Mpaka mwezi wa February 2020, malo osungira mafuta padoko la ku Brazil ankagwiritsa ntchito mapampu awiri apakati ponyamula mafuta olemera kuchokera ku matanki osungira mafuta kupita ku magalimoto onyamula mafuta kapena zombo. Izi zimafuna jekeseni wamafuta a dizilo kuti muchepetse kukhuthala kwakukulu kwa sing'anga, yomwe ndi yokwera mtengo. Eni ake amapeza ndalama zosachepera $2,000 patsiku. Kuphatikiza apo, mapampu a centrifugal nthawi zambiri amalephera chifukwa cha kuwonongeka kwa cavitation. Mwiniyo adaganiza zosintha imodzi mwa mapampu awiri apakati ndi NOTOS® multiscrew pump yochokera ku NETZSCH. Chifukwa cha mphamvu yake yabwino kwambiri yoyamwa, mpope wa 4NS wosankhidwayo ndi woyenereranso kumvetsera nyimbo zowoneka bwino kwambiri mpaka 200,000 cSt, zomwe zimatuluka mpaka 3000 m3/h. Pambuyo pa kutumidwa, zinaonekeratu kuti pampu ya multiscrew imatha kugwira ntchito popanda cavitation ngakhale pamayendedwe apamwamba kwambiri poyerekeza ndi mapampu ena a centrifugal. Ubwino wina ndikuti sikufunikanso kuwonjezera mafuta ambiri a dizilo. Kutengera zomwe zachitika zabwinozi, mu February 2020 kasitomala adaganizanso zosintha pampu yachiwiri ya centrifugal ndi NOTOS ®. Kuphatikiza apo, zikuwonekeratu kuti kugwiritsa ntchito mphamvu kumatha kuchepetsedwa kwambiri.
"Mapampuwa amagwiritsidwa ntchito kunyamula mafuta olemera kuchokera kumafamu akasinja kupita ku magalimoto onyamula mafuta kapena sitima zapamadzi ku madoko a kumpoto chakum'mawa kwa Brazil, makamaka panthawi ya chilala," akufotokoza Vitor Assmann, Senior Sales Manager ku NETZSCH Brazil. "Izi ndichifukwa choti mafakitale opangira magetsi opangira magetsi mdziko muno amatulutsa mphamvu zochepa panthawiyi, zomwe zimachulukitsa kuchuluka kwamafuta ambiri. Mpaka February 2020, kusamutsaku kunachitika pogwiritsa ntchito mapampu awiri a centrifugal, komabe pampu yapakati iyi idalimbana ndi kukhuthala kwakukulu." chilengedwe. "Mapampu apakati omwe amakhalapo amakhala osakoka bwino, zomwe zikutanthauza kuti mafuta ena amakhalabe m'nkhokwe ndipo sangathe kugwiritsidwa ntchito," akufotokoza motero Vitor Assmann. "Kuphatikiza apo, ukadaulo wolakwika ungayambitse cavitation, zomwe zingayambitse kulephera kwa mpope kwa nthawi yayitali."
Mapampu awiri a centrifugal pa famu ya tanki yaku Brazil akuvutikanso ndi cavitation. Chifukwa cha kukhuthala kwakukulu, mtengo wa NPSHa wa dongosololi ndi wotsika, makamaka usiku, zomwe zimapangitsa kuti pakhale kufunika kowonjezera mafuta a dizilo okwera mtengo kuti achepetse kukhuthala. “Pafupifupi malita 3,000 ayenera kuwonjezeredwa tsiku lililonse, zomwe zimawononga ndalama zosachepera $2,000 patsiku,” Asman anapitiriza. Kuti apititse patsogolo kudalirika kwa ndondomeko komanso kuchepetsa mphamvu zamagetsi, mwiniwakeyo adaganiza zosintha imodzi mwa mapampu awiri a centrifugal ndi NOTOS ® multiscrew pump kuchokera ku NETZSCH ndikuyerekeza momwe ma unit awiriwa akuyendera.
Mitundu ya NOTOS ® nthawi zambiri imaphatikizapo mapampu a multiscrew okhala ndi ziwiri (2NS), zitatu (3NS) kapena zinayi (4NS) zomangira, zomwe zingagwiritsidwe ntchito mosinthasintha kuti zigwirizane ndi ma viscosity osiyanasiyana komanso ngakhale kuthamanga kwakukulu. Malo osungiramo mafuta ku Brazil ankafuna mpope wokhoza kupopa mafuta olemera mpaka 200 m3/h pamphamvu ya 18 bar, kutentha kwa 10-50 °C ndi viscosity yofikira 9000 cSt. Mwini famu ya thankiyo adasankha pampu ya 4NS twin screw, yomwe imatha kufika 3000 m3/h ndipo ndiyoyenera kuwonera makanema owoneka bwino kwambiri mpaka 200,000 cSt.
Pampu ndi yodalirika kwambiri, imatha kupirira kuthamanga kowuma ndipo imatha kupangidwa kuchokera kuzinthu zomwe zasankhidwa kuti zigwiritsidwe ntchito. Ukadaulo wamakono wopanga amalola kulolerana kolimba pakati pazigawo zosunthika komanso zosasunthika, potero zimachepetsa kufunika kwa kusefukiranso. Kuphatikizana ndi mawonekedwe a chipinda chopopera choyenda bwino, kuchita bwino kwambiri kumatheka.
Komabe, kuwonjezera pakuchita bwino, kusinthasintha kwa mpope molingana ndi kukhuthala kwa sing'anga yopopera ndikofunikira makamaka kwa eni minda yama tanki aku Brazil: "Ngakhale kuti mapampu a centrifugal amagwira ntchito pang'onopang'ono ndipo kukhuthala kumawonjezeka, mphamvu yawo imachepa kwambiri. The NOTOS® multiscrew pump imagwira ntchito bwino kwambiri pamtundu wonse wa viscosity Manager. "Lingaliro lopopera ili limachokera ku mgwirizano pakati pa auger ndi nyumba." Amapanga chipinda choyendera momwe sing'anga imayenda mosalekeza kuchokera kumbali yolowera kupita ku mbali yotulutsa pansi pa kupanikizika kokhazikika - pafupifupi mosasamala kanthu za kusasinthasintha kapena kukhuthala kwa sing'anga. Kuthamanga kwa madzi kumakhudzidwa ndi liwiro la mpope, m'mimba mwake ndi phula la auger. Chifukwa chake, imagwirizana mwachindunji ndi liwiro ndipo imatha kusinthidwa bwino kudzera mu izi.
Mapampuwa amatha kusinthidwa kuti agwiritse ntchito panopa kuti akwaniritse ntchito yabwino. Izi zimakhudza makamaka miyeso ya mpope ndi kulolerana kwake, komanso zowonjezera. Mwachitsanzo, ma valve oponderezedwa, makina osindikizira osiyanasiyana ndi zida zowunikira pogwiritsa ntchito masensa a kutentha ndi kugwedezeka angagwiritsidwe ntchito. "Kwa ntchito ya ku Brazil, kukhuthala kwa ma TV pamodzi ndi liwiro la mpope kunkafuna kusindikiza kawiri ndi njira yosindikizira kunja," akufotokoza Vitor Assmann. Pa pempho la kasitomala, kapangidwe kake kamagwirizana ndi zofunikira za API.
Chifukwa 4NS imatha kugwira ntchito m'malo owoneka bwino kwambiri, palibe chifukwa chobaya mafuta a dizilo. Izi, nazonso, zidachepetsa ndalama ndi $2,000 patsiku. Kuphatikiza apo, pampu imagwira ntchito bwino kwambiri popopera ma viscous media, kuchepetsa kugwiritsa ntchito mphamvu kuposa 40% mpaka 65 kW. Izi zimapulumutsa ndalama zowonjezera mphamvu, makamaka pambuyo poyeserera bwino mu February 2020, pampu yachiwiri yomwe ilipo ya centrifugal idasinthidwanso ndi 4NS.
Kwa zaka zoposa 70, NETZSCH Pumps & Systems yakhala ikugwira ntchito pamsika wapadziko lonse ndi NEMO® single screw pumps, TORNADO® rotary vane pampu, NOTOS® multiscrew pump, PERIPRO® peristaltic pump, grinders, makina ochotsera ng'oma, zipangizo za dosing. ndi zowonjezera. Timapereka mayankho makonda, omveka bwino pamagwiritsidwe ntchito m'mafakitale osiyanasiyana. Ndi antchito opitilira 2,300 komanso chiwongola dzanja cha €352 miliyoni (chaka chachuma cha 2022), NETZSCH Pumps & Systems ndiye gawo lalikulu lazamalonda mu NETZSCH Gulu lomwe lapeza ndalama zambiri, limodzi ndi NETZSCH Analysis & Testing ndi NETZSCH Grinding & Dispersion. Miyezo yathu ndi yapamwamba. Timalonjeza makasitomala athu "Proven Excellence" - zinthu zabwino kwambiri ndi ntchito m'madera onse. Kuyambira 1873, tatsimikizira mobwerezabwereza kuti tingathe kusunga lonjezoli.
