Ma Vavu a Gulugufe Olimbana ndi Kulemera Kwambiri m'Masiteshoni a Madzi

Mu mafakitale opangira magetsi pogwiritsa ntchito madzi, kuonetsetsa kuti madzi akuyenda bwino komanso modalirika ndikofunikira kwambiri kuti zipangizo zizitetezedwa komanso kuti ntchito ziziyenda bwino. Chimodzi mwa zinthu zofunika kwambiri zomwe zimagwiritsidwa ntchito pa izi ndi valavu ya gulugufe yolimbana ndi kulemera kwake. Mtundu uwu wa valavu umagwira ntchito yofunika kwambiri pakutseka kwadzidzidzi, kulamulira kayendedwe ka madzi, komanso chitetezo cha makina, makamaka m'malo opangira magetsi pogwiritsa ntchito madzi apakati komanso akuluakulu.
Kapangidwe ndi Mfundo Yogwirira Ntchito
Valavu ya gulugufe yolimbana ndi kulemera kwakukulu imakhala ndi thupi la valavu, diski, shaft, sealing system, hydraulic kapena electric actuator, ndi makina olimbana ndi kulemera. Valavu ya valavu imazungulira shaft yapakati kuti itsegule kapena kutseka njira yamadzi.
Chinthu chofunika kwambiri ndi chipangizo choletsa kulemera kwa magetsi, chomwe chimapereka mphamvu yotseka yokha. Pakagwiritsidwa ntchito bwino, valavu imatsegulidwa ndi mphamvu ya hydraulic kapena actuator yamagetsi. Pamene magetsi alephera kapena zinthu zadzidzidzi zikuchitika, actuator imatuluka, ndipo counterweight imagwiritsa ntchito mphamvu yokoka kuti itseke valavu mwachangu.
Kutseka kumeneku kothandizidwa ndi mphamvu yokoka kumaonetsetsa kuti valavuyo imagwira ntchito yokha popanda mphamvu zakunja, zomwe zimawonjezera chitetezo.
Ntchito Zofunika Kwambiri mu Zomera Zamagetsi Ochokera Kumadzi
1. Kuzimitsa kwadzidzidzi
Chimodzi mwa ntchito zofunika kwambiri za valavu ya gulugufe yolimbana ndi kulemera kwake ndikutseka mwachangu panthawi yamavuto monga:
Turbine yothamanga kwambiri
Kukana katundu
Kuphulika kwa mapaipi
Mwa kutseka kuyenda kwa madzi mwachangu, kumateteza ma turbine, ma jenereta, ndi ma penstock ku kuwonongeka kwakukulu.
2. Kupatula Madzi Oyenda
Valavu nthawi zambiri imayikidwa pamalo olowera ma turbine kapena m'mphepete mwa penstocks kuti ipatule magawo a dongosololi panthawi ya:
Kukonza
Kuyendera
Kusintha zida
3. Kulamulira Hammer ya Madzi
Makina olimbana ndi kulemera koyenera amatha kuwongolera liwiro lotseka la valavu, kuchepetsa chiopsezo cha nyundo yamadzi—kukwera kwadzidzidzi kwa kuthamanga kwa mpweya komwe kungawononge mapaipi ndi zida.
Ubwino
Kudalirika Kwambiri
Popeza njira yotsekera imadalira mphamvu yokoka, valavu imakhalabe yogwira ntchito ngakhale mphamvu ikalephera kugwira ntchito.
Kuyankha Mwachangu
Choletsa kulemeracho chimalola kutsekedwa mwachangu, komwe ndikofunikira poteteza zida zofunika kwambiri pakagwa ngozi.
Kapangidwe Kosavuta Komanso Kolimba
Poyerekeza ndi zida zina zozimitsa, ma valve a gulugufe ali ndi kapangidwe kosavuta, zomwe zimapangitsa kuti:
Zosavuta kusamalira
Yolimba pansi pa mikhalidwe ya kupanikizika kwambiri
Yotsika Mtengo
Amapereka mgwirizano wabwino pakati pa magwiridwe antchito ndi mtengo, makamaka mapaipi akuluakulu.
Mapulogalamu
Ma valve a gulugufe olemera amagwiritsidwa ntchito kwambiri m'mitundu yosiyanasiyana ya mapulojekiti amagetsi amadzi, kuphatikizapo:
Malo opangira magetsi apakati ndi akuluakulu
Malo osungira magetsi opompa
Mapulojekiti okonzanso malo akale opangira magetsi
Kupatutsa madzi ndi njira zothirira
Zoganizira za Kapangidwe
Posankha ndi kupanga valavu ya gulugufe yolimbana ndi kulemera, zinthu zingapo ziyenera kuganiziridwa:
M'mimba mwake wa valavu ndi kupanikizika
Nthawi yotseka ndi kuwongolera liwiro
Kutseka bwino (kutseka kwa chitsulo ndi chitsulo kapena rabala)
Kudalirika kwa dongosolo la hydraulic
Kuphatikiza ndi machitidwe owongolera zomera
Kapangidwe ka uinjiniya koyenera kumatsimikizira magwiridwe antchito abwino komanso moyo wautali wautumiki.
Valavu ya gulugufe yolimbana ndi kulemera kwake ndi chipangizo chofunikira kwambiri chotetezera ndi chowongolera m'malo opangira magetsi pogwiritsa ntchito madzi. Kuthekera kwake kutseka zokha komanso modalirika pazochitika zadzidzidzi kumapangitsa kuti ikhale yofunika kwambiri poteteza zida ndi antchito. Ndi zabwino monga kudalirika kwambiri, kapangidwe kosavuta, komanso kuwongolera bwino kayendedwe ka madzi, ikupitilirabe kukhala chisankho chokondedwa muukadaulo wamakono wamagetsi pogwiritsa ntchito madzi.
