Zochita 4-1: Kuwongolera Kwachindunji Pogwiritsa Ntchito Ma valve Oyendetsa Oyendetsa
2024-07-29Kumvetsetsa Mavavu Oyendetsa Oyendetsa
Ma valve oyendetsa ndege (POVs) ndi mtundu wa valavu yowongolera yomwe imagwiritsa ntchito valavu yaing'ono, yothandizira (woyendetsa ndege) kuti ayendetse kayendedwe ka madzi kudzera mu valve yaikulu yaikulu. Valavu yoyendetsa, yoyendetsedwa ndi chizindikiro chokakamiza kapena zolowetsa zina, imayendetsa malo a spool kapena pistoni ya valavu yayikulu. Njira yowongolerera yosalunjika iyi imapereka zabwino zingapo, kuphatikiza kuwongolera kolondola, kukhudzika kowonjezereka, komanso kutha kuthana ndi kuthamanga kwambiri.
Momwe Mavavu Oyendetsa Oyendetsa Amagwirira Ntchito
1.Pilot Valve activation:Chizindikiro choponderezedwa, chizindikiro chamagetsi, kapena kulowetsa kwamakina kumayambitsa valavu yoyendetsa.
2.Pilot Valve Imawongolera Vavu Yaikulu:Kuyenda kwa valavu yoyendetsa ndege kumapangitsa kuyenda kwamadzimadzi kupita ku diaphragm kapena pistoni mu valavu yayikulu.
3.Main Valve Position:Kusiyanitsa kwapanikizidwe komwe kumapangidwa ndi valavu yoyendetsa ndege kumapangitsa kuti valavu yayikulu itsegule kapena kutseka, kuwongolera kutuluka kwa mtsinje waukulu wamadzimadzi.
Ubwino wa Mavavu Oyendetsa Oyendetsa
• Kuwongolera Molondola:Ma valve oyendetsa ndege amawongolera bwino kayendedwe ka madzimadzi, kuwapangitsa kukhala abwino kwa mapulogalamu omwe amafunikira kuwongolera bwino.
• Mayendedwe Apamwamba:Ma valve awa amatha kuthana ndi kuchuluka kwa kuthamanga kwambiri kwinaku akuwongolera moyenera.
• Kugwiritsa ntchito kutali:Ma valve oyendetsa ndege amatha kuwongoleredwa patali pogwiritsa ntchito zizindikiro zosiyanasiyana zolowera, zomwe zimathandiza kuti ziziyenda zokha ndikuphatikizana ndi machitidwe akuluakulu owongolera.
• Kuchulukirachulukira:Ma valve oyendetsa ndege amakhudzidwa kwambiri ndi kusintha kwa zizindikiro zolowera, zomwe zimalola nthawi yoyankha mofulumira.
• Zomwe Zachitetezo:Ma valve ambiri oyendetsa ndege amaphatikizapo zinthu zotetezera monga njira zolephera kuteteza zinthu zoopsa.
Kugwiritsa Ntchito Ma Valves Oyendetsa Oyendetsa
Ma valve oyendetsa ndege amagwiritsa ntchito kwambiri m'mafakitale osiyanasiyana, kuphatikizapo:
• Makina a Hydraulic:
° Kuwongolera masilinda a hydraulic kuti akhazikike bwino
° Kuwongolera kuthamanga kwa ma hydraulic circuits
° Kukhazikitsa ntchito zovuta zotsatizana
• Pneumatic Systems:
° Kuwongolera ma actuators a pneumatic pantchito zodzichitira
° Kuwongolera kuthamanga kwa mpweya m'mabwalo a pneumatic
• Kuwongolera Njira:
° Kuwongolera kuchuluka kwa kayendedwe ka mankhwala
° Kuwongolera kuthamanga kwa mapaipi
° Kusunga kutentha kwa mafakitale
Zochita Zolimbitsa Thupi ndi Malingaliro
Kuti mumalize masewero olimbitsa thupi 4-1, ganizirani ntchito ndi zinthu zotsatirazi:
• Dziwani Zigawo:Dzidziweni nokha ndi zigawo zosiyanasiyana za valve yoyendetsa ndege, kuphatikizapo valavu yoyendetsa ndege, valavu yaikulu, ndi ndime zolumikizira.
• Kumvetsetsa Mfundo Yoyendetsera Ntchito:Gwirani mfundo zazikuluzikulu za momwe kusiyanasiyana kwa kuthamanga ndi kutuluka kwamadzimadzi kumayenderana kuti muwongolere valavu yayikulu.
• Unikani Mitundu Yosiyanasiyana:Onani mitundu yosiyanasiyana ya ma valve oyendetsa ndege, monga ma valve olipidwa, owongolera, komanso oyendetsedwa ndi magetsi.
• Ganizirani Zofunsira:Ganizirani za ntchito zomwe mavavu oyendetsa ndege angapindule nawo komanso momwe angathandizire kukonza magwiridwe antchito.
Kupanga Control Circuit:Pangani hydraulic yosavuta kapena pneumatic circuit yomwe imaphatikizapo valavu yoyendetsa ndege kuti muyang'ane ndondomeko kapena ntchito inayake.
Mafunso Omwe Angathe Kuchita Zolimbitsa Thupi
• Kodi valavu yoyendetsa ndege imasiyana bwanji ndi yachindunji?
• Kodi ubwino wogwiritsa ntchito valavu yoyendetsedwa ndi woyendetsa mu hydraulic system ndi yotani?
• Pangani valavu yoyendetsedwa ndi woyendetsa ndege kuti muyendetse liwiro la silinda ya hydraulic.
• Fotokozani mmene valavu yoperekera chithandizo yoyendetsedwa ndi woyendetsa ndege imagwirira ntchito komanso ntchito yake pachitetezo.
• Kambiranani zinthu zomwe zimakhudza kusankha valavu yoyendetsa ndege pa ntchito inayake.
Mukamaliza Exercise 4-1, mumvetsetsa bwino mfundo, magwiritsidwe, ndi maubwino a ma valve oyendetsa ndege. Kudziwa izi kukupatsani mphamvu zopanga ndi kukhazikitsa njira zowongolera zogwira ntchito m'mafakitale osiyanasiyana.
Zindikirani:Kuti mupereke yankho logwirizana kwambiri, chonde perekani zambiri za zomwe mukufuna kuchita, monga:
• Mtundu wamadzimadzi omwe amawongoleredwa (mafuta a hydraulic, mpweya, etc.)
• Mulingo wofunidwa wowongolera (kuyatsa/kuzimitsa, molingana, ndi zina zotero)
• Zoletsa zilizonse kapena zolepheretsa
Ndi chidziwitso ichi, nditha kupereka chitsogozo chokhazikika komanso zitsanzo.
