Flowrox anakonza mapangidwe atsopano a valve yachipata cha slurry mpeni. Inanena kuti idathetsa kufunikira kwa nsanja ya silinda ndikuyikanso masilindala awiri a actuator mbali iliyonse ya valve.
Mavavu a zipata za mpeni amapezeka kawirikawiri m'ma concentrators, tailings ndi mayendedwe amatope, ndi ntchito za leaching.
Malinga ndi kampani ya ku Finnish, mapangidwe a nsanja a actuators achikhalidwe nthawi zambiri amakhala oyenera ma valve a pachipata, koma mpaka kukula kwake. "DN yokulirapo, valavu imakwera," adatero Flowrox.
"Tiyerekeze kuti tikufuna valavu ya DN 1200," inatero kampaniyo. "Pogwiritsa ntchito pulani ya nsanja, izi zikutanthauza kuti valavu idzakhala yokwera kwambiri pamalo otseguka: 5.6 m! Kutalika kwapamwamba kwambiri kumatanthauzanso malo apamwamba a mphamvu yokoka. Izi zimapangitsa kuti valavu ya chipata cha mpeni ikhale yovuta kugwira ntchito, yosakhazikika panthawi ya msonkhano, ndipo Itos imakhala yovuta kuisamalira. Mwanjira ina, sizili zotetezeka. ”
Mapangidwewo adachotsa nsanja ya silinda ya valve pachipata cha mpeni ndipo m'malo mwake adayikanso masilindala awiri mbali iliyonse ya valve, idatero. Kutengera chitsanzo pamwambapa, valavu ya chipata cha mpeni ya Flowrox DN 1200 tsopano imayeza 3.6 m pamalo otseguka: mamita awiri kuchepera kuposa kapangidwe ka nsanja.
Malinga ndi Flowrox, kutalika kwa valve m'munsi kumatanthauza malo otsika a mphamvu yokoka. Izi zimapangitsa kuti valavu yachipata cha mpeni ikhale yokhazikika komanso yotetezeka.
"Sikuti ndizosavuta kukhazikitsa, zimafunanso malo ochepa pamwamba pa valve," inatero kampaniyo. “Malo onse okonzerako ali pansi pa 2 m kuchokera pansi, kotero ndi osavuta kufikako. Momwemonso, kulumikizana kwina konse kumatha kuchitidwa pansi kapena kuchokera pansi m'malo mwamlengalenga.
Pankhani ya mapangidwe a nsanja, ntchito yokonza nthawi zambiri imayenera kuchitidwa pa mtunda wa 3-4 m kuchokera pansi, zomwe zimabweretsa zoopsa zachitetezo, zimafunikira njira zowonjezera zachitetezo ndikuwononga nthawi yambiri. ”
Mwachizoloŵezi, thupi la valve limapangidwa ndi zigawo ziwiri ndikumangirira palimodzi, zomwe zimayambitsa kutayikira ndi ntchito yambiri yoboola panthawi yokonza.
Thupi la valve la Flowrox slurry mpeni lachipata la valavu limaponyedwa kwathunthu mu chidutswa chimodzi, zomwe zikutanthauza kuti palibe chiwopsezo chotuluka kuchokera ku thupi la valve. Zimapangitsanso kuti pakhale mawonekedwe osavuta, olimba komanso magawo ochepa, zomwe zikutanthauza kupulumutsa zida zosinthira ndi nthawi yokonza.
Kampaniyo inamaliza kuti: "Mavavu a zipata za Flowrox slurry mpeni ndizophatikizika, zosavuta kuziyika komanso zosavuta kuzisamalira. Mavavuwa a DN 900-DN 1500 amatha kuthana ndi zovuta kuchokera pa bar 10 komanso zotsika mpaka 4 bar, kutengera kukula kwake.
