Magetsi a magetsi kumadzi: mitundu ndi kufotokozera

M'dziko lamakono, njira zodziyendetsera kayendetsedwe ka madzi zakhala mbali ya moyo wathu. Vesi yamagetsi (solenoid) ya madzi imagwiritsidwa ntchito kwambiri mu njira zosiyanasiyana zamapipi ndi zipangizo zodzilamulira. Chipangizocho sichigwiritsidwa ntchito pokhapokha muzinthu zovuta zamakono, komanso zapakhomo. Mothandizidwa ndi valve solenoid, mukhoza kutulutsa madzi okwanira nthawi inayake. Mwachitsanzo, njira zothirira zowonjezera madzi, kuyang'anira kayendedwe ka kutentha, kayendedwe ka malo otentha ndi madzi.

Chipangizo cha valve yamagetsi

Mavalo omwe amadziwika bwino, omwe chithunzi chake chikuwonetsedwa kumanzere, ali ndi zinthu zofunika kwambiri:

• Solenoid coil;
• Chophimba chinsalu;
• Chitsamba chotsekera;
• Pulogalamu ya valve valve;
• Chombo choyendetsa;
• Mfupa ya membrane amplifier;
• Mtsinje waukulu;
• Khomo loyenda bwino;
• Kutseguka kwa valve kukakamizidwa pogwiritsa ntchito kasupe.

Kodi magetsi opangira magetsi amadzi otani?

Magetsi a solenoid valves ndi omveka bwino:

• Thupi la valve ndi chivundikiro kawirikawiri zimapangidwa ndi mkuwa, mapuloteni apadera, chitsulo choponyedwa ndi chitsulo chosapanga dzimbiri, chifukwa chipangizocho chimagwira ntchito zosiyanasiyana, kutentha ndi zovuta;
• Monga maziko a kulumikiza, zimbudzi, mphira, silicone ndi fluoroplastic ndizoyenera;
• Mafupa ndi ndodo amapangidwa ndi maginito apadera;
• Mapulogalamu a magetsi a valve ali muzitseko zotsekedwa zomwe zimateteza chipangizo kuchokera ku fumbi;
• Pogwiritsa ntchito makompyuta, waya wopangidwa ndi magetsi amagwiritsidwa ntchito.

Mfundo yogwirira ntchito

Pa malo otsika, pamene chophimba cha chipangizochi chimasokonezeka, chifukwa cha chitsimikizo cha kasupe, piritsi kapena pistoni ya valve imakhala yogwirizana kwambiri ndi mpando wa valve. Motsogoleredwa ndi magetsi, magetsi otseguka amatsegula. Izi ndichifukwa chakuti maginito opangidwa mkati mwa chipangizocho amakoka plunger mu voil valve.

Ngati magetsi amatha kusokonekera, kapena kuti magetsi osakanikirana, magetsi opangira magetsi angagwiritsidwe ntchito ngati matepi ochiritsira . Kuti muchite izi, mutembenuzire valavuyo motsatira ndondomeko yomwe yawonetsedwa ndivi ndi 1/4 kutembenuka.

Mitundu ya valenoid valves

Vuto lotsekemera lakumadzi kwa madzi, malingana ndi kayendedwe ka kutembenuka ndi kutseka kumakhala:

• Kuchitapo kanthu;
• Choyendetsa choyendetsa.

Ma valve amphamvu omwe amagwiritsidwa ntchito pamadzi amodzi amagwiritsidwa ntchito pamtunda wotsika. Njira yowatsegula ndi kutsekera valavu ndi iyi: chipangizocho chimayambitsidwa ndi mphamvu yomwe imapezeka pamene imagwirizanitsidwa ndi magetsi.

Mosiyana ndi zomwe zapitazo, valavu yoyendetsa ndege imatsekedwa ndipo imatsegulidwa ndi mphamvu ya madzi, yomwe imayendetsedwa ndi magetsi. Chida ichi chikugwiritsidwa ntchito makamaka pamtambo wothamanga kwambiri. M'pofunika kukumbukira kuti ntchito yopanda mavuto ya valve solid valve (0.2 atm) ndi yofunika.

Malinga ndi malo opangira opaleshoni, valveid valves amagawidwa:

• Kawirikawiri kutseguka - popanda mphamvu yowonjezera ili pamalo otseguka, ndipo pamene zamakono zimaperekedwa, zimatsekedwa;
• Nthawi zambiri kutsekedwa - popanda mphamvu ya magetsi ili mu boma lotsekedwa, ndipo pamene mphamvu imaperekedwa, imatsekedwa;
• Bistable - amatha kusintha kuchoka pamalo amodzi kupita kumalo pansi pachitetezo choyendetsa.

Mitundu ya mapulogalamu a induction:

• DC - valve ili ndi mphamvu yaing'ono yamagetsi. Anagwiritsira ntchito kusintha kayendedwe kochepa;
• AC - ali ndi mphamvu yambiri yamagetsi a magetsi. Mukamagwiritsa ntchito magetsi ambiri, kuthamanga kwa valve kumawonjezeka, komwe kumapereka mphamvu yowonjezera.

Kuyika ma valve solenoid

Mwa njira yogwirizanitsa ndiipiipi imapezeka:

• Valenoid valve flanged kwa madzi;
• Vesi yotchinga.

Sungani ma valve solenoid paipi yoyamba kutsukidwa. Ndi zofunika kuti dongosolo likhale ndi fyuluta yakuda. Malo omwe ali ndiipi ayenera kusankhidwa kuti valavu ifike mosavuta. Komabe, chifukwa cha miyeso yake, zimakhala zosavuta kuziyika ngakhale pang'onopang'ono.

Malo a valve samakhudza ntchito ya chipangizocho, kotero icho chingakhale chirichonse. Ndi bwino kukumbukira kuti ma valavu a madzi omwe amafunika kutsogolo ayenera kuikidwa ndikuganizira momwe madzi akuyendera.

Chiwerengero cha ntchito

M'dziko lamakono, malo ogwiritsira ntchito magetsi a magetsi amathamanga kwambiri. Nthawi zambiri amaikidwa:

• Kuchita mafakitale - m'madzi ochapa osambitsa madzi, kuti asunge madzi oyenera m'magombe a mafakitale a mafuta ndi gasi, mankhwala ndi magetsi;
• Mukumanga nyumba - popanga dongosolo la "smart house", kuti athetse madzi otsika m'madzi;
• Maselo amadziwetsedwe - zotupa za solenoid zamadzi otentha ndi ozizira ndi timer zimayendetsa madzi ku magetsi a anthu;
• Mu kusamba - onetsetsani kuti ntchito yowonongeka kwa makina a panyumba ndi mafakitale , otsuka zitsamba , galimoto imatsuka;
• Mu magetsi oyamwa - yongolerani kudzazidwa kwa madzi ndi matanki ndi boilers;
• Mu machitidwe okulitsa - perekani zowonjezereka zowonongeka;
• Pamakisitini akuluakulu - ophika mikate, kuphatikiza khofi, maphika ophika, ndi zina zotero.

Kuyika ndi malangizo opangira

Magetsi a magetsi pamadzi panthawi ya kuika ndi opaleshoni amafunika kutsatira malamulo ena:

• Malamulo a chitetezo;
• Sizowonjezeka kuti mupange makonzedwewo, momwe chophimba cha valve chimakhala ngati chiwindi;
• Vuvuyo iyenera kukhazikitsidwa ndi kuchotsedwa mu dziko lopatsidwa mphamvu;
• Pambuyo pa valve solenoid, m'pofunika kukhazikitsa fyuluta kuti muteteze chotupa cha chipangizo chotsutsana ndi ingress ya zinthu zazikulu;
• Thupi la valve siliyenera kunyamula katundu wolemera waipiipi, komanso kutenga malo opotoza ndi kupukuta gawo la dongosolo;
• Malangizo a madzi akuyenda mu mapaipi ayenera kugwirizana ndi zizindikiro pa thupi la valve;
• Poika pamalo otseguka, mphamvu yothandizira magetsi imayenera kuwonjezeredwa ku mphepo yamkuntho;
• Monga chosindikizira m'magulu a thupi la valve ndi chitoliro zimalimbikitsidwa kugwiritsa ntchito tepi ya FSM;
• Mukamagwiritsa ntchito valve ndi mgwirizano wa flange, gwiritsani ntchito mphete yosindikiza kapena paronite;
• Mukamagwirizanitsa chipangizocho kumagetsi, makina osinthika omwe ali ndi mapulogalamu osachepera 1 mm amagwiritsidwa ntchito;
• Ntchito ya valve iyenera kuchitidwa malinga ndi malamulo ogwiritsira ntchito chipangizochi;
• Kamodzi pakatha miyezi itatu muyenera kuonetsetsa kuti odyetserako akugwedezeka, komanso kuyeretsani chophimba kuchokera ku dothi ndi fumbi.

Zomwe zimayambitsa kulephera

M'kupita kwanthaŵi, ngakhale zipangizo zodalirika zingathe kuwonongeka. Mavitamini a solenoid amadzimodzimodzi. Kusokonezeka kungayambitsidwe ndi zifukwa zingapo:

• Mphamvu yamagetsi sichifika pa valavu - imakhalapo ngati chingwe chimachoka pazitsulo zogwiritsa ntchito;
• Pa mphamvu yachibadwa chipangizocho sichigwira ntchito - kasupe akhoza kusweka, m'malo mwa solenoid amafunika;
• Palibe phokoso lopukuta pamene likuyang'ana - chophimba cha electromagnetic chatentha;
• Phando limene solenoid yavunda lakhala lotsekedwa - kuyeretsa dzenje kumafunikanso posadziwika bwino.

Kukonza bwino ndikutsatiridwa ndi machitidwe owonetsetsa kuti ntchito yodalirika yowonjezera nthawi yayitali imakhala yodalirika.
