Mitundu ndi kusankha kwa zida zamagetsi zamagetsi

Mukamagwiritsa ntchito valavu yampweya, nthawi zambiri kumakhala kofunikira kukonza zida zina zothandizira kukonza magwiridwe antchito a pneumatic valve, kapena kukonza magwiridwe antchito a pneumatic valve. Zowonjezera zama pneumatic valves zimaphatikizapo: zosefera mpweya, zotsekereza ma solenoid, ma switch osinthira, zida zamagetsi, ndi zina. Muukadaulo wa pneumatic, zinthu zitatu zopangira mpweya wa fyuluta ya mpweya, kukakamiza kuchepetsa valavu ndi abambo amafuta zimasonkhanitsidwa palimodzi, zomwe zimatchedwa a pneumatic chidutswa chachitatu. Amagwiritsidwa ntchito polowetsa mpweya kuti ayeretse ndi kusefa chida chamagetsi ndikuchepetsa kukakamizidwa kwa chida kuti chiperekereko mpweya Wopanikizika ndikofanana ndi ntchito yamagetsi yamagetsi yoyenda.

API602 Globe Valve

Mitundu yamagetsi yama pneumatic:

Kuchita pneumatic actuator kawiri: Kuwongolera malo awiri kutsegulira ndi kutseka kwa valavu. (Kuchita kawiri)

Makina obwerera kumapeto kwa kasupe: Valavu imatsegulidwa kapena kutseka yokha pomwe dera lamagesi limadulidwa kapena latha. (Kuchita osakwatira)

Valavu yamagetsi yamagetsi yamagetsi osagwiritsidwa ntchito pakompyuta imodzi: Valavu imatseguka kapena kutseka mphamvu ikaperekedwa, ndikutseka kapena kutsegula valavu mphamvu ikatayika (mitundu yopezera kuphulika ikupezeka).

Valavu yamagetsi yamagetsi yoyendetsedwa kawiri pamagetsi: Valavu imatseguka pomwe coil imodzi imapatsidwa mphamvu, ndipo valavu imatsekedwa pomwe coil inayo ilimbikitsidwa. Ili ndi ntchito yokumbukira (mtundu wakale waumboni ulipo).

Malire osinthira echo: Kutumiza kwakutali kwa siginecha yamagetsi yosinthira (ndi mtundu wophulika).

Pogwiritsa ntchito magetsi: Sinthani ndikuwongolera mayendedwe apakati a valavu kutengera kukula kwa siginecha yapano (standard 4-20mA) (yokhala ndi mtundu wophulika).

Pneumatic positioner: Sinthani ndikuwongolera mayendedwe apakati a valavu kutengera kukula kwa chizindikiritso cha mpweya (standard 0.02-0.1MPa).

Wotembenuza zamagetsi: Amatembenuza siginecha wapano kukhala siginecha wamagetsi. Amagwiritsidwa ntchito limodzi ndi pneumatic positioner (yokhala ndi mtundu wophulika).

Kupanga magwero atatu am'mlengalenga: kuphatikiza kuthamanga kwa mpweya kochepetsera valavu, fyuluta, chida cha nkhungu yamafuta, kukhazikika pamagetsi, kuyeretsa ndi mafuta amafuta oyenda.

Buku limagwirira ntchito: Kuwongolera kwazokha kumatha kugwiritsidwa ntchito pamanja pazinthu zachilendo.

Kusankhidwa kwa zida zamagetsi zamagetsi:

Pneumatic valve ndi chida chodziwikiratu chowongolera. Amapangidwa ndi zida zosiyanasiyana za pneumatic. Ogwiritsa ntchito amafunika kusankha mwatsatanetsatane malingana ndi zosowa zawo.

1. Pneumatic actuator: ① mitundu iwiri yochita, acting mtundu wothandizira, ③ mafotokozedwe achitsanzo, nthawi yothandizira.

2. Solenoid valavu: ① single control solenoid valve, ② control control solenoid valve, ③ voltage yogwiritsira ntchito, type mtundu wophulika

3. Chizindikiro chazidziwitso: switch makina osinthira, switch kuyandikira, signal kutulutsa mbendera, voltage kugwiritsa ntchito magetsi, type mtundu wosaphulika

4. Positioner: position magetsi, pneumatic positioner, signal mbendera yapano, signal kuthamanga kwa mpweya, converter chosinthira magetsi, type mtundu wosaphulika.

5. Katatu mbali mankhwala gwero: ① fyuluta kuthamanga kuchepetsa valavu, device chipangizo mafuta nkhungu.

6. Buku limagwirira ntchito.
