendo kumawonetsa malo awiri opitilira muyeso wa valavu ndikutumiza chizindikiritso nthawi yomweyo. Kutengera ndi chizindikiro ichi, chipinda chowongolera chitha kuzimitsa valavu kuti ichitepo kanthu mofanana.
