N’chifukwa chiyani ma valve “amafa ali aang’ono?” Madzi amavumbula chinsinsi cha moyo wawo waufupi!

Mu 'nkhalango yachitsulo' ya mapaipi a mafakitale,mavavuamachita ngati ogwira ntchito yothira madzi chete, kulamulira kayendedwe ka madzi. Komabe, nthawi zambiri 'amafa ali aang'ono,' zomwe n'zomvetsa chisoni kwambiri. Ngakhale kuti ali m'gulu lomwelo, n'chifukwa chiyani ena amachita zimenezi?mavavuKodi mupuma pantchito msanga pamene ena akupitiriza kutumikira? Lero, tiyeni titsatire katswiri wowongolera madzi wa Waters kuti tipeze zoona zenizeni zomwe zili kumbuyo kwa nthawi yochepa ya moyo wamavavu.

Zifukwa zitatu zazikulu zavalavu"moyo waufupi"
Kupuma Movutikira Mpaka Kufa: Kulimbana Kwachiwiri kwa Kupanikizika Kwambiri ndi Dzimbiri Kupsinjika Kwambiri: Pamene kuthamanga kwa dongosolo kukupitirira malire a kapangidwe ka valavu,valavuThupi ndi zisindikizo zimapanikizika kwambiri, zomwe zimapangitsa kuti kapangidwe kake kasinthe komanso kulephera kutseka. Kugundana kwa nyundo yamadzi nthawi yomweyo kumakhala ngati kuvulala kwamkati, komwe kumatha kupangitsa kuti valavu isagwiritsidwe ntchito nthawi yomweyo. Kudzimbiritsa: Mu nyengo zovuta monga malo okhala ndi mankhwala ndi madzi a m'nyanja, zinthu zowononga zimagwira ntchito ngati manja ofewetsa mafupa, zomwe zimawononga pang'onopang'ono makulidwe a khoma la valavu (ndi dzimbiri lopitirira 0.5 mm pachaka), kufooketsa mphamvu yake, ndikupangitsa kubowoka ndi kutuluka. Madzi amamvetsetsa kuti zinthu ndizofunikira, ndipo ma valve ake apadera a alloy (monga Hastelloy ndi chitsulo cha duplex) ali ngati 'zishango zagolide,' zomwe zimawonjezera kupanikizika kwawo komanso kukana dzimbiri. Kugwira Ntchito Mopitirira Muyeso: Kudula Kopanda Chilungamo ndi Madzi Othamanga Kwambiri Zinthu Zosangalatsa Kuwonongeka: Tinthu tolimba (monga mchere wosungunuka ndi phulusa) kapena madzi othamanga kwambiri (monga nthunzi ndi madzi otsekeka) nthawi zonse timasaka pamwamba pa chisindikizo ndi chipinda cha valavu, timagwira ntchito ngati mipeni yambiri yojambulira yaying'ono. Pakapita nthawi, zochita izi zimapanga mipata yozama pamwamba pa chisindikizo, zomwe zimapangitsa kuti chisindikizo chilephereke. Malo otsekera a alloy olimba kwambiri a Waters (monga tungsten carbide ndi STL) ndi mapangidwe abwino a njira yoyendera madzi amagwira ntchito ngati 'malaya achitsulo' motsutsana ndi 'kudula zikwizikwi' kosalekeza kumeneku.

Kutsekeka kwa mpweya woipa: kutsekeka koopsa kwa zinyalala ndi kukula

Kulowa kwa zinyalala: Zinyalala zonyowa, dzimbiri, ndi zinthu zakunja zimatha kulowa mupaipi ndikukakamira pakati pa mpando wa valavu ndi pakati. Izi zingayambitse kuti valavu isatseke kapena kutseguka bwino, ndipo nthawi zina, zingawononge malo otsekera bwino. Kukhazikika kwapakati pa kristalo ndi kukula: Muzochitika zina (monga madzi ozizira kapena slurry), cholumikiziracho chingapangike kapena kukula mkati mwavalavu, kutseka bwino malo olumikizira ma valavu, zomwe zimapangitsa kuti pakhale kutsekeka pang'onopang'ono kapena kotheratu. Mapangidwe a madzi oletsa kutsekeka, monga ma valavu akuluakulu amtundu wa V ndi mapangidwe otsukira, amagwira ntchito ngati zida zothandiza pochotsa magazi oundana amenewa.

"Cholakwika" cha wogwiritsa ntchito chinapangitsa kuti moyo wa valavu ukhale wofulumira

Malinga ndiValavu yotseka madzi ya TWS, kukhalitsa kwa ma valve si ngozi, koma uinjiniya wamakina kuchokera ku kapangidwe, kusankha zinthu, kupanga ndi kugwiritsa ntchito:

 

Kufananiza Molondola, Kogwirizana ndi Zomwe Zili M'kati: Chitani kusanthula kwathunthu kwa momwe ntchito ikuyendera (kupanikizika, kutentha, pakati, kuchuluka kwa tinthu, ndi kuchuluka kwa ntchito) kuti musankhe mtundu woyenera wa valavu (valavu ya chipata, valavu ya dziko lonse, valavu ya mpira,valavu ya gulugufe) ndi zinthu. Zigawo Zapakati, Kuyesetsa Kukhala Wangwiro: Peyala yotsekera imapangidwa ndi aloyi wolimba wosawonongeka komanso wosagonjetsedwa ndi dzimbiri; tsinde la valavu limapangidwa ndi zinthu zolimba kwambiri zosagonjetsedwa ndi dzimbiri zokhala ndi chithandizo chapamwamba; zigawo zofunika kwambiri zonyamula kupanikizika zimatsimikiziridwa mwamphamvu kudzera mu kusanthula kwa zinthu zochepa (FEA). Luso, Kuwongolera Ubwino Kwambiri: Kupanga makina molondola kumatsimikizira kulekerera kolondola, ndipo kuyesa kosawononga (RT/UT/PT) kumachotsa zolakwika zamkati; njira iliyonse ndi kudzipereka ku kudalirika. Kusankha Mwanzeru, Kuyembekezera Tsogolo: Perekani malangizo osankha akatswiri ndi mayankho okonzedwa kuti muwonetsetse kuti mavalavu 'abadwa panthawi yoyenera, pamalo oyenera.'

Chitani bwino "mtima uliwonse wa mafakitale"

Kulephera kwa ma valve msanga ndi chizindikiro cha mavuto omwe angabwere chifukwa cha dongosolo ndipo kumatanthauza kutayika kwa zinthu ndi magwiridwe antchito. Mukasankha Madzi, mukusankha ukatswiri ndi kudzipereka kuti muwonjezere mphamvu zamadzimadzi m'machitidwe anu. Sitimangopereka zinthu zokhazikika za ma valve komanso timalimbikitsa mfundo za kayendetsedwe ka sayansi ndi ntchito zokhazikika. Pokhapokha pomvetsetsa, kulemekeza, ndi kuchitira bwino 'oyang'anira mafakitale' osalankhula awa ndi pomwe angagwire ntchito mokhazikika, moyenera, komanso kwanthawi yayitali m'maudindo awo, pamodzi ndikuwonetsetsa kuti njira zamafakitale zikuyenda bwino!
