Pamsonkhano waposachedwa wa kukonza ma hydraulic, wina adandifunsa malingaliro anga okhudza valavu yodzipatula pamizere yolowera pampu komanso ngati kuli koyenera kugwiritsa ntchito ma valve okwera mtengo kwambiri poyerekeza ndi ma valve agulugufe omwe nthawi zambiri amakhala otsika mtengo. Muzu wa vuto ili ndi zotsatira zoipa za chipwirikiti mu mzere wokokera mpope. Mtsutso wogwiritsira ntchito valavu ya mpira monga valavu yodzipatula kwa mzere wolowera ndikuti pamene valavu ya mpira imatsegulidwa, dzenje lonse la valve lingagwiritsidwe ntchito pakuyenda kwa mafuta. Choncho, ngati muyika valavu ya mpira wa 2-inch mu mzere wa 2-inch, pamene valavu imatsegulidwa, idzawoneka ngati palibe (makamaka kuchokera pakuwona mafuta).
Kumbali ina, valavu ya gulugufe sidzaza ndi mabowo. Ngakhale atatsegulidwa kwathunthu, mawonekedwe agulugufe amakhalabe mu dzenje ndikuwonetsa kuletsa pang'ono, komwe kumakhala kosakhazikika. Izi zingayambitse chipwirikiti, zomwe zingapangitse mpweya wosungunuka kuchoka mu njira yothetsera vutoli. Ngati izi zitachitika, thovuzi zimaphulika zikakumana ndi kukakamizidwa pa pompu. Mwa kuyankhula kwina, ma valve a butterfly angayambitse cavitation.
Kotero ndi iti yomwe ili yabwino kwambiri: valavu ya mpira kapena valavu ya butterfly? Chabwino, monga mavuto ambiri ndi ma hydraulics, zimatengera. M'dziko labwino, nthawi zonse ndimasankha valavu ya mpira pamaso pa gulugufe. Kwa chitoliro cholowetsera chokhala ndi mainchesi atatu, palibe kutayika kwa ndalama pochita izi.
Koma mukapeza mainchesi 4, mainchesi 6 ndi mainchesi 8 m'mimba mwake, mavavu a mpira ndi okwera mtengo kwambiri poyerekeza ndi mavavu agulugufe. Amatenganso malo ochulukirapo, makamaka kutalika konse. Chifukwa chake, pamapulogalamu am'manja, mwachitsanzo, sikuti mtengo wa valavu ya mpira wokhala ndi m'mimba mwake waukulu ndi wokwera kwambiri, koma sipangakhale malo okwanira pakati pa tanki ndi polowera kuti muyike.
Pali njira yachitatu. Anthu ambiri amakhulupirira molakwika kuti valavu yodzipatula ndiyofunikira, koma kwenikweni sichoncho, koma pali zochepa zochepa.
Funso loyamba lomwe likutsatira ndi momwe mungasinthire mpope ngati palibe valve yodzipatula pamzere wolowera. Pali mayankho awiri. Choyamba, ngati pampu ili ndi vuto lalikulu ndipo ntchito yanu ndi "yolondola", muyenera kugwiritsa ntchito ngolo yosefera kuti mutenge mafuta kuchokera mu thanki ndikutsanulira mu chidebe choyera kapena chidebe china choyenera. Kenako tanki yamafuta iyenera kutsukidwa bwino, pompayo iyenera kusinthidwa, kenako ngolo yosefera iyenera kugwiritsidwa ntchito kupopera mafutawo (poganiza kuti akugwirabe ntchito) kubwerera ku thanki.
Chotsutsa chambiri pa izi ndi: O, tilibe nthawi yochitira izi!q kapena pPalibe 10, 20, kapena ng'oma zoyera zambiri zatizungulira.q Kwa iwo amene safuna kugwira ntchito yoyenera, njira imodzi ndiyo kuyika. Permeate yonse imangokhala pamutu wa thanki yosungiramo, ndiyeno chotsukira chotsuka cha mafakitale chimalumikizidwa ndi mpweya wa thanki. Mukasintha mpope, yatsani chotsukira chotsuka, ndiyeno bwerezani ntchitoyo pamene zinyalala za kulephera kwa mpope wam'mbuyomu zimapangitsa kuti mpope wosunga zobwezeretsera ulephereke.
Zachidziwikire, pali zina, monga kujambula pampu yopitilira imodzi kuchokera ku tanki imodzi, kapena kupopera mafuta okwana magaloni 3000 kuchokera mu thanki sikutheka. Nthawi zina valavu yodzipatula pamzere wolowera imafunika. Ngati ndi choncho, ndi bwino kuonetsetsa kuti ali ndi masinthidwe oyandikira kuti ateteze kuyambitsa mpope mutatha kutseka valve.
Njira yanga yomwe ndimakonda ndikuyika ma valve a mpira kapena ma valve agulugufe, ngati n'kotheka. Ngati mukuyenera kukhala nayo, gwiritsani ntchito valavu ya mpira ngati mtengo kapena malo sizovuta. Komabe, ngati ena mwa mavutowa ali vuto, valavu gulugufe ndi njira yokhayo.
Nthawi zambiri, ma valve a butterfly amagwiritsidwa ntchito ngati ma valve odzipatula papampu. Zofukula zazikulu zama hydraulic ndi chitsanzo chofala. Amakhala ndi mapampu angapo akuyamwa kuchokera mu tanki yayikulu kudzera pamzere wolowera m'mimba mwake, ndipo palibe malo ochulukirapo-zigawo zonse zomwe zimapatula njira yabwino kwambiri (palibe valavu kapena valavu ya mpira) imachotsedwa.
Sindikukumbukira kuti ndinawonapo mpope pachokumba chachikulu cha hydraulic sichikuwonongeka ndi kukokoloka kwa cavitation, pomwe kuwonongeka kumeneku kumatha kuonedwa ngati kuvala kwakukulu. Kodi kuwonongeka kwa cavitation kumeneku kungabwere chifukwa cha chipwirikiti chomwe chimabwera chifukwa cha valavu ya butterfly? N’zoona kuti zingatheke, koma pangakhale zifukwa zina zambiri. Njira yokhayo yotsimikizira ndikufanizira mapampu awiri omwe amagwira ntchito mofanana - imodzi ndi valve ya butterfly ndi ina yopanda valve ya butterfly.
Brendan Casey ali ndi zaka zopitilira 20 pakukonza, kukonza ndi kukonza zida zam'manja ndi mafakitale. Zambiri pakuchepetsa mtengo wogwirira ntchito komanso kukweza mtengo…
