SiC bushing, ndiro, liner uye zvindori
Ndokumbira utarise vhidhiyo yechigadzirwa pawebhusaiti:
Pfeka zvisingaite ceramiclinings inopa yakanakisa kukanganisa uye abrasion inodzivirira kudzivirira. Kunyanya kugadzirirwa kushandiswa chero kupi nekupfeka uye mabrasion iri dambudziko, ZPC® linings inoderedza kuderera uye kugadzirisa. Iyo SiC ceramic linings inopokana zvakanyanya neabrasive mhedzisiro yezvinhu zvakawanda se silica, ore, girazi, slag, nhunzi madota, limestone, marasha, coke, chikafu, zviyo, fetiraiza, munyu uye zvimwe zvinokuvadza zvakanyanya.
Abrasion inodzivirira uye inopfeka inodzivirira linings kubva kuZhongpeng inokodzera maindasitiri mazhinji. Vatengi vanobva kuindasitiri yehupfu kuenda kumaindasitiri emarasha, emagetsi, emugodhi uye ezvekudya uko FGD nozzles inotenderwa kushandiswa muChina Electric Power Group. ZPC wear resistance linings dzinotengeswa muUnited States yose, Canada, Austrilia, Mexico, South Africa, etc. Dzakanaka kune zvidimbu zvemaraini zvinogona kukuvadzwa zvakanyanya mukubata zvinhu zvechirimwa nekugadzirisa mabasa. Iwo maSiC linings, mahwendefa uye zvivharo zvinoshanda mukushandisa semapombi, tei, magokora, zvinoparadzanisa, madutu, silos, bunkers, kongiri uye zvimwiro zvesimbi, chutes, impellers uye agitators, fan blades uye fan casings, conveyor screws, cheni conveyor, mixers, pulpers; chero kupi zvako friction-induced abrasion idambudziko.
Abrasion inodzivirira mataira ekudzivirira kupfeka, kusangana neabrasion chaiyo yemutengi, kukanganisa uye matambudziko ekuora. Kushandiswa kweZPC SiC kupfeka machira asingachinji pazvikamu zvine dambudziko kunowedzera mari yakawanda nekuda kwehupenyu hwavo hwesevhisi. Mutengo wekutsiva zvikamu, kuderera kwekushanda, kucheneswa kwechirimwa uye mutengo webasa rekugadzirisa zvese zvakadzikiswa zvakanyanya. Iko kuchengetwa kunoitwa kunobhadhara kune linings uye kuiswa munguva pfupi.
Silicon carbide sic bushing rudzi rutsva rwepamusoro-tekinoroji uye isingapfeki zvinhu munyika. Yakanga yakagadzirwa nepamusoro-kuchena silicon carbide poda, yakakwirira-kuchena kwepamusoro-tembiricha kabhoni dema uye mabhandi, nekudururira, kuvharika, sintering, uye jecha-kubvisa maitiro, akagadzirwa neyakaumbwa yakakwira kupfeka chigadzirwa.
Parizvino iri kushandiswa senge gwenzi mumidziyo yemugodhi, semhangura, goridhe, iron ore, nickel ore uye zvimwe mune zvisiri-ferrous simbi.Inoita basa rekusapfeka zvakanyanya, hupenyu hwekupfeka hunodarika kagumi kupfuura hwemazuva ese. simbi bushings uye alumina bushing.
1.Kushandiswa kwe sic bushing mumugodhi wemigodhi
Kuzadza mugodhi, pombi yehupfu uye miswe yakasakara papombi. Hupenyu hwesevhisi yepombi inotakura ore yakashandiswa kare haisviki gore rimwe, uye zvino sarudza silicon carbide bushings inogona kuwedzera hupenyu hwesevhisi nekupfuura. 10 nguva.
2.Sei silicon carbide linings inoshandiswa zvakanyanya muindasitiri yemigodhi?
Nekuda kwekupfeka kuramba kweceramic tubes, inotevera kuenzanisa kwekupfeka kuramba kweceramic tubes nezvimwe zvinhu.

5.Silicon carbide bushing connection
(1) Kana mapaipi anochinjika achishandiswa kubatanidza pombi dzekuisa, kureba kwekupinza kwemativi maviri eiyo inochinjika pombi sleeve inofanira kugadziridzwa symmetrically. Kuwedzera gaka kunofanirwa kuenderana nemamiriro enzvimbo kana zvinodiwa nedhipatimendi rekugadzira.
(2) Paunenge uchishandisa flange yekubatanidza, iyo flange kumeso inofanirwa kuve yakanyungudutswa nemagumo epombi inoumbwa.
Shandong Zhongpeng Special Ceramics Co., Ltd ndeimwe yeyakakura silicon carbide ceramic zvinhu zvitsva zvinogadziriswa muChina. SiC technical ceramic: Kuomarara kweMoh ndeye 9 (Kuoma kweMoh kutsva ndeye 13), nekupokana kwakanyanya kukukurwa nekuora, kunyura kwakanakisa - kuramba uye anti-oxidation. Hupenyu hwesevhisi yechigadzirwa cheSiC hwakareba 4 kusvika kashanu kupfuura 92% alumina zvinhu. Iyo MOR yeRBSiC ndeye 5 kusvika 7 nguva iyo yeSNBSC, inogona kushandiswa kune mamwe maumbirwo akaoma. Iyo quotation process inokurumidza, kuendesa kwakavimbiswa uye mhando ndeyechipiri kune imwe. Isu tinogara tichishingirira kupikisa zvinangwa zvedu uye nekudzorera moyo yedu kunharaunda.
