SiC bushing, mbale, ma liners ndi mphete
Chonde onani kanema wa malonda patsamba lawebusayiti:
Zipinda zadothi zosagwiritsidwa ntchito ndi kuvala zimapereka chitetezo chabwino kwambiri komanso cholimba ku kuvulala. Zopangidwa makamaka kuti zigwiritsidwe ntchito kulikonse komwe kuvulala ndi kuvulala kuli vuto, zipinda za ZPC® zimachepetsa nthawi yogwira ntchito komanso kukonza. Zipinda zadothi za SiC zimalimbana kwambiri ndi kukwiya kwa zinthu zambiri monga silika, miyala, galasi, slag, phulusa la ntchentche, miyala yamwala, malasha, coke, chakudya, tirigu, feteleza, mchere ndi zinthu zina zolimba kwambiri.
Ma layers osapsa komanso osapsa ochokera ku Zhongpeng amagwirizana ndi mafakitale ambiri. Makasitomala osiyanasiyana kuyambira mafakitale a ufa mpaka mafakitale a malasha, magetsi, migodi ndi chakudya komwe ma nozzles a FGD amavomerezedwa kuti agwiritsidwe ntchito ku China Electric Power Group. Ma layers osapsa a ZPC amagulitsidwa ku United States, Canada, Australia, Mexico, South Africa, ndi zina zotero. Ndi abwino kwambiri pazinthu zomwe zimapsa kwambiri pogwira ntchito ndi kukonza zinthu za zomera. Ma layers a SiC, mbale ndi ma block ndi othandiza kwambiri pa ntchito monga mapaipi, ma tee, zigongono, zolekanitsa, ma cyclone, ma silo, ma bunker, ma trough a konkire ndi zitsulo, ma chute, ma impeller ndi ma agitator, ma fan blades ndi ma fan casings, ma conveyor screws, ma chain conveyor, ma mixer, ma pulpers; kulikonse komwe kupsa komwe kumabwera chifukwa cha kukangana kuli vuto.
Matailosi osapsa mtima kuti ateteze kuvulala, kuti akwaniritse mavuto enieni a kasitomala okhudza kuphwanyika, kukhudzidwa, ndi dzimbiri. Kugwiritsa ntchito zingwe zosagwirizana ndi kuvala za ZPC SiC pazinthu zovuta kumawonjezera ndalama zambiri chifukwa cha moyo wawo wautali wautumiki. Mtengo wa zida zosinthira, nthawi yogwira ntchito, kuyeretsa fakitale, ndi ndalama zokonzera zonse zachepa kwambiri. Ndalama zomwe zasungidwa zidzalipira zingwezo ndi kuziyika posachedwa.
Silikoni carbide sic bushing ndi mtundu watsopano wa zinthu zamakono komanso zosatha kutha padziko lonse lapansi. Inapangidwa ndi ufa wa silikoni carbide woyera kwambiri, wakuda wa kaboni woyera kwambiri komanso wotentha kwambiri komanso womangirira, mwa kutsanulira, kuchotsa zinthu zosayenera, kusungunula, ndi kuchotsa mchenga, wopangidwa ndi chinthu chopangidwa ndi zinthu zosakanikirana zomwe zimatha kutha.
Pakadali pano imagwiritsidwa ntchito ngati bushing mu zida zamigodi, monga mkuwa, golide, chitsulo, nickel ore ndi zina mu zitsulo zopanda chitsulo. Imagwira ntchito yolimba kwambiri, nthawi yogwiritsidwa ntchito ndi yoposa nthawi 10 kuposa bushing yachitsulo wamba ndi bushing ya alumina.
1. Kugwiritsa ntchito sic bushing mumakampani opanga migodi
Pa kudzaza mgodi, kunyamula ufa wothira ndi zinthu zina kumawononga kwambiri payipi. Nthawi yogwiritsira ntchito payipi yotumizira ufa wa ore yomwe imagwiritsidwa ntchito kale ndi yosakwana chaka chimodzi, ndipo tsopano silicon carbide bushings imatha kuwonjezera nthawi yogwiritsira ntchito ndi nthawi zoposa 10.
2. N’chifukwa chiyani ma linings a silikoni carbide amagwiritsidwa ntchito kwambiri mumakampani opanga migodi?
Chifukwa cha kukana kwa machubu a ceramic, zotsatirazi ndi kufananiza kukana kwa machubu a ceramic ndi zipangizo zina.
Kuyerekeza kwa kukana kwa kuvala kwa silicon carbide bushings
| Mayeso osiyanitsa mchenga (mchenga wa SiC) | Mayeso osiyanitsa a matope a 30% SiO2 | ||
| Zinthu Zofunika | Kuchuluka kwa voliyumu | Zinthu Zofunika | Kuchuluka kwa voliyumu |
| Chubu cha alumina cha 97% | 0.0025 | 45chitsulo | 25 |
| Chitsulo cha silicon carbide | 0.0022 | Chitsulo cha silicon carbide | 3 |
3. Zina zakuthupi ndi zamakina za mapaipi osagwira ntchito za ceramic mumakampani opanga migodi
| Zambiri za chinthucho zinthu | Mphamvu HV kg/mrn2 | Mphamvu yopindika MPa | Zinthu zapamwamba | Kuchuluka kwa zigawo za Ceramic g/cm3 | MP yolimba yopaka utoto | Kukana kugwedezeka kwa makina | Kukana kutentha kwa kutentha |
| Chubu chachitsulo | 149 | 411 | |||||
| SiC bushing | 1100-1400 | 300-350 | yosalala | 3.85-3.9 | 15-20 | 15 | 900 |
4. Chinthu china cha silicon carbide bushings chomwe chimagwiritsidwa ntchito m'migodi - kutayika pang'ono kwa kukana kuthamanga
Mayeso a kukana kwa ufa, slag ndi phulusa, zotsatira zake ndi izi:
| Zinthu Zofunika | Kusakhazikika kwathunthu （△） | Kusakhazikika kwathunthu (△/D) | Choyezera kukana madzi | ||
| Kutumiza kwamadzimadzi | Kutumiza kwa pneumatic | Kutumiza kwamadzimadzi | Kutumiza kwa pneumatic | ||
| Chubu chachitsulo wamba | 0.119 | 0.20 | 7.935×104 | 1.343×103 | 0.195 |
| Chitoliro chopangidwa ndi ceramic | 0.117 | 0.195 | 7.935×104 | 1.343×103 | 0.0193 |
5. Kulumikiza kwa silicon carbide bushing
（1）Pamene mapaipi osinthasintha amagwiritsidwa ntchito kulumikiza mapaipi oyika, kutalika kwa malo olowera kumapeto awiri a chitoliro chosinthasintha cha chitoliro kuyenera kusinthidwa mofanana. Kusiyana kwa kukula kuyenera kutengera momwe zinthu zilili m'deralo kapena zofunikira pa dipatimenti yokonza.
(2) Mukagwiritsa ntchito kulumikizana kwa flange, nkhope ya flange iyenera kukhala yosalala ndi kumapeto kwa chitoliro chophatikizana
Shandong Zhongpeng Special Ceramics Co., Ltd ndi imodzi mwa njira zazikulu kwambiri zothetsera zinthu zatsopano za silicon carbide ceramic ku China. SiC technical ceramic: Kuuma kwa Moh ndi 9 (Kuuma kwa New Moh ndi 13), komwe kumalimbana bwino ndi kukokoloka ndi dzimbiri, kukana bwino kwambiri - kukana komanso kukana okosijeni. Moyo wa ntchito wa SiC ndi wautali nthawi 4 mpaka 5 kuposa 92% alumina. MOR ya RBSiC ndi nthawi 5 mpaka 7 kuposa ya SNBSC, ingagwiritsidwe ntchito pazinthu zovuta kwambiri. Njira yowerengera mawu ndi yachangu, kutumiza kumakhala monga momwe kunalonjezera ndipo khalidwe lake ndi lapamwamba kwambiri. Nthawi zonse timapitilizabe kutsutsa zolinga zathu ndikubwezera mitima yathu kwa anthu.
