No ke aha he mea pono no ka tungsten carbide integral?

I loko o ka ʻoihana kemika lanahu, ka lepo a me nā mea ʻē aʻe o ka lawe ʻana i nā pipelines, ʻaʻole pili wale ka ʻāpana sealing o ka valve i ka friction sliding a me ka lole o nā ʻāpana kōkua sealing, akā e pale pū i ka hopena kiʻekiʻe o ka duplex gas-solid. ka hui ʻana me ka wela kiʻekiʻe a me ka paʻakikī kiʻekiʻe, a me ka uila a me ka cavitation i hoʻokumu ʻia e ka wai kaomi kiʻekiʻe, e alakaʻi ana i ka pōʻino a hoʻonāukiuki i ka hāʻule ʻole o ka valve.No laila, ma lalo o nā kūlana hana koʻikoʻi e like me ka lawe ʻana i ka pauka, ʻo ke kūpaʻa ʻana he mea koʻikoʻi koʻikoʻi ka loiloi loiloi o ka valve.

Koho mākou i ka integral sintered tungsten carbide e like me ka meae hana ʻO ka valve, ʻaʻole wale ka ikaika kiʻekiʻe, akā he kiʻekiʻe hoʻi ka hopena o ka honua, ke hoʻohana ʻia nā mea ʻē aʻe, ʻoi aku ka liʻiliʻi o ka friction coefficient ma mua o ke kila, hiki ke hoʻemi nui i ka friction o ka ʻili pili a hoʻemi pono i ka torque hana.

Hana ʻia ʻo Integral sintered tungsten carbide e ka hui ʻana o ka tungsten a me ke kalapona i ka wela kiʻekiʻe, ʻo ka hapa nui o ka tungsten carbide he paʻakikī kiʻekiʻe,pela no ʻAʻole maʻalahi ka decompose i ka wela kiʻekiʻe, akekahiloaʻa i ka pale oxidation maikaʻi.

I loko o ka pahu hoʻoheheʻe lanahu, ua hana ʻia ka valve disc a me ka noho valve me ka integral sintered tungsten carbide e hana i kahi paʻa hoʻopaʻa, a loaʻa i ka valve nā pōmaikaʻi aʻe.:

1 、Paʻakiki kiʻekiʻe.ʻo ka paʻakikī> 80HRC, hiki iā ia ke pale i ka hoʻoheheʻe nui ʻana o nā media particle multiphase e like me ka lanahu-wai slurry, pulverized lanahu, silica fume, etc.

2、Kūleʻa wela kiʻekiʻe.Hiki ke hana ma750°C ʻO ka wela kiʻekiʻe no ka manawa lōʻihi, a ʻo kona ikaika, adhesion a me ka hoʻonui wela ʻaʻole i kaupalena ʻia e ka mahana, e kū pono ana i nā kūlana wela kiʻekiʻe e like me ka ʻoihana kemika lanahu..

3 、Paʻi paʻi kiʻekiʻe.ʻO ka ikaika haʻihaʻi transverse o ka carbide tungsten sintered holoʻokoʻahikihiki i 4000MPa, ʻoi aku ma mua o 10 mau manawaof ke kila maʻamau.

4 、Paʻa ʻinoce.ʻO ka carbide cimented sintered holoʻokoʻa he paʻa kemika, ʻaʻole hiki ke hoʻoheheʻe ʻia i ka wai inā i wela, a ʻaʻole pili pū me ka waika hydrochloric a me ka waikawa sulfuric.

5 、Aʻāpalapala resistance.ʻO nā hiʻohiʻona o ka paʻakikī kiʻekiʻe a me ke kūpaʻa kiʻekiʻe o ka integral sintered cemented carbide e hōʻoia i ka hana anti-wear maikaʻi loa o ka sub-material sealing..

6 、Erosion Resistance.

Ma keʻano laulā, ʻo ka integral sintered tungsten carbide cemented carbide he kiʻekiʻe ka ikaika, kiʻekiʻe paʻakikī, kiʻekiʻe heheʻe helu, kiʻekiʻe paʻa, haʻahaʻa coefficient o friction, ʻaʻahu kū'ē, erosion kū'ē a me ka cavitation, corrosion kū'ē, a me ka hana 'ana o ka lole-kūpaʻa valve sila no. Hiki i nā kūlana hana koʻikoʻi ke hoʻomaikaʻi nui i ka hoʻohana ʻana o ka valve, hoʻonui i ka laulā hoʻohana o ka valve, a hoʻolōʻihi i ke ola hana o ka valve.

Hāʻawi ʻo Zhuzhou Chuangrui Cemented Carbide Co., Ltd. i nā mea ʻaʻahu kūʻokoʻa kiʻekiʻe a me ka ʻenehana hoʻopaʻa ʻana i ka ʻili o ka valve ʻoihana e hāʻawi i nā hopena no nā kūlana hana koʻikoʻi o ka ʻoihana kemika lanahu..
