Ke koho noi o ka electromagnetic flowmeter i ka ʻoihana hana meaʻai
2022-07-26
Hoʻohana pinepine ʻia nā kahe uila electromagnetic i nā flowmeters ʻoihana meaʻai, ka mea i hoʻohana nui ʻia e ana i ka nui o ka kahe o nā wai conductive a me nā slurries i nā pipeline i pani ʻia, me nā wai corrosive e like me nā waikawa, alkalis, a me nā paʻakai.
Pono nā hiʻohiʻona o ka Flowmeter no nā noi ʻoihana meaʻai: 1. ʻAʻole pili ke ana i nā loli i ka nui o ka wai, viscosity, wela, kaomi a me ka conductivity, 2. ʻAʻohe ʻāpana kahe o ke ana i loko 3. ʻAʻohe poho kaomi, koi haʻahaʻa no nā ʻāpana paipu pololei, 4. Hoʻohana ka mea hoʻololi i kahi ʻano hoʻoulu hou, me ka hoʻohana haʻahaʻa haʻahaʻa a me ka paʻa ʻole kiʻekiʻe. 5. Nui ka laula kahe ana, a o ka mea ana kahe ana he oihana ana elua, me ka huina mua, ka huina hoohuli a me ka huina okoa, a he nui na pukana.
Ke koho ʻana i ka mīkini kahe electromagnetic, e hōʻoia mua inā he conductive ke ana ʻana. ʻOi aku ka maikaʻi o ka kahe kahe o ka mea i ana ʻia i loko o nā mika uila electromagnetic maʻamau i ka 2 a 4m /s. I nā hihia kūikawā, ʻaʻole pono e emi ka haʻahaʻa haʻahaʻa ma mua o 0.2m /s. Loaʻa i nā ʻāpana paʻa, a ʻoi aku ka liʻiliʻi o ka kahe kahe maʻamau ma mua o 3m/s no ka pale ʻana i ka hakakā nui ma waena o ka lining a me ka electrode. No nā wai viscous, ʻoi aku ka nui o ka kahe kahe e kōkua i ka hoʻopau ʻana i ka hopena o nā mea viscous i hoʻopili ʻia i ka electrode, kahi mea e pono ai ka hoʻomaikaʻi ʻana i ke ana pololei. Hoʻolilo. ʻO ka maʻamau, koho ʻia ke anawaena nominal o ka pipeline kaʻina. ʻOiaʻiʻo, pono e noʻonoʻo ʻia ka pae kahe o ka wai i ka pipeline i ka manawa like. I ka liʻiliʻi a i ʻole ka nui o ka kahe kahe, pono ke koho ʻia ke anawaena nominal o ka flowmeter me ka kuhikuhi ʻana i ke kahe kahe ma lalo o ka manaʻo o ka hōʻoia ʻana i ka pololei o ke ana. Welina mai e hoʻokaʻaʻike i kā mākou poʻe loea no ke kākoʻo koho kikoʻī.
