Limit Switch Box: Chitsogozo Chokwanira
M'makina amakono opanga makina opangira ma valve ndi makina owongolera ma valve, kuwonetsetsa kuwunika kolondola kwa ma valve ndikofunikira. Amalire kusintha bokosiimagwira ntchito yofunika kwambiri pakuchita izi popereka ndemanga zodalirika kwa ogwira ntchito ndi machitidwe olamulira. Kaya m’mapaipi amafuta ndi gasi, m’malo oyeretsera madzi, kapena m’mafakitale opangira mankhwala, chipangizochi chimaonetsetsa kuti ma valve ndi otetezeka, olondola, ndiponso osavuta kufufuza.
Nkhaniyi ikufotokoza mwatsatanetsatane bokosi losinthira malire, momwe limagwirira ntchito, zigawo zake zazikulu, mitundu yosiyanasiyana, ndikugwiritsa ntchito m'mafakitale osiyanasiyana. Pamapeto pake, mudzakhala mukumvetsetsa bwino chifukwa chake chipangizochi chili chofunikira pakuwongolera njira.
Kodi Limit Switch Box ndi chiyani?
Bokosi losinthira malire ndi chipangizo chophatikizika chomwe chimayikidwa pamwamba pa ma actuators kapena ma valve. Ntchito yake yayikulu ndikuwonetsa ngati valve ili pamalo otseguka kapena otsekedwa. Imatembenuza makina a tsinde la valve kapena shaft ya actuator kukhala chizindikiro chamagetsi chomwe chingatumizedwe ku distributed control system (DCS), programmable logic controller (PLC), kapena zizindikiro zowonetsera kwa ogwira ntchito zomera.
M'mawu osavuta, imakhala ngati "maso" a dongosolo la valve. Pamene chowongolera chimasuntha valavu, bokosi losinthira malire limatsimikizira kuti ogwira ntchito amadziwa bwino lomwe valve ili.
Zolinga zazikulu
- Mayankho a Valve Position- Amapereka zizindikiro zamagetsi kuti azilamulira zipinda ngati valve ili yotseguka kapena yotsekedwa.
- Chitetezo Chitsimikizo- Imaletsa magwiridwe antchito olakwika omwe angayambitse kutayikira, kutayikira, kapena ngozi.
- Automation Integration- Imathandizira kulumikizana ndi ma PLCs ndi ma SCADA machitidwe owongolera okha.
- Chizindikiro Chowoneka- Mabokosi ambiri amakhala ndi zizindikiro zamakina (mwachitsanzo, mivi yofiyira/yobiriwira kapena domes) kuti muwunikire mosavuta patsamba.
Kodi Limit Switch Box Imagwira Ntchito Motani?
Mfundo yogwirira ntchito ya bokosi losinthira malire ndiyosavuta, komabe kudalirika kwake kumapangitsa kukhala kofunikira.
- Mechanical Movement- Pamene actuator imatsegula kapena kutseka valve, shaft kapena tsinde imazungulira kapena imayenda motsatira.
- Njira ya Cam- M'kati mwa bokosi losinthira malire, kamera yoyikidwa pa shaft imazungulira moyenerera.
- Sinthani Kuyambitsa- Kamera imagwira ntchito ndi maswiti ang'onoang'ono, masensa oyandikira, kapena masensa maginito mkati mwa bokosi.
- Kutumiza kwa Signal- Akangotsegulidwa, masinthidwewa amatumiza chizindikiro chamagetsi kuti awonetse malo a valve (otseguka / otsekedwa kapena apakati).
- Ndemanga ku Control System- Chizindikirocho chimatumizidwa kumagulu owongolera, SCADA, kapena zowonetsera zakomweko.
Chitsanzo Chosavuta
- Vavu yotseguka kwathunthu → Cam imayambitsa chosinthira "chotsegula" → Chizindikiro chobiriwira chatumizidwa.
- Vavu yotsekedwa kwathunthu → Cam imayambitsa chosinthira "chotsekedwa" → Chizindikiro chofiira chatumizidwa.
- Vavu pakusintha → Palibe chizindikiro chotsimikizika, kapena m'mitundu yapamwamba, mayankho a analogi owonetsa malo enieni.

Mafunso Ofunsidwa Kawirikawiri (FAQs)
1. Kodi pali kusiyana kotani pakati pa kusintha kwa malire ndi bokosi losinthira malire?
Kusintha kwa malire ndi chipangizo chimodzi chomwe chimazindikira kusuntha kwamakina, pomwe bokosi losinthira malire limakhala ndi masiwichi / masensa angapo okhala ndi mayankho owunikira ma valve.
2. Kodi bokosi losinthira malire lingagwiritsidwe ntchito panja?
Inde, malinga ngati ili ndi IP67 kapena kupitilira kwanyengo.
3. Kodi ndingadziwe bwanji ngati bokosi langa losinthira malire lili lolakwika?
Yang'anani ngati mawonekedwe a valve sikugwirizana ndi momwe ma valve akuyendera, kapena ngati palibe zizindikiro zomwe zimatumizidwa ngakhale kuyenda.
4. Kodi mabokosi onse osinthira malire saphulika?
Ayi. Ndi mitundu yokhayo yovomerezeka ndi mavoti a ATEX kapena IECEx yomwe ili yoyenera malo owopsa.
5. Kodi bokosi losinthira malire limakhala lotani?
Nthawi zambiri 5-10 zaka kutengera kagwiritsidwe, chilengedwe, ndi kukonza.
Mapeto
Bokosi losinthira malire limatha kuwoneka ngati gawo laling'ono, koma zotsatira zake pachitetezo cha mafakitale ndikuchita bwino ndizofunikira. Kuchokera pakupereka ndemanga yeniyeni ya ma valve kuti athe kugwirizanitsa ndi machitidwe ovuta olamulira, zimatsimikizira kuti ntchito zimakhala zodalirika komanso zotetezeka.
Pamene mafakitale akupitilira kusinthika kupita ku makina anzeru, mabokosi amakono osinthira malire okhala ndi zowunikira zapamwamba komanso kulumikizana kwa digito kudzakhala kofunikira kwambiri. Kusankha chitsanzo choyenera cha ntchito yanu si nkhani yongogwira ntchito komanso chitetezo komanso nthawi yayitali.
