Uphawu oluntantayo Umsebenzi osindayo we-hydraulic travel motor seal iqembu umemba ithrekhi Isilayishi esintantayo se-duo cone seal
Izinto zomkhiqizo
I-chromium alloy cast iron ephezulu
Ukuthwala ama-forgings ensimbi
Ububanzi besicelo
a.Lolu phawu lwamafutha antantayo alukwazi ukusebenza ngaphansi kwesimo sokucindezela okukhulu kanye nesivinini esiphezulu ngesikhathi esisodwa.
b.Ngaphansi kwezimo ezijwayelekile zokusebenza, lolu phawu lwamafutha e-shaft aluthwali ingcindezi.
c.I-Speed Cast iron: 3m/s (ngamafutha okugcoba)
100Cr6: 1m/s (ngamafutha okugcoba)
d.Izinga lokushisa -40 °C - +100 °C, elihlobene nezinto zenjoloba zokwenziwa ezisetshenzisiwe.
Izici Zomkhiqizo
Izinzuzo zayo wukuzinza kokubekwa uphawu kokusebenza, ukwethembeka nokuphila isikhathi eside;Uhlu olubanzi lwemingcele yokusebenza yokuvala (ingcindezi yokusebenza kuze kufike ku-30 MPa, izinga lokushisa lokusebenza -100 ~ 200 ° C);Ilungele ukuvala indawo yegesi ku-compressor ye-centrifugal, futhi ayikwazi futhi ukubona ukuthi akukho ukuvuza endaweni yomoya, ifanele ukuvalwa kwemithombo yegesi evuthayo, eqhumayo, enobuthi neyigugu.
Izindaba ezidinga ukunakwa
I-1) Ngaphambi kokufaka uphawu lwamafutha antantayo, kuyadingeka ukuhlola ukuthi ingaphezulu lephephabhuku libuhlungu kakhulu nokuthi zikhona yini izibazi, ikakhulukazi izibazi ezinde eduze kwe-axial direction.Uma indawo yejenali ilukhuni kakhulu, kulula ukulimaza isivalo sikawoyela noma ukusheshisa ukugqokwa kodebe ngo-1:3, kulimaze ukusebenza kwayo kokuvala.Uma ingaphezulu lejenali libangelwa izibazi ezingathi sína zomthelela ngenxa yokuhlakazeka nokuhlanganiswa okungafanele, kuzokwenza udebe lwesici sikawoyela nobuso bejenali bulingane ngokuxekethile, okuholela ekuvuzeni kukawoyela.Kulezi zimo ezimbili ezingenhla, ngemva kokufaka ingxenye yesibazi, i-lathe ingabuye iguqulwe ngokuvumelana nosayizi wejenali eshiwo, noma kushintshwe shaft entsha.Uma ijenali inama-metal burrs noma i-shaft head flying edge kuphela, ifayela lingasetshenziswa ukunquma nokushelela, ukuvimbela ukulimala kwezindebe ze-oil seal lapho kufakwa uphawu lwamafutha.
(2) Hlola ukuthi udebe lwamafutha antantayo luphukile, lonakele noma lugqwalile.Uma kukhona lezi zenzakalo ezingathandeki, uphawu olusha lukawoyela kufanele lufakwe esikhundleni.
(3) Lapho ufaka uphawu lwamafutha ohlaka lwamathambo olunophawu lwamafutha antantayo, amathuluzi okufaka akhethekile kufanele asetshenziselwe ukuvimbela udebe lophawu lwamafutha ukuthi lunganwetshwa futhi lukhubazeke noma lonakaliswe ngokuklwejwa.Uma lingekho ithuluzi elinjalo, le ndlela elandelayo ingasetshenziselwa ukufakwa: okokuqala, gingqa ungqimba lwefilimu yepulasitiki eqinile (eyaziwa ngokuthi i-cellophane) kujenali ngisho nasekhanda le-shaft, gcoba amafutha amancane phezulu, faka uphawu lwamafutha ekhanda le-shaft eligoqwe ngefilimu yepulasitiki, ngokulinganayo phoqa uphawu lwamafutha kancane kancane luphushele kujenali, bese ukhipha ifilimu yepulasitiki.Qaphela: Ungafaki indlela engafanele yodebe, kufanele ibe ngaphakathi kwendawo yokugcina uwoyela, uhlangothi olunezimpawu zokuthengisa kanye nemininingwane ebheke ngaphandle.Ngoba umlomo 1:3 ungavalwa ngendlela eyodwa kuphela, uma uphawu lwamafutha luhlanekezelwe, nakanjani lubangela ukuvuza kwamafutha, lwenza buthaka umphumela wokuvala noma ukwehluleka.Gwema ukubeka uphawu lwamafutha lugobile noma ukusebenzisa isando namanye amathuluzi ukuze ungqongqoze indawo yophawu lwamafutha, ngaphandle kwalokho kulula ukulimaza uphawu lwamafutha.
4Uma isiphethu esiziqinisayo sikhululekile, amandla okunwebeka ayancipha, futhi iziphetho ezimbili zingaqhubeka nokusetshenziswa.
