(Tuam Tshoj) YYP-J20 Lim Paper Pore Size Tester
Qhov ntsuas yog qhov me me, lub teeb hauv qhov hnyav, txav tau yooj yim thiab yooj yim rau kev khiav lag luam. Siv cov cuab yeej siv hluav taws xob zoo tshaj plaws, qhov ntsuas nws tus kheej tuaj yeem xam qhov siab tshaj plaws aperture tus nqi ntawm daim ntawv xeem ntev npaum li tus nqi ntawm cov kua dej ntws tawm.
Tus nqi aperture ntawm txhua daim ntawv xeem thiab tus nqi nruab nrab ntawm ib pawg ntawm cov ntawv xeem tau luam tawm los ntawm lub tshuab luam ntawv. Txhua pawg ntawm cov ntawv xeem tsis yog ntau tshaj 5. Cov khoom no feem ntau yog siv rau kev txiav txim siab ntawm qhov siab tshaj plaws ntawm cov ntawv lim siv nyob rau hauv combustion engine lim.
Lub hauv paus ntsiab lus yog tias raws li lub hauv paus ntsiab lus ntawm kev ua capillary, tsuav yog qhov ntsuas huab cua raug yuam los ntawm qhov pore ntawm cov khoom ntsuas ntsuas los ntawm cov kua, kom cov huab cua raug tshem tawm ntawm cov kua hauv qhov loj tshaj plaws pore raj ntawm cov khoom kuaj. , lub siab xav tau thaum thawj npuas tawm ntawm lub qhov pore, siv qhov paub nro ntawm cov kua dej ntawm qhov ntsuas kub, Qhov siab tshaj plaws aperture thiab nruab nrab aperture ntawm daim ntawv xeem tuaj yeem xam los ntawm kev siv qhov sib npaug capillary.
