Neft zarralari hisoblagichi uchun sinov standartlari qanday?

Sinov zarralari uchun sinov standartlari asosan ISO4406 va NAS1638 kiradi.
ISO4406 Standart
The ISO4406 standard divides oil contamination into 26 levels based on the size of particle concentration. The country has revised and improved the ISO4406 standard, and the revised ISO4406:1999 stipulates that the pollution level counted by an automatic particle counter is represented by three particle concentration levels of>4um,>6um, and>14um, ya'ni ISO4406 ifloslanish darajasini ifodalash uchun uchta raqamdan foydalangan holda.
NAS1638 standart
The NAS1638 standard categorizes particles in oil into 14 pollution levels, divided into five intervals based on particle size: 5-15, 15-25, 25-50, 50-100, and>100um. Har bir oraliq boshqa ifloslanish darajasiga bo'linadi.
Sinov usullari va jihozlari
Neft zarralarini aniqlashning asosiy usullari Fotores zarrachalari o'lchami o'lchash va mikroskop usuli. Fotorezist zarracha o'lchamini o'lchash usuli NAS1638 va ISO4406 standartlari uchun ko'proq mos keladi, mikroskop usuli kam ishlatiladi. Prudiy neft zarrachalari kattaligi kabi antotexnika fotorezist zarrachalarini o'lchash texnologiyasini ishlatadi va doimiy in'ektsiya tezligini va in'ektsiya hajmini aniq nazoratga etkazadigan bir nechta standartlar bilan jihozlangan. U ma'lumotlarni qayta ishlashning kuchli funktsiyalariga ega va to'g'ridan-to'g'ri sinovdan o'tkazilishi va aniqlanish natijalarini chop etishi mumkin.
