Mitundu ndi kusankha kwa zowonjezera za valavu ya pneumatic

Mu ndondomeko yogwiritsira ntchitoValavu ya Pneumatic, nthawi zambiri pamafunika kukonza zinthu zina zothandizira kuti valavu yopyola mpweya igwire bwino ntchito, kapena kukonza bwino momwe valavu yopyola mpweya imagwirira ntchito. Zowonjezera zomwe zimagwiritsidwa ntchito pa valavu yopyola mpweya zimaphatikizapo: zosefera mpweya, mavalavu obwezeretsa mpweya, ma switch oletsa, malo oimika magetsi, ndi zina zotero. Mu ukadaulo wa pneumatic, zinthu zitatu zokonzera mpweya zomwe zili mu fyuluta ya mpweya, valavu yochepetsera kupanikizika ndi mafuta zimasonkhanitsidwa pamodzi, zomwe zimatchedwa pneumatic triple piece. Zimagwiritsidwa ntchito kulowa mu gwero la mpweya kuti zitsuke ndikusefa chida chopyola mpweya ndikuchepetsa kupanikizika kwa chida kuti chipereke gwero la mpweya loyesedwa. Kupanikizika kuli kofanana ndi ntchito ya transformer yamagetsi mu dera.

Mitundu ya Zida za Pneumatic Valve:

Choyambitsa Pneumatic Chogwira Ntchito Kawiri:

Kulamulira kwa malo awiri potsegula ndi kutseka ma valavu. (Kugwira ntchito kawiri)

Choyambitsa masika chobwerera ndi masika:

Vavu imatseguka kapena kutseka yokha pamene dera la mpweya wa dera ladulidwa kapena lalephera kugwira ntchito. (Imagwira ntchito kamodzi kokha)

Valavu imodzi yoyendetsedwa ndi magetsi ya solenoid:

Vavu imatseguka kapena kutsekedwa mphamvu ikaperekedwa, ndipo imatseka kapena kutsegula valavu mphamvu ikatayika (pali mitundu yosaphulika).

Valavu ya solenoid yoyendetsedwa ndi magetsi iwiri:

Vavu imatsegulidwa pamene chogwirira chimodzi chapatsidwa mphamvu, ndipo chogwiriracho chimatsekedwa pamene chogwirira china chapatsidwa mphamvu. Chili ndi ntchito yokumbukira (mtundu wakale wotsimikizira ulipo).

Bokosi Losinthira Malire:

Kutumiza kwa chizindikiro cha malo osinthira a valavu mtunda wautali (chokhala ndi mtundu wosaphulika).

Choyimitsa Magetsi:

Sinthani ndikuwongolera kuyenda kwapakati kwa valavu malinga ndi kukula kwa chizindikiro chamagetsi (muyezo wa 4-20mA) (chokhala ndi mtundu wosaphulika).

Choyimitsa Ma Pneumatic:

Sinthani ndikuwongolera kuyenda kwapakati kwa valavu malinga ndi kukula kwa chizindikiro cha kuthamanga kwa mpweya (standard 0.02-0.1MPa).

Chosinthira magetsi:

Imasintha chizindikiro chamagetsi kukhala chizindikiro cha kuthamanga kwa mpweya. Imagwiritsidwa ntchito limodzi ndi choyimitsa mpweya (chokhala ndi mtundu woteteza kuphulika).

FRL (Fyuluta ya Mpweya, Valavu Yowongolera, Lubricator):

Fyuluta ya Mpweya (F): amagwiritsidwa ntchito kusefa zinyalala ndi chinyezi mumlengalenga wopanikizika kuti atsimikizire ukhondo wa makina opumira.

Valavu Yowongolera (R): imagwiritsidwa ntchito kuchepetsa mpweya wopanikizika kwambiri kufika pa kupanikizika kofunikira kuti zitsimikizire kuti zipangizo zopumira zikugwira ntchito bwino.

‌Chopaka mafuta (L): imagwiritsidwa ntchito poika mafuta okwanira mu makina opumira kuti achepetse kukangana ndikuwonjezera nthawi ya zidazo.

Zigawozi nthawi zambiri zimagwiritsidwa ntchito pamodzi, zotchedwa pneumatic triplex (FRL), zomwe zimagwira ntchito yoyeretsa, kusefa komanso kuchepetsa kuthamanga kwa mpweya muukadaulo wa pneumatic.

Njira Yogwiritsira Ntchito Pamanja:

Kuwongolera kodziyimira pawokha kumatha kugwiritsidwa ntchito pamanja pazifukwa zachilendo.

Kusankha Zida za Pneumatic Valve

Valavu ya Pneumatic ndi chida chowongolera chokha chomwe chimagwira ntchito movutikira. Chimapangidwa ndi zinthu zosiyanasiyana zopumira. Ogwiritsa ntchito ayenera kusankha mwatsatanetsatane malinga ndi zosowa zawo zowongolera.

1. Choyendetsa pneumatic:

Mtundu wochita zinthu ziwiri
Mtundu wa sewero limodzi
Mafotokozedwe a chitsanzo
Nthawi yochitapo kanthu

2. Valavu ya Solenoid:

Valavu imodzi yolamulira ya solenoid
Valavu ya solenoid yolamulira kawiri
Mphamvu yogwiritsira ntchito
Mtundu wosaphulika

Kuyankha kwa Zizindikiro:

Chosinthira cha makina
Chosinthira chapafupi
Chizindikiro chamakono chotulutsa
Kugwiritsa ntchito magetsi
Mtundu wosaphulika

4. Choyimira:

Choyimitsa magetsi
Choyimitsa mpweya
Chizindikiro chamakono
Chizindikiro cha kuthamanga kwa mpweya
Chosinthira magetsi
Mtundu wosaphulika

5. Zigawo Zitatu za FRL:

Sefani
Valavu yochepetsera kupanikizika
Chipangizo chopaka utoto

6. Njira yogwiritsira ntchito ndi manja.
