Mapampu a Slurry

Kodi pampu ya slurry ndi chiyani?

Mapampu otayirira amapangidwa kuti aziyenda movutikira, zokhuthala, kapena zolimba zodzaza ndi mapaipi. Chifukwa cha zinthu zomwe amagwiritsa ntchito, zimakhala zolemetsa kwambiri, zopangidwa ndi zipangizo zolimba zomwe zimakhala zolimba kuti zigwire madzi otsekemera kwa nthawi yaitali popanda kuvala mopitirira muyeso.

Kodi zimagwira ntchito bwanji?

Pali mitundu ingapo yamapampu a slurry. M'gulu la mapampu centrifugal, iwo amakhala gawo limodzi lomaliza loyamwitsa kasinthidwe. Komabe, pali zinthu zingapo zapadera zomwe zimasiyanitsa ndi zovomerezeka kapena zachikhalidwe pomaliza zopopera. Nthawi zambiri amapangidwa ndi zida zachitsulo za nickel, zomwe zimakhala zolimba kwambiri kuti zichepetse kuvala kwa abrasive pazigawo zapampu. Izi ndizovuta kwambiri kotero kuti mbali zake nthawi zambiri sizingapangidwe pogwiritsa ntchito zida zamakina wamba. M'malo mwake zigawozo ziyenera kupangidwa ndi makina opukutira, ndipo ma flanges amakhala ndi mipata kuti avomereze mabawuti kotero kuti kubowola mabowo sikufunika. Monga m'malo mwa chitsulo cholimba cha nickel, mapampu a slurry amatha kukhala ndi mphira kuti atetezedwe kuti asavale. Kusankhidwa kwa chitsulo cha nickel kapena mphira wamtundu wa pampu wotere kumadalira momwe tinthu tating'onoting'ono ta slurry, kukula kwake, kuthamanga, ndi mawonekedwe ake (zozungulira mozungulira ndi zakuthwa ndi zokhotakhota).

Kuphatikiza pa kupangidwa ndi zida zapadera, mapampu a centrifugal slurry nthawi zambiri amakhala ndi zomangira zosinthika kumbali yakutsogolo ndi kumbuyo kwa chosungira. Ndi ena opanga ma liner awa amatha kusintha pamene mpope ikuyenda. Izi zimalola malo opangira mchere, omwe nthawi zambiri amagwiritsidwa ntchito usana ndi usiku, kusintha chiwongolero cha mpope popanda kuzimitsa. Miyezo yopangira imakhalabe yayikulu ndipo pampu imayenda bwino kwambiri.

Pagulu la mapampu abwino osamuka, mapampu slurry nthawi zambiri mtundu wa pampu ya diaphragm yomwe imagwiritsa ntchito diaphragm yobwerezabwereza yoyendetsedwa ndi makina kapena ndi mpweya wopanikizidwa kuti ikule ndikugwirizanitsa chipinda chopopera. Pamene diaphragm ikukula, slurry kapena sludge amakokedwa m'chipindamo kudzera mu valve yomwe imalepheretsa kubwereranso. Pamene diaphragm ikugwirana, madzimadzi amakankhira kumbali yotulukira kunja kwa chipindacho. Mitundu ina yabwino yosamutsidwa ndi mapampu a pistoni ndi mapampu a plunger.

Kodi amagwiritsidwa ntchito kuti?

Mapampu a slurry ndi othandiza pakugwiritsa ntchito kulikonse komwe madzi okhala ndi zolimba za abrasive amakonzedwa. Izi zikuphatikiza migodi yayikulu, zonyamula matope, ndi malo opangira mchere. Kuphatikiza apo, amagwiritsidwa ntchito mumchenga ndi miyala, komanso muzomera zomwe zimapanga zitsulo, feteleza, miyala ya laimu, simenti, mchere, ndi zina zambiri. Amapezekanso m'malo ena opangira ntchito zaulimi komanso malo opangira madzi otayira.
