ʻO ka sensor kaomi 31Q4-40820 kūpono no nā ʻāpana excavator hou

Mea hoʻoemi kaomi

Hoʻohana nui ʻia ka sensor kaomi e ʻike i ke kaomi kino cylinder, ke kaomi ʻana i ka ea, hoʻonui i ka ratio o ka mīkini turbine, cylinder kūloko a me ka ʻaila.Hoʻohana nui ʻia ka ʻenekona hoʻoheheʻe ʻino e ʻike i ke kaomi suction, ke kaomi ʻino a me ke kaomi ʻaila.Hoʻohana nui ʻia ka Capacitance, piezoresistance, differential transformer (LVDT) a me ka nalu elastic surface (SAW) i nā mea ʻike kaomi kaʻa.

Hoʻohana nui ʻia ka sensor puʻe capacitive e ʻike i ke kaomi maikaʻi ʻole, ke kaomi hydraulic a me ke kaomi ea, me ke ana ʻana o 20 ~ 100kPa, nona nā hiʻohiʻona o ka ikehu hoʻokomo kiʻekiʻe, pane maikaʻi maikaʻi a me ka adaptability maikaʻi.Hoʻopili nui ʻia ka sensor piezoresistive pressure e ka wela, e koi ana i kahi kaʻa kaʻa uku wela, akā kūpono ia no ka hana nui.He puka nui ka LVDT pressure sensor, he maʻalahi ke hoʻopuka ma ke kelepona, akā maikaʻi ʻole ka anti-interference.Loaʻa i ka sensor kaomi ʻo SAW nā hiʻohiʻona o ka liʻiliʻi liʻiliʻi, ke kaumaha māmā, ka hoʻohana haʻahaʻa haʻahaʻa, ka hilinaʻi kiʻekiʻe, ka ʻike kiʻekiʻe, ka hoʻonā kiʻekiʻe, ka puka kikohoʻe, a me nā mea ʻē aʻe. .

ʻIke kahe

Hoʻohana nui ʻia ka sensor kahe e ana i ke kahe o ka ea a me ke kahe wahie o ka mīkini.Hoʻohana ʻia ke ana o ka holo ʻana o ka ea no ka ʻōnaehana hoʻokele engine e hoʻoholo ai i nā kūlana combustion, hoʻomalu i ka lākiō ea-wahie, hoʻomaka, ʻā a pēlā aku.ʻEhā ʻano ʻano o nā mea ʻike kahe ea: rotary vane (vane type), Carmen vortex type, hot wire type and hot film type.ʻO ka rotary vane air flowmeter he ʻano maʻalahi a me ka pololei o ke ana ʻana, no laila pono ke kahe ʻana o ka ea i ka uku wela.ʻO Carmen vortex air flowmeter ʻaʻohe wahi neʻe, ʻo ia ka maʻalahi a pololei, a pono hoʻi i ka uku wela.He kiʻekiʻe ke ana ʻana o ka mīkini ea uea wela a ʻaʻole pono ka uku wela, akā hiki ke hoʻopili ʻia e ka pulsation kinoea a me nā uea haki.Ua like ke ana ana o ka ea ki'i wela e like me ka ea uwea wela, aka, he uuku ka nui, kupono no ka hana nui a me ke kumu kuai.ʻO nā hōʻailona ʻenehana nui o ka sensor kahe ea: ʻo ka pae hana he 0.11 ~ 103 m3 / min, ʻo ka mahana hana -40 ℃ ~ 120 ℃, a ʻo ka pololei ʻo ≤1%.

Hoʻohana ʻia ka sensor kahe o ka wahie e ʻike i ke kahe wahie, ʻo ia hoʻi me ke ʻano huila wai a me ke ʻano pōpō pōʻai, me ke ʻano ikaika o 0 ~ 60kg / h, ka mahana hana o -40 ℃ ~ 120 ℃, pololei o 1% a me ka manawa pane o <10ms .
