Valavu ya Gulugufe Yopatukana Katatu Yowongolera Kuyenda kwa Mafakitale

Kusinthasintha kwa triple offset kumachepetsa kukhudzana mwachindunji pakati pa diski ndi mpando panthawi yotsegula ndi kutseka. Pakugwira ntchito kwenikweni, izi zimathandiza kuchepetsa kuwonongeka kwa malo otsekera ndikusunga mphamvu yogwirira ntchito yokhazikika, ngakhale mutabwerezabwereza. Poyerekeza ndi ma valve a gulugufe wamba, ndi oyenera kwambiri kutentha kwambiri komanso kupanikizika komwe kutsekeka kofewa sikothandiza.

Pa makina otsekera, pamwamba pa mpando ndi wolimba ndi Stellite® alloy. Izi zimathandiza kuti pakhale kukana dzimbiri, kukokoloka kwa nthaka, komanso kutentha. Mphete yotsekera yachitsulo yopangidwa ndi laminated idapangidwa kuti ipereke kulumikizana kofanana kuzungulira mpando, zomwe zimathandiza kuti ukhale wotetezeka nthawi zonse. Zigawo zotsekera zochokera ku grafiti zimagwiritsidwa ntchito kuti ziwongolere chitetezo cha moto ndikulola kuti zisinthe mosavuta panthawi yokonza.

Valavu imagwiritsa ntchito shaft ya chidutswa chimodzi kuti iwonetsetse kuti mphamvu ndi mphamvu yotumizira mphamvu yodalirika. Ma bearing amasankhidwa kuti agwire ntchito yolemera kwambiri ndikuchepetsa kuwonongeka panthawi yogwira ntchito. Dongosolo lolongedza, kuphatikiza ndi zinthu za graphite, cholinga chake ndikuwongolera kutuluka kwa madzi akunja ndikukwaniritsa zofunikira zomwe zimafala kwambiri pakugwiritsa ntchito mafakitale.

Kuchokera pa kukhazikitsa ndi kugwiritsa ntchito, valavu imakhala ndi chizindikiro chakunja, zomwe zimapangitsa kuti zikhale zosavuta kutsimikizira momwe zilili zotseguka kapena zotsekedwa m'munda. Malo otsekera a flange amapangidwa ndi makina kuti azikhala osalala bwino, zomwe zimathandiza kukonza kudalirika kwa kutsekera pamalumikizidwe a mapaipi.

Mtundu uwu wa valavu ya gulugufe wa triple offset umagwiritsidwa ntchito kwambiri pazinthu monga mafuta osakonzedwa, gasi wachilengedwe, nthunzi, madzi amadzimadzi, ma acid, madzi a m'nyanja, ndi mpweya wa mafakitale. Umagwiritsidwanso ntchito mu makina a geothermal, ma network otenthetsera m'madera, ndi njira zina zokhudzana ndi mphamvu.
