Dipatimenti yaukadaulo yamadzimadzi ya BMG imapereka magawo osiyanasiyana ndikuthandizira machitidwe aukadaulo wamadzimadzi komanso ntchito zambiri zama mafakitale. Zogulitsazi zikuphatikizapo ma valve, ma hydraulic hoses ndi zopangira, accumulators, masilinda, osinthanitsa kutentha, ma hydraulic motors ndi mapaipi a hydraulic, komanso mapampu ndi zida za tank.
Mavavu ofunikira pagulu lazogulitsa za BMG amaphatikiza mavavu a InterApp Bianca ndi Desponia butterfly, omwe amalimbikitsidwa kuti agwiritse ntchito moyenera komanso motetezeka pamapulogalamu owongolera kayendetsedwe ka mafakitale.
Willie Lamprecht, BMG Fluid Technology Low Pressure Business Unit Manager anati: "Vavu yagulugufe yophatikizika imakhala ndi mawonekedwe oyenda bwino komanso zofunikira zocheperako, ndipo imagwiritsidwa ntchito mosiyanasiyana. Ikhoza kuonetsetsa ntchito yodalirika ngakhale m'malo ovuta kwambiri.
"Mosiyana ndi valavu ya mpira, diski ya gulugufe nthawi zonse imakhalapo mumsewu woyenda. Izi zikutanthauza kuti mosasamala kanthu za malo a valavu, zidzachititsa kutsika kwapakati pakuyenda. Mavavu ampira amatha kugwiritsidwa ntchito kudzipatula, pomwe mavavu agulugufe atha kugwiritsidwa ntchito motetezeka kudzipatula ndikuwongolera kuyenda.
“Poyerekeza ndi mitundu ina, ubwino umodzi wogwiritsa ntchito valavu ya gulugufe yozungulira kumanja ndi kamangidwe kake kooneka ngati kafila, mbali zocheperapo, kukonza kosavuta komanso kusamalidwa pang’ono.”
Mavavu agulugufe a BMG a InterApp Bianca ali ndi mzere wokhazikika wa PTFE komanso moyo wautali wautumiki, woyenerera madzi owononga komanso owononga komanso kugwiritsa ntchito komwe kuyeretsedwa kotheratu ndikofunikira.
Ma valve ogwira ntchito kwambiriwa ali pakati pa DN 32 ndi DN 900 kukula kwake ndipo amapangidwa ndi chitsulo cha ductile, carbon steel kapena matupi a zitsulo zosapanga dzimbiri kuti akwaniritse zofunikira za mafakitale onse. Mavavu agulugufe a Bianca amatha kukhazikitsidwa payekhapayekha ndi BMG kuti atsimikizire kugwira ntchito kodalirika komanso chitetezo chokwanira pamapulogalamu ena.
Mwachitsanzo, valavu ya Bianca (DN 50-DN 200) yogwirizana ndi FDA (DN 50-DN 200) ili ndi galasi lopukutidwa ndi chitsulo chosapanga dzimbiri komanso chinsalu choyera kwambiri cha PTFE kuti zitsimikizire chitetezo chopanga zinthu zogwiritsira ntchito mankhwala. Ndikofunikira kugwiritsa ntchito mavavu a Bianca okhala ndi ma discs okutidwa ndi PFA ndi PTFE lining pazambiri zowononga, zopangira mankhwala.
Ma valve otsatizanawa amagwiritsa ntchito ma discs osankhidwa mwapadera ndi zida zomangira, komanso amagwirizana ndi malangizo oletsa kuphulika ATEX 94/9EG, kuwonetsetsa kuti akugwira ntchito motetezeka m'malo ophulika.
Zodziwika bwino za mndandanda wa Bianca zikuphatikiza tchire lalitali, PFA disc kuchulukira pa shaft, ndi zisindikizo zachitetezo zodzaza moyo wonse, kuonetsetsa kuti shaft yodalirika yosindikizira komanso kusindikiza kwa shaft kwanthawi yayitali, ngakhale mumayendedwe ovuta komanso kutentha kwambiri.
Mphepete mwazitsulo zimalepheretsa kuzizira pamtunda wosindikiza wa flange, motero kumatalikitsa moyo wautumiki, pamene PTFE lining pamodzi ndi PFA overmolded disc imatsimikizira kugunda kochepa ndipo motero kumawonjezera moyo wa dongosolo. Zina zimaphatikizapo njira yosindikizira shaft yakunja kuti ateteze dzenje la khosi la valve komanso chitsamba chodzitchinjiriza chokha komanso chosasamalira. Ma tag a zitsulo zosapanga dzimbiri amalola kuti munthu azitha kufufuza bwinobwino.
BMG ili ndi magawo osiyanasiyana omaliza kuti apereke nthawi zazifupi, ngakhale mndandanda wa Bianca wokhala ndi kukula kwakukulu kwa DN 900.
Ma valavu agulugufe a Bianca amachotsa zidulo ndi zosungunulira mumigodi ndi matope; kukonza zowonjezera mumakampani amafuta ndi gasi komanso njira zowononga kwambiri mumakampani azitsulo. Mndandandawu ulinso woyenera kuyeretsa madzi kumene zonyansa zazing'ono ziyenera kupeŵedwa.
BMG's InterApp Desponia ndi Desponia Plus mavavu agulugufe apakati ali ndi thupi lolimba la valavu ndi kansalu kolimba ka elastomer, ndipo adapangidwa kuti azisintha bwino komanso zodalirika zamadzimadzi ndi mpweya m'malo osiyanasiyana.
Ma valve a Desponia akupezeka mu makulidwe kuchokera ku DN 25 mpaka DN 1600 ndi kupanikizika mpaka 16 bar, oyenera ntchito zosiyanasiyana zamafakitale. Mndandandawu ukhoza kupereka matupi achitsulo ndi ma ductile iron valve.
Kukula kwa mndandanda wa Desponia Plus uli pakati pa DN 25 ndi DN 600, yoyenera kugwiritsira ntchito kuthamanga kwambiri mpaka 20 bar, yoyenera kutentha kwambiri kapena ntchito za vacuum ndikukonzekera zokha. Mndandandawu ukhoza kupereka matupi a valve opangidwa ndi chitsulo cha ductile, chitsulo choponyedwa kapena chitsulo chosapanga dzimbiri.
Liner ndi gulugufe mbale za mndandandawu zimagwira ntchito yofunika kwambiri mu zotanuka zotanuka agulugufe, chifukwa ndi mbali ziwiri zokha zomwe zimakhudzana ndi madzimadzi. Flucast® liners ndi oyenera kugwiritsa ntchito abrasive komanso amagwirizana ndi FDA ndi EU malamulo.
Zodziwika bwino za mndandandawu zikuphatikizapo njira yosindikizira shaft yakunja yomwe imateteza dzenje la khosi la valve ndi mapangidwe a khosi lalitali omwe amalola kutsekemera kwa chitoliro. Gasket yokhazikika imapereka chitetezo pakuphulika, ndipo mphete ya O imamangidwa munjira ya shaft kuti ikhale gawo la njira yodalirika yosindikizira shaft.
Mlomo wosindikiza pamtunda wa flange umapereka chisindikizo changwiro, ndipo mawonekedwe okongoletsedwa a chinsalucho amatsimikizira kugwira bwino kwa thupi. Diski yoyendetsedwa ndi square imapereka kutumiza kwa torque kothandiza komanso kolimba, ndipo m'mphepete mwa disk yopukutira imachepetsa kukangana.
Mndandanda wa Desponia umatsimikizira kugwira ntchito kotetezeka mu njira zoyeretsera madzi, kupanga magetsi komanso kugwiritsa ntchito mankhwala osokoneza bongo. Ma valve amenewa amathanso kupirira ntchito zamakampani azitsulo, kumene ma valve otseka omwe amagwiritsidwa ntchito kuti afufuze zitsulo zosungunuka amakumana ndi zovuta. Mavavuwa okhala ndi ma discs apadera ophimbidwa ndi oyeneranso kumigodi ndi matope, ndipo amagwiritsidwa ntchito pochotsa zomwe zimafunikira ma valve okhala ndi kukana kwapamwamba kwambiri komanso kukana dzimbiri.
