Chisindikizo chamafuta oyandama ndi dzina lodziwika bwino la zisindikizo zoyandama, zamtundu wa zisindikizo zamakina mu zisindikizo zosunthika.Ili ndi ntchito yabwino yosindikiza m'malo ovuta kugwira ntchito monga ufa wa malasha, sediment, ndi nthunzi yamadzi.Ndi chosindikizira chomangika chomwe chimagwiritsidwa ntchito kwambiri pa liwiro lotsika komanso pamavuto olemetsa.Ili ndi ubwino wa kukana kuvala, kubwezeredwa kokha pambuyo povala nkhope yomaliza, ntchito yodalirika, ndi mawonekedwe osavuta, ndipo imagwiritsidwa ntchito kwambiri mu makina opangira malasha.Monga makina oyendayenda a bulldozer, scraper conveyor head (mchira) sprocket components, roadhead loading mechanism ndi cantilever gawo, ng'oma zodula kumanzere ndi kumanja ndi zochepetsera makina opitilira migodi ya malasha, ndi zina zotero.
Zoyandamachisindikizo cha mafutaamagwiritsidwa ntchito pochepetsa mapulaneti a gawo loyenda la makina omanga kuti asindikize mwamphamvu kumapeto kwa gawolo.Chifukwa chodalirika kwambiri, imagwiritsidwanso ntchito ngati chisindikizo champhamvu cha shaft yotulutsa chidebe cha dredger.Chisindikizo chamtunduwu ndi cha zisindikizo zamakina ndipo nthawi zambiri chimakhala ndi mphete yoyandama yopangidwa ndi ferroalloy komanso chosindikizira cha nitrile rabara O-ring chisindikizo.Mphete zoyandama zimagwiritsidwa ntchito pawiri, imodzi imazungulira ndi gawo lozungulira ndipo ina imakhala yosasunthika, yomwe ili yosiyana kwambiri ndi mphete yosindikizira mafuta.
Chisindikizo chamafuta oyandama chimapangidwa ndi mphete ziwiri zofanana zachitsulo ndi mphete ziwiri za rabala.Mfundo yake yogwirira ntchito ndi yakuti mphete za mphira zimapanga malo otsekedwa ndi patsekeke (koma osakhudzana ndi tsinde) pansi pa chithandizo cha mphete zachitsulo.Pozungulira, malo awiri apansi a mphete zachitsulo amafanana kwambiri ndikugwedezana wina ndi mzake, kuonetsetsa kuti ntchito yabwino ikugwira ntchito kumbali imodzi, ndikutseka bwino fumbi lakunja, madzi, sludge, ndi zina zotero, kuteteza mafuta opaka mkati kuti asatayike.
Mfundo yosindikiza ya chisindikizo chamafuta oyandama ndikuti kusinthika kwa mphete ziwiri zoyandama zomwe zimachitika chifukwa cha kupindika kwa axial kwa O-ring kumapanga mphamvu yopondereza pamapeto osindikiza a mphete yoyandama.Ndi kuvala yunifolomu ya kusindikiza kumapeto kwa nkhope, mphamvu zotanuka zomwe zimasungidwa ndiRubber O-ringimatulutsidwa pang'onopang'ono, potero imasewera gawo la axial compensation.Malo osindikizira amatha kukhala omatira bwino mkati mwa nthawi yoikika, ndipo moyo wosindikiza wamba ndi wopitilira 4000h.
Zoyandamachisindikizo cha mafutandi mtundu wapadera wa makina osindikizira omwe amapangidwa kuti agwirizane ndi malo ogwirira ntchito ovuta.Ili ndi ubwino wa kukana kwamphamvu kwa kuipitsidwa, kukana kuvala, kukana kukhudzidwa, ntchito yodalirika, kubwezeredwa kokha chifukwa cha kuvala kumaso, ndi kapangidwe kosavuta.Amagwiritsidwa ntchito kwambiri pamakina opangira uinjiniya, ndipo amagwiritsidwanso ntchito kwambiri pazotengera zosiyanasiyana, zida zochizira mchenga, ndi zida za konkriti.M'makina opangira migodi ya malasha, amagwiritsidwa ntchito makamaka ngati sprocket ndi reducer of scraper conveyors, komanso njira yotumizira, rocker arm, drum, ndi mbali zina zamakina amigodi ya malasha.Mtundu woterewu wosindikiza umakhala wokulirapo komanso wokhwima pakugwiritsa ntchito makina ndi zida zauinjiniya, koma m'mafakitale ena, chifukwa chakugwiritsa ntchito pang'ono, kusowa kwa chidziwitso choyambira komanso chidziwitso chogwiritsa ntchito, kulephera pakugwiritsa ntchito kumakhala kofala, zomwe zimapangitsa kuti zikhale zovuta. kukwaniritsa zotsatira zoyembekezeka.
Sungani mpata wina pakati pa mphete yoyandama ndi tsinde lozungulira, lomwe limatha kuyandama momasuka, koma silingazungulire ndi shaft yozungulira.Imatha kungoyandama mozungulira ndikusunga malo enaake ndi shaft center pansi pa mphamvu yokoka.Mtsinjewo ukazungulira, madzi osindikizira (nthawi zambiri mafuta) amalowetsedwa kuchokera kunja kuti apange filimu yamafuta pampata pakati pa shaft ndi mphete yoyandama.Chifukwa cha mphamvu yamagetsi yamafuta yomwe imapangidwa panthawi yozungulira shaft, kuchuluka kwa filimu yamafuta kumasungidwa mkati mwa filimu yamafuta, kulola mphete yoyandama kuti isungike "kulumikizana" pakati pa shaft, kuchepetsa kwambiri kusiyana komanso moyenera. kukwaniritsa kusindikiza kwa fluid medium leakge.Ubwino wake ndi ntchito yosindikiza yokhazikika, kudalirika, ndi moyo wautali wautumiki;The ntchito chizindikiro osiyanasiyana chisindikizo ndi lonse (ndi kuthamanga ntchito mpaka 30 MPa ndi kutentha ntchito -100 ~ 200 ℃);Zoyenera makamaka kusindikiza ma media a gasi mu ma centrifugal compressor, sizingakwaniritsenso kutayikira kumlengalenga, ndipo ndizoyenera kusindikiza zoyaka, zophulika, zapoizoni, komanso zamtengo wapatali zamagesi.Choyipa ndichakuti zofunikira pakukonza mphete zoyandama ndizokwera, zomwe zimafunikira makina apadera osindikiza mafuta;Pali zambiri kutayikira mkati, koma iwo akadali a chikhalidwe cha kufalitsidwa mkati, amene qualitatively osiyana ndi kutayikira kwa makina zidindo.Amagwiritsidwa ntchito kwambiri pazisindikizo zamphamvu mu ma centrifugal compressor.
