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 i nā kūlana combustion, kaohi ʻana 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 ke kinoea pulsation a me nā uea haki. Ua like ke ana ana o ka ea ki'i wela ea 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 .
