ʻO ka Nozzle Tungsten Carbide Kū'ē Kū'ē kiʻekiʻe no ka Petroleum a me ke kinoea kūlohelohe

Nozzle carbide simaua hana ʻia me ka mīkini kikoʻī a me nā mea carbide cemented. I ka hana ʻana i ka nozzle carbide cemented, hoʻokō mākou i ka wili pololei a me ka mālama ʻana i ka ʻili e hoʻokō ai i ka roughness lua o ra0.1 a ʻo ka roughness o nā ʻaoʻao ʻelua o R ʻo Ra0.025.Aia kahi radius ʻepekema o ka hoʻolālā curvature ma nā puka komo ʻelua.Mālama kēia hoʻolālā i ka hele mālie o ke kaula.Ma muli o ke kaʻina hana holoʻokoʻa, ʻaʻohe kihi kiʻekiʻe ma ka lua drilling, a ua hoʻomaikaʻi ʻia ka ʻano kulou a me ka pale ʻana i ka hoʻohālikelike ʻia me ka ruby ​​nozzle.Hana ʻia ka nozzle carbide sima ma ke kaomi wela a me ka sintering i ka lua pololei wela a me ka lua puʻu.Ma muli o kona paʻakikī, haʻahaʻa haʻahaʻa, ʻoi aku ka maikaʻi o ka ʻaʻahu a me ka corrosion, ua hoʻohana nui ʻia ka nozzle carbide cemented i ka hoʻoulu ʻana i ke one a me ka pana ʻana i nā lako peening, kahi e hōʻoia ai e hiki ke hoʻohana ʻia ka huahana i ka ea maikaʻi loa a me ka abrasive no ka manawa lōʻihi.
