Vavu ya Mpira
UPVC 1-2 Inchi ~ 4 Inchi Pneumatic Actuator Mndandanda wa Mtengo Wowona wa Union Ball Valve
Zamgulu Mbali
1) The actuator wadutsa kuyezetsa zotsatira, kuyezetsa asidi alkali, ndi zinthu zimakwaniritsa SGS zofunika.
2) Kutsegula kwa valve kumatha kusinthidwa kuchokera ku 15 mpaka 90 madigiri.
3) Zinthuzo zimasinthidwa ndi nano kuti zithandizire kukana kwazinthu komanso kukana kwamphamvu.
4) Kuonjezera ma anti UV absorbers ndi ma antioxidants kuzinthu zopangira kuti apititse patsogolo kukana kwa nyengo ndi kukalamba.
5) 100% kuyezetsa ntchito musanapereke.
Kodi valavu ya mpira wa pneumatic ndi chiyani?
Ma valve a mpira wa pneumatic amagwiritsidwa ntchito kuwongolera kuyenda kwa media (zamadzimadzi kapena gasi) pogwiritsa ntchito mpira wozungulira wokhala ndi bore. Pneumatic actuators amawongolera ma valve a mpira posintha mphamvu ya mpweya woponderezedwa kukhala woyenda wamakina. Mpira wozungulira umayendetsedwa ndikutembenuzidwa ndi pneumatic actuator.
Kodi pali kusiyana kotani pakati pa single acting ndi double acting pneumatic actuator ball valve?
Kuchita kamodzi komanso kawiri mu valavu ya mpira wa pneumatic kumatanthauza kuti woyendetsa pneumatic wa valavu ya mpira wa pneumatic akhoza kugawidwa kukhala imodzi yokha ndi iwiri. Kusiyana kwake ndikuti masilinda ochita kamodzi amakhala ndi akasupe ndipo masilinda ochita kawiri alibe akasupe. Chifukwa chake, mtengo wa makina opanga ma pneumatic actuators ndi wokwera kuposa ma pneumatic actuators awiri.
Kodi masilinda ang'onoang'ono ndi masilinda apawiri ndi chiyani?
Masilinda omwe amagwira ntchito imodzi ali ndi chipinda chimodzi chokha chomwe chimatha kudyetsedwa ndi mpweya woponderezedwa kuti azindikire kuyenda mbali imodzi. Ndodo yake ya pisitoni imatha kukankhidwa kumbuyo ndi mphamvu zakunja; nthawi zambiri ndi mphamvu ya masika, kuthamanga kwa diaphragm, mphamvu yokoka, etc..
Pawiri-kuchita yamphamvu amatanthauza zipinda ziwiri akhoza motero athandizira wothinikizidwa mpweya, kukwaniritsa njira ziwiri kayendedwe ka yamphamvu. Mapangidwe ake amatha kugawidwa mumitundu iwiri ya pisitoni, mtundu umodzi wa pisitoni, mtundu wa pistoni wapawiri, mtundu wopondera komanso wosakhazikika.
Ngati pali kusagwira bwino ntchito kwa gasi kapena kulephera kwadzidzidzi kwamagetsi, makina a pneumatic actuator amangobwerera kumalo otseguka pogwiritsa ntchito kasupe, omwe nthawi zambiri amatchedwa valve yotseka mwadzidzidzi, ndipo idzabwerera. ku chikhalidwe chokhazikitsidwa. Ngati itayimitsidwa, ibwerera ku malo osagwira ntchito, omwe nthawi zambiri amagwiritsidwa ntchito m'malo oopsa.
Mwachitsanzo, ponyamula mpweya woyaka kapena zinthu zamadzimadzi zoyaka moto, pomwe gwero la gasi litatayika ndipo pakachitika ngozi, choyambitsa chimodzi chokha chimatha kukhazikitsidwanso kuti chichepetse ngoziyo, pomwe chowotcha chapneumatic chochita kawiri sichingakhazikitsidwenso.
Momwe mungasankhire
Silinda yochita kamodzi ndi silinda ya silinda yochita kawiri ndizofanana, makamaka potengera zomwe wogwiritsa ntchito akufuna kusankha. Kuchita kamodzi kokha kumagwiritsidwa ntchito podula mphamvu ndi kudula kwa gasi, valavu imayenera kutsegula kapena kutseka.
Chifukwa chiyani cholumikizira magetsi cha PVC chowonadi cholumikizira mpira sichingathe kuthandizidwa ndi mpweya wabwino?
PVC wowona mgwirizano mpira valavu ndi wothinikizidwa mpweya kupeza mphamvu kuyendetsa valavu lophimba kapena kusintha ulamuliro. Ubwino wa gwero la mpweya umakhudza mwachindunji kugwiritsa ntchito valve. Gwero la mpweya wabwino, lokhazikika, lapamwamba kwambiri likhoza kuonjezera moyo wautumiki wa valve, pamene gwero la mpweya silili lokhazikika lidzawononga mwachindunji valve, kuchepetsa moyo wautumiki.
Kuthamanga kwa mpweya wabwino kudzakhala kokhazikika, nthawi zambiri pakati pa 5-6bar. Ndi mavavu omwe amagwira ntchito imodzi, kuthamanga kwa mpweya wochepera 5bar kungapangitse kuti valavu isatsegulidwe. pamene ma valve angapo amagwiritsidwa ntchito nthawi imodzi, mpweya wa compressor udzakhala ndi mphamvu yofananira, yomwe imatsimikizira kuti mphamvu ya actuator ikhoza kuchitika. Pa nthawi yomweyi ma valve ambiri amatseguka kapena otsekedwa; mpweya wopanikizidwa uziziritsidwa, kusefedwa, kutsukidwa ndi madzi ndi zonyansa. Mpweya wolowetsa mpweya wa vavu kuti uyikidwe Air kusefera katatu: fyuluta, chowongolera, fyuluta yamafuta. Kutumiza mtunda wautali wa mpweya wothinikizidwa, mutha kugwiritsa ntchito malowa pafupi ndi kuyika machubu ena a mpweya kuti mukhazikitse kuthamanga kwa mpweya. Chitoliro cha mpweya ndi zopangira mpweya zisatayike.
Kugwira ntchito bwino kwa mavavu a mpira wa PVC kumafuna kuthandizidwa ndi mpweya wabwino kwambiri.
